Rep Culberson Wants NASA to Launch Starship on 100th Anniversary of Apollo 11 Landing

It seems that the recently announced Breakthrough Starshot project—to send a privately funded fleet of tiny spacecraft to a nearby star—may have started a star rush. Today a senior U.S. lawmaker who helps write NASA’s budget called on the agency to begin developing its own interstellar probes, with the aim of launching a mission to Alpha Centauri, our nearest star system, in 2069—the centenary of the Apollo 11 moon landing.

Representative John Culberson (R–TX), a self-professed space fan who chairs the House of Representatives appropriations subpanel that oversees NASA, included the call for the ambitious voyage in a committee report released today. The report accompanies a bill setting NASA’s budget for the 2017 fiscal year, which begins 1 October; the full House appropriations panel is set to consider the bill on Tuesday.

In the report, Culberson’s panel “encourages NASA to study and develop propulsion concepts that could enable an interstellar scientific probe with the capability of achieving a cruise velocity of 0.1c [10% of the speed of light].” The report language doesn’t mandate any additional funding, but calls on NASA to draw up a technology assessment report and conceptual road map within 1 year.

SpaceX Bringing in Lawyers in Support of its 2018 Mars Mission

A manned mission to Mars is a hot topic in space, and has been for a long time. Most of the talk around it has centred on the required technology, astronaut durability, and the overall feasibility of the mission. But now, some of the talk is focussing on the legal framework behind such a mission.

Lockheed Proposals for Deep Space Exploration

At a House Space Subcommittee meeting on Capitol Hill last week, several companies laid out plans for deep space exploration. Lockheed Martin Vice President Wanda A. Sigur discussed the Orion Multi-Purpose Crew Vehicle the company is building for NASA, proposed cis-lunar space operations, and a Mars base camp orbiting the Red Planet.

Orbital ATK Proposes Lunar Space Station by 2020

Orbital ATK has unveiled preliminary plans to place a four-person habitat in cislunar space by 2020. The announcement during testimony to the U.S. House of Representatives Subcommittee on Space would not only see the creation of a permanent human presence in lunar orbit by the start of the next decade, but would potentially provide a wealth of regularly-scheduled missions for SLS and Orion.

ESA Begins Building Service Module for NASA Orion Capsule

NASA and European Space Agency officials on May 19 said the European Service Module (ESM) for NASA’s Orion crew-transport vehicle was within budget and on schedule for a late-2018 inaugural flight pending a key review.

But the ESM program remains pressed for time – so much so that flight-model hardware integration is beginning before the program’s critical design review, scheduled for June 16 at ESA’s Estec facility in Noordwijk, Netherlands.

Fully loaded and fueled, the ESM will weigh about 13,000 kilograms at launch and provide Orion’s propulsion, power supply, thermal control and crew life-support elements.

It is the first time that NASA has allowed Europe to occupy such a crucial place in an astronaut-related program and signals the mutual respect between agencies that may be one of the enduring contributions of the international space station.

NASA to get $19.5 Billion in House Budget, Europa Orbiter & Lander get $260M

The House Appropriations Committee has released a spending bill that would give NASA a budget of $19.5 billion for fiscal year 2017, which is $500 million above President Barack Obama’s request. The measure boosts spending for exploration and science programs.


US Military needs to Prepare for Missile Swarms

The U.S. Air Force relies on more than 5,000 aircraft to give it unmatched dominance over every other competitor on earth. The U.S. Navy, for its part, counts on more than 3,700 aircraft and 273 deployable battle force ships, which constitute the largest and most technologically advanced sailing branch in the world.

This much is true — no country can possibly hope to challenge the United States with military means on a global scale and win. But key to America’s global strength are huge air and naval bases which are vulnerable to being overwhelmed and destroyed by swarms of precision-guided weapons in a limited, regional war.

The Navy also cannot expect its ships to survive if they come under attack by sufficiently large numbers of cruise missiles and ballistic missiles of the kind now fielded by China. While better protected from missiles than bases, the current breadth of U.S. technology and doctrine cannot compensate for this weakness.

The result is that the Pentagon must radically rethink its missile defenses, or risk serious losses in the opening hours of a future conflict. But according to a recent report, the solution could be lots of futuristic lasers, guns and electromagnetic weapons that can engage enormous numbers of incoming missiles at relatively short ranges.

General Atomics Commiting Over $50 Million to Developing its 10 MJ Railgun

Meemannia eos: The Earliest Known Ray-Finned Fish From Lochkovian Devonian China


Osteichthyans, or bony fishes, comprise two categories, each containing over 32,000 living species: Sarcopterygii (lobe-finned fishes and tetrapods) and Actinopterygii (ray-finned fishes). Nevertheless, actinopterygians have an obscure early evolutionary history. The earliest definitive actinopterygian is the Middle Devonian (Eifelian) Cheirolepis, with earlier candidates generally represented by fragments subject to differing phylogenetic interpretations. By contrast, earliest Devonian deposits yield a diversity of lobe-finned fishes and recent discoveries from China extend their origin into the late Silurian.

The Early Devonian (Lochkovian) Xitun Formation of Yunnan, China, provides remarkable fossils to illustrate the evolutionary origins of individual sarcopterygian lineages, but apparently lacks any actinopterygians. Meemannia is the newest--and least understood--member of this fauna. Represented by four isolated skull roofs and a referred jaw, Meemannia presents an intriguing mosaic of characteristics: histology interpreted as a precursor to the "cosmine" of rhipidistian sarcopterygians (lungfishes plus tetrapods) combined with an undivided braincase and skull roof resembling that of actinopterygians. Previous phylogenetic analyses placed Meemannia as the earliest-diverging sarcopterygian, based on histological features.

How Plants Conquered the Land 500 Million Years Ago

Research at the University of Leeds has identified a key gene that assisted the transition of plants from water to the land around 500 million years ago.

The ANR gene is required to tolerate 'extreme dehydration' in the moss Physcomitrella patens, a land plant that is used as an experimental model.

Researchers at the Centre for Plant Sciences at the University found that the ANR gene - present in the most ancient land plants - was inherited from ancestral fresh water algae.

The ANR gene has since been lost in the evolution of seed plants. The results are published today in the American Society of Plant Biology's journal The Plant Cell.

Dr Andrew Cuming, who led the research, said: "This gene hadn't been identified so far because most research until now has focused on modern flowering plants.

More on Why Mt Gox Failed

When Mark Karpeles, the CEO of what was once the world’s largest Bitcoin exchange, said that the company had gone bankrupt because 800,000 bitcoins (worth nearly half a billion dollars at the time) had been hacked, he wasn’t exactly lying. He wasn’t exactly telling the whole truth, either, but there was an intriguing element of fact.

At least 80,000 had been hacked before Karpeles even took over the company, and that initial cyber theft began a spiral of trouble that may have led directly to the firm’s financial collapse.

This week The Daily Beast obtained internal emails, contracts,, and other documents related to the implosion of Karpeles’s company, Mt. Gox. Along with information provided by a former employee who handled accounting for the firm, the documents reveal previously unreported details about how Mt. Gox failed, and why.


Characterizing Titan's Atmospheric Aerosols

Characterization of aromaticity in analogues of titan's atmospheric aerosols with two-step laser desorption ionization mass spectrometry

Authors:

Mahjoub et al

Abstract:

The role of polycyclic aromatic hydrocarbons (PAH) and Nitrogen containing PAH (PANH) as intermediates of aerosol production in the atmosphere of Titan has been a subject of controversy for a long time. An analysis of the atmospheric emission band observed by the Visible and Infrared Mapping Spectrometer (VIMS) at 3.28 micrometer suggests the presence of neutral polycyclic aromatic species in the upper atmosphere of Titan. These molecules are seen as the counter part of negative and positive aromatics ions suspected by the Plasma Spectrometer onboard the Cassini spacecraft, but the low resolution of the instrument hinders any molecular speciation.

In this work we investigate the specific aromatic content of Titan's atmospheric aerosols through laboratory simulations. We report here the selective detection of aromatic compounds in tholins, Titan's aerosol analogues, produced with a capacitively coupled plasma in a N2:CH4 95:5 gas mixture. For this purpose, Two-Step Laser Desorption Ionization Time-of-Flight Mass Spectrometry (L2DI-TOF-MS) technique is used to analyze the so produced analogues. This analytical technique is based on the ionization of molecules by Resonance Enhanced Multi-Photon Ionization (REMPI) using a {\lambda}=248 nm wavelength laser which is selective for aromatic species. This allows for the selective identification of compounds having at least one aromatic ring. Our experiments show that tholins contain a trace amount of small PAHs with one to three aromatic rings. Nitrogen containing PAHs (PANHs) are also detected as constituents of tholins. Molecules relevant to astrobiology are detected as is the case of the substituted DNA base adenine.

Martian north polar cap summer water cycle

Martian north polar cap summer water cycle

Authors:

Brown et al

Abstract:

A key outstanding question in Martian science is 'are the polar caps gaining or losing mass and what are the implications for past, current and future climate?' To address this question, we use observations from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) of the north polar cap during late summer for multiple Martian years, to monitor the summertime water cycle in order to place quantitative limits on the amount of water ice deposited and sublimed in late summer.

We establish here for the first time the summer cycle of water ice absorption band signatures on the north polar cap. We show that in a key region in the interior of the north polar cap, the absorption band depths grow until Ls=120, when they begin to shrink, until they are obscured at the end of summer by the north polar hood. This behavior is transferable over the entire north polar cap, where in late summer regions 'flip' from being net sublimating into net condensation mode. This transition or 'mode flip' happens earlier for regions closer to the pole, and later for regions close to the periphery of the cap.

The observations and calculations presented herein estimate that on average a water ice layer ~70 microns thick is deposited during the Ls=135-164 period. This is far larger than the results of deposition on the south pole during summer, where an average layer 0.6-6 microns deep has been estimated by Brown et al. (2014).

NASA Trying to Pull Forward the First SLS Launch From November to September 2018

Managers of three key NASA exploration programs said May 10 that they are making good progress towards a first launch of the Space Launch System heavy-lift rocket as soon as September 2018.

Managers of the SLS, Orion, and Ground Systems Development and Operations (GSDO) programs said at a Space Transportation Association luncheon here that while the programs are working towards a first launch of SLS and Orion, called Exploration Mission 1 (EM-1), in November 2018, they believe that they could launch up to two months earlier.

“The agency’s baseline commitment is November of 2018,” said Mike Bolger, manager of the GSDP program. “The September date we’ve talked internally about, and pressed them to see if we can make it by September. It gives us a little margin at the end.”

His comments came after an earlier presentation by Mark Kirasich, the Orion program manager, who discussed preparations for the EM-1 launch, including photos of the pressure vessel of the spacecraft being assembled at the Kennedy Space Center.

“This is the pressure vessel that, about 28 months from now, will be on its way towards the moon and into a distant retrograde orbit around the moon,” he said, a timeframe that corresponds to a September 2018 launch.

Cephalopods may be Spreading due to Climate Change

Humans have changed the world's oceans in ways that have been devastating to many marine species. But, according to new evidence, it appears that the change has so far been good for cephalopods, the group including octopuses, cuttlefish, and squid. The study reported in the Cell Press journal Current Biology on May 23 shows that cephalopods' numbers have increased significantly over the last six decades.

"The consistency was the biggest surprise," says Zoë Doubleday of Australia's Environment Institute at the University of Adelaide. "Cephalopods are notoriously variable, and population abundance can fluctuate wildly, both within and among species. The fact that we observed consistent, long-term increases in three diverse groups of cephalopods, which inhabit everything from rock pools to open oceans, is remarkable."

According to the researchers, there has been growing speculation that cephalopod populations were proliferating in response to a changing environment, based partly on trends in cephalopod fisheries. Cephalopods are known for rapid growth, short lifespans, and extra-sensitive physiologies, which may allow them to adapt more quickly than many other marine species.

Terrestrial Effects Of Nearby Supernovae In The Early Pleistocene

Terrestrial Effects Of Nearby Supernovae In The Early Pleistocene

Authors:

Thomas et al

Abstract:

Recent results have strongly confirmed that multiple supernovae happened at distances ~100 pc consisting of two main events: one at 1.7 to 3.2 million years ago, and the other at 6.5 to 8.7 million years ago. These events are said to be responsible for excavating the Local Bubble in the interstellar medium and depositing 60Fe on Earth and the Moon. Other events are indicated by effects in the local cosmic ray (CR) spectrum. Given this updated and refined picture, we ask whether such supernovae are expected to have had substantial effects on the terrestrial atmosphere and biota. In a first cut at the most probable cases, combining photon and cosmic ray effects, we find that a supernova at 100 pc can have only a small effect on terrestrial organisms from visible light, but tropospheric ionization due to the penetration of ≥ TeV cosmic rays will increase by nearly an order of magnitude for thousands of years, and irradiation by muons on the ground and in the upper ocean will increase 20-fold, which will approximately triple the overall radiation load on terrestrial organisms. These effects make possible changes in climate and increased cancer and mutation rates. Further research on the effects of these changes is needed.

A Review of Kuehneotherium & its Mammaliaforme Relatives From Upper Triassic France

The Kuehneotheriidae (Mammaliaformes) from Saint-Nicolas-de-Port (Upper Triassic, France): a Systematic Review

Author:

Debuysschere

Abstract:

The origin and first diversification of mammals in the Upper Triassic remain poorly understood, in part because many fossil discoveries are not fully studied, and in part because the material remains poor. The Saint-Nicolas-de-Port quarry (Rhaetian, France) is the second most important locality that yielded remains of Kuehneotherium, after the fissure-fillings of the Glamorganshire (Lower Jurassic, Wales). This study identifies one new species of Kuehneotherium, K. stanislavi, sp. nov., and a new genus of Kuehneotheriidae, Fluctuodon necmergor, gen. et sp. nov. For these two new species, lower and upper molars are described and the first reconstructions of the postcanine row are proposed. Comparisons with material of Kuehneotherium from other Upper Triassic sites (Syren in Luxembourg, Emborough in England, and Jameson Land in Greenland) suggest two distinct Upper Triassic specific kuehneotheriid assemblages, respectively, west and east of the London Brabant Massif. They also suggest that the extinction event during the Triassic/Jurassic transition did not have a great impact on Kuehneotherium.

Review of the Supposed Ediacaran Paleosols

Field and laboratory tests for recognition of Ediacaran paleosols

Author:

Rettallack

Abstract:

Not a single paleosol had been described from rocks of Ediacaran age until 2011, but 354 Ediacaran paleosols have been described by 20 different authors since then. Some of these newly recognized paleosols have proven controversial, so this paper reviews 20 distinct tests to determine whether a particular Ediacaran bed could be a paleosol, or not. One problem has been that Ediacaran paleosols are not precisely like modern soils because they lack root traces, a diagnostic feature of Silurian and geologically younger paleosols. The principal problem for recognition of some Ediacaran paleosols is the occurrence in them of megafossils assumed to have been marine, although most of these fossils remain problematic for both biological and ecological affinities. Not all the tests discussed here are diagnostic of paleosols, some are ranked permissive or persuasive. Permissive conditions for paleosols include ripple marks, hummocky bedding, pyritic limestones, acritarchs or thalloid fossils, low strontium isotopic ratios, high δ26Mg ratios, and red color. Persuasive tests include loessites, tsunamites, desert playa minerals, low boron content, high δ10B isotopic ratios, high carbon/sulfur ratios, and very low total/reactive iron ratios. Diagnostic tests include matrix-supported lapilli or crystal tuff parent materials, ice wedges and other cryoturbation, sepic birefringence fabrics, evaporitic sand crystals, and negative geochemical strain and mass transfer, and highly correlated δ13C and δ18O. Like other geological periods, the Ediacaran is known from a variety of marine and non-marine paleoenvironments

Orogeny on Io: how do you Make Mountains on Jupiter's Moon?


Mountains aren't the first thing that hit you when you look at images of Jupiter's innermost moon, Io. But once you absorb the fact that the moon is slathered in sulfurous lava erupted from 400 active volcanoes, you might turn your attention to scattered bumps and lumps that turn out, on closer inspection, to be Io's version of mountains.There are about 100 of them, and they don't look anything like the low lying volcanoes.

They also don't look like mountains on our home world. While we favor majestic ranges stretching from horizon to horizon, the mountains on Io are isolated peaks of great height that jut up out of nowhere. From space, they look rather like the blocky chips in the fancier kind of chocolate chip cookie.

For planetary geophysicists like William McKinnon, professor of earth and planetary science in Arts & Sciences at Washington University in St. Louis, the mountains of Io are an intriguing puzzle. By what process consistent with everything that is known about Io could these bizarre mountains have formed?

Since Io buries the evidence of its tectonic processes under a continually refreshed coating of lava (adding 5 inches a decade), the scientists have turned increasingly to computer simulations to solve the problem. In the May 16 online advance issue of Nature Geoscience, McKinnon and Michael T. Bland, a research space scientist at the USGS Astrogeology Science Center in Flagstaff, Ariz., publish a computer model that is able to make numerical mountains that look much like the jutting rock slabs on Io.

Venus was Recently Resurfaced

Mantle potential temperature estimates of basalt from the surface of Venus

Author:

Shellnutt

Abstract:

The crater density and distribution of Venus indicates the average surface age is younger (≤1 Ga) than most terrestrial planets and satellites in the Solar System. The type and rate (i.e. equilibrium, catastrophic or differential) of volcanism associated with the stagnant lid tectonic system of Venus is a first order problem that has yet to be resolved but is directly related to the thermal conditions of the mantle. The calculated primary melt composition of basalt at the Venera 14 landing site is high-Mg basalt to picrite with a mantle potential temperature estimate similar to terrestrial ambient mantle (1370 ± 70 °C). The calculated accumulated fractional melting curves indicate the olivine compositions from the melt have Mg# of 89–91. The results show that the thermal regime required to generate the primary melt composition of the Venera 14 basalt was not anomalously high (i.e. mantle-plume system) but rather consistent with a lithospheric tensional rift system. The juxtaposition of high thermal regime structures (e.g. Beta Regio) and ‘ambient’ mantle potential temperature estimates of the Venera 14 basalt suggests that the relatively young surface of Venus is the result of volcanism from a combination of thermal systems that resurfaced the planet at variable rates.

Why DARPA is Pursuing the XS-1 Spaceplane

Here’s a phrase that’s not repeated everyday in the space community:

“You’ve heard Elon’s comments … we want to go beyond that,” Brad Tousley, the head of the tactical technology office at the Defense Advanced Research Projects Agency, said May 15.

Elon, of course, is Elon Musk, the optimistic, and some say visionary, founder of SpaceX with plans of eventually colonizing Mars. After landing three first-stage rockets, Musk has said SpaceX would inspect the rockets with plans to later re-fly most of them.

Tousley oversees DARPA’s space programs, which often handles the Defense Department’s most difficult development challenges. He described the landing of first stage rockets by SpaceX and Blue Origin as “very, very impressive accomplishments.”

But during a speech at the GEOINT 2016 conference here, Tousley said the agency’s experimental spaceplane, known as XS-1, also has ambitious plans.

“We want to launch again in 24 hours,” he said.

USS Zumwalt Delivered


General Dynamics Bath Iron Works delivered the first Zumwalt-class guided missile destroyer to the Navy on Friday, Naval Sea Systems Command announced.

The delivery of the 16,000-ton Zumwalt (DDG-1000) optimized for stealth and operations close to shore follows last month’s successful acceptance trials of the ship overseen by the service’s Board of Inspection and Survey (INSURV), Navy officials told USNI News.

INSURV evaluated the ship’s hull, mechanical and engineering (HM&E) systems during the underway testing period last month.

“Zumwalt’s crew has diligently trained for months in preparation of this day and they are ready and excited to take charge of this ship on behalf of the U.S. Navy,” said Capt. James Kirk, commanding officer of Zumwalt in a statement. “These are 143 of our nation’s finest men and women who continue to honor Admiral Zumwalt’s namesake with their dedication to bringing this ship to life.”

Now that Zumwalt is delivered, the ship’s crew will move aboard and begin an about four-month training process to operate the ship ahead of the ship’s planned commissioning in Baltimore on Oct. 15.

Following commissioning, the ship will transit to San Diego to complete the combat systems activation in a post-delivery maintenance availability. The move will free up additional space in the BIW yard allowing more room for the construction of other ships at Bath.

Changing atmospheric CO2 concentration was the primary driver of early Cenozoic climate

Changing atmospheric CO2 concentration was the primary driver of early Cenozoic climate

Authors:

Anagnostou et al

Abstract:

The Early Eocene Climate Optimum (EECO, which occurred about 51 to 53 million years ago)1, was the warmest interval of the past 65 million years, with mean annual surface air temperature over ten degrees Celsius warmer than during the pre-industrial period2, 3, 4. Subsequent global cooling in the middle and late Eocene epoch, especially at high latitudes, eventually led to continental ice sheet development in Antarctica in the early Oligocene epoch (about 33.6 million years ago). However, existing estimates place atmospheric carbon dioxide (CO2) levels during the Eocene at 500–3,000 parts per million5, 6, 7, and in the absence of tighter constraints carbon–climate interactions over this interval remain uncertain. Here we use recent analytical and methodological developments8, 9, 10, 11 to generate a new high-fidelity record of CO2 concentrations using the boron isotope (δ11B) composition of well preserved planktonic foraminifera from the Tanzania Drilling Project, revising previous estimates6. Although species-level uncertainties make absolute values difficult to constrain, CO2 concentrations during the EECO were around 1,400 parts per million. The relative decline in CO2 concentration through the Eocene is more robustly constrained at about fifty per cent, with a further decline into the Oligocene12. Provided the latitudinal dependency of sea surface temperature change for a given climate forcing in the Eocene was similar to that of the late Quaternary period13, this CO2 decline was sufficient to drive the well documented high- and low-latitude cooling that occurred through the Eocene14. Once the change in global temperature between the pre-industrial period and the Eocene caused by the action of all known slow feedbacks (apart from those associated with the carbon cycle) is removed2, 3, 4, both the EECO and the late Eocene exhibit an equilibrium climate sensitivity relative to the pre-industrial period of 2.1 to 4.6 degrees Celsius per CO2 doubling (66 per cent confidence), which is similar to the canonical range (1.5 to 4.5 degrees Celsius15), indicating that a large fraction of the warmth of the early Eocene greenhouse was driven by increased CO2 concentrations, and that climate sensitivity was relatively constant throughout this period.

Ecomorphological diversifications of Mesozoic marine reptiles

Ecomorphological diversifications of Mesozoic marine reptiles: the roles of ecological opportunity and extinction

Authors:

Stubbs et al

Abstract:

Mesozoic marine ecosystems were dominated by several clades of reptiles, including sauropterygians, ichthyosaurs, crocodylomorphs, turtles, and mosasaurs, that repeatedly invaded ocean ecosystems. Previous research has shown that marine reptiles achieved great taxonomic diversity in the Middle Triassic, as they broadly diversified into many feeding modes in the aftermath of the Permo-Triassic mass extinction, but it is not known whether this initial phase of evolution was exceptional in the context of the entire Mesozoic. Here, we use a broad array of disparity, morphospace, and comparative phylogenetic analyses to test this. Metrics of ecomorphology, including functional disparity in the jaws and dentition and skull-size diversity, show that the Middle to early Late Triassic represented a time of pronounced phenotypic diversification in marine reptile evolution. Following the Late Triassic extinctions, diversity recovered, but disparity did not, and it took over 100 Myr for comparable variation to recover in the Campanian and Maastrichtian. Jurassic marine reptiles generally failed to radiate into vacated functional roles. The signatures of adaptive radiation are not seen in all marine reptile groups. Clades that diversified during the Triassic biotic recovery, the sauropterygians and ichthyosauromorphs, do show early diversifications, early high disparity, and early burst, while less support for these models is found in thalattosuchian crocodylomorphs and mosasaurs. Overall, the Triassic represented a special interval in marine reptile evolution, as a number of groups radiated into new adaptive zones.

Macroscopic (complex?) Eukaryotes From the Calymmian MesoProterozoic One Billion Years Before the Cambrian Explosion


Decimetre-scale multicellular eukaryotes from the 1.56-billion-year-old Gaoyuzhuang Formation in North China

Authors:

Zhu et al

Abstract:

Fossils of macroscopic eukaryotes are rarely older than the Ediacaran Period (635–541 million years (Myr)), and their interpretation remains controversial. Here, we report the discovery of macroscopic fossils from the 1,560-Myr-old Gaoyuzhuang Formation, Yanshan area, North China, that exhibit both large size and regular morphology. Preserved as carbonaceous compressions, the Gaoyuzhuang fossils have statistically regular linear to lanceolate shapes up to 30 cm long and nearly 8 cm wide, suggesting that the Gaoyuzhuang fossils record benthic multicellular eukaryotes of unprecedentedly large size. Syngenetic fragments showing closely packed ~10 μm cells arranged in a thick sheet further reinforce the interpretation. Comparisons with living thalloid organisms suggest that these organisms were photosynthetic, although their phylogenetic placement within the Eukarya remains uncertain. The new fossils provide the strongest evidence yet that multicellular eukaryotes with decimetric dimensions and a regular developmental program populated the marine biosphere at least a billion years before the Cambrian Explosion.

Say Hello to Transparent Wood

Wood makes for better walls than windows — most of the time.

Researchers from the University of Maryland devised a way to strip the colors and and chemicals from a block of wood to leave behind a clear, transparent material that’s stronger and more insulating than glass, and biodegrades better than plastic.

Europa may Have an Ocean Chemistry Like Earth's

The ocean of Jupiter's moon Europa could have the necessary balance of chemical energy for life, even if the moon lacks volcanic hydrothermal activity, finds a new study.

Europa is strongly believed to hide a deep ocean of salty liquid water beneath its icy shell. Whether the Jovian moon has the raw materials and chemical energy in the right proportions to support biology is a topic of intense scientific interest. The answer may hinge on whether Europa has environments where chemicals are matched in the right proportions to power biological processes. Life on Earth exploits such niches.

In the new study published in Geophysical Research Letters, a journal of the American Geophysical Union, scientists at NASA's Jet Propulsion Laboratory (JPL), Pasadena, California, compared Europa's potential for producing hydrogen and oxygen with that of Earth, through processes that do not directly involve volcanism. The balance of these two elements is a key indicator of the energy available for life. The study found that the amounts would be comparable in scale; on both worlds, oxygen production is about 10 times higher than hydrogen production.

The work draws attention to the ways that Europa's rocky interior may be much more complex and possibly Earthlike than people typically think, according to Steve Vance, a planetary scientist at JPL and lead author of the new study. "We're studying an alien ocean using methods developed to understand the movement of energy and nutrients in Earth's own systems. The cycling of oxygen and hydrogen in Europa's ocean will be a major driver for Europa's ocean chemistry and any life there, just it is on Earth."

Evidence of Mega Tsunamis on Mars

The geologic shape of what were once shorelines through Mars' northern plains convinces scientists that two large meteorites - hitting the planet millions of years apart - triggered a pair of mega-tsunamis. These gigantic waves forever scarred the Martian landscape and yielded evidence of cold, salty oceans conducive to sustaining life.

"About 3.4 billion years ago, a big meteorite impact triggered the first tsunami wave. This wave was composed of liquid water. It formed widespread backwash channels to carry the water back to the ocean," said Alberto Fairén, Cornell visiting scientist in astronomy and principal investigator at the Center of Astrobiology, Madrid.

Fairén, who with lead author Alexis Rodriguez of the Planetary Science Institute and 12 others, published their work in Scientific Reports (May 19), a publication of the journal Nature.

The scientists found evidence for another big meteorite impact, which triggered a second tsunami wave. In the millions of years between the two meteorite impacts and their associated mega-tsunamis, Mars went through frigid climate change, where water turned to ice, Fairén said: "The ocean level receded from its original shoreline to form a secondary shoreline, because the climate had become significantly colder."

The second tsunami formed rounded lobes of ice. "These lobes froze on the land as they reached their maximum extent and the ice never went back to the ocean - which implies the ocean was at least partially frozen at that time," he said. "Our paper provides very solid evidence for the existence of very cold oceans on early Mars. It is difficult to imagine Californian beaches on ancient Mars, but try to picture the Great Lakes on a particularly cold and long winter, and that could be a more accurate image of water forming seas and oceans on ancient Mars."

These icy lobes retained their well-defined boundaries and their flow-related shapes, Fairén said, suggesting the frozen ancient ocean was briny. "Cold, salty waters may offer a refuge for life in extreme environments, as the salts could help keep the water liquid. ... If life existed on Mars, these icy tsunami lobes are very good candidates to search for biosignatures," he said.

Boeing Starliner Test Article Coming Together, Unmanned Flight in 2017, First Crewed Flight in 2018


As completion nears for the prototype of Boeing’s first Starliner astronaut taxi, the aerospace firm announced a slip into 2018 for the blastoff date of the first crewed flight in order to deal with spacecraft mass, aerodynamic launch and flight software issues, a Boeing spokesperson told Universe Today.

Until this week, Boeing was aiming for a first crewed launch of the commercial Starliner capsule by late 2017, company officials had said.

The new target launch date for the first astronauts flying aboard a Boeing CST-100 Starliner “is February 2018,” Boeing spokeswoman Rebecca Regan told Universe Today.

“Until very recently we were marching toward the 2017 target date.”

US Navy Studying Placing Laser Weapons on Burke Flight III Destroyers


The officer in charge of the US Navy's (USN's) DDG 51 Arleigh Burke-class destroyer restart programme said on 17 May that the navy is examining directed energy weapons for possible inclusion on future ships.

"I can tell you we're looking intently at things like LaWS [Laser Weapon System] and the next generation of LawS, for a directed energy weapon," Captain Mark Vandroff said during a briefing at the Navy League's 2016 Sea-Air-Space symposium in National Harbor, Maryland. A technical feasibility study is ongoing, he confirmed to IHS Jane's .

Man Made Earthquakes Have Been Happening in Texas Since the 1920s

Earthquakes triggered by human activity have been happening in Texas since at least 1925, and they have been widespread throughout the state ever since, according to a new historical review of the evidence published online May 18 in Seismological Research Letters.

The earthquakes are caused by oil and gas operations, but the specific production techniques behind these quakes have differed over the decades, according to Cliff Frohlich, the study's lead author and senior research scientist and associate director at the Institute for Geophysics at the University of Texas at Austin.

Frohlich said the evidence presented in the SRL paper should lay to rest the idea that there is no substantial proof for human-caused earthquakes in Texas, as some state officials have claimed as recently as 2015.

At the same time, Frohlich said, the study doesn't single out any one or two industry practices that could be managed or avoided to stop these kinds of earthquakes from occurring. "I think we were all looking for what I call the silver bullet, supposing we can find out what kinds of practices were causing the induced earthquakes, to advise companies or regulators," he notes. "But that silver bullet isn't here."

Machairoceratops cronusi: a new Ornate Centrosaurine Ceratopsid From Campanian Cretaceous Utah


A New Centrosaurine Ceratopsid, Machairoceratops cronusi gen et sp. nov., from the Upper Sand Member of the Wahweap Formation (Middle Campanian), Southern Utah

Authors:

Lund et al

Abstract:

The Upper Cretaceous (middle-late Campanian) Wahweap Formation of southern Utah contains the oldest diagnostic evidence of ceratopsids (to date, all centrosaurines) in North America, with a number of specimens recovered from throughout a unit that spans between 81 and 77 Ma. Only a single specimen has been formally named, Diabloceratops eatoni, from the lower middle member of the formation. Machairoceratops cronusi gen. et sp. nov., a new centrosaurine ceratopsid from the upper member of the Wahweap Formation, is here described based on cranial material representing a single individual recovered from a calcareous mudstone. The specimen consists of two curved and elongate orbital horncores, a left jugal, a nearly complete, slightly deformed braincase, the left squamosal, and a mostly complete parietal ornamented by posteriorly projected, anterodorsally curved, elongate spikes on either side of a midline embayment. The fan-shaped, stepped-squamosal is diagnostic of Centrosaurinae, however, this element differs from the rectangular squamosal in Diabloceratops. Machairoceratops also differs in the possession of two anterodorsally (rather than laterally) curved epiparietal ornamentations on either side of a midline embayment that are distinguished by a posteromedially-oriented sulcus along the entire length of the epiparietal. Additionally, the parietosquamosal frill is lacking any other epiossifications along its periphery. Machairoceratops shares a triangular (rather than round) frill and spike-like epiparietal loci (p1) ornamentation with the stratigraphically lower Diabloceratops. Both parsimony and Bayesian phylogenetic analyses place Machairoceratops as an early-branching centrosaurine. However, the parsimony-based analysis provides little resolution for the position of the new taxon, placing it in an unresolved polytomy with Diabloceratops. The resultant Bayesian topology yielded better resolution, aligning Machairoceratops as the definitive sister taxon to a clade formed by Diabloceratops and Albertaceratops. Considered together, both phylogenetic methods unequivocally place Machairoceratops as an early-branching centrosaurine, and given the biostratigraphic position of Machairoceratops, these details increase the known ceratopsid diversity from both the Wahweap Formation and the southern portion of Laramidia. Finally, the unique morphology of the parietal ornamentation highlights the evolutionary disparity of frill ornamentation near the base of Centrosaurinae.

Spiclypeus shipporum: a new Ornate Chasmosaurine Ceratopsid From Campanian Cretaceous Montana


Spiclypeus shipporum gen. et sp. nov., a Boldly Audacious New Chasmosaurine Ceratopsid (Dinosauria: Ornithischia) from the Judith River Formation (Upper Cretaceous: Campanian) of Montana, USA

Authors:

Mallon et al

Abstract:

This study reports on a new ceratopsid, Spiclypeus shipporum gen et sp. nov., from the lower Coal Ridge Member of the Judith River Formation in Montana, USA, which dates to ~76 Ma (upper Campanian). The species is distinguished by rugose dorsal contacts on the premaxillae for the nasals, laterally projecting postorbital horncores, fully fused and anteriorly curled P1 and P2 epiparietals, and a posterodorsally projecting P3 epiparietal. The holotype specimen is also notable for its pathological left squamosal and humerus, which show varied signs of osteomyelitis and osteoarthritis. Although the postorbital horncores of Spiclypeus closely resemble those of the contemporaneous ‘Ceratops’, the horncores of both genera are nevertheless indistinguishable from those of some other horned dinosaurs, including Albertaceratops and Kosmoceratops; ‘Ceratops’ is therefore maintained as a nomen dubium. Cladistic analysis recovers Spiclypeus as the sister taxon to the clade Vagaceratops + Kosmoceratops, and appears transitional in the morphology of its epiparietals. The discovery of Spiclypeus adds to the poorly known dinosaur fauna of the Judith River Formation, and suggests faunal turnover within the formation.

Evidence of Predation (!!) From the Tonian NeoProterozoic

Tiny vampires in ancient seas: evidence for predation via perforation in fossils from the 780–740 million-year-old Chuar Group, Grand Canyon, USA

Author:

Porter

Abstract:

One explanation for the Early Neoproterozoic expansion of eukaryotes is the appearance of eukaryovorous predators—i.e. protists that preyed on other protists. Evidence for eukaryovory at this time, however, is indirect, based on inferences from character state reconstructions and molecular clocks, and on the presence of possible defensive structures in some protistan fossils. Here I describe 0.1–3.4 µm circular holes in seven species of organic-walled microfossils from the 780–740 million-year-old Chuar Group, Grand Canyon, Arizona, USA, that are similar to those formed today by predatory protists that perforate the walls of their prey to consume the contents inside. Although best known in the vampyrellid amoebae, this ‘vampire-like’ behaviour is widespread among eukaryotes, making it difficult to infer confidently the identity of the predator. Nonetheless, the identity of the prey is clear: some—and perhaps all—of the fossils are eukaryotes. These holes thus provide the oldest direct evidence for predation on eukaryotes. Larger circular and half-moon-shaped holes in vase-shaped microfossils from the upper part of the unit may also be the work of ‘tiny vampires’, suggesting a diversity of eukaryovorous predators lived in the ancient Chuar sea.

Israel Claims to Have Successfully Tested Iron Dome From a Ship

Israel claimed Wednesday that it successfully intercepted a test salvo of shore-launched short-range rockets with a new sea-based version of the Iron Dome.

Col. Ariel Shir, the Israel Navy’s head of combat systems development, said the live fire test was conducted two weeks ago using the Adir radar developed by Israel Aerospace Industries/Elta and the Rafael-developed Iron Dome, both of which were integrated aboard the service’s INS Lahav Sa’ar-5 corvette-class surface vessel.

“I can say all the threats shot toward our assets were targeted by the Adir radar — one of the most advanced naval radars that exists today — and interception was accomplished by Iron Dome,” Shir told reporters Wednesday.

Iron Fertilization Will NOT Work in the Pacific

Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of the ocean's carbon-capturing algae - algae need iron to grow - but a new study shows that the excess iron had little to no effect.

The results are important today, because as groups search for ways to combat climate change, some are exploring fertilizing the oceans with iron as a solution.

Dwarf Planet 2007 OR10 Much Larger Than Originally Thought

According to a team of astronomers making use of data from two powerful orbital telescopes, a dwarf planet known as 2007 OR10 orbiting in the far reaches of our solar system is significantly larger than previously believed. The results of the study makes the little-known planetoid the third largest dwarf planet behind Pluto and Eris.

Previous observations of 2007 OR10 using only infrared data from the Herschel telescope had estimated the dwarf planet to have a diameter of around 795 miles (1,280 km). However, these readings were taken without knowledge of 2007 OR10's rotational period, which is a key variable needed for astronomers to extrapolate the size of a heavenly body.

Without this key variable, the light detected by a telescope could lead to incorrect estimations of a planetoid's size, as was the case with 2007 OR10. A smaller body with a brighter surface could potentially appear larger than a darker, much larger dwarf planet.

The new research paired infrared readings collected by Herschel with visible light data harvested by the Kepler spacecraft, which was tasked with observing 2007 OR10 for a continuous period of 19 days in late 2014. The combination of the data sets allowed astronomers to deduce a number of characteristics of the distant planetoid.

China to Fly Next Generation Space Capsule in June


The top of the capsule, seen in designs and apparent development above, packs parachutes, GNSS antenna and antenna specially designed to prevent radio silence during hypersonic re-entry….

The successor to the currently-used Shenzhou spacecraft – the 11th mission of which will take two astronauts to Tiangong-2 late this year – will be made from advanced aluminium alloys in order to reduce the vessel’s weight to allow more crew and cargo.

While Shenzhou re-entry capsules return to Earth and touch down on land at Siziwang Banner in Inner Mongolia, the new capsule can also be recovered at sea. It has not thus far been stated if this capability will be tested in June.

Z-Man allows People to be Geckos on Glass

They call it “Z-Man” but only because “Spider Man” had already been taken and put under trademark, said Eugene Choi, Technology Leader for the climbing device developed by the Defense Advanced Research Projects Agency, or DARPA.

The literature described Z-Man as designed to “enable the warfighter carrying a full combat load to scale vertical walls.”

Choi said the military already had a lot of gear to help with climbing in the field, but “we didn’t have a very good way to climb those surfaces” that troops would meet in city combat, such as glass, concrete or dry wall.

Z-Man prototypes consisted of hand-held devices that stick to any surface and bear loads of more than 300 pounds. The handhelds have ropes that attach to the feet of the climber and literally allow the climber to walk up the wall.
