China is Building 2 Molten Salt Thorium Reactors

The cash is to develop two “molten salt” reactors in the Gobi Desert in northern China. 
Researchers hope that if they can solve a number of technical problems the reactors will lead to a range of applications, including nuclear-powered warships and drones.
The technology, in theory, can create more heat and power than existing forms of nuclear reactors that use uranium, while producing only one thousandth of the radioactive waste. 
It also has the advantage for China of using thorium as its main fuel. China has some of the world’s largest reserves of the metal.

Stealth Saga #70

Su-57:

The F-35 hater team is now hating on the Su-57.

The Su-57 will start production in 2018 (supposedly) with 12 'pre-production' aircraft delivered in 2019.

The Su-57 is making progress on the engine and other development milestones, but concerns remain.

"New" Russian VTOL Fighter:

Russia claims it is working on the replacement of the MiG-29 and Su-33 with a VTOL fighter.  That would mean the LMFS is definitely dead instead of almost certainly.

J-20 & J-31:

A report on the J-20 updates the capabilities.

A report states future Chinese aircraft carriers will have the two 5th gen fighters aboard.

TF-X:

Turkey has released the technical specifications on the TF-X.

MAGMA:


The Brits are testing out a drone without control surfaces.  Instead, it uses airflow to control direction.


Tornado Replacement:

The Luftwaffe might prefer the F-35, but the German MoD prefers the Eurofighter.

CF-18 Replacement:

Canada is starting its replacement procurement for the CF-18.  The F-35 might be a contender.

Sixth Generation Fighter:

Directed energy weapons are finally gearing up for deployment.

F-22:

The Russians are claiming an F-22 interfered with an attack run by Su-25s but was "chased away" by an Su-35.

Could the reason the Su-35s and F-22s be shadow boxing is because both sides are trying to gather intel on the other's capabilities?

An F-22 damaged during touch and goes six years ago will be fixed soon.

UTC received an almost seven billion dollar contract for maintaining the F119 engines on the F-22.

F-35:

The F-35 is going to get a deep dive review on its costs.

66 F-35s were delivered this year.

Is there a change coming for testing on the F-35s?

F-35 weapon accuracy testing is complete.

The USAF claims to no longer need its A-10 maintenance crews to work on the F-35A.

The 115th and 187th Air National Guard Fighter Wings are getting upgraded to the F-35A.

F-35C aviators qualified on the Lincoln.

Britain is not happy about the lack of transparency for the F-35 program.

More on Israel's declaration of the F-35I being operational.

Poland has launched its Harpia fighter procurement and the F-35 is a contender.

Russian military observers went to Norway's base where its first F-35s are.

South Korea is reportedly buying 20 more F-35s.

META:

F/A-18s spotted an unknown aircraft and tracked it on their FLIR.

Fictional Aircraft:

A real US Naval Academy professor did a presentation on the stealthiness of cinematic version of the fictional MiG-31 Firefox.

How the US Says Russia Violated the INF Treaty

The word is that U.S. administration has finally identified the cruise missile that it suspects to violate the INF Treaty. In his remarks at the Wilson Center, Christopher Ford of the National Security Council said that the missile is known in Russia as 9M729. This was the first time the Russian name of the missile, designated in the United States as SSC-8, was announced officially. But, of course, someone leaked it to Jeffrey Lewis back in 2015, so it's not really news. I had my doubts about the 9M729 theory, but if that's what the U.S. administration builds its claim on, I am not in a position to argue.

Pondering the Precambrian #7

Proterozoic:

NeoProterzoic:

The Tarim Craton may have been connected to the North India Block rather than Australia within the supercontinent of Rodinia during the Tonian.

Has evidence of mountain building during the Tonian been found in Scotland?

The Tonian/Cryogenian transition seems to have been located in Svalbard.

How complete is the evidence of glaciations during the Cryogenian in Scotland?

How oxygenated was the ocean between the Snowball Earth episodes?

Caution with carbon-13 shifts are urged in Cryogenian deposits as they are deposit dependent.

Evidence of hydrothermal modification of a dolostone during the Marinoan Glaciations.

Was there a delayed oxygenation of the oceans from the Cryogenian to the Ediacaran?

Evidence from Mongolia's 540 million year old Khesen formation documents the rise of animals.

Evidence that Ediacaran Parvancorina was motile and could sense benthic currents.

Were there constant anoxic bottom waters during the Ediacaran?

Cyanobacterial-algal crusts have been found from Ediacaran paleosols.

MesoProterozoic:

Cyanobacterial microfossils are examined from Calymmian China.

Were tellurium and selenium weathered from sandstones into the Mesoproterozoic oceans?

PaleoProterozoic:

Biosignatures have been found for eukaryotes from Statherian China.

There is evidence of an impact in India during the Siderian.

Was there a subduction cessation during the Siderian in China?

More evidence of warm subduction during the Orosirian from Cameroon.

Was the Great Oxygenation Event really an abiotic process?!

There appears to have been gradual oxygenation in the oceans (in some cases) just prior to the GOE.

A large igneous province is detected from India from the Rhyacian.

Was the early biosphere nutrient limited?

Archean:

Evidence from China, specifically the North China Craton, about the composition of NeoArchean sea water.

Inland lakes appear to have fostered the diversification of microbial life during the MesoArchean.

The oldest known paleosols (fossil soil) date from the PaleoArchean (3.46 billion years ago) and originate in Australia and may have formed from sulfuric acid weathering.

Could there be a problem with the cherts being used from the PaleoArchean to claim microbial life?

Or is there a definitive example of fossil life from the PaleoArchean?  Does that mean life is common in the universe?

Is some of Earth's magma ocean preserved in PaleoArchean rock?

META:

Exploring the Precambrian lithosphere of Zambia and Malawi.

The effect of paleoseawater chemistry on hydrothermal ridges.

Origin of Life:

The origin and diversification of the endosymbiont known as the mitochondria.

A new lineage of eukaryotes has given information on mitochondrial genome reduction.

WISE & NEOWISE Cannot Find Planet Nine

A 3pi Search for Planet Nine at 3.4 microns with WISE and NEOWISE

Authors:


Meisner et al

Abstract:
The recent 'Planet Nine' hypothesis has led to many observational and archival searches for this giant planet proposed to orbit the Sun at hundreds of astronomical units. While trans-Neptunian object searches are typically conducted in the optical, models suggest Planet Nine could be self-luminous and potentially bright enough at ~3-5 microns to be detected by the Wide-field Infrared Survey Explorer (WISE). We have previously demonstrated a Planet Nine search methodology based on time-resolved WISE coadds, allowing us to detect moving objects much fainter than would be possible using single-frame extractions. In the present work, we extend our 3.4 micron (W1) search to cover more than three quarters of the sky and incorporate four years of WISE observations spanning a seven year time period. This represents the deepest and widest-area WISE search for Planet Nine to date. We characterize the spatial variation of our survey's sensitivity and rule out the presence of Planet Nine in the parameter space searched at W1 less than 16.7 in high Galactic latitude regions (90% completeness).

India Preparing for March 2018 Chandrayaan-2 Lunar Mission

The launch of the next Moon mission could be just four months away. India plans to return to the Moon in a big way with the ambitious Chandrayaan-2, which includes an orbiter, lander, and a small rover. If it all succeeds, it will be India's first soft landing on another world, and only the second such landing since the end of the Apollo and Luna era. For India, landing success would be "a stepping stone for future exploration missions to other planets," according to Indian Space Research Organisation Satellite Centre (ISAC) director M. Annadurai.

Europe Wants its own X-37B, called the Space Rider

Space Rider is a re-entry vehicle, the evolution of the IXV (Intermediate Experimental Vehicle, launched by Vega in February 2015), capable of ‘navigating’ up to 2 months in low Earth orbit before returning to earth. Re-entry enables the recovery of all the useful load that can be analysed, and the vehicle to be reused for a new mission. The contract signed by ESA with Avio and TAS-I (Thales Alenia Space Italia) is worth a total of €36.7 million for the development of the Space Rider system, consisting of two modules: AOM (Avum Orbital Module) and RM (Re-entry Module). Avio will handle the development of AOM, a specific version of AVUM (fourth stage of the VEGA C) capable of supplying power and services for controlling the vehicle’s re-entry attitude during the orbital stage.

Paleolithic Papers #17

Genus Homo:

The brains of modern humans are different than other primates in particular ways.

Modern Humans (H. sapiens):

Ancient DNA from South Africa pushes back the origins of modern humans.

How did ancient humans organize themselves?  Check their genomes.

Did the first Americans come via the Kelp Highway?  More evidence.

Ancient mitochondrial DNA studies have shown three different groups swept into Labrador and Newfoundland at different times.

Hobbits (H. floresiensis):

How the Hobbit, LB1, was found.

Did Hobbits eat rats?

Denisovans:

John Hawks disagrees when the Denisovans and Neandertals split.

Neandertals (H. neanderthalensis):

New wrist bones from the Neandertals of El Sidron, Spain have been found and studied.

The Mousterian Neandertals of China are discussed.

A high coverage DNA Neandertal genome has been recovered from Vindijia, Croatia.

The interbreeding between modern humans and Neandertals reintroduced older, lost DNA from ancient, older hominins to the modern human genome.

The interaction between Neandertals and modern humans has been modeled.

A paper suggested modern humans replaced Neandertals through immigration.  A response has been posted.

H. heidelbergensis:

Did the sinuses of H. heidelbergensis have a special role or placement

H. naledi:

Reviewing the September excavations at the Rising Star Caves.

An H. naledi pelvis is examined and found to have characteristics of Homo and Australopithecus pelvises.

Genus Paranthropus:

P. robustus:

Isotopic analysis of P robustus teeth show the environments and even movements of individuals lived in.

META:

Crocodiles may make similar marks on bones when feeding like those interpreted to be done by stone tools and flakes used for butchery by hominins.

The jaws of hominins and their variation give important clues as to whether or not they belong to a specific species.

There are deep concerns some of the fossils from Europe of hominins were stolen and used in a study.  Even the journal has grown concerned.

Stone tools from late Oldowon from the Olduvai are investigated with new digs.

Pounding tools from the Oldowon to Acheulen transition are examined as well.

SpaceX Will Seek US Government Money for the BFR/BFS Rocket

The president of SpaceX said she expects the company would receive additional funding from the U.S. government to support the development of its large reusable launch system.

Speaking at the NewSpace Europe conference here Nov. 16, Gwynne Shotwell noted that SpaceX is already receiving funding from the U.S. Air Force supporting the development of Raptor, the engine that will power the vehicle known as BFR, or Big Falcon Rocket, and the reusable spacecraft known as BFS or Big Falcon Spaceship.

“I do anticipate that there is residual capability of that system that the government will be interested in,” she said. “I do see that we would likely get some funding from the government for BFR and BFS.” She added, though, that work on the vehicles was not contingent on receiving government funding.

One avenue for doing so would be through the U.S. Air Force’s Launch Services Agreement competition, which plans to provide several awards to companies to help fund development of prototype launch systems, though initial test flights, to end U.S. reliance on the Atlas 5 and its Russian-manufactured RD-180 engine. Proposals for the competition are due to the Air Force Nov. 20.
