China Will Deploy AntiSatellite Laser in 2020

China's military is expected to deploy a laser weapon capable of destroying or damaging U.S. military satellites in low earth orbit in the next year, the Pentagon's Defense Intelligence Agency disclosed in a report on space threats.

The Chinese directed energy weapon is among an array of space warfare tools that include ground-based anti-satellite (ASAT) missiles, electronic jammers, cyber attacks, and small satellites Beijing plans to use in attacks on U.S. satellites in a future conflict.

"China likely is pursuing laser weapons to disrupt, degrade, or damage sat­ellites and their sensors and possibly already has a limited capability to employ laser systems against satellite sensors," the unclassified intelligence report said.

"China likely will field a ground-based laser weapon that can counter low-orbit space-based sensors by 2020, and by the mid-to-late 2020s, it may field higher power systems that extend the threat to the structures of non-optical satellites."

It was the first time a U.S. intelligence agency disclosed details of the ASAT laser deployment plans.

NASA Considering Buying More Soyuz Seats with SpaceX, Boeing Capsule Delays

Amid uncertainty about the Commercial Crew schedule, NASA has issued a pre-solitication procurement notice to secure additional rides with the Russians for its astronauts.

“NASA is considering contracting with the State Space Corporation ‘Roscosmos’ for these services on a sole source basis for two (2) Soyuz seats and associated services to the International Space Station (ISS) on the Russian Soyuz spacecraft vehicle. This transportation would be for one crewmember in the Fall of 2019 and one crew member in the Spring of 2020,” the agency said in the Feb. 13 notice.

JP Morgan Chase Announces its own Cryptocurrency

J.P. Morgan Chase CEO Jamie Dimon called bitcoin a fraud in September 2017 and said, “You can’t have a business where people can invent a currency out of thin air and think that people who are buying it are really smart,” By January 2018 he had walked the remarks back but said he still was “not interested that much in the subject at all.” In February 2018, J.P. Morgan called cryptocurrencies “risk factors” to its business, something it never previously said.

And now J.P. Morgan (JPM, +0.19%) has become the first bank to offer its own cryptocurrency, CNBC reported. But don’t expect it to become an investment vehicle—at least for now. The cryptocurrency, called “JPM Coin,” is intended for the bank’s wholesale payments business that moves $6 trillion around the world daily.

Russia Claims Will Develop Two New INF Violating Missiles by 2021 (hint: already were)

Russia will race to develop two new land-based missile launch systems before 2021 to respond to Washington’s planned exit from a landmark nuclear arms control pact, it said on Tuesday.

President Vladimir Putin said at the weekend that Russia had suspended the Cold War-era Intermediate-range Nuclear Forces Treaty (INF), which bans both nations from stationing short- and intermediate-range land-based missiles in Europe.


Russia will formally exit the INF treaty in six months.  Some naively believe Russia might opt for negotiation instead of new weapons.  Russia's reply above ought to make their position very, very clear: do as I say, not as I do!

Let's be blunt.

Russia cannot magically develop new weapons in 2 years.  They must have been working on them for years.  By saying the above, the Russians are admitting they were violating the INF blatantly and not just with the single system the US claimed they were breaking the treaty with.

Oh!  The Russians are looking for a few useful idiots!

The Russians appear to have over 64 of the INF violating, ground launched 9M729 cruise missiles.

China is Going to Attempt More than 30 Launches in 2019

The main contractor for the Chinese space program is planning more than 30 launches in 2019, with major missions including the crucial return-to-flight of the heavy-lift Long March 5 rocket in July.

The China Aerospace Science and Technology Corporation (CASC), announced Jan. 29 that it would aim to loft more than 50 spacecraft on 30-plus launches this year.

Among these will be the third launch on the Long March 5, a 5-meter-diameter, 57-meter-tall heavy-lift launch vehicle which failed in its second flight in July 2017, delaying the Chang’e-5 lunar sample return mission and the construction of the Chinese Space Station.

China Built a Satellite Ground Station in Argentina, but Reneged on Agreements After

When China built a military-run space station in Argentina’s Patagonian region it promised to include a visitors’ center to explain the purpose of its powerful 16-story antenna.

The center is now built - behind the 8-foot barbed wire fence that surrounds the entire space station compound. Visits are by appointment only.

Shrouded in secrecy, the compound has stirred unease among local residents, fueled conspiracy theories and sparked concerns in the Trump administration about its true purpose, according to interviews with dozens of residents, current and former Argentine government officials, U.S. officials, satellite and astronomy specialists and legal experts.

The station’s stated aim is peaceful space observation and exploration and, according to Chinese media, it played a key role in China’s landing of a spacecraft on the dark side of the moon in January.

But the remote 200-hectare compound operates with littleoversight by the Argentine authorities, according to hundreds of pages of Argentine government documents obtained by Reuters and reviewed by international law experts.

Russia's Angara 5 Rocket has a Serious Design Flaw

Scientists have discovered a defect in the engines of Russia’s new flagship heavy lift space rocket that could destroy it in flight, an apparent setback to a project President Vladimir Putin has said is vital for national security.

The Angara A5, which was test-launched in 2014, is being developed to replace the Proton M as Russia’s heavy lift rocket, capable of carrying payloads bigger than 20 tonnes into orbit. A launch pad for the new rocket is due to open in 2021.

In July, Putin said the Angara A5 had “huge significance” for the country’s defense and called on space agency Roscosmos to work more actively on it and to meet all its deadlines.

The issue with the Angara A5 was brought to attention by scientists at rocket engine manufacturer Energomash in a paper ahead of a space conference later this month.

The paper, reported by RIA news agency on Friday and published online, said the engines of the Angara A5 could produce low frequency oscillations that could ultimately destroy the rocket.

A special valve had been fitted to mitigate the issue, but in some cases the oscillations continued, it said. Energomash did not immediately reply to a request for comment.

Russia Tested its Burevestnik Their Nuclear Powered Cruise Missile, on January 29, 2019

Russia conducted a partially successful test of its developmental nuclear-powered cruise missile, the Burevestnik, on January 29, 2019, according to U.S. government sources with knowledge of Russia’s weapons programs who spoke to the The Diplomat. The test took place at Russia’s Kapustin Yar missile test range and is the thirteenth to date involving the missile.

The test marks the first involving the Burevestnik in nearly one year. The missile had not been tested since February 2018. According to one source, U.S. intelligence assesses that Russia’s development efforts on the missile continues. The United States intelligence community internally calls the missile the KY30 or the SSC-X-9 SKYFALL.

Pondering the Precambrian #26

Proterozoic:

NeoProterozoic:

The Earth's magnetic field was 10% of what it is today during the Ediacaran and the Earth's solid core may date from that period.

Evidence from Murmansk supports the weak magnetic field hypothesis during the Proterozoic.

Trace fossils from the Ediacaran have been found in Brittany, France.

Ediacaran environmental changes are recorded in Brazil.

The iodine content of the the Doushanto deposits of the Ediacaran.

Microorganisms are the source of organic carbon found in Sichuan from the Ediacaran into the Cambrian. 

It appears Cloudina and other tubular organisms from the terminal Ediacaran appear to have reproduced asexually.

There is evidence of hydrothermal activity altering various deposits during the Ediacaran.

Evidence of the breakup of Rodinia to the accretion of Gondwana in the Ediacaran from Paraguay.

A new biomarker has been found from the Cryogenian that hints at how complex life evolved after the Snowball Earth.

There was a deep marine organic reservoir in the Cryogenian.

Starting in the Cryogenian until the start of the Carboniferous, there was significant lack of impacts.  There might be evidence of the Snowball Earth via a global wiping of the impact craters from before that point, too.

Could the Great Noncomformity be due to the Snowball Earth?

The Great Noncomformity represents a 200to 300 million year gap in the depositional history of the world according to evidence from the North China Craton.

There are graphite particles in Cryogenian deposits of Nantuo.

Manganese ore deposits in South China were formed in the interglacial between the Sturtian and Marinoan glacials by microbial activity.

Is hydrothermal activity from the Tonian of the Western Australian Craton evidence of the breakup of Rodinia?

Mesoproterozoic:

Eukaryotes diversified earlier than previously thought, starting in the Ectasian.

Paleoproterozoic:

There was a 30 degree shift in the mafic dyke swarms during the Paleoproterozoic.

The surface conditions of at the start of the Great Oxygenation Event were anoxic.

There is evidence from the Yangtze Block that contradicts the hypothesis that there was a shutdown of plate tectonics during the PaleoProterozoic.

Archean:

A coupled crust/mantle formed before 2.5 billion years ago.

Evidence from the MesoArchean to the Paleoproterozoic of Norway show how the continents were built up.

More evidence of episodic crust growth starting in the MesoArchean.

There may be EoArchean deposits in the North China craton.

Sarmatia, Pilbara, and Kaapvaal Cratons were all part of the single supercontinent Vaalbara.

There's no evidence of pre 3.95 billion year old fossils.

Hadean:

Did the impact with Theia provide the volatiles the Earth needed for life?

Did asteroid impacts have a central role in the formation of the original continents?

META:

There is a 600 million year superocean cycle modulating a longer supercontinent.

Could sulfur dioxide have helped with the start of prebiotic carbohydrates?

There are biochemical hints that the last common universal ancestor - the last life form from which everything alive is descended - was not a hyperthermophile.

Reconstruction the Last Eukaryote Common Ancestor's genome to understand the evolution from the First Eukaryote Common Ancestor to the LECA.

Chunks of RNA can be formed prebioticly.

Studying algae suggest eukaryotes have received numerous DNA additions from bacteria.

Mike Griffin Gets his own Pet Space Agency

Acting Defense Secretary Patrick Shanahan is moving to set up a new Pentagon agency to oversee the development of military space technology. The Space Development Agency will be under the “authority, direction and control” of Undersecretary of Defense for Research and Engineering Michael Griffin, Shanahan wrote in a memo.

Shanahan has directed Griffin to submit a plan by March 1 to stand up the Space Development Agency no later than March 29, according to a Jan. 19 memo titled “Implementation Guidance for the Establishment of the Space Development Agency.” The existence of the memo was first reported Wednesday by the publication Inside Defense. A copy of the memo was reviewed by SpaceNews.

While the Space Development Agency would be under Griffin, Shanahan’s memo takes into account the possibility that the agency could in the future be moved into the Space Force if the new branch comes to fruition. In his plan, Griffin has to “address the eventual transition of SDA to the U.S. Space Force after approved by Congress,” the memo said.
