NASA and Australia sign extension of space-tracking agreement

8:39 am

NASA and Australia have signed an extension of the treaty that allowed for the construction and operation of antennas in Australia used by NASA’s Deep Space Network.

Australia’s ambassador to the US, Joe Hockey, signed the Space Tracking Treaty on behalf of Australia, with the acting administrator of NASA, Robert Lightfoot, signing on behalf of the US, at a ceremony at the Australian Embassy in Washington DC.

The treaty covers civil space facilities owned by NASA and located within Australia, including the Canberra Deep Space Communication Complex at Tidbinbilla, as well as facilities in Western Australia and the Northern Territory.

That the treaty signing was turned into a photo-op, something that previous signings did not require, suggests to me that Australia’s politicians are planning bigger things for their future space program.

Thirty mile cave on the Moon?

8:34 am

A new analysis of data from Japan’s Kaguya lunar orbiter suggests that one of the cave pits it found could be an entrance to a lava tube 30 miles long.

In 2009, the Kaguya probe found a large shaft with an opening about 50 meters in diameter in the Marius Hills area. The shaft descends about 50 meters beneath the surface.

The JAXA team analyzed data obtained from a lunar radar sounder on the probe that indicated an underground structure extended west from the shaft. The study confirmed that the cavern, likely created by volcanic activity, has not collapsed, and there is the possibility of ice or water existing in rocks within the cave, the team said.

Do a search on Behind the Black using the search terms “cave” and “moon” and you will see many images of this pit, taken by Lunar Reconnaissance Orbiter as a follow-up to the Kaguya mission.

Turkey will establish space agency this year

8:26 am

The new colonial movement: According to one Turkish official, Turkey is aiming to establish its own space agency within a year in order to better coordinate its aerospace effort.

Arslan also said that once established, the Turkish space agency shall oversee all Turkish satellite manufacturing and needs, the development of Turkey’s own indigenous space launch capability and launch centre, all other aerospace requirements, and even a human spaceflight programme.

Like many of these third world space efforts, it is the country itself that is running the space program, not private companies. While the competition between these different countries (and the private American companies) will fuel the growth of the industry and the establishment of space colonies, in the long run this is not the best way to do things. It would be far better to establish policies that encourage private, competing, and independent companies within each of these third world countries. In that way, they will eventually have a larger economy and can better compete on the open market.

During its landing in April a manned Soyuz capsule became partially depressurized

7:20 pm

During its landing in April a Soyuz capsule carrying three astronauts returning from ISS became partially depressurized at about five miles altitude.

The partial loss of pressure did not put the crew in jeopardy, Stafford said. A valve normally opens once the capsule descends to an altitude of five kilometers to allow outside air into the capsule. The crewmembers were also wearing pressure suits, as is standard procedure on Soyuz landings.

The incident occurred when a buckle from the parachute system hit a welding seam in the capsule as the parachute deployed.

There is a reason the Russians require astronauts to wear pressure suits while in a Soyuz capsule. During the return to Earth in 1971 of three cosmonauts from the first Russian space station, Salyut 1, the capsule depressurized and the three men died of suffocation.

Bigelow and ULA propose lunar station

7:13 pm

Capitalism in space: Bigelow, builders of expandable space station modules, and ULA, building of rockets, have jointly proposed building an inexpensive lunar space station for NASA, to be launched by 2022.

The announcement build upon existing work between the two companies to study launching B330 modules, originally on the Atlas 5, Bigelow Aerospace President Robert Bigelow said in an Oct. 17 interview. He said his company decided to shift to the Vulcan vehicle and then build upon its capabilities, such as the ACES upper stage that is intended to also serve as a refuelable space tug. “There is synchronicity between what ULA has in the way of capabilities and what we’re doing,” Bigelow said. “We decided to collaborate and prepare a proposal that the White House and NASA could accept as part of an overall space plan.”

Bigelow emphasized he saw this proposal as a public-private partnership. He estimated NASA’s share of the costs to be $2.3 billion, in addition to the “hundreds of millions” being spent by both Bigelow Aerospace and ULA. “It’s executable within four years of receiving funding and NASA giving us the word,” he said.

The lunar depot would be available for both NASA and commercial uses, according to Bigelow. It could be visited by NASA Orion spacecraft launched by the Space Launch System, but he said it’s possible other spacecraft, like a version of SpaceX’s Dragon spacecraft, could also provide transportation to and from the facility.

Bigelow also went out of his way to say that this proposal was not meant to replace NASA’s proposed Deep Space Gateway, also a lunar space station, but as a quicker and cheaper supplement that could be launched and put into service while the gateway was being built.

In other words, Bigelow wishes to be to the Deep Space Gateway what SpaceX has been to SLS/Orion, the real thing while Congress continues to pour money into a parallel boondoggle that never goes anywhere.

Japanese metal manufacturer faked specifications to hundreds of companies

2:55 pm

Holy moly! Kobe Steel, a major Japanese supplier of steel and other metals worldwide, has admitted that it faked the specifications to metals shipped to hundreds of companies over the past decade.

Last week, Kobe Steel admitted that staff fudged reports on the strength and durability of products requested by its clients—including those from the airline industry, cars, space rockets, and Japan’s bullet trains. The company estimated that four percent of aluminum and copper products shipped from September 2016 to August 2017 were falsely labelled, Automotive News reported.

But on Friday, the company’s CEO, Hiroya Kawasaki, revealed the scandal has impacted about 500 companies—doubling the initial count—and now includes steel products, too. The practice of falsely labeling data to meet customer’s specifications could date back more than 10 years, according to the Financial Times.

For rockets the concern is less serious as they generally are not built for a long lifespan, but for airplanes and cars this news could be devastating, requiring major rebuilds on many operating vehicles.

Astronomers reduce estimate of still undiscovered dangerous asteroids

11:49 am

Astronomers have now reduced [pdf] their estimate of the number of still undiscovered dangerous Near Earth Asteroids (NEAs) that could impact the Earth from 100 to less than 40.

Observers have been cataloging potentially hazardous asteroids for decades. Based on the number of finds, the area of sky explored, and the limiting brightness our telescopes and cameras can reach, researchers can estimate what fraction of the NEA population has been detected so far and how many more objects lurk undiscovered. Harris has published numerous such estimates over the years. Recently he realized that his estimates have been plagued by a seemingly innocuous but nonetheless consequential round-off error. Once corrected, the estimated number of large (diameter > 1 kilometer) NEAs remaining to be discovered decreases from more than 100 to less than 40.

To put it mildly, there is a lot of uncertainty here. This also reminds me of the cavers’ joke question: “How many miles of unexplored passages does this cave have?”

Nearby asteroid orbits both the Earth and the Sun

11:42 am

Worlds without end: Astronomers have determined that a recently discovered object with a weird solar orbit that also has it loop around the Earth each year is an asteroid, not space junk.

The asteroid is dubbed 2016 HO3. What is most interesting about this story to me however was this tidbit:

“Of the near-Earth objects we know of, these types of objects would be the easiest to reach, so they could potentially make suitable targets for exploration,” said Veillet, director of the LBT Observatory. “With its binocular arrangement of two 8.4-meter mirrors, coupled with a very efficient pair of imagers and spectrographs like MODS, LBT is ideally suited to the characterization of these Earth’s companions.”

I am looking for a library to donate my space history files

11:27 am

I am in the process of updating my will, and in the process I am searching for a library or university or archive that would be an appropriate place to leave my space history archives, collected during the past two and a half decades. This archive includes recordings of numerous interviews with Russian and American astronauts and engineers as well as numerous scientists. It also documents quite thoroughly the first half century of the space age.

I had considered giving this archive to the four year university here in Tucson, but it appears they really don’t want it. My last conversation with the head of their special collections was quite hostile, making me wonder if he might have glanced at my webpage and was triggered by it.

If someone has a suggestion, please comment here or email me. My main desire is that this collection should stay intact. I also desire that whichever university or library accepts it also agree to this clause:

It is my request however that these space materials, which cover the history of the first half century of space exploration by someone who witnessed it and thus will be of special interest to future residents not living on Earth, shall be transferred to the first university established on a world other than Earth that is willing to cover the cost for that transfer. Should such transfer occur, the [Earth-bound university/archive] will have the right to retain copies of all materials.

Russian bribes funneled to Clinton foundation in 2009

9:55 am

Some real Russian collusion finally found! FBI investigations in 2010 found evidence of numerous Russian bribes that funneled millions to the Clinton foundation in 2009, just prior to Hillary Clinton’s decision to hand over control of a significant portion of the U.S. uranium industry to Russia.

[The FBI] obtained an eyewitness account — backed by documents — indicating Russian nuclear officials had routed millions of dollars to the U.S. designed to benefit former President Bill Clinton’s charitable foundation during the time Secretary of State Hillary Clinton served on a government body that provided a favorable decision to Moscow, sources told The Hill.

It also appears that the Obama administration sat on this evidence for four years, and then worked out plea deals for those involved that managed to hide the bribery from pubic scrutiny.

In fact, they buried the probe even after indicting some Russian principals in the operation. They only announced in 2015 that they had reached plea deals in a case involving money laundering, saying nothing about bribery, extortion, or the intent to corrupt the US nuclear industry. That information was so compartmentalized that even the FBI’s top criminal-investigation officer had no idea of the extent of the case, and no one in Congress was ever briefed on the national security concerns raised in the case. In fact, House Intelligence chair Mike Rogers claimed to the Hill that no one ever mentioned the case at all to him, despite already-extant concerns over the Uranium One deal on Capitol Hill.

Don’t expect the mainstream press, partisan Democrats all, to report on this.
