Russia to build new satellite communications cluster

10:06 am

The competition heats up: The Putin government’s newly released draft plan for Russia’s space industry includes the development of a new communications satellite constellation.

In addition to encrypted mobile communications, the Ellips satellites will support air-traffic control and traditional fixed communications. Reflecting its dual (civilian and military) application, the Ellips project would be funded jointly by the Russian space agency, Roskosmos, and by the Russian Ministry of Defense at a price tag of 65.6 billion rubles to develop and deploy the constellation.

The article then goes on to detail at length the problems the Russian communications satellite industry has had for the past two decades, including their inability to build satellites that will last in orbit as long as their competitors.

Another look at why ULA’s CEO stepped down

9:52 am

Why did ULA’s CEO step down, and did SpaceX or the Atlas 5’s dependence on Russian engines play a part?

Very worthwhile reading, as it suggests that not only is the competition from SpaceX a major factor, so was ULA’s effort to monopolize the military launch industry as well as monopolize its access to the Russian engines, denying their use by Orbital Sciences.

And to this I say, thank god for competition. It always shakes things up in a good way.

Private lunar lander completes test landing

9:40 am

The competition heats up: One of the competitors in the Google Lunar X-Prize has successfully completed its first landing test, on Earth, of its lander.

The article does not really provide a lot of information about the test itself, spending most of its copy describing what the test was supposed to do. Still, they did complete it successfully, which means they will now revise, rebuild, and retest.

Worldview-3 in orbit

9:30 am

The competition heats up: Worldview-3, launched yesterday, has been successfully activated and can now provide commercial and private customers images of the Earth with resolution comparable to military intelligence satellites.

The sensor package on WorldView-3 will be able to image objects with a ground sample distance of 31 cm (12 in.). “So we can tell you if it’s a truck, SUV or a regular car,” says Kumar Navulur, director of next-generation products at DigitalGlobe. “If there’s a high contrast we can identify features of fine scale,” he adds, giving examples of markings in a parking lot or “a tomato plant in a backyard in Asia.”

Obviously, this has both good and bad possibilities. Nonetheless, its availability increases the value of the space-based industry.

Maps showing the territories of the Kurds and the Islamic State

9:05 pm

Since I think it useful to have a rough geographical understanding of the situation, I have been digging around to find some maps that will outline the territories controlled by the both the Kurds and the Islamic State (also known as the Islamic State of Iraq and Syria [ISIS]), including the areas of dispute. This link provides the best selection I’ve found so far.

Based on these maps, I wonder when ISIS will start moving into next door Iran, as its western regions are adjacent to their present holdings.

The flight of gifted engineers from NASA

5:43 pm

Rather than work in NASA, the best young engineers today are increasingly heading to get jobs at private companies like SpaceX and XCOR.

It is a long article, worth reading in its entirety, but this quote will give the essence:

As a NASA engineering co-op student at Johnson Space Center, Hoffman trained in various divisions of the federal space agency to sign on eventually as a civil servant. She graduated from college this year after receiving a generous offer from NASA, doubly prestigious considering the substantial reductions in force hitting Johnson Space Center in recent months. She did have every intention of joining that force — had actually accepted the offer, in fact — when she received an invitation to visit a friend at his new job with rising commercial launch company SpaceX.

Hoffman took him up on the offer, flying out to Los Angeles in the spring for a private tour. Driving up to the SpaceX headquarters, she was struck by how unassuming it was, how small compared to NASA, how plain on the outside and rather like a warehouse.

As she walked through the complex, she was also surprised to find open work areas where NASA would have had endless hallways, offices and desks. Hoffman described SpaceX as resembling a giant workshop, a hive of activity in which employees stood working on nitty-gritty mechanical and electrical engineering. Everything in the shop was bound for space or was related to space. No one sat around talking to friends in the morning, “another level from what you see at NASA,” she said. “They’re very purpose-driven. It looked like every project was getting the attention it deserved.”

Seeing SpaceX in production forced Hoffman to acknowledge NASA might not be the best fit for her. The tour reminded her of the many mentors who had gone into the commercial sector of the space industry in search of better pay and more say in the direction their employers take. She thought back to the attrition she saw firsthand at Johnson Space Center and how understaffed divisions struggled to maintain operations.

At NASA young engineers find that they spend a lot of time with bureaucracy, the pace is slow, their projects often get canceled or delayed, and the creative job satisfaction is poor. At private companies like SpaceX, things are getting built now. With that choice, no wonder the decision to go private is increasingly easy.

NASA headquarters staff votes to unionize.

4:56 pm

NASA’s bureaucracy marches on: The staff at NASA headquarters today voted to unionize.

“This successful vote will allow us to work with management to improve working conditions for NASA support and administrative staff here at NASA headquarters, thereby improving operations, saving money, and retaining an engaged and professional workforce,” said Tifarah Thomas, a program specialist within NASA’s Office of the Chief Health & Medical Officer. Professional support specialists at NASA headquarters include budget analysts, policy analysts, administrative specialists, secretaries, and others.

NHPA currently represents nearly 200 engineers and scientists at NASA in Washington. The combined unit, including the professional support specialists who voted today for IFPTE representation, will now represent more than 500 workers at the headquarters of America’s space agency. IFPTE also represents engineers and scientists at NASA labs and research facilities from coast-to-coast.

Anyone with the slightest objectivity knows that the working conditions for federal employees in Washington is glorious, with pay about double what everyone else in the country makes and benefits far exceeding even the best private packages. In addition, the hours are great and just slightly longer than what my generation would have called bankers’ hours. Moreover, if I can be blunt, these engineers are mostly paper pushers. They are not the one’s designing and building anything that might fly in space. Their only reason to unionize now is because they see a threat to their cushy jobs with the advent of private space and are organizing to secure their unneeded positions.

It ain’t gravity holding this asteroid together

1:14 pm

Astronomers have discovered that near Earth asteroid 1950DA is spinning so fast that gravity can’t hold it together. Instead, it is kept whole by cohesive forces called van der Waals forces, predicted but never detected before on an asteroid.

This is the coolest factoid from the article, however:

“We found that 1950 DA is rotating faster than the breakup limit for its density,” said Rozitis. “So if just gravity were holding this rubble pile together, as is generally assumed, it would fly apart. Therefore, interparticle cohesive forces must be holding it together.”

In fact, the rotation is so fast that at its equator, 1950 DA effectively experiences negative gravity. If an astronaut were to attempt to stand on this surface, he or she would fly off into space unless he or she were somehow anchored.

The important take away from this discovery is that it will be very easy to break this kind of asteroid up, turning a large and big threat into a collection of small but harmless rocks.
