The designer of spy satellite finally reveals his life’s work

8:02 pm

The designer of the spy satellite KH-9 HEXAGON (more generally known by its nickname “Big Bird”) has finally been able to describe his life’s work.

What surprised me most from this story is the fact that HEXAGON used film to record its images, not some form of digital or electronic technology. The film was returned to Earth in four “re-entry buckets” that were snatched out of the air by a modified C-130 airplane. I had assumed that by the time HEXAGON was launched they had abandoned film. Not so.

Space News suggests Congress use the billions for NASA’s heavy-lift rocket to fund JWST

3:51 pm

In an editorial yesterday Space News suggested that Congress use the billions it is allocating for NASA’s heavy-lift rocket to fund the James Webb Space Telescope instead.

This is not surprising. Webb already has a strong constiuency (astronomers, the public) while the Space Launch System has little support outside of Congress and the specific aerospace contractors who want the work. With tight budgets as far as the eye can see into the future, and the likelihood that Congress is going to become more fiscal conservative after the next election, it would not shock me in the slightest if SLS gets eliminated and the money is given to Webb. And if the SpaceX and Orbital Sciences cargo missions to ISS go well then cutting SLS would almost be a certainty, as this success would demonstrate that these private companies should be able to replace SLS for a tenth of the cost.

And I also think this would be a much wiser use of the taxpayers money.

The space police of Baikonur

The space police of Baikonur.

I find this quote interesting:

When the status of the city was designated [after the fall of the Soviet Union], the leased Baikonur was monitored by two Interior Ministries, two prosecutors’ offices and two state security organs. But social problems have not disappeared. Engineers and astronauts are not the only ones who live in the city. Baikonur hosts a great deal of people who have local residence papers, including the indigenous Kazakhs. They cannot work on Baikonur objects because mostly Russians are hired to work there. If the Kazakhs are lucky enough to be hired, they are paid far less than the Russians.

In June of this year mass uprisings occurred in Baikonur. A crowd of youths pelted a police patrol car with stones and bottles.

A new Arianespace rocket

10:00 pm

A new Arianespace rocket starts its journey to French Guiana.

This first launch, the Vega qualification flight, is planned for January 2012 and will pave the way for five missions that aim to demonstrate the system’s flexibility. . . . Vega is compatible with payload masses ranging from 300 kg to 2500 kg, depending on the type and altitude of the orbit required by the customers. The benchmark is for 1500 kg into a 700 km-altitude polar orbit.

This rocket is comparable to SpaceX’s now discontinued Falcon 1, though it can put more payload into orbit.

An update on the ongoing X-37B mission

An update on the ongoing X-37B mission.

I like this quote from the article:

Meanwhile, Boeing has begun to look at derivatives of their X-37B Orbital Test Vehicle — including flying cargo and crew to the International Space Station. Speaking this week at the Space 2011 conference —organized by the American Institute of Aeronautics and Astronautics (AIAA) and held in Long Beach, Calif. — Arthur Grantz of Boeing Space and Intelligence Systems sketched out a host of future uses for the space plane design. For one, the X-37B, as is, can be flown to the space station and dock to the facility’s common berthing mechanism. No new technology is required for X-37B to supply cargo services to the ISS, Grantz said. Also, an X-37C winged vehicle has been scoped out, a craft that would ride atop an Atlas 5 in un-shrouded mode.

The Boeing roadmap, Grantz added, also envisions a larger derivative of the X-37B space plane, one that can carry up to seven astronauts, as well as tote into Earth orbit a mix of pressurized and unpressurized cargo.

Test flights of SpaceShipTwo resume

9:22 am

After a summer break, the flight tests of SpaceShipTwo have resumed. Thursday’s test appeared to a bit more exciting that previous flights:

Test card called for releasing the Spaceship from WhiteKnightTwo and immediately entering a rapid descent. Upon release, the Spaceship experienced a downward pitch rate that caused a stall of the tails. The crew followed procedure, selecting the feather mode to revert to a benign condition. The crew then defeathered and had a nominal return to base. Great flying by the team and good demo of feather system.

Five myths about China’s space effort

9:04 am

Five myths about China’s space effort. Key recommendation:

Recognize the significance of space as a field of competition. Beijing is not engaged in a space race with Washington. But China is engaged in a great power competition with the U.S. in which space is one arena. American decision makers should come to terms with this duality. In this regard, the Chinese are unlikely to be manipulated by American proposals on “codes of conduct” or meetings with the head of NASA. As long as Beijing and Washington are in competition, space will be one of the major venues.

And competition is not a bad thing. It is going to be the fuel that gets the human race into space.
