Tea Party in Space argues for more money for commercial space
Andrew Gasser at the Tea Party in Space website today argues strongly for Congress to fully fund the new commercial space program at the $850 million amount requested by the Obama administration.
As much as I am for these new commercial companies, I do not think it a good idea to fund them at these high levels.
For one thing, the government is still broke. It can’t afford to spend that much money. It is therefore unseemly for a website that uses the “tea party” label to advocate more spending at this time.
For another, the more money the government commits to these companies, the more control the government is going to demand from them. Far better to keep the government participation as small as possible. Make it just enough to allow the companies to succeed but not enough so as to make the whole effort a government program.

NASA Is Considering Fuel Depots in the Skies
NASA is considering putting fuel depots in orbit.
Under the plan outlined in the document, the propellant depot would be launched first, and then other rockets would carry fuel to the depot before a spacecraft arrived to fill up. That would increase the complexity for an asteroid mission — 11 to 17 launchings instead of four — but could get NASA astronauts to an asteroid by 2024, the study said. The total budget needed for the project from 2012 through 2030 would be $60 billion to $86 billion, the study said.
By contrast, a study last year that designed an asteroid mission around a heavy-lift rocket estimated that it would cost $143 billion and that the trip could not happen until 2029. The earlier study briefly considered propellant depots but quickly dismissed them.
This idea of putting fuel depots in space merely mirrors the 1960s proposal of using the Gemini capsule and the Titan rocket to assemble a spaceship in orbit for getting to the moon. According to the earlier proposal it would have been faster and cheaper to use existing smaller rockets and many additional launches than to build a giant Saturn 5 rocket that could put everything into orbit in only one launch. I have always thought this idea had merit.
The fuel depot concept is further confirmation that a heavy-lift rocket is not necessarily the only way one can get humans beyond Earth orbit.

Orbital announces revised schedule for its initial Taurus 2 and Cygnus flights
Orbital Sciences has announced its revised schedule for the initial Taurus 2 and Cygnus flights.
Orbital will conduct a test of the Taurus 2’s first stage on the launch pad in late January [2012], and the inaugural Taurus 2 flight in late February or early March. This will be followed, in early May, by a Taurus 2 flight carrying the Cygnus station cargo vehicle, a flight during which Cygnus is expected to demonstrate its ability to berth with the station. The first operational space station cargo-delivery mission for Taurus 2 and Cygnus will occur in late August or early September under this revised schedule, Orbital officials said.
Based on conversations I’ve had with people at Orbital, this delay was expected, and is a good thing. The company was under incredible time pressure to get ready for a December launch. Given that this will be the first test flight of Taurus 2, and it must work for the Cygnus cargo flights to follow, better they give themselves some working room to get it right.

Elon Musk and the forgotten word
When Elon Musk gave his speech at the National Press Club on September 29, he was asked one question to which he really did not know the answer. He faked it, but his response illustrated how completely forgotten is one fundamental fact about American society — even though this fact is the very reason the United States became the world’s most wealthy and powerful nation less than two centuries after its founding.
To explain this fundamental fact I think I need to take a step back and talk about the ongoing war taking place right now over how the United States should get its astronauts into space. On one side we have NASA and Congress, who want NASA to build a new heavy-lift rocket to carry its Orion capsule beyond Earth orbit. On the other side we have a host of independent new space companies, all vying for the chance to launch humans and cargo into space for fun and profit.
Which is right? What system should the United State choose?

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

Robot gas attendants could keep old satellites chugging.
MDA has a contract, and a good design. If they succeed in refueling an old communications satellite with a robot, it will be fundamentally change the launch industry. If satellites don’t have to be replaced as often, there will less need for launches, reducing the demand for rockets.

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