A victory for aerospace pork

1:52 pm

Update: See my partial retraction here.

The NASA budget announced today by the White House proves how right I was when I stated back on July 8, 2010 that I had no faith in Obama’s new-found commitment to private commercial space. The new budget reduces the funds for private commercial space while putting the bulk of its support behind the unbuildable program-formerly-called Constellation. First read what I wrote in July:

The problem is that I simply do not believe the Obama administration. Everything I have learned about the current President, including the specifics (or lack thereof) of his proposal, tells me that none of his promises are going to be fulfilled. » Read more

Astronauts simulate Mars landing

9:14 pm

Astronauts on the Russian Mars500 simulated Mars mission simulated a Mars landing on Saturday. Key quote:

Three astronauts on the Mars500 simulated mission will make a simulated walk on the Mars “surface” Monday. After working 30 days on the simulated planet, the crew will then embark on a simulated 240-day return trip to Earth. Officials said the 520-day Mars500 mission is designed to test how humans cope with the physical and mental stresses of a long space flight.

SpaceX puts Dragon 9 space capsule on display in D.C.

11:02 am

SpaceX has put the Dragon 9 space capsule that flew in space on display in D.C. Though it is really cool that they are making the capsule so available to the public, this quote tells us the real story:

With Congress preparing in the weeks ahead to again address the question of government contracts for commercial space businesses such as SpaceX, the company wanted to give it (and attendees of the nearby FAA Commercial Space Transportation Conference) an opportunity to see the capsule. Members of Congress and of the Obama administration were invited to attend a Thursday evening viewing, and company officials said the response has been enthusiastic.

Companies team up on new rocket

10:55 am

The competition to build rockets continues to heat up: A U.S. and European partnership is proposing its own new cargo rocket for NASA, using the Ares I first stage and the Ariane 5 second stage. Key quote:

Dubbed Liberty, the launcher looks similar to the Ares I rocket that was being developed for NASA’s Project Constellation, which was cancelled by the Obama Administration. For its first stage it employs the same advanced, five-segment version of the shuttle’s solid rocket booster. But in a move that significantly lowers development costs, the second stage of the rocket is based on the flight-proven core stage of Europe’s Ariane 5 rocket.

Falcon 9 signed to launch Google Lunar X prize competitor

10:33 am

One of the competitor’s for the Google Lunar X prize has signed a contract with SpaceX to use the Falcon 9 to get its spacecraft to the Moon. Key quote:

The Falcon 9 upper stage will sling Astrobotic on a four-day cruise to the Moon. Astrobotic will then orbit the moon to align for landing. The spacecraft will land softly, precisely and safely using technologies pioneered by Carnegie Mellon University for guiding autonomous cars. The rover will explore for three months, operate continuously during the lunar days, and hibernate through the lunar nights. The lander will sustain payload operations with generous power and communications.

Remembering Columbia

8:01 pm

An evening pause: On this day eight years ago, the space shuttle Columbia broke up as it returned from orbit. Rather than watch that sad sight again, I’d rather remember the shuttle’s achievements. Watch this footage of Columbia’s first landing on April 14, 1981, which proved it was possible to glide powerless back from space and land safely on a runway. Though we as a nation might be abandoning this approach right now, future generations will use this as their standard way to return to Earth.

Several things to note as you watch the video. First, the shuttle’s angle of descent is extremely and frighteningly steep, until the very last moment. And every shuttle landing is like this. The shuttle is heavy, but it is still attempting to glide powerless to a landing. To do so it needs the thickness of the atmosphere combined with high speed to give it lift. Thus, it plows downward at a mucher higher speed and angle than any airplane, then quickly levels out at the last moment.

Secondly, this first landing did not have a drogue chute to slow the shuttle down. Rather than complicate things, they simply let the shuttle roll until it came to a stop.
