Contractor proposes taking over two shuttles and flying them for NASA through 2017

12:53 pm

The contractor who manages the shutte program for NASA, United Space Alliance (USA), has proposed taking over two shuttles and flying them privately for NASA through 2017. Key quote:

USA’s current estimated price tag of $1.5 billion per year would represent a substantial drop from previous funding levels, which have seen shuttle program costs rise as high as $4 billion per year. United Space Alliance says its plan would take advantage of shuttle infrastructure and a workforce already in place. Some shuttle production lines would have to be restarted — for example, the operation that builds the shuttle’s external fuel tanks. But USA says the first commercial shuttle flights could take place in 2013. That would beat the 2016 deadline specified in last year’s legislation, as well as the development schedule laid out by SpaceX and USA’s other commercial competitors.

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.

Challenger, 25 years later

11:03 am

Today is the 25th anniversary of the Challenger accident. There are innumerable links from many sources talking about the event, too many for me to list here. You can find most at this link on Jeff Foust’s website, spacetoday.net.

Though I think it is very important for us to remember and honor these events, I have become somewhat disenchanted with the modern American obsession with memorials and anniversaries. Rather than build a memorial, I’d much rather we focused entirely on building new spaceships, new space stations, and new lunar bases, while flying multi-year missions on ISS, all in preparation for exploring and colonizing the solar system.

If we actually made the solar system a place for humans to live in and explore, we would build a far better memorial to those who have sacrificed their lives for the sake of exploration. And I think these heroes would be far more pleased by that memorial than by a stone statue or emotional op-ed that describes their courage.

Astronaut Tim Kopra, member of next shuttle crew, injured in bike mishap

10:24 am

The lead spacewalker for the next shuttle mission, the long-delayed last flight of Discovery, has apparently broken his hip in a bike accident. Key quote:

NASA does not train backup crews and a replacement, even a recently flown veteran, would need time to rehearse spacewalk scenarios and receive mission-specific training for Discovery’s flight. How long that might take, if required, and what impact it might have on the shuttle’s launch date is not yet known.
