Falcon 9 has cleared the tower

12:46 am

Falcon 9 has cleared the tower and is “looking good.”

First stage has completed its job and has been released. The second stage is firing as planned.

Dragon has separated from the second stage and is now in orbit. Now comes the real test of this mission: Can Dragon maneuver and rendezvous with ISS?

The best moment for the entire launch sequence was when Dragon’s solar arrays deployed. The camera link was still working, so that everyone could see it. When the arrays locked open, there was a gigantic roar from the crowd of people watching at SpaceX’s mission control. Dragon was in orbit and operational!

The countdown has begun

9:37 pm

Tonight’s Falcon 9 launch: The countdown has begun, and the weather conditions have improved.

SpaceX will begin its own webcast at 3 am (Eastern), which is midnight here in Arizona.

An aside: The ashes of actor James Doohan, who played Scotty on the 1960s television show Star Trek, will be among 308 other cremated remains launched into space by Falcon 9 tonight. As one commenter for the above article noted quite appropriately,

You haven’t really covered any of the important questions here.

i.e. Are there enough dilithium crystals in the engine room to get Scotty up there? And are they using photon torpedoes to blast him out into space? And when they launch, will someone say, “Take her out, Mr. Sulu. Warp factor one.”?

Godspeed, Scotty old bean.

Falcon 9 aborted its launch tonight at 4:55 am (Eastern) at T minus zero seconds.

No go: Falcon 9 aborted its launch tonight at 4:55 am (Eastern) at T minus zero seconds.

Just after ignition there was a shutdown. They were able to make the vehicle safe, and are trying to figure out what happened. It appears there was a high pressure reading in one engine.

The next opportunity to launch is three days hence, though whether they will go for it then depends on whether they can figure out what caused the shutdown.

Update: More details here.

SpaceX has delayed the launch of its Dragon test mission to ISS, with the launch now scheduled sometime between May 3 and May 7.

SpaceX has delayed the launch of its Dragon test mission to ISS, with the launch now scheduled sometime between May 3 and May 7.

“After reviewing our recent progress, it was clear that we needed more time to finish hardware-in-the-loop testing and properly review and follow up on all data,” SpaceX spokeswoman Kirstin Brost Grantham wrote in an email. “While it is still possible that we could launch on May 3rd, it would be wise to add a few more days of margin in case things take longer than expected. As a result, our launch is likely to be pushed back by one week, pending coordination with NASA.”

Coming and going

9:10 am

There are really only two important stories today concerning space exploration. The story that is getting the most coverage is the big news that the space shuttle Discovery is making its last flight, flying over Washington, DC, as it is delivered to the Smithsonian for permanent display.

Of these stories, only Irene Klotz of Discovery News seems to really get it. This is not an event to celebrate or get excited about. It is the end of an American achievement, brought to a close probably three to five years prematurely so that the United States now cannot even send its own astronauts to its own space station.

The other news, actually far more important, has gotten far less coverage, and includes three different stories all really about the same thing.

Europe has shut down the production line producing their ATV cargo craft for ISS.

10:39 am

Is this good or bad news? Europe has shut down the production line producing their ATV cargo craft for ISS.

Confronted by parts obsolescence and waning political support, the European Space Agency has shut down subsystem production lines for the Automated Transfer Vehicle as member states debate how they will contribute to future international space exploration efforts, according to top spaceflight officials.

ESA has launched three of the five ATVs it agreed to launch, with the remaining two scheduled in 2013 and 2014. What happens after that remains unclear. It seems from the article the European partners don’t seem interested in upgrading the ATV, and instead seem willing to let the as-yet untried U.S. commercial companies carry the load.

Commercial flights by U.S. spacecraft will make up the rest of the lost capacity with the end of the ATV program.

The pressure continues to build on a successful Falcon 9/Dragon flight on April 30.

Space exploration and the unexpected consequences of government decisions

4:24 pm

On Thursday, December 15, 2011, NASA management announced what seemed at first glance to be a very boring managerial decision. Future contracts with any aerospace company to launch astronauts to and from the International Space Station (ISS) will follow the same contractual arrangements used by NASA and SpaceX and Orbital Sciences for supplying cargo to the space station.

As boring that sounds, this is probably the most important decision NASA managers have made since the 1960s. Not only will this contractual approach lower the cost and accelerate the speed of developing a new generation of manned spaceships, it will transfer control of space exploration from NASA — an overweight and bloated government agency — to the free and competitive open market.

To me, however, the decision illustrates a number of unexpected consequences, none of which have been noted by anyone in the discussions that followed NASA’s announcement back in mid-December.
