An update on the Falcon 9 engine problems.

An update on the Falcon 9 engine problems.

Based on SpaceX’s press release, the rocket functioned as designed to overcome the engine failure. Nonetheless, it behooves them to find out why that engine shut down prematurely.

More worrisome for the company is the failure the Falcon 9 rocket to place in its proper orbit a secondary payload, an Orbcomm communications satellite. The satellite ended up in too low an orbit, probably because of the engine failure during launch. Orbcomm has a contract with SpaceX to launch a whole series of these satellites. This failure now, right at the get-go, won’t do them much good in terms of public relations.

One engine of the Falcon 9 failed during launch.

Confirmed: One engine of the Falcon 9 exploded during launch.

Video at the link. The other 8 engines picked up the slack — as designed — and got Dragon into orbit.

This spectacular engine failure will of course have to be reviewed. However, if I were a commercial satellite company looking for a rocket to get my satellites into orbit, this failure would be recommendation, not a deterrent. The Falcon 9 demonstrated that even if one engine fails (and this one did by blowing up!), the rocket can survive the failure and make it to orbit. If that isn’t clear proof that this is a well designed and well built rocket, nothing is.

NASA and the Russians have agreed to fly a two-person year long mission on ISS beginning in the spring of 2015.

It’s now official: NASA and the Russians have agreed to fly a two-person year long mission on ISS beginning in the spring of 2015.

NASA has denied that this agreement has any connection with the Sarah Brightman/Russian deal, but I still wonder. Either way, it is very good news. Not only will they finally be using ISS appropriately, a mission like this will generate some real excitement for space exploration that the repeated boring six month expeditions to ISS have failed to do. Even better would be to schedule a two year mission, simulating a journey to and from Mars.

In order to get a seat on a Soyuz capsule Sarah Brightman outbid NASA, bumping its astronaut out and thus forcing the U.S. agency to finally agree to a year long mission.

Irony of ironies: In order to buy her seat on a Soyuz capsule Sarah Brightman outbid NASA, bumping its astronaut out.

This was a win-win for the Russians. They get paid more by Brightman than by NASA (over $51 million), and they finally get that year long mission they’ve been campaigning for for years. Because Brightman has taken one of NASA’s seats, the U.S. agency was forced to agree to the extended mission in order to maintain a presence on the station throughout that time period. Otherwise, their astronaut would come home and be replaced by Brightman, but for only ten days.
