It’s been an exciting week on the International Space Station. On Monday, it had to dodge an old upper stage that was in danger of colliding with it. Then, yesterday, a reaction-control thruster unexpectedly fired for half a minute, causing a sudden unplanned shift in the facility’s attitude. Fortunately, the system reacted well overall, and things were restored to normal within a couple hours.
The misfiring thruster was on the Russian Soyuz capsule currently attached to the ISS. This is the vehicle in which it is planned to bring three crew members back to earth later tomorrow morning.
VADM Dyer also appeared to be against the notion of downselecting to one partner ahead of time, as has been intimated as a cost-saving option by some lawmakers.
“The thinking there is: If you need a house, why would you want to build two houses? Why not select one?” added the minutes. “VADM Dyer opined that it is a ‘very complicated house.’ The ASAP believes that competition brings the best of both providers to the fore.
“It also allows NASA to watch these two approaches and companies mature before making a downselect. The Panel stands foursquare in support of competition, as does NASA.”
It was also notable that NASA managers responded by stressing the ongoing discrepancy between the requested budgets for the Program and what has been appropriated.
With the two companies under fixed-price contracts, it was noted that it is important for all to recognize that if NASA does not receive the appropriations that it is counting on, it will have a very significant impact on schedule, and we will end up relying on the Russians beyond the 2017 target.
Some thoughts from Sam Dinkin over at The Space Review, with a plug for the Kickstarter, which has slowed since the burst last week. About half way to the goal, with a little over half the time left. Spread the word, at Facebook and other places, if you haven’t already.
Razid Khan has a defense of him. But not a very robust one. As I noted to Razid on Twitter, while we are certainly capable of extincting ourselves, it won’t be from resource depletion.
This effort would require four launches of NASA’s Space Launch System (SLS) megarocket, which is currently in development and is scheduled to make its maiden flight in 2018.
The purpose of my Kickstarter is to show how it could be done, faster, cheaper, with more people.
