Sailing to Mars

9:15 am

With the end of the Mar500 simulated mission this coming Friday, the Russians are now proposing an eighteen month simulated Mars mission on board the International Space Station.

The Russians have been pushing to do this on ISS for years. Unfortunately, NASA has always resisted.

Yet, as I wrote in Leaving Earth, we will never be able to send humans to any other planets until we have flown at least one simulated mission, in zero gravity in Earth orbit, beforehand. Wernher von Braun pointed out this reality out back in the 1950s, and that reality has not changed in the ensuing half century. Not only will such a mission tell us a great deal about the medical issues of living in weightlessness for years at a time — issues that are far from trivial — it will give us the opportunity to find out the engineering problems of building a vessel capable of keeping humans alive during interplanetary flight, far from Earth.

The space police of Baikonur

The space police of Baikonur.

I find this quote interesting:

When the status of the city was designated [after the fall of the Soviet Union], the leased Baikonur was monitored by two Interior Ministries, two prosecutors’ offices and two state security organs. But social problems have not disappeared. Engineers and astronauts are not the only ones who live in the city. Baikonur hosts a great deal of people who have local residence papers, including the indigenous Kazakhs. They cannot work on Baikonur objects because mostly Russians are hired to work there. If the Kazakhs are lucky enough to be hired, they are paid far less than the Russians.

In June of this year mass uprisings occurred in Baikonur. A crowd of youths pelted a police patrol car with stones and bottles.

Soyuz crew returns safely to Earth, despite radio problems

9:16 am

One of the two three-man crews on ISS have returned safely to Earth, despite an unexpected communciations blackout during their descent.

In related news, the Russians have slightly delayed the launch dates for the next manned flights to ISS, which also means that the next test flight of Falcon 9/Dragon will have to be delayed until 2012. Moreover, the Russians are once again balking at allowing Dragon to dock with ISS on this first flight.

More Progress freighter crash investigation results

7:31 pm

More Progress freighter crash investigation results: it appears there was something that blocked the fuel supply.

“The exposed production defect was accidental,” [the investigation] said, adding the reason may be qualified as an isolated case only after checking all available engines.

This suggests that the problem was an isolated error and that, once they have cleared the available engines, they can start flying relatively quickly.

Some suggestions for keeping ISS occupied

Some suggestions for keeping ISS occupied.

I especially like Harman’s suggestion that the Russians consider landing in the U.S. during the winter, thereby allowing them to extend one crew’s occupancy of ISS into December, January, or even February. Also, he proposes the Russians send an unmanned Soyuz to ISS during testing of the rocket, thereby providing the crews onboard a fresh lifeboat. This is something they have done in the past on their previous space station Mir.

A preliminary cause for the Russian launch failure has been found

9:19 am

Good news: The Russians have pinned down a preliminary cause for the Progress launch failure last week.

Solving this quickly appears essential, as the space station was not really designed to fly unmanned.

Past NASA risk assessments show there is a one in 10 chance of losing the station within six months if astronauts and cosmonauts are not onboard to deal with any critical systems failures. The probability soars to a frightening one in two chance — a 50-percent probability — if the station is left without a crew for a year.
