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.

American manned space: dependent on the Russians in more ways than you think

American manned space: dependent on the Russians in more ways than you think.

As commentators from around the country gnash their teeth at U.S. dependence upon Russia to move cargo and astronauts to the mostly U.S. built/funded International Space Station (ISS), they’ve missed the bigger boat: With one exception, all the commercial spaceflight offerings currently in the works have Soviet or Russian engines as a key part of the rockets involved.

ISS to be deorbited in 2020

7:47 am

The head of the Russian space agency said today that ISS will be deorbited in 2020, as agreed to by the governments running it.

Wanna bet? They are only now starting to do the research the station is best designed for, and learning how to live in space for years is going to take years. Come 2020, that work will hardly be done. Moreover, the impossibility of replacing ISS without a shuttle to haul up large modules and trusses will make very appealing the idea of keeping the present station in operation.

Then again, everything I just wrote is simple common sense, and who ever expected common sense from these governments?

Russia vows not to exploit manned space flight monopoly

7:21 pm

That’s so nice of them: Russia vows not to exploit its manned space flight monopoly.

Actually, this isn’t really news. Since the fall of the Soviet Union the Russians have always driven a hard bargain when they have sold tickets to get crew or cargo into space. However, once the contract has been signed they have also honored those contracts, to the letter. As the U.S. already has a signed contract to get its astronauts to ISS using Russian rockets and capsules, there won’t be any opportunities for Russian exploitation — until that contract expires.

In other words, the U.S. had better get some manned launch capability on line before too long. And on that note, see this article: NASA considers man-rating the Atlas V.

The U.S. and the rising Russian space program

12:48 pm

The Russians yesterday successfully launched their first space telescope since the fall of the Soviet Union. Here is a Google translation of a Russian article describing Spektr-R’s research goals:

[Spektr-R is] designed to study galaxies and quasars in the radio, the study of black holes and neutron stars in the Milky Way, as well as the regions immediately adjacent to the massive black holes. In addition, using the observatory, scientists expect to receive information about pulsars and the interstellar plasma. It is planned that the “Spektr-R” will work in orbit for at least 5 years.

Though this particular space telescope is probably not going to rewrite the science of astrophysics, its launch is historically significant. It indicates that Russia has just about recovered from the seventy-plus years of bankrupt communist rule that ended in 1990.

Human bones taken to ISS for long space flight experiments.

11:13 pm

Human bones were part of the cargo on board the Soyuz capsule launched to ISS today.

“The fragments of human bones will be used to study the causes and dynamics of decalcination of bone tissue in a long space flight,” the head of the experiment, Tatiana Krasheninnikova told Itar-Tass. The problem of decalcination is a headache for medics responsible for spacemen’s health. Researches in this area are conducted by scientists from many ISS member states. However it is impossible to take sample of spacemen’s bones, only their urine is being examined, and a complete picture of dynamics of changes in human bones is not clear, she noted.

Mars 500 mission passes one year

9:03 am

The Russian/ESA Mars 500 mission has completed a year of its 520-day simulated flight to Mars.

The crew, who spent 250 days working on maintenance and scientific experiments before a 30-day stint performing tasks on a simulated Martian surface, are currently on their “return trip” to Earth.

This simulated all-male flight is going better than the last:

In 1999, an experiment in the same Moscow warehouse fell to pieces after a Russian team captain forced a kiss on a Canadian woman, and two Russian crewmembers had a bloody fistfight.
