It might not seem as interesting as the recent delivery of the new room and viewing dome to the ISS by the shuttle Endeavor, but another arguably more important task accomplished by the shuttle crew was the rejuvenation of the water recovery system on board the space station, with the distillation assembly being refurbished and the fluids control pump assembly replaced.
And so what you might be saying?!
Well the significance is that our bodies consist roughly of two thirds water and thus a continual intake is vital for survival. You could live on average between 3 to 7 days without water (depending on environment) but as little as a 10% fluid loss is likely to prove fatal if not treated immediately.
The space shuttle Endeavor landed successfully this Sunday 21st Feb 2010, at 10.20pm EST at Nasa´s Kennedy Space Centre in Florida, at the end of another 2 week mission to the International Space Station (ISS). Night time landings are quite rare with this being only the 23rd landing in darkness out of the 130 flights to date, the last one also involving Endeavour back in 2008.
The countdown clock is now well and truly ticking for the space shuttles, with only four more flights planned before they are moth-balled, never to fly again. The four remaining flights scheduled to end with the flight of Discovery, mission STS-133 in September this year, will be used to stock the ISS with more experiments, spare parts and supplies, with future provisions being delivered by spacecraft from Russia, Europe and Japan.
