NASA said on Tuesday that astronauts will try a new set of exercises to prepare them for the change in pressure they encounter on their spacewalk outside the International Space Station. The space agency said the "slow motion hokey pokey" exercises are designed to prevent decompression sickness known as the bends, which is similar to what scuba divers face if they rise to the surface too quickly. Astronauts typically get their spacesuits on early and take a series of steps, like breathing...

A faulty CO2 sensor has cut short the first spacewalk of the shuttle Endeavour astronauts, Fox News reports. Mission controllers noticed that Gregory Chamitoff's spacesuit sensor wasn't working and, erring on the side of safety, NASA had the astronauts return to the station until the issue could be assessed. Feustel and Chamitoff spent early Friday on routine chores outside the ISS, installing a light fixture here, covering something there, picking some stuff up. Chamitoff and spacewalking...

Astronauts Steve Bowen and Alvin Drew started the second spacewalk of the STS-133 mission on Wednesday morning. This is the 244th spacewalk performed by U.S. astronauts and the 155th in support of the International Space Station (ISS). Drew will complete the last task related to the failed ammonia pump module the two moved into a storage location on Monday. He will vent the remaining ammonia from the module into space by using a special tool to protect his spacesuit from any ammonia...

By Diego Urbina, Mars500 Crew Now that the Mars500 crew has been united, when the Marswalkers, 'returned' from the surface of the Red Planet to join the 'orbital' trio, Diego has again had time to send his thoughts. This diary was written on 21 February, before the last egress to the simulated martian surface. The last few weeks have been truly exciting. As you probably know, Wang, Aleksandr and I, transferred to the landing module, have been living in further isolation, in a reduced room...

Two Russian cosmonauts performed spacewalks outside the International Space Station (ISS) on Friday. The spacewalkers installed a camera and an experimental radio system outside the ISS during the mission. Cosmonauts Dmitry Kondratyev and Oleg Skripochka set up the radio antenna and routed cable for it, then tossed the cover and cable reel overboard. The experimental radio system is designed to transmit large data files to Russian ground controllers. The spacewalkers also retrieved a pair...

Space station astronauts have completed the third spacewalk to install a new pump to restore their cooling system back to full strength for the first time in two weeks. Douglas Wheelock and Tracy Caldwell Dyson spent over six hours installing the new ammonia pump during the spacewalk.  The astronauts removed the faulty pump during the second spacewalk on August 11. The International Space Station's (ISS) cooling system stopped running in full power since July 31 when an electrical...
