ISS: Playing with fire

Up in the world's space outpost, astronauts and cosmonauts of Expedition 30 continue their research and experiments with living in space. Yesterday, astronaut Don Pettit worked on SLICE, the Structure and Liftoff In Combustion Experiment. SLICE allows astronauts and scientists to examine how flames behave in the microgravity of Earth orbit. The information gained by these tests will help engineers invent new equipment for fire safety which will benefit living in space, as well as potential benefits in fire control on Earth. This work will also help in pollution control and fuel efficiency in combustion engines.

During interviews with reporters, Flight Engineers Don Pettit and Andre Kuipers drank tea using specially designed glasses that allow humans to drink normally rather than have to sip liquid from plastic bags. After years of drinking from bags, this is a small but pretty cool step for living in space.

Other activities continued as normal aboard ISS: experiments with liquids and gasses in microgravity, computer and station maintenance, and astronaut physical workouts to control bone mass deterioration. Three of the crew practiced emergency evacuation procedures using the Soyuz TMA-22 spacecraft. Unloading continues from the Progress 46 supply spacecraft which docked at the station in January. Supplies from the module will continue to be unloaded, and eventually the module will be filled with trash, waste and garbage so it can be jettisoned later to burn up in the atmosphere.

What's next for ISS? On Wednesday the ISS will fire up its thrusters to boost its orbit a little bit. On March 9, the European Space Agency will launch another cargo spaceship (ATV-3) to the station. This craft has been nicknamed, "Edoardo Amaldi."
