Science, Spacewalk Preps and Station Orientation for Crew
After a day of Russian and U.S. human spaceflight anniversary activities, the Expedition 27 crew is back at work aboard the International Space Station. On April 12, 1961, cosmonaut Yuri Gagarin became the first human in space. Space shuttle Columbia launched on April 12, 1981, beginning STS-1, the first shuttle mission.
Inside the Columbus laboratory Flight Engineer Cady Coleman removed a microscope and spectrophotometer from the Biolab rack. Both items were not working and will be returned on space shuttle Endeavour when STS-134 ends. Biolab is a life sciences facility that observes the adaptation of organisms, from single-celled to humans, in microgravity.
Coleman also worked in the Destiny laboratory on setting up for an experiment that monitors maximum oxygen uptake of a crew member during long-term missions in space. Dubbed V02MAX, the experiment observes crew members during strenuous activities such as exercise and spacewalks. Coleman is to participate in the experiment Thursday.
