KENNEDY SPACE CENTER, FLA. - Mission Specialist Piers J. Sellers, Ph.D., got some recent hands-on experience with equipment he will soon take into space. He is working with the SPACEHAB Oceaneering Enhanced Deployable latch release. The astronauts of the second Return to Flight mission, STS-121, were at the SPACEHAB facility in Cape Canaveral to participate in the Crew Equipment Interface Test (CEIT). This test allows the astronauts to become familiar with equipment they will be using on their upcoming mission. STS-121 is scheduled to launch in July aboard Space Shuttle Atlantis.
