SM4 EVA Astronauts practice installing Hubble's new panchromatic imaging instrument, the Wide Field Camera 3, during final underwater training.
SM4 EVA Astronauts John Grunsfeld and Andrew Feustel practice installing Hubble’s new panchromatic imaging instrument, the Wide Field Camera 3, during final underwater training at the Neutral Buoyancy Laboratory at the Johnson Space Center (JSC) in Houston, Texas. During the past year, SM4 astronauts have trained in simulators at JSC as well as on the actual flight hardware at the Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. The astronauts, assisted by a team of engineers from JSC and GSFC, have practiced spacewalking procedures, techniques for servicing Hubble, and using the many specialty tools that will help them efficiently work in space..    Credit:NASA  > View Larger Image
