Blueshift - September 30, 2009: John Grunsfeld: Astronaut and Astronomer
from NASA Blueshift · host NASA Goddard Space Flight Center
This summer, the world was watching as seven astronauts visited the Hubble Space Telescope and did the first ever on-orbit repairs in space. This fifth and final Shuttle mission to service Hubble has equipped the telescope with cutting-edge technology and extended its mission lifespan for several additional years. Here at the Astrophysics Science Division, we are excited about the data being captured by Hubble's enhanced instruments, and the discoveries that are sure to come. One of the astronauts on this mission, Dr. John Grunsfeld, is also an astrophysicist. We interviewed him about his experiences with Hubble as both a researcher and a repairman. He shared his thoughts about Hubble's new capabilities, the value of astrophysics, and more. He also told us about a gorgeous image he snapped on a previous servicing mission and is now using as a screensaver - and you can download this image for your own computer!
