It isn’t often you get the chance to be in the same room with an astronaut. Even rarer is the opportunity to hear from an astronaut of John Grunsfeld’s caliber.

Today at 4 p.m., Grunsfeld will give a Fermilab Colloquium in One West.

A Chicago native and an astrophysicist, Grunsfeld is a veteran of five Space Shuttle flights and has clocked more than 50 hours spacewalking. He visited the Hubble Space Telescope on three of his space shuttle missions and serviced and upgraded the HST. He served as NASA’s chief scientist in 2003 and 2004, as deputy director of the Space Telescope Institute in Maryland from 2009 to 2011, and since January 2012 has been serving as associate administrator of NASA’s Science Mission Directorate.

The talk is free and open to the public.
