Nasa Blueshift

It's an exciting experience for any space geek to watch a new satellite launch into orbit. Earlier in 2012, we were excited about the launch of NuSTAR, a small explorer X-ray mission collaboratively created by teams at Caltech, NASA, and over a dozen other institutions around the world. NuSTAR advances the international astronomical community's ability to observe some of the hottest, densest, and most energetic objects in the Universe. We were interested to find out more about NASA Goddard's involvement in the mission, so we interviewed post-doc Dr. Dan Wik about his work with the satellite's optics and his interest in observing galaxy clusters with NuSTAR.
