Wednesday, August 4, 1999


CNN posted this report today. It describes the astroseismology results which Derek Buzasi is getting with the WIRE star tracker. Goddard configured the spacecraft to collect high-rate, raw star tracker data, and IPAC generates the timelines needed to collect the science data. Buzasi is studying the variation in the brightness of stars and comparing it to models of stellar oscillations.
