MESSENGER Begins Historic Orbit around Mercury

On board MESSENGER is the Fast Imaging Plasma Spectrometer (FIPS), a space instrument built by AOSS/SPRL at the University of Michigan. On March 17th, at 9:10 p.m. EDT, engineers in the MESSENGER Mission Operations Center at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., received the anticipated radiometric signals confirming nominal burn shutdown and successful insertion of the MESSENGER probe into orbit around the planet Mercury.
