CAPE CANAVERAL, Fla. -- In the Payload Hazardous Servicing Facility at the Kennedy Space Center in Florida, technicians tilt the massive Gamma ray Observatory GRO upright for installation onto the transporter which will carry it to the Vertical Processing Facility. The spacecraft is scheduled to fly aboard the space shuttle Atlantis on STS-37. As the second of four great observatories planned by NASA, GRO will study the celestial gamma rays believed to be a record of cosmic change and evolution. Photo Credit: NASA
