PUBLIC INFORMATION OFFICE JET PROPULSION LABORATORY CALIFORNIA INSTITUTE OF TECHNOLOGY NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PASADENA, CALIF. 91109. TELEPHONE (818) 354-5011 Contact: Franklin O'Donnell FOR IMMEDIATE RELEASE July 27, 1995
Details of the engine firing will be discussed in a press briefing by Galileo Project officials to be held at 10 a.m. Pacific Daylight Time today (July 27) at NASA's Jet Propulsion Laboratory, 4800 Oak Grove Drive, Pasadena, CA. The briefing will be carried live on NASA Television.
The main engine could not be tested or fired prior to release of the atmospheric probe because the probe was mounted in front of the engine nozzle.
The orbiter deflection maneuver was designed to change the spacecraft's velocity by 61.9 meters per second (about 140 miles per hour).
The Galileo spacecraft, which will enter orbit around Jupiter on December 7, will conduct a two-year-long, detailed study of the planet, its moons and magnetic environment, and return data from the atmospheric probe, which will dive into Jupiter December 7.
Galileo was launched in October 1989 aboard Space Shuttle Atlantis from NASA's Kennedy Space Center, FL. Galileo's Jupiter atmospheric probe is managed by NASA's Ames Research Center, Mountain View, CA. The Galileo spacecraft was built and the overall mission is managed by JPL.
