Mars Odyssey Mission Status
May 23, 2001
NASA's 2001 Mars Odyssey spacecraft performed its first
trajectory correction maneuver this morning as it fired its
thrusters to fine-tune its flight path for arrival at Mars in October.
Odyssey fired its thrusters for 82 seconds at 10:30 a.m.
Pacific time, which changed the spacecraft's velocity by 3.6
meters per second (8.1 miles per hour).
"The maneuver executed as planned, and we are
very pleased with the spacecraft performance," said
David A. Spencer, mission manager for 2001 Mars Odyssey
at NASA's Jet Propulsion Laboratory, Pasadena, Calif.
"Due to the favorable launch we received, this
maneuver was much smaller than planned pre-launch.
This will allow us to reach Mars with our propellant tanks
nearly full, and we will make good use of the extra fuel."
The principal investigator for the high energy neutron
detector instrument reports the detection of gamma ray
bursts, occurring on May 8 and May 17. Comparing these
measurements with similar measurements from other
spacecraft allows scientists to determine the direction of
the burst sources. The high energy neutron detector and
the companion neutron spectrometer instrument also detected
streams of particles and radiation from enhanced solar
activity on May 20.
Odyssey is currently about 14.3 million kilometers
(8.9 million miles) from Earth and traveling at a speed of
about 29 kilometers per second (about 65,700 miles per
hour) relative to the Sun.
The Mars Odyssey mission is managed by the Jet
Propulsion Laboratory for NASA's Office of Space Science,
Washington, D.C. JPL is a division of the California
Institute of Technology in Pasadena. The Odyssey
spacecraft was built by Lockheed Martin
