      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 Astronautics, Denver.

        MARS ODYSSEY MISSION STATUS
        July 2, 2001

        NASA's 2001 Mars Odyssey spacecraft fine-tuned its flight
        path for arrival at Mars in October as it performed its second
        trajectory correction maneuver this morning.

        Odyssey fired its thrusters for 23 seconds at 9:30 a.m.
        Pacific time, which changed the spacecraft's velocity by 0.9
        meters per second (about 2 miles per hour).

        "Today's successful trajectory correction maneuver marks
        the completion of the mission's early cruise phase," said
        David A. Spencer, mission manager for 2001 Mars Odyssey at
        NASA's Jet Propulsion Laboratory. "All science payloads have
        been checked out and are operating well."

        The Odyssey flight team, he said, is now turning its
        focus to preparations for Mars orbit insertion and
        aerobraking, in which repeated passage through the upper
        atmosphere of the planet will be used to adjust the
        spacecraft's orbit.

        Last week, the team opened the door on the gamma ray
        spectrometer, managed by the University of Arizona in Tucson,
        and started taking data with the gamma sensor head. Initial
        data indicate that the detector performance is excellent.
        Odyssey is currently about 35 million kilometers (about
        22 million miles) from Earth and traveling at a speed of about
        27 kilometers per second (about 59,800 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 Astronautics, Denver.

          MARS ODYSSEY MISSION STATUS
          July 16, 2001

          At 8:30 a.m. Pacific time today, NASA's 2001 Mars Odyssey spacecraft
          passed the halfway point on its journey to Mars. It has been 100 days
          since Odyssey's launch and 100 days remain until it arrives at the red
          planet.

          "Odyssey is now closer to Mars than Earth. The spacecraft is healthy
          and all systems are looking good," said David A. Spencer, the
          Odyssey mission manager at NASA's Jet Propulsion Laboratory. "Planning
          for Mars approach and orbit insertion in October is our primary focus
          right now."

          The navigation team reports the spacecraft is right on course. To
          date, the Deep Space Network has taken 11 separate measurements
          using the so-called delta differential one-way range measurement, a
          technique that uses two ground stations to determine the angular position
          of the spacecraft relative to the known position of a quasar. The
          measurements provide the navigation team with an additional source of
          information, adding confidence to their estimates of the Odyssey flight
          path.

          Today, Odyssey is 45.8 million kilometers (about 28.5 million miles)
          from Earth and 30 million kilometers (about 19 million miles) from
          Mars, traveling at a velocity of 26 kilometers per second (58,000 miles
          per hour) relative to the Sun.

          The Mars Odyssey mission is managed by JPL 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 Astronautics, Denver.

            MARS ODYSSEY MISSION STATUS
            October 12, 2001

            Following last night's final planned course correction,
            NASA's 2001 Mars Odyssey spacecraft is now on target to enter
            Martian orbit later this month.

            At 0400 Universal time on Friday, Oct. 12 (9 p.m. Pacific
            time, Thursday, Oct. 11), Odyssey fired its small thrusters
            for three seconds, which changed the speed and direction of
            the spacecraft by 0.077 meters per second (0.17 miles per
            hour). Odyssey will arrive at Mars at 0226 Universal time
            Oct. 24 (7:26 p.m. Pacific time Oct. 23).

            "This was a tiny maneuver, designed to change our
            altitude at arrival by just a few kilometers. The burn went
            exactly as planned," said David A. Spencer, Odyssey's mission
            manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

            On Monday, Oct. 15, the flight team will uplink the
            sequence of commands that pre-programs the spacecraft to fire
            its main engine and allows the spacecraft to be captured by
            the planet's gravity and enter orbit around Mars.

            Today, Odyssey is 3.5 million kilometers (2.2 million
            miles) from Mars, traveling at a speed of 23 kilometers per
            second (51,800 miles per hour) relative to the Sun.

            The 2001 Mars Odyssey mission is managed by JPL 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
            Astronautics, Denver. The thermal emission imaging system is
            managed by Arizona State University, Tempe, and the gamma ray
            spectrometer is managed by the University of Arizona, Tucson.
            NASA's Johnson Space Center, Houston, built and manages the
            Martian radiation environment experiment.

              Mars Odyssey Mission Status
              October 30, 2001

              NASA's 2001 Mars Odyssey spacecraft took its first
              thermal infrared temperature image of Mars at approximately
              1300 Universal time (5 a.m. Pacific time) today. The imaging
              team at Arizona State University, Tempe will process the data
              over the next couple of days and hopes to release the image
              later this week. This morning's image is part of the
              calibration process for the thermal emission imaging system
              and is designed to help determine that the imaging system is
              working properly. The main science mapping mission is
              expected to begin in early February 2002.

              Flight controllers report the aerobraking phase is
              proceeding as planned. The first aerobraking pass, when the
              spacecraft slowly dips into the martian atmosphere to slow
              itself down, began on schedule last Friday night. Today,
              Odyssey is in its ninth pass around Mars. During its closest
              approach, the spacecraft is 128 kilometers (nearly 80 miles)
              above the surface and during its farthest point is 27,000
              kilometers (nearly 17,000 miles) away from Mars. Currently,
              Odyssey is in an elliptical orbit and aerobraking will
              circularize its path during the next three months.

              Following the orbit insertion last week, scientists
              turned on the high-energy neutron detector and the neutron
              spectrometer to check out and validate the instruments during
              the course of three orbits. Both instruments functioned well.
              Neutrons were successfully measured during each close pass by
              the planet. Those instruments have since been turned off.

              JPL manages the 2001 Mars Odyssey mission for NASA's
              Office of Space Science, Washington, D.C. Principal
              investigators at Arizona State University in Tempe, the
              University of Arizona in Tucson, and NASA's Johnson Space
              Center, Houston, Texas, operate the science instruments.
              Lockheed Martin Astronautics, Denver, Colo., is the prime
              contractor for the project, and developed and built the
              orbiter. Mission operations are conducted jointly from
              Lockheed Martin and from JPL, a division of the California
              Institute of Technology in Pasadena. NASA's Langley Research
              Center in Hampton, Va., will provide aerobraking support to
              JPL's navigation team during mission operations.

                Mars Odyssey Mission Status
                December 27, 2001

                Flight controllers of NASA's 2001 Mars Odyssey mission
                report that the aerobraking phase is proceeding right on
                schedule and should be completed in early January. During the
                aerobraking phase of the mission, the spacecraft is controlled
                so it skims the upper reaches of the martian atmosphere on
                each orbit, to reduce the vehicle's speed.

                Today, Odyssey's orbital period is three hours and 15
                minutes, compared with the initial 18-and-a-half hours when
                the spacecraft first entered orbit in October. The orbital
                period is the time required to complete one revolution around
                the planet.

                "We plan to perform a maneuver to raise the spacecraft
                up out of the atmosphere in early January. After that it will
                take about a month for us to circularize the orbit using our
                onboard thrusters and then prepare to start the science
                mission," said David A. Spencer, Odyssey's mission manager at
                NASA's Jet Propulsion Laboratory, Pasadena, Calif. The
                primary two-and-a-half year science mission is scheduled to
                begin in February.

                The high energy neutron detector provided by Russia's
                Space Institute has operated throughout much of the
                aerobraking phase and has completed its calibration in
                preparation for the science mission. The instrument is part
                of the gamma ray spectrometer payload suite, designed to map
                the elemental composition of the martian surface. Among its
                many science objectives, Odyssey will attempt to determine the
                amount and location of any near-surface water on Mars, if it
                exists.

                JPL manages the 2001 Mars Odyssey mission for NASA's
                Office of Space Science, Washington, D.C. Principal

                  Mars Odyssey Mission Status
                  January 11, 2002

                  Flight controllers for NASA's Mars Odyssey spacecraft
                  sent commands overnight to raise the spacecraft up out of the
                  atmosphere and conclude the aerobraking phase of the mission.

                  At 12:18 a.m. Pacific time Jan. 11, Odyssey fired its
                  small thrusters for 244 seconds, changing its speed by 20
                  meters per second (45 miles per hour) and raising its orbit by
                  85 kilometers (53 miles). The closest point in Odyssey's
                  orbit, called the periapsis, is now 201 kilometers (125 miles)
                  above the surface of Mars. The farthest point in the orbit,
                  called the apoapsis, is at an altitude of 500 kilometers (311
                  miles). During the next few weeks, flight controllers will
                  refine the orbit until the spacecraft reaches its final
                  mapping altitude, a 400-kilometer (249-mile) circular orbit.

                  "The successful completion of the aerobraking phase is a
                  major milestone for the project. Aerobraking is the most
                  complex phase of the entire mission and the team came through
                  it without a hitch," said David A. Spencer, Odyssey's mission
                  manager at JPL. "During the next month, we will be
                  reconfiguring the spacecraft to begin the science mapping
                  mission." The science mission is expected to begin in late
                  February.

                  During the aerobraking phase, Odyssey skimmed through the
                  upper reaches of the martian atmosphere 332 times. By using
                  the atmosphere of Mars to slow down the spacecraft in its
                  orbit rather than firing its engine or thrusters, Odyssey was
                  able to save more than 200 kilograms (440 pounds) of
                  propellant. This reduction in spacecraft weight enabled the
                  mission to be launched on a Delta II 7925 launch vehicle,
                  rather than a larger, more expensive launcher.

                  JPL manages the 2001 Mars Odyssey mission for NASA's
                  Office of Space Science, Washington, D.C. Principal
                  investigators at Arizona State University in Tempe, the
                  University of Arizona in Tucson, and NASA's Johnson Space
                  Center, Houston, Texas, operate the science instruments.
                  Additional science investigators are located at the Russian
                  Space Research Institute and Los Alamos National Laboratories.
                  Lockheed Martin Astronautics, Denver, Colo., is the prime
                  contractor for the project, and developed and built the
                  orbiter. Mission operations are conducted jointly from
                  Lockheed Martin and from JPL, a division of the California
                  Institute of Technology in Pasadena. NASA's Langley Research
                  Center in Hampton, Va., is providing aerobraking support to
                  JPL's navigation team during mission operations.
