Radar for Mars Gets Flight Tests at NASA Dryden
Jet Propulsion Laboratory
June 21, 2011
Southern California's high desert has been a stand-in for Mars for NASA
technology testing many times over the years. And so it is again, in a
series of flights by an F/A-18 aircraft to test the landing radar for
NASA's Mars Science Laboratory mission.
The flight profile is designed to have the F/A-18 climb to 40,000 feet
(about 12,000 meters). From there, it makes a series of subsonic,
stair-step dives at angles of 40 to 90 degrees to simulate what the Mars
radar will see while the spacecraft is on a parachute descending through
the Martian atmosphere. The F/A-18 pulls out of each dive at 5,000 feet
(about 1,500 meters. Data collected by these flights will be used to
finesse the Mars landing radar software, to help ensure that it is
calibrated as accurately as possible.
The testing is a collaboration of NASA's Dryden Flight Research Center,
Edwards, Calif., with NASA's Jet Propulsion Laboratory, Pasadena, Calif.
Earlier tests, with a helicopter carrying the test radar, simulated the
lower-altitude portion of the spacecraft's descent to the surface of
Mars. For more information about the F/A-18 tests, see
The Mars Science Laboratory mission's rover, named Curiosity, will be
shipped this month from JPL to NASA's Kennedy Space Center in Florida to
be readied for launch between Nov. 25 and Dec. 18, 2011. The spacecraft
will arrive at Mars in August 2012. After Curiosity lands on Mars,
researchers will use the rover's 10 science instruments during the
following two years to investigate whether the landing area has ever
offered environmental conditions favorable for microbial life.
JPL, a division of the California Institute of Technology in Pasadena,
manages the Mars Science Laboratory Project for the NASA Science Mission
Directorate, Washington. More information about the mission is online
