RAD: Radiation Assessment Detector
Principal Investigator: Donald Hassler,
Southwest Research Institute, Boulder, Colorado
Southwest Research Institute (SwRI)
is developing the Radiation Assessment Detector, or RAD, to characterize
the broad spectrum of radiation at the surface of Mars. The investigation
will determine the radiation hazards faced by future astronauts.
MSL will be the first mission to investigate the radiation environment
on the surface. There was to have been an instrument on the 2001
Mars Surveyor lander called MARIE. That mission was cancelled,
however. The 2001 Mars Odyssey did arry a MARIE instrument that
measured the radiation levels from orbit but the surface still
RAD is the Radiation Assessment Detector
for the 2009 Mars Science Laboratory mission.
