RIMFAX, one of the seven payloads of NASA’s Mars 2020 rover mission
RIMFAX, ground-penetrating radar will be used by NASA to study centimeter-scale resolution of the geologic structure of the subsurface on Mars.
RIMFAX - Radar Imager for Mars' Subsurface Exploration
Radar Imager for Mars' Subsurface Exploration (RIMFAX) was in news because it is among the seven selected payloads that will be sent to Mars with the Mars 2020 rover mission. RIMFAX is ground-penetrating radar and will provide centimeter-scale resolution of the geologic structure of the subsurface.
The Mars Rover 2020 mission will be sent to determine the potential habitability of the Mars environment, and directly search for signs of ancient Martian life.
Earlier, NASA on 31 July 2014 announced that it will send a new rover to Mars in 2020 named as Mars 2020 rover mission. The project would be launched in July or August 2020 and will land on Mars after an eight to nine month cruise in 2021. The mission will be developed and managed by the NASA's Jet Propulsion Laboratory.
Seven Payloads to be carried by the Mars 2020 rover mission
These seven instruments were selected from 58 proposals received in January 2014 from researchers and engineers worldwide.
