b. Mars Retrieval Orbiter
c. Mars Reconnaissance Orbiter
d. None of the above

ANSWER: Mars Reconnaissance Orbiter
 
Using radar data from Nasa's Mars Reconnaissance Orbiter (MRO), scientists have found a record of the most recent Martian ice age recorded in the planet's north polar ice cap.
  • The new results agree with previous models that indicate a glacial period ended about 400,000 years ago as well as predictions about how much ice would have been accumulated at the poles since then.
  • The researchers identified a boundary in the ice that extends across the entire north polar cap. Above the boundary, the layers accumulated very quickly and uniformly, compared with the layers below them.
