Question

The robotic rover Curiosity has instruments that detect radiation both inside the spacecraft and in the Mars environment. What is most likely the purpose of this radiation detection?
a)to determine whether human exploration of Mars is possible
b)to develop better X-ray technology
c)to find evidence of once-living Martian microorganisms
d)to investigate evidence of hydrogen and water

Answer 1

d)ti investigate evidence of hydrogen and water

Answer 2

Curiosity rover on mars soil has two type of radiation detectors.

They are  

RAD- Radiation Assessment Detectors

DAN- Dynamic Albedo of Neutrons

RAD was appointed to collects the data of dosage of radiation to which people are about to expose during the future mars exploration.

DAN was appointed to collects the data of presence of hydrogen molecule. If there is hydrogen there will be water under the surface of mars either in form of ice of water holding minerals.

Hence the correct answer for your question is option (D)- To investigate evidence of hydrogen and water.
