Which of the following statements is/are correct about the ‘curiosity’ mars rover (a robotic vehicle) launched by NASA to explore the ‘red-planet’?

1. There is a radiation sensor onboard on the curiosity rover called Radiation Assessment Detector (RAD) to explore the radiation level on the surface of Mars.

2. All pictures of the rover on the surface of Mars are taken using a high-resolution colour camera mounted on an orbiter moving around Mars that was part of the same mission.

Explanation:

Statement 2 is incorrect: Pictures of the Mars rover on the surface of Mars are usually taken by the colour camera (Mars Hand Lens Imager; MAHLI) mounted on the turret at the end of the Marse Science Laboratory (MSL) robotic arm.

Supplementary notes: Radiation on Mars and Curiosity Rover Unlike Earth, Mars doesn’t have a magnetic field to shield it from the highenergy particles coming closer to the surface and moving around in space. That radiation can cause severe damage to human health, and it can seriously compromise the life support systems that Mars astronauts will depend on, as well.

Based on data from Curiosity’s RAD, researchers are fi nding that using natural materials such as the rock and sediment on Mars could offer some protection from this ever-present space radiation. In a paper published this summer in JGR Planets, they detailed how Curiosity remained parked against a cliff at a location called “Murray Buttes” from Sept. 9 to 21, 2016.

The Mars Hand Lens Imager (MAHLI) is a focusable colour camera located on the turret at the end of the MSL robotic arm. The instrument acquires images of up to 1600 by 1200 pixels with a colour quality equivalent to that of consumer digital cameras.
