SOLAR SYSTEM

Detailed explanation-1: -The spacecraft lander is a protective “shell” that houses the rover and protects it, along with the airbags, from the forces of impact. The lander is a strong, lightweight structure, consisting of a base and three sides “petals” in the shape of a tetrahedron (pyramid-shaped).

Detailed explanation-2: -A rover is a small, mobile robot that scientists send to moons and planets to land on their surfaces and explore. Rovers can take pictures and collect information about the planet by taking temperature readings, rock, and soil samples.

Detailed explanation-3: -Landed spacecraft can make detailed observations of a planet’s surface. However, these observations are restricted to a small area. To obtain coverage over a wider area, spacecraft can carry robots that are able to rove over the surface.

Detailed explanation-4: -The Lunar Roving Vehicle (LRV) is a battery-powered four-wheeled rover used on the Moon in the last three missions of the American Apollo program (15, 16, and 17) during 1971 and 1972. It is popularly called the Moon buggy, a play on the term “dune buggy".

Detailed explanation-5: -The Apollo lunar roving vehicle was a battery-powered space buggy. The astro-nauts on Apollo 15, 16, and 17 used it to explore their landing sites and to travel greater distances than astronauts on earlier missions. The lunar rover neatly folded up inside the lunar lander during trips to the Moon.
