SOLAR SYSTEM

Detailed explanation-1: -The Perseverance rover will gather samples from Martian rocks and soil using its drill. The rover will then store the sample cores in tubes on the Martian surface. This entire process is called “sample caching". Mars 2020 will be the first mission to demonstrate this on Mars.

Detailed explanation-2: -Because of the limited flexibility of the spacesuits, it was not possible for an astronaut to place samples into a collection bag attached to his own backpack. Instead, he would place his samples into a collection bag attached to another astronaut’s backpack.

Detailed explanation-3: -Returning Mars Samples to Earth A Sample Return Lander would land near or in Jezero Crater, bringing a small rocket on which the samples collected by Perseverance would be loaded. Two Ingenuity-like helicopters would provide a secondary capability to retrieve samples on the surface of Mars.

Detailed explanation-4: -The Apollo Moon rocks were collected using a variety of tools, including hammers, rakes, scoops, tongs, and core tubes. Most were photographed prior to collection to record the condition in which they were found.
