SOLAR SYSTEM

Detailed explanation-1: -A probe is a spacecraft that travels through space to collect science information. Probes do not have astronauts. Probes send data back to Earth for scientists to study.

Detailed explanation-2: -Probes are a type of satellite. Instead of orbiting a planet as satellites do, probes travel through space and may carry telescopes and other instruments to study space objects such as planets, moons, asteroids, comets, and the Sun.

Detailed explanation-3: -A space probe is an unpiloted, unmanned device sent to explore space and gather scientific information. A space probe is launched from Earth with a set of scientific instruments and tools used to study the atmosphere and composition of space and other planets, moons, or celestial bodies.

Detailed explanation-4: -Space probes have helped scientists get information about our solar system. Most probes are not designed to return to Earth. Some have landed on other planets! Others have flown past the planets and taken pictures of them for scientists to see.

Detailed explanation-5: -We launch satellites and spacecraft into space by putting them on rockets carrying tons of propellants. The propellants give the rocket enough energy to boost away from Earth’s surface. Because of the pull of Earth’s gravity, largest, heaviest spacecraft need the biggest rockets and the most propellent.

Detailed explanation-6: -All of the data collected throughout the mission goes into an archive that can be accessed by scientists all over the world and used for further scientific research. Another aspect of work following the completion of a mission is to either start or continue working on the study of the next, follow-on mission.
