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. Sputnik 1 was the first probe to go into space.

Detailed explanation-2: -Usually, the word “satellite” refers to a machine that is launched into space and moves around Earth or another body in space. Earth and the moon are examples of natural satellites.

Detailed explanation-3: -Metis is an instrument known as a coronagraph, which captures images of the Sun’s dim outer atmosphere, the corona, by blocking light from Sun’s bright surface. Metis will image the corona in both visible and extreme ultraviolet light from closer than any previous coronagraph has gotten to the Sun.

Detailed explanation-4: -Orbiters are placed in orbit around a celestial body. Landers land on the surface of a celestial body.

Detailed explanation-5: -Voyager 1 was the first spacecraft to cross the heliosphere, the boundary where the influences outside our solar system are stronger than those from our Sun. Voyager 1 is the first human-made object to venture into interstellar space.
