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: -A space probe is any unmanned spacecraft designed to carry out physical studies of the Moon, other planets, or outer space. Space probes take pictures, measure atmospheric conditions, and collect soil samples then bring or report the data back to Earth.
Detailed explanation-3: -There are a few other space probes that have reached, or are about to reach, the ‘boundary’ of our solar system, which is extremely far away, as you can imagine. Now, space probes, by definition, are robotic spacecraft, meaning that they don’t have humans onboard.
Detailed explanation-4: -Something that’s unmanned doesn’t have a driver, pilot, captain, or anyone else controlling or steering it. An unmanned space mission is launched without human passengers or crew.
Detailed explanation-5: -High-energy Particle Detectors. Voyager’s Cosmic Ray Subsystem (CRS). Low-Energy Charged-Particle Detectors. Plasma Instruments. Dust Detectors. Magnetometers. Plasma Wave Detectors. Mass Spectrometers. Planetary Radio Astronomy Instruments. More items
