A probe is a device used to explore the unknown. It can be used to measure the temperature, pressure, or other physical properties of a system, or to detect the presence of life. Probes have been sent to all corners of the solar system and beyond, in an effort to better understand our place in the universe.
The first probes were launched in the early 1950s, and since then they have become increasingly sophisticated.Today’s probes are capable of carrying out complicated tasks such as landing on Mars or taking pictures of distant galaxies. They are also used for more mundane tasks such as measuring air pollution levels or checking for leaks in pipelines.
Probes come in many different shapes and sizes. Some are designed to be reusable, while others are expendable. The most common type of probe is the spacecraft, which is designed to carry out specific missions and then return to Earth. Spacecraft can be either manned or unmanned; those that carry people are called “space shuttles.”
Manned spacecraft are typically much larger than their unmanned counterparts and require a crew of astronauts to operate them. Unmanned spacecraft can be controlled remotely by ground controllers or may be programmed to operate independently.
