What is a space probe?

Quick Answer

A space probe is an unmanned spacecraft sent to explore space, planets, moons, or other objects. Probes may fly by, orbit, land, or even return samples.

The Full Story

Space probes are robotic spacecraft designed to gather scientific data without a human crew onboard. They can be sent to fly past a target, orbit it, land on it, or enter its atmosphere, depending on the mission. Famous probes include Pioneer 10, Voyager 1, Cassini, and New Horizons, each of which expanded knowledge of the Solar System. Robotic probes are essential because they can go where humans cannot yet safely travel.
