Why do we send probes to outer planets instead of astronauts?
AstronomySpace exploration
Quick Answer
Outer planets are extremely distant, cold, and radiation-heavy, so robotic probes are far safer and cheaper than crewed missions.
The Full Story
Jupiter, Saturn, Uranus, and Neptune are so far away that travel can take many years. Jupiterβs strong radiation belts are especially dangerous for humans and electronics, and all the outer planets are far too cold and remote for easy rescue or supply. Robotic probes can survive long voyages with less life support, and they are designed for detailed scientific observation without risking astronauts. That is why missions like Voyager, Galileo, Cassini, Juno, and New Horizons have been robotic.
Key Facts
