How do planets get their names? With the exception of Earth, the planets in our solar system were named after Greek or Roman gods. Today, the job of naming things in space falls to the International Astronomical Union (IAU), the internationally recognized authority for naming celestial bodies and their surface features.

We know the Moon contains water, but, could future astronauts access and make use of it? That’s the goal. At NASA, we’re actively trying to answer that question. Once it lands at the lunar south pole, our PRIME-1 — Polar Resources Ice Mining Experiment-1 – will robotically sample and analyze ice from beneath the lunar surface, contributing to our search for water on the Moon.
