In August's episode, we talk about how astronomers took the first ever image of the Milky Way, not with electromagnetic radiation, but with neutrinos, and CHAPEA, NASA's mission that involves locking away four crew members for a year to help plan for future human missions to Mars.

At the start of August, join the conversation on Twitter (@ROGAstronomers) and tell us what personal item you would bring if you were one of the CHAPEA crew members.
