Got some good replies that maybe I’m wrong about UFOs. But assuming we’re mostly alone, I still don’t know whether to be sad or inspired by it. No neighbors means it’s all on us to explore and eventually move to other planets. 👽 Preferably not with balloon power. 🎈

@manton Balloons are actually great for exploring planets with atmospheres, for example Venus:

@manton Carl might disagree with you on not exploring with balloon power.

@amoroso That's really cool. Don't think I knew about that part of those missions.

@manton These days Mars helicopters are all the rage.
