I would have believed that there's some tech that allows an orbiter to detect water under the surface. It seems that such a thing doesn't exist. What's next, droping bombs to study debris and ground waves?
- pacaro 8y agoI don’t know about bombs per se but plenty of stuff has been deliberately crashed into the moon to study its seismic structure etc.
- reaperducer 8y agoI don't remember if the moon was the target, but I recall there was a probe in the last 30 years or so that was deliberately crashed into something just to study the debris that was kicked up.

- InclinedPlane 8y agoThe technology does exist it's called radar, and there is already a mission on the books (the Jupiter Icy Moons Explorer, or JUICE) which will take just such an instrument to Jupiter and its moons in the early 2020s. P.S. There's also Europa Clipper, but the funding is less certain: https://en.wikipedia.org/wiki/Europa_Clipper https://en.wikipedia.org/wiki/Europa_Clipper
- Sharlin 8y agoRadar has also been used to map underground ice deposits on Mars, see eg. [1][2]. [1] https://en.wikipedia.org/wiki/SHARAD https://en.wikipedia.org/wiki/SHARAD [2] https://en.wikipedia.org/wiki/MARSIS https://en.wikipedia.org/wiki/MARSIS
