Another challenge: unless you want to analyze vapor traces, the sample needs to be kept frozen during the EDS phase.

<p>Could it be possible to send out something similar to a probe to one of the moons in the solar system that most likely have water under the cover of the ice and then bring back tests to Earth to see what it contains, or somehow try to drill into the ice?</p>

A "sond"? Do you mean a "probe"?

@AtmosphericPrisonEscape they probably meant "sonde" - https://www.dictionary.com/browse/sonde - as someone with your username should already know.. ;-p

@AaronF "Sonde" means literally that, in another language, thanks anglocentric imperial person.

Are you asking if it could be done now, or in the near future, or if there are any current plans to do so?

@AtmosphericPrisonEscape "anglocentric imperial person"? WTF? What was that for? Anyway: "Sonde" does not "literally" mean "probe". A sonde is a _type_ of probe. I thought that the OP wanted to use the correct word but typo-ed the final 'e'.

This is called a "[sample & return mission](https://en.wikipedia.org/wiki/Sample-return_mission)" and is possible, but would be a significant challenge.

The icy moons are all around Jupiter and beyond. You would need to:

1. Launch from Earth,
2. Boost to the orbit of Jupiter
3. Slow down and be captured into Jupiter's orbit
4. Land on the moon
5. Lift off from the moon
6. Escape Jupiter's orbit
7. Slow down and land on Earth.

Each step requires fuel, and the fuel for each step of the mission needs to be carried during the previous steps. The application of the rocket equation makes this hard.

In reality, we have done sample and return missions to the moon and to asteroids, which are closer and have much lower fuel requirements.

So, while such a mission is possible and would be scientifically valuable, it would represent a huge technical challenge.
