DA Baracus Posted October 23, 2019 Share Posted October 23, 2019 Yes, I've phrased that poorly. The liquid there might not be water but another type of liquid. How do they know it's H2O? 0 Quote Link to comment Share on other sites More sharing options...
Stellaboz Posted October 23, 2019 Share Posted October 23, 2019 I'm assuming they have certain tests that measure all kinds of stuff before coming to such a conclusion. You know, smart stuff. 0 Quote Link to comment Share on other sites More sharing options...

How do they know it's H2O? Its not a liquid, its a solid (ice). It not only water and includes other substances like hydroxyls and hydroxides. Space probes can be equipped with spectrometers. These measure the different wavelengths of light being reflected of of solids and liquids, for gases they can measure absorption and emission spectra. We actually discovered the existence of helium from spectroscopes of the Sun before we found it on Earth. Anyway the light being reflected by these blocks of ice is in wavelengths consistent with the substances named above. 1 Quote Link to comment Share on other sites More sharing options...

The cost of getting a ton of anything into space is pretty big, mostly to get it past the Earths gravity and air resistance. Even with SpaceX its about $3000 per kg at the cheapest. If you have to lift the kgs of water from the Moon it takes something like 1/50th of the rocket fuel or something so much less fuel and in theory cheaper. Why 2024, well NASA has a mission for that year slotted for its new rocket the SLS, but only to go around the Moon. The current NASA chief reckons that by turning it into a Moon landing mission, you will only have one presidential election between now and then so both candidates will likely have to commit to such a short term project in an election and it will be much harder to kill it with the public. https://en.wikipedia.org/wiki/Artemis_3 Bezos seems to have gotten the contract for the lander, I new they were in the running but had not kept up to date.

There isn't a chance in hell they'll be ready by then without an Apollo style boost in funding. The SLS is years behind schedule and they haven't even awarded contracts for most of the other stuff yet. I'd be interested in your reasons for disagreeing rather than just a red dot. After all, I politely didn't mention your use of the word "gotten" on a Scottish football site.

Herman Hessian Posted November 3, 2019 Share Posted November 3, 2019 (edited) saw something for the first time ever this morning - a sun dog ! was very fucking cool, but had faded a bit by the time i got my shit together and grabbed the phone and some pics here's the technical bollocks from wikipedia - i'm amazed that there is confusion about the name - surely it's the same as 'fire dogs' - the sides of a big metal grate on either side of a fire, with the 'sun dogs' being either side of the sun; could only see one this morning though, t'other one was a bit too far round to the left...

So although it is a mountain, this would not be obvious if you were standing on it. Interesting that many examples are from moons and asteroids that lack the gravity to be more flat. I recall someone saying that if you adjust for scale the Earth is smoother than a billiard ball.
