There's more. The triangulations would provide some really great confirmation and precision on a number of things.
The unanswered question is if this is blocked out from earth communication, what are you doing for earth communication? Moon satellites? Optical relays? Would it go to the Mars satellites? These things get booked so far ahead of time, you can probably pretty easily schedule the dark times when it couldn't talk to Mars especially if you send it up with modern storage tech.
I guess there's also Venus satellites coming around soon as well.
- gumby 4y agoWhy not put relay satellites that orbit the moon? Actually I think this is already being planned anyway, unrelated to a telescope.
- pixl97 4y agoThe moon is insanely hard to orbit because it's gravity is very lumpy https://www.nasa.gov/feature/does-anything-orbit-the-moon-we-asked-a-nasa-technologist https://www.nasa.gov/feature/does-anything-orbit-the-moon-we...

- asdfman123 4y agoFor close orbits, and far orbits are difficult because Earth’s gravity interferes—-to save others a click.
- dylan604 4y agowhat about some sort of Lagrange point orbit rather than orbiting the moon itself?
- asdfman123 4y agoLagrange point orbits are unstable as well. It all can be done but takes propellant.
- kristopolous 4y agothe moon is after all just a bunch of collision dust. It's a weird thing. https://www.youtube.com/watch?v=kRlhlCWplqk https://www.youtube.com/watch?v=kRlhlCWplqk
- SoftTalker 4y agoWhat's really cool about CAPSTONE is that it's the first spacecraft to test the entrance and sustainability of a very unique near rectilinear halo orbit, also known as NRHO. This NRHO orbit is at a precise balance point between the gravities of the Earth and the Moon, which offers a long, stable orbit so that Gateway and future spacecraft don't have to carry so much fuel to stay in orbit around the Moon. So that implies that in the Apollo missions, the command module had to burn fuel to stay in orbit around the moon? And I guess if anything had delayed the landing module from its scheduled return, the command module might have run out of fuel and been forced to abandon the astronauts on the moon?
- whatshisface 4y agoThe command module orbited fewer times than a satellite would have to.
- OkayPhysicist 4y agoIt would probably be cheaper to put several relay satellites in extra-lunar orbits around Earth. Earth's gravity has a tendency to complicate lunar orbits.
- nealabq 4y agoOr put a relay in a halo orbit at earth-moon L2. Or at the earth-moon L4 and L5 orbits, which would cover a good portion of the moon's far side.
- jwuphysics 4y agoSatellites are also one of the biggest sources of radio frequency interference. (I did my PhD in radio astronomy and currently work on multiwavelength astronomy.)
- zokier 4y agoThere is no shortage of lunar communication satellite projects. ESA has Moonlight/Pathfinder, NASA has LCRNS/LunaNet, CNCA has its own projects (e.g. Queqiao), and there are even private efforts.
- dflock 4y agoI'd just run a bundle of optical fibre cables over the horizon to the nearside and transmit to earth from there?
