Thanks, I was just searching for this! Believe landing is expected between 45 minutes from now and two hours from now, but I haven’t gotten the most up to date info.
Edit: Watching a moon landing be explained in Hindi while I battle a fever is proving to be a very pleasantly surreal experience.
Seeing that big EARTH COMMUNICATION: OFF is nerve racking at this point when it should have touched down.
Edit: I don't like the mood in the room.
Official announcement on whatever is going on should be soon. I caught something about receiving SSR data, but that doesn’t mean anything to me.
Edit: Possible theories just put out we’re that either the lander decided the first site wasn’t good enough and deviated to assess the second potential landing site, or a failure of some sort in the final period of deceleration.
Edit: Just stated that descent was as planned down to 2.1 kilometers altitude, then communication was lost. “Data is being analyzed.”

Flight director says they lost comms at roughly 2km but everything was within targets until then.
Hopefully just comms problems but unlikely. Still on the brighter side it's closer than the previous attempt by Israel, I think they got to about 10k before losing?

Seeing some reports on the twitters that the lander has been found and might have completed the descent? Nothing on any verified accounts (not that that counts for too much) or on the mission log yet though
Water vapor has been discovered in the atmosphere of a rocky exoplanet in the habitable zone of it's host star. The finding isn't yet peer reviewed, but this would be the first time water has been detected on a potentially habitable exoplanet. Don't get too excited though, they estimate the atmospheric pressure at the planet's surface would crush a puny, fleshy human. That doesn't mean other things couldn't live there, though.
Even though I've known about how it's done for a few years now, it still marvels me how much information we can glean about an object from dissecting its spectra.
Just like Teddy Roosevelt would have wanted. Another planet with things to fight.
Hopefully the pressure situation means they will be worthy opponents.
Just not too worthy. None of this "fair fight" nonsense.
Teddy Roosevelt was nuts, he'd probably demand to be dropped onto the planet with his horse even after numerous crushed egg demonstrations of what the pressure would do to him.
Shut up, Mr. Burton! You were not brought upon this world to get it!

"Well there's your problem, you're using EGGS when you should be using a MAN! With a HORSE!"
Scott Kelly retired from NASA in 2016, about a month after he returned to Earth and his body began to adjust. For some time, his legs felt jiggly, his joints ached, and his skin burned, unused to the touch of fabric, hugged close to him by gravity. Space, he said back then, had been disorienting. “Even after I’ve been here nearly a year, you don’t feel perfectly normal,” he said. “There’s always a lingering something you feel. It’s not necessarily uncomfortable, but it is a harsh environment.”

We really need to get a spinning ring habitat up and running. Before we go anywhere we're going to need one. Best to start testing now.
It is prohibitively expensive to get enough materials in space to make a large enough spinning habitat. I think you'd need more than the entire ISS and MIR combined.
Hopefully SpaceX will finally take launch costs out of the reasons not to do it.
The CFM wasn't for people (if a person got inside their head would be pulled in the opposite direction as their feet) but for experiment samples so control sets could be on the station and not the ground, eliminating any other environmental variables.

Oh, I know. I just thought it was the closest example to what @Lanz was asking about, since a mock-up/prototype was actually built, just never flown.
Perhaps the biggest hurdle to mankind’s expansion throughout the Solar System is the prohibitive
cost of escaping Earth’s gravitational pull. In its many forms the space elevator provides a way
to circumvent this cost, allowing payloads to traverse along a cable extending from Earth to orbit.
However, modern materials are not strong enough to build a cable capable of supporting its own
weight. In this work we present an alternative to the classic space elevator, within reach of modern
technology: The Spaceline. By extending a line, anchored on the moon, to deep within Earth’s gravity
well, we can construct a stable, traversable cable allowing free movement from the vicinity of Earth
to the Moon’s surface. With current materials, it is feasible to build a cable extending to close to
the height of geostationary orbit, allowing easy traversal and construction between the Earth and the
Moon.
Yeah, but I question its actual utility - once you're in orbit, the rest is easy.
The whole point of an (Earth) surface to orbit elevator is to get past the hard part. Which, no surprise, is hard no matter how you do it.

It would significantly cut fuel costs of reaching the moon.
"I will write your name in the ruin of them. I will paint you across history in the color of their blood."
Presumably it saves a lot of energy as the difference in energy requirements for LEO and translunar travel is a lot. So you'd use LEO capable rockets/the space line to transport much larger payloads way higher up the gravity well
Presumably it saves a lot of energy as the difference in energy requirements for LEO and translunar travel is a lot. So you'd use LEO capable rockets/the space line to transport much larger payloads way higher up the gravity well
It's about 14 km/s of delta V to go from the ground to GEO. It's another 4 km/s of delta V to go from GEO to the moons surface.
An elevator to go from GEO to the Moon would save energy, yes, but it's not a whole lot compared to what could be saved by taking an elevator from earth's surface to GEO.
Edit: Not to mention it is A LOT easier to gain V in space as compared to in atmosphere

Sure, but how much harder is it to build GEO -> lunar elevator than a surface -> GEO one?
Also, going from 18km/s total required to 14km/s is a significant reduction.
"I will write your name in the ruin of them. I will paint you across history in the color of their blood."
Yeah, even if the first couple hundred kilometers away from Florida are the roughest part, taking an axe to delta-V budgets anywhere else along the route is still savings.
Also remember you're not just lowering to-the-moon costs, you're lowering costs on the way back up as well. If travel between the moon and GEO is 'free' or close to it, you're getting into the realm of pretty significant savings on any kind of round trips.

And the moon is a much better target for asteroid drops too; lithobrake your target on the dark side, mine it there with the convenience of gravity, but not too much, ship it to the light side and Earth is much, much closer if there’s an elevator waiting for you.

I hope one of the lunar orbitor will be able to send back photos of their landing site.
