I think the only one that can solve all of their problems is elon. He would fix it in few weeks. Include him in next launch, he will troubleshoot directly on the Moon. Please, someone, send that asshole to space.

[–] roofuskit@lemmy.world 57 points 3 days ago (1 children)

And he's so full of hot air he doesn't even need a suit.

[–] kokesh@lemmy.world 17 points 2 days ago (3 children)

He would try to smoke the moon regolith and come up with some rad ideas. Occupy Moon! Yeeeeaah

[–] Thrashy@lemmy.world 9 points 2 days ago

Elon in his Cave Johnson era and we're here for it

[–] roofuskit@lemmy.world 4 points 2 days ago

That would be awesome. It's pretty much super asbestos.

I'd like to share a design concept with IM given that this is their second moon topple:

[–] Cocodapuf@lemmy.world 5 points 2 days ago

I mean, you're not wrong. A low center of mass is legitimately a good idea.

Weebles wobble, but they don't fall down!

[–] Uniquitous@lemmy.one 43 points 3 days ago* (last edited 3 days ago) (1 children)

The first one fell over and sank into the ~~swamp~~ crater.

[–] makyo@lemmy.world 21 points 2 days ago (1 children)

Sooooo we built another one

[–] Cavemanfreak@lemm.ee 23 points 2 days ago (1 children)

That sank into a crater. So we built a third one. That burned down, fell over, and then sank into a crater. But the fourth one stayed up. And that's what you're going to get, Lad, the strongest spacecraft on all of the Moon.

- Not to leave the room... even if you come and get him.
No, no. Until I come and get him.

No, no, no... etc.

Breaking news, space is really really hard

[–] VonReposti@feddit.dk 16 points 2 days ago* (last edited 2 days ago) (1 children)

It's not space that's hard. It's the stuff you encounter when you run out of space that's hard.

[–] Lemminary@lemmy.world 3 points 2 days ago

Like when you run into me bc I'm hard 4 u bb. ( ͡° ͜ʖ ͡°)

[–] MonkderVierte@lemmy.ml 3 points 2 days ago

A hard void.

[–] over_clox@lemmy.world 25 points 3 days ago (3 children)

Well that's a facepalm of a faceplant 😂

You'd almost think that by now they might have learned something from the Voyager 1 and 2 power systems and not relied completely on solar power...

[–] Badabinski@kbin.earth 33 points 3 days ago (1 children)

The biggest problem with RTGs is the extreme cost and lack of availability. Pu-238 is very expensive and at any moment, there's only tens of KG of Pu-238 available for RTG use. They're not really a reasonable choice for private industry at this time.

[–] over_clox@lemmy.world 5 points 3 days ago (1 children)

As true as that is, they said that it cost them hundreds of millions of dollars, and the mission was only planned to last from 10 to 14 days or so. They could have used just a piece of a waste uranium rod or something as an alternate power source for such a short-lived mission.

I mean yeah, of course that would still add to the cost and complexity, and I don't even know what all that would take, but hell if you're already into the hundreds of millions of dollars range, you ought to consider redundancy and alternate power sources.

[–] Badabinski@kbin.earth 18 points 3 days ago

I imagine it's more complicated than that. For example, Pu-238 only emits alpha radiation. I doubt that reactor waste only emits alpha radiation, meaning you'd have to harden the electronics for a close and potentially extreme emitter of beta/gamma radiation. I also don't know if random high grade reactor waste gets hot enough to provide meaningful amounts of energy via thermoelectric means. Alternatively, it may be that it gets too hot.

I doubt they could have simply slapped something together. The cost of developing a new RTG capable of using reactor waste would likely be a significant fraction of the budget to develop the probe itself. It might have been worth it, but I feel that it's not clear-cut.

[–] Maeve@kbin.earth 8 points 3 days ago

They also used the same design of a prior craft that met the same fate. But private industry are problem solvers. 🙄

[–] Cocodapuf@lemmy.world 7 points 2 days ago (1 children)

Eh... I think they should stick to solar power. Given how much trouble they've been having, let's not give them any weapons grade isotopes...

For what it's worth, just last week, Firefly stuck the landIng on their first attempt. They're seriously killing it these days, I'm happy for them.

[–] over_clox@lemmy.world 4 points 2 days ago (8 children)

Solar power? On the south pole of the moon?

That would just barely work on its own, even if the thing didn't topple over.

[–] Cocodapuf@lemmy.world 3 points 2 days ago* (last edited 2 days ago) (1 children)

Would it barely work, or would it always work?

If you plan to land on the pole, at a high altitude, you could potentially have direct line of sight to the sun 24/7 all year round. From the ground, the sun would appear to travel left to right along the horizon, making a full circle over the course of a month. You just need your solar panels pointed to the sides, not up.

However, if they aren't directly on the pole, they could still plan their landing to be in a location that gets sunlight for 15 earth days straight, with 0 interruption. As that might be more than the necessary time period for their experiments, that's probably perfect. And that doesn't even require being at a high elevation.

Also, being on the pole doesn't result in dimmer sunlight than on the equator like it would on earth. No atmosphere means the poles get the same completely unfiltered sunlight.

Look, the vast majority of lunar landers (and there have been quite a few) have used solar power, it's the obvious choice in space.

[–] over_clox@lemmy.world 3 points 2 days ago* (last edited 2 days ago) (1 children)

Nah, solar is the obvious choice in space near the sun, and by not borking it up by landing sideways in a crater on the south pole of the moon.

Very limited scope for solar power, it don't work after landing sideways in a crater on the south pole.

Edit: By the way, our next lunar eclipse is in 6 days, do you really think that thing would go uninterrupted, even if it did land correctly?

When one day we get people back on the moon, is there a chance these devices could be brought back online?

[–] gibmiser@lemmy.world 5 points 2 days ago (1 children)

More likely salvaged as part of a permanent moon base.

[–] bamboo@lemmy.blahaj.zone 6 points 2 days ago* (last edited 2 days ago)

This was a plot point in The Martian which was pretty neat. There was also an episode of Futurama which was also neat

[–] x00z@lemmy.world 4 points 2 days ago

Brought back*

No need for this trash on the moon, even if it works.

[–] Cocodapuf@lemmy.world 3 points 2 days ago (1 children)

Well, if we have boots on the moon, at that point we don't need probes like these. At that point you just drop a sensor, or whatever experiment you want directly on the surface.

[–] veeesix@lemmy.ca 2 points 2 days ago (1 children)

I was looking at it from the perspective of all the failed probes we’ve sent and whether or not the lost costs/missions could be recouped or completed somehow.

[–] snugglesthefalse@sh.itjust.works 4 points 2 days ago (1 children)

Depends on how long it sits there, the lunar surface has a pretty wide range of temperatures that cause wear, lots of radiation and the regolith is quite abrasive. But realistically by the time something gets there that could put it back it'll probably not be worth it from anything but a historical standpoint.

Whoopsi-doodles. Well, more spare parts on the Moon, all the same.

Landing a fridge on those spindly little legs did seem a bit... optimistic...

[–] Cocodapuf@lemmy.world 4 points 2 days ago* (last edited 2 days ago)

I really don't understand the tall moon lander strategy... I mean, if you're going to design it with a high center of gravity, then design it to fall over... Just use two landing legs instead of four, to ensure it falls over the right way. Then you put the solar panels on the side, so that when it topples over they're facing up.

I've literally done this in Kerbal space program, it's a pretty reliable landing system if your probe is tall.

[–] Talaraine@fedia.io 6 points 3 days ago

Seems Firefly Aerospace has got this all sorted, though. Amazing feat for them last week to have a flawless landing.

[–] Rhaedas@fedia.io 6 points 3 days ago (1 children)

This could have potentially happened to Apollo 11, had Armstrong not taken over manually to steer clear of the targeted landing site with some rough areas. Maybe it would have been just leaning and not a big deal, but at the time we had no clear idea what a real landing would end up like. And I would hazard a guess that even though we've done a lot over the decades, the polar regions of the Moon are still pretty unknown.

…but at the time we had no clear idea what a real landing would end up like…
