I tried to match that image up with SpaceEngine and couldn't, but could that orange thing be a nebula? It doesn't seem to be a planet, based on where the planets currently are in Mars' sky, and you can't see the galactic centre from here because there's dust in the way.

Yeah, Perseverance said they had no plans to use the camera during the night. Temperature combined with low light means it would not be a benefit to use then.

It's a interesting concept. Sure, Mars has 40% of the gravity, but the atmosphere is only 1% (of the density, I'm guessing). That would actually make it relatively challenging to propel yourself on Mars using the atmosphere.CBC News posted:"Helicopters on Earth — as a reference — can fly, like 3,000 metres, 10,000 feet. And they don't usually fly that high, but it's about their capability," said Jim Reuter, NASA's associate administrator for space technology. "Flying ingenuity on Mars would be comparable to taking that full size helicopter and, instead of flying it 3,000 metres, flying it at 30,000 metres or 100,000 feet. And so Ingenuity has to be extremely light, relatively large [for its weight], and have fast rotor blades."

Yeah, enough to last an astronaut ten minutes. But hey, proof-of-concept. What they REALLY need is to be able to manufacture something like ten tons of oxygen as fuel for the trip home.

OMGVBFLOL posted:uh i think you mean as OXIDIZER?!? Yeah, you’re right, oxygen alone is not the fuel, it’s the oxidizer that reacts with hydrogen to produce thrust. It’s what I meant, but not what I said. e: I found out that a by-product of the oxygen production is carbon monoxide; in fact, two molecules of CO for every molecule of O2. Fortunately, it doesn’t have to be dumped into the atmosphere; it can be combined with hydrogen to make methane, which can in turn be used as a fuel.

interesting. where's the O go? does it get turned into water? or more O2?

The simplified reaction is 2 CO2 -> 2 CO + O2. So two carbon dioxide molecules yield two carbon monoxide molecules and one molecule of diatomic oxygen. The diatomic oxygen is captured and the carbon monoxide (for this proof-of-concept anyway) is returned to the atmosphere. Of course, for large-scale production, you don’t want to be dumping huge quantities of carbon monoxide back into Mars’ atmosphere. e: sorry, just realized you were talking about the leftover oxygen molecule from converting CO to CH4. I’ll have to look into that some more, but I did find that under certain conditions, you can combine a carbon monoxide molecule (CO) and two diatomic hydrogen molecules (2 H2) to make one molecule of methanol (CH3OH), which can also be used as a fuel.

Of course, for large-scale production, you don’t want to be dumping huge quantities of carbon monoxide back into Mars’ atmosphere. It'd probably be more straightforward to do a straight Sabatier reaction, using the carbon dioxide you sucked in from the Martian atmosphere and some hydrogen that you either brought with you or electrolyzed out of Martian ice: CO2 + 4H2 -> CH4 + 4H2O. Then electrolyze the water you get from it, save the O2 and put the hydrogen back in the tank for another go at making methane. At the end, you have methane and oxygen, ready to power a rocket engine. (This is the basis of the fuel-generation scheme used by the Mars Direct plan.)

that isn't too far off from what i remember the sky looking like in the high rockies, away from towns. and yeah it was dry as hell most of the time. i imagine it's even more brilliant in even higher, drier places like the himalayas. e: part of it might just be the nature of a camera vs naked eye; that's spot-on what a 30-sec exposure of the sky looked like even in town
