Best thing would be to terminate Artemis

Yeah, shit idea. And exactly why NASA gets shit on for consuming money with less to show for it.

Spend billions on a program set up by one administration, then some tool comes along and wants to cut costs because they want to look effective and cuts NASA’s programs. Program never completes, now it’s just a waste. NASA, being by default a scientific endeavor thar doesn’t need to return an profit other than exportation and research data, is an easy target. Billions invested and nothing to show for it. WhY iS NaSA So iNeFfeCtIve!?! Repeat for another program later.

kalkulat, w NASA rover discovers liquid water 'ripples' carved into Mars rock — and it could rewrite the Red Planet's history

Water scouring the surface? Or was it thousands years of wind-blown sand / dust? Dunes have ripples.

There is no water on Mars (not to be confused with liquid CO2) until somebody goes there and drinks some. Anything else is hoping for water to justify the $100billion price tag.

Read the article. This is from water that no longer exists on Mars.

DemBoSain, w Asteroid Ryugu samples suggest presence of salty water in outer solar system

Based on what we know about the universe, isn’t this pretty obvious? I’d rather see estimates for how much water?

FundMECFSResearch,

The big discovery was salty water, not water.

Hobbes, w Don’t panic, but an asteroid has a 1.9% chance of hitting Earth in 2032

Is there any way to get it here sooner?

DragonTypeWyvern, w Don’t panic, but an asteroid has a 1.9% chance of hitting Earth in 2032

Fucking finally goddamn

GrumpyDuckling, w Don’t panic, but an asteroid has a 1.9% chance of hitting Earth in 2032

I wonder if the “important” people know the chances are higher, so they’re going for broke in order to build their escape ship.

reddig33, w Astronomers just deleted an asteroid because it turned out to be Elon Musk’s Tesla Roadster

Yay more space garbage. Just what we needed!

atzanteol,

It’s in orbit around the Sun.

The point is that it’s nowhere near Earth to cause an issue like Kessler Syndrome, which the space junk comment is clearly referring to.

The car is space junk like every other test payload or probe we’ve ever sent out into space that we’ve lost contact with is space junk.

I don’t have any recommendations, unfortunately. But this is very interesting! I have gotten into software-defined radio recently and radio astronomy seems like a good direction to continue learning. Hopefully someone has some good advice.

Didros, w Astronomers discover repeating radio bursts from distant 'dead' galaxy

Do we know what we did with radio when it was first discovered to know what it would be like if it bounced back to us? Or would it not have been strong enough?

acockworkorange,

Quadratic decay plus reflection losses plus only a fraction of the emitted signal being reflected: pretty much guarantees we wouldn’t be picking it.
