It’s because they can claim “oh that sat will only be up for two years so we better get another one funded and up there quick!”

Nothing to do with how much they “miss” they just want money, which is how all American companies work. Spend it or lose it.

Yeah, I get that. This is such a minor “complaint” (not complaining) but it’s weird how much they miss by

I don’t know how long time it would take to return to normal. The flaring event itself is short lived, a few hours give or take. Probably decades for everything to be back to normal afterwards though

How long would that last?

Things like life expectancy are minimums. As long as it exceeds the minimum, it 100% meets the requirements.

OK, I have a weird hill to die. This isn’t a complaint, but more a curiosity.

NASA claims all these satellites, telescopes, rovers are suppose to last 2 years and they end up lasting decades. How can agency so reliant on precision miss on life expectancy?

I get they’re missing on the right side of it and that’s 100% a positive, but still. If they said it should last 15 years and it last 17, I get it…but man they miss by a lot.

Hello u/Bigg_Dick_Energy, your submission "What sceicne experiements can the artemis program do that cant be done here?" has been removed from r/space because:

One of the goals of Artemis is discovery, measurement, and experiments with lunar surface materials like ice in polar craters. Lunar surface materials are, by definition, on the moon, not Earth.

Radiation is a big one. Earths magnetic field shields a lot on the ISS.

It's also about finding the things we don't know yet.

As for benefits of sending people. All of this has to be planned and constructed. People do that do get paid. The Apollo program for example returned $7 for each dollar invested: https://space.nss.org/settlement/nasa/spaceresvol4/newspace3.html

> Compared with other forms of investment, the return is outstanding: A payback of $7 or 8 for every $1 invested over a period of a decade or so has been calculated for the Apollo Program, which at its peak accounted for a mere 4 percent of the Federal budget. It has been further estimated that, because of the potential for technology transfer and spinoff industries, every $1 spent on basic research in space today will generate $40 worth of economic growth on Earth.

Some new tech will have to be developed which will be useful here on earth. So forth and so on.

The "problem" is that it doesn't benefit singular investors but society at large. So private companies won't finance programs at such a scale and you need to do some thinking to see how those benefits flow back into your pocket.

Effects of radiation. While exposure rates are higher on the ISS than the ground, the rate in space, the Moon, or Mars is much higher. It's also much different than we can test on Earth.

If we plan know sending humans farther than LEO than we Need to study this. But if their argument is we shouldn't send people, then there's really no answer as to why the program is a necessity.imo

Well for starters it’s a lot easier to study the lunar surface when you’re on the lunar surface

The ISS will likely be getting decommissioned by the end of the decade so there will be need for a new space station. The lunar gateway, which is part of Artemis, is that replacement

Ahh yes, when people didn't think global warming was a political issue. What refreshing times.

That's interesting how gravity influences biology?! Certainly our vascular system and bone structure are evolved to work against it,..

but we can already test no gravity experiments on the ISS...

Certainly any experiments around how earth's gravity influences biology, materials, etc. Artemis can test the effects of both zero gravity in space and low gravity on the Moon and Mars.

Well obviously it did if they were hit by one.

For sure. Back in may or June or 2021 a catastrophically large solar flare erupted, and Earth was like 7 days away in its orbit from getting hit

Had we been hit, basically half of the planet would have entered the pre electric era overnight

That sounds amazing, can't wait till it's done.

truly believe our satellites could all go down at anytime due to events like this if it was major enough.

I was lucky enough to witness that burn-up in NW WA! Coolest thing I’ve ever seen.

No it doesn't...these are calculated and predictable events.

Here is a picture someone caught of it. Pretty cool how it looks like a rocket taking off. https://i.imgur.com/L5Uanps.jpg
