Comment Re:Why do we need a giant publicly funded moon bas (Score 1) 82

Hell of an assumption considering which company volunteered to retrieve astronauts from the ISS after "only" another rocket company failed to do so.

Not sure what you mean by "volunteered". SpaceX was paid to retrieve the astronauts, which they did as part of their contracted flights to the space station.

True.

SpaceX's recent successes tend to make people forget that the company started out with three failures in their first three attempts to launch their first rocket, the Falcon-1. (And, for that matter, SpaceX also had it's share of explosions on the pad during a static fire.)

Yeah: space is hard.

Comment Re:We may have altered the plan. (Score 2) 82

I'm not an expert on rebuilding massively exploded launch infrastructure; but I have a suspicion that a 2026-2029 plan is now going to involve less Blue Origin than previously believed.

Ars Technica has an article discussing how this is a major setback in the NASA lunar plan: https://arstechnica.com/space/...

Comment Rocket-powered drones (Score 1) 82

Only thing I can think of is they will use tiny rockets or air jets in place of propellors...

Right, these are rocket-powered drones.

That means their total flight time will be limited by the amount of fuel they start with, but it should be enough to hop around to multiple sites, including (I'll hope) sites too uneven to land a large lunar lander.

Comment This is how science is done [Re:Good] (Score 2) 65

Dark energy and matter are not explanations. They're the names given to the problems of discrepancies between model and measurements.

More explicitly, they are names given to a proposed solution to the problem of discrepancies between models and measurements. Measurements show that objects in the universe move in a way that isn't fully accounted for by the gravity of all the things that we can see (that is, the stuff emitting or reflecting light), so the proposed explanation is that the discrepancy in motion is due to the gravity of things that isn't emitting or reflecting light.

This is a hypothesis. It fits the facts we have so far. We still have to find evidence that the hypothesis is correct, or that the hypothesis is wrong. That's how science is done. You come up with a hypothesis that fits the measurements you have, then you look for ways to see if the hypothesis is correct.

Comment The geothermal plant already exists [Re:MS Pow...] (Score 1) 88

The summary says that this thing is supposed to be geothermal powered. So they just have the cart before the horse here. They need to set up the geothermal power plant first, then build the datacenter after the power plant is operational.

The geothermal plant already exists: https://www.globalelectricity....

Apparently, Microsoft was proposing to build the data center there and tap into the existing geothermal power, not build new geothermal power (the summary was a little confusing about that).

Comment Re:Ketamine [Re:So, nothing really new here] (Score 1) 44

Usage rules mandate that the drug cannot be taken at home.

This part is incorrect. Many schedule 3 drugs are taken at home, legally. Ketamine in particular has no special statute governing it, and there are at-home therapy programs.

That was a quote pasted directly from the Psychology Today article linked, but a quick google shows you're right, no support for that statement. Possibly the phrase "usage rules" (PT's phrase, not mine) meant recommended practice (at the time the article was written) and is not legally binding.

That being said- absofuckinglutely your ability to make rational, correct decisions is ridiculously disrupted on ketamine.

Comment Ketamine [Re:So, nothing really new here] (Score 4, Informative) 44

Ketamine is a very commonly prescribed drug, especially over the last decade for treating PTSD. I don't know what that has to do with nazis, nor do I see any good coming from stigmatizing it. What other medicine do you like to stigmatize? Vaccines?

Ketamine is a Schedule III controlled substance: having accepted medical benefits but abuse potential. Usage rules mandate that the drug cannot be taken at home. Patients are observed at least two hours after receiving the agent and typically receive psychotherapy and other treatments for depression.

https://www.psychologytoday.co...

Quoting Gerard Sanacora, M.D., Ph.D. Director of the Yale Depression Research Program and Co-Director of Yale’s interventional psychiatry program: “Large amounts of data suggest that your ability to make rational, correct decisions is completely disrupted when you take ketamine, as long as it’s in your system... People can hear things, see things, feel things differently. The physiological and psychological reasons are the main reasons the FDA declared Spravato [Ketamine] safe only in a health care facility under supervision.”

Comment Re: How does this compare (Score 2) 43

That's what I am trying to figure out, the best I can think of is the albedo effect but microplastics is way to small to have that effect,

Yes, it's the albedo, and also yes, too small to have a significant effect compared to the main driver, the greenhouse effect..
The summary actually states this:

If the latest estimates are right, Shindell said, microplastics might not be an enormous source of atmospheric warming, compared with massive contributors such as cars and trucks, belching industrial plants or even burping cows.

But then undercuts that with

"But not a trivial one, either," he said.

Spoiler: yes, it's trivial.
