  • For sure, and that can definitely work. But, you will need three times the number of solar panels (since half the time the panels are doing nothing and if you’re storing a lot of energy, that means there’s a proportional amount of storage losses.)

    And I honestly don’t know how much mass in batteries would be needed for 15 days worth of storage, but my instincts say too much.

    Keep in mind that total mass to deliver can sometimes be a biggest cost limitation. A nuclear generator that gets delivered in one launch could be cheaper than otherwise much simpler solar panels and batteries if that solution requires two or three launches.









  • So… The US has plans to build nuclear generators on the moon too, kilopower has been an ongoing project for the past decade and I have no doubt we’ll be ready to deploy one of these reactors as soon as we start building infrastructure on the moon again in the near future.

    Nuclear power is not new for space, it’s an obvious choice, one of only two choices in fact. And for what it’s worth, Russia/USSR has had far more nuclear powered space probes over the years than the US has, so this isn’t exactly new for them either.

    As for cooling, yeah, if you generate power you need to dissipate that heat. Your generator will put out heat which needs to be dealt with and then using that electricity will also generate heat which needs to be dissipated. That said, one kind of power is not harder than another, dissipating a megawatt of solar power is just as complicated as a megawatt of nuclear. So the real question is: how much power do you need? The complexity of the project will scale relative to that.

    All in all, we’ve used nuclear power in space before and we will need to do it again, radiators are not all that hard.







  • It’s disappointing to see so many posts from outraged users railing about the dangers of automation, who clearly haven’t read the article and don’t seem to understand what actually happened.

    This story is actually what it purports to be, it’s an example of a safety system working correctly in an emergency. That’s all it is, not all that exciting to be honest. There was no bug or accidental activation, or AI uprising.

    The only weird part is that the pilots could have landed themselves if they had wanted to, but chose not to. If there were any passengers on board that would have certainly been called a criminally reckless choice. As it was just the pilots though, I suppose it was just bold/dangerous/dumb. (Though on the other hand, they learned more about their aircraft in the process and they tested a critical safety feature, which are both good things.)



  • This falls in the same category as the MCAS crashes. An automated system wrested control from the pilots, and the system evidently could not be disabled. That is the exact scenario that caused the MCAS crashes.

    The only thing though, is that is absolutely not what happened here, at all.

    Here’s a quote from the (quite short) article:

    Autoland “automatically engaged exactly as designed when the cabin altitude exceeded the prescribed safe levels” and the pilots “made the decision to leave the system engaged,” Townsley said

    The pilots saw the warnings and presumably could have taken over by doing just about anything, but with no passengers to put in jeopardy, they decided to sit back and see what happened.

    There is no flaw here, no bug, this is not a problem. This is what happens when everything works.

    Edit: Well, not everything was working, that beechcraft does have to have its pressurization system checked out for sure.
