Or maybe the advantage is not having to counter any sail movement with gyroscopes... which cost energy too.
I think you nailed it right there.
And they're doing a real bang up job of it... Dropping tanks of Nitrogen Tetroxide and hydrazine to explode near towns. Really killing it.
And you should know, China is not doing it themselves, there are about a dozen launch companies and aerospace manufacturers making rockets in China.
The Long March 2C that carelessly drops its booster all over the place (a poorly designed rocket) is government made, but they aren't all that way.
Private companies have always been a big part of space flight, except it used to be only large defense contractors (Aka, Boeing, Raytheon, lockheed, etc). Honestly the situation is better now than it has ever been. But we'll never get all private companies out of space flight, NASA can't do it all themselves.
You would think that, but that's probably not the case. This is what they train for, this is what they want to do. As a rule, astronauts don't tend to get bored of space, that's why they're astronauts.
Maybe we should just make those AI tools public and free and leave it at that. If you monsters want kiddie porn, have this AI generated stuff. It's sort of like having needle exchanges or safe using centers for addicts. It doesn't solve the problem, but it makes it safer for everyone.
Why isn't it targeted at the entire fanbase?
Is that a serious question? Because the answer is obvious...
Ok, let me start out by saying I have an 8 year old, and he fucking loves Minecraft. And hey, I played the game a bunch back when it was in beta and I was like 25. But I did not love the game the way that he loves the game... He's obsessive about Minecraft, some days it's all he talks about. How many adults do you know like that?
And here's the real question, when's the last time you bought Minecraft merch for yourself? Because my kid has a Minecraft lunchbox, a Minecraft hoody, a Minecraft Lego set, some Minecraft figurines, and of course the Minecraft sheets and PJs.
Nice reference!
That's such a badass design, I love it.
A variable thrust and thrust vectoring propulsion system with no moving parts. I doubt that's ever been done before...
Maybe someone can answer me this: I've always wondered if a solar sail can only generate momentum away from the sun or if it can be angled to create momentum in other direction.
Yeah, 100%. You can totally steer and control your orientation with a solar sail. This is one of the rare actually intuitive things when it comes to spaceflight. (with physics in space It seems like nothing actually works the way you'd expect it to, but this basically does)
We actually have some experience controlling orientation with "solar sails" too. I remember one example of a spacecraft which long after finishing its official mission was left to tumble out of control. Years later, some engineers were able to regain control, use the last of its propellant to counter its tumble and then keep it oriented correctly using only its solar panels as sails, light pressure was carefully controlled to keep the spacecraft oriented.
Ok, a side note on etiquette here.
When I saw this reply it had a point score of 0, which means somebody downvoted the post.
When a user is freely admitting a lack of expertise, and defers to another user who seems to know better, I would say it's extremely rude to downvote that reply.
This is an example of a user going out of their way to humbly rescind their previous statements when it appears they were mistaken (this is admirable and not a thing that usually happens on the Internet). They didn't do it for their own benefit, but for the benefit of the community, to not leave misleading or incorrect information in the comments.
So to sum up, downvoting a selfless act is pretty shitty and not good for the community.
Well, we have multiple launch vehicles, we have multiple crew capsules, multiple cargo vehicles, and just about all of them are cheaper than our previous options. The crew capsules we're using now are all several orders of magnitude safer than the space shuttle (even the Starliner in it's current state is an order of magnitude safer than the shuttle). And now we have options that don't require us to negotiate with Russia to use them.
