And when all of that runs out, then what?
We are already seeing its effects on places like El Salvador. People leaving there and coming here because they can't raise crops.
I did hear an interesting story on today's NPR's Here and Now and indoor farming.

Brown Dwarfs are essentially high mass gas giants though. That's the issue, we don't have enough knowledge about them and the limit to which they transition to stars to properly classify them better. They are difficult to find and observe because they don't shine bright comparatively and we only have hypothetical limits to what mass is necessary to ignite.
But yes, lower end mass gas giants like what is in our solar system are definitely not close enough to be considered failed stars in any regard.

Raptor isn't doing that fine. You had many failing during starship's fights (not always the engine fault, but still) and 2 failing in the latest static fire. IIRC it also started development before the BE-4 (well before if you count when it was still supposed to burn hydrogen, but not much development was happening then). And let's not talk about deadlines, we all know that in the space industry they are just optimistic targets.
The RD-180 is a Russian engine, they have experience with oxygen-rich stage combustion, not the USA. AFAIK BE-4 will be the first oxygen-rich staged combustion engine made in USA to be flown (if we ignore that a full flow staged combustion engine also has an oxygen-rich side).

Asking AI to tell us what sentience sounds like. Scary.

Thanks for this.
I'm going to have a look in the app now.

I did hear rumblings about inefficient management being related to why Bezos quit Amazon to be more involved in BO.

According to Google, Venus, Mars, Jupiter and Uranus are visible in the UK sky tonight, (insert Uranus joke here).

Download skymap from the app store and then just point your camera at them but that being said, if there are 2 "stars" vastly brighter than all of the others, they are likely not stars at all, they will most probably be planets.

Fairly close together? Jupiter and Venus are both brightly visible and to the west at the moment

If they're near the moon it will be Venus and Jupiter

I was going to say, white dwarf stars are very small (on the scale of space) but still have a good portion of their prior mass. It's very reasonable to assume that a planet could form around it, even if improbable.

Every astronomy enthusiast gets mad when you call gas giants a failed star. That's like saying an asteroid is a failed planet. It is what it is and has an important place in our universe.

Probably something about how stars need mass for something to orbit it or something. I'm not a expert.

“Though on average this class of stars hosts more planets around them than other star types, it was previously believed that their formation makes them unlikely to be orbited by gas giants. The discovery of this exoplanet — designated TOI 5205b — by astronomers using NASA's Transiting Exoplanet Survey Satellite (TESS) telescope challenges that concept.”

I think there was some talk about BO trying to renegotiate a better deal for the engines or something? Take with a large table spoon of salt because I think I'd heard it on reddit.

You've hit the nail right on the head in your response. What we need to do is get water to El Salvador. If you don't want people leaving El Salvador, it is much much much much much much much much easier and cheaper to get water from the Atlantic Ocean or the pacific Ocean or even the Indian Ocean or the Arctic Ocean, desalinate it, and pipe it or ship it to El Salvador then it could ever be to get that water from a planet hundreds of millions of miles away. The water on earth isn't disappearing or running out. It just moves around. There's no place for it to go other than somewhere else on the planet. Solutions like urban indoor farming, reduce water consumption locally and have a role in solving this problem. But trying to build some sort of infrastructure to transport trillions and trillions and trillions of gallons of water over months or years long journeys from other planets do not. I'm not understanding where you're coming from. You have a solution in search of a problem, and honestly, it's not much of a solution.
