Submission + - trump proposes nasa budget be slashed by 23% (arstechnica.com)

Can we stop pretending that America is still stuck in the 1960's? The overwhelming majority of Americans no longer have a Jim Crow mindset, and no longer regard as remarkable when a woman or "person of color" (i.e., an ordinary person) does something that white people have been doing for years. Diversity is ordinary now, and has been for the past few decades.
Diversity is like a religion with some people - no matter how much you (Americans) repent, you are still a sinner and in need of grace and forgiveness from TPB.
A growing number of employers are using surveillance wages to negotiate your next paycheck.
Still nothing to hide?

Way to say your dealers suck.
Simplify. The best part is no part. The parts omitted never fail. They don't require maintenance, supply chains, continuous improvement.
The Moon is target practice. We need to get away from innovative bespoke engineering, into industrial mass production with continuous improvement. To do that we need to fly often. Mars just doesn't have the launch window availability. The biggest part of the challenge is that we were born in the bottom of a deep well. To toss enough stuff out of the well for a long journey is critical. Boosters that reliably fly on time often and cheaply enough to get ships and fuel out of the well. Ships that carry fuel into orbit and return over and over since the vast majority of the material we need to send out of the well isn't payloads or ships, it's fuel. Kilotons of fuel. Once the factories and processes are set up for that going far beyond the Moon is fairly easy. But with a narrow opportunity every two years that's not going to happen in a human lifespan. It's not enough refinement cycles per year.
I see this accelerating the Mars objective, not deferring it.
But probably not all that great for long hauling. Though I believe there is an easy solution. A small second trailer shaped like a cone for aerodynamics that is full of battery and is connected by cable to the semi. Then for long hauling you simply stop off at a depot and drop off the batter trailer and hook up a charged one.
This is the first step toward adjustable prices. Weather is hot, all cold beverages are 25 cents more. Snowstorm en route, snow shovels are now $40.00 instead of $25.00. It is price on demand.
Because our executives are too dumb to come up with a new idea for you to work on.
Executives should be prevented from receiving bonuses any year in which there are mass layoffs.
Then they leave only violence as a recourse. There needs to be a legal recourse. Otherwise, those who suffer the consequences (e.g. black lung, asbestos, who knows what from the thousands of pesticides, etc). Then victims with no legal recourse will be left to resort to illegal recourse and violence.
This is the crux. Optimization of supply chains to eliminate inventory makes them frail. Or, to quote Wirth:
Premature optimization is the root of all evil.
The last of the US federal helium reserve - including land and equipment - was sold in 2024.
Is joke of course. Was angling for the same joke.
3He is normal helium atom with an extra neutron, hoped to be used in some forms of fusion. It's not considered radioactive. Emitted by the sun it's trapped in lunar rock possibly at concentrations of up to 50 parts per billion but more likely 5-10ppb. The utility of extracting it from the Moon is hotly debated. On Earth isolating it from normal helium involves the same sort of centrifuge used to isolate isotopes of uranium, radium, hydrogen but there is far less of it than in lunar soil.
This is not actually the case in the subject at hand. It's all normal helium. When cooled enough all other gases will precipitate out as they freeze - including Hydrogen - leaving only helium as a gas and so easily isolated. That's actually why it's valuable since it's the only gas that will boil off at temperatures so low that the conductors immersed in the fluid will superconduct supporting the currents necessary for the intense electromagnets used in imaging and such.
