> No. Let's first feed the homeless and struggling, and fix the crisis that are affecting ordinary people.

I may be wrong, but it's not money that's the problem; there's plenty of money. (I would also point out the NASA budget is a miniscule spec of dust compared to the total budget.)

It seems to me the problem is organization and politics - actually doing the right things to address these problems.

It's like, say, Microsoft. They can't run a successful project to save their lives. This is an organizational and cultural problem. Large organization, lots of politics, enough money that success or failure is not critical to survival.

> Governments should have been able to do that up until now. Instead the government has been shipping money overseas and spending it on foreigners for far too long.

In what ways?

the government that slashes your science budget is the same government that would never feed the homeless, unless it was -to the sharks.

Supposedly, the Senate Launch System boondoggle is being killed, but not until 2027, by which time the Artemis III moon landing is supposed to happen. Since Artemis II (manned flight around the moon) has been delayed again, that's unlikely.

Ninth Space-X Starship/Super Heavy launch some time this month.

"Venus is dry" I thought the Venus theory was runaway greenhouse driven initially by water vapor. Going off memory, H2O is roughly 10 times as effective a greenhouse gas as CO2, with Venus being closer to the sun A larger percentage of water ended up in vapor form, leading to a feed back loop where the increased heat pushes more water to vapor leading to more heat, eventually liberating the co2 from the rock, making…

From your link: > Lighter gases, including water vapour, are continuously blown away by the solar wind through the induced magnetotail. There used to be a lot of water on Venus.

Moreover, I think Venus has lost most of its hydrogen to space, so you can't even make water anymore. Hydrogen escapes the atmosphere relatively easily for Earth- and Venus-sized planets[1], and the vaporization of all the water and subsequent disassociation[2] of H2O allowed the hydrogen to escape into space.

What is the Trump administration doing to feed the homeless and struggling?

Programs like SNAP benefits (a.k.a. food stamps) have always been top of the list of what Republicans want to cut.

Where can I contribute to put all the senators in a spaceship and yeet them into outer space?

Venus is a damned shame. Had planetary evolution gone just slightly differently, the solar system could have had two habitable water planets. Mars, owing to its size, was never going to cut it, but Venus might have.

Crazy factoid one: The Earth masses more than everything else between the Sun and Jupiter combined. Crazy factoid two: Venus is 80% of the Earth's mass.

It also blows my mind that the Sun accounts for 99.86% of the entire Solar System’s mass.

I would remind everyone that congress sets the budget. This is merely a proposal from the president. The proposal is regularly ignored. Nothing has been cancelled, yet, merely proposed to be cancelled.
