Nice job!!! always nice when assets make killer money
But is there silver on the Moon, or in the asteroids? And would it repay the cost of mining and shipping?
The Lunar astronauts had to deal with all the same things -- the only difference is length of time, and astronauts have put in long times on the International Space Station.
I'm not so sure about that. People have lined up to become test subjects for life in space. I don't remember if the tv show mission was to prep people for the Moon or Mars. But there are enough people out there who would sign up to live in a can so I'm not worried about finding people to populate
sadly, there isn't enough silver on the moon to make it profitable (from what we know today)
we need some major breakthroughs. I think it will happen, we just have to learn the math
Well, we'll see now whether RW confidence in the creativity of private-sector competition is well-founded.
Some materials will clearly need to be brought back to earth, where some materials will be used to create/expand the space station and to build new space ships. To make this feasible, we will need to create a space elevator. Once we have a working elevator this project becomes very profitable
Is anyone even working on that?
Think as we get back to being serious about space that these problems will fall one by oneThat’s a fun thought experiment, but we’re a long way from warp drives. Sure, gravity can bend light, and general relativity lets massive objects warp spacetime, but turning that into a “seconds-long trip to Mars” isn’t just a technology problem; it’s physics as we currently understand it. We’d need energy on a scale that makes the Sun look like a nightlight and materials that don’t exist. Until then, Mars is still a multi-month slog through radiation, microgravity, and life-support logistics, and the physical limitations of the human body.
There are only three real problems getting to Mars: Shielding the crew from cosmic rays for an unprecedented length of time (not a problem in the ISS because it's inside the Van Allen Belt, but Mars has no magnetic field, nor does interplanetary space); staying on board the ship for at least a year; and designing a ship that can carry enough fuel for a return trip.
200 lbs on Earth is 76 lbs on Mars. Astronauts on Mars for two years and after a months-long return to Earth would suffer detrimental harm the human body. In low gravity, bones don’t bear normal loads. The body says, “Guess we don’t need this much skeleton,” and starts reclaiming calcium. Astronauts on the ISS lose about 1–2% bone density per month, even with exercise. Over two years, that’s a serious loss, especially in hips, spine, and legs. Returning to Earth would mean fragile, degraded bones suddenly having to support full weight again. Standing up on Earth would feel like wearing a 200-pound backpack; walking without assistance would be difficult. We haven't even gotten into cardiovascular deconditioning, effects on the vestibular system, and galactic cosmic radiation exposure.
What makes you think we are going to 'get back to being serious about space'? We are more likely to decrease our investments in space than we are to increase them. I don't see NASA getting any major budget increases any time soon.
Factually accurate, but marred by the glitchiness of all AI slop. The real Richard Feynman would never call the Saturn V rocket “ Saturn the Fifth”
The physics are correct.
The materials necessary to build a space elevator have not yet been invented.
Can you provide an example of converting water to rocket fuel at scale? Being able to make tiny amounts in theory is useless.As usual, you’re confident while completely blinded by your lack of knowledge.
"In situ resource utilization.”
"You wouldn't need a backhoe to dig up this ice. You could use a shovel," said the paper's lead author, Sylvain Piqueux of NASA's Jet Propulsion Laboratory in Pasadena, California. "We're continuing to collect data on buried ice on Mars, zeroing in on the best places for astronauts to land."
Clue for you: H2O is raw material for rocket fuel.

Water ice has also been identified on several asteroids. Musk has proposed capturing asteroids for harvesting raw materials. H2O is a raw material.

A good proof-of-concept would be to build a solar-powered rocket fuel plant here in earth where it’s cheap, easy and safe, before staking the lives of hundreds of colonists on the technology.
