How NASA put MEN on the Moon in 1969

Mars would maybe be doable. Much farther than that and it would be a multi-generational trip. People wouldn't teach their kids much more than what they needed to know in order to navigate the ship. After a while it would be Lord of the Flies in there. Competing factions, and outcasts, etc. They'd have no first hand knowledge of where they came from, and no reason to even care.

Humans have been aboard the ISS in the time it would take to get to Mars. But the ISS is in low Earth orbit and enjoys magnetic shielding as a result. Exposure to radiation bursts from the Sun would be a problem for any Mars trip. I think if humans go to Mars it will be to stay, one way trip.

The asteroid concept is arguably more "commercial".

The Kardashev Scale is a classification scheme that ranks three levels of civilization based on their ability to harness energy.

Type I - Has the energy of the entire planet. Power to control the weather - earthquakes, volcanoes, etc. They can be modified.

Type II - Master the energy of a star. The ability to colonize nearby planets. Star Trek would be a Type II civilization.

Type III - Galactic. The ability to harness the energy of black holes, roam the galactic space lanes, etc. Star Wars would be a Type III civilization.

On this cosmic scale we are a Type 0. We don't control the earth, the stars, or the galaxy. We get our energy from dead plants and animals.

It's estimated that the earth will have a Type I civilization in 100-200 years. This will help accelerate the upgrades to Type II and Type III civilizations.

If anything, it's interesting.

We could develop a massive energy course, say fusion, and still not be able to limit earthquakes and weather.

Doesn't Mars have radioactive dust, as well as global dust storms?

[cincydawg]

I don't believe Mars has notable radioactivity aside from what they received from the sun. It does have dust storms that are epic.

One of the main problems getting to Mars is periodic eruptions from the Sun of serious radiation. We could build rockets large enough to get stuff there and land humans safely. Getting them back would be a challenge unless they could generate hydrogen and oxygen whilst there sufficient to refuel.

The folks who don't think this was real are not credible anyway.

GOod stuff guys! I bet at the time this was so monumental!

It was incredible at the time. We were also mired in Vietnam and had some major riots and protests around the country.

But the economy was doing well and the budget was balanced.

The economy was doing well with domestic manufacturing and American consumption which created jobs.  Didn't have the mad imports of today.  Steel, shoes, clothing, home construction, etc were all booming well.

My own opinion is to use robots to explore as needed, not humans. If the aim is colonization, then it changes.

I like the asteroid idea for the latter better, at least as a first step.

Curiously, it takes more energy to get something to crash into the sun than to eject it from the solar system entirely.

Seems president Nixon had his doubts that they men would return from moon.

NASA plans a mission to put man on the lunar surface in 2024. I think it's called Artemis 3.
