Since the early 1970’s humans have not ventured past near earth orbit and it’s a great shame.
We should have landed on Mars ages ago, all we’ve done is stalled preferring to send robots.
Robots are incapable of human capacities and our inquisitive nature and, as has been shown in experiments on earth, can miss stuff like fossils openly on display on the surface. They are not great.
We need to go to Mars as soon as possible and we need to start colonising space and extraction raw materials from space because the earth’s resources are finite.
For this to happen we need more exotic faster cheaper propulsion systems, artificial gravity, inertial dampers, greater recycling abilities of air water and food for long journeys.
Who knows when the next extinction level event is coming?

American manned Mars expedition. Study 1969. Von Braun's final vision for a manned expedition to Mars was a robust plan that eliminated much of the risk of other scenarios. Two ships would fly in convoy from earth orbit to Mars and back.
Status: Study 1969. Thrust: 1,733.80 kN (389,774 lbf). Gross mass: 726,000 kg (1,600,000 lb). Unfuelled mass: 182,000 kg (401,000 lb). Specific impulse: 850 s. Height: 82.00 m (269.00 ft). Diameter: 10.06 m (33.00 ft).
They were entirely reusable for future expeditions, the only element being expendable being the Mars Excursion Module used to visit the planet's surface. This was Von Braun's last attempt to convince the American government to finance his dream. Five months later he would be sidelined to a dead-end headquarters job at NASA, and leave the Agency two years after that.

All these low earth orbit business for the last few decades have only served to hold us back in space exploration.

We're talking about continental drift, plate tectonics here?
And no, without looking it up. At a guess hundreds of thousands of years.

in a sense. is the ridge a remnant of the mid atlantic volcano at a time when only heavy water flowed on Earth?
