Here’s a good rundown of earth history. I’ve been finding myself reading into earlier geologic time periods out of sheer fascination.
The Martian atmosphere presents a slew of problems to engineers trying to safely land heavy cargo on the planet’s surface. Its atmosphere is much less dense than that of Earth’s, so parachutes that would slow a spacecraft’s descent would need to be prohibitively large.
That’s why aerospace researchers are investigating the best ways to fire a descending vehicle’s engines to slow it down, a technique called retropropulsion. Figuring it out would let cargo ships touchdown without destroying the tons of equipment and habitats that human astronauts need to create a base on Mars.

I hope you like her! :-)

So figured I would post this here and promote my Weasyl since FA is down.
