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.
