NASA and Spacex is planning to develop A human colony on Mars

SpaceX is quietly planning Mars-landing missions with the help of NASA and other spaceflight experts. It's about time.

• SpaceX, founded by Elon Musk, is building a rocket-and-spaceship system to land people on Mars.
• Musk said he wants to launch the first humans to Mars in 2024, following an uncrewed mission in 2022.
• As Ars Technica reported, SpaceX held a private "Mars Workshop" with NASA and other experts to draft plans for its Mars landings.
• Experts say setting up a viable outpost, let alone a colony, on Mars is more daunting than Musk has let on.
