NASA is about to land InSight: a new $830-million Mars lander that will probe the red planet’s secrets like never before.
InSight lifted off in May and is expected to land on Monday, but it’s just one of dozens of robotic and satellite missions that humanity has rocketed to Mars over the decades.
These spacecraft have beamed back dazzling photos, inspired sci-fi movies like “The Martian“, and even helped give Elon Musk, the founder of SpaceX, the idea to colonize the red planet with the Big Falcon Rocket.
While scientists readily admit they have much to learn about Mars, including the planet’s internal structure (a mystery InSight will try to solve), what we have found out so far is incredible.
Here are 13 fascinating facts about Mars and our robotic exploration of the red planet.
