Mars
3 items · 1 videos · updates automatically
Mars is a rocky planet, the fourth from the Sun. It’s known as the Red Planet because of the iron oxide on its surface. The planet has a thin atmosphere, seasons and polar ice caps, and is much smaller, colder and drier than Earth.
Evidence suggests that water was present on Mars in the past, and the planet may once have had conditions suitable for microbial life. But no conclusive evidence of life has been found, and there is no proof that life exists there today. A documentary explores ancient-alien theories about Mars, but does not present them as fact.
Here you’ll find articles about testing remote control of a Mars rover and a proposal for fuel that could reach the planet. The site also features a review of a documentary about ancient-alien theories, NASA and deep-space exploration.
