Mars Base Camp its moons (Deimos and Phobos), and serve as a proving ground in preparing humans for future missions to the Martian surface. The concept was published in May 2016 by Lockheed Martin, and it is a design for a spacecraft for carrying humans to Mars orbit and conducting operations in Mars orbit. Mars Base Camp harnesses many NASA technologies in development, or technology goals at the time of the 2010s. In September 2017, the plan was updated including a concept for a reusable crewed shuttle called MADV (Mars Ascent Descent Vehicle), which would connect to the MBC Mars space station. Mars
Moons of Mars infrared suggest a composition containing mainly phyllosilicates, which are well known from the surface of Mars. The spectra are distinct from those of all classes of chondrite meteorites, again pointing away from an asteroidal origin. Both sets of findings support an origin of Phobos from material ejected by an impact on Mars that reaccreted in Martian orbit, similar to the prevailing theory for the origin of Earth's moon. The moons of Mars may have started with a huge collision with a protoplanet one third the mass of Mars that formed a ring around Mars. The inner part of the ring
