In other news, Spacenews reports that SpaceX has been working with NASA to identify potential landing sites on Mars for both its Red Dragon spacecraft starting in 2020 and future human missions. SpaceX, working with scientists at NASA’s Jet Propulsion Laboratory and elsewhere, had identified several potential landing sites, including one that looks particularly promising — Arcadia Planitia. Those landing sites are of particular interest, he said, for SpaceX’s long-term vision of establishing a human settlement on Mars, but he said the company wouldn’t rule our sending Red Dragon spacecraft elsewhere on the planet to serve other customers. “We’re quite open to making use of this platform to take various payloads to other locations as well,” he said. “We’re really looking to turn this into a steady cadence, where we’re sending Dragons to Mars on basically every opportunity.” The Red Dragon spacecraft, he said, could carry about one ton of useful payload to Mars, with options for those payloads to remain in the capsule after landing or be deployed on the surface. “SpaceX is a transportation company,” he said. “We transport cargo to the space station, we deliver payloads to orbit, so we’re very happy to deliver payloads to Mars.” Fans of the book/movie "The Martian" would be happy if SpaceX does select Arcadia Planitia for their first landing site as that was the landing site of the Ares 3.
