NASA Planetary Science Division Director Jim Green said on Tuesday that SpaceX plans to launch two Red Dragon missions to Mars during the 2020 launch window.
“Every 26 months, the highway to Mars opens up, and that highway is going to be packed. We start out at the top of that opportunity with a SpaceX launch of Red Dragon. That will be followed at the end of that opportunity with another Red Dragon. Those have been announced by SpaceX,” Green said during an appearance at the Humans to Mars Summit in Washington, DC.
The Red Dragon is a modified version of the Dragon spacecraft SpaceX uses to deliver supplies to the International Space Station. SpaceX will send these automated vehicles to the surface as a precursor to human missions it wants to fly in the 2020’s.
SpaceX has announced that it will send a Red Dragon to the surface in 2020. However, Elon Musk’s company has said nothing publicly about a second spacecraft. Red Dragons are designed to perform automated descent, entry and landings on the martian surface.
SpaceX had planned to launch the first Red Dragon mission in 2018. However, the effort was pushed back two years due to the company’s other commitments, which include commercial cargo and crew missions for NASA and a backed up launch manifest caused, in part, by two Falcon 9 failures.
The inaugural flight test of the Falcon Heavy booster that will launch the Red Dragon spacecraft has also been delayed for more than four years. That test is currently scheduled for the third quarter of 2017.
NASA is providing about $30 million in in-kind support for the first Red Dragon flight in exchange for entry data. The space agency’s support includes trajectory analysis and tracking and communications via the Deep Space Network.
