NASA astronauts will soon start flying on used SpaceX vehicles, if all goes according to plan.
The agency has approved the use of preflown Crew Dragon capsules and Falcon 9 rockets on SpaceX's crewed missions to the International Space Station (ISS), SpaceNews reported Tuesday (June 16).
The green light comes via a recent modification of the $2.6 billion Commercial Crew Transportation Capability (CCtCap) contract that SpaceX signed with NASA in 2014, SpaceNews' Jeff Foust wrote. CCtCap funding covered final development work on Crew Dragon and the two-stage Falcon 9 for human spaceflight and also pays for at least six operational crewed missions to and from the ISS using the duo.

"In this case, SpaceX has proposed to reuse future Falcon 9 and/or Crew Dragon systems or components for NASA missions to the International Space Station because they believe it will be beneficial from a safety and/or cost standpoint," NASA spokesperson Stephanie Schierholz told SpaceNews. "NASA performed an in-depth review and determined that the terms of the overall contract modification were in the best interests of the government."
The first flight with used hardware could be Crew-2, the second contracted mission, which will likely lift off sometime in 2021, SpaceNews reported. Crew-1, which could launch as early as Aug. 30 of this year, will use a new Crew Dragon and Falcon 9, as the Demo-2 test flight did.
Demo-2 launched on May 30, sending NASA astronauts Bob Behnken and Doug Hurley to the ISS on SpaceX's first-ever human spaceflight and the first orbital crewed mission to lift off from U.S. soil since NASA retired its space shuttle fleet in 2011.
It's unclear at the moment when Behnken and Hurley are coming back down to Earth. NASA has not yet announced an end date for Demo-2, which could last as long as four months.
Boeing also holds a CCtCap deal with NASA, a $4.2 billion contract the aerospace giant aims to fulfill using a capsule called CST-100 Starliner. Boeing's contract, which was also signed in 2014, allowed Starliner reuse from the start.
Reuse is key to the vision of SpaceX and its billionaire founder and CEO, Elon Musk. Musk has long said that rapid and complete reuse of space hardware is the key breakthrough needed to slash the cost of spaceflight, which in turn will enable Mars colonization and other ambitious exploration feats.
SpaceX already routinely lands and re-flies the first stages of its Falcon 9 and Falcon Heavy rockets, and the company has been launching used Dragon cargo capsules to the ISS since 2017. (SpaceX holds a separate NASA contract to make robotic resupply runs to the orbiting lab.)
SpaceX also has been making progress recently in recovering and reusing payload fairings. These clamshell-like coverings, which protect satellites during launch, are worth about $6 million apiece, Musk has said. (Dragon capsules, both cargo and crew, launch without fairings.) Falcon 9 and Falcon Heavy upper stages remain expendable at the moment.
