More quickly than anyone expected, NASA embraces reuse for human flights:

Weather permitting, SpaceX's Crew Dragon spacecraft will splash down in the Gulf of Mexico on Sunday. Forecasters are closely watching conditions due to Hurricane Isaias but are hopeful the mission will find calm seas and light winds offshore from the Florida Panhandle.

[...] Although the company's next human spaceflight, Crew-1, will launch no earlier than late September on a new Falcon 9 rocket and Crew Dragon spacecraft, that will not be the case for the subsequent mission. This Crew-2 flight, due to launch no earlier than spring 2021, will reuse the Falcon 9 first stage from the Crew-1 mission, and the Dragon capsule is expected to splash down this weekend.

[...] The reuse of rockets and spacecraft always seemed like it would be part of SpaceX and NASA's extended plans for human spaceflights, but few anticipated it happening so quickly. NASA's original commercial crew contract with SpaceX called for the first six operational missions to each use new Dragons.

However, a contract modification signed in May allowed SpaceX to introduce reuse much more quickly. In exchange for extending the Demo-2 test flight—carrying NASA astronauts Doug Hurley and Bob Behnken—from two weeks to up to 119 days, SpaceX got permission to reuse spacecraft instead of building new ones. This extension allowed Behnken to participate in four spacewalks in recent weeks, swapping out battery packs on the exterior of the orbiting laboratory.

The move toward reuse was supported by NASA Administrator Jim Bridenstine. "From my perspective, what we're really looking for in all of our missions is sustainability," he said.

    Might reused rockets be more reliable than new ones, because they are known to have been assembled properly?

    That is one of the arguments SpaceX uses and why they like the term "flight-proven".

      it's not just that it's re-usable, methinks but that you can walk up to the device after use and actually SEE where use has been at work?
      sure, you can build a one-way rocket that works but you will never be able to be sure that it actually performed as intended because, maybe, just maybe if it fired 3 seconds longer it might have exploded?
      so if you can use a device and inspect it after use you can actually IMPROVE on the design: "ohhh-weehhh, look this screw nearly broke!" -or "ohhh-weeh, look, this seal was at its limit!" ... maybe? yes? no?
