SpaceX has successfully flown and landed a used booster for its CRS-13 resupply mission for the International Space Station (ISS):

SpaceX's first flight with a pre-flown booster for NASA was a success. After launch, SpaceX successfully touched down its used Falcon 9 rocket at the company's ground-based Landing Zone 1 at Cape Canaveral. This marks the 14th landing SpaceX has pulled off this year, and the second time this particular vehicle has landed following take off. This is also their 17th launch of 2017.

[...] This morning's launch will carry nearly 4,800 pounds of cargo to the ISS. Included on board is a sensor designed to monitor how much space debris is surrounding the station, as well as another sensor that's supposed to measure how much sunlight reaches the Earth.

It's a triple-play!

    Used booster launching a Used Dragon from an Old pad and sticking the landing for the umpteenth time in a row ... We demand New stuff !

      They still have to land an entire fairing for reuse.

      Then there's Falcon Heavy, launch likely in January.

        The Fine Summary kind of missed the fact that this was a used Dragon.
        That's pretty significant.

    I finally watched a video of spacex booster launch and landing. Damn, the thing take off vertically, and then land back on the pad vertically. It's a sci-fi shit from the 70s.

      Although they landed it on the ground this time, landing on an autonomous drone ship is always interesting.

      Watching these hover slam landings [stackexchange.com] just never gets old.
      They should build a pad right next door to the booster refurb plant and save all that transporting back and forth.

      This is a reflight of the dragon capsule as well, and they are working on landing the second stage as well.

        The final (they say) version of Falcon 9 will have better thrust, reusability and need less refurbishment:

        https://en.wikipedia.org/wiki/Falcon_9_Block_5 [wikipedia.org]

        Elsewhere it is stated that they want to reuse a booster within a day or so:

        That might be rare unless the pace of launches is much higher than it is now.

          need less refurbishment:

          In the video they mentioned they are doing less refurb, and launched this one without even washing off the soot from the last launch.
          The did paint some parts near the bottom end, because the paint there is functional ablative paint that keeps the underlying metal cooler.

            I would point to the stuff listed in the Block 5 Wikipedia article.

            7-8% increased thrust. Rather than carrying more payload with this, you could reserve a little more fuel to land the first stage (and second?). More customers would be able to choose the reusable launch profile (instead of expendable) due to the thrust increase.

            Titanium grid fins which were tested on one of the current rockets, but I don't know if they are standard yet. Needs no refurb between launches.

            Thermal protection coating. Only on the first stage it seems. A reminder that recovering the second stage will be quite difficult, or rarely attempted if it lowers the payload of the rocket too much.

            Retractable landing legs which make it quicker and more convenient to move the thing.

            Reusable heat shield protecting the engines and plumbing at the base of the rocket. I'd like to learn more about this one.

            Although there is routine landing/reuse of Falcon 9 in 2017, these improvements could be exactly what are needed to make reuse economical. After a few launches of Block 5, we might see lower prices on the SpaceX website.

              > Reusable heat shield protecting the engines and plumbing at the base of the rocket. I'd like to learn more about this one.

              Given that the last two landings I watched (not this one) had fire at the bottom of the rocket right after touchdown, and considering they fall back through most of the atmosphere at supersonic speeds despite looking like a glorified brick, I'd really like to know more about the stresses that the shield is designed against. Anyone got any specs, or is that top secret ?

    Space travel is a hoax. Everything NASA says is a lie. They lie about everything.

    ISS does exist, but here on earth. Space walks are filmed inside water tanks then using simple technology made to look like it all happened in space.
