falcon 9

SpaceX'due south start resupply mission to the International Space Station since concluding yr'south explosive failure wasn't but a success — it marked the offset of a new era in human spaceflight. After several near misses, the Falcon ix rocket delivered its payload to orbit, then successfully landed on a drone transport, ready for refurbishment and reuse. This is the showtime time anyone has managed such a feat, and no one else is fifty-fifty close.

The launch on Fri afternoon went by the book from start to terminate with none of the delays we're used to seeing with important launches. The Dragon sheathing in the second stage of the rocket carried more than 7,000 pounds of supplies to the space station, including the Bigelow Expandable Activity Module, a test platform for expandable habitats in space that volition add 565 cubic feet of additional space to the ISS. It's mostly an experiment, so astronauts won't be spending a lot of time in the new module. The Dragon sheathing successfully linked up with the ISS over the weekend.

On whatever other day, this would have been the highlight of NASA'south commercial resupply program. However, SpaceX also took the opportunity to attempt another vertical landing with the Falcon 9 first stage. It previously managed to land the Falcon 9 on the ground following a launch late concluding year, but it blew upwards a few rockets attempting water landings before and since. Fri's attempt was the first time it worked.

Almost launch vehicles are single-utilize; the first stage falls off and drops into the ocean, meaning each future launch needs an entirely new rocket. A single Falcon 9 costs about $60 million, just the fuel for a launch is just $200,000. When you effigy in the cost of recovering, refurbishing, and refueling a rocket for reuse, SpaceX estimates it tin can reduce costs past most 30%. That would make the Falcon ix a much less expensive manner to reach infinite. It's hard to see how any other private space business firm can compete with that.

Equally for the drone ship, that's the key to SpaceX'southward plans. Landing on solid ground is easier, but only in one case y'all become there. A footing landing requires the rocket to turn around and propel itself back to land after releasing the second stage. That wastes a lot of fuel, but a drone ship can be positioned downrange (equally this one was in the Atlantic) to essentially "take hold of" the rocket. When a heavier payload is existence launched, the Falcon ix might non even have enough spare fuel to get back to land, so the drone send gives SpaceX the virtually flexibility in landing a rocket.

SpaceX opted not to reuse the rocket from its outset landing so it could be studied further. No plans for the newest recovered rocket have been announced yet. SpaceX does have a few satellite launches coming upwards in the next few months, and so it could be recovering fifty-fifty more rockets soon enough.
