Falcon 9 is now the only reusable rocket booster, which is a major selling point for SpaceX.
For the first time since launching the Falcon Heavy in February, SpaceX has failed to successfully land one of its reusable Falcon 9 rockets on land.
NASA spokeswoman Megan Powers wrote in an email that Musk met with NASA deputy director of exploration and human operations Bill Gerstenmaier in Washington.

Television cameras switched away from the rocket a moment before impact, but amateur video showed the rocket extending its landing legs and slowing for landing on the power of a single engine, the normal procedure for touchdown.

SpaceX has launched its unmanned Dragon cargo capsule, propelling its payload to the International Space Station (ISS) despite a post-launch failure affecting the first-stage rocket.

In April, he placed a moratorium on nuclear or long-range missile tests, saying his country no longer needed to conduct them. As of August 2018, researchers said North Korea is continuing to construct an extremely large underground facility.
The rocket carried more than 5,000 pounds of food and supplies to the ISS and launched from Cape Canaveral Air Force Station in Florida.
There was a problem with the grid fin hydraulic pump, he explained, so the rocket landed in the sea.
SpaceX commentator John Insprooker said, "We have done an excellent lift".
The rocket was initially meant to take off Tuesday but was delayed for a day after engineers discovered moldy mouse food in one of the science investigations created to study the effect of microgravity on the immune system.
It was the first time SpaceX ever failed to land a booster on solid ground, following a string of 12 straight successes.
The mission was SpaceX's 16th mission for NASA as part of a long-term contract to ferry supplies to space.
The rocket was being used to send a capsule of cargo up to the International Space Station.
