It looks like we'll have to wait a little longer to see Starhopper make its biggest leap yet.
SpaceX had been hoping to launch Starhopper, an early test prototype of the company's Mars-colonizing Starship vehicle, to an altitude of about 650 feet (200 meters) this weekend from its facility in Boca Chica, Texas, near the border city of Brownsville.
SpaceX just needed to secure permission for the flight from the Federal Aviation Administration (FAA), company founder and CEO Elon Musk said via Twitter earlier this week.
Good conversation with head of FAA Space. Need a bit more hazard analysis & should be clear to fly soon.August 15, 2019
On Thursday (Aug. 15), the billionaire entrepreneur tweeted another update: "Good conversation with head of FAA Space. Need a bit more hazard analysis & should be clear to fly soon."
But "soon" apparently means the middle of next week at the earliest. Officials in Cameron County, where Boca Chica lies, announced Friday (Aug. 16) that Boca Chica Beach and part of State Highway 4 will be closed on Aug. 21 from 2 p.m. to midnight local time to accommodate SpaceX activities.
Aug. 21 is the "primary date" for the closure, and Aug. 22 and Aug. 23 are alternates, Cameron County officials added.
Starhopper has flown three times to date, all of them from Boca Chica. The stubby vehicle made two brief tethered hops in early April and flew freely for the first time on July 25, on a test flight that had a targeted altitude of 65 feet (20 m).
Starhopper has one Raptor engine. The final, 100-passenger Starship vehicle will have six Raptors, Musk has said, and Super Heavy — the giant rocket that will launch Starship off Earth — will have 35. These numbers could change, however; Musk is scheduled to give us a Starship design update next week.
If all goes according to plan, the reusable Starship-Super Heavy duo could begin launching satellites as early as 2021, SpaceX representatives have said.
The spaceflight system has one official mission on its docket — a trip around the moon booked by Japanese billionaire Yusaku Maezawa, who plans to fly with a small group of artists. That mission is currently targeted for 2023.
