SpaceX CEO Elon Musk took to Twitter Monday (Feb. 12) to share some new particulars on final week’s Falcon Heavy take a look at flight, together with why the large rocket’s core booster crashed. SpaceX can be constructing a brand new drone ship for rocket landings at sea, he added.

When SpaceX’s Falcon Heavy blasted off final Tuesday (Feb. 6) from NASA’s Kennedy House Middle Pad 39A in Florida, the rocket’s three first-stage boosters had been anticipated to return to Earth and land very similar to the corporate’s Falcon 9 rocket phases. The Falcon Heavy’s two facet boosters landed efficiently (and concurrently) on twin pads on the close by Cape Canaveral Air Pressure Station, however the middle core crashed and burned. 

That core booster, which was anticipated to land offshore on SpaceX’s drone ship “Of Course I Nonetheless Love You,” crashed when two of three engines didn’t fireplace throughout a closing touchdown burn, Musk advised reporters after the launch. The booster missed the touchdown ship by about 328 ft (100 meters) and hit the water at 300 mph (484 km/h), damaging thrusters on the close by droneship, Musk has stated.

On Monday, we realized a bit extra in Musk’s Twitter posts. The 2 engines didn’t fireplace as a result of they ran out of ignition fluid, Musk stated.

“Not sufficient ignition fluid to mild the outer two engines after a number of three engine relights,” Musk wrote. “Repair is fairly apparent.”

That means a repair would possibly contain merely including extra ignition fluid, although Musk didn’t elaborate. 

Musk did share one tantalizing tidbit about future Falcon Heavy booster landings: SpaceX is constructing a 3rd drone ship for offshore rocket landings.

Its title? “A Shortfall of Gravitas.” 

The ship seems to be named in honor of the fictional spaceship “Experiencing A Vital Gravitas Shortfall” within the science fiction books “Look to Windward” and “Matter” by the late writer Iain M. Banks. SpaceX’s different two drone ships —”Of Course I Nonetheless Love You” and “Simply Learn The Directions” — are additionally named for ships talked about in Banks’ Tradition novels.

“A Shortfall of Gravitas” is beneath building now and can be part of “Of Course I Nonetheless Love You” in Florida to assist offshore landings of Falcon Heavy facet boosters, Musk wrote. “Simply Learn The Directions” is used for Falcon 9 landings after launches from SpaceX’s pad at California’s Vandenberg Air Pressure Base. 

SpaceX has additionally constructed one other ship with large steel arms to catch the protecting payload fairings (or nostril cone halves) on its rockets earlier than they fall into the ocean. You possibly can see an image of it right here. Musk has stated up to now that SpaceX’s fairings price about $5 million, so catching them for reuse might be a big financial savings. 

“It is like an enormous catcher’s mitt, in boat type,” Musk advised reporters after the Falcon Heavy launch. SpaceX might attempt to seize a falling Falcon rocket fairing someday this 12 months, he added.

Within the meantime, SpaceX nonetheless has a full slate of Falcon 9 and Falcon Heavy launches on faucet in 2018. The corporate’s subsequent launch is scheduled for Saturday (Feb. 17) from Vandenberg Air Pressure Base. It would use a Falcon 9 rocket to launch the Paz Earth monitoring satellite tv for pc into orbit for Spain.

At the very least two extra Falcon Heavy missions are on the docket for this 12 months, together with the various Falcon 9 missions for satellite tv for pc clients and NASA, which makes use of SpaceX’s Dragon cargo ships to ship provides to the Worldwide House Station. 

SpaceX can be constructing a crewed model of Dragon to fly astronauts for NASA. The primary take a look at flight of that ship on a Falcon 9 rocket can be anticipated in 2018.
