Elon Musk Says SpaceX’s About to Launch And ‘Hover’ a Mars Rocket Prototype

SpaceX is about to carry out its most bold test-launch but of a shiny Mars rocket prototype in south Texas.

Employees have descended upon the growing coastal launch website over the previous eight months to construct and put together the stout, three-legged prototype for testing. It is constructed out of stainless-steel, has the form of a badminton shuttlecock, and is provided with considered one of SpaceX’s next-generation Raptor rocket engines.


Elon Musk, the rocket firm’s founder, named the roughly six-story-tall rocket ship “Starhopper” as a result of it is not constructed to fly into house however somewhat to “hop” to altitudes no larger than about three miles (four.eight km).

Starhopper is a prototype for a way more highly effective and roughly 400-foot-tall (122-meter-tall) launch system often known as Starship: a car that Musk and his firm envisions taking dozens of individuals to the Moon or Mars, deploying lots of of satellites at a time, or rocketing individuals round Earth in a matter of minutes.

SpaceX fired up Starhopper for the primary time on April. That check secured the rocket ship with big, bike-chain-like tethers on its legs, and the car lifted the ship no various inches off the bottom. Subsequent assessments lifted it up farther, however not by a lot.

Subsequent week’s check will launch it fully untethered.

“Raptor engine mounted on Starhopper. Aiming for hover check Tues,” Musk tweeted on Friday.

Engineers hope to take the car as much as about 65 ft (20 meters) – about one full Starhopper peak. Musk additionally says Starhopper will transfer sideways, after which attempt to land again on its launchpad.


A SpaceX spokesperson informed Enterprise Insider in an e-mail that the hop-and-hover check is “one in a sequence of assessments designed to push the bounds of the car as shortly as doable to be taught all we will, as quick as we safely can.”

When a Twitter consumer requested Musk if there could be live-streaming video of the launch try, Musk stated “Positive.”

Highway closure notices issued by Cameron County, Texas, recommend SpaceX will attempt to launch Starhopper between 14.00-20.00 CT (15.00-21.00 ET) on Tuesday, July 16.

A launch at that second is something however assured, although.

“As with all growth applications, the schedule may be fairly dynamic and topic to vary,” the spokesperson stated.

What to anticipate with SpaceX’s first ‘hover’ check for Starhopper

Earlier than making an attempt a full hop-and-hover launch, SpaceX must put the Starhopper and its new engine via a sequence of assessments.

The corporate will doubtless movement liquid oxygen via the brand new Raptor engine over the weekend to verify its plumbing and . If this preliminary check succeeds, the corporate might try what’s referred to as a static hearth check on Monday.


The static hearth check would add methane to the flowing oxygen, ignite each fuels, and burn the Raptor engine for a matter of seconds to point out it is functioning usually. (Methane makes up most pure fuel on Earth, and it is a gasoline Musk hopes to fabricate on Mars with a deliberate house colony.)

The static hearth check might resemble SpaceX’s temporary launch of Starhopper on April 6, which briefly lifted it off the bottom:

If there are any delays main as much as these and different essential pre-launch assessments, SpaceX will nearly definitely delay its deliberate Starhopper hover. And if engineers uncover any issues through the assessments, SpaceX might scrub its present plans, make obligatory fixes, and check out once more at a later date.

Musk had hoped to drag off Starhopper’s hop-and-hover launch try a number of weeks in the past, however he stated a earlier Raptor engine had a mechanical failure and vibration points. The latest Raptor engine, referred to as “serial quantity 6” or SN6, has apparently resolved these snags.

“Hopper nearly able to hover,” Musk tweeted on July 7, displaying a photograph of a brand new Raptor engine test-fire on the firm’s rocket-testing plant in central Texas.

The village inside SpaceX’s Mars spaceport

SpaceX’s launch website for the Starhopper is positioned close to Boca Chica Seaside in south Texas. State and Cameron County politicians, in addition to the Federal Aviation Administration (FAA), gave the corporate remaining approval to develop the world in 2014.

Nonetheless, Boca Chica Village – a hamlet the place about 20 individuals stay – now finds itself in the midst of SpaceX’s increasing industrial website and future spaceport.


The easternmost fringe of the village is positioned about 1.5 miles from SpaceX’s beachside launch pad. Preliminary plans referred to as for launching Falcon 9 and Falcon Heavy rockets (about one a month), however Musk stated in early 2018 that SpaceX had deserted these plans.

Starhopper started to appear in late 2018, and Musk confirmed its existence with a sequence of pictures. The prototype initially had a nosecone, however highly effective Texas winds blew it off and broken it. That is why the car appears stubby and unfinished right now.

Starhopper is only the start of Starship’s growth program.

The corporate is now constructing a V-shaped wind block in its operations yard, say sources acquainted with the matter, the place it is also setting up a “Mark 1” (Mk1) Starship prototype. Musk says that car is designed to achieve orbit and – as a part of what he described as a pleasant competitors – staff are additionally constructing a near-identical Starship prototype close to Cape Canaveral, Florida, the place the corporate operates two different launch pads.

“Mk1 Starship hopefully 20 km [12.4 miles] up in just a few months,” Musk stated.

SpaceX’s present authorities licence, which the Federal Communications Fee granted in February 2019, solely permits the corporate to launch experimental automobiles to an altitude of three.1 miles (5 kilometers) for flights lasting as much as six minutes.

Musk tweeted in March that SpaceX is “engaged on regulatory approval” for orbital flights of Starship prototypes from each Texas and Florida.

The corporate plans to launch the prototypes into orbit round Earth earlier than the tip of 2020. Then, in 2023, Musk hopes to make use of a full-scale Starship to launch a Japanese billionaire and his hand-picked crew of artists on a voyage across the moon.

SpaceX president and COO Gwynne Shotwell reportedly stated that the corporate hopes to ship its first uncrewed payloads to Mars by 2024. Following that, maybe in 2026, SpaceX might attempt to put boots on the purple planet.

“It may very effectively be that the primary individual that departs for an additional planet may depart from this location,” Musk stated through the Boca Chica launch website’s groundbreaking in September 2014.
