BOCA CHICA, Texas, April 17 (Reuters) – Elon Musk's SpaceX known as off the extremely anticipated debut launch of its newly mixed Starship cruise vessel and Tremendous Heavy rocket within the closing minutes of countdown on account of a frozen valve, delaying the uncrewed check flight for no less than two days.
The 2-stage rocketship, standing taller than the Statue of Liberty at 394 toes (120 m) excessive, was initially slated for blast-off from the SpaceX “Starbase” facility at Boca Chica, Texas, throughout a two-hour launch window that started at 8 a.m. EDT (1200 GMT).
However the California-based firm introduced in a reside webcast that it was scrubbing the deliberate 90-minute flight into area for at least 48 hours, citing a frozen pressurization valve within the lower-stage rocket booster. That may make Wednesday the following out there launch window for the mission.
SpaceX later mentioned on Twitter that its groups had been “working in direction of Thursday, April 20” for a second launch try.
The tweet set off a flurry of jokes on the social media platform making reference to 4/20 as a date broadly related to hashish tradition, and to the notoriety Musk gained in 2018 for smoking marijuana throughout an look on a reside internet present.
Musk, who bought Twitter final yr for $44 billion, is the founder, CEO and chief engineer of SpaceX. He is also chief government of electrical carmaker Tesla, Inc.
Getting the Starship to area for the primary time would characterize a key milestone in SpaceX's ambition of sending people again to the moon and in the end to Mars – no less than initially as a part of NASA's newly inaugurated human spaceflight program, Artemis.
A profitable debut flight would additionally immediately rank the Starship system as essentially the most highly effective launch car on Earth.

Each the lower-stage Tremendous Heavy booster and the upper-stage Starship cruise vessel it could carry to area are designed as reusable elements, able to flying again to Earth for smooth landings – a maneuver that has develop into routine for SpaceX's smaller Falcon 9 rocket.
However neither stage could be recovered for the expendable first check flight to area. As a substitute, each elements of the spacecraft would finish their inaugural flight with crash landings at sea – the upper-stage of the Starship coming down within the Pacific after attaining almost one full orbit of the Earth.
Prototypes of the Starship cruise vessel have made 5 sub-space flights as much as 6 miles (10 km) above Earth in recent times, however the Tremendous Heavy booster has by no means left the bottom.
In February, SpaceX did a test-firing of the booster, igniting 31 of its 33 Raptor engines for roughly 10 seconds with the rocket bolted in place vertically atop a platform.
The Federal Aviation Administration simply final Friday granted a license for what could be the primary check flight of the totally stacked rocket system, clearing a closing regulatory hurdle for the long-awaited launch.
If all goes as deliberate for the following launch bid, all 33 Raptor engines will ignite concurrently to loft the Starship on a flight a lot of the means across the Earth earlier than it re-enters the ambiance and free-falls into the Pacific at supersonic velocity, about 60 miles (97 km) off the coast of the northern Hawaiian islands.
After separating from the Starship, the Tremendous Heavy booster is predicted to execute the beginnings of a managed return flight earlier than plunging into the Gulf of Mexico.
As designed, the Starship rocket is almost two instances extra highly effective than NASA's personal Area Launch System (SLS), which made its debut uncrewed flight to orbit in November, sending a NASA cruise vessel known as Orion on a 10-day voyage across the moon and again.
