Elon Musk’s SpaceX completed final preparations early Monday to launch its powerful new Starship rocket system into orbit for the first time, on a short but highly anticipated uncrewed test mission from the Texas Gulf Coast.
The SpaceX facility in Boca Chica, Texas was scheduled to launch the two-stage rocketship during a two-hour launch window that begins at 8 a.m. EDT (1200 GMT), making it higher than the Statue of Liberty at 394 feet (120 m).
Whether or whether its goals are fully achieved, the test voyage marks an important turning point in SpaceX’s plans to return people to the moon and eventually Mars. This is also the main purpose of a revitalised NASA spaceflight programme that is meant to include the Starship.
But even launching a spaceship, which, if it succeeds in taking off, would suddenly become the most powerful rocket on Earth, is very difficult for SpaceX.
The best-case scenario would reveal critical information on how the aircraft ascends to space and how it would fly back to Earth, Musk said to a private Twitter audience on Sunday night. “Success is not what should be expected,” Musk said.
He predicted that tomorrow probably won’t go well. “It’s just fundamentally very difficult,”
The California-based corporation earlier on Sunday said on Twitter that its launch teams were continuing to make preparations for the flight while closely monitoring any possible wind-shear conditions in the forecast that may cause a delay.
Musk said on Sunday night that a postponement of the flight rather than a Monday launch was “more likely.” SpaceX has backup launch opportunities at about the same hours on Tuesday and Wednesday.
Like A Meteor
Both the lower-stage Super Heavy booster rocket and the upper-stage Starship cruise ship that it will launch into orbit are intended to be reusable parts that may return to Earth for gentle landings, as has been standard practise for SpaceX’s smaller Falcon 9 rocket.
However, neither stage will be retrieved for the brief (less than 90 minutes), disposable first test voyage to space.
However, the Super Heavy rocket has never left the ground. In recent years, prototypes of the Starship cruise ship have performed five sub-space flights up to 6 miles (10 km) above Earth.
SpaceX tested the booster in February, firing it for around 10 seconds while strapped vertically atop a platform and firing 31 of its 33 Raptor engines.
A last legal barrier has been removed for the much anticipated launch after the Federal Aviation Administration only last Friday approved a licence for the fully stacked rocket system’s maiden test flight.
If everything goes according to plan on Monday, all 33 Raptor engines will fire at once to launch the Starship on a journey that almost completes a full orbit of the Earth before it re-enters the atmosphere and free-falls into the Pacific at supersonic speed, about 60 miles (97 km) off the northern Hawaiian islands.
The Super Heavy rocket will likely separate from the Starship and start a controlled return flight before crashing into the Gulf of Mexico.
The starship’s scorching re-entry over the Pacific will test its capacity to control itself aerodynamically using big flaps and for its heat shielding to endure the high friction created as it falls through the atmosphere.
Musk remarked, “The ship will be coming in like a meteor.” “This is the first leg of a long journey involving numerous flights.”
In Boca Chica, more Super Heavy boosters were already on deck for upcoming test flights, he said.
The NASA Space Launch System (SLS), which launched a NASA cruise ship dubbed Orion on its first unmanned mission to orbit in November, is roughly two times as powerful as the Starship rocket when used as intended. Orion conducted a 10-day trip around the moon and returned.
