SpaceX Reveals Bold Plans for 5th Starship Test Flight on Sunday Morning
The plans come directly after the FAA issued the required licence after months of delays.
SpaceX has announced it is going ahead with its ambitious fifth Starship rocket test flight after being given the green light to go ahead by air safety regulators.
Founder, chief executive, and chief engineer Elon Musk has plans for SpaceX to be the first company to build a reusable spaceship and rocket, with the goal of ferrying people to the moon and Mars.
As the biggest and most powerful rocket ever built at 400 feet tall, intentions are for the Starship to be able to land on command upon returning to Earth. In the upcoming test, the aim is for the spaceship to make a precise controlled landing in the Indian Ocean.
The Starship-Super Heavy vehicle will launch from the company’s launch site in Boca Chica, south Texas.
In the previous test, the vehicle achieved its first full test mission around the globe without losing either the Starship craft or its Super Heavy rocket boosters. The Super Heavy stage reached its mission targets, plunging into the Gulf of Mexico waters shortly after takeoff after a successful separation from the Starship, which then engaged its own engines to blast further into space.
The Starship’s fourth flight lasted about 1 hour.
For its fifth test flight, SpaceX says it has an ambitious objective: to attempt to return the Super Heavy booster to the launch site in “another step towards full and rapid reusability.”
The company warned of “audible sonic booms in the area around the landing zone” caused by the returning booster, which will slow down from supersonic speeds and be caught in mid-air by the catch tower infrastructure that will be ready at the launch site, Starbase.
“Generally, the only impact to those in the surrounding area of a sonic boom is the brief thunder-like noise with variables like weather and distance from the return site determining the magnitude experienced by observers,” SpaceX said.
If any unacceptable conditions occur during the test, the Super Heavy booster will “default to a trajectory that takes it to a landing burn and soft splashdown in the Gulf of Mexico.”
This time, the Starship has also received key upgrades in the form of a complete rework of its heatshield.
“SpaceX technicians [spent] more than 12,000 hours replacing the entire thermal protection system with newer-generation tiles, a backup ablative layer, and additional protections between the flap structures,” the company said. “This massive effort, along with updates to the ship’s operations and software for reentry and landing burn, will look to improve upon the previous flight and bring Starship to a soft splashdown at the target area in the Indian Ocean.”
FAA Delays
Despite earlier delays, the FAA’s Saturday approval came sooner than expected. The regulator had previously told SpaceX that its launch license wouldn’t be granted until late November due to changes to Starship’s flight profile that needed a “more in-depth review” involving other agencies would need to be consulted about the flight’s environmental impact.
“This will be a singularly novel operation in the history of rocketry,” the company said of the plans for the fifth test in September. “SpaceX goes to the maximum extent possible on every flight to ensure that while we are accepting risk to our own hardware, we accept no compromises when it comes to ensuring public safety.”
Musk says he plans for the Starship to eventually replace the company’s workhorse; the reusable, two-stage Falcon 9 rocket. SpaceX’s launch business already lofts most of the world’s satellites and other commercial payloads into space.
