Starship: Fill ‘er up!
SpaceX accomplished a profitable “flight-like” wet dress rehearsal of the Starship spacecraft’s fueling system this week (Monday, January 23, 2023). Starship is to be the world’s first absolutely reusable tremendous heavy-lift launch automobile. It stands 390 toes (120 meters) tall and has greater than twice the thrust of the mighty Saturn V rockets that carried astronauts to the moon 50 years in the past. Monday’s take a look at marked one of many last milestones on the trail to Starship’s first orbital take a look at flight. SpaceX is now saying an uncrewed first flight might occur as quickly as late February or March.
The testing happened on the firm’s Boca Chica, Texas facility. Afterwards, SpaceX shared a video on Twitter asserting the profitable loading and unloading of a staggering 10 million kilos (4.5 million kg) or so of liquid fuels into the stacked spacecraft:

The elements examined collectively Monday had been Booster 7 (B7) and the second-stage craft Starship 24 (SN24). When mated right into a behemoth rocketship – the world’s tallest, as SpaceX likes to say – the 2 craft are additionally referred to collectively (and a bit confusingly) because the Starship.
Burn, child! Burn!
One other crucial take a look at stays. Earlier than Starship can take to space, B7 can be anchored to the Earth whereas all 33 of its mighty Raptor engines are fired to verify it could possibly deal with the ability.
Collectively, SpaceX says a Starship booster’s engines create 17 million kilos (7,590 tons) of thrust. That’s roughly equal to 40.8 million horsepower or about “70 % of the worldwide horse inhabitants,” in accordance with customers at Reddit’s r/SpaceXLounge.
In anticipation of the take a look at, SpaceX has already unstacked SN24, shifting it to a secure location away from the testbed and the potential for injury at this late date. The corporate shared photos of SN24 yesterday (Wednesday, January 25, 2023) cradled by the mechanized arms – the chopsticks – hooked up to the Mechazilla launch and retrieval tower:

The corporate has but to announce a date for the total take a look at firing. Final month, B7 underwent a 14-engine static firing take a look at. NASASpaceflight.com shared video through YouTube:
Can I see your license, please?
As soon as a profitable last engine take a look at is full, a final hurdle stays: getting an experimental license from the Federal Aviation Administration (FAA).
SpaceX has already fulfilled the entire FAA’s requirements for the license, excluding the ultimate engine firing take a look at. In June, the FAA introduced SpaceX had agreed to steps to mitigate the environmental influence of its launches, signaling the allowing course of was largely full.
As soon as the FAA license is granted, Starship can fly.
SpaceX CEO Elon Musk – presently generally known as Mr. Tweet after he modified his title on the Twitter platform he owns and was prohibited from altering it again (what a man!) – mentioned the world’s largest rocket is able to fly:

Responding to a Twitter consumer’s estimated timeline, Musk agreed Starship might fly in February or March:
Does this sound about proper, Elon?
Cryotest as we speak, then WDR subsequent week. Destack for 33 engine Static Hearth. Last TPS work on Ship 24. Re-stack. Launch License.
Doable finish of Feb/Early March if all goes properly (per your earlier timeline)?
