SpaceX's 1st orbital Starship looks supercool in these fueling test photos

SpaceX performed a Starship wet dress rehearsal on Jan. 23, 2023, fueling the giant vehicle up for the first time ever. As this photo shows, the stainless-steel Starship went frosty white after the loading of supercold propellant.

SpaceX fueled up a fully stacked Starship vehicle for the first time ever on Monday (Jan. 23), and dramatic photos preserve the process for posterity.

The 395-foot-tall (120 meters) Starship is an icy white in the new photos, which SpaceX released via Twitter on Tuesday (Jan. 24). 

That's a dramatic color shift for the silvery Starship, brought on by the loading of more than 10 million pounds (4.5 million kilograms) of supercold liquid oxygen and liquid methane propellant into the stainless-steel vehicle's tanks.

The fueling was part of a landmark "wet dress rehearsal" that SpaceX performed on Monday at its Starbase facility in South Texas. 

During wet dress rehearsals, mission teams practice many of the procedures they will perform on launch day. Monday's test will help SpaceX prepare for a very important Starship liftoff — the vehicle's first-ever orbital test flight, which company founder and CEO Elon Musk has said could take place as early as next month.

But this Starship vehicle, which consists of a first-stage prototype called Booster 7 and an upper-stage spacecraft known as Ship 24, must pass a few more tests before embarking on that milestone flight, as SpaceX explained.

"After completing Starship's first full flight-like wet dress rehearsal, Ship 24 will be destacked from Booster 7 in preparation for a static fire of the Booster's 33 Raptor engines," the company said in another Tuesday tweet

Static fires are another common prelaunch test, in which engines are briefly ignited while a vehicle remains anchored to the ground. To date, Booster 7 has static-fired a maximum of 14 of its 33 Raptors simultaneously. Ship 24 lit up all six of its Raptors last September.

SpaceX has big plans for Starship. Musk believes, for example, that the giant vehicle could soon make Mars settlement economically feasible. And he has said that Starship will eventually handle most, if not all, of SpaceX's spaceflight duties.

NASA is invested in Starship as well. For instance, the agency selected the vehicle to be the first crewed lander for its Artemis program, which aims to establish a permanent, sustainable presence on and around the moon by the end of the 2020s. A Starship will land astronauts near the moon's south pole for the first time in 2025 or thereabouts, if all goes according to plan.

Editor's note: This story was corrected at 1:30 p.m. ET on Jan. 26 to state that 10 million pounds is equivalent to about 4.5 million kilograms, not 450,000 kilograms.
