SpaceX is ready to launch a brand new prototype of its Starship megarocket on a key take a look at flight Thursday — one that would take astronauts again to the moon.

The take a look at would be the twelfth outing for Starship however the first launch of the brand new third-generation Starship, dubbed V3, which is larger, extra highly effective and a step nearer to being absolutely reusable.
The rocket is scheduled to elevate off from a brand new launchpad at SpaceX’s Starbase facility on the southern tip of Texas throughout a launch window that opens at 6:30 p.m. ET.
Thursday’s flight might be intently watched as a result of NASA hopes to make use of Starship to land its astronauts on the lunar floor. As a part of NASA’s Artemis program, SpaceX and Jeff Bezos’ Blue Origin are constructing lunar landers that NASA may use for a deliberate moon touchdown in 2028. It goals to check one or each new automobiles in low-Earth orbit on the Artemis III mission late subsequent yr.
Starship’s final take a look at flight was seven months in the past. Since then, the rocket’s booster, often known as Tremendous Heavy, and its higher stage, referred to as Ship, have undergone in depth redesigns.
Starship V3 measures 408 toes tall absolutely stacked, a number of toes taller than its predecessor. SpaceX additionally added new Raptor 3 engines on Tremendous Heavy and Ship. Collectively, they’ll be capable of generate round 18 million kilos of thrust.
Different upgrades included decreasing the variety of “grid finds” on the booster, that are options on the high that assist to information the rocket’s first stage again to Earth, and growing the amount of Starship’s propellant tank.
“Collectively, these new parts are designed to allow a step-change in Starship capabilities and purpose to unlock the car’s core capabilities, together with full and fast reuse, in-space propellant switch, deployment of Starlink satellites and orbital information facilities, and the power to ship folks and cargo to the Moon and Mars,” SpaceX mentioned on its web site.
Throughout Thursday’s suborbital take a look at flight, Starship will attempt to deploy 22 mock Starlink satellites. SpaceX may also attempt to relight one of many higher stage’s six Raptor engines in area, an vital functionality for deorbit burns when the car ultimately returns to Earth.
The take a look at flight is anticipated to final about 65 minutes. Just like earlier outings, the higher stage ought to splash down within the Indian Ocean on the finish of the mission. SpaceX ultimately plans to make Ship reusable and “catch” the spacecraft with mechanical arms on the launch tower at its South Texas facility.
SpaceX has demonstrated comparable catch maneuvers with Starship’s Tremendous Heavy booster on earlier take a look at flights. This time round, the booster is ready to land offshore within the Gulf of Mexico and can not attempt to return to the Texas launch website for a catch, in keeping with SpaceX.
SpaceX faces a decent timeline with its improvement of Starship. The rocket, which made its debut flight in 2023, suffered a string of failures final yr, together with an uncontrolled re-entry by Earth’s environment and two midflight explosions because the upper-stage automobiles have been accelerating into area. SpaceX hopes to have Starship prepared for subsequent yr’s Artemis III mission, which requires the rocket’s higher stage to rendezvous with NASA’s Orion capsule — the car that carried the Artemis II astronauts across the moon final month — in orbit.
If all goes nicely, SpaceX will then work to get Starship licensed to hold NASA astronauts to the moon in 2028.
