Following two intense and groundbreaking test flights in 2023, SpaceX’s Starship is poised for action once more at the Starbase launch site in Boca Chica, Texas. This deep-space rocket system is on the cusp of undergoing an hour-long integrated flight test. A successful mission will see the spacecraft descend into the Indian Ocean, marking a significant step towards more intricate test flights and the eventual goal of transporting NASA astronauts to the lunar surface.
The upcoming launch is scheduled within a 110-minute window, starting at 7 a.m. CT (8 a.m. ET) on Thursday. SpaceX plans to stream the event live on its website, starting approximately 30 minutes before the eagerly awaited liftoff. On Thursday morning, slight adjustments were made to the launch timing.
SpaceX announced, “The Starship team is go for prop load but keeping an eye on winds, now targeting 8:25 a.m. CT for liftoff,” via the social media platform X. Efforts are underway to ensure the Gulf of Mexico’s “keep out area” is clear of boats, according to SpaceX.
The Starship system is pivotal to SpaceX’s foundational goal of pioneering human missions to Mars. Notably, NASA has selected Starship as the designated lander for the Artemis III mission, which aims to transport astronauts to the moon, potentially as early as September 2026.
Should Thursday’s test proceed as planned, the Super Heavy booster—the launch vehicle’s first stage—will ignite and ascend over the Gulf of Mexico. Approximately three minutes into the flight, after consuming most of its fuel, the Super Heavy booster will detach from the Starship spacecraft. The booster is designed to execute an autonomous, controlled ocean landing, while the Starship continues its journey at high speeds.
SpaceX CEO Elon Musk has emphasized that reaching orbital speeds is a primary objective of these initial test flights. Achieving a stable Earth orbit typically requires velocities exceeding 17,500 miles per hour (28,000 kilometers per hour). However, this test flight will not attempt orbital entry but will instead aim for a controlled landing in the Indian Ocean, far from any landmass, as outlined by the Federal Aviation Administration.
The mission will also feature several critical tests and technological demonstrations. These include opening the payload door and a “propellant transfer demonstration,” essential for future satellite deployment missions and in-orbit refueling processes, respectively.
Refueling in orbit is crucial for the high-profile missions Starship will undertake, especially for the Artemis moon mission. This will involve the spacecraft remaining in Earth’s orbit while separate launches deliver the necessary fuel for lunar transit, potentially requiring over a dozen refueling operations.
Regulatory approval for this latest test flight was granted on Wednesday. Approximately 40 minutes into the flight, Starship will attempt to reignite its engines before descending towards the ocean.
Musk has expressed increased confidence in the success of this flight compared to previous attempts in 2023, citing an 80% probability of reaching orbit. Despite this optimism, SpaceX acknowledges the exploratory nature of these flights, emphasizing their role in the company’s rapid, iterative development strategy to foster major innovations.
This approach underscores SpaceX’s commitment to advancing space exploration and achieving its ambitious goals, including the historic mission of carrying humans to Mars.
