Taking off from SpaceX's Starbase facility in Boca Chica, Texas, the launch occurred at 7:00 am local time (1300 GMT). This test was crucial for Starship, especially following a previous attempt in April that ended in an explosion. This latest test, despite encountering an issue later in the flight, marked a substantial achievement for SpaceX.
Throughout its development, SpaceX has maintained that learning from explosive tests is a vital part of evolving their space technology. This philosophy is evident in their commitment to innovation and in their pursuit of making space travel more affordable through fully reusable spacecraft.
During this second test, the full stack, consisting of Starship and its reusable rocket booster, showcased several significant advancements. The rocket, standing 397 feet (121 meters) tall, employed the innovative "hot staging" separation technique, drawing inspiration from Russian rocket designs to potentially unlock greater power. Notably, the reusable rocket booster successfully separated and tumbled away, remaining intact for about 30 seconds before exploding.
However, the test encountered a complication approximately eight minutes into the flight. Traveling over 24,000 kph at an altitude of 148 km, Starship experienced an issue at what was expected to be the second-stage engine cutoff (SECO) event, leading to a loss of signal and most likely loss of the vehicle. The details of this anomaly are currently unclear and will be the subject of a detailed investigation by SpaceX and regulatory authorities including the FAA.
Despite this issue around the time of SECO, the test represents a major step forward from the first launch, which saw multiple failure through to spacecraft being destroyed by onboard safety systems. The successful execution of the initial phases, including lift-off and hot stage separation, underscores significant progress in Starship's development.
Starship is not just a rocket but a fully reusable spacecraft designed for future interplanetary missions, including Elon Musk's vision of Mars colonization. It's also slated to play a key role in NASA's Artemis program, which aims to land humans on the Moon by 2025. The rocket's Super Heavy booster, capable of producing 16.7 million pounds of thrust, highlights its potential in transforming human space exploration.
Ahead of this test, SpaceX implemented several upgrades to both the Starship and its launch infrastructure. These included venting system improvements to minimize explosion risks and the reinforcement of the Starbase launchpad to withstand the immense heat and force of the launch.
[An earlier version of this report said range control manually destroyed the rocket, is has now been established that the destruct sequence was auto initiated when it was determined the rocket was not capable of reaching the mid Pacific.]
