The SN8’s engine shut off during its descent, causing it to freefall rapidly.
SpaceX’s Starship prototype rocket achieved a record-breaking launch height on its test flight on December 9 in the South Texas village of Boca Chica. The SN8 (being the eighth Starship prototype) managed to reach 12.5 kilometers in 6 minutes and 42 seconds before crashing during its landing attempt. This was significantly higher than its fifth and sixth tests back in August and September, respectively. Video footage via tracking camera on the landing pad showed how the rocket hurtled during its descent before belly flopping in the sky and exploding on impact.
The SN8 launched around 4:40 p.m. U.S. Central Time from SpaceX’s Texas test facility. In the video, it can be seen how the SN8 began shutting off its three Raptor engines in succession during descent before tipping its nose cone to flip into position for landing. The landing attempt was almost successful until one of the rocket’s engines suddenly shut down prematurely, causing the SN8 to descend much quicker and free fall.
According to SpaceX founder, Elon Musk, they were expecting only a one-third chance of landing success for the SN8 test. Musk took to Twitter to laud the rocket’s successful “switchover from the header tanks and precise flap control to the landing point.” He also explained that the low fuel header tank pressure during landing burn caused the touchdown velocity to rise, which led to “rapid unscheduled disassembly.” However, despite the SN8’s crash and burn episode, SpaceX shared that the test was able to provide the company with the necessary data for its next launches.
The company is already planning to launch more Starship prototypes soon. According to SpaceX, the SN9 is nearly complete and will be undergoing a similar test flight.
Both Starship and the Super Heavy rocket launch system are designed for what Musk envisions as rapid trips between Earth and Mars in the future. They are intended to be fully reusable and will carry more than 100 tons of cargo and passengers. With a height of 50 meters and weighing over 1,400 tons, the Starship is a towering force. Compared to the SN8 prototype’s current design, the final rocket will also double as a six-engine, second-stage booster for the Super Heavy, which is also currently in development.
Starship was first introduced in September 2019 on the 11th anniversary of SpaceX’s first rocket launch and is intended to lower the cost of spaceflight for robotic and crewed missions.
