Starship launched from Boca Chica, Texas.
SpaceX
SpaceX’s Starship, the largest rocket ever, successfully completed its fourth test flight, with the first and second stages completing their missions as planned and each landing in different oceans.
Following liftoff from the SpaceX facility in Boca Chica, Texas, at 7:50 a.m. local time, one of the 33 Raptor engines on Super Heavy’s first stage failed to ignite. Despite this, the rocket continued into space and the two stages separated cleanly.
Super Heavy splashed down on schedule about seven minutes after liftoff, close to the launch site in the Gulf of Mexico. After plummeting to Earth from an altitude of more than 100 kilometers, the booster’s engines ignited normally and it slowed from more than 4,000 kilometers per hour to hover just a few meters above the sea level, but then the live feed cut out and it plunged into the ocean.
Meanwhile, Starship reached an orbit at an altitude of more than 200 kilometers and traveled at a speed of more than 27,000 kilometers per hour. During its descent to Earth, about 60 kilometers above the surface, SpaceX’s livestream footage showed visible damage to one of its four control fins and what appeared to be a cracked camera lens. As it reached the Indian Ocean, it appeared to hover before plummeting into the water.
This fourth test flight focused on returning Starship from orbit after it had reached space for the first time in the previous test. SpaceX opted to perform a “soft splashdown” at sea, as landing on land is currently considered too risky. Instead, the craft would use its engines to slow its descent, align itself as if it were landing on a base, and then gently splash down on the water.
Eventually, the hope is that spacecraft will be able to be refurbished and reused by returning to land from space, as SpaceX already does with its Falcon 9 rocket.
Today’s launch marks the company’s fourth Starship launch and includes software and hardware upgrades, as well as changes to launch procedures based on lessons learned from previous tests. In the first test in April of last year, the first and second stages exploded before separating, and in another test in November, the second upper stage reached space but stopped transmitting data and self-destructed, and the first stage exploded shortly after separation.
SpaceX’s third Starship test flight on March 14 was at least partially successful, reaching space, conducting a fuel transfer test, and flying farther and faster than ever before, but the spacecraft lost control during the flight and failed to make a planned soft landing.
