“SpaceX will learn from its mistakes and hopefully we will see quicker iterations once that first test flight is off the ground and they get the data they need to improve for the next time.” “We should expect failures of brand-new rockets,” says Laura Forczyk, a space analyst and executive director of Astralytical, a space consulting firm. “Starship just experienced what we call a rapid unscheduled disassembly, or a RUD, during ascent,” Insprucker said during the livestream.Įven though the flight only lasted a few minutes, it was a key milestone for the private spaceflight company, which now has a wealth of data it can use to finetune the vehicle and-it hopes-ensure that the next flight lasts longer and soars far higher. As a result, the whole assemblage spun out of control and fell to pieces after reaching a maximum altitude of around 24 miles (39 kilometers). Instead, Super Heavy and Starship were unable to disentangle themselves. “All of these engines are going to be working at the limit of what the materials can handle,” he added.ĭespite the smooth liftoff, something went awry at stage separation when the two vehicles should have parted ways to allow Starship to soar onward on a one-hour flight that would have ended with the vehicle splashing into the ocean near Hawaii. “You have this very large number of rocket engines firing in parallel, and it is unlikely that everything will go smoothly with all of them at the same time,” Paulo Lozano, a space propulsion expert at the Massachusetts Institute of Technology, told Scientific American before the test flight. That alone was a feat, because no rocket has ever carried so many engines. (During the livestream, SpaceX engineer Kate Tice said that three engines appeared not to be firing but didn’t provide any details about the issue video of the rocket during its ascent suggested up to five engines were inactive.) During the flight, most-although apparently not all-of Super Heavy’s 33 engines fired successfully for several minutes. Starship and Super Heavy have each flown before, but today’s flight marked the first time they launched as a unit. Both components are designed to be reusable, and SpaceX aspires to eventually top off Starship’s fuel tanks in orbit to power even more adventurous itineraries. The launch system is composed of the 164-foot-tall, missile-shaped Starship vehicle and the 226-foot-tall Super Heavy booster it sits upon. Starship sits at the heart of SpaceX’s dreams of sending humans to the moon and Mars and is also designed to ferry countless tourists-and thousands of the company’s Starlink Internet satellites-into orbit. “There are lots of different ways to succeed and fail with these kinds of tests,” says Teasel Muir-Harmony, a historian of science at the National Air and Space Museum in Washington, D.C. That’s because the history of spaceflight is riddled with programs that have learned from explosive mistakes during test flights to reach their goals. “Starship gave us a rather spectacular end to what was truly an incredible test,” said John Insprucker, a SpaceX engineer who provided commentary during a livestream of the launch.ĭespite the abrupt ending, neither the company nor industry observers see the flight as a failure. ![]() For a few moments, Starship-and its goal of revolutionizing space access-appeared to be soaring smoothly, but the harsh reality of rocketry soon kicked in, and an anomaly caused the massive launch vehicle to disintegrate in a fireball. ![]() local time at the southernmost tip of Texas, SpaceX’s Starship launch system-the largest, most powerful rocket yet built-roared to life in a milestone liftoff that sent it rising above the Gulf of Mexico. The skies over Texas have never seen a fireball quite like this before.
