SpaceX\u2019s gargantuan deep-space rocket system, Starship, safely lifted off Saturday morning but ended prematurely with an explosion and a loss of signal. <\/p>\n
The Super Heavy booster and Starship spacecraft successfully separated after liftoff, as the Starship lit up its engines and pushed away. That process ended up destroying the Super Heavy booster, which erupted into a ball of flames over the Gulf of Mexico. But the Starship spacecraft was able to briefly continue its journey. <\/p>\n
The Starship system made it much farther into flight than the first attempt in April. The rocket and spacecraft lifted off the launchpad at 8 a.m. ET, with the Super Heavy booster igniting all 33 of its Raptor engines. Even during ground tests, SpaceX has had a hard time getting all of those engines, clustered together at the base of the rocket, to power on consistently at the same time. <\/p>\n
The Starship upper stage had begun its trip Saturday morning <\/strong>strapped to the top of the Super Heavy first stage, a 232-foot-tall (70.7-meter-tall) rocket. About two and a half minutes after roaring to life and vaulting off the launchpad, the Super Heavy booster expended most of its fuel, and the Starship spacecraft fired its own engines and broke away. <\/p>\n The Starship spacecraft used its own six engines to continue propelling itself to faster speeds. SpaceX aimed to send the spacecraft to near orbital velocities, typically around 17,500 miles per hour (28,000 kilometers per hour). Starship climbed to an altitude of about 93 miles (150 kilometers) above the Earth\u2019s surface, reaching the edge of space. <\/p>\n The US government considers 50 miles (80 kilometers) above Earth\u2019s surface the edge of outer space. Internationally, the K\u00e1rm\u00e1n line, located 62 miles (100 kilometers) above sea level, is often used to mark the boundary between our planet and space \u2014 but there\u2019s a lot of\u00a0gray area. <\/p>\n The SpaceX team awaited acquisition of signal from the spacecraft, but shared during the livestream that the \u201csecond stage was lost.\u201d <\/p>\n \u201cThe automated flight termination system on second stage appears to have triggered very late in the burn as we were headed down range out over the Gulf of Mexico,\u201d aerospace engineer John Insprucker said. <\/p>\n The flight termination system is essentially a self-destruct feature that SpaceX engaged to prevent the Starship from traveling off course. <\/p>\n \u201cThe booster experienced a rapid unscheduled disassembly shortly after stage separation while Starship\u2019s engines fired for several minutes on its way to space,\u201d SpaceX shared on X, formerly known as Twitter. \u201cWith a test like this, success comes from what we learn, and today\u2019s test will help us improve Starship\u2019s reliability as SpaceX seeks to make life multiplanetary.\u201d <\/p>\n The Federal Aviation Administration, which licensed the Starship\u2019s test flight today, issued a statement after the test flight. <\/p>\n \u201cA mishap occurred during the SpaceX Starship OFT-2 launch from Boca Chica, Texas, on Saturday, Nov. 18. The anomaly resulted in a loss of the vehicle. No injuries or public property damage have been reported,\u201d according to an FAA spokesperson. <\/p>\n The agency will conduct a mishap investigation to determine the root cause of the loss of Starship, which is standard procedure. <\/p>\n \u201cA return to flight of the Starship Super Heavy vehicle is based on the FAA determining that any system, process, or procedure related to the mishap does not affect public safety,\u201d according to the FAA. <\/p>\n It took more than four months for the FAA to complete the last mishap investigation after Starship\u2019s test flight in April. <\/p>\n NASA is investing up to $4 billion in the rocket system with the goal of using the Starship capsule to ferry astronauts to the lunar surface for its Artemis III mission, currently slated to take off as soon as 2025. <\/p>\n The endeavor is aiming to return humans to the moon for the first time in five decades, and the successful completion of this test flight would have brought the US space agency and SpaceX one step closer to that goal. <\/p>\n \u201cCongrats to the teams who made progress on today\u2019s flight test,\u201d NASA Administrator Bill Nelson shared on X. \u201cSpaceflight is a bold adventure demanding a can-do spirit and daring innovation. Today\u2019s test is an opportunity to learn \u2014 then fly again. Together @NASA and @SpaceX will return humanity to the Moon, Mars & beyond.\u201d <\/p>\n \u201cEach test represents a step closer to putting the first woman on the Moon with the #Artemis III Starship human landing system. Looking forward to seeing what can be learned from this test that moves us closer to the next milestone,\u201d Jim Free, NASA associate administrator for exploration systems development, shared on X. <\/p>\n The failure could spell significant delays for Starship\u2019s development and the key missions lined up on its manifest, most notably NASA\u2019s Artemis III mission. The US space agency tapped Starship in 2021 to serve as the lunar lander for that mission. <\/p>\n The root cause of the Starship rocket\u2019s failure on Saturday was not immediately clear. <\/p>\n But the booster explosion occurred after a phase called \u201chot staging\u201d that SpaceX tried for the first time Saturday. <\/p>\n The method was used to separate the Starship spacecraft and Super Heavy rocket after liftoff. <\/p>\n Almost all rockets go through a process during launch called \u201cstage separation,\u201d in which the bottommost rocket booster diverges from the rest of the rocket or spacecraft. <\/p>\n When SpaceX launches its workhorse Falcon 9 rocket, for example, the first-stage booster \u2014 or the bottommost portion of the rocket \u2014 breaks away from the upper part of the rocket less than three minutes into flight. The Falcon 9 does so using\u00a0pneumatic pushers that are housed within the rocket\u2019s interstage, or black band around the center. <\/p>\n Instead, the Starship spacecraft fired up its own engines to push itself away from the Super Heavy booster \u2014 and it\u2019s essentially separation by blunt force trauma. <\/p>\n It marked a crucial moment for SpaceX, as hot staging was expected to be \u201cthe riskiest part of the flight,\u201d SpaceX CEO Elon Musk said in October. <\/p>\n SpaceX had already said it would consider the mission a success if Starship made it past hot staging. <\/p>\n But after hot staging, the Super Heavy booster began tumbling out of control and exploded over the Gulf of Mexico just moments later. SpaceX had hoped to reignite the Super Heavy\u2019s engines and guide it to a controlled landing. <\/p>\n \u201cWe did know that hot staging was going to be incredibly dynamic,\u201d said Kate Tice, senior manager of SpaceX\u00a0Quality Systems Engineering, during the livestream. We knew that there was a chance that the booster would not survive, but we\u2019re going to take that data and figure out how we can make the booster better for the next hot stage.\u201d <\/p>\n Initially, the Starship spacecraft continued moving along after separation. <\/p>\n About eight minutes after liftoff, cheers could be heard echoing throughout mission control as the Starship was approaching the end of its engine burn \u2014 putting it on a path toward Earth\u2019s orbit. But nine minutes after launch, SpaceX made it clear that it lost video signal with Starship. <\/p>\n And about 11.5 minutes into the flight, the company confirmed it had lost data, indicating Starship wasn\u2019t flying as planned. Then, the spacecraft\u2019s flight termination system was triggered to prevent it from veering off course, bringing an early end to the test flight. <\/p>\n If all had gone according to plan, Starship would have continued accelerating toward space. The Starship spacecraft was then slated to complete nearly one full lap of Earth, aiming to splash down in the Pacific Ocean near Hawaii. <\/p>\n The destruction of the vehicle shortly after liftoff was reminiscent of the Starship\u2019s first launch attempt in April. During that test flight, several of the Super Heavy\u2019s engines unexpectedly powered off and the rocket began spiraling out of control just minutes after liftoff. SpaceX was forced to trigger the system\u2019s self-destruct feature, blowing up both stages over the Gulf of Mexico. <\/p>\n SpaceX took several months to recover from the April mishap. The company was forced to rebuild its launch site, which had been torn to pieces by the sheer force of the rocket powering its engines. The company also implemented upgrades to both the Starship spacecraft and the Super Heavy booster. <\/p>\n SpaceX typically embraces fiery mishaps in the early stages of rocket development. The company has long maintained that it can learn how to build a better rocket more quickly and cheaply by flying \u2014 and occasionally exploding \u2014 early prototypes rather than relying solely on ground testing and computer modeling. <\/p>\n After April\u2019s explosive first test flight, SpaceX noted \u201csuccess comes from what we learn, and we learned a tremendous amount.\u201d <\/p>\n\n SpaceX\u2019s gargantuan deep-space rocket system, Starship, safely lifted off Saturday morning but ended prematurely with an explosion and a loss of signal.
