“Ship landings are not needed for flexibility or to save fuel costs,” Musk posted on Twitter. High-energy Falcon 9 flights, like the next launch scheduled for early February from Florida with the SES 9 television broadcasting craft, must reach higher speeds during the first stage’s nearly three-minute burn, leaving no fuel to turn around and fly back to the launch site. He added that a similar problem on a landing back on the coast would have probably had the same result. “Touchdown speed was ok, but a leg lockout didn’t latch, so it tipped over after landing.” “However, that was not what prevented (Sunday’s landing) being good,” Musk tweeted. Underwater thrusters on SpaceX’s drone ships keep the vessels in place, but the barge can spin and is susceptible to rocking from waves. “Similar to an aircraft carrier vs land: much smaller target area, that’s also translating & rotating.” Debris from the Falcon 9 rocket after Sunday’s landing attempt. “Definitely harder to land on a ship,” Musk tweeted Sunday. Officials admit landing on a ship presents more challenges the returning than booster to land, but if SpaceX eventually aims to recover and reuse all its Falcon 9 boosters, the barge is essential. No such problems haunted the Falcon 9 rocket’s descent Sunday, and officials said the landing would have been successful without the broken leg. The failed landing makes SpaceX 0-for-3 when targeting touchdowns on the ocean-going barge, but Sunday’s try came closer to sticking the landing than earlier attempts.Įngineers blamed the explosive crash landing of a Falcon 9 booster in January 2015 on insufficient hydraulic fluid for the rocket’s steering fins, and a first stage made a hard landing in April 2015 after a throttle valve on the landing engine became stuck. 3 failed to latch, and the landing gear crumpled as the booster settled on the ship’s deck.Ī video posted to Instagram by Musk showed the rocket falling over and breaking apart in a fireball, and a photo released by SpaceX showed wreckage strewn across the platform positioned about 170 miles (280 kilometers) south of Vandenberg in the Pacific Ocean. The rocket was right on course - just 4.3 feet (1.3 meters) off center, SpaceX said - but a collet on leg No. The Falcon 9 first stage descends to a soft landing on SpaceX’s drone ship in the Pacific Ocean on Sunday. The rocket’s center engine, one of nine Merlin engines on the Falcon 9 first stage, fired to put on the brakes just as the vehicle approached the drone ship named “Just Read the Instructions” after a starship featured in science fiction writer Iain Banks’ novels. and European science institutions, then flipped around and slowed down before reaching the landing platform. The booster jettisoned from the Falcon 9’s upper stage, which continued into orbit with the Jason 3 oceanography satellite for U.S. The Falcon 9’s first stage, which stands 14 stories tall and measures 12 feet (3.7 meters) in diameter, flew on course to the drone ship Sunday after liftoff from Vandenberg Air Force Base in California. SpaceX’s first rocket landing attempt on shore in December was successful, giving the company a triumph to close the year after a launch failure in June grounded the Falcon 9 for nearly six months. It was SpaceX’s third attempt to land a Falcon 9 booster on the company’s drone ship positioned downrange in the ocean. The rocket landings have become a regular fixture on SpaceX launches as the California-based company tries to perfect techniques to make the Falcon 9 first stage reusable, a goal SpaceX founder and chief executive Elon Musk says is vital to reducing the cost of spaceflight. One of four landing legs mounted to the base of SpaceX’s Falcon 9 booster failed to engage on the rocket’s final descent to a barge in the Pacific Ocean on Sunday, leaving wreckage scattered on the football field-sized deck of the landing ship after an otherwise successful launch with an ocean research satellite. Root cause may have been ice buildup due to condensation from heavy fog at liftoff.Ī video posted by Elon Musk on at 7:07pm PST Falcon lands on droneship, but the lockout collet doesn’t latch on one the four legs, causing it to tip over post landing.
