![]() ![]() SpaceX ground crews rolled the Falcon 9 rocket and its commercial satellite payload to pad 40 earlier this week, and raised it vertical in the launch mount at pad 40 for final checkouts early Thursday. ![]() They will replace two aging Intelsat satellites, Galaxy 12 and Galaxy 15, that have been in space since 20. The Galaxy 33 and 34 satellites are setting off on 15-year missions to relay C-band video and television programming for media networks and cable providers across North America. An Atlas 5 rocket from United Launch Alliance kicked off the string of launches from Cape Canaveral on Tuesday with a commercial satellite delivery mission for SES. SpaceX’s mission for Intelsat Saturday was also be the third space launch from Florida’s Space Coast in five days. With those missions complete, a few miles south of Kennedy Space Center, SpaceX personnel prepared another Falcon 9 rocket for launch from pad 40 on a commercial flight for Intelsat. PDT 2310 GMT) Wednesday with 52 Starlink internet satellites, just seven hours after the astronaut launch from Florida. Then SpaceX launched a Falcon 9 rocket from Vandenberg Space Force Base in California at 7:10 p.m. The launch Saturday night was the third flight of a Falcon 9 rocket this week, following a Falcon 9 launch at noon EDT (1600 GMT) Wednesday from pad 39A at Kennedy Space Center carrying a four-person crew to the International Space Station. The launch occurred a few minutes after sunset, and with mostly clear skies, spectators enjoyed dazzling views of the Falcon 9 climbs into space at twilight. SpaceX confirmed Friday evening it would not try again to launch the Falcon 9 rocket until Saturday, when the company had a 70-minute launch window available opening at 7:05 p.m. “Tiny helium leak (just barely triggered abort), but we take no risks with customer satellites,” tweeted Elon Musk, SpaceX’ founder and CEO. The launch attempt Thursday night automatically aborted at T-minus 30 seconds after the Falcon 9’s on-board computer, which controls the final minute of the countdown, detected a higher than expected pressure decay rate in the first stage’s helium system. SpaceX aborted a countdown Thursday due to a small helium leak, then called off another launch attempt Friday evening for allow time for additional vehicle checkouts. In addition to recovering the rocket's first stage, SpaceX will also retrieve the payload fairings (aka the rocket's nose cone) which protect the payload as the rocket soars through the atmosphere.A pair of TV broadcasting satellites for Intelsat launched aboard a SpaceX Falcon 9 rocket from Cape Canaveral Saturday at 7:05 p.m. The landing marked the fifth successful touchdown for this particular booster and the 97th overall landing of a Falcon 9 rocket since 2015. ![]() To that end, it has to conduct a "dog-leg" maneuver, meaning it has to change orbital planes after launch, going from a 28.5-degree inclination to a 0.2-degree equatorial orbit. That's because IXPE has to fly over the equator, in a lower orbit, to shield itself from excess radiation exposure that it would receive in higher orbits and to be closer to the ground stations it will be communicating with. That's because it has an ideal water suppression system that will help mitigate the launch effects from the rocket, helping to keep the IXPE satellite safe on its way to orbit.ĭunn, along with Juliana Scheiman, SpaceX's director of civil satellite missions, said that IXPE's intended orbit is really putting the Falcon 9 through its paces. Named "Just Read the Instructions," the drone ship was waiting out in the Atlantic Ocean to catch the booster and haul it back to port to fly again.ĭunn told that typically LSP lets the launch provider pick the launch pad a mission launches from if the company has multiple options, but in this case Pad 39A was the perfect match. This beats SpaceX's record for the most rockets launched in a single year - the company launched 26 in 2020 - with two more launches on the schedule before the end of this year.įollowing a successful liftoff, the rocket's first stage landed on one of the company's three massive drone ships, which serve as floating landing pads. Thursday's pre-dawn flight marks the 131st overall flight of a Falcon 9 and the 28th Falcon 9 to fly in 2021. This veteran launcher, called B1061, has carried eight astronauts into space as part of NASA's first two long-duration missions (Crew-1 and Crew-2), a total of three different Dragon spacecraft, including a cargo mission in August, and a broadband satellite for Sirius XM. 7), an Atlas V rocket blasted off from an adjacent launch pad, carrying a mix of payloads into space for the U.S. Thursday's flight also marks the second rocket launch from Cape Canaveral this week. NASA's Imaging X-ray Polarimetry Explorer (IXPE) is pictured at Ball Aerospace in Boulder, Colorado, on Dec. ![]()
