The Falcon Heavy is listed as capable of placing a 22,200-kilogram payload into geostationary transfer orbit in fully expendable version. Good performance of recent launches allows us to reduce 3 sigma reserve margin,” he said.įor the Falcon Heavy, which SpaceX has said would debut by the end of the year, the listed thrust at liftoff is 5.1 million pounds – “twice any rocket currently flying. He said the increased performance ceilings for both the Falcon 9 and Falcon Heavy are not the result of any design changes, “but higher throttle setting. Subtract 30% to 40% for reusable booster payload.” Musk also said that “the max performance numbers are for expendable launchers. SpaceX founder Elon Musk said in an April 30 Twitter feed that the Falcon 9’s thrust at liftoff, now listed at 1.71 million pounds, will be raised another 11 percent later this year, to 1.9 million pounds of thrust. The pricing and rocket-performance update reflects SpaceX’s latest estimates of what its vehicles can do. Hawthorne, California-based SpaceX has already demonstrated the Falcon 9 Full Thrust’s ability to lift a 5,271-kilogram telecommunications satellite into transfer orbit, with the successful launch in March of the SES-9 satellite. It is the mass penalty, and not the cost of the fuel, that is key performance metric.įor the Falcon 9 Full Thrust, SpaceX said the same rocket that in its fully expendable version can lift up to 8,300 kilograms of payload to geostationary transfer orbit - the destination of most telecommunications satellites, which constitute the vast majority of the commercial market - is limited to 5,500 kilograms in its reusable version. Reserving fuel in the rockets’ first stage and adding landing legs adds weight to the vehicles that cannot be invested the ultimate task of placing payloads into orbit. They should not be used as a guide to low-orbit or Mars missions, SpaceX said. The prices here are for geostationary-orbit launches. For the Falcon Heavy, the performance to GEO is about 2.8x that of the reusable version. The same rocket in fully expendable version can lift 50 percent more payload - 8,300 kilograms. The reusable Falcon 9’s performance to GTO is listed at 5,500 kilograms. SpaceX’s updated price chart shows the significant performance difference between the partially reusable and fully expendable versions of the Falcon 9 Full Thrust and Falcon Heavy rockets.
