SpaceX\u2019s latest crewed Dragon mission to the ISS is the fastest on record yet. Its Crew-13 Mission for NASA launched and arrived at the International Space Station (ISS) in just under 8 hours (7 hours and 55 minutes).<\/p>\n
By all accounts, that makes it the fastest delivery any American spacecraft has managed in history. According to NASA, the previous record was about 12 hours and 33 minutes back in November of 2024.<\/p>\n
This was another SpaceX Dragon cargo capsule mission during the company\u2019s CRS-31 resupply flight<\/a>. As for manned missions, the previous record was in August 2025 by another Crew-11 mission at 14 hours and 43 minutes.<\/p>\n So how was the record-breaking feat achieved? According to NASA, luck certainly played a role. \u201cWe got lucky this time,\u201d Julianna Scheiman<\/a>, director of NASA science and SpaceX\u2019s Dragon program, said at Crew-13\u2019s post-launch press conference today.<\/p>\n \u201cThe space station was in an opportune spot in space, and the orbital mechanics, the physics of it all, worked out for it to be the shortest launch-to-docking time we\u2019ve had to date,\u201d she said. \u201cThis is close to the fastest it could be,\u201d she added.<\/p>\n Record-breaking ISS supply time<\/p>\n The ISS orbits the Earth at around 28,000 kph, completing an orbit about every 90 minutes. For this reason, you can\u2019t just launch a rendezvous spacecraft and fly straight to it.<\/p>\n In order to dock, a craft needs to enter the same orbital plane, have enough velocity to catch up, and be able to carefully maneuver into position. Sounds simple on paper, but this is a very tricky thing to achieve.<\/p>\n The most crucial factor is where the ISS is along its orbit when Dragon launches. The spacecraft must launch when the station\u2019s orbital plane passes over the launch site. <\/p>\n But it also needs the ISS to be at a favorable point along that orbit. If the phasing is right, Dragon can begin catching the station almost immediately.<\/p>\n But that\u2019s only part of the story. The ISS is already traveling at a fair pace in orbit; to this end, any spacecraft needs to also catch up with it. To help out here, Mission controllers tend to put craft like the Dragon<\/a> in a slightly lower orbit.<\/p>\n Being closer to Earth, this enables the craft to \u201chack\u201d the geometry to gradually catch up with the ISS. With each orbit taking around 90 minutes, even just a handful will easily add hours to a trip.<\/p>\n Location, location, location<\/p>\n In this case, the Crew-13 happened to launch when the geometry was unusually favorable. The ISS was positioned such that Dragon could get into orbit and begin catching it almost immediately.<\/p>\n
