A SpaceX Falcon 9 rocket carrying the Dragon spacecraft will launch from Space Launch Complex 40 at Cape Canaveral Space Force Station on Wednesday, May 13, at 6:50 p.m. Eastern Time. The mission, NASA’s Commercial Resupply Services CRS-34, was delayed from an earlier target date but remains on track to deliver critical supplies and scientific equipment to the International Space Station. SpaceX confirmed the new launch window in a statement Monday, citing routine pre-flight checks as the reason for the shift. The Dragon spacecraft will carry about 6,500 pounds of cargo, including water purification hardware and research materials for studying osteoporosis treatments and space weather effects on Earth’s power grids. The launch will be broadcast live on NASA+, Amazon Prime, and the NASA YouTube channel, with updates also available on NASA’s X, Facebook, and Instagram pages. Bill Spetch, a NASA operations manager, said during a Monday teleconference that the mission’s payload includes experiments that could improve understanding of how microgravity affects human bones and how charged particles in space impact Earth’s infrastructure. After a 38-hour flight, the Dragon is expected to autonomously dock with the ISS on Thursday, May 14, at 7:35 a.m. ET. It will remain attached until mid-June, when it will return to Earth and splash down off California’s Pacific Coast. The mission follows SpaceX’s 33rd resupply flight to the ISS in August 2025, which delivered similar scientific equipment. No specific details about the delay’s cause were provided, but SpaceX has a history of adjusting launch dates for technical or weather-related reasons. The launch marks the 34th Commercial Resupply Services mission for SpaceX under its contract with NASA, which began in 2012. The ISS currently hosts seven astronauts, according to NASA’s latest update, though the agency did not specify how the new cargo might affect crew operations.
