NASA’s 33rd SpaceX resupply mission successfully launched from Cape Canaveral on August 24, 2025, delivering over 5,000 pounds of supplies and scientific experiments to the International Space Station (ISS). The launch occurred at 2:45 a.m. EDT, using a Falcon 9 rocket, marking another milestone in NASA’s ongoing collaboration with SpaceX.

The mission aims to support the ISS with essentials and cutting-edge experiments, including 3D printing metal parts and bioprinting tissue in microgravity. These technologies are pivotal for future Artemis lunar missions and potential human exploration of Mars, according to acting NASA Administrator Sean Duffy. Among the scientific cargo are bone-forming stem cells, bioprinted liver tissue, and materials to create medical implants, all crucial for advancing research in microgravity environments.

Dragon, the SpaceX spacecraft, is set to autonomously dock with the ISS’s Harmony module at approximately 7:30 a.m. EDT on August 25. The spacecraft will remain docked until December, when it will return to Earth with research findings, splashing down off the California coast.

In addition to cargo delivery, Dragon will demonstrate a reboost of the ISS, using an independent propellant system to maintain the station’s altitude. This capability was first demonstrated during NASA’s SpaceX 31st resupply mission in November 2024, marking a significant advancement in sustaining the ISS’s operations.

This mission exemplifies NASA’s commitment to innovation and exploration, paving the way for future deep-space missions while delivering tangible benefits to life on Earth.
