SpaceX Dragon Delivers New Science Experiments to International Space Station
The SpaceX Dragon spacecraft successfully docked with the International Space Station (ISS) on May 17, 2026, at 6:37 a.m. EDT. This marks the 34th commercial resupply mission by SpaceX for NASA. The Dragon carried nearly 6,500 pounds of cargo, including food, supplies, and scientific equipment for the Expedition 74 crew. Among the new experiments delivered are projects to assess the effectiveness of Earth-based simulators in replicating microgravity, a bone scaffold made from wood for potential osteoporosis treatments, and tools to study changes in red blood cells and the spleen in space. Additionally, the mission includes an instrument to study charged particles around Earth, which could impact power grids and satellites, and another to measure sunlight reflected by Earth and the Moon. The mission launched on May 15 from Cape Canaveral Space Force Station in Florida aboard a SpaceX Falcon 9 rocket.
