SpaceX Dragon CRS-34 hauls 6,500 lb of science to the ISS

After two weather scrubs, SpaceX successfully launched its CRS-34 cargo mission to the International Space Station from Florida on 15 May 2026. Dragon carried about 6,500 pounds (2,950 kg) of supplies, hardware, and scientific experiments, with autonomous docking to the forward port of the Harmony module scheduled for 17 May around 7:05 a.m. EDT.

CRS-34 is the sixth spaceflight for this particular Dragon capsule — a new reuse record for a SpaceX cargo craft, and another data point in the slow normalisation of fully reusable orbital logistics.

On board: NASA biology and materials experiments, station hardware, and a fresh round of crew supplies. ISS science continues to lean heavily on rapid, frequent commercial resupply: more flights per year, each carrying smaller payloads, has quietly become the dominant model for low-Earth-orbit research.
