On 21 March 2024, SpaceX CRS-30 lifted off carrying NASA’s BurstCube CubeSat. After later release from the International Space Station, BurstCube was designed to detect and localize short gamma-ray bursts and send rapid alerts to Earth, enabling follow-up by other observatories and multimessenger campaigns focused on neutron-star mergers.

On 21 March 2024, CRS-30’s Dragon cargo spacecraft launched on a Falcon 9 toward the International Space Station, starting phasing burns for a planned docking and carrying science, supplies, and hardware. The flight showed how routine resupply missions sustain experiments, crew provisions, and ongoing maintenance for the orbiting laboratory.

On 21 March 2024, the Soyuz 71S launch from Baikonur was scrubbed on the pad. NASA stated that astronaut Tracy Dyson, cosmonaut Oleg Novitskiy, and participant Marina Vasilevskaya were safe along with the spacecraft, showing how late scrubs can delay crew rotations and require fast replanning of station timelines and vehicle traffic.
