This evening, SpaceX is set to launch nearly 6,000 pounds of essential supplies, food, and scientific experiments to the International Space Station (ISS) aboard a Falcon 9 rocket. The launch will take place from Florida, on Launch Complex 39A at Kennedy Space Center, with liftoff scheduled for 9:29 p.m. ET, timed precisely to align the cargo Dragon capsule with the ISS’s orbit.

The 45th Weather Squadron currently forecasts a 70% chance of favorable launch conditions, with possible concerns around cumulus clouds, winds, and precipitation. If postponed, the next launch window opens Wednesday, Nov. 5, at 9:06 p.m. ET.

This mission marks a new journey for the Falcon 9 first-stage booster, B1083, a veteran of multiple missions, including crewed launches. After stage separation, B1083 will land at Cape Canaveral Space Force Station’s Landing Zone 1.

SpaceX’s Dragon capsules have completed 31 resupply missions for NASA, with this Dragon, C208, previously flying four successful missions. Upon docking with the ISS’s Harmony module, the Dragon will deliver nearly 6,000 pounds of items, including the Coronal Diagnostic Experiment to study solar wind formation, Antarctic moss for plant studies, and devices for testing metal welding in microgravity.

This Dragon will undock in December for a planned splashdown off the Florida coast, concluding the CRS-31 mission and bringing back data and equipment for further study.
