A SpaceX Cargo Dragon spacecraft, designated C209, successfully launched atop a Falcon 9 rocket from Cape Canaveral Space Force Station on May 15, 2026. This mission marked a significant milestone as it was the third attempt to launch due to adverse weather conditions earlier in the week.
The launch occurred at 6:05 p.m. EDT (2205 UTC), delivering approximately 6,500 pounds of science and supplies to the International Space Station (ISS). This mission, known as CRS-34, represents SpaceX’s 34th mission for NASA under the Commercial Resupply Services (CRS) contracts.
Launch Delays and Weather Conditions
Prior to the successful launch, two attempts were thwarted by a slow-moving weather front that brought thick clouds and thunderstorms to central Florida. On Wednesday, the countdown reached T-28 seconds before a hold was called due to lightning-triggering anvil clouds near the launch pad. The launch was rescheduled for Friday, allowing ground crews to reload ‘late load’ items with a short shelf life.
With high pressure settling over central Florida, weather forecasts indicated a 90-percent chance of acceptable conditions for the launch, with minimal risk of violating the cumulus cloud rule.
Mission Details and Booster Recovery
After liftoff, the Falcon 9 rocket followed a northeasterly trajectory, aiming for a rendezvous with the ISS. Less than eight minutes post-launch, the first stage booster successfully returned to Landing Zone 40 (LZ-40), adjacent to the launch pad, marking the fourth booster recovery at this site and the 108th on-shore landing across SpaceX’s four launch pads since 2015.
The CRS-34 mission utilized Falcon 9 first stage booster B1096, which has flown six times prior, including missions for NASA and other payloads. The Cargo Dragon spacecraft, C209, also has a notable history, having previously launched for missions CRS-22, -24, -27, -30, and -32. This mission marks the first occasion that a Cargo Dragon spacecraft has been launched for a sixth time, although the Crew Dragon Endeavour has also achieved this milestone.
Upcoming Docking with the ISS
Approximately 9.5 minutes into the mission, the Cargo Dragon separated from the Falcon 9 second stage, initiating a nearly 37-hour orbital chase to rendezvous with the ISS. The spacecraft is scheduled to dock with the station at approximately 7:05 a.m. EDT (1105 UTC) on Sunday, May 17.
