NASA and SpaceX are gearing up for the 34th Cargo Dragon mission, set to launch from Cape Canaveral Space Force Station on Tuesday evening, weather permitting. This mission marks SpaceX's 34th flight for NASA under the Commercial Resupply Services (CRS) contracts, delivering 6,500 pounds of science and supplies to the International Space Station (ISS). The launch is scheduled for 7:16:31 p.m. EDT (2316:31 UTC) on a northeasterly trajectory. Spaceflight Now will provide live coverage, with a 35% chance of acceptable weather forecast by the 45th Weather Squadron due to a slow-moving front across Florida.
This mission utilizes the Falcon 9 first stage booster B1096, which will return to Landing Zone 40 (LZ-40) for the fourth time, marking the 74th landing for SpaceX since 2015. The Cargo Dragon spacecraft, serial number C209, is on its sixth flight, having previously launched missions CRS-22, -24, -27, -30, and -32. This is a significant milestone as it's the first time a Cargo Dragon spacecraft will launch for a sixth time, though not the first for the Dragon-2 program overall, as the Crew Dragon Endeavour has already flown six times.
The Cargo Dragon will separate from the Falcon 9 second stage about 9.5 minutes into the mission and dock with the ISS at 9:50 a.m. EDT (1350 UTC) on Thursday, May 14. The spacecraft will play catch-up with the ISS during a nearly 50-hour period. Interestingly, the process of loading a space cargo vehicle is not too different from packing for a move or shipping cargo, resembling the preparation of pallets before deployments, according to Jonny Kim, a NASA astronaut.
The launch comes at a busy time in Low Earth Orbit (LEO), with the arrival of the newest cargo spacecraft just two weeks before the next scheduled spacewalk on the Russian segment of the ISS. The U.S. side of the ISS has spacewalks planned for June and August, while the Soyuz MS-29 mission is set to launch on July 14 from the Baikonur Cosmodrome, carrying Cosmonaut and Commander Pyotr Dubrov, alongside fellow cosmonaut Anna Kikina and NASA astronaut Anil Menon. MS-28 will depart less than two weeks after MS-29 arrives, and NASA astronaut Jessica Meir will become the commander of the space station.
The next crewed Dragon mission, Crew-13, will launch in September with NASA astronaut Jessica Watkins, who will become the first active NASA astronaut to fly for a second time on a Dragon spacecraft. The year will also see another Cargo Dragon mission and the launch of the Northrop Grumman Cygnus spacecraft. However, a lingering question is whether Boeing's Starliner spacecraft will make a cargo run to the ISS, with NASA aiming to fly it in 2026 once issues encountered during its 2024 flight are resolved.
In summary, this mission highlights the ongoing efforts of NASA and SpaceX to maintain a steady supply of cargo and supplies to the ISS, while also showcasing the progress and resilience of the Dragon-2 program and the Cargo Dragon spacecraft. The busy schedule in LEO and the upcoming crewed missions underscore the importance of these launches in supporting scientific research and exploration in space.
