The weather forecast remains unchanged for the planned Tuesday, Dec. 21, launch of SpaceX’s 24th commercial resupply services mission to the International Space Station for NASA.

Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 30% chance of favorable weather conditions for Tuesday’s targeted liftoff of a SpaceX Falcon 9 rocket and the company’s Dragon spacecraft from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Less than favorable conditions are expected for the primary launch window early Tuesday morning, with the main concerns associated with this weather being the cumulus cloud rule, thick cloud layer rule, and surface electric field rule.

NASA commercial cargo provider SpaceX is targeting tomorrow at 5:06 a.m. EST, to launch its resupply services mission to the space station. The backup date for launch is Wednesday, Dec. 22, at 4:43 a.m. EST.

At noon today, NASA TV will broadcast a prelaunch news conference from the agency’s Kennedy Space Center in Florida for SpaceX’s 24th commercial resupply services mission. The event will feature representatives from NASA’s International Space Station Program, SpaceX, and the U.S. Space Force Space Launch Delta 45.

Participants include:

Joel Montalbano, manager for the International Space Station Program
Bob Dempsey, Acting Deputy Chief Scientist, International Space Station Program
Sarah Walker, director, Dragon mission management at SpaceX
Arlena Moses, launch weather officer, Cape Canaveral Space Force Station’s 45th Weather Squadron

Live launch coverage will air on NASA Television, the NASA app and the agency’s website, with prelaunch events starting Tuesday at 4:45 a.m. EST. Join us on the blog for live updates, or follow along on NASA TV or the agency’s website for the live launch broadcast.

SpaceX Falcon 9 Rolled to Launch Pad, Weather 30% Favorable for CRS-24 Launch

NASA commercial cargo launch provider SpaceX’s Falcon 9 rocket – with the Dragon atop – was rolled out to the launch pad Sunday morning, Dec. 19, before being raised to a vertical position in preparation for Tuesday’s launch of SpaceX’s 24th commercial resupply services mission to the International Space Station. Liftoff of the Falcon 9 is scheduled for 5:06 a.m. EST.

Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron now predict a 30% chance of favorable weather conditions for Tuesday’s launch, with the cumulous cloud, thick cloud layer, and surface electric field rules remaining the primary weather concerns.

Dragon will deliver a variety of NASA science investigations, including a protein crystal growth study that could improve how cancer treatment drugs are delivered to patients, a handheld bioprinter that could one day be used to print tissue directly onto wounds for faster healing, an investigation from the makers of Tide that examines detergent efficacy in microgravity, and investigations from the Student Payload Opportunity with Citizen Science (SPOCS) program.

About 12 minutes after launch, Dragon will separate from the Falcon 9 rocket’s second stage and begin a carefully choreographed series of thruster firings to reach the space station. Arrival to the station is planned for Wednesday, Dec. 22. Dragon will dock autonomously to the forward-facing port of the station’s Harmony module, with NASA astronauts Raja Chari and Thomas Marshburn monitoring operations from the station.

The spacecraft is expected to spend about a month attached to the orbiting outpost before it returns to Earth with research and return cargo, splashing down off the coast of Florida.

Tune in to NASA TV or the agency’s website for live coverage of mission activities, beginning Monday, Dec. 20, at noon with the prelaunch news conference. Live launch day coverage starts Tuesday at 4:45 a.m. EST.

Weather 40% Favorable for Tuesday’s SpaceX Cargo Resupply Launch

Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 40% chance of favorable weather conditions for Tuesday’s launch, with the cumulous cloud, thick cloud layer, and surface electric field rules being the primary weather concerns.

SpaceX is targeting Dec. 21, at 5:06 a.m. EST, to launch its 24th commercial resupply services mission to the International Space Station for NASA. Liftoff will be from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. SpaceX’s Dragon spacecraft will deliver new science investigations, supplies, and equipment for the international crew.

Some of the NASA science investigations launching as part of Dragon’s 6,500 pounds of cargo include a protein crystal growth study that could improve how cancer treatment drugs are delivered to patients and a handheld bioprinter that could one day be used to print tissue directly onto wounds for faster healing. There are also experiments from students at several universities as part of the Student Payload Opportunity with Citizen Science (SPOCS) program and an investigation from the makers of Tide that examines detergent efficacy in microgravity.

Live coverage will air on NASA Television, the NASA app and the agency’s website, with prelaunch events starting Tuesday at 4:45 a.m. You can also join us here on the blog for live updates.
