The weather forecast has dipped slightly for the planned Saturday, Aug. 28, launch of SpaceX’s 23rd commercial resupply services mission to the International Space Station.

Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 50% chance of favorable weather conditions for Saturday’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. An instantaneous window opens at 3:37 a.m. EDT.

The primary weather concerns are cumulus cloud rule and flight through precipitation. The most recent forecast represents a 10% drop in favorable conditions from Wednesday’s predicted launch weather.

Dragon will be filled with supplies and payloads, including critical materials to directly support dozens of the more than 250 science and research investigations that will occur during Expeditions 65 and 66. Upon Dragon’s arrival – slated for Sunday, Aug. 29 – NASA astronauts Shane Kimbrough and Megan McArthur will monitor operations while the spacecraft autonomously docks to the orbiting laboratory’s Harmony module.

The Dragon spacecraft for SpaceX’s 23nd commercial resupply services mission is now ready for its flight to the International Space Station.

On Friday, Aug. 20, teams transported the spacecraft from SpaceX’s processing facility at Cape Canaveral Space Force Station into the hangar at nearby Kennedy Space Center’s Launch Complex 39A, where it was attached to the Falcon 9 rocket two days later.

The rocket – with Dragon atop – was then rolled out to the launch pad Tuesday, Aug. 24, and raised to a vertical position this morning, Aug. 25, in preparation for Saturday’s launch. Liftoff of the Falcon 9 is scheduled for 3:37 a.m. EDT. Dragon will deliver a variety of NASA investigations, including one that will determine if metabolites from grape skins and seeds used in wine-making could help prevent and treat osteoporosis.

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 orbiting laboratory is planned for Sunday, Aug. 29. The spacecraft is expected to spend about a month attached to the space station before it splashes down off the coast of Florida, returning with research and cargo.

Tune in to NASA TV or the agency’s website for live coverage of mission activities, beginning Friday at noon with the prelaunch news conference. Launch day coverage, which also can be found here, starts Saturday at 3:15 a.m. EDT.

Weather 60% Percent Favorable for Saturday’s Launch

Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 60% chance of favorable weather conditions for Saturday’s launch from the Space Coast, with the cumulus cloud rule and flight through precipitation serving as the primary weather concerns.

NASA commercial cargo provider SpaceX is targeting Aug. 28, at 3:37 a.m. EDT, to launch its 23rd commercial resupply services mission to the International Space Station. 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.

One experiment will test an implantable, remote-controlled drug delivery system that will utilize a new research facility aboard the orbiting laboratory. Upon Dragon’s arrival – slated for Sunday, Aug. 29 – NASA astronauts Shane Kimbrough and Megan McArthur will monitor operations while the spacecraft autonomously docks to the orbiting laboratory’s Harmony module.

Live coverage will air on NASA Television, the NASA app and the agency’s website, with prelaunch events starting Friday, Aug. 27. Beginning Saturday at 3:15 a.m., join us here on the blog for live coverage, and follow along on NASA TV or the agency’s website for the live launch broadcast.

NASA Tests Ways to Reduce Stress in Plants Growing in Space

When astronauts embark on long-duration missions in the future, crews will grow food to supplement what they can bring with them. More than 20 years of continuously living and working in space aboard the International Space Station has provided many opportunities for crews and researchers to observe the challenges of growing plants in the stressful conditions of microgravity.

One experiment on NASA SpaceX’s 23rd Commercial Resupply Services mission to the space station will help determine the effect of plant stress responses to the microgravity environment. The Advanced Plant Experiment-08 (APEX-08) will grow Arabidopsis thaliana, a plant scientists routinely use for research. The study includes making genetic alterations that elicit a response in the pool of polyamines, a group of organic compounds that modulate plant responses to environmental stress.
