The SpaceX Dragon cargo spacecraft approaches the space station for an automated docking loaded with over 7,000 pounds of science experiments, station hardware, and crew supplies on June 9.
A SpaceX Dragon cargo spacecraft splashed down at 10:30 a.m. EDT Friday, June 30, off the coast of Jacksonville, Florida, marking the return of the company’s 28th contracted cargo resupply mission to the International Space Station for NASA. The spacecraft carried approximately 3,600 pounds of valuable scientific experiments and other cargo back to Earth.
Scientific hardware and samples returning on the mission include the GRIP – Dexterous Manipulation in Microgravity chair used in the ESA (European Space Agency)-sponsored neurology experiments GRIP and GRASP (Gravitational References for Sensimotor Performance: Reaching and Grasping). GRIP studies how microgravity affects the manipulation of objects, while GRASP provides further insight into how the central nervous system adapts to the microgravity environment. The experiments have been on the space station almost six years, and the final in-orbit tests were completed in early 2023.

Following commands from ground controllers at SpaceX in Hawthorne, California, the company’s Dragon cargo spacecraft undocked at 12:30 p.m. EDT from the space-facing port of the station’s Harmony module. At the time of undocking the station was flying at an altitude about 260 miles northeast of the Indian Ocean west of Indonesia.
After re-entering Earth’s atmosphere, the spacecraft will make a parachute-assisted splashdown off the coast of Florida on Friday, June 30. NASA will not broadcast the splashdown, but updates will be posted on the agency’s space station blog.
Dragon arrived at the station June 6 as SpaceX’s 28th Commercial Resupply Services mission for NASA, delivering more than 7,000 pounds of research investigations, crew supplies, and station hardware, including two IROSAs, or International Space Station Roll-Out Solar Arrays. The spacecraft was launched June 5 on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

NASA will not broadcast the splashdown, but updates will be posted on the agency’s space station blog.
Bowen began his day in the Kibo laboratory module setting up the NanoRacks CubeSat deployer that will soon be placed into the vacuum of space outside Kibo’s airlock. The deployer will release six different nanosatellites into Earth orbit for Earth observations, communication studies, materials research, and a technology demonstration. NASA Flight Engineer Frank Rubio activated the Astrobee robotic free-flyers during the afternoon and performed software test runs on the devices with assistance from ground controllers.
Hoburg from NASA and Alneyadi from UAE (United Arab Emirates) partnered together in the afternoon for maintenance duties inside the Quest airlock. The duo secured airlock closeout panels and stowage platforms inside Quest.
Human research was a top priority on Wednesday for the cosmonauts working in the orbital outpost’s Roscosmos segment. Flight Engineer Dmitri Petelin assisted Commander Sergey Prokopyev as he attached sensors to himself monitoring how living in microgravity affects his blood pressure and his cardiovascular health. Petelin stowed research hardware then downloaded data collected for a study that observes how the human immune system adapts to long-term weightlessness.
Flight Engineer Andrey Fedyaev set up a camera inside the Poisk module and pointed it out a window to photograph the external condition of the Roscosmos segment of the space station. He also spent some time working on ventilation systems inside the Nauka science module.

Dragon arrived at the station on June 6 packed with over 7,000 pounds of new science experiments, crew supplies, and lab hardware.
While Rubio spent most of Tuesday on Dragon cargo transfers, he also had time for hardware inspections inside the Microgravity Science Glovebox in the afternoon. Bowen swapped out life support components and charged wearable medical monitoring gear. Bowen and Hoburg also spent an hour before lunchtime reviewing Dragon Endeavour crew spacecraft departure procedures.
