Robotic flight controllers released the SpaceX Dragon cargo spacecraft from the International Space Station’s robotic arm at 12:38 p.m. EDT, and Expedition 56 Serena Auñon-Chancellor of NASA is monitoring its departure.

Dragon’s thrusters will be fired to move the spacecraft a safe distance from the station before SpaceX flight controllers in Hawthorne, California, command its deorbit burn about 5:23 p.m. The capsule will splashdown about 6:17 p.m. in the Pacific Ocean, where the SpaceX recovery team will retrieve the capsule and its more than 3,800 pounds of cargo, including a variety of technological and biological studies.

NASA and the Center for the Advancement of Science in Space (CASIS), the non-profit organization that manages research aboard the U.S. National Laboratory portion of the space station, will receive time-sensitive samples and begin working with researchers to process and distribute them within 48 hours of splashdown.

Dragon is the only space station resupply spacecraft currently capable of returning cargo to Earth, and this was the second trip to the orbiting laboratory for this spacecraft. SpaceX launched its 15th NASA-contracted commercial resupply mission to the station June 29 from Space Launch Complex 40 from Cape Canaveral Air Force Station in Florida on a Falcon 9 rocket that also previously launched NASA’s TESS mission to study exoplanets.

The SpaceX Dragon cargo craft is packed with science and hardware ready for return to Earth on Friday. NASA is also introducing a team of astronauts who will soon fly Boeing and SpaceX vehicles to the International Space Station.

The Expedition 56 crew has finished loading Dragon with sensitive research results and station gear for analysis and refurbishment back on Earth. Space station officials from around the world gave the “go” on Thursday for Dragon’s release from the orbital complex.

Mission controllers, with astronaut Serena Auñón-Chancellor monitoring, will command the Canadarm2 robotic arm to release Dragon at 12:37 p.m. EDT Friday. Splashdown in the Pacific Ocean will occur less than six hours later under a trio of huge parachutes off the coast of Baja California.

NASA will introduce Friday at 11 a.m. on NASA TV new astronauts assigned to spaceflights launching from the United States for the first time since July 8, 2011. NASA’s Commercial Crew Program is partnering with Boeing and SpaceX to launch humans on U.S.-built spaceships from Kennedy Space Center on test flights to the space station.

The International Space Station Partners and mission managers polled “go” for tomorrow’s release of the SpaceX Dragon cargo craft for its deorbit and splashdown in the Pacific Ocean to wrap up the CRS-15 mission.

With favorable weather conditions forecast in the splashdown zone, Dragon’s hatch will be closed early Friday around 3 a.m. Central time. Robotic ground controllers will then use the Canadarm2 robotic arm to detach Dragon from the Earth-facing port of the Harmony module around 5:30 a.m. Central time and will maneuver Dragon into the release position.

With Expedition 56 Flight Engineer Serena Auñón-Chancellor of NASA monitoring Dragon’s systems, the ground controllers will release Dragon from Canadarm2 at 11:37 a.m. Central time. After its release, Dragon will conduct a series of “departure” burns to move to a safe distance away from the station.

Several hours later, at 4:23 p.m. Central time, SpaceX flight controllers at Hawthorne, California will command Dragon’s engine to fire for 12 minutes and 53 seconds in the deorbit burn that will enable Dragon to slip out of orbit for its descent back to Earth.

Dragon’s parachute-assisted splashdown is scheduled at 5:17 p.m. Central time, 3:17 p.m. Pacific time, about 410 miles southwest of Long Beach, California. It will take about two days for Dragon to be brought back to port for its cache of cargo and scientific experiments to be unloaded.

The Expedition 56 crew has nearly completed loading the SpaceX Dragon resupply ship with cargo for retrieval back on Earth this Friday. The orbital residents are also busy with an intense day of space research and Russian spacewalk preparations.

Dragon is due to be released Friday at 12:37 p.m. EDT from the International Space Station carrying several tons of experiment results and orbital lab hardware. The crew has been packing the crucial research samples this week inside specialized, portable freezers onboard the commercial space freighter.

SpaceX technicians will pick up Dragon with its precious cargo after it splashes down in the Pacific Ocean and return to shore in southern California. Scientists and engineers will then begin the process of analyzing the critical space science and refurbishing station hardware.

Astronauts Serena Auñón-Chancellor and Alexander Gerst spent Wednesday morning helping doctors understand how living in space impacts the human eye. They are exploring the hypothesis that upward fluid shifts in the body caused by microgravity increases pressure on the brain possibly pushing against the eyes. This may affect the shape of the eye and permanently affect vision.

Cosmonauts Oleg Artemyev and Sergey Prokopyev are getting ready for a spacewalk on Aug. 15. The duo reviewed the translation paths to their work sites on the outside of the station’s Russian segment. During the near seven-hour excursion, the spacewalkers will hand-deploy four tiny satellites, install antennas and cables on the Zvezda service module and collect exposed science experiments.

Numerous microgravity investigations are wrapping up this week onboard the International Space Station. The Expedition 56 crew is carefully packing the research results and science gear inside the SpaceX Dragon cargo craft for return to Earth on Friday.

A host of life science studies being returned aboard Dragon looked at cancer therapies, gut microbes, and a variety of other biological phenomena. Samples collected from those studies, including the experiment hardware housing the research, are being transferred from the station and stowed inside the Dragon.

The AngieX Cancer Therapy investigation is completing its run today with NASA astronaut Serena Auñón-Chancellor finalizing research operations inside the Microgravity Science Glovebox. The experiment tested a treatment that targets tumors and the resulting samples are being stowed inside Dragon science freezers.

Rodents studied for the Rodent Research-7 experiment to understand how microbes interact with the gut in space are being returned Friday. Biological samples observed in July for the Micro-11 human reproduction study are also being cold stowed aboard Dragon.

SpaceX technicians will retrieve Dragon loaded with the Earth-bound cargo when it splashes down in the Pacific Ocean Friday afternoon. Once the cargo craft reaches port, personnel from NASA and the Center for the Advancement of Science in Space (CASIS) will collect the research and hardware and distribute it to scientists and engineers for analysis.
