Dragon Cargo Spacecraft Leaves Station Packed With Science
Dec. 16, 2024: International Space Station Configuration. Five spaceships are parked at the space station including the SpaceX Dragon Freedom, the Northrop Grumman Cygnus resupply ship, the Soyuz MS-26 crew ship, and the Progress 89 and 90 resupply ships.
At 11:05 a.m. EST, the unpiloted SpaceX Dragon spacecraft undocked from the forward port of the Harmony module at the International Space Station following a command from ground controllers at SpaceX.
After re-entering Earth’s atmosphere, the spacecraft will make a parachute-assisted splashdown off the coast of Florida on Tuesday, Dec. 17. NASA will not stream the splashdown but will post updates on the agency’s space station blog.
Filled with nearly 6,000 pounds of crew supplies, science investigations, and equipment, the spacecraft arrived to the orbiting laboratory Nov. 5 after it launched Nov. 4 on a Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida for the agency’s SpaceX 31st commercial resupply services mission.

NASA, SpaceX Adjust Dragon Undock Date Due to Weather
International Space Station Configuration. Six spaceships are parked at the space station including the SpaceX Dragon Freedom, the SpaceX Dragon cargo spacecraft, the Northrop Grumman Cygnus resupply ship, the Soyuz MS-26 crew ship, and the Progress 89 and 90 resupply ships.
Mission managers waved off the planned return of a Dragon resupply spacecraft on Sunday, Dec. 15, due to forecasted unfavorable weather conditions at the splashdown sites off the coast of Florida. NASA and SpaceX now are targeting no earlier than Monday, Dec. 16, for the next undocking opportunity of NASA’s SpaceX 31st commercial resupply services spacecraft.
Crew Studies Physics and Biology, Preps for Spacewalk, Dragon Undocking Adjusted
An orbital sunrise crowns Earth’s horizon in this photograph from the International Space Station as it orbited 261 miles above Brazil.
A space exposure experiment, a micro-algae study, and eye exams topped the research schedule for the Expedition 72 crew members at the end of the week. The orbital residents also continue to gear up for a spacewalk planned for next week at the International Space Station.
NASA astronaut and station Commander Suni Williams spent most of her day inside the Tranquility module working on the Nanoracks Bishop airlock. She was joined at the beginning of her shift by NASA Flight Engineer Butch Wilmore who helped her prepare the Euro Materials Aging (EMA) experiment for installation inside Bishop. Afterward, she inspected one portion of the EMA study that will observe organic molecules and how they adapt to the external space environment.
NASA Flight Engineer Don Pettit looked at another segment of the EMA hardware that will expose a variety of materials to outer space to monitor how they age over time. Finally, NASA Flight Engineer Nick Hague inspected the Bishop airlock with the EMA experiment inside, closed its hatch, and prepared the airlock for its upcoming depressurization.
On Monday, the Canadarm2 robotic arm will detach Bishop with the EMA inside from Tranquility and maneuver it toward the Columbus laboratory module. Next, the EMA will be robotically installed on the Bartolomeo research platform attached to the outside of Columbus. The external investigation will operate outside Columbus for about a year.
Hague at the beginning of his shift on Friday, swapped samples of micro-algae inside the BioLab incubator located in Columbus. Researchers are exploring the potential of micro-algae as a way to remove carbon dioxide, produce oxygen, and grow food on spacecraft. At the end of the day, Williams partnered with Pettit and Wilmore for eye exams using standard medical imaging hardware found in a doctor’s office on Earth. The trio were joined by ground doctors monitoring in real-time who want to understand how living in weightlessness affects vision and the human eye.
Two cosmonauts continue their preparations for a spacewalk on Thursday, Dec. 19, to remove external science experiments and relocate European robotic arm hardware. Roscosmos Flight Engineers Alexey Ovchinin and Ivan Vagner began Friday installing components on their Orlan spacesuits. Next, the duo pedaled on an exercise bicycle for a pre-spacewalk fitness assessment. Finally, the cosmonauts wrapped up the day’s suit work installing lights, batteries, and video cameras they will wear on their spacesuits during the planned six-hour and 40-minute spacewalk next week.
Roscosmos Flight Engineer Aleksandr Gorbunov trained to use the European robotic arm reviewing the laptop computers that support the robotic arm attached to the Nauka science module. Following that work, the first-time space flyer swapped out life support hardware then installed Earth observation gear to view the effects of natural and human-caused catastrophes in different wavelengths.

NASA and SpaceX now are targeting no earlier than Sunday, Dec. 15, for the next undocking opportunity of NASA’s SpaceX 31st commercial resupply services spacecraft.
Crew Packs Science for Exposure, Studies Immune System, and Preps for Spacewalk
A vivid aurora streams over the Earth as the space station orbited 273 miles above the southern Indian Ocean in between Australia and Antarctica.
The Expedition 72 crew prepared a science experiment for placement outside the International Space Station and studied space-caused cellular stress and tissue damage on Thursday. Spacewalk preparations are also ongoing to remove and relocate hardware on the orbital outpost next week.
EMA will expose a variety of materials to the space environment to learn how to improve the development of space hardware and applications for missions to the Moon, Mars, and beyond. The external investigation will operate outside Columbus for about a year.
NASA Flight Engineer Nick Hague continued his cellular immunity research processing blood samples in the Harmony module. He removed the samples from the Kubik research incubator after overnight stowage and spun them inside the Human Research Facility’s centrifuge. Afterward, Hague stowed the blood specimens inside a science freezer then powered down and uninstalled Kubik. Doctors on the ground will analyze the samples to understand the effects of living in space on the human immune system.
All four NASA astronauts relaxed and took a half-a-day off at the end of their shifts on Thursday. The quartet will have a busy day on Friday as they prepare the Bishop airlock and the Euro Materials Aging experiment for their robotic move next week.
Roscosmos Flight Engineers Alexey Ovchinin and Ivan Vagner continued their preparations for a spacewalk planned to begin at 10:10 a.m. EST on Thursday, Dec. 19, for science and robotics hardware transfers. The cosmonauts wore their pressurized Orlan spacesuits and practiced maneuvering to the Poisk airlock where they will exit into the vacuum of space. Fellow cosmonaut and flight engineer Aleksandr Gorbunov joined the duo afterward and reviewed procedures to depressurize and repressurize the airlock when the spacewalkers exit and enter the station.
Ovchinin and Vagner also had time for a cardiac study wearing electrodes and arm cuffs measuring their heart activity and blood pressure. Gorbunov focused on orbital plumbing tasks before the spacewalk reviews. At the end of his shift, he joined his cosmonaut crewmates for a test to learn how international crews and mission controllers from around the world can communicate better.
