NASA and SpaceX Collaboration

NASA, in collaboration with its international partners, is gearing up to receive a wealth of scientific research samples and essential hardware as a SpaceX Dragon spacecraft prepares to leave the International Space Station (ISS) on Thursday, December 5. The live coverage of this significant undocking event will begin at 10:50 a.m. EST on NASA+, providing an inside look at this momentous occasion.

Dragon's Departure Schedule

The Dragon spacecraft is scheduled to undock from the forward port of the ISS's Harmony module at 11:05 a.m. Following this, it will fire its thrusters to ensure a safe distance from the station, marking the successful completion of another vital cargo mission.

Re-Entry and Splashdown

After re-entering Earth's atmosphere, the Dragon will make a splashdown off the coast of Florida, although NASA has announced that it will not live-stream the splashdown. Instead, updates will be posted on the agency's space station blog to keep the public informed.

Cargo Contents of the Dragon

This Dragon spacecraft is transporting nearly 6,000 pounds of crew supplies, scientific investigations, and equipment back to Earth. It previously arrived at the ISS on November 5, having launched on November 4 from NASA's Kennedy Space Center aboard a Falcon 9 rocket as part of SpaceX's 31st commercial resupply mission.

Significant Scientific Experiments

Among the treasures returning home are significant scientific equipment and samples that took advantage of the unique microgravity environment of the ISS. Noteworthy items include GISMOS (Genes in Space Molecular Operations and Sequencing), which successfully sequenced microbial DNA from the station's water system—providing unprecedented insights into the microbial population present.

SpaceTED Experiment

Another crucial experiment returning is SpaceTED (Space Tissue Equivalent Dosimeter), which has been operational for 11 months. It gathered essential data concerning crew radiation exposure while characterizing the space radiation environment—a remarkable achievement extending its operational life beyond the original six-month mission plan.

European Space Agency's 3D Printing

The Dragon will also carry home specimens printed with the European Space Agency’s (ESA) Metal 3D Printer, intended for further study and comparison with Earth-printed counterparts. This experiment highlights the potential for manufacturing technologies in the microgravity environment, with the goal of understanding performance and limitations during crewed missions.

International Space Art and Poetry Contest

In a remarkable blend of science and creativity, the International Space Art and Poetry Contest winners' submissions, ranging from drawings to poems, will also be returning to Earth. These pieces were printed in space, photographed from the cupola, and will now be reunited with their young creators.

Plasmonic Bubbles Experiment

Additionally, researchers involved with the Plasmonic Bubbles experiment will analyze high-speed video of bubble behavior in microgravity to enhance their understanding of molecular deposition. These findings could lead to advancements in detection methods for healthcare and environmental applications.

ISS Contributions to Science

For over two decades, the ISS has been at the forefront of scientific research, enabling discoveries that are impossible to achieve on Earth. As NASA shifts its focus toward ambitious deep-space missions—such as the Artemis campaign aimed at returning humans to the Moon and preparing for future explorations to Mars—the contributions from the ISS remain indispensable for understanding long-duration spaceflight challenges and fostering commercial opportunities in low Earth orbit.
