Ground controllers released the SpaceX Dragon cargo spacecraft from the International Space Station’s robotic arm at 4:58 a.m. EST. The capsule will begin a series of departure burns and maneuvers to move beyond the “keep out sphere” around the station for its return trip to Earth.
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 9:43 a.m. The capsule will splashdown about 10:36 a.m. in the Pacific Ocean, where recovery forces will retrieve the capsule and its nearly 4,100 pounds of cargo. This cargo will include science samples from human and animal research, external payloads, biology and biotechnology studies, physical science investigations and education activities.
The deorbit burn and splashdown will not be broadcast on NASA TV.
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, the only space station resupply spacecraft currently able to return to Earth intact, launched Dec. 15 on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station, and arrived at the station Dec. 17 for the company’s 13th NASA-contracted commercial resupply mission.

NASA TV will broadcast live the resupply ship’s departure starting Saturday at 4:30 a.m. Splashdown will not be televised.
Japanese astronaut Norishige Kanai worked a variety of life science experiments today exploring what happens to humans living in space. He started the morning drawing his blood samples and storing them in a science freezer for later analysis. He also stowed frozen science samples inside Dragon for return to Earth. At the end of the day, Kanai removed petri plates from a specialized microscope containing plant samples being observed for molecular and genetic changes caused by microgravity.
Students on Earth are remotely testing algorithms on a pair of internal satellites as part of a competition aboard the International Space Station today. Meanwhile, the Expedition 54 crew is packing up the SpaceX Dragon cargo craft for its Saturday departure and conducting biomedical operations.
Commander Alexander Misurkin and Flight Engineer Joe Acaba are monitoring tiny satellites known as SPHERES flying inside the Japanese Kibo laboratory module. Students on Earth have uploaded algorithms maneuvering the SPHERES to compete for creating the best designs relevant to future space missions.
NASA astronauts Mark Vande Hei and Scott Tingle are transferring rodents from the station’s animal habitat to a transporter aboard the Dragon resupply ship for return and analysis on Earth. The rodents were treated with a compound that fights muscle loss in microgravity and will be compared to a group of mice on Earth.
Japanese astronaut Norishige Kanai concluded a session of the Airways Monitoring experiment stowing the research gear in the U.S. Quest airlock. The study is analyzing exhaled air to maintain astronaut health on long-term space missions. Kanai also collected his biological samples for the Probiotics study looking at the immune system and intestinal microbes living inside space station crew members.
The Expedition 54 crew aboard the International Space Station is training for this weekend’s departure of the SpaceX Dragon commercial cargo craft. The crew is also exploring regenerative life support systems and how microgravity affects breathing.
This is the first time robotics controllers will command the release of Dragon from the ground while Acaba and Tingle monitor from the cupola as backups. NASA TV will broadcast live the resupply ship’s departure starting Saturday at 4:30 a.m. Splashdown off the coast of California is expected at 10:36 a.m. and will not be televised.
Experimental work also took place today on the orbital laboratory to help NASA learn how to support astronauts on longer missions farther out into space.
Acaba checked bacteria cultures that could be used for carbon dioxide removal and oxygen production supporting future regenerative life support systems. Japanese astronaut Norishige Kanai joined NASA astronaut Mark Vande Hei and measured their breathing rates today, specifically Nitric Oxide turnover in the lungs. Doctors want to minimize the risk of airway inflammation to keep astronauts healthier farther from Earth.
Robotics controllers are getting ready to uninstall the SpaceX Dragon cargo craft from the International Space Station on Friday before releasing it for a splashdown in the Pacific Ocean Saturday.

Tingle took a look at plant samples to observe their genetic and molecular responses to growing in space.
Commander Alexander Misurkin along with Acaba set up a pair of tiny internal satellites, also known as SPHERES, for a dry run today ahead of a competition. Students on Earth are competing to design the best algorithms that will operate the SPHERES to simulate future space operations such as dockings and flying formations.
Robotics controllers have completed the science cargo transfers from the rear of the SpaceX Dragon cargo ship, also known as its trunk. Dragon is due to depart the International Space Station Jan. 13 and return to Earth.
Over the holidays, the ground robotics teams remotely operated the Canadarm2 to remove a pair of new external experiments from Dragon and install them on the station. The teams also finished installing an older experiment back inside the cargo craft’s trunk in time for its departure.
Dragon delivered the Total and Spectral Solar Irradiance Sensor (TSIS-1) and the Space Debris Sensor (SDS) when it arrived on Dec. 17, 2017. TSIS-1 was attached to an External Logistics Carrier on the port solar alpha rotary joint. It will study the sun’s natural influence on the Earth’s ozone layer, atmospheric circulation, clouds, and ecosystems. The SDS was installed outside the Columbus lab module where it will directly measure the orbital debris environment around the space station for two to three years.
The successful RapidScat experiment was installed back in Dragon’s trunk after being delivered in September 23, 2014, on the SpaceX CRS-4 mission. RapidScat observed wind patterns on the ocean’s surface providing agencies better data for weather forecasting before ending its mission in August of 2016.
RapidScat will be destroyed inside Dragon’s trunk when it separates from the Dragon resupply ship to burn up over the Pacific Ocean. Dragon itself will safely parachute to a splashdown in the Pacific Ocean off the southern coast of California.
Filled with trash, the unpiloted ISS Progress 67 Russian cargo ship undocked from the aft port of the Zvezda Service Module of the International Space Station at 8:03 p.m. EST. Just after 11 p.m., Russian flight controllers will send commands to fire the Progress’ engines and deorbit the space freighter, sending it to a destructive entry over the unpopulated south Pacific Ocean.
The International Space Station’s three newest crew members are beginning their second week familiarizing themselves with the orbital lab’s operations and systems. They and the other three Expedition 54 crew mates are also busy today with cargo operations, space science and station maintenance.
Also, a Russian cargo craft is departing the station tonight after a six-and-a-half month stay docked to the Zvezda service module. The Progress 67 cargo craft will undock from Zvezda tonight at 8:03 p.m. EST then re-enter Earth’s atmosphere to burn up over the south Pacific Ocean.
Veteran cosmonaut Anton Shkaplerov and first-time astronauts Scott Tingle of NASA and Norishige Kanai of JAXA are in their second week in Earth orbit and getting used to life in space. The new space residents, who arrived Dec. 19, have time set aside in their schedules to adjust to life and work in weightlessness.
Two-time station resident Joe Acaba from NASA worked throughout Wednesday gathering items for stowage inside the SpaceX Dragon resupply ship. Kanai assisted Acaba with the pre-packing duties readying the cargo for return to Earth inside Dragon on Jan. 13.
Tingle strapped himself into an exercise bike this morning breathing into a tube for a study measuring physical exertion in microgravity. In this long-running experiment, doctors are researching ways to ensure astronauts stay fit and healthy in space to maintain mission success.
The SpaceX Dragon cargo spacecraft was installed on the Harmony module of the International Space Station at 8:26 a.m. EST.
The 13th contracted commercial resupply mission from SpaceX (CRS-13) delivered more than 4,800 pounds of supplies and payloads to the station. Among the research materials flying inside Dragon’s pressurized area, one investigation will demonstrate the benefits of manufacturing fiber optic filaments in a microgravity environment. Designed by the company Made in Space, and sponsored by the Center for the Advancement of Science in Space (CASIS), the investigation will attempt to pull fiber optic wire from ZBLAN, a heavy metal fluoride glass commonly used to make fiber optic glass. Results from this investigation could lead to the production of higher-quality fiber optic products for use in space and on Earth.
Dragon is scheduled to depart the station in January 2018 and return to Earth with more than 3,600 pounds of research, hardware and crew supplies.
