The Expedition 56 crew members explored a variety of microgravity science today potentially improving the lives of people on Earth and astronauts in space. The orbital residents are also unpacking a new resupply ship and getting ready for the departure of another.
Cancer research is taking place aboard the International Space Station possibly leading to safer, more effective therapies. Flight Engineer Serena Auñón-Chancellor contributed to that research today by examining endothelial cells through a microscope for the AngieX Cancer Therapy study. AngieX is seeking a better model in space to test a treatment that targets tumor cells and blood vessels.
She also teamed up with Commander Drew Feustel imaging biological samples in a microscope for the Micro-11 fertility study. The experiment is researching whether successful reproduction is possible off the Earth.
The Northrop Grumman Cygnus space freighter has been packed full of trash and is due to leave the space station Sunday morning. Flight Engineer Alexander Gerst will command the Canadarm2 robotic arm to release Cygnus at 8:35 a.m. EDT as Auñón-Chancellor backs him up. It will orbit Earth until July 30 for engineering studies before burning up harmlessly over the Pacific Ocean.
Expedition 56 Commander Drew Feustel and Flight Engineer Ricky Arnold of NASA completed the sixth spacewalk at the International Space Station this year at 2:55 p.m. EDT, lasting 6 hours, 49 minutes. The two astronauts installed new high-definition cameras that will provide enhanced views during the final phase of approach and docking of the SpaceX Crew Dragon and Boeing Starliner commercial crew spacecraft that will soon begin launching from American soil.
They also swapped a camera assembly on the starboard truss of the station, closed an aperture door on an external environmental imaging experiment outside the Japanese Kibo module, and completed two additional tasks to relocate a grapple bar to aid future spacewalkers and secured some gear associated with a spare cooling unit housed on the station’s truss.
This was the 211th spacewalk in support of assembly and maintenance of the unique orbiting laboratory where humans have been living and working continuously for nearly 18 years. Spacewalkers have now spent a total of 54 days, 23 hours and 29 minutes working outside the station.
During the ninth spacewalk of Feustel’s career, he moved into third place for total cumulative time spent spacewalking with a total of 61 hours and 48 minutes. It was Arnold’s fifth spacewalk with a total time of 32 hours and 4 minutes.
NASA Television and the agency’s website have begun the broadcast of today’s spacewalk.
Expedition 56 Commander Drew Feustel and Flight Engineer Ricky Arnold of NASA are preparing to exit the International Space Station to make improvements and repairs to the orbiting laboratory. The spacewalk is scheduled to begin about 8:10 a.m. EDT and last about six-and-a-half hours.
Feustel and Arnold will install new high-definition cameras near an international docking adapter mated to the front end of the station’s Harmony module. The additions will provide enhanced views during the final phase of approach and docking of the SpaceX Crew Dragon and Boeing Starliner commercial crew spacecraft that will soon begin launching from American soil.
The astronauts also will swap out a camera assembly on the starboard truss of the station and close an aperture door on an external environmental imaging experiment outside the Japanese Kibo module.
Arnold and Feustel will begin Thursday’s spacewalk at 8:10 a.m. to install new high definition cameras to support upcoming commercial crew missions from SpaceX and Boeing to the orbital laboratory. The first uncrewed test missions are planned to begin later this year. The cameras will provide improved views of the commercial crew vehicles as they approach and dock to the station. NASA TV will provide complete live coverage of the 211th space station spacewalk starting at 6:30 a.m.
Auñón-Chancellor and Gerst, who just arrived at the station on Friday, will assist the spacewalkers on Thursday. Gerst will help the spacewalkers in and out of their spacesuits. Auñón-Chancellor will operate the Canadarm2 robotic arm. The duo practiced today on a computer the robotics procedures necessary to maneuver a spacewalker to and from the worksite on the starboard side of the station’s truss structure.
Arnold and Feustel had some extra time today to work on science and maintenance activities. Arnold worked with the Microgravity Science Glovebox to troubleshoot a semiconductor crystal growth experiment. Feustel performed some plumbing work in the Tranquility module before relocating a pair of incubator units to support new experiments being delivered on the next SpaceX Dragon cargo mission. Finally, the duo readied the Quest airlock and their spacesuits for Thursday morning’s spacewalk.
The Cygnus resupply ship from Orbital ATK is now open for business and the Expedition 55 crew has begun unloading the 7,400 pounds of cargo it delivered Thursday morning. The orbital residents are also conducting space research and preparing for a crew swap in early June.
There are now four spaceships parked at the International Space Station, the newest one having arrived to resupply the crew early Thursday morning. Astronauts Drew Feustel and Norishige Kanai opened Cygnus’ hatches shortly after it was installed to the Unity module. The cargo carrier will remain attached to the station until July so the astronauts can offload new supplies and repack Cygnus with trash.
NASA astronaut Scott Tingle, who caught Cygnus with the Canadarm2 robotic arm, swapped out gear inside a small life science research facility today called TangoLab-1. Tingle also joined Kanai later in the day transferring frozen biological samples from the Destiny lab module to the Kibo lab module.
The duo also joined Commander Anton Shkaplerov and continued to pack gear and check spacesuits ahead of their return to Earth on June 3 inside the Soyuz MS-07 spaceship. When the three crewmates land in Kazakhstan, about three and a half hours after undocking, the trio will have spent 168 days in space and conducted one spacewalk each.
Three new Expedition 56-57 crew members, waiting to replace the homebound station crew, are counting down to a June 6 launch to space. Astronauts Serena Auñón-Chancellor and Alexander Gerst will take a two-day ride to the space station with cosmonaut Sergey Prokopyev inside the Soyuz MS-09 spacecraft for a six-month mission aboard the orbital laboratory.
The Orbital ATK Cygnus cargo ship was bolted into place on the International Space Station’s Earth-facing port of the Unity module at 8:13 a.m. EDT. The spacecraft will spend about seven weeks attached to the space station before departing in July. After it leaves the station, the uncrewed spacecraft will deploy several CubeSats before its fiery re-entry into Earth’s atmosphere as it disposes of several tons of trash.
Orbital ATK’s Cygnus was launched on the company’s Antares rocket Monday, May 21, from the Mid-Atlantic Regional Spaceport Pad 0A at NASA’s Wallops Flight Facility in Virginia. The spacecraft’s arrival brings about 7,400 pounds of research and supplies to support Expedition 55 and 56. Highlights include:
The Ice Cubes Facility, the first commercial European opportunity to conduct research in space, made possible through an agreement with ESA (European Space Agency) and Space Applications Services.
The Microgravity Investigation of Cement Solidification (MICS) experiment is to investigate and understand the complex process of cement solidification in microgravity with the intent of improving Earth-based cement and concrete processing and as the first steps toward making and using concrete on extraterrestrial bodies.
Three Earth science CubeSats
RainCube (Radar in a CubeSat) will be NASA’s first active sensing instrument on a CubeSat that could enable future rainfall profiling missions on low-cost, quick-turnaround platforms.
TEMPEST-D (Temporal Experiment for Storms and Tropical Systems Demonstration) is mission to validate technology that could improve our understanding of cloud processes.
CubeRRT (CubeSat Radiometer Radio Frequency Interference Technology) will seek to demonstrate a new technology that can identify and filter radio frequency interference, which is a growing problem that negatively affects the data quality collected by radiometers, instruments used in space for critical weather data and climate studies.

The Cygnus space freighter from Orbital ATK is closing in on the International Space Station ready to deliver 7,400 pounds of cargo Thursday morning. The Expedition 55 crew members are getting ready for Cygnus’ arrival while also helping researchers understand what living in space does to the human body.
NASA TV is set to begin its live coverage of Cygnus’ arrival at the orbital lab Thursday at 3:45 a.m. EDT. Flight Engineer Scott Tingle will be inside the Cupola and command the Canadarm2 robotic arm to reach out and capture Cygnus at 5:20 a.m. Robotics engineers at Mission Control will then take over and remotely install Cygnus to the Earth-facing port of the Unity module later Thursday morning.
The crew started its day collecting blood and urine samples for a pair of experiments, Biochemical Profile and Repository, looking at the physiological changes taking place in astronauts. Those samples are stowed in science freezers for return to Earth so scientists can later analyze the proteins and chemicals for indicators of crew health.
Another pair of experiments taking place today is looking at bone marrow, blood cells and the cardiovascular system. The Marrow study, which looks at white and red blood cells in bone marrow, may benefit astronaut health as well as people on Earth with reduced mobility or aging conditions. The Vascular Echo experiment is observing stiffening arteries in astronauts that resembles accelerated aging.
Two Expedition 55 Flight Engineers are using virtual reality and computer training today to prepare for next week’s spacewalk at the International Space Station. Robotics controllers from Houston and Japan are also maneuvering a pair of robotic arms for the upcoming spacewalk and satellite deployments.
NASA astronauts Ricky Arnold and Drew Feustel will conduct the 210th spacewalk at the space station beginning Wednesday, May 16 at 8:10 a.m. EDT. The veteran spacewalkers will work for about 6.5 hours swapping thermal control gear that controls the circulation of ammonia to keep external station systems cool. NASA TV begins its live coverage at 6:30 a.m.
The veteran spacewalkers checked the functionality a pair of jet packs that will be attached to their U.S. spacesuits next week. The jet packs, known as Simplified Aid For EVA Rescue (SAFER), provide mobility for spacewalkers in the unlikely event they become untethered from the station. The duo also wore virtual reality goggles to practice maneuvering their SAFER jet packs and reviewed their spacewalk procedures.
Robotics controllers from opposite sides of the world maneuvered a pair of robotic arms independently of each other today. Canada’s 57.7-foot-long robotic arm, nicknamed Canadarm2, was remotely positioned today by engineers in Houston in advance of next week’s spacewalk activities. Controllers from the Japan Aerospace Exploration Agency remotely operated the Kibo laboratory module’s robotic arm to prepare for the deployment of small satellites Friday morning.
Robotics controllers and Expedition 55 crew members are getting ready for the departure of the SpaceX Dragon resupply ship next week. The commercial space freighter will leave the International Space Station and splashdown in the Pacific Ocean on Wednesday loaded with cargo for retrieval and analysis.
Flight Engineer Ricky Arnold powered up command and communications gear today that will aid the crew when Dragon departs the station on Wednesday at 10:22 a.m. EDT. NASA TV will begin its live coverage of the departure activities at 10 a.m. Dragon will splashdown in the Pacific Ocean about six hours later to be recovered by SpaceX and NASA personnel. The splashdown off the southern coast of California will not be seen on NASA TV.
The Canadarm2 will be remotely maneuvered today to grapple Dragon today while it is still attached to the Harmony module. In the meantime the 57.7-foot-long robotic arm and its fine-tuned robotic hand, also known as Dextre, are completing the installation of an external materials exposure experiment outside of Japan’s Kibo laboratory module.
Astronauts Drew Feustel and Scott Tingle are still packing Dragon today with a variety of cargo including space station hardware and research samples. The STaARS-1 experiment facility has completed a year of operations at the station and is being readied for its return aboard Dragon next week. The research device supported observations of living systems exposed to simulated gravity such as Earth, the Moon and Mars. Feustel also stowed faulty life support gear in Dragon for refurbishment back on Earth.
Among the research arriving to the U.S. National Laboratory is a Metabolic Tracking investigation to evaluate the use of a new method to test, in microgravity, the metabolic impacts of pharmaceutical drugs. This could lead to more effective, less expensive medicines on Earth. The Multi-use Variable-g Platform (MVP) will serve as a new test bed aboard the space station, able to host 12 separate experiment modules with samples such as plants, cells, protein crystals and fruit flies. The Center for the Advancement of Science in Space (CASIS), which manages the U.S. National Laboratory, is sponsoring the investigation and the MVP.
Dragon will remain attached to the space station until May, when it will return to Earth with more than 3,500 pounds of research, hardware and crew supplies.
