NASA Television will provide live coverage of the departure of Orbital ATK’s Cygnus cargo spacecraft from the International Space Station beginning at 9 a.m. EDT on Tuesday, June 14. Release from the space station’s Canadarm2 is scheduled for 9:30 a.m.
About five hours after departure, the Saffire-I experiment will take place onboard the uncrewed cargo craft. Saffire-I provides a new way to study a realistic fire on a spacecraft. This hasn’t been possible in the past because the risks for performing such studies on crewed spacecraft are too high. Instruments on the returning Cygnus will measure flame growth, oxygen use and more. Results could determine microgravity flammability limits for several spacecraft materials, help to validate NASA’s material selection criteria, and help scientists understand how microgravity and limited oxygen affect flame size. The investigation is crucial for the safety of current and future space missions.

Surface and air samples were taken today inside the International Space Station to study the diversity of microbes on the orbital lab. Hardware was also set up to download imagery taken for the Strata-1 study which is exploring how soil from other planetary bodies might behave. That research may help scientists design future spacesuits and space gear.
SpaceX is getting ready for the release and splashdown of its Dragon cargo craft on May 11. The 57.7-foot Canadarm2 robotic arm is inspecting Dragon’s thermal protection system and will grapple the spacecraft later today.
The astronauts onboard the International Space Station are researching how microgravity affects fluid shifts in a crew member’s body. Ground controllers are also guiding Canada’s robotic arm into position before next week’s grapple and release of the SpaceX Dragon spacecraft.
The Fluid Shifts experiment will wrap up operations this week with the crew wearing specialized body suits. The suits, known as Chibis Lower Body Negative Pressure devices, measure how fluids move from the lower body to the upper body while living in space. The research also observes fluid shifts in and out of cells and blood vessels which may impact head pressure potentially affecting vision.
Robotics controllers are remotely guiding the Canadarm2 to the Harmony module where it will grapple Dragon ahead of the spacecraft’s May 11 release and splashdown in the Pacific Ocean. Yesterday, the controllers surveyed the Alpha Magnetic Spectrometer’s condition with the Canadarm2 and its cameras.
Cosmonaut Oleg Skripochka is on his second mission aboard the space station. His first mission during Expedition 25/26 lasted 159 days. Currently, he is Expedition 47 Flight Engineer and today is his 47th day aboard the orbital lab since his March arrival with fellow crew members Jeff Williams and Alexey Ovchinin.
Today, the crew is observing how the lack of gravity affects plants and rodents. NASA is using the observations to improve the health of astronauts in space and humans on Earth.
The crew is stowing plant samples harvested for the Plant Gravity Sensing botany study to understand how roots sense gravity. The samples are being inserted into a science freezer for return to Earth aboard the SpaceX Dragon next week. Results may help astronauts grow their own food while living in space.
Rodents are also being observed in a habitat designed to house them in space. The Rodent Research-3 experiment is studying how space changes the musculoskeletal system and if an antibody that prevents muscle weakening on Earth works in space.
Dragon is still being loaded with gear and science for analysis on the ground. The private space freighter will be removed from the Harmony module and released from the Canadarm2 robotic arm for a splashdown in the Pacific Ocean May 11.
The International Space Station crew is wrapping up the week after working on a series of ongoing life science and robotics studies. The SpaceX Dragon is also nearing the end of its stay and preparing for a return to Earth.
The astronauts have been helping scientists gather data on what happens to the human body when exposed to microgravity to help NASA plan longer missions farther out into space. Observations from the human research studies help doctors design exercise techniques, diets and other countermeasures to keep astronauts healthy.
British astronaut Tim Peake collected tap water and body samples for the Energy experiment today. That study is aiding doctors’ efforts to determine an astronaut’s energy requirements to improve crew health and performance. He also tested the ability of controlling a rover on Earth, or any planetary surface, from a computer on a spacecraft. The METERON experiment may benefit future missions to Mars or hazardous tasks on Earth.
Experiment samples, gear and other hardware is being packed inside the Dragon space freighter attached to the Harmony module. Dragon will be released from Harmony May 11 ending a month-long stay. After its departure it will splashdown in the Pacific Ocean a few hours later where the spacecraft and its cargo will be retrieved by SpaceX engineers.
