Activities on the International Space Station are moving ahead towards next week’s spacewalk to swap out thermal control equipment. Flight Engineers Ricky Arnold and Drew Feustel will work outside the orbital lab for the maintenance job on May 16.

Robotics engineers are setting up the worksite on the Port 6 truss today ahead of next week’s spacewalk. Ground teams are remotely maneuvering the Canadarm2 with the Dextre robotic hand attached to relocate a leaky pump flow control subassembly (PFCS). The Canadarm2 will then be positioned afterward to support Arnold’s and Feustel’s work next week.

The duo will work outside the station for about 6.5 hours to swap locations of 2 PFCS boxes. The PFCS controls the circulation of ammonia to keep station systems cool. Other spacewalk tasks planned in the timeline include swapping out a variety of communications gear.

The two spacewalkers gathered their tools and were joined on Tuesday by Flight Engineers Scott Tingle and Norishige Kanai for a spacewalk procedures review. The foursome also checked in with mission controllers to discuss the upcoming spacewalk. Tingle and Kanai will assist the spacewalkers in and out of their spacesuits next week and help choreograph the excursion.

Station Getting Ready for Spacewalks and Next Cargo Mission

Station Getting Ready for Spacewalks and Next Cargo Mission

International Space Station officials will preview a pair of upcoming spacewalks live on NASA TV Tuesday. Meanwhile, Orbital ATK is getting its Cygnus resupply ship ready for launch in less than two weeks while the Expedition 55 crew focuses on biomedical studies today.

Two NASA astronauts are going out for a spacewalk May 16 to swap out thermal control gear that circulates ammonia to keep station systems cool. Station experts will be on NASA TV beginning at 2 p.m. EDT Tuesday to preview next week’s spacewalk including a second spacewalk planned for June 14. Both excursions will be conducted by veteran spacewalkers Ricky Arnold and Drew Feustel.

Feustel and Arnold verified their spacesuits are sized correctly with assistance from astronauts Scott Tingle of NASA and Norishige Kanai from the Japan Aerospace Exploration Agency. Tingle also checked the batteries that power the U.S. spacesuits.

On May 20, just four days after the first spacewalk, Orbital ATK is planning to launch its Cygnus space freighter on a four day trip to the orbital laboratory. Cygnus will resupply the Expedition 55 crew with new science experiments, crew supplies, station hardware and gear that will be installed on the June 14 spacewalk.

Today’s science taking place onboard the station explored how microgravity affects blood pressure and blood vessels. Kanai started his day photographing his face to help scientists understand how the upward flow of fluids impacts intracranial pressure affecting a crew member’s eyes. He later attached sensors to his legs, scanned them with an ultrasound device and checked his blood pressure for the Vascular Echo study.

Following release from the International Space Station by ground controllers at 9:23 a.m. EDT, SpaceX’s Dragon cargo spacecraft splashed down in the Pacific Ocean at about 3 p.m. This marks the end of the company’s 14th contracted cargo resupply mission to the space station for NASA.

A boat will take the Dragon to the port at Long Beach, where some cargo will be removed and returned to NASA. Dragon will be prepared for a return journey to SpaceX’s test facility in McGregor, Texas, for processing.

Dragon is returning more than 4,000 pounds of NASA cargo and science samples from a variety of technological and biological studies about the space station. Some of the science returning on this flight includes samples from the Metabolic Tracking study that could lead to more effective, less expensive drugs, the APEX-06 investigation examining how to effectively grow crops in space, and the Fruit Fly Lab–03 investigation to research disease genes and immunity to help prepare for future long-duration human space exploration missions.

Dragon Heads Home After Month Long Stay at Station

Dragon Heads Home After Month Long Stay at Station

SpaceX Dragon departs the station
Cameras on the Canadarm2 robotic arm monitored the SpaceX Dragon resupply ship as it departed the space station Saturday morning.

Robotic flight controllers released the SpaceX Dragon cargo spacecraft from the International Space Station’s robotic arm at 9:23 a.m. EDT, and Expedition 55 Flight Engineer Scott Tingle of NASA is monitoring its departure.

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 2:06 p.m. The capsule will splashdown about 3 p.m. in the Pacific Ocean, where recovery forces will retrieve the capsule and its more than 4,000 pounds of cargo, including a variety of technological and biological studies.

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 is the only space station resupply spacecraft currently capable of returning cargo to Earth, and this was the second trip to the orbiting laboratory for this spacecraft, which completed its first mission nearly two years ago. SpaceX launched its 14th NASA-contracted commercial resupply mission to the station April 2 from Space Launch Complex 40 from Cape Canaveral Air Force Station in Florida on a Falcon 9 rocket that also previously launched its 12th NASA-contracted commercial resupply mission to the station.

Astronauts Assembling Gear for Installation During Upcoming Spacewalk

Astronauts Assembling Gear for Installation During Upcoming Spacewalk

The Expedition 55 crew members are getting their U.S. spacesuits and equipment ready for a spacewalk in two weeks. The Dragon cargo craft from SpaceX is nearly loaded with NASA science and gear ahead of its Saturday return to Earth.

NASA astronauts Ricky Arnold and Drew Feustel are assembling hardware today that will be installed on the International Space Station when they conduct a spacewalk on May 16. The duo were assisted throughout the day by fellow NASA astronaut Scott Tingle scrubbing U.S. spacesuit water cooling loops and testing water samples for conductivity.

The veteran spacewalkers were mating repaired components from an external television camera group (ETVCG) that will be attached to the starboard side of the Destiny laboratory module. Their primary spacewalking task however, will be the swap out of thermal control gear that circulates ammonia to keep station systems cool.

Final packing is taking place inside the Dragon space freighter today as Tingle loads critical time-sensitive research samples inside the Earth-bound resupply ship. Robotics controllers will detach Dragon from the Harmony module Friday before releasing it Saturday at 9:24 a.m. from the grips of the Canadarm2. NASA TV will begin its live broadcast of the departure at 9 a.m. but will not televise its 3 p.m. splashdown in the Pacific Ocean.
