Two astronauts are training for Monday’s planned arrival of Orbital ATK’s newest Cygnus cargo craft dubbed the S.S. Eugene Cernan. The crew is also analyzing the International Space Station’s atmosphere and studying how crew performance adapts to microgravity.
Orbital ATK is counting down to a Veteran’s Day launch of its Cygnus spacecraft atop an Antares rocket from Wallops Flight Facility in Virginia. The rocket is scheduled to blast off Saturday at 7:37 a.m. EST with about 7,400 pounds of science gear and crew supplies packed inside Cygnus.
Commander Randy Bresnik and Flight Engineer Paolo Nespoli are training today to capture Cygnus with the Canadarm2 robotic arm. Nespoli will command the Canadarm2 to grapple Cygnus at 5:40 a.m. Monday when it reaches a point about 10 meters from the station. Bresnik will back up Nespoli and monitor the spacecraft’s approach and rendezvous.
Astronaut Mark Vande Hei has been helping doctors this week understand the risk of living inside the closed environment of a spacecraft for the Airway Monitoring study. He set up gear to analyze the air in the space station for dust and gases that could inflame an astronaut’s respiratory system. Results will help doctors improve crew health as NASA plans human missions farther and longer into space.
Nespoli started his day studying how floating in space impacts interacting with touch-based technologies and other sensitive equipment. Observations from the Fine Motor Skills study may influence the design of future spaceships and space habitats.
The Expedition 53 crew explored ways to protect astronauts from space radiation as well as dust particles floating inside a spacecraft. The residents of the International Space Station also worked on cosmic ray gear, a U.S. spacesuit and audio equipment.
European Space Agency astronaut Paolo Nespoli tested a personal radiation shielding garment today. Water, used for its shielding properties, is placed in garment containers that cover organs that are especially sensitive to cosmic radiation.
NASA astronaut Mark Vande Hei studied how gases and dust in the station’s atmosphere impact breathing aboard a spacecraft. He set up ultra-sensitive monitors that analyze exhaled air to detect crew health impacts. Results will help doctors and engineers improve conditions for future astronauts traveling longer and farther into space.
NASA astronaut Joe Acaba worked on a U.S. spacesuit’s water system before changing out a hard drive and installing new software on a support laptop for the Alpha Magnetic Spectrometer cosmic ray detector. Commander Randy Bresnik replaced faulty electronics gear inside the Harmony module restoring power to an internal audio speaker unit.
Orbital ATK’s eighth commercial cargo mission is set to launch to the International Space Station at 7:37 a.m. EST Veteran’s Day on Nov. 11. The Antares rocket carrying the Cygnus cargo craft will blast off from Wallops Flight Facility, Virginia, with over 7,000 pounds of food, supplies and research gear.
NASA astronaut Mark Vande Hei collected and stowed saliva samples today that will be analyzed later for a study on the human immune system and metabolism. Bresnik took panoramic photographs inside the Kibo laboratory module to prepare for the upcoming Astrobee experiment. Astrobee consists of three free-flying, cube-shaped robots that will be tested for their ability to assist astronauts and ground controllers.
When you’re on top of the world—or orbiting it—there’s no better place to be. NASA astronauts aboard the International Space Station (ISS) had a late night yesterday, staying up to watch a special uplink from Mission Control: Game 7 of the World Series. The winning outcome was cause for celebration, as the Astros have many fans at NASA’s Johnson Space Center in Houston, which is home base for the astronauts.
Today, the crew worked to size up the exercise equipment they rely on to sustain muscle mass and prevent bone loss while living and working in space. They set up cameras in Node 3 to capture video from multiple angles of the Advanced Resistive Exercise Device (ARED) and Miniature Exercise Device (MED-2) hardware, applied body markers, performed exercises and transferred the video for delivery to Mission Control. Aboard ISS, the exercise equipment is large and bulky, which is OK because the orbiting laboratory is about the size of a three-bedroom house. But, for Mars or other destinations beyond low-Earth orbit, available space will be difficult to come by. MED-2 aims to demonstrate that small robotic actuators can provide the same quality motion and resistance for crew workout sessions, thus reducing the size and weight of exercise devices for space missions farther out and lengthier in duration. Evaluating MED-2’s game-changing technology is crucial to the design and development of second- and third-generation hardware that is much lighter, smaller and more reliable than what is used now.
An Expedition 53 crew member read “Notable Notebooks Scientists and Their Writings Read” on camera for Story Time from Space. These recordings are downlinked and then used in schools, combining science literacy with simple concept experiments that children can follow along with on the ground. The videos are posted in a library with accompanying educational materials, further promoting science, technology, engineering and math to budding scientists, engineers and explorers.
The station’s altitude was raised last night during a three minute, 26-second firing of the ISS Progress 67 thrusters. The reboost of the complex was the first of two such maneuvers this month to set up the correct trajectory for the landing of the Expedition 53 crew on Dec. 14 in south central Kazakhstan and the launch, three days later, of the Expedition 54-55 crew from the Baikonur Cosmodrome in Kazakhstan.
Routine—and not-so-routine—housekeeping duties continue for Expedition 53 aboard the International Space Station in preparation for an upcoming Orbital ATK 8 (OA-8) commercial launch targeted for Nov. 11.
The crewmates prepared the Permanent Multipurpose Module rack fronts to accept cargo by moving smaller items off and staging them for disposal. During OA-8 cargo operations, the items marked for disposal will be swapped with new cargo arriving aboard OA-8.
During Orbital ATK’s eighth Cygnus resupply mission, the cargo craft will make a nine-minute ascent to space and then begin a two-day trek to the space station. Upon arrival, it will captured by Canadarm2 and installed for a month-long stay. Tonight, ground teams will reboost the station using the thrusters on Progress 67, which will put it at the proper altitude to meet up with Cygnus.
The crew also spent part of the workday photo documenting their uncommon “home life” aboard the orbiting laboratory for the Canadian Space Agency study called At Home in Space. This investigation assesses the culture, values and psychosocial adaptation of astronauts to a space environment shared by multinational crews during long mission timeframes. Questionnaires answered by the crew will help answer if astronauts develop a unique, shared space culture as an adaptive strategy for handling the cultural differences they encounter in their isolated and confined environment by creating a home in space.
For Flight Engineers Mark Vande Hei and Joe Acaba of NASA, their day was punctuated by an educational downlink with students from Shaker Heights High School in Cleveland, Ohio. The students were immersed in the science and technology studies being executed daily approximately 240 miles above Earth.
The Expedition 53 crew capped off last week’s investigations with fresh pickings of lettuce, cabbage and mizuna harvested from the Veg-03 investigation. There’s still some left, though, for the remainder of the vegetation will be allowed to grow and sprout new leaves. Since future long-duration explorers will expected to grow their own food to survive the harsh environment of space and Mars, understanding how plants respond to microgravity is an important component to a robust astronaut food system.
Plants are still on the table for the crew, so to speak, as the week kicks off. Following last week’s successful assembly and installation of the Advanced Plant Plant Habitat facility into the EXpedite the PRocessing of Experiments to Space Station (EXPRESS) Rack 5 (ER5), today the crew moved the Space Acceleration Measurement System (SAMS) Sensor Enclosure to ER5. The automated plant habitat facility will be used to conduct plant bioscience research aboard the International Space Station by providing a large, enclosed, environmentally controlled chamber.
The crewmates also set up the payload components for EarthKAM in Node 2 for a weeklong imaging session. Sally Ride EarthKAM allows thousands of students worldwide to photograph and examine Earth from a space crew’s perspective. Using the Internet, the students control a special digital camera mounted on the space station to photograph coastlines, mountain ranges and other geographic items of interest from the incomparable viewpoint of space. Later, the varied topographies are shared online for the public and participating classrooms to observe.
Around noon EDT, Station Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA shared insights about living and working aboard the nation’s most unique U.S. National Laboratory with students from Santa Monica High School in Santa Monica, California.
Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA completed a 6 hour, 49 minute spacewalk at 2:36 p.m. EDT. The two astronauts installed a new camera system on the Canadarm2 robotic arm’s latching end effector, an HD camera on the starboard truss of the station and replaced a fuse on the Dextre robotic arm extension.
The duo worked quickly and were able to complete several “get ahead” tasks. Acaba greased the new end effector on the robotic arm. Bresnik installed a new radiator grapple bar. Bresnik completed prep work for one of two spare pump modules on separate stowage platforms to enable easier access for potential robotic replacement tasks in the future. He nearly finished prep work on the second, but that work will be completed by future spacewalkers.
This was the fifth spacewalk of Bresnik’s career (32 hours total spacewalking) and the third for Acaba (19 hours and 46 minutes total spacewalking). Space station crew members have conducted 205 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 53 days, 6 hours and 25 minutes working outside the station.
Two NASA astronauts switched their spacesuits to battery power this morning at 7:47 a.m. EDT aboard the International Space Station to begin a spacewalk planned to last about 6.5 hours. Live coverage is available on NASA Television and the agency’s website.
Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA will replace a camera light assembly on the Canadarm2 latching end effectors (LEE) that spacewalkers installed on the Canadarm2 robotic Oct. 5. They will also install an HD camera outside the station among other tasks in the 205th spacewalk in support of assembly and maintenance in station history.
Bresnik is wearing the suit with red stripes, and helmet camera #18. Acaba is wearing the suit with no stripes, and helmet camera #17.

Four Expedition 53 crewmates huddled together and made final preparations the day before the third and final spacewalk planned for October. Meanwhile, NASA’s commercial partner Orbital ATK has announced Nov. 11 as the new launch date for its Cygnus cargo carrier to the International Space Station.
Commander Randy Bresnik and Flight Engineer Joe Acaba are reviewing procedures and configuring tools before their spacewalk set for Friday at 8:05 a.m. EDT. NASA astronaut Mark Vande Hei and Paolo Nespoli from the European Space Agency will assist the spacewalkers in and out of their spacesuits and guide the duo as they work outside.
The spacewalk was originally set for Wednesday before mission managers replanned a new set of tasks due to a camera light failure. Bresnik and Acaba will now replace the camera light assembly on the Canadarm2’s newly installed Latching End Effector and install an HD camera on the starboard truss. The duo will also replace a fuse on Dextre’s payload platform and remove thermal insulation on two electrical spare parts housed on stowage platforms.
Orbital ATK is targeting the launch of its eighth Cygnus resupply mission to the station for Nov. 11. Cygnus will make a nine-minute ascent to space after launch, then begin a two-day trek to the station where it will be installed for a month-long stay after its capture by the Canadarm2.
The Expedition 53 crew trained for a medical emergency in space today after spending the morning on weekly housecleaning tasks. Afterward, two astronauts reviewed procedures and checked their tools ahead of Friday’s spacewalk.
Cosmonaut Alexander Misurkin joined NASA astronauts Mark Vande Hei and Joe Acaba for a routine training session to handle a medical emergency aboard the International Space Station. The trio reviewed medical hardware, chest compression techniques and individual roles and responsibilities.
Afterward, Acaba moved on to spacewalk preparations with Commander Randy Bresnik. The spacewalkers are due to begin a 6.5 hour spacewalk Friday at 8:05 a.m. EDT. NASA TV will cover the spacewalking activities live beginning at 6:30 a.m.
This will be the third spacewalk this month and consists of repackaged tasks that include the replacement of a camera assembly on the newly installed Latching End Effector, the installation of an HD camera on the starboard truss, the replacement of a fuse on Dextre’s payload platform and the removal of thermal insulation on two electrical spare parts housed on stowage platforms.
