The Orbital ATK Cygnus cargo ship was bolted into place on the International Space Station’s Earth-facing port of the Unity module at 7:15 a.m. EST. The spacecraft will spend about three weeks attached to the space station before departing in early December. 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.
The spacecraft’s arrival brings close to 7,400 pounds of research and supplies to support Expedition 53 and 54. Highlights include:
The coli AntiMicrobial Satellite (EcAMSat) mission, which will investigate the effect of microgravity on the antibiotic resistance of E. coli, a bacterial pathogen responsible for urinary tract infection in humans and animals. Antibiotic resistance could pose a danger to astronauts, especially since microgravity has been shown to weaken human immune response. The experiment will expose two strains of E. coli to three different doses of antibiotics; one of these strains is deficient in the gene responsible for the increased antibiotic resistance in microgravity. Results from this investigation could help determine appropriate antibiotic dosages to protect astronaut health during long-duration missions and help us understand how antibiotic effectiveness may be increased in microgravity, as well as on Earth.
The Optical Communications and Sensor Demonstration (OCSD) project, which will study high-speed optical transmission of data and small spacecraft proximity operations. It will test functionality of laser-based communications using CubeSats that provide a compact version of the technology. Results from OCSD could lead to significantly enhanced communication speeds between space and Earth and a better understanding of laser communication between small satellites in low-Earth orbit.
The Biological Nitrogen Fixation in Microgravity via Rhizobium-Legume Symbiosis (Biological Nitrogen Fixation) investigation, which will examine how low-gravity conditions affect the nitrogen fixation process of Microclover, a resilient and drought tolerant legume. The nitrogen fixation process, a process by which nitrogen in the atmosphere is converted into a usable form for living organisms, is a crucial element of any ecosystem necessary for most types of plant growth. This investigation could provide information on the space viability of the legume’s ability to use and recycle nutrients and give researchers a better understanding of this plant’s potential uses on Earth.
The Integrated Solar Array and Reflectarray Antenna (ISARA), a hybrid solar power panel and communication solar antenna that can send and receive messages, will test the use of this technology in CubeSat-based environmental monitoring. ISARA may provide a solution for sending and receiving information to and from faraway destinations, both on Earth and in space.

The Cygnus resupply ship from Orbital ATK is less than 24 hours away from a rendezvous and capture at the International Space Station. Meanwhile, the Expedition 53 crew members are conducting human research and exploring growing crops in space.
Cygnus is in Earth orbit today conducting a series of orbital maneuvers refining its path to the space station Tuesday morning. Astronauts Paolo Nespoli and Randy Bresnik will be in the cupola early tomorrow waiting to capture Cygnus with the Canadarm2 at 4:50 a.m. EST. NASA TV will broadcast the capture and installation of Cygnus to the Unity module beginning at 3:15 a.m.
Bresnik and fellow NASA astronauts Mark Vande Hei and Joe Acaba also worked on some biomedical experiments today helping doctors understand how humans adapt to microgravity. Bresnik collected his blood and urine samples and stowed them in a science freezer for later analysis. Vande Hei and Acaba measured and recorded their body mass to observe bone and muscle impacts of living in space.
The launch of Orbital ATK’s Antares rocket carrying the Cygnus cargo spacecraft has scrubbed for Saturday after an aircraft was detected in the vicinity of the launch pad. The next launch attempt is set for Sunday, Nov. 12 at 7:14 a.m. EST.
The Expedition 53 crew is working out on a new exercise device today and testing new lights for their impact on health. Back on Earth, a new resupply rocket stands at its launch pad ready for a Saturday launch to the International Space Station.
Astronauts Joe Acaba and Mark Vande Hei worked out on the new Mini-Exercise Device-2 (MED-2) this morning performing dead lifts and rowing exercises. The duo tested its ability to provide reliable, effective workouts despite its smaller size to increase the habitability of a spacecraft.
Vande Hei is also analyzing the station’s new solid-state light-emitting diodes that are replacing older fluorescent lights. He conducted a series of tests throughout the day to determine how they impact crew sleep patterns and cognitive performance.
The Orbital ATK Cygnus cargo craft is encapsulated inside the Antares rocket and now stands vertical at the launch pad at Wallops Flight Facility in Virginia. Cygnus is due to launch Saturday at 7:37 a.m. EDT with about 7,400 pounds of new science experiments and fresh supplies for the Expedition 53 crew.
Cygnus will unfurl its cymbal-like UltraFlex solar arrays less than two hours after launch as it begins a two-day trip to the International Space Station. Astronaut Paolo Nespoli will command the Canadarm2 from the Cupola to grapple Cygnus when it arrives Monday morning at 5:40 a.m. Commander Randy Bresnik will back up Nespoli and monitor the approach and rendezvous.
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.
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.
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.
Three Expedition 53 astronauts conducted eye exams Tuesday morning two days ahead of a spacewalk. The crew is also preparing for a pair of upcoming commercial cargo missions.
Commander Randy Bresnik, who is leading all three spacewalks this month, joined his fellow spacewalkers for a periodic eye exam. Bresnik and Flight Engineers Mark Vande Hei and Joe Acaba scanned their eyes using an ultrasound device with guidance from doctors on the ground monitoring the crew’s health.
Paolo Nespoli, from the European Space Agency, did some rearranging inside the Japanese Kibo laboratory module today. He is preparing Kibo for new science gear arriving on a pair of private space freighters in November. Orbital ATK’s Cygnus resupply ship is due to launch mid-November and the SpaceX Dragon is planned to launch at the end of November.
Expedition 52 Flight Engineer Jack Fischer of NASA commanded the International Space Station’s Candadarm2 robotic arm to release the Cygnus spacecraft at 9:10 a.m. EDT while the space station was flying above the south Atlantic Ocean. Earlier, ground controllers detached Cygnus from the station and maneuvered it into place for its departure.
The spacecraft spent 44 days at the station after delivering approximately 7,600 pounds of supplies and science experiments to the orbiting laboratory and its Expedition 51 and 52 crew members for Orbital ATK’s seventh NASA-contracted commercial resupply mission.
Dubbed the “SS John Glenn” after the iconic Mercury and shuttle astronaut and U.S. Senator from Ohio, Cygnus will remain in orbit for a week in support of the SAFFIRE experiment and the deployment of four small Nanoracks satellites before Orbital ATK flight controllers send commands June 11 to deorbit the spacecraft for its reentry into the Earth’s atmosphere, where it will burn up over the Pacific Ocean. NASA TV will not provide a live broadcast of the Saffire experiment or the Cygnus deorbit burn and reentry, but imagery from Saffire will be posted on NASA.gov as it becomes available.
As Cygnus departs, the SpaceX Dragon spacecraft launched yesterday will close in on the station for its capture by Fischer and Whitson Monday, June 5. Using the Canadarm2 robotic arm, they will grapple the SpaceX cargo spacecraft at 10 a.m. NASA TV coverage will begin at 8:30 a.m.
