A U.S. cargo craft packed with 8,200 pounds of science and supplies is orbiting Earth today heading toward the International Space Station for a Tuesday morning cargo delivery. Meanwhile, the orbital residents started the work week with their normal complement of microgravity research and standard lab maintenance tasks.

Northrop Grumman’s Cygnus space freighter lifted off atop a Space Falcon 9 rocket at 11:02 a.m. EDT on Sunday from Florida. The cargo craft is loaded with a range of new experiments to investigate liquid and gas flows, centripetal force, DNA repair mechanisms, cellular expansion, and more. The weightless environment of the orbital outpost allows investigators to explore phenomena and gain insights not possible in Earth’s gravity conditions.

NASA astronauts Matthew Dominick and Jeanette Epps will be on duty Tuesday morning as Cygnus nears the space station during its automated approach and rendezvous. Dominick will be at the controls of the robotics workstation ready to command the Canadarm2 robotic arm to reach out and grapple Cygnus. Epps will be at Dominick’s side backing him up as the spacecraft completes its slow and methodical space delivery. The two Cygnus teammates had a light-duty day on Monday and went to bed early to get a fresh start and prepare for the spacecraft’s early arrival. After Cygnus is captured, robotics controllers on the ground will take over and remotely command the Canadarm2 and guide Cygnus to a berthing on the Unity module’s Earth-facing port.

The Cygnus spacecraft has completed two delta velocity burns, and it remains on track for a capture by the space station’s robotic arm slated for 3:10 a.m. on Tuesday, Aug. 6. The Cygnus spacecraft is in a safe trajectory, and all other systems are operating normally.

Shortly after launch on Sunday, the spacecraft performed as designed by cancelling a scheduled engine burn due to a slightly low initial pressure reading flagged by the Cygnus onboard detection system. Engineers at Northrop Grumman’s mission control center in Dulles, Virginia evaluated the pressure reading, confirmed it was acceptable and re-worked the burn plan to arrive at the space station on the originally planned schedule.

NASA will provide live coverage of the spacecraft’s arrival beginning at 1:30 a.m. Aug. 6 on NASA+, NASA Television, the NASA appYouTubeXFacebook, and the agency’s website. Additional updates will be posted as needed.

The rest of the Expedition 71 and NASA’s Boeing Crew Flight Test crews spent Monday on an array of physics and biology studies, as well as hardware cleanup and life support duties.

NASA Flight Engineers Tracy C. Dyson and Mike Barratt participated in eye checks on Monday for the CIPHER suite of 14 human research experiments. Dyson peered into the eyes of Barratt using standard medical imaging hardware found on Earth with real-time assistance from flight surgeons on the ground. Doctors are exploring how living in space affects eye structure and function. Dyson also stowed spacesuit components in the Quest airlock. Barratt reorganized the Permanent Multipurpose Module (PMM) to make room for the new Cygnus cargo then replaced fuel bottles inside the Combustion Integrated Rack.

Boeing Starliner Pilot Suni Williams from NASA assisted Barratt inside the PMM before working throughout the day on orbital plumbing tasks. Starliner Commander Butch Wilmore, also from NASA, installed a light meter in the Veggie space botany facility, obtained light measurements, then adjusted the light settings inside the plant research device. The duo called down to Boeing flight controllers at the end of the day and discussed mission updates.

The three Roscosmos cosmonauts had their day full as the trio tested a pressure suit and serviced life support gear. Station Commander Oleg Kononenko and Flight Engineer Alexander Grebenkin evaluated the lower body negative pressure suit and its ability to reverse the space-caused upward flow of body fluids in space crew members. The specialized suit may also help crews adapt faster to the return to Earth’s gravity. The duo then split up and serviced life support and ventilation systems in the Nauka science module. Flight Engineer Nikolai Chub also worked in Nauka photographing plumbing components before replacing air flow sensors and inspecting video hardware throughout the orbital outpost’s Roscosmos segment.

NASA’s Northrop Grumman Cygnus Completes Solar Arrays Deployment

Northrop Grumman’s Cygnus spacecraft completed the deployment of its two solar arrays at 2:21 p.m. EDT after launching at 11:02 a.m. Aug. 4 on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida to the International Space Station for NASA.

Shortly after launch, the spacecraft missed its first burn slated for 11:44 a.m. due to a late entry to burn sequencing. Known as the targeted altitude burn, or TB1, it was rescheduled for 12:34 p.m., but aborted the maneuver shortly after the engine ignited due to a slightly low initial pressure state. There is no indication the engine itself has any problem at this time.

Cygnus is at a safe altitude, and Northrop Grumman engineers are working a new burn and trajectory plan. The team aims to achieve the spacecraft’s original capture time on station, which is currently slated for 3:10 a.m. on Tuesday, Aug. 6.

If all remains on track, NASA will provide live coverage of the spacecraft’s arrival beginning at 1:30 a.m. Aug. 6 on NASA+, NASA Television, the NASA appYouTubeXFacebook, and the agency’s website. Additional updates will be posted as needed.

Preparations are underway aboard the International Space Station to capture and install a U.S. cargo craft due to arrive next week. Spacesuit checks and health studies were also on the program at the end of the week for the two crews living and working aboard the orbital outpost.

Mission managers have given the go for the launch of Northrop Grumman’s Cygnus cargo craft set for 11:29 a.m. EDT on Saturday from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. Cygnus will orbit Earth for a day-and-a-half before arriving at the orbital outpost early Monday.

Expedition 71 Engineers Matthew Dominick and Jeanette Epps will be on duty Monday monitoring Cygnus’ approach and rendezvous. Dominick will command the Canadarm2 robotic arm to reach out and grapple Cygnus at approximately 3:55 a.m. on Monday. Dominick will be inside the cupola with Epps backing him up Monday morning and keeping an eye on Cygnus as it advances toward the orbital outpost.

The duo spent Friday morning continuing to train on a computer and simulated the robotics activities necessary to capture Cygnus next week. At the end of the day, the NASA pair joined fellow astronauts Tracy C. Dyson, Mike Barratt, Butch Wilmore, and Suni Williams for a Cygnus cargo operations conference with mission controllers on the ground.

Earlier, Dyson, Wilmore, and Williams took turns throughout the day servicing a U.S. spacesuit in the Quest airlock. Dyson started the job first cleaning the spacesuit’s cooling loops. Afterward, Wilmore and Williams took over finishing up the loop cleaning job then finally deconfiguring and stowing the suit components inside Quest.

Dyson later examined the eyes of NASA Flight Engineer Mike Barratt using standard medical imaging hardware found in an optometrist’s office on Earth. Doctors on Earth guided Dyson as she peered in Barratt’s cornea, retina, and lens to understand microgravity’s effect on crew vision. Before the eye checks began, Barratt spent his day servicing a variety of research hardware including the Life Science Glovebox in the Kibo laboratory module and the CIMON mobile crew helper powered by artificial intelligence.

Wilmore and Williams, Boeing’s Crew Flight Test Commander and Pilot respectively, focused primarily on lab maintenance before they began their spacesuit work Friday afternoon. Wilmore spent some time inside the Tranquility module cleaning up cables and stowing electronics components. Williams worked during her morning inside the Columbus laboratory module installing networking gear including a video and data processing unit and a high-rate modem.

Working in the station’s Roscosmos segment, Commander Oleg Kononenko set up Earth observation hardware to study luminous clouds in Earth’s upper atmosphere. Flight Engineer Nikolai Chub started day servicing on oxygen generator, then studied the effects of magnetic and electrical fields on fluid physics, before uninstalling navigation hardware from the Progress 88 resupply ship. Flight Engineer Alexander Grebenkin spent his day working on orbital plumbing and cleaning ventilation systems while also fitting in an Earth photography session in the middle of the day.

Thursday’s main activities aboard the International Space Station on Thursday were Cygnus cargo craft preparations and microgravity science. Amidst the mission and research duties, the two crews living and working aboard the orbital outpost also kept up standard household duties and plumbing tasks.

Northrop Grumman’s Cygnus resupply ship is targeted to launch atop a SpaceX Falcon 9 rocket at 11:29 a.m. EDT on Saturday from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. Cygnus is planned to take a day-and-a-half trip around Earth before arriving at the space station for its robotic capture at 6 a.m. on Monday.

NASA Flight Engineers Matthew Dominick and Jeanette Epps practiced Cygnus capture techniques on Thursday using the Canadarm2 robotic arm and guiding it toward a grapple fixture on the Permanent Multipurpose Module (PMM). Dominick will be commanding the Canadarm2 to capture Cygnus early Monday while Epps will back him up and monitor Cygnus’ approach and rendezvous.

Epps began her day with blood and saliva sample collection work, processing the specimens for analysis, then stowing the samples in a science freezer and the Kubik research incubator for future retrieval. Dominick set up a notebook computer and connected it to the advanced resistive exercise device for an experiment that measures how muscles and bones are impacted when working out in space.

Tracy C. Dyson and Mike Barratt, both Expedition 71 Flight Engineers, worked on science maintenance and housekeeping tasks throughout the day. Dyson swapped samples and components inside a flame research device that safely studies how materials burn in weightlessness aboard the Kibo laboratory module. Barratt measured the airflow in the Harmony module’s port side crew quarters to ensure the upkeep of ventilation systems and maintain crew health.

NASA astronauts Butch Wilmore and Suni Williams, Commander and Pilot for Boeing’s Crew Flight Test, spent their day on a variety of household tasks. Wilmore first organized food stowed in the Unity module and the PMM then installed a light meter on the Veggie botany research facility. Williams deep cleaned Unity temporarily uninstalling racks and hardware to access and wipe down hard to reach areas with disinfectant.

Station Commander Oleg Kononenko from Roscosmos began his day checking laptop computers before spending the afternoon photographing crew activities and inspecting windows in the Zvezda service module. Flight Engineer Nikolai Chub was back on physics research Thursday as he studied how fluids are affected by magnetic and electrical fields in space.

Spacesuits, robotics, and maintenance were the main priorities for the Expedition 71 and NASA’s Boeing Crew Flight Test crews after the International Space Station raised its orbit on Wednesday. The nine orbital residents also split their day on a variety of human research activities and docked crew spaceship activities.

NASA Flight Engineer Matthew Dominick evaluated a spacesuit in the Quest airlock today with assistance from fellow NASA astronaut Mike Barratt. The duo powered up the spacesuit, configured its components, and tested the suit’s communications and life support systems during Dominick’s fit verification.

Astrobee free-flying robotic assistants, powered by fans and a vision-based navigation system, were maneuvering inside the Kibo laboratory module during the Astrobee Zero Robotics 3 finals competition on Wednesday. The Astrobees were controlled and manipulated by winning algorithms written by students on Earth and downloaded to the robotics platform by mission controllers. NASA Flight Engineer Tracy C. Dyson readied the toaster-sized, cube-shaped Astrobees then monitored the contest designed to encourage students to pursue careers in science, engineering, and space exploration.

During the morning, NASA Flight Engineer Jeanette Epps removed blood samples that were stowed overnight inside the Kubik research incubator. She spun those samples in a centrifuge before placing them inside a science freezer for preservation and later analysis to understand microgravity’s effect on humans. Afterward, Epps conducted several hours of airflow measurements inside the crew quarters located in the Harmony module’s deck compartment to maintain ventilation systems and crew health.

Starliner Commander Butch Wilmore and Suni Williams, both NASA astronauts, had their day packed primarily with lab upkeep duties aboard the orbiting outpost. Wilmore spent his morning inspecting advanced plumbing hardware then packed the life support components for return to Earth. Williams set up high-definition video gear inside the Columbus laboratory module then inspected a bar code reader and radio frequency hardware. The duo also partnered up and organized cargo packed inside the Tranquility module before calling down to Boeing mission controllers for a conference.

The space station is orbiting higher today after the docked Progress 87 cargo craft fired its thrusters for over 20 minutes early Wednesday morning. The orbital reboost places the station at the correct altitude to receive the next cargo craft from Roscosmos after it launches in mid-August.

Commander Oleg Kononenko examined the cargo space available inside the Nauka and Rassvet modules to prepare for the upcoming space delivery. The five-time station visitor also inspected the telerobotically operated rendezvous unit, or TORU, in the Zvezda service module. The TORU would be used to remotely control an approaching Roscosmos resupply ship in the unlikely event the spacecraft would be unable to complete its automated docking sequence.

Roscosmos Flight Engineers Nikolai Chub and Aleksander Grebenkin had their day full as they conducted a variety of space research and maintained orbital lab systems on Wednesday. Chub continued studying how magnetic and electrical fields affect fluid physics and serviced life support systems. Grebenkin pointed a digital video camera out a station window and videotaped the condition of the Roscosmos segment modules for analysis.
