The SpaceX Dragon Freedom spacecraft approaches the International Space Station for a docking on Sept. 29, 2024.
Protecting eyesight to keep crews healthy and packing cargo for an upcoming mission were the main tasks for the Expedition 72 crew aboard the International Space Station on Tuesday.
Body fluids behave differently in weightlessness resulting in an upward flow toward an astronaut’s head. This condition creates pressure on a crew member’s eyes causing changes in eye structure and vision. Commander Suni Williams and Flight Engineer Butch Wilmore, both NASA astronauts, tested a specialized thigh cuff throughout the day that may prevent the headward fluid shifts. Researchers are monitoring these fluid shifts to learn how to safeguard eye health as NASA and its international partners plan longer missions farther out into space.
Back on Earth, the next resupply mission to the orbital outpost is getting ready for launch next week aboard the SpaceX Dragon cargo spacecraft. NASA Flight Engineers Don Pettit and Nick Hague geared up on Tuesday for the arrival of Dragon and its shipment of new science experiments and station hardware. Pettit began packing and staging cargo that will be stowed inside Dragon after its arrival then returned to Earth for retrieval. Hague trained to use the tools that will monitor the automated approach and rendezvous of Dragon.
However, before the cargo mission blasts off toward the space station, Hague will lead Williams, Wilmore, and Roscosmos cosmonaut Aleksandr Gorbunov on a short ride aboard the SpaceX Dragon Freedom spacecraft to a new docking port. The quartet will board Dragon on Sunday, Nov. 3, undock from the Harmony module’s forward port at 6:35 a.m. EST, then maneuver the spacecraft to Harmony’s space-facing port for a docking at 7:18 a.m. The relocation opens up the forward port for the Dragon cargo mission.
After a training session at the beginning of his shift on the Destiny laboratory module’s exercise cycle, Gorbunov installed and activated hardware to observe Earth’s nighttime atmosphere in near-ultraviolet wavelengths. His fellow cosmonauts Alexey Ovchinin and Ivan Vagner partnered together on maintenance and inspection duties in the aft end of the Zvezda service module.

After 236 days in space, NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin, are less than an hour away from returning to Earth on the agency’s SpaceX Crew-8 mission.
The SpaceX Dragon spacecraft completed its deorbit burn as expected ahead of splashdown targeted for approximately 3:29 a.m. EDT off the coast of Pensacola, Florida.
Upon splashdown, Crew-8 will have orbited the Earth 3,776 times and traveled approximately 100,132,895 statute miles. In their 232 days spent aboard the space station, they also saw the arrival and departure of eight visiting spacecraft.
Four minutes before splashdown, the drogue parachutes will deploy at about 18,000 feet in altitude while Dragon is moving approximately 350 miles per hour. Less than a minute later, the main parachutes will deploy at about 6,000 feet in altitude while the spacecraft is moving approximately 119 miles per hour.
NASA’s live coverage will continue on NASA+ and the agency’s website until the crew is recovered from the spacecraft.

Dragon spacecraft operations were underway aboard the International Space Station on Friday as four crew members prepare to return to Earth and another quartet prepares to swap docking ports. Meanwhile, microgravity science continued apace as the Expedition 72 crew explored how weightlessness affects stem cells, plant growth, and equilibrium.
NASA’s SpaceX Crew-8 mission is about to complete a seven-month mission aboard the orbital outpost that began on March 3. The homebound quartet, with NASA astronauts Matthew Dominick, Mike Barratt, and Jeanette Epps and Roscosmos cosmonaut Alexander Grebenkin, completed final reviews on Friday for their departure aboard the Dragon Endeavour spacecraft targeted for Sunday at 6:05 a.m. EDT.
NASA+ will stream Crew-8’s hatch closing and undocking from the Harmony module’s space-facing port beginning at 4 a.m. on Sunday. NASA+ will also start its live coverage of Crew-8’s return to Earth at 2:30 p.m. on Monday before Dragon splashes down at 3:38 p.m., pending weather. Learn how to watch NASA content through a variety of platforms, including social media.
The most recent Dragon spacecraft to visit the orbital outpost, Freedom, will switch docking ports a few days after Endeavour competes its mission. Crew-9 Commander Nick Hague from NASA will lead NASA astronauts Suni Williams and Butch Wilmore along with cosmonaut Aleksandr Gorbunov aboard Freedom during the quick ride from Harmony’s forward port to the port vacated by Crew-8. The foursome spent about an hour on Friday training for their relocation activities. NASA+ will cover the relocation activities live when mission managers finalize a time and date for Dragon’s port switch.
The Dragon crew members are still a part of the 11-member Expedition 72 crew and kept up their advanced space research activities on Friday helping NASA and its international partners keep humans healthy on and off the Earth. Williams and Wilmore serviced stem cell samples for microscope operations to learn how to treat blood diseases and cancers. Dominick and Epps were back on space botany research investigating how plants absorb water in space to support self-sufficient missions farther away from Earth. Barratt uninstalled and stowed hardware that enabled observations of how plants grow in the microgravity and radiation environment. Finally, Hague joined NASA Flight Engineer Don Pettit, who arrived at the orbiting lab aboard the Soyuz MS-26 crew ship, for eye scans with the Ultrasound 2 device.
The two cosmonauts who launched to space with Pettit, Flight Engineers Alexey Ovchinin and Ivan Vagner, took turns exploring how the lack of gravity affects their sense of balance, vision, and other sensory cues. The pair attached sensors near their eyes and ears and wore virtual reality goggles that tracked their eye movements to improve astronaut training and adaptation and promote therapies for patients on Earth.

Northrop Grumman’s Cygnus spacecraft launches atop a SpaceX 9 Falcon rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida on Sunday, Aug. 4, 2024.
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 SpaceX 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 app, YouTube, X, Facebook, 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.
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 app, YouTube, X, Facebook, and the agency’swebsite. Additional updates will be posted as needed.
NASA astronaut Matthew Dominick will capture Cygnus using the station’s Canadarm2 robotic arm at approximately 3:10 a.m., and NASA astronaut Jeanette Epps is backup. After capture, the spacecraft will be installed on the Unity module’s Earth-facing port.
This is Northrop Grumman’s 21st commercial resupply mission for NASA.

In 2022 and 2023, NASA awarded Collins Aerospace two task orders under the agency’s xEVAS (Exploration Extravehicular Activity Services) contract. The first task order was to deliver a next generation spacesuit and spacewalking system for potential use on the International Space Station with a base value of $97.2 million. The second task order was to advance additional spacesuit capabilities with a base value of $5 million.
After a thorough evaluation, NASA and Collins Aerospace have mutually agreed to descope the existing task orders on the Collins Exploration Extravehicular Activity Services contract. This descope includes ending the International Space Station suit demonstration, which was targeted for 2026. No further work will be performed on the task orders. This action was agreed upon after Collins recognized its development timeline would not support the space station’s schedule and NASA’s mission objectives.
This change to the xEVAS contract has no impact on NASA’s spacewalking capabilities on the space station. Collins will continue to support NASA’s EMU (Extravehicular Activity Mobility Unit) spacesuit and is committed to supporting space station’s ongoing spacewalking capabilities through the existing Extravehicular Space Operations Contract.
The first rays of an orbital sunrise reflect off the International Space Station’s roll-out solar arrays that overshadow and augment the orbital outpost’s main solar arrays.
Six NASA astronauts aboard the International Space Station had a day filled with cargo packing, orbital plumbing, and a spacewalk conference. The orbital outpost’s three cosmonauts from Roscosmos spent their day testing a 3D printer, collecting microbial air samples, and servicing life support gear.
In the midst of the cargo work, Dominick videotaped the location of station hardware stowed in the starboard side of the Columbus laboratory module. Epps swapped sample cartridges inside the Materials Science Laboratory, a research furnace that safely exposes metals, alloys, polymers, and other materials to high temperatures to discover new applications for Earth and space industries. Dyson and Barratt continued spacesuit and tool configurations in the Quest airlock.
At the end of the workday, the four NASA astronauts gathered in the Destiny laboratory module for a video conference with mission controllers on the ground. The quartet called down to the NASA engineers and discussed procedures and readiness for an upcoming spacewalk.
NASA’s Boeing Crew Flight Test astronauts Butch Wilmore and Suni Williams started their morning with exercise sessions before organizing cargo packed inside the Permanent Multipurpose Module. The duo then spent the afternoon working to remove and replace a failed pressure control and pump assembly module that is part of the Tranquility module’s bathroom, or waste and hygiene compartment.
Station Commander Oleg Kononenko from Roscosmos spent all day Wednesday testing a 3D printer and its ability to manufacture space hardware on demand. Flight Engineer Nikolai Chub spent half his day servicing plumbing hardware in the Nauka science module before working out on the advanced resistive exercise device and jogging on a treadmill during the afternoon. Flight Engineer Alexander Grebenkin’s list of duties included collecting more microbial air samples for analysis and maintaining electronics systems.

The Expedition 71 crew members are relaxing today following the delay of Thursday’s spacewalk. Mission planners rescheduled the spacewalk for June 24 when two spacewalkers will remove faulty radio hardware and swab station surfaces for microorganisms. A second spacewalk to remove and replace a gyroscope assembly, relocate an antenna, and prepare for future Alpha Magnetic Spectrometer upgrades is planned for July 2. Meanwhile, the two Boeing Crew Flight Test astronauts from NASA continued vehicle testing.
NASA and Boeing will discuss Starliner’s mission and departure from the International Space Station as part of the agency’s Boeing Crew Flight Test in a pre-departure media teleconference at 12 p.m. EDT Tuesday, June 18. Butch Wilmore and Suni Williams, who have previously visited the orbital outpost, called down to Boeing mission controllers on Friday and discussed their upcoming departure. Afterward, the duo entered Starliner and reviewed the spacecraft’s flight operations and procedures.
Roscosmos’ Progress 87 resupply ship, docked to the Zvezda service module, will fire its engines late Friday night boosting the space station’s orbit. The reboost maneuvers occur regularly restoring the orbiting lab’s altitude as it degrades over time due to Earth’s gravity and atmospheric drag.
The three cosmonauts working aboard the space station stayed busy on Friday with their standard complement of space research and life support maintenance duties. Commander Oleg Kononenko and Flight Engineer Nikolai Chub wrapped their work shift with eye scans using a medical imaging device looking at the retina, optic nerve, and cornea. Flight Engineer Alexander worked throughout the day on computer maintenance, vent cleaning, and orbital plumbing.
