Two rockets on opposite sides of the world will launch to the International Space Station delivering cargo and a new crew this week. The first spaceship will launch from Kazakhstan Tuesday night hauling supplies to replenish the Expedition 69 crew. The second will launch from Florida sending four new crew members to the orbital lab.

The Roscosmos Progress 85 cargo craft is counting down to a launch at 9:08 p.m. EDT tonight from the Baikonur Cosmodrome in Kazakhstan. It will orbit Earth for two days before docking to the aft port of the Zvezda service module at 11:50 p.m. on Thursday. A few hours later on Friday, cosmonauts Sergey Prokopyev and Dmitri Petelin will open Progress 85’s hatches and begin unpacking about three tons of food, fuel, and supplies.

Four Commercial Crew astronauts were suited up inside the SpaceX Dragon Endurance spacecraft at NASA’s Kennedy Space Center in Florida overnight for their dry dress launch countdown. A few hours later, the Falcon 9 engines fired for 6 seconds as part of the pre-launch static fire test. SpaceX Crew-7 is slated to launch at 3:49 a.m. on Friday.

Crew-7 Commander Jasmin Moghbeli of NASA will lead Pilot Andreas Mogensen of ESA (European Space Agency), and Mission Specialists Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) and Konstantin Borisov of Roscosmos during their ride to the orbital lab. The quartet, inside the Endurance, will dock to the Harmony module’s space-facing port at 2:02 a.m. on Saturday beginning a six-month space research mission.

Back aboard the orbital outpost on Tuesday, the seven crewmates from the U.S., UAE (United Arab Emirates), and Russia stayed focused on microgravity research and lab maintenance.

NASA Flight Engineers Frank Rubio and Stephen Bowen swapped out hardware inside the Fluids Integrated Rack for a boiling and condensation study that may improve thermal systems on Earth and in space. Rubio earlier joined UAE astronaut Sultan Alneyadi organizing cargo inside the Northrop Grumman Cygnus space freighter. Bowen began his day cleaning crew quarters ventilation systems and checking airflow sensors. Flight Engineer Woody Hoburg of NASA also assisted with the Cygnus work before configuring the Tranquility module’s Bishop airlock ahead of its depressurization.

Prokopyev attached sensors to himself for a long-running Roscosmos heart study during the morning. He later joined Petelin for ultrasound scans to observe how the digestive system adapts to weightlessness. Roscosmos Flight Engineer Andrey Fedyaev worked on orbital plumbing tasks inside the Nauka science module.

At the end of the day, Fedyaev joined Bowen, Hoburg, and Alneyadi to prepare for their upcoming departure on Sept. 1 inside the SpaceX Dragon Endeavour spacecraft and splashdown off the coast of Florida about 24 hours later. The quartet called down to ground specialists and discussed spacecraft operations during their return to Earth.

Botany and physics topped the research schedule as spacewalk cleanup duties continued aboard the International Space Station on Friday. The Expedition 69 crew also focused on life support maintenance as a U.S. cargo craft fired it engines to boost the orbital outpost.

Sustaining crews independently of cargo missions and taking advantage of microgravity for better manufacturing techniques are key targets for NASA’s and its international partners’ research programs. Friday’s science specifically looked at growing crops in space and advancing manufacturing techniques.

NASA Flight Engineer Frank Rubio set up seed bags for the Plant Habitat-03B study to understand how characteristics of plants grown in space change from one generation to the next. Results may inform ways to grow repeated generations of space crops to support future crewed missions. UAE (United Arab Emirates) astronaut Sultan Alneyadi worked in the Microgravity Science Glovebox servicing samples to learn how to manufacture superior graphene aerogel in microgravity. The SUBSA-μgGA physics study seeks to benefit Earth and space industries for better power storage, environmental protection, and chemical sensing.

The duo also assisted NASA Flight Engineer Woody Hoburg who worked throughout Friday swapping life support gear in the Tranquility module. A failed heat exchanger was removed and a new one was installed then connected to new low temperature loop hoses. NASA Flight Engineer Stephen Bowen aided his crewmates on Friday photographing Alneyadi’s research work and helping Hoburg during his life support maintenance. Bowen later removed sensors that measured his blood pressure and downloaded the data to doctors on the ground.

Cosmonauts Sergey Prokopyev and Dmitri Petelin continued cleaning their spacesuits and stowing tools and accessories following Wednesday’s spacewalk to install orbital debris shields and relocate a portable workstation. Roscosmos Flight Engineer Andrey Fedyaev assisted with the spacewalk cleanup work finalizing operations with the European robotic arm and stowing medical kits on Friday.

The Northrop Grumman Cygnus cargo spacecraft’s delta velocity thruster fired at 10:35 a.m. EDT Friday for 22 minutes, 48 seconds in a reboost of the International Space Station. The planned maneuver was designed to further refine the phasing for the Roscosmos Progress 85 cargo spacecraft launch on Tuesday, Aug. 22, from the Baikonur Cosmodrome in Kazakhstan, and its docking to the station Thursday, Aug. 24. It was one of two scheduled reboosts to target the proper trajectory for the Roscosmos Soyuz MS-24 launch and two-orbit rendezvous to the orbiting complex on Sept. 15, as well as the Soyuz MS-23 undocking and landing on Sept. 27.

The reboost also continued the certification of the use of Cygnus as a second spacecraft currently capable of conducting such a maneuver. The Cygnus reboost increased the station’s altitude by 3/10 of a mile at apogee and 2.8 miles at perigee and put the space station in an orbit of 262.5 x 257.6 statute miles.

Crew members who will soon fly aboard NASA’s SpaceX Crew-7 mission will enter quarantine Friday in one of the major milestones before they head to the launch site in Florida to start their mission to the International Space Station. The company’s Falcon 9 rocket is targeted to launch Crew-7 no earlier than 3:49 a.m. EDT on Friday, Aug. 25 from Launch Complex 39A at Kennedy.

The Expedition 69 crew is continuing to unpack a U.S. cargo craft before it fires engines to reboost the International Space Station on Friday. The orbital residents are also continuing their science and maintenance activities while cleaning up the day after a spacewalk.

NASA astronauts Frank Rubio and Stephen Bowen continued unpacking some of the several tons of science and supplies still packed inside the Cygnus space freighter on Thursday. Cygnus will also fire it engines on Friday reboosting the orbital outpost. This will raise the station to the correct altitude for the upcoming arrival of a Roscosmos cargo craft in two weeks. The station will also be in the proper phasing for a Soyuz crew swap mission planned in mid- to late September.

Rubio also opened up the Combustion Integrated Rack to troubleshoot the computer electronics inside. Bowen monitored his blood pressure throughout the day and swapped samples in the Microgravity Science Glovebox for a space manufacturing study.

NASA Flight Engineer Woody Hoburg spent his day on inflight maintenance as he replaced charcoal filters in the Harmony module and loaded new software on a tablet computer. UAE (United Arab Emirates) astronaut Sultan Alneyadi organized food bags, helped Rubio unload the Cygnus cargo craft, then finally replaced window scratch panes in the cupola.

Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin are cleaning their Orlan spacesuits and stowing spacewalking gear following Wednesday’s spacewalk. The duo spent six hours and 35 minutes in the vacuum of space installing orbital debris shields and relocating a portable workstation on the Roscosmos segment of the space station.

Flight Engineer Andrey Fedyaev is returning the European robotic arm (ERA) to its stowage configuration on the Nauka science module.  Fedyaev commanded the ERA during Wednesday’s spacewalk moving the workstation from the Rassvet module to Nauka and testing its ability to maneuver a spacewalker with Prokopyev attached for the first time.

The Roscosmos trio got a late start on Thursday after sleeping in following a good night’s rest. During their cleanup activities, Prokopyev and Petelin also called down to mission controllers to discuss the previous day’s spacewalk activities.

Stem cells and space botany were the top research objectives for the Expedition 69 crew on Tuesday while still working to unpack a new U.S. cargo craft. Two cosmonauts are also “go” to exit the International Space Station on Wednesday for more upgrades on the orbital lab.

Life science in microgravity enables researchers to observe biological phenomena and achieve unique insights that would be impossible in Earth’s gravity environment. Scientists then apply the new knowledge potentially improving a variety of Earth-bound conditions including human health and agriculture.

Two experiments aboard the station today addressed new cancer therapies and ways to grow crops in space. NASA Flight Engineer Frank Rubio worked in the Kibo laboratory module servicing stem cell samples for the StemCellEX-H Pathfinder study that seeks to improve therapies for blood diseases and cancers such as leukemia. UAE (United Arab Emirates) astronaut Sultan Alneyadi harvested leaves from thale cress plants that are similar to cabbage and mustard for the Plant Habitat-03 experiment to learn how to grow food and sustain crews on future space missions.

NASA astronauts Stephen Bowen and Woody Hoburg focused their day primarily on orbital maintenance. Bowen replaced air filters in the Destiny laboratory module while Hoburg monitored the performance of the advanced resistive exercise device for troubleshooting in the Tranquility module. The duo also had time set aside for some science activities as Bowen processed his blood samples for analysis and Hoburg tested station potable water samples for quality.

All four astronauts continued unpacking some of the 8,200 pounds of science and supplies delivered aboard the Cygnus space freighter on Friday. Cargo activities will be ongoing until late October when Cygnus departs the station completing a three-month orbital stay.

Two cosmonauts are ready to begin the 10th spacewalk at the station this year to install orbital debris shields and relocate hardware on the orbital outpost’s Roscosmos segment. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin have completed their procedure reviews and Orlan spacesuit configurations and will begin a six-and-a-half-hour spacewalk at 10:45 a.m. EDT on Wednesday. NASA TV, on the agency’s app and website, begins its live spacewalk coverage at 10:15 a.m.

Flight Engineer Andrey Fedyaev will support the two spacewalkers on Wednesday as he commands the European robotic arm (ERA) from inside the Nauka science module during the planned six-hour and 30-minute excursion. Fedyaev started his day joining Prokopyev and Petelin for the final spacewalk procedures review. He then spent the rest of the day configuring the ERA preparing it for hardware transfers during Wednesday’s spacewalk.

The Cygnus cargo craft approaches the International Space Station on Aug. 4 while orbiting 261 miles above the coast of the Garabogazköl Basin in Turkmenistan.

A U.S. cargo craft is open for business at the International Space Station and two cosmonauts are gearing up for a spacewalk on Wednesday. The Expedition 69 crew also kicked off the work week exploring high temperature physics and ways to make semiconductor crystals.

NASA Flight Engineer Frank Rubio worked throughout Monday unpacking some of the 8,200 pounds of science and supplies delivered aboard Northrop Grumman’s Cygnus space freighter on Friday. A couple of the new experiments include investigations looking at the formation of 3D neuron cell structures and an Astrobee robotic free-flyer to assist astronauts. News crew supplies include food, water, life support gear, and spacewalking hardware.

Flight Engineers Stephen Bowen of NASA and Sultan Alneyadi of UAE (United Arab Emirates) worked on a pair of different space physics investigations on Monday. Bowen swapped out samples inside the Electrostatic Levitation Furnace that explores the thermophysical properties of materials subjected to high temperatures in microgravity. Alneyadi set up new hardware in the Microgravity Science Glovebox to improve the technology of producing semiconductor crystals.

NASA Flight Engineer Woody Hoburg began his day on science maintenance work swapping out research gear and inspecting a rack in the Columbus laboratory module. He also serviced new Cold Atom Lab hardware inside the Destiny laboratory module. The Cold Atom Lab observes the quantum behavior of atoms chilled to temperatures near absolute zero. Hoburg also joined his crewmates and assisted Rubio as he unloaded cargo from inside Cygnus.

Two cosmonauts are in final preparations for the year’s 10th spacewalk out of the station set to begin at 10:45 a.m. on Wednesday. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin will exit the Poisk airlock in their Orlan spacesuits and spend about six and a half hours installing micrometeoroid orbital debris shields and relocating hardware. The duo from Roscosmos spent Monday configuring communications gear and checking their spacesuits for leaks. This will be Prokopyev’s and Petelin’s sixth spacewalk together since their first on Nov. 17, 2022.

Roscosmos Flight Engineer Andrey Fedyaev spent his day primarily on life support tasks. He started Monday replacing heat exchanger fans in the Nauka science module. In the afternoon, Fedyaev worked on the Zvezda service module’s Elektron oxygen generator that splits reclaimed water into oxygen and hydrogen.

On Aug. 5, the Progress 83 spacecraft’s thrusters fired for three minutes, 16 seconds in a planned avoidance maneuver to provide the International Space Station an extra measure of distance away from a predicted track of a debris fragment.

The thruster firing occurred at 10:03 p.m. EDT, and the maneuver had no impact on station operations, including the trajectory phasing for either the upcoming Roscosmos Progress 85 cargo launch on Tuesday, Aug. 22, and SpaceX Crew-7 launch on Aug. 25.

A wide variety of research kept the Expedition 69 crew busy aboard the International Space Station on Thursday. In the meantime, the orbital residents will welcome a U.S. cargo craft on Friday then turn their attention to a spacewalk next week.

Four astronauts from NASA and the UAE (United Arab Emirates) were back to work following a day off on Wednesday. The quartet had its hands full on Thursday studying how microgravity affects biology, physics, and robotics.

Flight Engineer Stephen Bowen serviced blood samples to assess how the immune system changes in weightlessness. Flight Engineer Frank Rubio swapped samples inside the Materials Science Laboratory, a research facility designed to discover new applications for existing materials and new or improved materials. Flight Engineer Woody Hoburg monitored the Astrobee robotic assistants that were controlled by student-written algorithms in support of the Astrobee-Zero Robotics competition for youth. Astronaut Sultan Alneyadi worked throughout the day on life support maintenance before familiarizing himself with the BioFabrication Facility, a 3D biological printer.

After the science work, all four flight engineers joined each other and called down to the next crew to visit the station, SpaceX Crew-7, and discussed the crew swap targeted for the end of the month. Finally, the foursome wrapped up its day with a conference with mission controllers to discuss Cygnus’ arrival on Friday.

Cygnus is due to be captured at 5:55 a.m. EDT on Friday when Hoburg commands the Canadarm2 robotic arm to reach out and grapple the U.S. resupply ship. Rubio will be backing up Hoburg monitoring Cygnus as it arrives packed with over 8,200 pounds of science and supplies. Cygnus began its trip to the station after launching at 8:31 p.m. on Tuesday from NASA’s Wallops Flight Facility in Virginia.

Just five days after Cygnus arrives, Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin will exit the Poisk airlock in their Orlan spacesuits for the year’s 10th spacewalk. They have been reviewing procedures this week for when they install micrometeoroid orbital debris shields and relocate hardware on the outside of the orbital lab on Aug. 9.

The duo from Roscosmos took a break from spacewalk preparations today and studied how living in space affects digestion and ways future crews may pilot planetary spacecraft and robots. Flight Engineer Andrey Fedyaev also participated in the space digestion study before attaching electrodes to himself for a 24-hour session measuring his heart activity and blood pressure.
