The unpiloted Russian Progress 77 cargo spacecraft undocked from the International Space Station while attached to the Pirs docking compartment at 6:55 a.m. EDT.
The spacecraft will reenter Earth’s atmosphere and harmlessly burn up over the south Pacific. The mission launched and docked to the space station in February delivering more than a ton of cargo to the Expedition 65 crew. Deorbit and re-entry will not be covered on NASA TV.
With the port on the Earth-facing side of the Russian segment station vacated by the departure of Pirs and Progress, Russia’s Multipurpose Laboratory Module (MLM) is scheduled to dock at the station Thursday, July 29. Named Nauka, after the Russian word for “science,” MLM launched on July 21 and will serve as a new science facility, docking port, and spacewalk airlock for future operations.
Science also continued aboard the orbiting laboratory, with NASA Flight Engineer Mark Vande Hei conducting experiment runs throughout the day for Investigating the Structure of Paramagnetic Aggregates from Colloidal Ellipsoids, or InSPACE-4. This investigation studies the assembly of tiny structures from colloids using magnetic fields. Off the Earth and without the constraints of gravity, scientists are able to observe the assembly processes free from confining sample walls and sedimentation and to timescales not possible during simulation.
Vande Hei teamed up with fellow crewmate Shane Kimbrough to perform needed maintenance to the station’s toilet system, removing and replacing a hose for the assembly and completing a motor test and leak check. Station Commander Akihiko Hoshide, a Japan Aerospace Exploration Agency astronaut, along with NASA astronaut Megan McArthur, helped keep station experiments running optimally by removing two deployers from the Japanese Experiment Module Small Satellite Orbital Deployer and a hard drive from the Fluids and Combustion Facility, respectively.
Cosmonauts Pyotr Dubrov and Oleg Novitskiy, meanwhile, worked to transfer equipment for disposal to the Progress 77 cargo craft, which is set to undock — along with the Pirs Docking Compartment — from the International Space Station on Friday, July 23. A few hours later, Progress’ engines will fire in a deorbit maneuver to send the cargo craft and Pirs into a destructive re-entry in the Earth’s atmosphere over the Pacific Ocean.
Replacing Pirs, a module that has been part of the orbital outpost for the past 20 years, is the Multipurpose Laboratory Module (MLM) named Nauka, the Russian word for “science.” The MLM is scheduled to launch on Wednesday, July 21, on a three-stage Proton rocket from the Baikonur Cosmodrome in Kazakhstan.
Most pressing for the team in space was a comprehensive onboard training session and simulation for the upcoming Crew Dragon port relocation, which will set the stage for a historic first — when two different U.S. commercial spacecraft built for crew will be docked to the outpost at the same time.
See all these mission events on NASA Television, the NASA app, and the agency’s website. Live coverage of the port relocation begins at 6:30 a.m. EDT Wednesday, July 21, with launch coverage of the MLM at 10:30 a.m. that same day. On Friday, July 23, coverage for the undocking of Progress 77 and Pirs beginning at 8:45 a.m. EDT Friday, July 23.
An uncrewed Russian Progress 78 spacecraft arrived at the International Space Station’s Poisk module on the space-facing side of the Russian segment at 8:59 p.m. EDT, two days after lifting off from the Baikonur Cosmodrome in Kazakhstan Sunday, Tuesday June 29 at 7:27 p.m. (4:27 a.m. Wednesday, June 30, Baikonur time). The spacecraft were flying over southeast Pacific Ocean off the coast of Chile at the time of docking.
Carrying more than 3,600 pounds of food, fuel, and supplies for the Expedition 65 crew, the Progress 78 resupply spacecraft will spend almost five months at the station. The cargo craft is scheduled to perform an automated undocking and relocation to the new “Nauka” Multipurpose Laboratory Module in late October. Named for the Russian word for “science,” Nauka is planned to launch to the space station in July.

The Expedition 64 crew is getting ready for next week’s arrival of the Northrop Grumman Cygnus resupply ship following its launch on Saturday. The orbital residents are also maintaining science operations and unpacking a new Russian spacecraft at the International Space Station.
The Antares rocket with the Cygnus space freighter atop rolled out to its launch pad on Tuesday at Wallops Flight Facility in Virginia. The spacecraft will blast off on Saturday at 12:36 p.m. EST carrying about 8,000 pounds of science experiments, station hardware and crew supplies for the orbital lab. NASA TV will broadcast the launch activities live beginning at 12 p.m.
Flight Engineers Soichi Noguchi and Michael Hopkins will be on duty Monday morning when Cygnus arrives for its approach and capture. Noguchi of JAXA (Japan Aerospace Exploration Agency) will command the Canadarm2 robotic arm to capture Cygnus at about 4:40 a.m. Hopkins of NASA will monitor Cygnus’ approach and rendezvous as it reaches a point about 10 meters from the station.
The duo was joined Thursday afternoon by NASA astronauts Kate Rubins, Shannon Walker and Victor Glover to review the upcoming Cygnus cargo operations. Afterward, the quintet called down to mission controllers to discuss unpacking and activating some of the critical science experiments arriving on the U.S. space freighter.
Combustion research and eye checks were also on the schedule aboard the station on Thursday. Walker and Hopkins partnered up on a study observing how flames spread in microgravity. Rubins took charge of eye exams and checked the eyes of Glover and Noguchi using optical coherence tomography.
Russia’s ISS Progress 77 resupply ship delivered over a ton of nitrogen, propellant and oxygen early Wednesday morning to the International Space Station. Northrop Grumman’s Cygnus space freighter is up next as it counts down to this weekend’s launch from Virginia to the orbiting lab.
The Progress 77 docked to the Pirs docking compartment on Wednesday at 1:27 a.m. EST following a two-day trip that began with a launch from the Baikonur Cosmodrome in Kazakhstan. Commander Sergey Ryzhikov remotely guided the Progress 77 to its docking port with the TORU (tele-robotic rendezvous system) after the vehicle automatically switched over from the Kurs automated rendezvous system.
Ryzhikov and Flight Engineer Sergey Kud-Sverchkov then began a series of hours-long leak and pressure checks with the Progress 77. The duo finally opened the hatch to the new Russian cargo craft to begin transferring its cargo. Progress 77 will stay at the station for about 5 months when it will finally detach Pirs from the Zvezda service module’s Earth-facing port opening it up for the new Nauka multipurpose laboratory module.
Northrop Grumman is readying its next Cygnus cargo mission to launch this Saturday at 12:36 p.m. atop the Antares rocket from NASA’s Wallops Flight Facility in Virginia. Cygnus will be packed with about 8,000 pounds of science experiments, station hardware and crew supplies destined for the Expedition 64 crew.
Cygnus will orbit the Earth for nearly two days before its rendezvous with the station on Feb. 22. JAXA (Japan Aerospace Exploration Agency) astronaut Soichi Noguchi will be on robotics duty early Monday and command the Canadarm2 robotic arm to capture Cygnus at about 4:40 a.m. NASA Flight Engineer Michael Hopkins will back him up monitoring Cygnus’ approach and rendezvous.
An uncrewed Russian Progress 77 carrying just over one ton of nitrogen, water and propellant to the International Space Station launched from the Baikonur Cosmodrome in Kazakhstan at 11:45 p.m. EST (9:45 a.m. Monday, Feb. 15, Baikonur time).
The resupply ship reached preliminary orbit and deployed its solar arrays and navigational antennas as planned for a two-day rendezvous on its way to meet up with the orbiting laboratory and its Expedition 64 crew members.
After making 33 orbits of Earth on its journey, the spacecraft will automatically dock to the station’s Pirs docking compartment on the Russian segment at 1:20 a.m. Wednesday, Feb. 17. Live coverage on NASA TV of rendezvous and docking will begin at 12:30 a.m.
The uncrewed Russian Progress 77 is scheduled to lift off on a Soyuz rocket at 11:45 p.m. (9:45 a.m. Monday, Feb. 15, Baikonur time) from the Baikonur Cosmodrome in Kazakhstan to begin a two-day journey to the orbiting laboratory.
The next rocket to launch a resupply ship to the International Space Station rolled out to its launch pad on the other side of the world this morning. Back on the orbiting lab, the seven-member Expedition 64 crew kept up its space studies while servicing U.S. spacesuits.
Russia’s ISS Progress 77 cargo craft is standing atop its rocket at the Baikonur Cosmodrome launch pad in Kazakhstan. It is counting down to liftoff on Sunday at 11:45 p.m. EST to deliver just over one ton of nitrogen, water and propellant to the station. It will dock Tuesday at 1:20 a.m. to the Pirs docking compartment.
The Progress 77 will later detach Pirs from the station readying the Zvezda service module’s port for a new module. Pirs will then be replaced with the Nauka multipurpose laboratory module to be delivered on a Proton rocket. The Pirs undocking occurs a few days after Nauka’s launch to enable Russian flight controllers to confirm a good vehicle in orbit heading to the station.
In the meantime, science is the main mission aboard the station. Microgravity research has the potential to reveal new insights and potential therapies that otherwise wouldn’t be possible on Earth due to gravity’s interference.
