Russia’s Progress 77 cargo rocket launched from its launch pad at the Baikonur Cosmodrome in Kazakhstan on Feb 14., 2021.
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.

Beginning at 11:15 p.m. EST, NASA Television will provide live coverage of the launch and docking of a Russian cargo spacecraft to the International Space Station.
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.
Resupply Rocket Rolls Out to Pad, Crew Keeps up Space Studies

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. EDT 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.
NASA Flight Engineers Michael Hopkins and Victor Glover partnered up on Friday for a pair of different experiments. The duo demonstrated how hydroponics may support space agriculture then explored how the human nervous system adapts to weightlessness.
Astronauts Kate Rubins of NASA and Soichi Noguchi of JAXA joined each other for maintenance work inside the Tranquility module. Rubins also collected microbe samples to understand how they survive and adapt on the station. NASA Flight Engineer Shannon Walker spent the day working on batteries that keep life support systems powered inside U.S. spacesuits.
Crew Preps New Airlock and Studies Variety of Space Phenomena
Expedition 64 Flight Engineer Michael Hopkins works on hydroponics components for the Plant Water Management study.
The Expedition 64 crew continued setting up a new science and cargo airlock for operations today since its installation last year on the International Space Station. The orbital residents also researched how microgravity affects humans, plants and physics.
The station’s Tranquility module was expanded in December with the addition of the new NanoRacks Bishop airlock. Flight Engineer Kate Rubins is finalizing its configuration today by connecting cables and installing components so Bishop can begin service. She was assisted by fellow NASA astronauts Shannon Walker and Victor Glover who began stowing cargo inside Bishop for the first time.
Glover started the morning with NASA Flight Engineer Michael Hopkins inside Europe’s Columbus laboratory module researching how the human nervous system adapts to weightlessness. The duo took turns seated in a specialized chair performing a series of dexterous manipulation tasks for the GRIP study. Insights may help engineers and doctors develop better spacecraft interfaces and treat neurological conditions on Earth.
Hopkins then spent the afternoon demonstrating hydroponics for the Plant Water Management study as a way to sustain plants in microgravity from germination through harvest. JAXA (Japan Aerospace Exploration Agency) Flight Engineer Soichi Noguchi jotted down his meals for the Nutrition study before swapping samples for a crystal growth/semiconductor study.
Cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov were back on exercise research today studying how the lack of gravity impacts the effectiveness of a workout. The duo strapped sensors to themselves measuring their heart and breathing rate as they jogged on the Zvezda service module’s treadmill.
Nervous System, Exercise Research Fills Science Schedule Wednesday

The space-exposed human nervous system may impact how an astronaut grips and manipulates objects during a mission. NASA Flight Engineers Michael Hopkins and Victor Glover participated in the GRIP study today that could help engineers and doctors develop better spacecraft interfaces and treat neurological conditions on Earth.
Glover also checked out components on safety jetpacks that an astronaut would use in the unlikely event a spacewalker became untethered from the space station. NASA Flight Engineer Shannon Walker worked during the afternoon on batteries that keep U.S. spacesuit life support systems powered during spacewalks.
NASA Flight Engineer Kate Rubins tried on the experimental AstroRad radiation protection vest during the afternoon testing it for fit and comfort while working. Flight Engineer Soichi Noguchi of JAXA (Japan Aerospace Exploration Agency) serviced the Cell Biology Experiment Facility, an incubator that cultivates cells and plants for research, throughout the day.
Exercise research is also important as flight surgeons learn to maximize the effects of a crew member’s workout to account for the lack of gravity. Cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov strapped sensors to themselves and jogged on the Russian treadmill on Wednesday. Data will be sent down to doctors to review how a cosmonaut’s body adjusts to working out in space.
