The crew members first opened the hatch between the space station and the pressurized mating adapter at 7:05 a.m. EDT then opened the hatch to Crew Dragon.
NASA TV will continue to provide live coverage through the welcoming ceremony with leadership from NASA, ESA and JAXA to greet the crew on station. The welcome ceremony is targeted to begin about 7:45 a.m. with the following participants:
Steve Jurczyk, acting NASA administrator
Kathy Lueders, associate administrator, Human Exploration and Operations Mission Directorate, NASA Headquarters
NASA astronauts Shane Kimbrough and Megan McArthur, along with JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide, and ESA (European Space Agency) astronaut Thomas Pesquet arrived at the International Space Station Saturday, as the SpaceX Crew Dragon Endeavour docked to the complex at 5:08 a.m. EDT while the spacecraft were flying 264 miles above the Indian Ocean.
Following Crew Dragon’s link up to the Harmony module, the astronauts aboard the Endeavour and the space station will begin conducting standard leak checks and pressurization between the spacecraft in preparation for hatch opening scheduled for 7:15 a.m.
Five Expedition 65 astronauts are off-duty today relaxing one day before four Commercial Crew astronauts launch toward the International Space Station. The orbiting lab’s two cosmonauts focused on Russian science and life support maintenance tasks throughout Thursday.
NASA Commander Shannon Walker and Flight Engineers Michael Hopkins, Victor Glover and Mark Vande Hei of NASA including Soichi Noguchi of the Japan Aerospace Exploration Agency (JAXA) took it easy on the station today. The quintet is relaxing before gearing up for six days of crew swap activities. They will get back to work on Friday with more space research and preparations for the arrival of the SpaceX Crew-2 astronauts early Saturday.
The new quartet’s arrival will set in motion the next crew swap as the SpaceX Crew-1 astronauts turn their attention toward returning to Earth on April 28. Hopkins will lead his crewmates Glover, Walker and Noguchi as they undock from the station then parachute inside the Crew Dragon Resilience to a splashdown off the coast of Florida just a few hours later.
Vande Hei will stay behind with Novitskiy, Dubrov and the four SpaceX Crew-2 astronauts. They will remain at the station as the Expedition 65 crew until the next series of crew swaps planned for later this year begins.
Blood samples, muscle scans and exercise were the subjects of Tuesday’s space research to learn how the human body adapts to weightlessness. To start the day, Flight Engineers Michael Hopkins and Soichi Noguchi collected their blood samples and stowed them in a science freezer for later analysis. Hopkins then joined Flight Engineer Victor Glover for muscle scans using an ultrasound device to understand how space impacts muscle tone, stiffness and elasticity.
NASA astronaut Mark Vande Hei, who is in his second week aboard the station, attached sensors to his chest and worked out on a stationary bike for another human research experiment during the day. The exercise study measures an astronaut’s aerobic capacity and the effort required to perform strenuous activities such as spacewalks.
Another muscle study is observing changes in the genetic expression of muscles that take place in microgravity. Station Commander Shannon Walker of NASA peered at tiny worms in a microscope and recorded video as they wriggled through a specialized device that measures muscle strength. Muscle proteins change in space affecting muscle mass and strength and scientists are exploring therapies to offset this loss.
Cosmonauts Oleg Novitskiy and Pyotr Dubrov juggled a variety of science and maintenance tasks in the station’s Russian segment today. Novitskiy powered down an atmospheric study then configured communications and ventilation gear. Dubrov inspected areas in the Russian modules and studied ways to maximize a workout in space.
NASA and SpaceX mission managers are “go” for Thursday’s launch at 6:11 a.m. EDT of four Crew-2 astronauts to the space station. NASA astronauts Shane Kimbrough and Megan McArthur will occupy the commander and pilot seats respectively inside the Crew Dragon Endeavour during the ride to their new home in space. They will be flanked by Mission Specialists Akihiko Hoshide and Thomas Pesquet when they dock on Friday at 5:30 a.m. to the Harmony module’s forward-facing international docking adapter. NASA TV will broadcast the Crew-2 mission continuously from launch to docking beginning Thursday at 2 a.m.
The next crew to launch to the International Space Station is counting down to liftoff this Thursday from the Kennedy Space Center in Florida. They will be greeted less than 24 hours later by the seven Expedition 65 crew members residing aboard the orbiting lab.
The SpaceX Crew Dragon Endeavour sits atop the Falcon 9 rocket at the launch pad ready to carry four Commercial Crew astronauts to the space station. The SpaceX Crew-2 quartet is comprised of Commander Shane Kimbrough and Pilot Megan McArthur, both NASA astronauts, and Mission Specialists Akihiko Hoshide of the Japan Aerospace Exploration Agency (JAXA) and Thomas Pesquet of the European Space Agency.
They are set to launch on Thursday at 6:11 a.m. EDT and dock to the Harmony module’s forward-facing international docking adapter at 5:30 a.m. on Friday. NASA TV will broadcast the Crew-2 mission continuously from launch to docking beginning Thursday at 2 a.m.
There is still plenty of research and maintenance occurring on the station as NASA and SpaceX gear up for this Thursday’s launch. Walker serviced the Human Research Facility rack and updated software on the KERMIT microscope that can be operated by station astronauts or scientists on the ground. Hopkins swapped fuel canisters inside the Combustion Integrated Rack.
Vande Hei and Glover worked throughout Monday cleaning ventilation systems and crew quarters. Noguchi transferred oxygen to tanks inside the U.S. Quest airlock. Novitskiy and Dubrov, the two cosmonauts, worked on Soyuz crew ship cargo transfers and lab familiarization activities.
