The seven astronauts and four cosmonauts representing the Expedition 72 crew slept in on Monday working half-a-day during the afternoon following Sunday’s arrival of the SpaceX Crew-9 mission.

The International Space Station’s two newest crew members, Nick Hague of NASA and Aleksandr Gorbunov of Roscosmos, launched to the orbital outpost aboard the SpaceX Dragon at 1:17 p.m. EDT on Saturday. The duo docked to the Harmony module’s forward port at 5:30 p.m. on Sunday beginning a five-month space research mission.

Hague, on his second spaceflight, began his day on Monday afternoon joining NASA Flight Engineer Jeanette Epps as she demonstrated how to operate the advanced resistive exercise device to maintain muscle and bone mass in weightlessness. Afterward, he joined NASA Flight Engineer Matthew Dominick and transferred standard emergency gear inside the newly arrived Dragon spacecraft.

Gorbunov kicked off his first full day on the orbital lab getting familiar with life on the space station and learning its systems and procedures. Next, he joined fellow cosmonaut Alexander Grebenkin who began handing over his mission responsibilities to Gorbunov.

Flight Engineers Mike Barratt and Butch Wilmore with Commander Suni Williams, all three from NASA, helped unpack cargo and fresh scientific samples from Dragon. The trio removed and stowed a variety of crew supplies and station hardware then transferred portable science freezers containing the research samples and installed them inside station science freezers for preservation and later analysis.

Having been aboard the space station since Sept. 11, NASA Flight Engineer Don Pettit spent his shift on orbital plumbing duties, analyzing station water for microbes, and configuring specialized watches that monitor a crew member’s sleep/wake cycle. His Soyuz MS-26 crewmates, Flight Engineers Alexey Ovchinin and Ivan Vagner, spent the day servicing electronics systems and Earth observation hardware.

The next crew to depart the orbital outpost, SpaceX Crew-8, has been stepping up its cargo packing duties and mission handover responsibilities the last several days. NASA and SpaceX are evaluating departure opportunities before Dominick leads Barratt, Epps and Grebenkin back to Earth inside Dragon ending a six-and-a-half-month mission orbiting Earth.

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov arrived at the International Space Station Sunday, as the SpaceX Dragon Freedom docked to the orbiting complex at 5:30 p.m. EDT while the station was 260 statute miles over Botswana.

Following Dragon’s link up to the Harmony module, the astronauts aboard the Dragon and the space station will begin conducting standard leak checks and pressurization between the spacecraft in preparation for hatch opening scheduled for approximately 7:15 p.m.

Hague and Gorbunov will join the space station’s Expedition 72 crew of NASA astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, Don Petitt, Butch Wilmore, and Suni Williams, as well as Roscosmos cosmonauts Alexander Grebenkin, Alexey Ovchinin, and Ivan Vagner. For a short time, the number of crew aboard the space station will increase to 11 people until Crew-8 members Dominick, Barratt, Epps, and Grebenkin return to Earth in early October.

NASA+, YouTube, and the agency’s website are continuing to provide live coverage of the agency’s SpaceX Crew-9 mission carrying NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov to the International Space Station.

The SpaceX Dragon spacecraft is scheduled to dock about 5:30 p.m. EDT, Sunday, Sept. 29. Dragon is designed to dock autonomously, but the crew aboard the spacecraft and the space station will monitor the performance of the spacecraft as it approaches and docks to the forward port of the station’s Harmony module.

When the hatches open at about one hour and 45 minutes after docking, the Crew-9 astronauts will join the Expedition 72 crew of NASA astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, Don Petitt, Butch Wilmore, and Suni Williams, as well as Roscosmos cosmonauts Alexander Grebenkin, Alexey Ovchinin, and Ivan Vagner.

At 1:29 EDT, SpaceX’s Dragon spacecraft separated from the Falcon 9 rocket second stage and now is flying on its own.  

NASA astronaut Nick Hague, commander, and Roscosmos cosmonaut Aleksandr Gorbunov, mission specialist, are on a 28.5-hour journey to the International Space Station. The spacecraft now is in orbit and will autonomously dock to the Harmony module’s forward port. Soon, the crew will open their visors and get out of their suits during the ride.  

Once Hague and Gorbunov reach the orbiting laboratory, they will be greeted by nine members of the Expedition 72 crew. There will be a brief overlap period before NASA’s SpaceX Crew-8 members, NASA astronauts Matthew Dominick, Mike Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin return to Earth. The four-person crew has been at the orbiting laboratory since March 5, when they docked to the orbital outpost aboard the SpaceX Dragon Endeavour spacecraft.

The first stage of the SpaceX Falcon 9 rocket has completed its descent and landed at the company’s Landing Zone 1 at Cape Canaveral Space Force Station in Florida. 

Next, the Dragon spacecraft will separate from the rocket’s second stage to continue its journey to the International Space Station. 

Falcon 9 Max Q, Main Engine Cutoff, Stage Separation

SpaceX’s Falcon 9 rocket has reached Max-Q, the moment of peak mechanical stress on the rocket. Following this, first stage main engine cutoff occurred, and the first and second stages have separated from each other.  

The rocket’s first stage booster is scheduled to land at SpaceX’s Landing Zone 1 at Cape Canaveral Space Force Station in Florida.  

Next, the Falcon 9’s second-stage engine will ignite to carry Crew-9 and the Dragon spacecraft closer to orbit.  

Liftoff! NASA’s SpaceX Crew-9 Heads to Space Station

NASA’s SpaceX Crew-9 mission lifted off at 1:17 p.m. EDT from Space Launch Complex-40 at Cape Canaveral Space Force Station in Florida. This marks the first time a human spaceflight mission launched from the pad.  

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov are already experiencing 2 g while SpaceX’s Dragon spacecraft and Falcon 9 rocket go through a rapid succession of events.   

It is expected to take 28.5 hours for the spacecraft to autonomously dock to the space station at 5:30 p.m. EDT Sunday, Sept. 29, while traveling 17,000 mph orbiting the Earth.  

Coming up next, the nine Merlin engines on Falcon 9’s first stage will burn through one million pounds of propellant during the next three minutes.  

NASA’s live coverage continues on NASA+ and the agency’s website. Also, check back for updates on the mission blog, @commercial_crew on X, or commercial crew on Facebook. 

Propellant and Liquid Oxygen Loading Begins

The SpaceX launch director polled NASA and SpaceX managers in Hangar X at the agency’s Kennedy Space Center in Florida and gave a 'go’ for fueling for the Falcon 9 rocket and Dragon spacecraft that will carry NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov for a science expedition mission aboard the International Space

The SpaceX Falcon 9 rocket fueling is underway with rocket-grade kerosene (RP-1) and first-stage liquid oxygen. About 16 minutes before liftoff, liquid oxygen fueling will begin for the second stage.   

Liftoff is the next big milestone! Launch weather officers with the U.S. Space Force 45th Weather Squadron predict a 70% chance of favorable weather conditions for launch.   

Liftoff remains scheduled for 1:17 p.m. EDT from Space Launch Complex-40 at Cape Canaveral Space Force Station in Florida.
