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.

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 — Propellant loading is underway for the SpaceX Falcon 9 rocket ahead of lift off to the International Space Station for NASA’s SpaceX Crew-9 mission.

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.

Crew Access Arm Retracts

The launch director just gave a “go” for the crew access arm to retract away from SpaceX’s Dragon spacecraft and Falcon 9 rocket.

A few minutes later, Dragon’s launch escape system will be armed to allow the Crew-9 crew members to escape safely in the unlikely event of an anomaly from the moment the SpaceX Falcon 9 rocket lifts off until the Dragon spacecraft reaches orbit.

Propellant loading is coming up next.

Liftoff One Hour Away for NASA’s SpaceX Crew-9 Launch

The SpaceX closeout team has left the crew access arm, which will soon retract from the Dragon spacecraft. Launch, set for 1:17 p.m. EDT, is now less than an hour away.

Launch weather officers with the U.S. Space Force’s 45th Weather Squadron are watching lightning, rain, and wind in the area, but launch currently remains a “go” for liftoff from Space Launch Complex-40 at Cape Canaveral Space Force Station.

It will take 28.5 hours for NASA astronaut Nick Hague, commander, and Roscosmos cosmonaut Aleksandr Gorbunov, mission specialist, to reach the International Space Station and dock to the Harmony module’s forward port. Once there, they’ll be greeted by nine members of the Expedition 72 crew. There will be a brief handover 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 space station will be traveling over northeast Bulgaria during liftoff.

NASA’s SpaceX Crew-9 Mission to Perform Science Experiments

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov will be busy during their roughly five-month mission at the International Space Station.

The Crew-9 members will conduct more than 200 science investigations involving blood clotting studies, moisture effects on plants grown in space, and vision changes in astronauts.

Researchers want to determine how environmental conditions affect platelets and megakaryocytes, which are large cells found in bone marrow. Both play important roles in blood clotting and immune response, and the results could provide answers for humans in space and here on Earth.

The crew also will study the vision changes that often occur while astronauts are in orbit and if a daily vitamin B supplement will make a difference. It’s still unknown why some astronauts experience vision changes and others do not, but researchers have been studying it for years.

Members of Crew-9 will participate in a spacewalk to repair a telescope attached to the outside of the space station.

Hague and Gorbunov are scheduled to launch to the space station at 1:17 p.m. EDT aboard a SpaceX Dragon spacecraft and Falcon 9 rocket from Space Launch Complex-40 at Cape Canaveral Space Force Station in Florida.

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov are strapped in SpaceX’s Dragon spacecraft.

Hague and Gorbunov soon will go through another round of spacesuit pressurization and communication checks with NASA and SpaceX launch and mission teams.

In addition to the two crew members, the spacecraft will carry cargo, science experiments, and personal items for the five-month mission. Hague and Gorbunov will join NASA astronauts Butch Wilmore and Suni Williams, who arrived at the station in June, before returning to Earth in February 2025 as a crew of four.

Liftoff to the International Space Station remains at 1:17 p.m. EDT. At the moment of launch, the space station will be traveling over northeast Bulgaria.

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov are climbing into SpaceX’s Dragon spacecraft at Space Launch Complex-40 at Cape Canaveral Space Force Station in Florida.

Just moments ago, the pair entered the White Room and continued the tradition of signing their names on the NASA meatball logo on the wall. Hague and Gorbunov will be the first names on the wall since this is the first human spaceflight mission from Space Launch Complex-40. The White Room is an area at the end of the crew access arm that connects to the spacecraft – the term dates to the Gemini program and the white paint used on the room.

As the crew enters the Dragon spacecraft, their seats are in the upright position. Once the crew is securely inside, the seats rotate into a reclined position for launch just before launch teams close Dragon’s side hatch.

Liftoff remains at 1:17 p.m. EDT.
