NASA Crew-13 Arrives at ISS: Crew, Mission and Science Explained

NASA's SpaceX Crew-13 has officially arrived at the International Space Station where they are embarking on another long-term research mission in low Earth orbit.

The crew members are scheduled to launch into orbit aboard a SpaceX Dragon spacecraft from the Cape Canaveral Space Force Station in Florida on October 1, 2026. It arrived at the ISS later in the day and joined the Harmony module.

NASA's Crew-12 team is readying itself for a return to Earth, while Crew-13 is stepping up to their new roles.

Who Is on NASA Crew-13?

Crew-13 has 4 crew members from three space agencies:

1. Jessica Watkins — NASA astronaut and commander
2. Luke Delaney — NASA astronaut and pilot
3. Joshua Kutryk — Canadian Space Agency astronaut and mission specialist
4. Sergey Teteryatnikov — Roscosmos cosmonaut and mission specialist

Crew-13 will be Watkins' second trip to the International Space Station. She was selected as an astronaut in 2017, and has a background in geological research and related activities for NASA's Mars exploration program.

Crew-13 Launch and Docking

Dragon was launched by the Falcon 9 rocket at 11:10 a.m. ET Oct. 1 from Space Launch Complex 40.

The Dragon successfully made it into orbit and proceeded on its way to the ISS. After about eight hours in orbit, the spacecraft finally arrived at the station around 7:05 p.m. EDT at Harmony.

The seven-hour and 55-minute launch-to-docking transfer was the fastest of any U.S. spacecraft to the International Space Station, according to NASA.

Upon docking, the astronauts were greeted in the ISS where they joined the crew of Expedition 75.

Crew-13 Begins a Six-Month Mission

Crew-13 is starting a near six-month science mission on the space station, NASA says.

It will work on a number of topics relevant not only to the ISS but also to the future human explorations to the Moon and Mars.

The crew will explore health issues in humans, production of food, and technologies for longer space flights.

Human Health Research

One of the big topics is the effects of the human body in microgravity.

The crew members of SpaceX's Crew-13 mission will create human tissues in microgravity. These tissues might be used in research on personalized medicine, disease modeling and pharmaceutical testing, NASA says.

The study covers health issues like heart disease and Parkinson's disease.

The crew will also be working to understand what factors contribute to having abnormal blood flow in space.

Another experiment is a new diagnostic device for in-flight use that will help to track astronaut health.

As NASA and other space agencies launch missions that last longer than normal ISS missions, these studies are likely to become more significant.

Growing Food in Space

Crew-13's more than half mission lies in food production.

NASA is interested in learning about the ability of plants to be cultivated reliably on long-duration space missions.

Crew-13 will set up and run a largely autonomous plant growth system and raise plants in plant pillows in various locations on the station.

The study could also benefit astronauts on their future Moon or Mars explorations by allowing them to grow a portion of their food in space rather than relying on all the food that could be brought to them from Earth.

Plants may also have psychological value and play a role in future closed loop life-support systems.

Why Space Food Research Matters

It may take years, not months, to make the trip to Mars.

It would be challenging and costly to send all the food that a crew would need on Earth. Future exploration missions will thus require some food production during the mission or on another world.

The ideas can be tested relatively close to earth on board the ISS.

The ISS then still continues to be an important laboratory for technologies that might play a role in deep space missions.

Crew-13 and the ISS Crew Transition

Crew-12 was in place for the arrival of Crew-13.

This resulted in a temporary station crew of 11 on board the ISS.

The two crews then had to go through a handover period.

Overnight on October 4, Jessica Meir handed over control of the space station to Roscosmos cosmonaut Pyotr Dubrov. Meir and the rest of Crew-12 are now readying themselves for their return to Earth.

NASA is currently scheduled to undock Crew-12 on Oct. 7, subject to weather conditions.

The crew who will remain on board Expedition 75 will complete their long-duration mission, which will be referred to as Crew-13.

What Makes Crew-13 Important?

Crew-13 is not just a simple change of the guard for astronauts.

The mission embodies NASA's overall approach to exploring and developing new technologies and medical investigations on the ISS to benefit future missions to deep space.

It will offer a special facility to enable researchers to study biological processes in a weightlessness environment.

The outcomes may have medical, agricultural, space system and astronaut health applications.

The Role of SpaceX

Another NASA partnership with SpaceX is called Crew-13.

The astronauts were in SpaceX's Dragon space capsule, which was launched by a Falcon 9 rocket.

The commercial spaceflight industry provides NASA with spaceflight services via a partnership model, while NASA concentrates on research and other space exploration goals.

This has become an important component of NASA's strategy in retaining access to low Earth orbit.

What Comes Next for Crew-13?

During the next few months, Crew-13 plans to conduct its scientific investigations and keep the ISS operational.

It will aid NASA's overall efforts to prepare for human space missions beyond LEO.

As agencies pursue more ambitious missions, the study of human tissues, blood flow, human health and plant growth may all be relevant.

Crew-12's return will also help hand over responsibilities and enable the new crew to continue with the station's research program.

Final Takeaway

NASA's SpaceX Crew-13 has safely docked to the International Space Station and started a fresh science mission on the orbiting outpost.

On October 1, the four-person crew – Jessica Watkins, Luke Delaney, Joshua Kutryk and Sergey Teteryatnikov – launched and arrived on the station the same day.

Crew-13 will conduct research on human health, grow plants in microgravity and test technologies that could support human life and operation on future deep space missions over the next several months.

The mission is an opportune opportunity for NASA as it advances the knowledge and technologies it will need for extended human space missions to the Moon and eventually to Mars.
