NASA's Crew-13 Lifts Off: SpaceX Launches 4 Astronauts To Study Disease And Crops For Moon, Mars

NASA's Crew-13 mission launched aboard SpaceX to the International Space Station with four astronauts to study disease, crop growth and health research to prepare for future Moon and Mars exploration missions.

Florida: A new team is now racing towards the International Space Station (ISS) after clearing one of the trickiest countdowns of the year. NASA and SpaceX have successfully launched Crew-13 from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida on Thursday. Four astronauts are on board the Dragon spacecraft named Grace.

The SpaceX Falcon 9 lifted off at about 8.40 pm with NASA astronauts Jessica Watkins and Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov.

The crew-13 registers the 13th crew rotation mission flown by SpaceX's human transportation system and the 14th crewed flight to the orbiting laboratory under NASA's Commercial Crew Programme, counting the Demo-2 test flight. Watkins has taken the role of commander, with Delaney serving as pilot, while Kutryk and Teteryatnikov are flying as mission specialists.

As it is said, the flight is a milestone for Watkins, as it is her second spaceflight and her second journey aboard a SpaceX Dragon, making her the first NASA astronaut set to fly aboard a Dragon spacecraft twice. While the flight is their first trip to space for her three crewmates, Delaney, Kutryk and Teteryatnikov.

The team is travelling in Dragon Grace, a capsule with heritage, as it previously visited the ISS during Axiom Mission 4 in 2025. The Falcon 9 first stage supporting this launch is also reused and is now making its third flight.

The mission had faced a hold-up earlier, with a leak detected in Dragon's propulsion system, forcing a delay. SpaceX engineers replaced the affected component before NASA and its international partners gave the go-ahead for launch.

Weather remained the biggest uncertainty in the final hours before liftoff. The US Space Force's 45th Weather Squadron had assessed the chance of favourable conditions at 55% on September 30, but that figure was reduced to 40% on launch day.

The main concerns flagged were the cumulus cloud rule, thick cloud layers and the risk of the rocket flying through precipitation. The moist air and scattered showers were drifting across Florida, which made it difficult to pin down exactly where and when cloud and rain would develop.

NASA nevertheless pressed ahead with the countdown, as at the time of launch, the team was working with an expectation of a 60% chance of favourable conditions, and succeeded in sending the new crew on the way to the ISS.

Once in orbit, Dragon will carry out a series of manoeuvres to catch up with the ISS before starting the final approach. The spacecraft is designed to dock autonomously, although the crew can take manual control if necessary.

Dragon is scheduled to dock at the forward-facing port of the station's Harmony module at around 4:30 am on Friday. The planned journey from liftoff to docking is about 7 hours and 50 minutes, which NASA said would make Crew-13 the fastest launch-to-docking journey by a US spacecraft to the ISS.

After docking and hatch opening, the 4 astronauts will join the Expedition 75 crew aboard the station. They are expected to spend around 6 months conducting scientific experiments, technology demonstrations and maintenance work, including research aimed at improving human health and preparing for future missions to the Moon and Mars. The crew-13 is currently scheduled to return to Earth in 2027.
