The astronauts of SpaceX's Crew-11 mission are making their final preparations for their July 31 trip to the International Space Station (ISS).

The four-person crew will lift off from NASA's Kennedy Space Center in Florida, riding in the Crew Dragon Endeavour spacecraft atop a SpaceX Falcon 9 rocket on July 31, if all goes according to plan. This will be the sixth time that Endeavour has launched to space, making it SpaceX's most-flown Crew Dragon ever.

But two of the spaceflyers on board, NASA astronaut Zena Cardman and Oleg Platonov of Russia's space agency Roscosmos, aren't as seasoned; Crew-11 will be their first flight. The other two, NASA's Mike Fincke and Kimiya Yui from the Japan Aerospace Exploration Agency (JAXA), will be making their fourth and second flight to space, respectively.

If all goes according to plan, Crew-11 will dock at the ISS on Saturday, Aug. 2. Docking is targeted for 3 a.m. ET (0800 GMT), and hatch opening and a welcome ceremony should follow some two hours later.

Crew-11 will spend six months aboard the ISS conducting scientific experiments and routine space station operations. The four Crew-11 astronauts will be relieving the Crew-10 quartet, who will return to Earth a few days later.
