International Space Station (IS) is preparing for the arrival of three new crew members scheduled to begin their mission today, Wednesday, September 21. a land.

stands at its launch pad at the Baikonur Cosmodrome in Kazakhstan. The trio is scheduled to liftoff inside the Soyuz crew ship at 9:54 a.m. EDT (6:54 a.m. PDT) on Wednesday and dock to the Rassvet module less than three-and-a-half hours later. That will mark the beginning of a six-month research mission in orbit around the Earth. NASA will broadcast the launch live on NASA TV, the app, and its website, beginning at 9 a.m EDT (6 a.m PDT).

Three cosmonauts who have been living in space since March 18 are scheduled to board their Soyuz MS-21 crew ship and return to Earth just over a week later. The Soyuz vehicle, with station Commander Oleg Artemyev and Flight Engineers Denis Matveev and Sergey Korsakov inside, will undock from the Prichal module and descend through Earth’s atmosphere. Finally, it will parachute to a landing in Kazakhstan, bringing the threesome’s six-month-long orbital journey to an end. In addition to conditioning their bodies for the return to Earth’s gravity on Tuesday, the trio also spent the day packing up cargo and personal gear for stowage inside the returning Soyuz.

During the traditional Change of Command ceremony next week, ESA (European Space Agency) astronaut Samantha Cristoforetti will take over as station commander from Artemyev before he departs. The leadership change will be seen live on NASA TV, the agency’s app, and its website at 9:35 a.m. on September 28.

Research operations aboard the orbiting outpost are always ongoing whether the astronauts run the experiments themselves or scientists remotely conduct the studies from control centers on the ground. Tuesday’s space science schedule saw the astronauts busy all day exploring biology, botany, physics, and robotics.

Humans and plants are significant topics of study in space as scientists learn to sustain crews in space for longer missions and farther away from Earth. Jessica Watkins, NASA Flight Engineer, scanned her arteries with an ultrasound device and measured her blood pressure on Tuesday to understand the risks of space radiation on the cardiovascular system. Meanwhile, NASA astronaut Bob Hines planted vegetables for the soilless XROOTS botany study that explores using hydroponic and aeroponic techniques to grow crops in space.

Technology is also key to the success of crewed missions. This would allow astronauts to focus more on science activities and become less reliant on ground controllers. Kjell Lindgren, NASA Flight Engineer, looked at how weightlessness affects the microstructures of foam through the KERMIT microscope to advance research and commercial opportunities on Earth and in space. Finally, ESA astronaut Samantha Cristoforetti tested using a smartphone device to guide and control Astrobee robotic free-flyers while assisting crews with scientific operations.
