In a replay similar to the weekend before Thanksgiving, two rockets on the opposite sides of the world are poised to launch one day after another to replenish the International Space Station with a new crew and cargo.
Three new Expedition 58 crew members are preparing to blast off to the space station on a Russian Soyuz crew ship early next week. The following day, SpaceX will launch its Dragon cargo craft to the orbital lab atop a Falcon 9 rocket.
New astronauts Anne McClain and David Saint-Jacques with veteran cosmonaut Oleg Kononenko will take a six-hour ride to the station on Monday Dec. 3. The trio will lift off inside their Soyuz MS-11 spacecraft at 6:31 a.m. EST from the Baikonur Cosmodrome in Kazakhstan. About six hours later they will reach their new home in space and dock to the Poisk module beginning a six-and-a-half-month mission.
The SpaceX Dragon is targeted to begin its ascent to space from the launch pad at the Kennedy Space Center on Dec. 4. Dragon will orbit Earth for two days loaded with new science before it is captured with the station’s Canadarm2 and installed to the Harmony module.
Back in space, three Expedition 57 crew members are getting ready for the arrival of both spacecraft while staying focused on microgravity science and spacewalk preparations.
Commander Alexander Gerst and Flight Engineer Serena Auñón-Chancellor trained for next week’s Dragon rendezvous and capture on a computer today. The duo also continued working on more life science and physics research. Gerst once again studied how protein crystals impact Parkinson’s disease to possibly improve treatments on Earth. Serena researched how cement hardens in space and continued setting up hardware for a semiconductor crystal experiment.
Cosmonaut Sergey Prokopyev is configuring the station’s Russian segment for a spacewalk targeted for Dec. 11. He and Kononenko will inspect the Soyuz MS-09 spacecraft docked to the Rassvet module before the Expedition 57 trio returns to Earth on Dec. 20.
