MOSCOW—A Russian Soyuz spacecraft carrying three new crew docked at the International Space Station today after a safe but unusually long two-day flight.
The arrival of Russia’s Sergei Volkov, Denmark’s Andreas Mogensen, and Kazakhstan’s Aidyn Aimbetov brings the number of astronauts on the orbiting space outpost to nine for the first time since November, 2013.
Mogensen, the first Dane in space, got a message from his mother shortly after he arrived.
“I am really looking to have you back on Earth again,” Lisa Bjerregaard said during a video link from Baikonur, the cosmodrome in Kazakhstan where the spacecraft was launched Wednesday with relatives in attendance.
“Don’t forget to call me when you land.”
Mogensen answered: “Yeah, yeah, I promise.”
The exchange was shown live on television in Denmark.
Mogensen and Aimbetov will return to Earth on Sept. 12 along with Russian Gennady Padalka, the current station commander.
Command then will be passed to NASA’s Scott Kelly, who along with Mikhail Kornienko of Russia is spending a full year on the station to study the effects of long space travel in preparation for a possible future trip to Mars.
Russian Mission Control said the Soyuz docked on time at 10:42 a.m. Moscow time—about 51 hours after blasting off from Baikonur, the launch complex operated by Russia.
For the past two years, the space station crews have taken a more direct, six-hour flight to the station.
This time, however, the Russian Federal Space Agency decided to revert to the traditional route, citing security concerns after the space station had to adjust its orbit to dodge space junk.
