Citing medical reasons, Russia’s space agency announced Wednesday that it is replacing two cosmonauts who were scheduled to fly on the next Soyuz mission to the International Space Station in April with backup crew members.

Russian commander Anton Shkaplerov, NASA flight engineer Scott Tingle and Japanese astronaut Norishige Kanai docked with the International Space Station Tuesday at 3:39 a.m. EST (0839 GMT), two days after blastoff from the Baikonur Cosmodrome in Kazakhstan.
