A Russian Soyuz spacecraft with three passengers has successfully docked at the International Space Station. The spacecraft carrying NASA astronaut Tracy Dyson, Russian Oleg Novitsky, and Marina Vasilevskaya of Belarus arrived at the orbiting station on March 25, two days after blasting off from the Baikonur Cosmodrome in Kazakhstan. An initial launch attempt was marred by a safety alert that aborted the blastoff just 20 seconds before the countdown ended. Both Roskosmos and NASA said the crew wasn’t in danger during the aborted launch.
