A few hours ago the spacecraft Soyuz TMA- 12M, which lifted off a little over two days ago from the Baikonur Cosmodrome in Kazakhstan, has reached the International Space Station carrying three new crew members. The Soyuz was expected to use the fast trajectory regularly used but a sheduled thruster burn didn’t occur and that didn’t allow the spaceship to take the correct route. It was no longer possible to make a course correction so the Soyuz used the backup trajectory, normally used until a couple of years ago, which requires about two days of travel.
