Sunday’s launch is the latest to take place for NASA, which after a series of budget cuts retired its shuttle fleet earlier this year. Since then it has had to rely on the Soviet-era Soyuz as governments and private companies scramble for new ways to launch humans to the station and beyond.
In a statement released from NASA headquarters, officials said the mission is likely to remain on track and should go smoothly.
Ironically, today's launch took place on the 37th anniversary of the landmark Apollo-Soyuz mission.
