Space Shuttle Atlantis
Following technical issues, the launch was delayed from 2007 to 2012. In 2010, as a part of STS-132, the Space Shuttle Atlantis delivered the Mini-Research Module 1 (MRM1), Rassvet, to the station, which included a spare elbow joint with 2 limbs and the Portable Work Platform for the ERA. Further delays resulted in the ERA launch being delayed to 2014.
