By March 2013, the launch was scheduled by NASA for no earlier than 28 November 2013, with berthing to the station occurring three days later on 1 December 2013 [REF].
On 12 March 2014 the launch was rescheduled to 30 March or 2 April 2014, for a variety of reasons including data buffering issues, working some issues with the range, some operational issues with the new Dragon design, and some contamination of the impact shielding blanket.
