NASA and Orbital Sciences announced today that the approach and berthing of the Cygnus spacecraft with the International Space Station will be further delayed until at least Saturday. This comes after yesterday's announced delay due to a data discrepancy.

Although a software fix has been developed, with Wednesday's launch and arrival of a Soyuz craft (pictured below) carrying three crew members it was decided to push back the Cygnus operation.
