Final Ariane 5 launch delayed due to technical issue.

Arianespace has postponed the final launch of the Ariane 5 rocket due to a potential problem with pyrotechnical systems. The company discovered a "nonconformance" in pyrotechnical transmission lines during acceptance testing for another program. The launch was carrying two government communications satellites and was scheduled for June 16 from Kourou, French Guiana. Arianespace has not set a new launch date for the mission, which marks the retirement of the Ariane 5.
