France-based satellite launch service Arianespace has delayed flight 158 again, this time by several days due to a minor anomaly observed on the thermal protection of the main cryogenic stage (EPC).

The launch-services provider postponed the mission Thursday due to high winds aloft but that hold was only for a single day. Because corrective action is required, the launch vehicle will be rolled back to the final assembly building for the necessary repair work. The Rosetta spacecraft remains inside the rocket’s fairing.

The countdown is expected to resume early next week.
