Arianespace delayed the launch of a Vega rocket from French Guiana Tuesday night due to a typhoon threatening a ground station in South Korea needed to track the vehicle as it deploys a cluster of more than 50 small satellites.

After an unusual stretch of excessive high-altitude winds prevented launch from French Guiana of 53 small satellites on a Vega rocket in June — and no sign of a letup in winds in the coming days — Arianespace said Wednesday that the mission will be delayed to Aug. 17 to allow time for teams to recharge launcher and payload batteries.

Debuting a two-tier structure designed to accommodate dozens of small satellites on a single mission, an Italian-made Vega rocket is set for liftoff Saturday night from the northeastern coast of South America on a flight to demonstrate European industry’s answer to growing rideshare launch demand.

The first launch of an Italian-made Vega rocket since an in-flight failure nearly one year ago has been postponed to no earlier than Monday night due to unfavorable upper level winds over the Vega launch base in Kourou, French Guiana.
