The launch of an Ariane 5 rocket with two U.S.-built communications satellites was scrubbed today, June 17, because of unfavorable upper-level winds. This comes after a 24-hour delay due to a problem with an umbilical connection.

“The weather is maybe the only thing we do not master, but we have to live with it,” said Stephane Israel, CEO of Arianespace, in a statement after the scrub.

Liftoff was scheduled for 4:30 p.m. EDT (20:30 GMT) at the Guiana Space Centre in French Guiana, but because the weather was not acceptable for launch, the countdown was held at the T-minus seven minute mark for an hour into the 70-minute launch window. At 5:30 p.m. EDT (21:30 GMT), the flight was officially called off.

The Arianespace team will try again tomorrow at the same time—also in a 70-minute window.

The Ariane 5 was originally scheduled to blast off last week, but launch teams had opted to delay the mission because of a problem with a cryogenic fluid connector.

When it does launch, the Ariane 5 will take EchoStar 18 and BRIsat to a geostationary transfer orbit. They will be operated by DISH Network and Indonesian-based Bank Rakyat Indonesia, respectively. Both satellites were built Space Systems Loral, a California-based company.
