High upper-level winds delay Ariane 5 launch
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.

While at Washburn, he was the managing editor of the student run newspaper, the Washburn Review. He also has a blog about the International Space Station, called Orbital Velocity. He met with members of the SpaceFlight Insider team during the flight of a United Launch Alliance Atlas V 551 rocket with the MUOS-4 satellite. Richardson joined our team shortly thereafter. His passion for space ignited when he watched Space Shuttle Discovery launch into space Oct. 29, 1998. Today, this fervor has accelerated toward orbit and shows no signs of slowing down. After dabbling in math and engineering courses in college, he soon realized his true calling was communicating to others about space. Since joining SpaceFlight Insider in 2015, Richardson has worked to increase the quality of our content, eventually becoming our managing editor. @TheSpaceWriter
