Stormy weather in Florida delays Falcon 9 launch

SpaceX has delayed a planned Falcon 9 launch with a Japanese communications satellite to Friday due to inclement weather on Florida’s Space Coast.

The launch window is unchanged, opening at 1:21 a.m. EDT (0521 GMT) and extending for two hours Friday, to put the JCSAT 14 commercial communications satellite into orbit for SKY Perfect JSAT Corp. of Tokyo.

The 229-foot-tall rocket could have been exposed to storms streaming over Central Florida on Wednesday if SpaceX went ahead with a launch attempt Thursday morning.

The Falcon 9 will blast off from Cape Canaveral’s seaside Complex 40 launch pad.

There is a 90 percent chance of favorable weather during Friday’s launch window, according to the official U.S. Air Force forecast. The only concern is with residual moisture over Cape Canaveral that could generate clouds, violating the thick cloud rule.

The launch will mark the Falcon 9’s fourth flight of the year, and the rocket’s 24th launch since its debut in June 2010.

Intense thunderstorms over Florida prevented the Falcon 9 from launching Thursday.

The rocket’s second stage will ignite two times before deploying the JCSAT 14 spacecraft in geostationary transfer orbit about 32 minutes after liftoff.

SpaceX hopes to recover the Falcon 9’s first stage on a landing platform in the Atlantic Ocean east of Cape Canaveral, but the company says the recovery attempt is unlikely to succeed due to the high speed required to put the JCSAT 14 satellite into its high-altitude orbit.

“Following stage separation, the first stage of Falcon 9 will attempt an experimental landing on the ‘Of Course I Still Love You’ droneship,” SpaceX said in a post on the company’s website. “Given this mission’s GTO destination, the first-stage will be subject to extreme velocities and re-entry heating, making a successful landing unlikely.”

The landing experiment will further test out SpaceX’s plan for recovering and reusing Falcon 9 first stage boosters.

The JCSAT 14 communications satellite, made by Space Systems/Loral, is kicking off a 15-year mission providing television broadcast, data network and broadband Internet services over the Asia-Pacific.

It will extend and replace coverage currently offered by the JCSAT 2A spacecraft launched in 2002 by a European Ariane 4 rocket. The new craft will be renamed JCSAT 2B once it is operational.

Four satellites for SKY Perfect JSAT have launched from Cape Canaveral before JCSAT 14.

The JCSAT 2 communications satellite flew into space aboard a commercial Titan 3 rocket on New Year’s Eve 1989. Lockheed Martin Atlas 2AS rockets took off with three more JCSAT telecom birds in 1995, 1997 and 1999.

JCSAT 14 is the first satellite SKY Perfect JSAT has contracted to launch with SpaceX.

The Japanese telecom company has two more satellites in final assembly for launches later this year — one aboard a European Ariane 5 rocket and another on Falcon 9.
