SES-5, EchoStar 17 To Launch Despite Intelsat-19 Mishap

In both cases, Sea Launch and Space Systems/Loral detected an out-of-boundary pressure event some 72 sec. after liftoff. And, in both cases, the satellite was released with a solar array panel that refused to deploy.
Last week Bern, Switzerland-based Sea Launch released preliminary “quick look” telemetry data, saying its rocket performed nominally during launch all the way through separation of the payload fairing and satellite release. But it will take at least several days, if not more, to fully analyze all the telemetry available to Sea Launch.
In the meantime, the clock is ticking for EchoStar, SES, ILS, Arianespace and Space Systems/Loral, not to mention the satellite operators' insurers, who have hundreds of millions of dollars riding on the SES-5 and EchoStar 17 satellites.
On June 11, Arianespace said it had rescheduled liftoff of MSG-3 and EchoStar 17 to July 5 from June 19 to give Hughes/EchoStar time to conduct additional checks of the Ka-band satellite. The following day, ILS said it would go ahead with a June 20 launch of SES-5 by a Proton-M/Breeze-M rocket from the Baikonur Cosmodrome in Kazakhstan. But it is entirely possible that no definitive answers about what happened to Intelsat-19 will be available before these launch dates.
