Launch Scheduled- Falcon 9 Iridium 2

VANDENBERG AIR FORCE BASE, Calif. – Team Vandenberg is scheduled to launch the Iridium NEXT satellite on a SpaceX Falcon 9 rocket from Space Launch Complex-4 here Sunday, June 25, at 1:25 p.m. PDT.

This will be the first launch for Col. Michael S. Hough, 30th Space Wing commander, who took command on June 9th.

"I'm excited my first launch opportunity is in partnership with SpaceX," said Hough. "And being a part of putting Iridium NEXT in orbit to meet the growing demand for global mobile communication is icing on the cake. As a side, this will also be our first launch with the Autonomous Flight Safety System, which is expected to help decrease launch costs and improve turnaround times between launches."

The Autonomous Flight Safety System debuted on its maiden flight from Kennedy Space Center on a Falcon 9 rocket earlier this year, leveraging software developed at the 30th Space Wing.

This is the second of eight planned Iridium NEXT launches. Each launch will contribute to replacing the world’s largest commercial satellite network and the only network that covers 100 percent of the earth. Iridium NEXT will enable new capabilities like Aireon’s real-time, global aircraft surveillance and tracking service, and Iridium Certus, the Company’s next-generation communications platform that will bring broadband speeds to even the world’s most remote locations.

For questions about SpaceX, please contact John Taylor, communications director, SpaceX, at 310.363.6703 or media@spacex.com.

Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

Static Fire is June 20. Two individual launch teams, so possible to keep to the schedule, even if SpaceX launches BulgariaSat-1 the same day (based on the new back up date to the new NET 19th target).  :o

Mental error - make that 6 days later on Sunday.  Wasn't making news with a schedule change! :)

Eight hours until expected T-0 for this static fire (1:30pm local)....of course, static fires can be conducted at any time within a long window.

Knocked together an article for the Static Fire. Didn't want to repeat the "what the static fire is about", so trying to change it up each time. This one is more a round up of the near term fun:

Static Fire via L2....but as always, wait for SpaceX to tweet the confirmation of a good test via quick look review.

T-0 Forecast: The subtropical ridge will be the dominant feature on Sunday with the marine layer influence strong over the range. Cooling overnight and sustained northwesterly flow will allow the marine layer to move in over the range and linger on the coastal areas, bringing low shallow stratus and fog through the count. By T-0, the marine layer will have broken out, the stratus will be clearing out and visibility restrictions lifted. Winds will be onshore through the count with T-0 winds out of the northwest at 10 - 15 knots. Temperatures will range from 63 - 68F and max upper-level winds will be from the west at 50 knots from 34,000 to 36,000 feet. The overall POV will be 0% with no constraints of concern.

24 Hour Scrub Forecast: High pressure will continue to influence the range on Monday. The marine layer will again move in overnight, bringing low stratus and reduction to visibility through the count and a burn-off by T-0. Winds will increase slightly to 12 - 15 with knots by T-0 out of the northwest with a slightly enhanced gradient. Temperatures will rise to 65 - 70F and max upper-level winds will increase, with winds out of the west-southwest at 55 knots from 34,000 to 36,000 feet.
