Oct. 13    Atlas 5  •  DMSP F18
Launch time: approx. 1612 GMT (12:12 p.m. EDT)
Launch site: SLC-3E, Vandenberg Air Force Base, Calif.

The United Launch Alliance Atlas 5 rocket (AV-017) will launch the Defense Meteorological Satellite Program 18 spacecraft for the U.S. Air Force. Built by Lockheed Martin, this polar-orbiting weather satellite will be used by the military for global weather forecasting. The rocket will fly in the 401 vehicle configuration with a four-meter fairing, no strap-on solid rocket booster and a single-engine Centaur upper stage. Delayed from April. Moved up from July 2. Delayed from June 29, Sept. 10 and late October and Nov. 2008. Delayed again from Sept. 3. [Sept. 8]

Интересная особенность пуска: отработавший "Центавр" вместо затопления отправится на гелиоцентрическую орбиту.

А цель? Командно-измерительный комплекс погонять?

Что-то там с поведением остатков криогеники в баках...

Занятно. Нечто подобное китайцы мутили в прошлом году, при запуске FengYun-2E.

SATURDAY, OCTOBER 17, 2009
As the countdown gets underway Sunday morning, the launch team will power up the rocket and begin standard pre-flight tests to prepare the Atlas 5 rocket for its weather satellite deployment mission.

Rollback of the mobile service tower from around the rocket is scheduled to start about five hours before launch.

Crews at the pad will make preparations to systems and equipment before the site is cleared of all personnel about two hours after tower rollback.

A planned hold begins when the count reaches T-minus 120 minutes. With five minutes remaining in the hold, the team will be polled to verify all is in readiness to start fueling the rocket for launch.

Supercold liquid oxygen begins flowing into the Atlas first stage and the Centaur upper stage about two hours before launch. Liquid hydrogen fuel loading for Centaur will be completed a short time later.

A final hold is scheduled at the T-minus 4 minute mark. That will give the team a chance to finish any late work and assess the status of the rocket, payload, Range and weather before proceeding into the last moments of the countdown.

Liftoff is targeted for 9:12 a.m. local time (12:12 p.m. EDT; 1612 GMT).

The DMSP F18 launch will be the second Atlas 5 rocket flight from Vandenberg.

1757 GMT (1:57 p.m. EDT; 10:57 a.m. local)
Some post-launch comments from the Atlas and Centaur engine folks:

"Pratt & Whitney Rocketdyne congratulates United Launch Alliance on the historical milestone of 600 Atlas launches, and we are proud to have been part of the program since the first launch from Cape Canaveral Air Force Station, Fla., in 1957," said Jim Maus, director, expendable propulsion programs, Pratt & Whitney Rocketdyne.

"The AV-017 launch represents the 24th consecutive successful mission for the RD-180 engine powering an Atlas launch vehicle," said Len Dest, president and CEO of RD AMROSS.

1727 GMT (1:27 p.m. EDT; 10:27 a.m. local)
"An outstanding team effort all around. Spacelift operations are an immense technical undertaking and, once again, Vandenberg has delivered," said Col. Steven Winters, 30th Space Wing vice commander at Vandenberg Air Force Base.

"This mission is absolutely critical to the warfighter," said Winters. "Thanks to the hard work and dedication of this team, our fellow servicemembers and allies around the world can carry out their missions with the best weather data available."

1707 GMT (1:07 p.m. EDT; 10:07 a.m. local)
This launch of the DMSP satellite has the distinction of being the 600th Atlas flight dating back to 1957.

"This is a proud moment in the 52 year history of the Atlas program and for United Launch Alliance," said Mark Wilkins, ULA vice president for Atlas. "First, I want to thank our Air Force customer for trusting ULA to launch this important mission. I'd also like to recognize all the men and women who have served on the Atlas team since 1957. Their determination, dedication and attention to detail have made this significant milestone possible.

Плюс один (F18), минус один.

Russell Eberst:

94-57A, a DMSP weather satellite has undergone orbital disruption as did its predecessor 91-82A. Its orbital period has decreased, and it's now tumbling. Probably due to internal pressure compartment bursting. It will be interesting to see if numerous extra debris objects are announced. Possibly occurred on October 19.

Друзья! Подскажите, пожалуйста, есть ли в интернете реальная информация о состоянии группировки DMSP. Про NOAA и GOES найти - не проблема. Особенно про 5D-3.

Про DMSP накопал только вот:

http://saif-1.larc.nasa.gov/CEOS/db/db_missions_high_level.php?query=SORT_BY_NAME

Вроде бы, согласно сообщению выше, F12 скончался. А тут он живее всех живых.

И ещё: можно ли добыть архив новостей отсюда?

Никакого противоречия. Согласно сайту, работа с КА завершена в сентября 2004-го. В октябре 2009-го, похоже, рванули остатки гидразина.

Этому сайту? (тынц)

Т.е. в данный момент у нас работают F-14, F-16, F-16 и F-17 и F-18 на стадии ввода?

Этому сайту?

Ну да. Там же сказано, что
