1540 GMT (11:40 a.m. EDT)
 T-minus 20 minutes and counting. Although the countdown is managed by the ground-based team, the aircraft crew actually pushes the button to launch Pegasus on its journey into space.

The circuitry for the release system has been armed by the launch panel operator aboard the aircraft. Later, a switch will be flipped in the cockpit by the co-pilot. This switch, located on the right-hand portion of the center console between the captain and pilot, "enables" the release to be become active.

In the final seconds of the countdown the Orbital Sciences launch conductor on the ground will call out "drop on my mark...3, 2, 1, drop." At that point, the co-pilot will push a button next to the enable switch, releasing the Pegasus rocket and NuSTAR to fall away from the L-1011 aircraft. See a photo of the drop button taken during a tour of the L-1011.

"It takes a couple seconds and then it releases," Capt. Bill Weaver explained during a previous interview. "There is no doubt about it that the rocket has released. There is a tremendous reaction throughout the airplane. It weighs 52,000 pounds, so we experience an instantaneous weight loss of 52,000 pounds and the center of gravity shifts aft 10 percent, so the nose comes up in a pretty pronounced fashion, which is good because we like that for separation.

"We drop it at 39,000 feet and after the drop we end up eventually around 41,000, we gain a couple thousand feet altitude or separation and also we do about a 10 degree heading change to get out of the rocket exhaust.

"Five seconds after we drop it, (Pegasus) is about 500 feet below drop altitude and the first stage lights off and it pulls up. In the meantime, we have turned 10 degrees off the heading. By the time we roll out we can see it. We can hear it. When that rocket motor lights off it sounds like a freight train roaring underneath the plane. It is a pretty impressive event.

"We don't really see till we get out of the bank, then we have a really good view. We can see it all the way through first stage burn out, second stage ignition. We can't normally see the stage 3. One time we did at Vandenberg. Conditions were just right -- perfect sun, perfect atmosphere."
 
1538 GMT (11:38 a.m. EDT)
 T-minus 22 minutes and counting. The release mechanism that will drop the Pegasus rocket from the L-1011 carrier jet was just armed. This hydraulic system involves four main hooks holding the Pegasus to the aircraft as well as a nose hook. Co-pilot Ebb Harris will command the actual drop event by pushing a button in the cockpit.

Блин, какого черта время форума отличается от моего +3.00?
Старт через 12 минут вроде. Ракета под пузом. Неужели увижу хоть один старт онлайн.  :lol:

[Bizonich]

В смысле удачный, а то мне не везет, или не мне  

[dmdimon]

а что у них на одном из ракурсов на КП пусто практически?

[Bizonich]

Блин, не видно ничего и отсчет пропал

[Salo]

Улетел! :wink:

[Space Alien]

Да, улетела   .

[napalm]

И не видать ничего

1603 GMT (12:03 p.m. EDT)
 T+plus 3 minutes. The flight path, altitude and all systems are nominal aboard the Pegasus.

1603 GMT (12:03 p.m. EDT)
 T+plus 2 minutes, 40 seconds. The solid-fueled second stage has burned out. The Pegasus rocket is now in a coast period for the next few of minutes as it ascends toward the high point of its trajectory achieved by the first two stages. During this time the rocket will compute the performance of the flight thus far and adjust the third stage ignition time if necessary.

1602 GMT (12:02 p.m. EDT)
 T+plus 2 minute, 15 seconds. The two halves of the payload fairing enclosing the NuSTAR satellite on the front end of the Pegasus rocket has been jettisoned. Second stage still burning as the vehicle climbs into space.

1602 GMT (12:02 p.m. EDT)
 T+plus 1 minute, 35 seconds. STAGING. The first stage has jettisoned, allowing the Pegasus' second stage to ignite!

The first stage was 33.7 feet long, 4.2 feet in diameter, a wingspan of 22 feet and produced 163,000 pounds of thrust. The second stage is 4.2 feet long and 4.2 feet wide for 44,000 pounds of thrust.

1601 GMT (12:01 p.m. EDT)
 T+plus 1 minute, 18 seconds. The solid-propellant first stage has burned out. The vehicle is now in a ballistic coast for a few seconds before the spent stage is jettisoned and the second stage ignites.

1601 GMT (12:01 p.m. EDT)
 T+plus 1 minute. The rocket is more than 100,000 feet in altitude with a velocity now exceeding 2,500 mph.

1601 GMT (12:01 p.m. EDT)
 T+plus 40 seconds. Passing through the region of maximum aerodynamic pressure.

1601 GMT (12:01 p.m. EDT)
 T+plus 30 seconds. The Pegasus rocket is pitched up 35 degrees as it climbs on the power of its solid-fuel first stage motor at over 1,500 mph.
 
1601 GMT (12:01 p.m. EDT)
 T+plus 20 seconds. Pegasus has gone supersonic as the winged first stage propels the 55-foot-long rocket through the predawn sky.

1600:42 GMT (12:00:42 p.m. EDT)
 IGNITION of the Pegasus rocket launching NASA's NuSTAR X-ray telescope, bringing the high-energy universe into focus!

1600:37 GMT (12:00:37 p.m. EDT)
 DROP. Pegasus is away! The Orbital Sciences Pegasus XL rocket has been released from the L-1011 aircraft over the Pacific Ocean about 120 miles south of Kwajalein Atoll[/size].

 T+plus 4 minutes. No problems have been reported in today's flight.[/size]

NASA запустило орбитальную рентгеновскую обсерваторию[/size]

NASA запустило космический телескоп NuSTAR (Nuclear Spectroscopic Telescope Array). Прямую трансляцию этого события Американское космическое агентство вело в прямом эфире.

 Аппарат был запущен на ракете Pegasus с самолета Stargazer. Ракета-носитель должна вывести аппарат на расчетную геоцентрическую низкоапогейную орбиту высотой примерно 550 километров. Предполагаемое время работы аппарата составляет 2 года.

 NuSTAR представляет собой космический телескоп, который будет наблюдать за астрономическими объектами в рентгеновском диапазоне. Аппарат сконцентрируется на регистрации излучения с энергиями от 5 до 80 килоэлектровольт. Зеркало аппарата состоит из 4680 сегментов и обеспечивает беспрецедентное разрешение в диапазоне жесткого рентгеновского излучения.

 Источниками изучаемого излучения являются акреционные диски сверхмассивных черных дыр, квазары - активные центры удаленных галактик. Планируется, что данные телескопа помогут прояснить детали образования тяжелых элементов в результате взрыва сверхновых благодаря так называемому R-процессу.

 Разработка телескопа началась в 2005 году, однако в 2007-м из-за сокращения бюджета NASA на научные программы проект был заморожен. В этом же году, однако, ученые возобновили работы по миссии. Запуск аппарата неоднократно откладывался - изначально, он планировался на август 2011 года. Последней вероятной датой старта было 14 марта 2012 года.
