Ох нифига себе...

Гав... Гав... Гавайи???  :shock:
 Это чего получается? Вывод на "почти орбитальную" траекторию с падением Центавра через 3/4 витка?

[Sharicoff]

У меня нет софта под рукой. Но скорее все же сведение Центавра через 2 неполных витка.

Да, больше похоже. Однако тогда наклонение получается какоето левое. Да и орбита тоже.

[Sharicoff]

Однако тогда наклонение получается какоето левое. Да и орбита тоже.

За наклонение пока ничего не скажу. У меня не настолько глаз-алмаз, чтобы чисто по картинке определить азимут. Скажу только, что трасса при запусках X-37B шла южнее. Т.е. по всем признакам здесь должна быть геопереходная - если бы не эта дополнительная зона в районе Гавайев. Ступени при запусках на высокие орбиты еще ни разу не топили.

Зона к юго-востоку от Канаверала никак не соответствует ГПО.

[Sharicoff]

Зона к юго-востоку от Канаверала никак не соответствует ГПО.

Именно ей она и соответствует. Почти там же была зона при запуске SBIRS GEO-1.

[Старый]

Посмотрел чуть более лиловым глазом.
Зона южнее Гавайев это почти та же траектория что и юго-восточнее Канаверала но с временнЫм сдвигом примерно на 6 часов. То есть это или сведение ступени с ЛЕО через 4-5 витков или с какойто высокой орбиты с периодом 3 или 6 часов. И то и другое странно.
 Или вариант - мужики с насаспейсфлайта чтото перепутали с долготой.

http://www.notamdecoder.com/ Солидарен с мужиками и указывает на зону, юго-западнее Гаваев.

Мужики с NSF тут не при чем - это официальное оповещение. Кстати, Молчан уже посчитал предварительные TLE: http://www.satobs.org/seesat/Jun-2012/0126.html

[Старый]

Бог с ним, ему виднее. Однако странно это - сводить ступень с ГПО.
 Значит спутник будет маленький.

June 20     Atlas 5  •  NROL-38
Launch window: 1228-1327 GMT (8:28-9:27 a.m. EDT)

[instml]

http://www.spaceflightnow.com/atlas/av023/status.html

1114 GMT (7:14 a.m. EDT)
Passing the 50 percent level on the Centaur upper stage's liquid hydrogen tank.

1110 GMT (7:10 a.m. EDT)
Centaur's liquid hydrogen tank is 20 percent full. The cryogenic propellant will be consumed with liquid oxygen by the stage's Pratt & Whitney Rocketdyne-made RL10 engine.

1105 GMT (7:05 a.m. EDT)
First stage liquid oxygen tank is 60 percent full thus far. Chilled to Minus-298 degrees F, the liquid oxygen will be used with RP-1 kerosene by the RD-180 main engine on the first stage during the initial four-and-a-quarter minutes of flight today. The 25,050 gallons of RP-1 were loaded into the rocket after rollout.

1103 GMT (7:03 a.m. EDT)
Chilldown of the liquid hydrogen system has been accomplished. The launch team has received the "go" to begin filling the Centaur upper stage with the supercold fuel.

1054 GMT (6:54 a.m. EDT)
The Centaur engine chilldown sequence is being initiated.

1050 GMT (6:50 a.m. EDT)
Centaur liquid oxygen is now at flight level.

1049 GMT (6:49 a.m. EDT)
The first stage liquid oxygen tank has reached the 20 percent mark.

1044 GMT (6:44 a.m. EDT)
The Centaur liquid oxygen tank reached the 95 percent level. The topping off process is starting now.

1043 GMT (6:43 a.m. EDT)
The first stage liquid oxygen loading is transitioning from slow-fill to fast-fill mode.

1039 GMT (6:39 a.m. EDT)
The chilldown conditioning of liquid hydrogen propellant lines at Complex 41 is starting to prepare the plumbing for transferring the Minus-423 degree F fuel into the rocket. The Centaur holds about 12,325 gallons of the cryogenic propellant.

1037 GMT (6:37 a.m. EDT)
Centaur liquid oxygen is 70 percent loaded.

1034 GMT (6:34 a.m. EDT)
The conditioning of the systems for the first stage liquid oxygen tank have been completed. And a "go" has been given to begin pumping supercold liquid oxygen into the Atlas 5's first stage.

The Common Core Booster stage's liquid oxygen tank is the largest tank to be filled today. It holds 48,745 gallons of cryogenic oxidizer for the RD-180 main engine.

1028 GMT (6:28 a.m. EDT)
Now exactly two hours until launch!

1025 GMT (6:25 a.m. EDT)
Passing the 20 percent level on the Centaur upper stage's liquid oxygen tank.

1016 GMT (6:16 a.m. EDT)
Filling of the Centaur upper stage with about 4,075 gallons of liquid oxygen has begun at Cape Canaveral's Complex 41 following the thermal conditioning of the transfer pipes.

The liquid oxygen -- chilled to Minus-298 degrees F -- will be consumed during the launch by the Centaur's single RL10 engine along with liquid hydrogen to be pumped into the stage a little later in the countdown. The Centaur will perform undisclosed number of firings to propel the payload into its intended orbit this morning.

1009 GMT (6:09 a.m. EDT)
The Centaur liquid oxygen pad storage area has been prepped. The next step is conditioning the transfer lines, which is now beginning to prepare the plumbing for flowing the cryogenic oxidizer.

1003 GMT (6:03 a.m. EDT)
T-minus 120 minutes and counting! The launch countdown has resumed on schedule for today's flight of the Atlas 5 rocket on NROL-38 mission for the National Reconnaissance Office.

Clocks have one more built-in hold planned at T-minus 4 minutes. That pause will last 25 minutes during which time the final "go" for launch will be given. All remains targeted for liftoff at 8:28 a.m. EDT from Cape Canaveral's Complex 41.

In the next couple of minutes, chilldown thermal conditioning of the mobile launch platform upon which the rocket stands will begin. This is meant to ease the shock on equipment when supercold cryogenic propellants start flowing into the rocket.

1001 GMT (6:01 a.m. EDT)
All console operators have reported GO status during the pre-fueling readiness poll. The ULA launch director also voiced his approval for moving forward with the countdown as scheduled today.

Loading of cryogenic liquid oxygen and liquid hydrogen into the Atlas 5 rocket will be getting underway a short time from now.

0958 GMT (5:58 a.m. EDT)
The ULA launch conductor at the Atlas Spaceflight Operations Center is briefing his team on procedures before entering into the final two hours of the countdown.

[Александр Ч.]

1128 GMT (7:28 a.m. EDT)
Now 60 minutes from liftoff. Fueling of the Atlas rocket with cryogenic liquid oxygen and liquid hydrogen is nearly complete as the countdown continues as planned for a liftoff at 8:28 a.m. EDT, weather permitting.

Оно уже давно идёт   , сейчас идет повтор .

[Space Alien]

1214 GMT (8:14 a.m. EDT)
The first stage liquid oxygen tank and Centaur's liquid oxygen and liquid hydrogen tanks are topped at flight level.
1212 GMT (8:12 a.m. EDT)
Upper level winds are favorable today as well.
1208 GMT (8:08 a.m. EDT)
Twenty minutes from liftoff. No reports of anything amiss technically and the weather is GO for launch at 8:28 a.m. EDT.
1203 GMT (8:03 a.m. EDT)
Atlas 5 represents the culmination of evolution stretching back several decades to America's first intercontinental ballistic missile. At the dawn of the space age, boosters named Atlas launched men into orbit during Project Mercury and became a frequent vehicle of choice to haul civil, military and commercial spacecraft to orbit.
Topped with the high-energy Centaur upper stage, Atlas rockets have been used since the 1960s to dispatch ground-breaking missions for NASA, including the Surveyors to the Moon, Mariner flights to Mars, Venus and Mercury, and the Pioneers that were the first to visit Jupiter and beyond.

In its newest era, the Atlas 5 rocket sent the Mars Reconnaissance Orbiter to the red planet in 2005, propelled the New Horizons probe toward Pluto and the solar system's outer fringes in 2006, doubled up with the dual Lunar Reconnaissance Orbiter and LCROSS impactor to the Moon in 2009, hurled Juno to Jupiter last August and dispatched the car-sized Curiosity rover on the Mars Science Lab mission in November.

Today marks the 31sth flight for Atlas 5, born of the Air Force's competition to develop next-generation Evolved Expendable Launch Vehicles. In its previous 30 missions since debuting in August 2002, the tally shows 10 flights dedicated to the Defense Department, 9 commercial missions with communications spacecraft, five with spy satellites for the National Reconnaissance Office and six for NASA.

1159 GMT (7:59 a.m. EDT)
T-minus 4 minutes and holding. The countdown has entered the planned 25-minute hold to give the launch team a chance to review all systems before pressing ahead with liftoff. The hold is longer than usual this morning, as the team built in an additional 15 minutes to the countdown to deal with any issues or catch up on work during the overnight operation.
1158 GMT (7:58 a.m. EDT)
T-minus 5 minutes. Standing by to go into the final built-in hold.

1154 GMT (7:54 a.m. EDT)
A nice gap in the cloud coverage is moving into the Cape Canaveral area now and ground winds remain below the launch limit. So all weather rules are "green" at the present time and expected to remain that way for the 8:28 a.m. EDT liftoff.
1147 GMT (7:47 a.m. EDT)
The fuel-fill sequence for the first stage main engine is starting.
1146 GMT (7:46 a.m. EDT)
Pre-launch checks of the rocket's safety system have been completed.
1143 GMT (7:43 a.m. EDT)
Today's launch is delivering to orbit a payload for the National Reconnaissance Office, the agency that operates the country's fleet of spy satellites. This is the second of four launches that the NRO has planned this year, a batch of missions that began in April with the Delta 4 from Vandenberg Air Force Base and continues with a Delta 4-Heavy next Thursday from Cape Canaveral and an Atlas 5 from Vandenberg on Aug. 2.
"Last year we executed the most aggressive launch campaign in over 25 years. We successfully launched six satellites in seven months and this year with the same determination we're scheduled to launch four more in five months," Betty Sapp, the NRO's principal deputy director, said in testimony before Congress this spring.

"These successful launches are a very important and visible reminder of the space reconnaissance mission the NRO started over 50 years ago, and continues with such great success today. We are committed to smart acquisition investments and practices to ensure the continued coverage and availability of our vital national security systems and we work tirelessly to deliver these systems on time and within budget."

Last year's remarkable launch surge used various types of Atlas and Delta rockets to launch replacement satellites into virtually all of the NRO's networks of imaging, eavesdropping, surveillance and data-relay spacecraft, plus the small Minotaur booster lofted a research and development payload.

"From launching and operating the most technically-capable systems to continued operations of legacy satellites the NRO remains the premier space reconnaissance organization in the world," said Sapp.

The identities of the satellites going up this year are not disclosed to the public. But NRO Director Bruce Carlson recently said the upcoming deployments will refresh the agency's ability to continue guarding U.S. national security.

"The launch of these systems will not only improve on the NRO's capabilities, they will also help reduce the overall age of our constellation and better deal with today's and tomorrow's global threats," he said.

1132 GMT (7:32 a.m. EDT)
The weather status board is all "green" again. The earlier "red" condition for the cloud thickness rule has passed. The outlook for today's launch window remains 60 percent favorable.
The latest forecast now calls for scattered clouds at 3,200 feet, a scattered-to-broken deck at 18,000 feet, isolated showers in the area, good visibility, easterly winds of 20 gusting to 25 knots and a temperature around 77 degrees F.
