Не понять этих американцев - половину самолетов на восточном побережье сегодня поотменяли из-за погоды, а ракету - пускают

[Salo]

2204 GMT (6:04 p.m. EDT)
T+plus 32 minutes. Centaur systems are reported normal during this coast period.

2159 GMT (5:59 p.m. EDT)
T+plus 27 minutes. The quiet orbital coast continues. The Tracking and Data Relay Satellite system is following the vehicle and transmitting telemetry back to the launch site.

[Salo]

2208 GMT (6:08 p.m. EDT)
T+plus 36 minutes, 59 seconds. Ignition and full thrust! The Centaur has begun the firing that will send the Lunar Reconnaissance Orbiter to the Moon.

[Salo]

:wink:

[Salo]

2212 GMT (6:12 p.m. EDT)
T+plus 40 minutes. About two minutes left in this burn by the Centaur's single Pratt & Whitney Rocketdyne RL10 engine.
2211 GMT (6:11 p.m. EDT)
T+plus 39 minutes, 20 seconds. Centaur is operating correctly. Battery voltages and tank pressures are as expected. The vehicle is stable and body rates are normal.
2210 GMT (6:10 p.m. EDT)
T+plus 38 minutes. The rocket is flying over the Indian Ocean now.
2209 GMT (6:09 p.m. EDT)
T+plus 37 minutes, 30 seconds. Engine is burning well for the second time in this launch.

[Salo]

2213 GMT (6:13 p.m. EDT)
T+plus 41 minutes, 57 seconds. MECO 2. Main engine cutoff confirmed. Centaur has completed its second burn. Release of the LRO payload from the rocket is expected in about three minutes.

[Salo]

2215 GMT (6:15 p.m. EDT)
T+plus 43 minutes, 20 seconds. Centaur has hit the planned orbital parameters. itself to the proper orientation for releasing LRO.
2214 GMT (6:14 p.m. EDT)
T+plus 42 minutes, 30 seconds. Centaur is maneuvering itself to the proper orientation for releasing LRO.

Всё, говорят, сейчас отделение

[Salo]

2216 GMT (6:16 p.m. EDT)
T+plus 44 minutes, 45 seconds. SPACECRAFT SEPARATION! The Centaur upper stage has deployed the Lunar Reconnaissance Orbiter on its direct trajectory for the Moon.

The instrument-laden spacecraft is NASA's trailblazer for future human missions back the lunar surface. LRO will create detailed maps of the terrain, plot out potential landing sites, identify natural resources that could be exploited and characterize the radiation conditions that astronauts can expect.

Импульс к Луне выдан! Через две минуты разделение.

Есть разделение!

[Iva]

Ну, что?
На сегодня всё?

[byran]

Вроде еще с LRO должно прийти подтверждение о раскрытие солнечных батарей и антенн? Или уже было?

[lll]

сейчас скажут - пока старт посмотрите:)

2220 GMT (6:20 p.m. EDT)
The Lunar Reconnaissance Orbiter will reach the Moon on Tuesday morning at 5:43 a.m. EDT (0943 GMT) and ignite its engines for a nail-biting maneuver that amounts to a make-or-break moment in the $504 million mission.

The engine firing slows the spacecraft's speed and allows LRO to enter into orbit around the Moon. If all goes well, the satellite should swoop into an elliptical "commissioning orbit" of 30 by 216 kilometers (18.5 by 134 miles).

In a pre-launch interview, Craig Tooley, the LRO project manager, briefly describes what's upcoming for the spacecraft:

"We come off the launch vehicle and our very first concern is as soon as we're free and the breakwires and switches go, we begin to try to acquire commanding from the ground. We deploy the solar array, so we can get power positive. We deploy our high-gain antenna, although we have some flexibility with that because we have omni (antennas).

"We begin tracking and will do a mid-course correction to trim out whatever the Atlas gave us, and then a few days later we start doing some test burns of our larger rocket engines in preparation for this lunar orbit insertion. So basically we'll check them out so we'll know how they're actually performing before we commit to this big burn."

сказали, что должно прийти, но потом микрофон переключили

[Iva]

Всё!
Пошёл спать.
Всем спокойной ночи!

[byran]

Теоретически во время перелета они еще должны потестировать свою камеру на Земле и Луне. Т.е. первые снимки наверно появятся в ближайшие дни.

Вот и подтверждение о работоспособности LRO

2348 GMT (7:48 p.m. EDT)
The Lunar Reconnaissance Orbiter has deployed its power-generating solar array and high-speed communications antenna

My team's preparing me & themselves for my Mid Course Correction burn that will occur tomorrow.I'm loving this flight to the moon so far.:-)

Через сутки проведут первую коррекцию.
