0007 GMT (7:07 p.m. EST Sat.)
 T+plus 25 minutes, 40 seconds. About two minutes are left in the burn to reach the next orbit. Everything continues to look nominal.
 
0005 GMT (7:05 p.m. EST Sat.)
 T+plus 23 minutes. Continued good engine operation is being delivered by the RL10C, no problems reported.
 
0004 GMT (7:04 p.m. EST Sat.)
 T+plus 22 minutes, 45 seconds. The engine is burning well. This is a planned five-and-a-half-minute firing by the Centaur's single Aerojet Rocketdyne RL10C engine.
 
0004 GMT (7:04 p.m. EST Sat.)
 T+plus 22 minutes, 6 seconds. Ignition! The Centaur's single RL10C engine has re-ignited to climb into a highly elliptical intermediate orbit on the way to the final perch later today.
 
0003 GMT (7:03 p.m. EST Sat.)
 T+plus 21 minutes, 56 seconds. Liquid hydrogen and liquid oxygen system prestarts are underway.
 
0003 GMT (7:03 p.m. EST Sat.)
 T+plus 21 minutes. Centaur getting into its pressurization sequence.
 
0002 GMT (7:02 p.m. EST Sat.)
 T+plus 20 minutes. Velocity currently 17,692 mph.
 
0001 GMT (7:01 p.m. EST Sat.)
 T+plus 19 minutes. The flight path is taking the vehicle over the equatorial Atlantic Ocean, soon to near the western coast of Africa where the next Centaur burn will occur. It will soar away from the Indian Ocean over the course of the next couple of hours before the RL10C restarts for a final time to accelerate GOES-R into the geosynchronous transfer orbit and separating the payload.
 
0000 GMT (7:00 p.m. EST Sat.)
 T+plus 18 minutes. Centaur is half-way through this coast period. It is completing a slow roll to keep thermal heating even across the rocket's surfaces.

0019 GMT (7:19 p.m. EST Sat.)
 T+plus 37 minutes, Current velocity is 20,284 mph.
 
0014 GMT (7:14 p.m. EST Sat.)
 We will pause our live updates at this time. Check back around 10:09 p.m. EST for coverage of the third Centaur burn and deploy of the GOES-R satellite to complete today's mission.
 
0012 GMT (7:12 p.m. EST Sat.)
 T+plus 30 minutes. Centaur now begins a quiet three-hour coast through space, moving higher and away from the planet before the third and final burn occurs three hours and 27 minutes into flight. Deployment of GOES-R from the rocket to complete the launch is expected 3 hours, 32 minutes after launch.
 
0011 GMT (7:11 p.m. EST Sat.)
 T+plus 29 minutes, 30 seconds. The second burn by Centaur ins erted the rocket in to another precise orbit as targeted.
 
0009 GMT (7:09 p.m. EST Sat.)
 T+plus 27 minutes, 40 seconds. MECO 2. Main engine cutoff confirmed. Centaur has completed its second burn of the day, this one taking the next step upwards to substantially increase the altitude from the previous parking to nearly geosynchronous height.
 
0008 GMT (7:08 p.m. EST Sat.)
 T+plus 26 minutes, 45 seconds. Engine performance remains normal.

GOES –R, the first spacecraft in a new series of NASA-built advanced geostationary weather satellites, separated from the United Launch Alliance Atlas V rocket it was launched aboard Nov. 19, from Cape Canaveral Air Force Station in Florida. Once in geostationary orbit, GOES-R will be known as GOES-16 and will provide images of weather patterns and severe storms as regularly as every five minutes or as frequently as every 30 seconds. These images can be used to aid in weather forecasts, severe weather outlooks, watches and warnings, lightning conditions, maritime forecasts and aviation forecasts.

GOES-R will become GOES-16 once operational. Mass is 2857 kg plus additional 2335 kg of propellant for its onboard engine
 
  Jonathan McDowell ‏@planet4589 4 ч.4 часа назад
GOES stands for Geostationary Operational Environmental Satellite. GOES 1 was launched in 1975, the prototype SMS 1 in 1974
 
  Jonathan McDowell ‏@planet4589 4 ч.4 часа назад
GOES-R has now separated from Centaur AV-069, both objects in high-perigee geotransfer orbit. Congrats to @NOAASatellites @ulalaunch
 
  Jonathan McDowell ‏@planet4589 4 ч.4 часа назад
Correction: Centaur MECO-3, orbit now 8141 x 35288 km x 10.6 deg Preparing to separate the GOES-R satellite (corrected typo in apogee)

  Jonathan McDowell ‏@planet4589 .4 ч.4 часа назад
This burn increasing speed at apogee will make the perigee higher, reducing how much fuel the sat itself needs to get to GEO
 
  Jonathan McDowell ‏@planet4589 4 ч.4 часа назад
Centaur third burn (MES-3, Main Engine Start 3) underway
 
  Jonathan McDowell ‏@planet4589 4 ч.4 часа назад
Centaur approaching apogee; third burn in 15 min at 0309 UTC

Steve Volz, NOAA Assistant Administrator for Satellites and Information Services (NESDIS) lauded the satellite's capabilities at a press conference today, saying they are a "quantum leap" beyond the GOES satellites currently on orbit -- GOES-13, -14 and -15.   He likened it to the difference between black and white television of yesteryear and ultra high definition television of today.
...
GOES-R has six instruments.  Mandt explained that the spacecraft's primary instrument, the Advanced Baseline Imager (ABI), will have three times the spectral resolution of its predecessors and will be able to scan from the North to South poles 5 times faster.  It will be able to zoom in on a specific storm and look at it every 30 seconds -- a temporal resolution that will "revolutionize forecasting."  

Japan's Himawari 8, already in orbit, has an ABI, enabling NOAA to test out new algorithms before GOES-R is launched, he added.

GOES-R also has a lightning mapper that will allow tracking cloud-to-cloud lightning in addition to cloud-to-ground, and lightning over oceans.  Another instrument will be able to spot not only when fog is forming, but when it is decaying, which will improve airport operations, for example. Space weather instruments also are aboard to study activity on the Sun that can affect the Earth.

Louis Uccellini, Director of NOAA's National Weather Service, enthused that the GOES-R will provide "new and improved forecasts and warnings from the Sun to the sea to help save lives and property."

will be able to scan from the North to South poles

С геостационара сканировать полюса это действительно революционное нововведение, эквивалентное изобретению кривых лучей света.  

В остальном не понял. Ну будет сканировать в разы быстрее, с в разы лучшим спектральным и пространственным разрешением. Как это приведёт к революции в метеорологии? Чай не разведка...

Надо чтобы Фалькон-9 запустил аналогичный аппарат и тогда мы узнаем от Валерия, почему это должно столько стоить и почему "столько стоит" запускают именно на Фальконах-9, а не на какой либо другой ракет в мире

Не разведка. В метеорологии всё гораздо быстрее меняется и зачастую дороже по последствиям.

Предыдущие спутники меняли картинку кажется раз в 10-15 минут. Неужели с тех пор в метеорологии всё настолько убыстрилось?

Теперь ураганы будут отслеживаться каждые 30 секунд. Думаешь просто прикалываются?

Да хоть в 30 милисекунд. Какую революцию то это вызовет?
