Launch Weather Officer Capt. Addison Nichols confirms all conditions remain acceptable for liftoff less than 30 minutes from now. Although the earlier forecasts called for unrestricted visibility, the fog has moved in. Live reports from Vandenberg: http://bit.ly/av_landsat9

Туман полёту - не помеха.

The Centaur continues firing to obtain orbital velocity, burning liquid hydrogen and liquid oxygen propellants, and the telemetry of system status looks good. http://bit.ly/av_landsat9

Пишут - норм!

[Blackhavvk]

Вроде все ок, слава богу. Но удивительно конечно, не очень понимаю, надо глянуть как работает Атлас.

This first burn of the Centaur upper stage in today's launch will deliver the Landsat 9 spacecraft into its targeted orbit, inclined 98.2 degrees to the equator. http://bit.ly/av_landsat9

Да это ладно, но что насчет телеметрии?

The first main engine cutoff, or MECO-1, is confirmed for the #AtlasV rocket's Centaur upper stage. The vehicle has reached a sun-synchronous orbit Earth orbit for release of Landsat 9. http://bit.ly/av_landsat9

Движок отработал. ожидают отделение.

[zandr]

Нет.

ULA  @ulalaunch
We're now beginning an hour-long coast around the world to the other side of the globe to release #Landsat9 while emerging from the Earth's shadow to begin the daylight portion of the orbital pass. Deployment of the observatory will occur at T+plus 1 hour, 20 minutes.

Отделение - через час, в зоне видимости.

  SciNews
A United Launch Alliance (ULA) Atlas V 401 launch vehicle launched the Landsat 9 Earth-observation satellite into a near-polar, sun-synchronous orbit, from Space Launch Complex-3 at Vandenberg Space Force Base, California, on 27 September 2021, at 18:12 UTC (11:12 PDT). Landsat 9 is a joint mission of NASA and the U.S. Geological Survey (USGS) and will join Landsat 8 in orbit, collecting images from across the Earth every eight days.

Here's another view of the Atlas 5 rocket climbing off the SLC-3E launch pad at foggy Vandenberg Space Force Base to begin the Landsat 9 mission.
The Atlas 5's RD-180 engine generated 860,000 pounds of thrust at full throttle.
