The launch of an Atlas V 541 rocket carrying the USSF-12 mission for the U.S. Space Force's Space Systems Command (SSC) has been delayed due to weather impacting launch processing milestones. Launch is now planned for June 30. The launch window will be released closer to launch.

The countdown has resumed, and we are GO to fuel the #AtlasV rocket with 66,000 gallons of liquid oxygen and liquid hydrogen. ULA Launch Director James Whelan has authorized cryogenic tanking operations. Liftoff remains targeted for 6:00pmEDT (2200 UTC). http://bit.ly/av_ussf12

Fueling operations have been initiated at the Space Launch Complex-41 pad. The first step in tanking procedures is loading 4,150 gallons of liquid oxygen into the Centaur upper stage for today's launch of the #USSF12 mission. http://bit.ly/av_ussf12

A check of the current weather conditions is GO across the board. No weather rules are being violated at this time. The forecast for the #USSF12 launch window has improved to 60 percent favorable for the entire two-hour opportunity.
Погода 60% для всего двухчасового окна.

Согласно официальному прогнозу запуска, опубликованному 45-й метеорологической эскадрильей космических сил, вероятность благоприятной погоды на момент открытия окна в четверг составляет 40%. Прогноз улучшается позже в окне, когда вероятность благоприятных условий для запуска составляет 60%.

Миссия, известная как USSF 12, запустит на геостационарную орбиту спутник Wide Field of View Testbed Космических сил США и космический корабль USSF 12 Ring.
Космический корабль WFOV отправится в космос в верхней части отсека полезной нагрузки ракеты Atlas 5. Вторичная полезная нагрузка, называемая USSF 12 Ring,  расположена под космическим кораблем WFOV для запуска. На нем размещается множество полезных нагрузок, экспериментов и прототипов, но подробности об их миссиях засекречены.

Это один из 23 Atlas 5, оставшихся на вооружении ULA до того, как ракета будет списана.

Weather has gone red due to a storm cell just north of the launch site. Meteorologists continually monitor the weather conditions against the launch rules. That is reported as rules go red and green.
