Flight VS20: Soyuz with CSO-1: 24-hour delay due to weather conditions

Due to unfavorable high-altitude wind conditions above the Guiana Space Center, Arianespace's VS20 mission – initially scheduled for today, December 18 – has been postponed by 24 hours.

The Soyuz launch vehicle and its CSO-1 spacecraft payload are in a stable and safe condition.

The new targeted launch date is December 19 at exactly:

While we wait for VS20 with CSO-1 here is a nice shot of the upper composite while in S3B, for the serial number trackers, the fairing has P15000-032 and the launcher should be У15000-009 but I have no confirmation on this #VS20 #CSO #CSG #ESA

Погода благоприятна для пуска "Союза" с космодрома Куру, сообщил источник
15:16

МОСКВА, 19 дек - РИА Новости. Метеорологи дали добро на намеченный на вечер среды пуск российской ракеты-носителя "Союз-СТ" с французским разведывательным спутником CSO-1, сообщил РИА Новости источник в ракетно-космической отрасли.

"Погодные условия благоприятны для осуществления пуска сегодня в 19.37 мск", - сказал собеседник агентства.

Во вторник источник РИА Новости сообщил, что пуск ракеты "Союз-СТ" со спутником CSO-1, планировавшийся на 18 декабря, отложен на сутки из-за сильного ветра на высоте 10 километров.

Всего европейская компания Airbus Defence and Space по заказу французских военных должна изготовить спутники CSO-1 и CSO-2 для замены аппаратов аналогичного назначения Helios 2A и Helios 2B, запущенных в 2004 и 2009 годах. Полезную нагрузку для спутников производит компания Thales Alenia Space.

Спутник CSO-1 предполагается вывести на солнечно-синхронную орбиту высотой 800 километров, что позволит получать изображения земной поверхности с разрешением 35 сантиметров. Второй спутник будет также запущен ракетой "Союз-СТ" с "Фрегатом" из Французской Гвианы в 2021 году. Его планируется доставить на солнечно-синхронную орбиту высотой 480 километров для съемки с разрешением 20 сантиметров.

Russian officials, Arianespace top management and representatives from the French-run spaceport met around five hours before liftoff to authorize fueling of the three-stage Soyuz rocket with kerosene and liquid oxygen.

Managers decided to proceed with a launch attempt today after a forecast of unfavorable high-altitude winds forced officials to call off yesterday's countdown before fueling of the Soyuz rocket.

Спойлер

The launch team is loading more than 500,000 pounds of liquid oxygen and kerosene propellant into the rocket this morning, plus hydrogen peroxide to drive the engines' gas turbines and liquid nitrogen to keep the propellant tanks pressurized.

The Soyuz countdown sequence begins 5 minutes, 10 seconds prior to liftoff, then the Fregat upper stage will transition to internal power five minutes before launch.

The umbilical arm servicing the upper stage and payloads will pull away at T-minus 2 minutes, 25 seconds. The Soyuz rocket is operating on internal power at T-minus 40 seconds, and the final servicing mast retracts from the rocket 20 seconds later.

The ignition sequence of the Soyuz rocket's kerosene-fueled core stage and four strap-on boosters begins 17 seconds before liftoff, and all engines should be at full thrust three seconds before launch.

Flying for the 20th time from the Guiana Space Center in South America, the Soyuz will head north over the Atlantic with the French military's CSO 1 reconnaissance satellite, which will be released at T+plus 60 minutes, 44 seconds, into a near-circular polar orbit at an average altitude of approximately 500 miles (800 kilometers)

It will be the 11th flight of the year for Arianespace, the French launch services provider responsible for Soyuz launches from French Guiana.

The mobile gantry has now retracted into position for liftoff, revealing the Soyuz rocket on its launch pad at the Guiana Space Center.

Спойлер

The European-funded, Russian-built pad is located about eight miles northwest of the Ariane 5 and Vega launch pads at the Guiana Space Center. Engineers sel ected the Soyuz launch site based on terrain, geology and a location away from Ariane facilities to ensure they did not interfere with each other.

It took three years and cost European governments $800 million to build the Soyuz launch facility, which is known by its French acronym ELS. Other than the 17-story mobile servicing tower and four lightning masts, the launch pad is modeled after the Soyuz launch pad at the Baikonur Cosmodrome in Kazakhstan.

This morning's launch is the 20th Soyuz to fly fr om ELS.

The Soyuz pad includes blue and yellow umbilical arms and hold-down petals at the base of the rocket. On the back side of the pad is a deep flame trench dug out of granite bedrock. The facility also houses living quarters for Russian workers and a launch control center.

The Soyuz site lies closer to the town of Sinnamary than Kourou, which is more typically associated with the spaceport.
