Ariane flight VA241
Ariane flight VA241 was an Ariane 5 space launch that occurred from the Guiana Space Centre on 25 January 2018 at 22:20 UTC.
The launcher was carrying the SES-14 and Al Yah 3 geostationary satellites, with a total payload mass of approximately 9,123 kg (20,113 lb). The satellites were accommodated together on the SYLDA adapter inside the long version of the upper stage fairing.
SES-14, built by Airbus Defence and Space in Toulouse, France for SES of Luxembourg, was in the upper position. It had a mass at liftoff of 4,423 kg (9,751 lb), hosting the NASA-funded GOLD payload. SES-14 was the second satellite based on Airbus's Eurostar E3000 EOR satellite bus to be launched by Arianespace.
Al Yah 3, built by Orbital ATK in the United States for Yahsat of the United Arab Emirates, was in the lower position. It had a mass at liftoff of 3,795 kg (8,367 lb). Al Yah 3 was the first satellite based on Orbital ATK's GEOStar-3 satellite bus to be launched by Arianespace.
The 97th Ariane 5 launch (1st of 2018) was planned to take place within a launch window of 45 minutes starting on 25 January 2018 at 22:20 UTC (19:20 local time). The launcher engines effectively were ignited at the very beginning of that window, from Ariane Launch Complex No. 3 (ELA-3) in Kourou, French Guiana.
The mission was planned to last 35 minutes and 7 seconds, placing both satellites into a super-synchronous transfer orbit, with an apogee of about 45,000 km (28,000 mi) and a perigee of about 250 km (160 mi), at an inclination of about 3°.
The planned sequence was as follows:
The telemetry of the launcher was lost from about 9 minutes to 9 minutes and 30 seconds (the uncertainty being due to the fact that the data as displayed in real-time may have been extrapolated for a finite amount of time) into the flight, close to the moment when the main stage (EPC) separation and upper stage (ESC-A) ignition should have occurred.
