Ariane Flight VA245[1][2] is the Ariane 5 space launch of BepiColombo that took place on 20 October 2018 at 01:45:28Шаблон:NbspUTC from the Guiana Space Centre. It was the Шаблон:Ordinal launch of Ariane 5 (the Шаблон:Ordinal in 2018), and the Шаблон:Ordinal Arianespace mission (the Шаблон:Ordinal in 2018).
Payload
The payload of the launcher was the BepiColombo spacecraft. The total payload mass was approximately Шаблон:Convert, including the payload adapter.
BepiColombo
Шаблон:Main BepiColombo had a liftoff mass of approximately Шаблон:Convert. It comprises 3 different elements that will remain attached together during launch and cruise to Mercury: the Mercury Transfer Module (MTM), the Mercury Planetary Orbiter (MPO), and the Mercury Magnetospheric Orbiter (Mio or MMO). The assembly was accommodated inside the long version of the upper stage fairing.[1] BepiColombo, a joint mission between ESA and JAXA, is Europe's first space mission to Mercury. The European modules (MTM and MPO) were designed and manufactured by Airbus at its Friedrichshafen site in Germany as prime contractor for ESA, heading a consortium of 83 companies from 16 countries.[3] The Japanese module (Mio) was built by ISAS for JAXA.[1] This flight was Airbus's Шаблон:Ordinal mission, ESA's Шаблон:Ordinal mission and Шаблон:Ordinal spacecraft launched by Arianespace, and the latter's Шаблон:Ordinal deep space mission.[1][4]
Mission overview
Launch date
The Шаблон:Ordinal Arianespace launch of 2018 took place on 20 October 2018 at 01:45:28Шаблон:NbspUTC (19 October 2018 22:45:28 local time) from Ariane Launch Complex No. 3 (ELA 3) in Kourou, French Guiana.[1][5][4]
Pre-flight activities
The different parts of the spacecraft arrived in French Guiana between April 24 and May 9.[1] Deployment testing of BepiColomboШаблон:'s MTM 2 solar arrays (which will generate up to 11.2 kW of power[1]) were performed at the Guiana Space Centre in the SC5 facilities.[6] The MMO was integrated on the MPO between August 20 and 21. They were both integrated on the MTM between September 19 and 20 to complete BepiColombo. BepiColombo was assembled with its payload adapter on October 4, integrated on the launch vehicle on October 9, and enclosed within the fairing on October 11.[1] The launch readiness review toko place on 17 October 2018 in Kourou to authorise the start of the final operations.[4]
Orbit
The launch lasted 26 minutes and 47 seconds until separation, placing BepiColombo into a Mercury transfer orbit, escaping the Earth with a hyperbolic escape velocity of about Шаблон:Convert and at an inclination of about -3.8 degrees.[1][5] It is expected to be captured by and start orbiting Mercury approximately on 5 December 2025, after a 7-year travel that will include several flybys of the Earth, Venus, and Mercury itself.[7]
