Le lancement d'Ariane VA255 serait apparemment prévu pour le 15 octobre prochain, avec Syracuse-4A et SES-17.
Si ça se vérifie, le lancement du JWST en 2021 est impossible.

SES-17 is based on the three axis stabilised Spacebus NEO satellite bus. 
It has a mass of more than 6,000 kg (13,000 lb), produces 15 kW of power and has a design life of 15 years.
Like all Spacebus NEO, SES-17 will use electric propulsion exclusively for both orbit raising and station keeping.

SES-17 will operate in conjunction with SES's other geostationary satellites 
and SES's medium Earth orbit O3b and O3b mPOWER satellites 
to provide connectivity services across the Americas and the Atlantic Ocean region.
