Ce qui est bien avec Proton, c'est que vu le taux d'échec il y a pas mal de suspense à chaque lancement ! :D

Trêve de plaisanterie : quelqu'un sait pourquoi l'orbite d'Intelsat 22 est aussi étrange ? (475km x 65 000km)

LVM a écrit:Ce qui aura permis : (a) au lanceur de gagner en capacité d'emport (environ 200 kg selon ILS) et (b) à sa charge utile de gagner en durée de vie.

Et pour quelle raison tous les lanceurs ne suivent pas toujours ce type de trajectoire, si c'est si efficace ? Personne n'y avait pensé avant ?

Je lis aussi sur CapcomEspace que le Vol 110 d'AR4 était la première orbite supersynchrone européenne.
