There are 7 to 10 remaining Proton-M rockets that need to be utilized.

PlanValue 2.0Jan 6, 2026Before, it was planned to launch NEM on the first orbital mission of Angara-A5M, which is not the safest option for such an important module. Proton-M for this launch is already built. They have to find ways to use already built Protons (remaining 7-10 of them), after all. 3/6
