The mission tied Atlas V’s personal file by lofting about 18 tons into orbit. The satellites had been initially positioned into orbits roughly 465 kilometers above Earth, from which the Amazon mission crew will increase them to their operational altitude of about 630 kilometers. Satellites will now be raised from ~465 km to ~630 km altitude. The following Amazon launch (Leo-07 on Atlas V) is scheduled for Might 22, 2026.
