SpaceX had already put more working Starlink satellite mass into orbit than every other active spacecraft combined. Let that sink in Everyone talks about Starlink accounting for roughly two-thirds of active satellites in orbit But the MASS comparison is even more extraordinary Jonathan McDowell's satellite catalog reveals that as of September 30: • Starlink's operational fleet: 6,197 tonnes • Every other active spacecraft combined: 5,222 tonnes That includes the International Space Station, China's space station, GPS, Hubble, weather satellites, military satellites, OneWeb, Amazon's constellation and everything else that's active in Earth orbit Starlink alone outweighs ALL of them combined For perspective, the ISS weighs roughly 420 tonnes and took more than a decade to assemble in orbit Starlink's working fleet already has nearly 15 TIMES that mass And the difference becomes even more staggering below 600 km: • Starlink: 6,197 tonnes • All other active spacecraft combined: 1,301 tonnes That's nearly FIVE TIMES as much operational spacecraft mass in the same orbital region And compared with other maneuverable spacecraft below 600 km, Starlink has nearly SIX TIMES the mass A single company has deployed more operational satellite mass than the rest of humanity's active spacecraft combined. And SpaceX is preparing to scale even further with Starship and next-generation Starlink satellites The satellite-count numbers were already extraordinary The MASS numbers reveal just how enormous SpaceX's lead has become
