SpaceX — a success story without equal! from 120 Starlink satellites deployed in 2019, to an incredible 3,180 in 2025, a cumulative total of 12,307 sats deployed in only 7 years, and more sats in orbit than the rest of the world combined! Well done @elonmusk and the entire SpaceX Team — looking forward to an exciting space future

@All_inspace From shower tiles to heat shield tiles
English
Current dedicated LEO costs: ~$1,500/kg (Falcon Heavy) to $25k/kg (small dedicated like Electron at exactly $7.5M/300kg).
Falcon 9 dedicated ~$2,700–$3,200/kg. Rideshares ~$7k/kg.
No single average — scales massively with vehicle size and dedicated vs shared. Heavy reusables crushed prices for big payloads; small dedicated stays higher per kg.
