Week in Space Data, every Friday.
Compare major satellite constellations side by side: orbit, planned size, dated satellite counts and deployment progress
Rows checked 2026-10-11 against the source linked on each row (six read the constellation profiles checked 2026-10-10). Every satellite count carries its own date: catalog counts are objects in CelesTrak’s public group for that constellation, synced daily; other counts are the cited source’s figure on the date shown. Fields no source supports are marked "Not on record".
