Satellite communications sits within Space & Aerospace, the youngest endeavor on this list, and the fastest-growing in strategic and economic weight — a category whose own scale remains unverified (only a stale, non-primary (2018, Wikipedia-sourced) figure was found; it is not used here). Satellite communications is one of 17 of the category's 20 items directly backed by institutional trackers — UNOOSA, ITU, ESA, FAA, NASA, Satellite Industry Association, Secure World Foundation, US Space Force — rather than an editorial judgment call.
