What changed in space, and which companies it changed

The economics of space were rewritten by one variable: the cost of putting a kilogram into orbit. Reusable boosters cut that cost by an order of magnitude, and everything downstream followed. Satellites that once had to last fifteen years because replacing them was ruinous can now be built cheaply, launched in constellations and replaced on a short cycle. The sector's structure follows directly from that shift.

Launch is the foundation, split by payload class. Small dedicated launchers serve customers who need a specific orbit on a specific date and will pay for it. Medium and heavy lift vehicles carry constellations and institutional payloads at far lower cost per kilogram, and reusability is what separates the current generation from the previous one. Launch is capital intensive, lumpy in revenue, and unforgiving of failure.

Satellite manufacturing and components supplies the spacecraft: buses, propulsion, structures, solar arrays and the specialised electronics that survive radiation and thermal cycling. The move to mass produced small satellites turned parts of this from bespoke engineering into something closer to a production line.

Satellite services is where recurring revenue lives, and it divides by what the satellite sells. Earth observation sells imagery and the analytics derived from it, to agriculture, insurance, defense and finance. Communications sells connectivity, whether backhaul, maritime and aviation links, narrowband machine to machine service, or direct connection to ordinary handsets. Position and timing services underpin far more terrestrial infrastructure than most people realise.

Ground systems is the least visible layer and an unavoidable one: antennas, gateways, terminals and the software scheduling contact windows. A constellation is useless without the ground segment to command it and receive its data.

Defense and civil space is the demand side that funds much of the rest. Military space budgets cover missile warning, secure communications, surveillance and, increasingly, resilience of orbital assets. Civil agencies fund exploration, lunar delivery and science missions. Both procure through multi year programmes, which makes contract awards more informative for these companies than quarterly commercial trends.

The recurring tension across the sector is between programme revenue, which is visible and slow, and commercial revenue, which is faster growing and far less certain.
