A major NASA observatory reaching orbit aboard a commercial launcher has again drawn attention to how launch services are bought.

Buying launch services from private providers, rather than operating government rockets, has spread over the past decade or so.

How procurement changed

Agencies once developed and operated launch vehicles themselves. Today it is standard to tender launch services mission by mission and match a vehicle to the payload and target orbit.

The approach is credited with lowering launch costs, though it also raises dependence on a small number of providers.

Heavy payloads, heavy lift

Large observatories need heavy-lift vehicles because of their mass and volume, and few operators worldwide field rockets in that class.

With few competitors, bargaining power is limited. That structural problem is part of why several countries continue developing their own heavy-lift vehicles.

Launch capacity in Asia

Korea, Japan, China and India have each developed indigenous launchers, and competition for commercial satellite launch contracts runs through the region.

Reliability records translate directly into contracts here; success-rate statistics function as a de facto barrier to entry.

An industrial view

A larger launch market feeds downstream into satellite components, ground station equipment and data services. Those component supply chains cross many borders.

This paper approaches the space sector through supply chains rather than as a contest between states, on the view that it yields more usable information for readers.
