For decades, the suborbital launch sector was largely a backwater. Militaries tested ballistic missiles, scientists conducted experiments, and engineers tested new technologies. A sounding rocket is small potatoes compared with orbital rocket launches and the glamor of human spaceflight. Few people paid much attention.
All that has changed in recent years as Virgin Galactic and Blue Origin and their billionaire owners — Richard Branson and Jeff Bezos — started launching themselves and others on suborbital joyrides.

This year has been no exception. The first half of 2022 saw Blue Origin send 12 people into space on two New Shepard flights, a Chinese company conduct six launches in a program to develop aa suborbital spaceplane and hypersonic transport, South Korea and Iran perform flight tests of three different smallsat launchers, Germany test technologies for reusable rockets, and first-ever commercial launch from Australia. And, a great deal of science was done.(more…)
