Solid rocket stages and how they perform mission-precise orbit insertions
Most rocket launches culminate with liquid-fueled upper stage engines turning off at exactly the precise millisecond a host of parameters — such as flight path angle, orbital inclination, apogee, and perigee — are all met simultaneously. So then how do solid propellant upper stages like those used on the Antares, Pegasus, and Minotaur fleets from…
