Propulsion systems on SmallSats and CubeSats are becomingmore common as launch vehicles like SLS begin providing rideshares to destinations beyond low earth orbit. While these spacecraft are a solution to achieve advanced science objectives at lower cost, they are still subject to the same rigorous standards as other larger spacecraft, such as NASA STD-5019, due to the high pressures within their propulsion systems at launch. A Post Launch Pressurization System would allow a spacecraft to be launched at low pressure, then be pressurized through the controlled chemical decomposition of a solid reactant after the spacecraft is jettisoned from the launch vehicle. This increases the safety of the secondary spacecraft, and effectively mitigates risks to the launch vehicle and other payloads.
