>Looks like quite a feat to qualify a spacecraft power supply!

It's actually a hell of a feat to get any kind of electronics certified for outer space use.

The atmosphere we have blocks a HUGE portion of ionizing radiation, including x-rays and gamma rays. Those forms of energy will play merry hell with any kind of sensitive electronics, so they have to be suitably ruggedized -- far more so than even most military specs which mostly call for shock, impact, and exposure to elements. Since they can be supplying power to sensitive electronics, where half a volt can be the difference between containing and letting out the magic smoke, that sort of regulation is absolutely key.
