The difficulty was simply that Hern VI was not a responsive enough space craft to benefit by really quick orbital corrections.

Time for first orbital correction.

Their reserve fuel is adequate for orbital correction.

But, I do point out, as Sallah does, that there's enough in the Yoko's sump tank for centuries of minor orbital corrections.

It'll still make orbital corrections, but that's all.

A hydrazine propulsion system was used for orbital correction.

I gather you've been working on an improved algorithm for those orbital corrections.

Designed and manufactured in the United States by Aerojet, the system was used during launch to produce supplementary thrust and on-orbit to provide orbital injection, orbital correction and the spacecraft's deorbit burn.

The violent gravity waves emanating from the planet require constant orbital corrections, but the added work might prove worthwhile due to the possibility of life on the planet.

After several more orbital corrections, on 11 September, the vehicle began its descent to the lunar surface.
