Revision as of 16:10, 21 August 2015
Several missions in this campaign require targeting specific orbital inclinations. Is it possible to see exactly what inclination a vessel is at? Hitting a specific inclination, to two decimal places no less, seems pretty tricky, especially without SAS.
Less specifically, the terminology used definitely ramps up in this campaign (polar orbits, sun synchronous orbits, Molniya orbits, sidereal time). The missions for polar and sun synchronous orbits describe them pretty well, but Molniya orbit and "1/2 sidereal day" are less clear. ~tacocritic (sign talk pages)
