I'm confused.
Which isn't unusual, I get confused a lot.
...the Earth-bound controllers haven't been able to communicate with it long enough to operate its ten instruments as yet... ...To rectify that, the Rosetta probe is going to fire up its thrusters and get closer to the comet's surface so that a firm data link can be achieved...
Rosetta hasn't been able to stay in contact for long enough to get useful communication going, so they are going to move Rosetta into a nearer orbit. But won't a nearer orbit reduce the orbital period, making each communication window shorter, making communication even less useful?
