Hello-
I wasn't sure how most people would like to see stuff posted. Or if this would interest many people. But in the interests of putting out more information, I created this topic as a place to put information on Venus Express science planning. If you have any ideas about this, let me know. Cheers- Don Merritt -------------------- --

Back in the days of chipped flints and ...
Early Mariner's were designed to use Canopus, which is near the south ecliptic pole and 2'd brightest star in the sky, as roll-reference. Before Mariner 10, they didn't have articulated high-gain antennas, so during extended missions, they often used alternate guide stars for roll reference. Not really a "faking it" program, but something similar. |
