I don't think there has been any mistakes. The The new algorithm handles determining the required flight path to land at a chosen site with minimal fuel use. So it is completely independent of the system for choosing the site. I can certainly understand the fuel saving aspects of the new algorithm, but am curious about the addition of in-flight, apparently near real-time navigational changes, as remote in-flight navigational changes will have to be made long before atmospheric insertion. So I am wondering if a separate system is in the works for autonomous landing site corrections (within a limited range around the targeted landing site).

Please ignore that last post - that was one of the stupidest things I've said recently (read in the past week). NASA unfortunately has had its share of major mistakes so I guess I shouldn't infer that they always know what they're doing - history says otherwise.

During the simulation, there was a remote triggering for correction. That's an interesting question as to how it will actually be used. NASA seldom announces anything that isn't well tested/thoughout out. What do you think the mechanism will be for this correction capability?

Triggered how? By remote command or by autonomously deciding the initial site was unsuitable? Mars is too far away to remotely trigger real-time course corrections during decent.
