Triggered?

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.

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?

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.

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).
