Timetable for Orion, "Artemis has landed" Options

Here's my overview of the schedule of NASA's Orion program ...

Orion's timetable:

A delay was noted today by Administrator Griffin:

Forget the lunar part (Ares V and Lander and Base), shift the LEO part first flight (Orion and Ares I) into 2015 or 2016, extend the LEO missions (2 or 3 each year) to ISS well into the 2020ies and you have reality. Assume about the same budget for manned missions like today and fewer, less capable missions. And stop even thinking about a manned mars mission.

I'm sure I don't have to remind people that this thread is not to get into politics in any way

I'm reading there are more changes.

- NASA Updates Ares I Launch Manifest (Feb 16)

Now Orion 3 is the first manned Orion flight, not Orion 5. Who knows more?

Nobody does. This program reaches far, far into the future and changes every month. I expect many changes, delays and cancelations. Be careful with every "manifest" you find, ex post it will almost certainly be wrong. The current plan is "pay as you can", so every budget change will effect the timetable, same for technical problems. There are at least three cornerstones in every project: budget, performance and schedule. They seem to change all three constantly.

I prefer planetary probes: A planetary launch window fixes your schedule pretty well. So you shift between performance and budget and I am surprised how good the results often are. There are cost overruns (MER, DAWN, Messenger) too, but imo pretty modest ones.

What about the asteroid mission?
