We're now 45 days from landing, so as of 23 Jun please post all comments related to the end of the transit to Mars here.

Go Curiosity!!!!

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The baseline plan was...

X-Band DTE
Tones up until just after 'chute deployment in the MER stule

UHF
Bent pipe relay 8kps via Mars Odyssey
Store and Forward from Entry to Landing 8kbps via MRO ( that we would get at about landing +4 to 5hrs or so )
And partial carrier only via MEX

Now - the only change is the bent pipe 'live' 8kbps telem via MODY is in jeopardy.

I bet they'll find the time between now and landing to re-tweak MODY's orbit, burn a bit of prop, and get it back in place for bent-pipe relay. There's several decades of prop margin onboard.
