How large would an event have to be to seriously impact the electronics on-board MSL? I remember how the MERs avoided the really big ones on their cruise around Halloween 2003, with lots of relief on the ground.

According to Curiosity and the Solar Storm, CMEs present no threat to MSL.

"With solar activity on the upswing it's only a matter of time before a CME engulfs the Mars-bound rover. That suits some researchers just fine. As Don Hassler of the Southwest Research Institute (SWRI) in Boulder, Colorado, explains, 'We look forward to such encounters because Curiosity is equipped to study solar storms.'

Encounters with CMEs pose little danger to Curiosity. By the time a CME reaches the Earth-Mars expanse, it is spread so thin that it cannot truly buffet the spacecraft."

TCM-1 scheduled for Jan 11th, dv 5,5 m/s.
Then equipment tests for one week, starting from Jan 15th.
Let's see if we'll get some picture(s) from interior.

I hope this also applies to MESSENGER!

Not sure if mentioned here before, but radio amateurs from Germany, Bochum have received signals (X-band telemetry) from MSL last year.
It should be the first reception of the MSL outside the official NASA DSN and USN tracking station at Dongara, Australia.

The computer that received the software fix, is it the sole computer for MSL or was it located on the cruise stage, decent stage, or the lander? If there are separate computers, will they also need a software fix for the same type of problem?

MSL has 2 identical main computers which control all aspects of flight, EDL and the surface operations, one is a backup. There is also a fly away controller on the decent stage which enables the descent stage to keep flying away.

So no other computers need updating.

Forgive me if this has already been answered, but I submitted my name many months ago for the chip on the MSL, I was wondering if there is a site where I can confirm that it's there.

A quick search of the Forum revealed this http://www.unmannedspaceflight.com/index.p...st&p=167391

The MSL website only carries participation maps:

http://marsparticipate.jpl.nasa.gov/msl/pa...rname/worldmap/

Looks like you'll have to trust that your name went in.
Hopefully you made a copy of your certificate.
