The latest Aviation Week has a couple of short updates on these two missions. ExoMars, as previously reported, has slipped to 2016. ESA has decided to cap its contributions for this 1.2B euro mission ($1.6B) at 1B euro. It will seek contributions from NASA and/or Russia for the rest.
For MSL, a number of tubes in the descent stage have faulty welds and these are being replaced. This is not expected to impact the schedule.
