For those like me who love the technical aspects of all this - I've been digging around a bit, and currently (or recently) - spacecraft are using the following DTE bitrates

MEX - 104857.6 bps
Genesis - 16590 bps and 47400 bps
MGS - 42666.7 bps and 8000 bps
MER Cruise - 2212 bps and 7110 bps (via MGA)
MODY - 124425 bps and 39816 bps

In the case of two values - it is likely that the smaller value is using a 35m DSN dish, and the larger a 70m DSN dish.

For info on MER UHF passes in the future - check out some ENORMOUS stats - http://mgsw3.jpl.nasa.gov/seq/relay/srpr/0...S00.apgen.notes

April 1st was D.o.Y 91 - so these are April 20th and beyond -

I believe 32 degrees elevation is the limit at which they'll do a 256kbps pass instead of a 128 kbps pass - but these stats confirmed what I thought - that the average sol will include 100 - 300 mbits of relay data - with as much as 158 mbits in a single pass and up to 4 passes per sol - but short passes are ignored as the downtime of operations to get the small ammount of data back doesn justify the interuption to MER and MODY ops.
