Tom & Jerry are already up there: The two GRACE satellites have got these nicknames.

Itchy & Scratchy, then.

Why are people proposing dual names? 

There is only a single MSL flight rover.

Itchy for the descent stage, Scratchy for the rover (since it will be 'scratching' Martian rocks.  So to speak) ;)

JPL announced today that "Curiosity" is the winning name.

http://mars.jpl.nasa.gov/msl/news/whatsnew/index.cfm?FuseAction=ShowNews&NewsID=99

Quote
Twelve-year-old Clara Ma from the Sunflower Elementary school in Lenexa submitted the winning entry, "Curiosity." As her prize, Ma wins a trip to NASA's Jet Propulsion Laboratory in Pasadena, Calif., where she will be invited to sign her name directly onto the rover as it is being assembled.

It looks like my younger siblings failed in their assignment to win a trip to JPL for me to chaperon. ;)

People now usually refer to the current rovers as Spirit and Oppy (apart from the MER1/MER2 folks ;) ).

So now we have a choice between Ami, Advo, Sunny, Purse, Curie, Wonny, Perry, Journey, or Vissy. :)


So much the better! Curiosity will be powered by radioactive decay. Marie and Pierre Curie were awarded the Nobel prize in physics for their studies of radioactivity.

There is an excellent MSL briefing at:

Yes it is, thanks!

Not very encouraging hearing about serious power issues (along with actuators, avionics, and funding). If the mass goes up significantly, I wonder if the Atlas selected will be able to accomodate?

They can add another solid

Perfect. Thanks Jim.
Gotta love a flexible architecture!  :)

Except that solid will not come without a price tag.

Well it would probably cost them to break contract...and pay even MORE for D4H...if even possible.

Or they can cut back on science instruments...

Pay them the money to get the job done. Simple as that.

Yeah, it's as simple as that. Sacrifice the future planetary programs so this budgetary black hole could finally fly. For someone waiting for the next outer planet flagship, forgive me for not being a fan of that option.

No, it is just an optional service and not big deal to add.

I meant to break contract and go with D4H instead of Atlas, or is that what you meant too?

I realize adding a solid is no biggy.

It is. Or Congress can give NASA the stiff for always going over budget on their projects.

Like it or not, they approved to continue this 'black hole'. I agree, it is out of hand, but so is EVERYTHING I have seen lately, on all fronts.

I'm not being confrontational, just realistic given the current state of things. The whole process needs to change to make sure major R&D isn't in the plan for a mission: use existing technologies. Once that happens, we can get to the other planets, which I too agree holds very good promise.

FWIW, Alan Stern apparently tried to make some tough decisions and force teams to have a better track and control of costs, but he obviously stepped on someone's toe or met too high a resistance. So the process is entrenched and isn't changing any time soon.

After all, why would someone propose a reasonable cost for a mission proposal when someone else can deliberately underbid/underestimate costs and just act innocent asking for more $$$ aftwerwards?

BTW, I'm not arguing MSL should be canceled at this point, but the repercussions of its overruns should be born out by potential future Mars missions.

There is no contract that would be required to broken.  ULA could switch the boosters with the appropriate $.  It can't happen at this time, too many mods to the fairing and VIF.

What is the knock on affect of adding a solid? Would it change the G and vibration enviroment enough to break anything?

I can't think of any mass increase the EDL system can handle which at the same time puts the launch mass beyond the Atlas 551 capability.

Okay cool, we were both on the same page with that one. Thanks.
