Wouldn't be much of a ride -- she may be big but she's slow!
Wonder whether the toenail polish would look different under martian lighting? Perhaps not, they're not far off from the color of the sky -- a bit bolder tho  --Emily -------------------- |

Man, MSL is indeed a big beast... good thing there are no critters on Mars after all, because they'd run like hell in any case as soon as they saw it!
 Thanks for the sneak peek, Emily!

Well, think of it this way -- a MER is about the size of a golf cart. MSL will be about the size of a Jeep. No wonder they want to find a way to just gently drop the thing onto its wheels and not have to worry about a platform big enough for it to roll off of...

And of course, after that scale up, the landing date would have to be on a SUNDAY!!!
Good pictures, thank you. That sure is a big critter. Send it to the Columbia Hills with a winch, in case any more of Sprit's wheels seize up. |

Sunday, SUNDAY, SUNDAY! We're gonna turn the entire valley floor of Melas Chasma into a 10-foot deep MUUUD PIT!

As I noted in another thread, if Marvin were around, he'd develop sudden urinary incontinence syndrome when he sees MSL come rolling over the top of a dune, the camera mast head swinging around, the laser spectrometer firing. Speeded up of course, not at glacial speed. |

The first picture to grab my attention, and probably the attention of many people, was the top one. The door begins to open, and there are the wheels of the beast.
 I think pictures depicting its rock climbing abilities were a close second. All of the pictures were amazing.QUOTE (elakdawalla @ Jun 20 2007, 10:18 PM) Sunday, SUNDAY, SUNDAY!

I was kind of thinking along those lines, but I'm really dreaming about the trenches they should be able to dig.

I saw the "Scarecrow" at JPL's Open House on May 19... I'd post up the pictures I took of it, but my digicam is in my room upstairs. A mock-up of the rover's Multi-Mission RTG was also on display.
Not to state the obvious, but the Skycrane system is gonna have to produce a (bleep)-load of thrust to get that behemeth on the ground safely...

How many meters per day will the MSL be able to travel without doing any science?
And for all the rovers, are the motors in the wheel hubs? |

QUOTE (punkboi @ Jun 21 2007, 01:53 PM) ...Skycrane DESCENT MODULE... That should be MSL Descent Module. Skycrane is the name of a maneuver, not a piece of equipment. I hate to be a pill about this, but I see this type of error being made by the thousands in the general press when the time comes. Are we going to ignore it or will we gripe about "inaccuracies in the press"? If it's the latter, we better get our act cleaned up first. When I first brought this up, I suggested that NASA/JPL take the path of least resistace -- and best PR -- and actually call the decent module the "Skycrane". I was told this was not an option. (To the management: in a thread that has discussed the flightworthiness of toenail polish, I don't think this should be deleted as being OT. )
