Mars Rover Wheels, one large machined piece?
was watching NASA a couple of days ago w/the sound off, it
looked like they were machining the current Mars rover wheels, out of a _single_ piece of metal. after turning the sound on, it was a little late to get any verbal confirmation but it does seem likely. further, the wheel and tred are part of the single piece, along with the hub. the rest of the assembly is the "inner-tube", something molded into the metal housing. is _that_ what i saw? Thanks! --Loren ps, if yes, talk about _custom_wheels_(!), yowser!! |

The wheels are combination rims and springs. Pretty ingenious for
saving weight. We will probably see American Chopper try it in their "Rover Memorial" model next. :-) Richard J Kinch wrote: Loren Coe writes: was watching NASA a couple of days ago w/the sound off, it looked like they were machining the current Mars rover wheels, out of a _single_ piece of metal.

Last "article" just showed a picture looking back at the lander and the parachute and that was it , no write up nothing and on page 20. Two robots on a different planet and no one seems to care... Loren, did the filters work? |

Loren, did the filters work? Just remember, when you are sending things interplanetary delivery, fuel cost trumps all other cost considerations. Machining from a billet means you don't get excess weight from connectors holding it together. |

Loren, did the filters work? at first, not real well, then when i tried again, i couldn't really find anything on the NASA site to view. after reading your query i tried again and, YES(!), they do indeed work. two things seem important, letting your eyes/brain adapt and rotating the filters as you view (maybe swapping between eyes). at some point i believe you find a sweet spot, maybe just minimizing reflection (i wear spectacles). however, tonight i viewed images on a Georia Tech site, that could be part of the difference. the upper left 1/3 of this one is great: http://bastille.ns.gatech.edu/gallery/album04/aab there is plenty of 3-d effect, almost too much. i used the first pair i removed from the bundle, red and aquamarine with all attempts, just holding the media in front of my eyes/glasses while viewing the screen. my 19" is running only 1152x??? so resolution s/b no issue. i should try to get it going at 1280x..., it could be better. anyhoo, fun and games, and a bit of nostalgia. the last 3-d movie that i recall seeing was, "Mars" something or other. the "martians" were hurling rocks with big sticks, they made the audience duck behind the seats(!). there was a western movie with a similar effect using arrows. that western, the name escapes me, is somewhat of a classic now, but no metion ever of it's three-dimensional release. now i am wondering if it was color....? Brad, thanks for the media and the reminder. great fun, sending about 1/2 of these to my daughter in Albuquerque. she just got her cable modem and viewed the NASA site for the first time this week. --Loren ps. while searching i found site that offers another way to view 3-d w/o the filters: (i didn't try this) http://www.cpcug.org/user/clemenzi/s..._3DViewer.html |

Also suspension components (2nd to last photo) Very cool. Wonder how much of my tac dollars went into those "NASA" hubcaps. I would have settled for Cragers. GTO(John) |

The last Haas catalog/magazine we received at work had an article about the
wheels. The finished part weighs less than 10% of the blank. Yoi. "GTO69RA4" wrote in message ... http://www.nextintent.com/parts.html Also suspension components (2nd to last photo) Very cool.

Mars Rover Wheels, one large machined piece?
I was going through the past days photos and noticed a couple of
things. The spheres seem to be located in three different situations , I take it they are from flying molten metallic ore from impact strikes , did they see stuff like that on the Moon? And the tracks on one picture look like they are having trouble or turn struts for fun, and back track or something. Anyhow, in one spot and in the tracks themselves it looks like the soil is somewhat sticky to itself. I wish the rocket scientists would speculate or just say more. Also, there is one picture from orbit of one of the sites that shows wandering dark paths from the craters like from the wind and it "sticks" at different times... I'd like to see a lot more of the terrain from orbit. They seem to have hit the target ellipse almost right in the middle , but why in the middle of a plain? I would have put it closer to the mountains they named after the last shuttle people. I ran into this in the paper. www.moontomars.org that wants suggestions on what to do from the public, haven't been there myself yet. |
