MarkWhittington writes "NASA has unveiled a new prototype lunar rover, called the Chariot, a production version of which is hoped to be operational on the lunar surface by 2019. NASA is now testing the Chariot lunar rover in Arizona, on terrain that resembles the lunar surface." Perhaps Arizona's an even closer match to the moon's surface than is Texas, or Moses Lake, WA where NASA was testing the last time we mentioned Chariot. (Here's a bit of video from the Texas round.)

holy_calamity writes "New Scientist has video of Nasa's new Chariot lunar rover in action on simulated moon surface in Houston. As the associated story explains, the two-ton "truck" has a top speed of 20km/hour and is currently fitted with a plough, with additional back hoe and drill attachments to come. Sure it's not glamorous — more of a lunar tractor — but sure looks handy for establishing that permanent moon base NASA wants."

NASA Testing Lunar Rovers In Moses Lake, WA 116 comments
deadaluspark writes "I work at a local news station, and found out NASA was testing their lunar rovers in a nearby city. I pulled some strings and got our news director to send out one of our reporters. I would link to the original video on the KVEW website, but the video is screwing up on the badly designed, WMP only website. So I uploaded the package to youtube for everyone on Slashdot to enjoy. Very cool video of NASA toys in action." Don't believe anyone who says it always rains in Washington.

IIRC, NASA used the terrain around Ajo [wikipedia.org] as testing grounds for the first lunar missions.
I've been to Ajo, I spent a week there one day. It's a perfect location for simulate the moon; rugged, desolate, and devoid of any signs of human habitation.

You also had a population then that believed in creating science rather than it being someone else's problem. Today, you are much better off being a lawyer or PR consultant or something and just buying it. This is probably true for for many OECD countries. Science is not cool.

"One of the more unusual innovations is a pair of slip-on space suits attached to the back of the pressurized cabin. Rather than taking up room with a full-size airlock, a "plainclothes" astronaut simply slides into an empty suit, pulls a lever to close the hatch and detach, and walks away. The process can then be done in reverse to re-enter the cabin."

This way is actually much better. During the apollo missions the dust came into the LM with the suits. If the suits actually stay outside the inside of the rover will be very clean. The suits will need maintenance but this could be done outside in vacuum.

Why does it take so long for we Americans to get anything accomplished nowadays? Didn't the Apollo missions take only seven years to get from conception to landing, including development of command modules, lunar rovers, lunar modules, and a fairly reliable multi-stage rocket engine system? Why is a new lunar rover going to take 11 years to go into production when technology is so much more advanced now and innovation is at a faster pace than ever?

Okay, boss, this LTX-71 concealable mike is part of the same system that NASA used when they faked the Apollo Moon landings. They had the astronauts broadcast around the world from a sound stage at Norton Air Force Base in San Bernadino, California. So it worked for them, shouldn't give us too many problems.
four answers in order of importance (Score:5, Interesting)
first off, CHARIOT got to this point from nothing in 2 years. second, while you can say "we've been to the moon before" and be right, it's completely apples and oranges if you take even one small step beyond that.
0. i'll stick this one on top even though it's really part of another answer: You Aren't Excited About It. honestly that's the biggest problem. think hard about why your first impulse was to shrug this project off as slow and unexciting after you've read the other answers. then think about what's actually happening. then, and i'm completely serious, get excited about it! it's really exciting stuff! but this is a chicken-and-egg situation.
1. relative funding level. in this case, more money would actually help a *lot*. besides that, a lot of the money is going into rockets these days. the stuff the rockets are going to move around is sort of back-burner and shoestring (relatively speaking). unfortunately, all of this really needs to happen in parallel, because we don't want to get there and then have to figure out what we're going to do and how. Constellation is called an "architecture" for a reason. but the budget just doesn't support doing the necessary rocket stuff while adequately funding the basic conceptual experiments that give the rocket stuff raison d'etre. the analogs barely happened this year - in particular this one.
2. the NASA of Apollo was a completely single-minded organization. almost everything is different now, and NASA does a lot of work - very important work - that is not related (directly) to "putting stuff on the moon." but there is also a sad story to tell, mostly related to the competition for funding between 4 mission directorates spread across a bunch of centers (and their political relationships). at this point i'm almost convinced that it would be impossible for any single person to know everything that NASA is doing *even conceptually*. and going back to the first sentence of this point... the entire country was fully behind Apollo. it seems like hardly anyone even notices Constellation.
3. more complexity -> more testing. next time NASA astronauts are on the moon they're going to be doing a heck of a lot more than landing, grabbing a few rocks and going home. we're talking lunar infrastructure and long term experimentation, multi-day traverses, etc. this is orders of magnitude more difficult than Apollo, and from what i've heard/seen, Apollo people involved in the current effort would not hesitate to agree with what i'm saying here. the new rover is not going to be abandoned as junk after a few uses. this is a modular concept with a lot of intended uses.
4. did i mention funding? seriously. this is not a "mythical man month" problem at this point. funding comes from congress. congress allocates funds according to the demands of constituencies. that's you.
want this to look and feel more like Apollo did in its day? support it. especially politically, but even just talking about it and attempting to appreciate what's being done would help.

To your point 0, though: It would be a lot easier for the public to get excited about NASA work if NASA did a better job of presenting that work to the public. I know this has been said many times before, but that might be because it's a valid point. The problem as I see it is that the guys doing the work have bigger things to worry about than getting involved in marketing.

The astronauts will go up on an Ares I rocket. The equipment for a moon landing, this included, as well as the Earth Departure Stage will go up in an Ares V. After they rendezvous in Earth orbit they will then go to the moon.
