Celebrating the Return of Dog-Dish Hub Caps: New VW Beetle with “Heritage” Alloy Wheels

Friday, October 12th, 2012

You see in my day, people’d be putting wheel covers to make simple steal wheels look like aluminum or magnesium alloys.

But these days VW is offering wheel covers on top of alloy wheels to make them look like old-school hub caps on steel wheels.

See? Here are your 17″ heritage alloy wheels on a 1013 VW Beetle:

Tomorrow’s Mission to Mars Will be a Lot Bigger Than NASA’s Previous Efforts – Meet the Mars Science Laboratory’s Curiosity Rover

Friday, November 25th, 2011

When you’re on a mission to M/A/R/R/S, you gots to pump up the volume, like how NASA is doing with tomorrow’s launch of the Mars Science Laboratory (MSL).

Check out this shot showing the size of the new rover’s wheels, via our California Academy of Sciences.

Three rover wheels at #NASAtweetup show the relative sizes for Curiosity, Spirit/Opportunity, and Pathfinder:

Check it:

Curiosity will be five times as large, and carry more than ten times the mass of scientific instruments as the Mars Exploration Rovers Spirit or Opportunity.”

Here’s a family portrait:

Bon Courage, NASA

NASA’s Mars Science Laboratory mission is preparing to set down a large, mobile laboratory — the rover Curiosity — using precision landing technology that makes many of Mars’ most intriguing regions viable destinations for the first time. During the 23 months after landing, Curiosity will analyze dozens of samples drilled from rocks or scooped from the ground as it explores with greater range than any previous Mars rover.

Curiosity will carry the most advanced payload of scientific gear ever used on Mars’ surface, a payload more than 10 times as massive as those of earlier Mars rovers. Its assignment: Investigate whether conditions have been favorable for microbial life and for preserving clues in the rocks about possible past life.

Plans for the Mars Science Laboratory call for launch from Cape Canaveral Air Force Station, Florida, between Nov. 25 and Dec.18, 2011, and arrival at Mars in August 2012.

The spacecraft has been designed to steer itself during descent through Mars’ atmosphere with a series of S-curve maneuvers similar to those used by astronauts piloting NASA space shuttles. During the three minutes before touchdown, the spacecraft slows its descent with a parachute, then uses retro rockets mounted around the rim of an upper stage. In the final seconds, the upper stage acts as a sky crane, lowering the upright rover on a tether to the surface.

Curiosity is about twice as long (about 3 meters or 10 feet) and five times as heavy as NASA’s twin Mars Exploration Rovers, Spirit and Opportunity, launched in 2003. It inherited many design elements from them, including six-wheel drive, a rocker-bogie suspension system and cameras mounted on a mast to help the mission’s team on Earth select exploration targets and driving routes. Unlike earlier rovers, Curiosity carries equipment to gather samples of rocks and soil, process them and distribute them to onboard test chambers inside analytical instruments”

Do You Need a Rear Brake on Your Bike to be Legal in California? I Don’t Know Anymore

Wednesday, October 12th, 2011

You know, I think they went and changed VC 21201 on me. It used to talk about being able to make your rear wheel skid, but now:

“21201.  (a) No person shall operate a bicycle on a roadway unless it is equipped with a brake which will enable the operator to make one braked wheel skid on dry, level, clean pavement.”

I’ll have to look into this.

Here we have a bike with no rear brake on McAllister. (I know what you’re thinking, but this bike isn’t a fixie, it freewheels.)

Not exactly safe, IMO, but not necessarily illegal either, apparently…

Hilarious: Volvo Station-Wagon Owner Mocks Ferrari with Fighting Moose Fender Badge

[UPDATE: All this makes writer Mickey Kaus wonder if #TheyHaveMooseInChina?]

Do you prefer the original?

Or the parody, as recently seen on Fulton Street?

Now that’s a moose and a Volvo pilot with attitude.

I feel we should rastafy him by … ten percent or so.”

NoPA Tableau: Accident-Damaged Bikes Live Forever on the Mean Streets of San Francisco

I don’t know how long this ride has been sitting locked up on Fulton in the NoPA part of the Western Addition but it feels like a period of months now:

Sometimes it falls down, but then people prop it up again.

The rear wheel has been pretty much taco’ed – see?

I’ll bet there’s a story behind that.

Now you’d think the cop who’s walking a beat in this area (while constantly swinging his billy club) around would notice at some point and have this bike hauled away…

You’d think.

Because the little monsters will mess you up.

That’s why.

Now, take this carcass into a bike shop and they’ll start talking about Chuck the Wheelbuilder and how great he is and then they’ll quote you a price that exceeds what you paid for the bike in the first place.

Oh well.
