Proteus Prototype Watercraft

The front page of today’s San Jose Mercury covered the unveiling of a new high-tech watercraft called Proteus:

Dr. No, your escape vehicle is ready. The 100-foot, spider-shaped contraption skimming around San Francisco Bay looked more like a James Bondian vessel than it did a new class of watercraft. But that’s exactly what its inventor, Ugo Conti of El Cerrito, says he’s achieved.

This thing looks really wild. It’s hard to judge the size from the pictures, but the specs say the beam is 50 feet (15.2 m), so it’s probably 100 feet (30.5 m) in length.

The WAM-V, short for Wave Adaptive Modular Vessel, was built by Marine Advanced Research. Check their home page for specs and more detailed pictures. They have an interesting list of sponsors as well:

  • Autodesk (Autodesk Inventor 3D design software)
  • Cummins (Cummins MerCruiser diesel engines)
  • Twin Disc (gears and propulsion)
  • Timet (titanium springs)
  • HP (computer systems)

NASA Ames Research Center

Today I chaperoned a school field trip to NASA Ames Research Center here in Silicon Valley. The educational program focused on wind tunnels and some aspects of creating vehicles for space travel. Overall it was interesting and seemed to hold the kids’ interest pretty well. Of course I volunteered because I’m interested in this great facility right here in our backyard. Anyone commuting near highways 85, 101, or 237 in Mountain View has seen this facility’s impressive buildings.

Tonight I did a little digging to see what kind of online information I could find. The official Ames Research Center site looks very NASA-formal, but didn’t seem to have anything interesting.

A little more digging revealed the Ames Wind Tunnel site which has the pictures shown below and some more technical data on two of the active wind tunnels. It looks like the full list of wind tunnels on site includes:

  • 80×120 (feet) subsonic
  • 40×80 subsonic
  • 11×11 transonic
  • 9×7 supersonic
  • 8×7 supersonic
  • 12 foot pressure tunnel

(I had to look up ‘transonic’ to learn it covers the range of speeds just below and just above the speed of sound — about mach 0.8 – 1.2. Subsonic and supersonic are the speeds below and above the speed of sound, respectively.)

Today we got a personal tour of the 80×120 tunnel which is the largest in the world. Its last test was in 2003 with the parachutes for the Mars Exploration Rovers Spirit and Discovery. At that time, the tunnel was going to be closed down due to budget cuts, but in 2006 the Air Force signed a 25-year lease to operate the facility with a focus on helicopter testing.

The smaller wind tunnels are part of the Unitary Plan Wind Tunnel complex which is registered as a National Historic Landmark. It looks like this facility is still quite active in part because they can achieve supersonic speeds.

Shuttle Mission STS-116 Lands in Florida

Shuttle mission STS-116 landed in Florida almost an hour ago at 5:32pm EST. The NASA landing blog said the flight covered 5.3 million miles, orbited the Earth 204 times, and lasted just under 12 days, 21 hours. (I wonder how this duration compares to the other shuttle flights…)

Check out Yahoo!’s Shuttle Full Coverage news page or NASA’s STS-116 Mission page for news and multimedia.

I like this picture of the first spacewalk — the astronauts are doing construction on the International Space Station while in orbit over New Zealand and Cook Straight in the Pacific Ocean:

Shuttle STS-116 Night Launch

Yesterday we caught the nighttime launch of shuttle Discovery on mission STS-116. Check the NASA site for more images from the launch and ongoing updates from the shuttle. In addition to delivering another truss for the International Space Stations, this mission is also going to rewire the entire electrical system!
