Sea-Based X-Band Radar. Wikipedia:
The Sea-Based X-Band Radar is mounted on a fifth generation Norwegian-designed, Russian-built CS-50 twin-hulled semi-submersible drilling rig. The hull was originally built at Vyborg Shipyard, hull number 101. Conversion of the vessel was carried out at the AmFELS yard in Brownsville, Texas; the radar mount was built and mounted on the vessel at the Kiewit yard in Ingleside, Texas. It is nominally based at Adak Island in Alaska but can roam over the Pacific Ocean
The SBX failed during a flight test on January 31, 2010, designated FTG-06. The test was a simulation of a North Korean or Iranian missile launch. The test failure arose from two factors, the first being that algorithms in the SBX radar software which are designed to filter out extraneous information from the target scene were left disengaged for the test, and the second was a mechanical failure in a thruster on the kill vehicle.
During flight test FTG-06a on December 15, 2010, the SBX performed as expected, but intercept of the target missile was again not achieved.

Cyanotypes, by Christian Marclay (Flash):
The photograms in this exhibition are made with music cassette tapes he has physically disassembeled. In some, the plastic cases form austere grids.
The cyanotype process dates to the dawn of photography and was developed by the English scientist Sir John Herschel in 1842. Using a light-sensitive chemical mixture, these cyanotypes were created by placing objects directly onto the surface of paper coatd with the mixture. The resulting blue photograms reveal a silhouetted image that varies in darkness due to the opacity of the objects.

Oscar Hermitte: Urban Stargazing (via):
The Urban Stargazing project focuses on bringing back the stars in the city sky by recreating existing constellations and adding new ones, narrating old and contemporary myths about London. Twelve groups of stars have been installed at different locations in the city, and can only be observed by the naked eye at night time.
Or: if you go to certain open spaces in London, and stand in the right spot, you can see new, special “constellations” that don’t exist anywhere else, designed for the city sky (as pictured above, and it’s worth enlarging the images).
Each constellation is a triangulated struture made out of clear ø 0.6mm nylon line, ø 0.2mm polyethylene braid, ø 0.75mm fibre optic and a solar powered LED. During the day, the battery is being recharged by the solar panel and the circuit switches ON the LED when it is dark enough to observe stars.
In order to have the constellation in the air, the team uses a telescopic catapult to fix the structure on top of trees.
It’s well worth reading the pages on this one, so you get the idea.

Andrew Cockburn On Drones
Andrew Cockburn’s recent subscriber-only article, Drones, Baby, Drones in the London Review Of Books covered the US military’s recent favourite toy, its history, and why it may not be all it seems. I thought it deserved a summary for a wider audience.
The US has tried automated systems before:
Igloo White, which cost $7 billion, was an early attempt to automate the battlefield: tens of thousands of sensors, designed to pick up sound or movement, each one in radio contact with computers in Thailand, were scattered around the jungles of Vietnam and Laos in the hope of locating and targeting enemy supply columns on the Ho Chi Minh trail. But the Vietnamese quickly learned to move the sensors or make them send false signals and the experiment was abandoned in 1972.
There were also much-publicised claims for advances in technology in the Gulf War, the bombing of Serbia, and in Iraq after 2003. In each case, watchdogs (such as the US Government Accounting Office) claimed after the conflicts - when nobody was watching - that the programmes tended to produce much worse results than were claimed.
The last decade’s conflicts in Iraq and Afghanistan, and the distaste for casualties from the western public, have meant a bonanza for those making automated systems:
While American and British casualties on the ground in Iraq and Afghanistan ticked upwards, the skies grew dark with target-seeking aircraft, manned and unmanned, operating under such codenames as Constant Hawk and Angel Fire. Many of these systems were vastly expensive: one airborne system for detecting roadside bombs, Compass Call, cost $70,000 an hour.
Unfortunately, as with previous systems, they may not have actually worked that well:
In 2007, an intelligence unit in Baghdad called the Counter-IED Operations Integration Center analysed hundreds of these missions and concluded that most of them had ‘no detectable effect’ on the enemy.
That hasn’t stopped the funding for new projects, such as Blue Devils and Gorgon Stare, developed by MAV 6, whose CEO, David Deptula, used to be an Air Force three-star general. That said, maybe we don’t have much to fear:
Gorgon Stare’s camera images could not distinguish humans from bushes, or one vehicle from another. It had severe problems working out where it was. It broke down, on average, 3.7 times per sortie. The testing unit recommended that it shouldn’t be deployed, advice rejected by higher authorities, who quickly dispatched it to Afghanistan.
It’s not just the military. Despite Rick Perry’s pledge during his abortive run to be a presidential candidate that he’d deploy drones at the Mexican border,
when the Department of Homeland Security compared the relative performance of unmanned Predators and manned light Cessna aircraft in detecting illegal border crossings, it found the old-fashioned plane to be ten times as effective and 30 times cheaper. (Keeping a drone in the air involves two or three times as much backup manpower as a jet fighter like the F-16.)
It’s bad enough that drones are expensive and unreliable, but as events in Iran have shown, they’re also vulnerable to hacking:
In a less publicised incident last March, an American reconnaissance plane over South Korea suddenly returned to base on discovering that its GPS was being jammed, an imprudent move since it confirmed to the North Koreans the effectiveness of their methods.
Sadly, as the article concludes, the Air Force and its suppliers are tied together with lobbyists, and whether or not their unmanned aircraft actually work seems to be beside the point. Deptula argues now that the problem is that there’s still a “man in the loop”, the remote pilot who actually flies the drones (which, for all the hype, are still far from automated). This seems mildly insane to me, but then, the future will no doubt show which of us is right - but wait for the audit commission’s report rather than believing CNN.
(I very much enjoy my subscription to the LRB, despite being perpetually an issue behind in the physical edition. I’d heartily recommend one if you want to read the full post.)
