"What do you do with a 1,000-foot wreck that's full of fuel and half-submerged on a rocky ledge in the middle of an Italian marine sanctuary? Remove it. Very carefully. Stuck on a rocky shoal off the Tuscan island of Giglio, leaving the wreck where it is probably isn't an option but removing a massive ship that's run hard aground and incurred major damage to the hullinvolves logistical and environmental issues that are just as large. First there's the fuel. A half a million gallons of fuel could wreak havoc on the marine ecosystem — the ship is smack in the middle of the Pelagos Sanctuary for Mediterranean Marine Mammals. Engineers may need to go in from the side using a special drill to cut through the fuel tanks in a process called hot tapping. 'You fasten a flange with a valve on it, you drill through, access the tank, pull the drill back out, close the valve, and then attach a pumping apparatus to that,' says Tim Beaver, president of the American Salvage Association. 'It's a difficult task, but it's doable.' Then if it's determined that the Costa Concordia can be saved, engineers could try to refloat the ship and tug it back to dry dock for refurbishing. The job will likely require 'a combination of barges equipped with winches and cranes' to pull the cruise liner off its side then once the Concordia is off the rocks, 'they are going to have to fight to keep it afloat, just like you would a battle-damaged ship.' Another alternative is to cut the vessel into smaller, manageable parts using a giant cutting wire coated with a material as hard as diamonds called a cheese wire in a method was used to dismember the 55,000-ton Norwegian-flagged MV Tricolor. Regardless of how the Concordia is removed, it's going to be a difficult, expensive and drawn-out process. 'I don't see it taking much less than a year, and I think it could take longer,' says Bob Umbdenstock, director of planning at Resolve Marine Group."
"The Sprite project is testing the feasibility of chip-sized spacecraft. 'Rather than hand building one-of-a-kind spacecraft, we envision constructing spacecraft on wafers in much the same way that common integrated circuits are made today. During fabrication, solar cells and other components would be incorporated with microelectromechanical systems techniques. Instead of exhaustively testing each part, as is done with current spacecraft, engineers will be able to monitor Sprite quality in a less labor-intensive fashion by using statistical process control, testing a few chips from each batch to make sure they meet specifications.' The project's goal is to deploy true 'smart dust,' comprised of 5- to 50-mg single-sensor spacecraft capable of forming deep-space sensor arrays."
"Ever wanted to launch your own satellite into space? Thanks to a project at the Cornell Space Science Lab, now you can. In the words of the grad student leading the project, Zac Manchester, 'What better way of showing off your uber-geek credentials than having your own spacecraft?' Zac hopes that by shrinking the size of each spacecraft and using advancements in computer and solar cell technology, satellites can follow the path of the personal computer revolution, opening up space for the masses. For small donations you will receive mementos, but for $300 and up you will get your very own satellite to be launched into space.
