...Italy, following tougher laws passed in 2001, the number of Islamic terrorists arrested has climbed from 33 in 2001 to 64 in 2002 and 71 last year. But many prosecutions have been overzealous. In September 2002, 15 Pakistanis were arrested off the southern coast in a rusting cargo ship, charged with international terrorism and held in a local jail for more than nine months - before being released. In a notorious case last fall, an imam from Senegal who lived near Turin with his Italian wife and children was expelled as a "threat to state security" after he made a series...
...Pueblo was in international waters off North Korea when it was attacked by North Korean torpedo boats. Bucher and his men spent nearly a year in harsh captivity, before a negotiated settlement brought them home. A Navy court later recommended that Bucher be court-martialed for surrendering the ship without firing a shot, but the Navy secretary overruled the decision, saying the crew had suffered enough...
Once your Mars ship is poised in space--either hovering at Lagrange point L1 or fresh off the surface of the moon--your next worry is the matter of in-space propulsion. Speed is everything on the way to Mars, and not only because a seven-month trip in a confined space can be torturous. The bigger problem is that it can also be lethal because of radiation exposure in deep space, where the absence of Earth's magnetic field leaves astronauts far more exposed to deadly cosmic energy than they are in orbit...
...propulsion engines--in which a portable nuclear reactor heats charged gas and then fires it out the rear of the spacecraft--already exist and are capable of accelerating ships to very high speeds. But the stream of ions the engines produce is a thin one, and even a small ship requires a long time to accelerate--a problem when time is the very thing you're trying to limit. Another possibility is nuclear thermal propulsion, which uses a larger reactor to superheat traditional propellant and blast it out the engine nozzle. Things move a lot faster with such a system...
...with NASA's astronauts reduced to hitching rides on Soyuz modules, the private-rocket crowd is fired up because a privately funded ship might be ready for takeoff within a few years. Since 1996, several teams have been racing to develop a three-person spacecraft that could reach the edge of the atmosphere and repeat the feat within two weeks--the qualifications required to win the $10 million X Prize created by entrepreneur Peter Diamandis to encourage private spaceflight. Leading that race is legendary aerospace engineer Burt Rutan, who is gearing up for another test after his rocket plane broke...
