...drive through the Martian countryside should begin this Friday, July 4. At about 10 a.m. Pacific time, after a seven-month journey, NASA's Pathfinder spacecraft will deposit the robot car--dubbed Sojourner--on the Martian surface, marking the first time an American spacecraft has kicked up the Martian soil since the Viking landings in 1976. More important, it will be the first time that NASA has been able to move an unmanned vehicle from place to place on a foreign world. "I truly believe," says project scientist Matthew Golombek, "that Pathfinder will change our view of Mars...
Before the little rover can traverse the Martian surface, of course, it must reach the Martian surface, and that won't be easy. The 1,300-lb. spacecraft will slam into the planet's atmosphere at 16,300 m.p.h., ultimately causing it to experience deceleration forces of 20 Gs. The vehicle's cork-and-silicon aeroshell should absorb most of this body blow. Both a parachute and a retrorocket will slow its plunge, and an array of airbags will inflate to cushion the shock of landing. And finally, the spacecraft will simply drop to the surface, striking the ground like...
PASADENA, Calif: After a lull of more than 20 years, NASA is poised to resume exploration of the Red Planet as the Mars Pathfinder spacecraft prepares for a July 4 touchdown. Making a whimsical entry, the half-ton lander will approach the surface at 1pm EST at about 55 miles per hour, whereupon a bubble pack will absorb the brunt of the impact, sending the lander bouncing like a basketball up to the height of a four-story building until it settles safely on the planet surface. A small rover named Sojourner (24.5 inches long by 18.7 inches wide) will...
...state visit to Ireland, said the following during a speech in Belfast: "I got a letter from 13-year-old Ryan from Belfast. Now, Ryan, if you're out in the crowd tonight, here's the answer to your question. No, as far as I know, an alien spacecraft did not crash in Roswell, New Mexico, in 1947. [Pause for laughter, according to an official transcript.] And, Ryan, if the United States Air Force did recover alien bodies, they didn't tell me about it either, and I want to know. [Applause.]" UFOlogists will tell you bitterly about...
...finally explained, we can return to the question of what really happened at Roswell. According to which experts one chooses to believe: there may have been more than one crash site; the U.S. government may have recovered dead aliens (the number varies) as well as a salvageable spacecraft; the craft may have been a secret government prototype and the dead aliens may have been test chimps with their fur eerily singed off or, as Popular Mechanics hypothesizes this month, imported Japanese pilots who had been flying similar experimental craft during the war; then again, the wreckage may really have been...
