Despite the vivid images relayed by the Viking landers in the mid-1970s, Mars to most people remains a planet of the imagination, as unlikely a home for humans as it is for diminutive green men. To a surprising number of prominent scientists and politicians, however, it is the next...
There are more practical reasons for a joint mission. Neither nation alone can easily afford the estimated $40 billion price tag. And even that figure is conservative; it assumes the existence of the $10 billion orbiting U.S. space station, now scheduled for completion around 1992, which will be used as...
Technical cooperation might also ease the engineering difficulties inherent in a lengthy and complex manned voyage. At its closest point, Mars is 35 million miles from earth, or 160 times the distance of the moon. A hypothetical round trip, including a Mars layover, would take two to three years and...
Undaunted by these challenges, some space experts have already begun planning the Mars itinerary, devising a variety of baroque flight paths to save on energy and thus fuel. One trip, for example, would require a roundabout swing past Venus, which would lend the craft a gravitational boost in acceleration. On...
Safety, however, will be paramount in the minds of the crew. Collins will be commanding the shuttle's first ever nose-over-tail spin, so the tiled underbelly can be photographed by the International Space Station and checked for problems. After docking with the station, her team will conduct experimental...
