That, in any case, is what the prevailing thinking has been. Now, however, it appears that thinking may be wrong. Last week NASA released a flurry of new images from the Mars Global Surveyor spacecraft that suggest that even today, water may be flowing up from the Martian innards and...
Finding liquid water on Mars' surface has never been easy--mostly because it simply can't exist there. The modern-day Martian atmosphere has barely 1% the density of Earth's, and the planet's average temperature hovers around a paralyzing -67[degrees]F. In an environment as harsh as...
In the coming years, high tech will increasingly look low tech as we solve problems by turning to biology and microscopic particles where we once turned to engineering and information technologies. Today a rig churning and cranking to sop up an oil spill mars an ocean landscape; tomorrow genetically engineered...
Nobody wants to leave the planet a red, barren dust bowl like Mars, incapable of sustaining any life except the hardiest surviving lineages. But unless we anticipate the impact of technologies--before they are practical--it will be impossible for us to apply them thoughtfully, fruitfully and respectfully, or to...
