...last week's mass moon watch, the professionals needed the dilettantes badly. When Aldebaran slipped behind the moon, it never slipped completely. Rather, it just arced around a bit of horizon, seeming to flicker as it passed behind mountains and peeked over valleys. The pattern of flashes allows astronomers to trace the lunar profile, refining surveys taken by past space probes. Since observers on different parts of the earth would see the star obscured by different parts of the moon, however, the more sightings scientists collected, the more lunar real estate they would cover...
...floor other than the one she has selected...who stands a substantial distance from her, is not likely to hurt her without giving some signal." If she'd read his book, she would have been able to unclench. That is, until the next human appeared on the horizon...
...Mars, Pathfinder had conducted dozens of worthy science experiments, had begun to challenge at least one long-held perception about the red planet and had transmitted more than 1,700 photos of the landscape, many of which were incorporated into a "monster pan," a spectacular 360[degrees], three-dimensional, horizon-to-horizon mosaic image that, when viewed through 3-D glasses, is almost as good as being there. The mission had also achieved a historic first on Mars: a motor-vehicle accident...
...rover, the engineers had rehearsed a fairly straightforward maneuver that called for Pathfinder to raise one petal, tilting the entire craft 45[degrees], retract the deflated bag further and then lower the petal. The signal to execute the maneuver was sent up shortly before Earth set over the Martian horizon, breaking the communications link until dawn; just before the connection was actually severed, a picture came back confirming that the command had been executed. Though a portion of the bag still blocked part of the petal, there was probably enough room for Sojourner to slip...
...focus of these missions, said Gore, is Earth--how to live and survive here better. As Pathfinder and subsequent missions unfold, he said, "we are likely to experience an emotional and spiritual impact not unlike the one which accompanied that first picture of Earth rising from the moon's horizon a generation...
