Riding Rockets - Mike Mullane [211]
The real joy of my new position was the illusion it created. I could put my head so far forward that the shuttle’s structure disappeared behind me. My view of Earth was completely unobstructed. It brought back memories of snorkeling in the Aegean Sea and watching the undersea life through my face mask. As I had then, I now had a powerful sense of being part of the element in which I was immersed, not a foreign visitor. When I steadied myself with my fingertips and then pulled those away, I would momentarily float free of any contact withAtlantis, enhancing the sensation of being a creature of space, not an astronaut locked in a machine.
To the strings of Beethoven’s “Ode to Joy” I watched my planet silently move under me. But this time I was seeing it as never before. Not only was our orbit steeply tilted to the equator, we were also in one of the lowest orbits ever flown by a space shuttle. We were scarcely 130 statute miles above the Earth, approximately the distance from New York City to the eastern tip of Long Island, or Los Angeles to San Deigo. At this altitude the planet was hugely close and there were new details of its earth, sea, and sky to thrill me.
I could see the patina of the Earth’s oceans. The wind-rumpled water gave them the texture of an orange rind, but in colors that varied with the angle at which the Sun stuck them. At high sun, the open seas were Crayola blue. At grazing angles, they reflected tones of gray and silver and copper. In places of exceptional water clarity, like the Caribbean, the dunelike humps and valleys of the seafloor were clearly visible, their white sand diluting the ocean blue to yield a striking turquoise. In the sheen of the Sun I could see evidence of the dynamics of the sea. There were circular eddies similar to the low-pressure-cloud swirls in the atmosphere. Boundaries between currents appeared as dark lines. Currents past headlands would create noticeably different downstream wave patterns, exactly like the ones I could see in clouds downstream from mountain ranges. In Persian Gulf anchorages I could make out the “dots” of supertankers and occasionally, in the glint of the Sun, I would catch sight of the V-shaped wake of one of these monsters under way. Later, asAtlantis was on the descending portion of an orbit deep into the southern hemisphere, I watched the miles-long bluish-green ribbon of a bloom of plankton. We had been told to expect to see these in the fertile waters approaching Antarctica. Farther south, a flotilla of icebergs sailed on currents like so many ships of the line.
At the southern limit of her orbit,Atlantis ’s nadir came within three hundred miles of the coast of the Antarctic continent, now in late summer. I pulled a pair of gyroscopically stabilized binoculars from their Velcro anchor and peered southward. The pole was nearly 1,800 miles distant, so I had no view of it. Instead, I focused on the rugged coastal mountain chains. The occasional black of a windswept cliff was the only color in an otherwise sheet-white topography.
Atlantiscurved northward and began her 12,000-mile fall toward the opposite end of the Earth. It was a remarkable physics that kept me on this godly merry-go-round. We were literally falling. Just as a thrown ball falls in a curve,Atlantis was on a curving trajectory to impact Earth. But impact
