Single Room, Earth View

America's first woman in space describes the beauty of Earth from orbit.

Everyone I've met has a glittering, if vague, mental image of space travel. And naturally enough, people want to hear about it from an astronaut: “How did it feel?” “What did it look like?” “Were you scared?” Sometimes, the questions come from reporters, their pens poised and their recorders silently sucking in the words; sometimes, it’s wide-eyed, 10-year-old girls who want answers. I find a way to answer all of them, but it’s not easy.

Imagine trying to describe an airplane ride to someone who has never flown. An articulate traveler could describe the sights but would find it much harder to explain the difference in perspective provided by the new view from a greater distance, along with the feelings, impressions, and insights that go with that new perspective. And the difference is enormous: Space flight moves the traveler another giant step farther away. Eight and one-half thunderous minutes after launch, an astronaut is orbiting high above the Earth, suddenly able to watch typhoons form, volcanoes smolder, and meteors streak through the atmosphere below.

While flying over the Hawaiian Islands, several astronauts have marveled that the islands look just like they do on a map. When people first hear that, they wonder what should be so surprising about Hawaii looking the way it does in the atlas. Yet, to the astronauts it is an absolutely startling sensation: The islands really do look as if that part of the world has been carpeted with a big page torn out of Rand-McNally, and all we can do is try to convey the surreal quality of that scene.

In orbit, racing along at five miles per second, the space shuttle circles the Earth once every 90 minutes. I found that at this speed, unless I kept my nose pressed to the window, it was almost impossible to keep track of where we were at any given moment—the world below simply changes too fast. If I turned my concentration away for too long, even just to grab a camera, I could miss an entire land mass. It’s embarrassing to float up to a window, glance outside, and then have to ask a crewmate, “What continent is this?”

We could see smoke rising from fires that dotted the entire east coast of Africa, and in the same orbit only moments later, ice floes jostling for position in the Antarctic. We could see the Ganges River dumping its murky, sediment-laden water into the Indian Ocean and watch ominous hurricane clouds expanding and rising like biscuits in the oven of the Caribbean.

Mountain ranges, volcanoes, and river deltas appeared in salt-and-flour relief, all leading me to assume the role of a novice geologist. In such moments, it was easy to imagine the dynamic upheavals that created jutting mountain ranges and the internal wrenchings that created rifts and seas. I also became an instant believer in plate tectonics; India really is crashing into Asia, and Saudi Arabia and Egypt really are pulling apart, making the Red Sea wider. Even though their respective motion is really no more than mere inches a year, the view from overhead makes theory come alive.

Spectacular as the view is from 200 miles up, the Earth is not the awe-inspiring “blue marble” made famous by the photos from the moon. From space shuttle height, we can’t see the entire globe at a glance, but we can look down the entire boot of Italy, or up the East Coast of the United States from Cape Hatteras to Cape Cod. The panoramic view inspires an appreciation for the scale of some of nature’s phenomena. One day, as I scanned the sandy expanse of Northern Africa, I couldn’t find any of the familiar landmarks—colorful outcroppings of rock in Chad, irrigated patches of the Sahara. Then I realized they were obscured by a huge dust storm, a cloud of sand that enveloped the continent from Morocco to the Sudan.

Since the space shuttle flies fairly low (at least by orbital standards; it’s more than 22,000 miles lower than a typical TV satellite), we can make out both natural and human-made features in surprising detail. Familiar geographical features like San Francisco Bay, Long Island, and Lake Michigan are easy to recognize, as are many cities, bridges, and airports. The Great Wall of China is not the only manmade object visible from space.

The signatures of civilization are usually seen in straight lines (bridges or runways) or sharp delineations (abrupt transitions from desert to irrigated land, as in California's Imperial Valley). A modern city like New York doesn't leap from the canvas of its surroundings, but its straight piers and concrete runways catch the eye—and around them, the city materializes. I found Salina, Kansas by spotting its long runway amid the wheat fields near the city. Over Florida, I could see the launch pad at Cape Canaveral where we had begun our trip, and the landing strip, where we would eventually land.

Some of civilization's more unfortunate effects on the environment are also evident from orbit. Oil slicks glisten on the surface of the Persian Gulf, patches of pollution- damaged trees dot the forests of central Europe. Some cities look out of focus, and their colors muted, when viewed through a pollutant haze. Not surprisingly, the effects are more noticeable than they were the decade before.
