...fact that for those on the inside, the "outdoor spaces" are going to seem rather full of the center's Georgian red brick neighbors. As for Le Corbusier's famous concrete sunbreakers, one professor thinks that they show "a fantastically optimistic opinion of the amount of sunlight there is in Cambridge." And finally, since the asymmetrical building is wrapped around symmetrically spaced pilotis, the structural columns are apt to rise any old place in any given room. But if Harvard has its doubts as to whether the center will ever work smoothly, it does not doubt that this...
Ranging far out into the solar system, unmanned spacecraft will feel at home in vacuum, be unbothered by radiation, take advantage of weightlessness, get their energy from sunlight as green plants do on Earth. They will perform elaborate maneuvers in response to orders built into their brains, like the instincts of insects, which lead thoroughly successful lives without a trace of reason. Sometimes they will listen with sensitive radio ears for whispers of command from millions or hundreds of millions of miles away. Some of them will send tough-skinned projectiles down into hostile atmosphere and record what they report...
...must plot celestial courses, and enormous vacuum chambers are needed to test behavior in simulated space. These strange space creatures are almost a new type of life, comparable in zoological terms to the first venturesome animals that crawled out of sea water and learned to live in air and sunlight. To breed them calls for the talents of many branches of science...
When the spacecraft passes beyond Earth's atmosphere, its real life begins. The shroud around it falls away; there is no air now to do damage. Gravity has fallen to zero, and frail antennae and solar panels can swing outward, pushed by feeble springs. The spacecraft absorbs sunlight, as a baby breathes air, and electrical energy pulses through its metal circulatory system. It is now a denizen of space...
...each object in space assumes a temperature that depends on the balance between the radiation that it absorbs and the radiation that it emits. A dab of paint (if it stays in place) can spell the difference between cold and hot. So can a shiny part that reflects sunlight to a light-absorbent part. Keeping all parts at proper temperatures is one of the hardest jobs in designing a viable spacecraft...
