...tube is a strong-walled metal pipe, a few inches in diameter, from which the air can be pumped. At one end, a section is walled off by a copper diaphragm: that section is filled with an explosive mixture of oxygen and hydrogen. At the other end is a vacuum tank, and just ahead of it is a tiny nose-cone test model. When an electric spark explodes the oxygen-hydrogen, it bursts through the diaphragm and into the vacuum. Ahead of it rushes a hot shock wave that hits the test model at actual re-entry speed and temperature...

But in the vacuum of space, it was enough to push Vanguard I a mile or so off course over a period of two years. Light pressure is important in astronomy; it forms the tails of comets and is probably responsible for distributing the debris of exploded stars throughout the galaxy. But not until Vanguard I had been...
