A Venus Chamber on Earth

By May, the National Aeronautics and Space Administration should be able to re-create the ferocious atmosphere of Venus—in Cleveland.

No probe built today could survive on Venus for more than a couple of hours, which is precisely the problem that the Extreme Environment Test Chamber at the Glenn Research Center is designed to solve. The cylindrical chamber, 4 feet long and 3 feet in diameter, will simulate the Venusian atmosphere, complete with 1,300 pounds per square inch of pressure, temperatures of 900 degrees Fahrenheit and hydrofluoric acid. The chamber will have a stainless-steel shell, up to 10 inches thick, and its acidic atmosphere will require the regular replacement of its lining, which is made from a nickel-chromium alloy. A peephole made of processed sapphire will allow sensors to take spectrographic readings.
