NASA has so far provided $30 million to build the Harvard ultra-violet experiment and to process the results.
No one knows exactly how long OSO-VI and its Harvard experiment will continue to operate. OSO satellites are designed to last six months, but one earlier OSO has been working for nearly two years.
The Harvard experiment is contained in a 40-inch box that is open at one end. The box is plated with gold to distribute heat evenly. A cluster of 13 light detectors-much like the electric eye on a camera-keeps the box pointed at the sun. A small telescope...
The visible light region of this spectrum would show up as color bands, but the invisible ultra-violet rays can be detected only by a special electric tube. In the experiment, this tube acts like a television camera, converting the ultra-violet rays to electric impulses that are transmitted to...
So far the best explanation for the OSO-IV failure is that a small bubble of gas was trapped in a plastic coating that surrounds the transformer's wire coils. As the gas slowly leaked out it caused a surge of electric current that burnt out the experiment's electric...
