...ion engine is far more economical. With electricity generated by solar panels, it strips electrons off the atoms of vaporized mercury passing through a coffee-can-like chamber, converting them to ions. Expelled at high speeds in a focused beam, the charged particles act like a rocket exhaust, propelling the craft forward. Though its thrust is minuscule and far too feeble to lift payloads from the earth, the ion engine performs efficiently in the vacuum of space. It can function for years because it draws on solar energy and uses fuel sparingly. It can be stopped and restarted countless times...
...Congress provides the needed funding, the probe will be carried into earth orbit by the space shuttle in the summer of 1985. Boosted by a conventional rocket, it will fly off toward the comet, gradually accelerated by its cluster of six or eight small ion engines, during the four-month journey. On command from earth, it will drop a small instrument-packed probe provided by the European Space Agency directly into the comet's head, which scientists believe is made up of icy debris and a smattering of organic molecules. Because comets have probably changed little since they were...

He has not done that thus far and has forced the University in the form of the ACSR to sort of duplicate a great deal of what has gone on, and I will describe that briefly...
