Something very exciting happened this week: Spaceflight became routine.

Remember just a couple of years ago? The press was full of flopniks, grapefruit-sized spacecraft, and about a launch every other month. Every mission was an adventure, and space was the great unknown.

All that has changed. Not only are we launching more, and more advanced scientific satellites, but we are launching satellite systems. Only two months ago, the Navy launched the first of the Transit satellites. These satellites allow a ground-based observer to determine one's location to a fair degree of accuracy. But since there's no guarantee any one satellite will be overhead at a given time, you need a constellation of Transits.

Number two was launched last week on June 22. The age of reliable space utilization has dawned.
