The trans-Atlantic eclipse voyage was organized by Betchart Expeditions ( 252-4910, http://www.betchartexpeditions.com ), a California-based company specializing in science-oriented travel. It offers about two dozen science-themed trips a year to destinations around the globe. I'd traveled with Betchart once before, on a trip to Antarctica 20 years earlier, and I trusted the company, the intellectually oriented clientele its trips attract and the experts it chooses for daily lectures.

The day in 1492 when Columbus ran into a cluster of islands blocking his way to India is celebrated throughout Latin America and in Spain. It is now fixed in the United States as the second Monday in October, and Americans too have long commemorated the event, both embracing and vilifying the explorer. Irish and Italian immigrants proudly pointed to Columbus' Roman Catholic religion to fight the prejudice they experienced in their adopted country, and in 1882, they founded the Knights of Columbus, now the world's largest Catholic service organization.

Re "NASA confirms Voyager milestone," Sept. 13 Iread of Voyager 1 leaving our solar system with more excitement, pride and soaring emotion than I had expected. I'm a retired teacher, and I remember the excitement that Voyager 1 stirred when it was launched in 1977. It was proof of American ingenuity, a measure of our national resolve to be first in everything we tried to accomplish. My students' imaginations were fired up by America's achievements in space. In fact, two of them went on to earn seats on space shuttle missions.

You can't spot Voyager 1 as it leaves the solar system's heliosphere, but the National Radio Astronomy Observatory can, and did it just for kicks. Well maybe not for kicks, but scientists were interested in how well their array of 10 radio telescopes, stretching from Hawaii to St. Croix, Virgin Islands, could plot the spacecraft, which is more than 11 billion miles from Earth. Usually, those instruments home in on the faint radio signals from quasars, black holes and the like. They also routinely track NASA's Cassini spacecraft, out around Saturn.

After 36 years of space travel and months of heated debate among scientists, NASA confirmed Thursday that Voyager 1 has indeed left our solar system and had entered interstellar space more than a year ago. "Voyager has boldly gone where no probe has gone before, marking one of the most significant technological achievements in the annals of the history of science," said John Grunsfeld, NASA's associate administrator for the Science Mission Directorate....
