In the schematic drawing on page 7A of the Nov. 8 Journal-World, it indicates that Voyager II was launched on Aug. 20, 1977, and Voyager I was launched on Sept. 5, 1977. Was Voyager II really launched before Voyager I?

According to the NASA Web site, Voyager II launched 16 days before Voyager I, which flew on a faster, shorter trajectory to Jupiter. Both were launched from Cape Canaveral, Fla., aboard Titan-Centaur rockets. Together they have explored Jupiter, Saturn, Uranus and Neptune, as well as 48 of the planets' moons and their rings.

On Nov. 5, Voyager I was about 8.4 billion miles from the sun, which some scientists argue is the edge of our solar system.
