Greetings from Earth
Wednesday, April 27th, 2005In 1977, Voyagers 1 and 2 were launched from the Kennedy Space Flight Center in Florida. Twenty-seven years later, the spacecrafts are currently more than 90 A.U. — that’s 8.4 billion miles, for all you English majors — away from Earth, and have become the most distant human-made objects in the universe.
Let me pause for just a moment to mull over how amazing that is. It’s been 27 years, and these things are still hurtling through space at an average of 36,600 miles per hour. The batteries in my digital camera don’t last for more than three hours, but somehow these giant toaster ovens have enough juice to travel and send data back to us until 2020. Now past Neptune, the crafts are steadily approaching the edge of the solar system. In 40,000 years, Voyager 1 will pass another star. Clearly, it’s only a matter of time — albeit a very, very long time — before it crashes into some distant planet, denting the roof of an alien trailer home.
NASA has, of course, gone to great lengths to prepare for such an occasion. Mounted upon each Voyager is a copy of The Golden Record, a sort of AAA guidebook to Earth that was designed by a committee chaired by late Cornell astronomy and space sciences professor Carl Sagan. The Golden Record is perhaps humankind’s most impressive feat of conciseness, condensing what is supposed to be a portrayal of “the diversity of life and culture on Earth” into a 12-inch, two-sided disc.
