I was reading an article in this month's issue of Scientific American magazine on the future of space exploration. The article featured a map that showed the positions of the space probes Voyager 1, Voyager 2, Pioneer 10, and Pioneer 11 in our solar system. The web site Heavens Above keeps track of the current positions of the probes.
It just absolutely amazes me how far these probes have travelled. When you look at the map, you can see that Voyager 1 is farther from Pluto than Pluto is from our own sun. Achievements such as Voyager 1 are an example of what humanity can accomplish if we could put aside our differences and focus our energy and efforts on exploring the universe in which we live.
To find out more about Voyager 1 and the other probes mentioned above, check out the Missions page for the Jet Propulsion Laboratories. You can watch a short film about the Voyager probes on the JPL's site here.
