Astronomy and Space Program Links

We have entered an age only dreamed about just a few short years ago.
Probes from NASA, ESA - European Space Agency, Russia and Japan are
exploring the Moon, Mars, asteroids and comets and the outer Solar System with a fleet of probes and robots. The Mars Rovers Spirit and Opportunity
landing in January of 2004, have now surpassed an entire Martian year as of November 2005, well beyond their original 3 month mission. They have now experienced all of what Mars has to offer as seasons. A new Mars
orbiter is on its way, as is a new similar expedition to the planet Venus.
I encourage you to Explore on your own some of the great sites covering what Space Programs around the world are accomplishing.
The links here are just an introduction to what you can find.
They just happen to be some of my favorites.
