...fact, such a directive already exists in some form - the international Outer Space Treaty of 1967, which governs the legal framework for activities in space. Best known for banning governments from putting nuclear weapons into orbit, the treaty also requires space-faring nations to avoid "harmful contamination" of other worlds while exploring the solar system. Human beings have yet to set foot on other planets, so the risk today comes from bacteria that can hitch a ride on unmanned spacecraft like NASA's Mars Phoenix Lander, which arrived on the red planet's surface last May.

...Asia since 4000 B.C. It is based on 12 temperaments represented by 12 symbolic animals - rat, ox, tiger, rabbit, dragon, snake, horse, sheep, monkey, rooster, dog and pig (the dragon being the well-known favorite). After 12 years, the cycle restarts, matching the length of Jupiter's solar orbit. (Read "China Not So Bullish About the Year...
...rovers were launched atop separate boosters. Spirit left Earth on June 10, 2003, and Opportunity followed on July 7, taking advantage of the biannual close approach Mars and Earth make as they orbit the sun. On solar system scales, a close approach is still a goodly distance - 35 million miles in 2003 - which means that the rovers needed seven months to get where they were going. Spirit landed first, bouncing down in a swaddle of air bags in Mars' Gusev Crater. Opportunity followed three weeks later, landing on the other side of the planet in what is now known...
...Lovell typed the instructions for the engine burn into the on-board computer, and the computer flashed back "99:40," which was code for "Are you sure?" Lovell hit the Proceed button. The engine lit and the burn worked exactly as scripted, inserting Apollo 8 into an initial lunar orbit 169.1 miles high at its peak and just 60.5 miles above the lunar craters at its nadir. Even before the crew re-emerged around the other side of the moon and back into radio contact with Houston, Anders snapped what is surely the most iconic photo of the space...
...crew circled the moon 10 times over the next 20 hours. On their final orbit, once again alone behind the moon, the crew re-lit the engine that was their only ticket home. If it had failed to burn, they would have been stranded forever in lunar orbit. The flight controllers - to say nothing of the families - waited anxiously for the astronauts to emerge from radio blackout. When they did, it was Lovell's voice that broke the silence...
