Two years ago today, at 10:32 p.m. PDT, NASA successfully landed its Curiosity rover on Mars. At the time, NASA Administrator Charles Bolden heralded the landing as "an amazing achievement."
"Today, the wheels of Curiosity have begun to blaze the trail for human footprints on Mars. Curiosity, the most sophisticated rover ever built, is now on the surface of the Red Planet, where it will seek to answer age-old questions about whether life ever existed on Mars -- or if the planet can sustain life in the future."
After landing safely, Curiosity sent its first tweet (and photo!) back to Earth:
In just a few years, the Mars 2020 rover will take Red Planet exploration to the next level as it brings high-tech tools -- like the science fiction-esque ability to make oxygen in a carbon dioxide atmosphere -- to space.
