I've been obsessing over news about the Mars Curiosity rover ever since it touched down last month. One video, created by someone who worked on the project, captures some of the magic about what was done:
Did you notice some of the animations of the landing in that video? Did you notice how it was LOWERED ONTO THE SURFACE OF MARS WITH A CRANE FROM A ROCKET-POWERED PLATFORM?
Just watch the first few minutes. You'll be blown away.
I also think it's pretty cool that NASA has given Curiosity it's own voice via a Twitter account. This is a great way to more easily connect with those who might be interested in learning more about space exploration.
Finally, there's a really good "Ask Me Anything" on Reddit with a bunch of the engineers from the Curiosity project. The Reddit audience is perfect for this sort of thing, asking a combination of human-interest questions and highly technical questions and making for a better read than anything else on the subject.
