Strange but True: Curiosity's Sky Crane

Source - NASA Science News for July 31, 2012

How do you deposit a massive SUV-sized nuclear-powered rover to the surface of an alien planet without making an SUV-sized crater? NASA's solution for Curiosity will be attempted for the first time on August 5/6 when they gently lower the rover to the red sands of Mars using a Sky Crane.

Big Picture Science - Skeptic Check: Follywood Science

The Day After. 2001. Prometheus. There are sci-fi films a’plenty … but how much science is in the fiction? We take the fact checkers to Hollywood to investigate the science behind everything from space travel to human cloning.

Plus, guess what sci-fi film is the most scientifically accurate (hint: we’ve already mentioned it). Also, why messing with medical facts on film can be dangerous … and the inside scoop from a writer of one of television’s most successful sci-fi franchises.

And, a robot who surpasses even Tinseltown’s lively imagination: a humanoid that may become a surrogate you.

Big Picture Science - Olympics for the Rest of Us

Let the games begin! The mad dash to the phone … the sudden spring out of bed … the frantic juggling of car keys, grocery bags and a cell phone! Olympic athletes may have remarkable speed and strength, but it’s easy praise the extraordinary. Here’s to the extreme averageness of the rest of us. From beer bellies to aching backs, we’re all winners in the Darwinian Olympics just by virtue of being here.

Identify the one physical trait that you share with all Olympians – your head – and why it’s a remarkable human evolutionary achievement. Plus, the role of genes in putting on the pounds … and what event Spiderman would enter to win the gold.

X-FLARE: For days, giant sunspot AR1515 has looked capable of producing a really strong explosion. On July 6th it finally did. Yesterday, the sunspot's magnetic canopy erupted, producing a brief but potent X1.1-class solar flare. The explosion hurled a CME into space and sparked a solar proton storm around Earth.  Check http://spaceweather.com for images and updates.
