Getting Down and Dirty with Curiosity's Sampling System
By Qualification Model Dirty Testing Team

Before Curiosity does any sampling on Mars, people here on Earth have to get down and dirty, literally! The Qualification Model Dirty Testing team tests Curiosity's Sampling System with a replica of the hardware here on Earth in a Mars-like chamber. This often involves moving large rocks, hauling dirt, drilling into rocks and scooping up soil.

Snapping a Picture of Curiosity's Landing
By Sarah Milkovich

If you've ever taken a picture out the window of a moving car, you know that some portions of the picture are crisp and in-focus but due to the motion of the car, others are blurred. When we were called to take a once-in-a-lifetime image of Curiosity's landing, the HiRISE team needed to make sure that picture of the rover was crisp even if the background surface was blurry. No pressure!
