Recreating the environment that most spacecraft experience on their missions is difficult on Earth. Many times it involves large vacuum chambers or wind tunnels that are specially designed for certain kinds of tests. But sometimes, engineers get to just do larger scale versions of the things they got to do in high school. That is the case for a recent test of ExoMarss parachute system. A team of ESA engineers and their contractors performed a scaled up egg-drop test common in physics classes across the world. Except this one involved a stratospheric balloon the size of a football field and a helicopter.

Scientists have created the largest catalogue of exploding stars ever assembled, and it's telling us something surprising about the mysterious force driving our universe apart. After analyzing over 2,000 stellar explosions spanning billions of years, researchers have found hints that dark energy, the force making up 70% of our universe, may not be the constant we once thought. Instead, it appears to be changing over time, potentially even weakening!
