Space scientists are the boots on the ground of space exploration, and Purdue’s researchers are among the most elite.
Celebrate the wonder of space with this collection of the most recent and impactful news from Purdue University’s space research labs. 
Icy impacts: Gauging thickness of ice on Europa brings science closer to finding possibility of life
Europa, one of Jupiter’s rocky moons, is home to huge saltwater oceans and thought to be a potential home to nonterrestrial life — but this search for life is dependent on scientists knowing the depth of the icy shell encasing Europa’s entire surface.  
Brandon Johnson’s lab has been able to determine the depth of that shell using his expertise in crater modeling.

Rover captures a Martian eclipse. Perseverance team lead at Purdue explains
The Perseverance rover recently captured images of a solar eclipse on Mars. In this video, Briony Horgan explains the science behind eclipses on Mars, Earth and other planets — and why Earth’s eclipses are particularly special.

Alexandria Johnson’s expertise in cloud physics provides vital information to many fields, from the way microplastics are affecting weather patterns to the study of faraway exoplanets.
After the most powerful telescopes have reached across the universe, sometimes Johnson’s ability to parse an exoplanet’s own densely clouded sky is the best way to see what’s happening on the farthest of these celestial bodies.
“If we want to understand these enshrouded exoplanets, we need to understand the clouds. That understanding gives us insights into the atmospheric chemistry at work, atmospheric circulations and the climate of these exoplanets,” Johnson says.

Purdue University is proud to be the Cradle of Astronauts and to showcase its wide-ranging and historic relationship with space exploration on the Purdue in Space hub. 

For two-week terms, teams commit to living in a compact habitat in Utah’s remote red dust desert — conserving their resources and conducting research designed to address real-life situations that future missions to Mars may face.
“To have something like MDRS, where you’re actually getting exposure to practical problems that some space missions would face, is a phenomenal opportunity,” says Jesus Meza Galvan, a PhD student in aerospace engineering.
