Purdue’s Stellar Reputation Advances Understanding of Stars, Planets, and Beyond

Purdue University isn’t just the Cradle of AstronautsHonoring decades of tradition, key discoveries from Purdue space scientists and engineers are advancing knowledge of the universe and missions to the moon or Mars.

James Webb Space Telescope images

Dan Milisavljevic is an astronomer and an expert on star explosions. An associate professor of physics and astronomy in Purdue’s College of Science, Milisavljevic (pronounced mili-sahv-la-vich) leads a project team studying images from the James Webb Space Telescope of Cassiopeia A, a star explosion that happened ten thousand years ago.

Living long-term on the moon or Mars

To help humans live on the moon or Mars, a Purdue experiment on the International Space Station is collecting the data needed to enable heat and air conditioning that can operate long term in reduced gravity and temperatures hundreds of degrees above or below what we experience on Earth. Issam Mudawar, Purdue’s Betty Ruth and Milton B. Hollander Family Professor of Mechanical Engineering, leads the project.

Spacecraft metals in Earth’s atmosphere

Dan Cziczo, a professor and head of the Department of Earth, Atmospheric, and Planetary Sciences in Purdue’s College of Science, was part of a team that discovered significant amounts of metals from spacecraft may be impacting Earth’s atmosphere and ozone layer. Cziczo is an expert in atmospheric science who has spent decades studying this rarefied region.

“Parking spots” in space

David Arnas, a Purdue assistant professor of aeronautics and astronautics, studies how to design “parking spots” for satellites to help prevent collisions and overcrowding both in areas closer to Earth, where many of these available locations have already been taken, and in other parts of space that will soon see an increase in satellite population, such as the large area between Earth and the moon called the cislunar region.

Bringing home asteroids

Michelle Thompson is a planetary scientist and expert in how asteroids, moons and other planetary bodies react with space — a process called space weathering. She is one of the first six humans — and the first woman — to analyze samples of asteroid Bennu brought to Earth by OSIRIS-REx. Thompson is an associate professor of earth, atmospheric, and planetary sciences in Purdue’s College of Science.

Space junk between Earth and the moon

To prevent spacecraft from running into each other, Purdue engineer Carolin Frueh is investigating how to observe and keep track of all human-made objects and predict the impact of their potential damage in near-Earth orbits and the cislunar region. Frueh is the university’s Harold DeGroff, Jr., Associate Professor of Aeronautics and Astronautics.
