NASA selects Purdue for new institute researching space habitats

Posted Apr 9, 2019

NASA announced Shirley Dyke will lead the new Resilient ExtraTerrestrial Habitats institute, to be located in West Lafayette. Dyke is a professor of mechanical and civil engineering with a degree in aeronautical and astronautical engineering.

"This is an exciting opportunity for the RETHi research team to play a role in shaping the future smart space habitats," Dyke said. "Developing resilient space habitats continues Purdue's legacy of leadership and collaboration in science, engineering and space exploration."

The institute will receive as much as $15 million over a five-year period from NASA's Space Technology Mission Directorate. RETHi is a multi-disciplinary partnership with the University of Connecticut, Harvard University and the University of Texas at San Antonio.



Image-based Reconstruction of Virtual Lava Tube

A team consisting of Jongseong Choi, Anahita Modiriasari, and Audai Theinat have reconstructed a virtual model of a Lava Tube, reconstructed using high-quality images and video, to learn the formation and structural characteristics remotely, process and analyze highly focused areas, and decipher useful information for potential extraterrestrial habitats.

Potential Human Habitat Located on the Moon

Radar data confirmed a previously theorized enormous cavern called a lava tube in the Marius Hills region of the moon. Space suits alone can’t shield astronauts from its elements: extreme temperature variation, radiation, and meteorite impacts; unlike Earth, the moon has no atmosphere or magnetic field to protects its inhabitants. This finding could enable astronauts to make longer expeditions to the moon or even provide shelter for a moon colony. According to Jay Melosh, Distinguished Professor of Earth, Atmospheric and Planetary Sciences at Purdue, the lava tube near the Marius Hills is spacious enough to house one of the United States’ largest cities.
