Iris: Carnegie Mellon's Pioneering Student-Built Moon Rover

In a remarkable display of ingenuity and ambition, a team of students from Carnegie Mellon University has embarked on a mission to send a tiny robotic rover to the lunar surface. Named Iris, this shoebox-sized rover represents a significant milestone in the democratization of space exploration, proving that groundbreaking achievements are no longer exclusively reserved for large space agencies or deep-pocketed corporations.

Weighing just 2 kilograms and standing about the size of a small pizza, Iris may be diminutive by space rover standards, but the project itself is a testament to the boundless potential of student-driven innovation. Since its inception in 2017, an estimated 300 students have collectively dedicated the equivalent of a century's worth of work-hours to bring this lunar rover to life.

"There were no constraints—just come in at 2 kilograms or less!" laughs Raewyn Duvall, the program manager for the Iris rover and a research associate at Carnegie Mellon. Despite its modest size, the development of Iris has been a complex undertaking, requiring meticulous attention to detail and a willingness to embrace calculated risks.

Iris is slated to hitch a ride on the Peregrine lunar lander, built by Astrobotic Technology, a Pittsburgh-based company spun off from Carnegie Mellon University. If all goes according to plan, the Peregrine Mission One will be launched to the Gruithuisen Domes region in the moon's northern hemisphere by the Vulcan Centaur rocket, a new and powerful booster developed by the United Launch Alliance.

While the launch date remains uncertain due to delays caused by COVID-19 and technical challenges, the Iris team has seized the opportunity to fine-tune their creation, ensuring that every aspect of the rover is meticulously prepared for its lunar adventure.

At the heart of the Iris project is William L. "Red" Whittaker, a renowned professor of robotics at Carnegie Mellon and a driving force behind the university's space initiatives. Whittaker, who is also a co-founder of Astrobotic, emphasizes the significance of this mission, stating, "In space, what counts is what flies."

The Iris rover is a testament to the ingenuity of its creators, who have masterfully engineered a compact and efficient design within the constraints of a 2-kilogram weight limit. Powered by lithium-ion batteries and equipped with a skid-steer system for maneuverability, Iris is expected to operate for up to 50 hours on the lunar surface, capturing images and relaying data back to Earth via the Peregrine lander's wireless network.

While the rover's lifespan and range may be limited, its successful deployment and operation would mark a groundbreaking achievement, demonstrating that lunar exploration is within reach for even modest university-based projects. As Duvall aptly puts it, "Everything that happens is going to be—wow, we did it!"

Through the Iris project, Carnegie Mellon University and its talented student team are paving the way for a new era of democratized space exploration, where innovation and determination transcend the boundaries of traditional space programs. With each successful step, Iris brings us closer to a future where the celestial frontier is accessible to all, inspiring generations of aspiring scientists and engineers to reach for the stars.
