The Space and Terrestrial Robotic Exploration (SpaceTREx) Laboratory at University of Arizona's Aerospace and Mechanical Engineering Department develop systems engineering design and control solutions for space, planetary and asteroid exploration, using small spacecraft, robots and sensor network devices. Research is focused on developing enabling technologies for extreme environment exploration, interplanetary CubeSat explorers and on-orbit servicing spanning spacecraft constellations, propulsion, power and communications.
The laboratory and key personnel have a diverse range of expertise including CubeSat design, development, launch expertise, smart system design and control using bio-inspired and neural network control paradigms, space weather and extreme-environment robotics. The laboratory is rapidly expanding and diversifying its research portfolio by exploiting new developments in terrestrial technology, particularly nanotechnology and applying it to space exploration, while taking technology developed for space and applying it towards important challenges facing humanity in the fields of climate change, security, water and energy.
Interdisciplinary Expertise in Engineering, Science and Exploration



Professor Jekan Thanga is an Associate Professor of Aerospace and Mechanical Engineering and Electrical and Computer Engineering at the University of Arizona, where he leads the Space and Terrestrial Robotic Exploration (SpaceTREx) Laboratory and the NASA-supported ASTEROIDS Laboratory. An Associate Fellow of the AIAA, his research develops autonomous robotic infrastructure for the exploration, construction, and long-term sustainability of the Moon, asteroids, and other planetary bodies. Professor Thanga earned his Bachelor's degree in Engineering Science (Aerospace) and his Ph.D. in Space Robotics from the University of Toronto Institute for Aerospace Studies (UTIAS), followed by postdoctoral research at MIT's Field and Space Robotics Laboratory (FSRL). Prior to academia, he contributed to the Canadarm, Canadarm2, and DARPA Orbital Express space robotics programs at MDA Space Missions. His research spans autonomous lunar infrastructure, robotic construction, in-situ resource utilization (ISRU), spacecraft swarms, machine learning, artificial intelligence, modular space systems, and resilient robotics for extreme environments, with applications extending to mining, disaster response, and critical infrastructure on Earth. Professor Thanga has secured more than $17 million in competitive research funding, authored more than 250 peer-reviewed publications, trained over 300 students, and received numerous national and international honors, including the Popular Mechanics Breakthrough Award and multiple NASA and Best Paper awards. In recognition of his contributions to space robotics, asteroid exploration, and STEM education, the International Astronomical Union named Minor Planet (20406) JekanThanga in his honor.


Professor Asphaug studies planet and satellite formation, including giant impacts such as that which formed the Moon. The ensuing diversity of planets is the subject of his book When the Earth Had Two Moons (HarperCollins, 2019). He also studies "small bodies" (asteroids, comets and satellites) that are leftovers of accretion, working to understand their formation and evolution, low-gravity geology, and activity and surface patterns. He participates in laboratory research looking into the strength properties of meteorites, and theoretical research into the origin of chondrules. Over the years, thanks to motivated students, he has also explored crater lakes and patterned ground on Mars, the delivery of volatiles to the lunar surface, and bombardment of Saturn's rings. He was on the Galileo and LCROSS missions, and is on the science teams of upcoming missions to asteroids Psyche and Didymos, and to the Martian moons. He leads the Comet Radar Explorer (CORE) mission concept, proposed twice to NASA Discovery, to obtain a high definition medical-like scan of a comet nucleus interior, and is helping to develop an instrument that would make seismic imaging of small body interiors a remote-sensing investigation. In SpaceTREx he is helping to develop innovative low cost approaches to exploration, and the AOSAT cubesat centrifuge that will mimic the low but non-zero gravity of asteroids.
