We are first and foremost a business. We aim to extract resources from asteroids to boost the Earth's economy and kick start the Space Based Economy as the vast values of some asteroids can be valued in trillions, with the largest asteroids being worth quintillions, while even small asteroids can be hugely valuable. This money will be spent in building ever growing amounts of space infrastructure so that we can eventually allow all humans who desire it to live and work in Space.Our team is currently working in partnership with the Space Robotics Lab at Tohoku University, Japan, developing SCAR-E. These low-cost, ruggedised, walking and climbing robots will be capable of undertaking asteroid, planetary and lunar exploration, alongside mining operations. Designed to withstand exposure to radiation, high accelerations experienced during space launch, and extreme temperatures, SCAR-E will be capable of in-orbit asset maintenance such as spacewalking and extravehicular activity. These unique features will also enable them to function in hostile environments here on Earth, primarily in the fields of nuclear decommissioning, critical infrastructure inspection, mine clearance, and search & rescue operations.
