DARPA’s NOM4D program aims to revolutionize space construction by developing lightweight materials for in-orbit assembly. Launched in 2022, the initiative addresses cargo capacity challenges faced in traditional space missions. Caltech will demonstrate a free-flying autonomous robotic system for constructing advanced composite structures

February marks Mars in retrograde, an illusion caused by Earth’s orbital speed. This optical phenomenon creates a perception of Mars moving backward but has no scientific basis for doom. Mars retrograde occurs every two years, offering a chance to marvel at our
