The Royal Astronomical Society (RAS) is alarmed by the threat to ground-based astronomy posed by proposals put forward by Elon Musk’s SpaceX and Reflect Orbital. SpaceX has applied to launch one million satellites to act […]

Heat shields are designed to protect the surface and cargo of a spacecraft as it enters an atmosphere. Aerospace engineers in The Grainger College of Engineering at the University of Illinois Urbana-Champaign recently observed a […]

Dragonfly integration and testing—the activities involved in assembling the mission’s rotorcraft lander and testing it for the rigors of launch and extreme conditions of space—is officially underway in clean rooms and control rooms at the […]

Cosmic rays are one of the greatest challenges for space travel and pose a considerable risk to humans and materials. For the first time on European soil, an international research team in collaboration with the […]
