Miniaturized jumping robots could study an asteroid's gravity

Missions focusing on small bodies in the solar system have been coming thick and fast lately. OSIRIS-Rex, Psyche, and Rosetta are all examples of projects that planned or did rendezvous with a small body in the solar system. ...

Using smart materials to deploy a Dark Age explorer

One of the most significant constraints on the size of objects placed into orbit is the size of the fairing used to put them there. Large telescopes must be stuffed into a relatively small fairing housing and deployed to ...

Protecting power grids from space weather

Activity from the sun, such as solar flares, can cause fluctuations in Earth's geomagnetic field that send electrical currents flowing through power grids. These geomagnetically induced currents (GICs) can cause problems ...
