CubeSats are becoming ever more popular, with around 2,400 total launched so far. However, the small size limits their options for fundamental space exploration technologies, including propulsion. They become even more critical when mission planners design missions that require them to travel to other planets or even asteroids. A team from Khalifa University of Science and Technology in Abu Dhabi recently released a review of the different Cubesat propulsion technologies currently available – let’s look at their advantages and disadvantages.

Swarms of Orbiting Sensors Could Map An Asteroid’s Surface
It seems like every month, a new story appears announcing the discovery of thousands of new asteroids. Tracking these small body objects from ground and even space-based telescopes helps follow their overall trajectory. But understanding what they’re made of is much more difficult using such “remote sensing” techniques. To do so, plenty of projects get more up close and personal with the asteroid itself, including one from Dr. Sigrid Elschot and her colleagues from Stanford, which was supported by NASA’s Institute for Advanced Concepts back in 2018. It uses an advanced suite of plasma sensors to detect an asteroid’s surface composition by utilizing a unique phenomenon – meteoroid impacts.
