Collecting material from an asteroid seems like a simple task. In reality, it isn’t. Low gravity, high rotational speeds, lack of air, and other constraints make collecting material from any asteroid difficult. But that won’t stop engineers from trying. A team from Beijing Spacecrafts and the Guangdong University of Technology recently published a paper that described a novel system for doing so – using an ultrasonic drill and gas “conveyor belt.
Another mission, Rosetta, attempted a more involved sample collection process that involved anchoring to the asteroid itself. However, its lander, Philae, didn’t successfully attach to the asteroid and never managed to return samples to the Rosetta orbiter. Its collection mechanism known as the Sampling and Drilling Device was the most similar to conventional sample collection here on Earth, and utilized a drill.That concept of drilling is at the heart of the new proposed system.
