Chinese researchers have successfully collected lunar samples from dark areas using robotic arms and drills thanks to a meticulous simulation process. The Chang’e 6 mission, which aims to retrieve lunar samples, has reached the halfway mark with the spacecraft carrying the samples entering orbit on June 4.
The process of collecting lunar samples involves coordinating science and engineering efforts. Researchers first simulate the probe’s operating area 380,000 km from Earth. Using data from relay satellites, they create a realistic model of the region that guides decision-making for the mission. By analyzing photographic data and building digital models, researchers create a 1:1 scale simulation of the lunar surface environment.
In this simulated environment, researchers select sample collection locations and establish rock sample collection methods. They place a sample collection device to replicate the real device on the Moon and determine how the robot arm will operate at each location using a smart sampling system. The probe successfully collects lunar samples through a three-hour drilling operation at more than 10 selected locations in the dark area.
Overall, Chinese researchers have successfully collected lunar samples in dark areas using robotic arms and drills through careful planning and execution of a meticulous simulation process that involved analyzing data from relay satellites, building digital models, and creating a realistic environment for sample collection.
