A new mapping technique could help in the exploration of the Moon, Mars and beyond – BollyInside

Researchers have discovered a way to combine available imagery and terrain data to create high-resolution maps of the surface of planets like the Moon.

Laser altimeters, which measure changes in altitude, operate at a much lower resolution than cameras, making it difficult to map the complex and varied surface of a world like the Moon with detailed resolution. Photographs convey surface features, but it is difficult to translate the image to specific heights.

However, new methods combine terrain data with the level of sunlight shading present in optical imagery to more accurately assess terrain and structures. This development could benefit both astronauts and robotics researchers in the future. The new method was developed by Iris Fernandes, now a former Ph.D. Student at the Niels Bohr Institute, University of Copenhagen, Denmark.

Different missions provide very different data resolutions, so combining different data sources with different resolutions presents a major mathematical problem. What Fernandez and her then-advisor, the geophysicist Klaus Mosegoth, did differently was to focus on the mathematics of the problem and narrow it down to see if equations could solve the problem. was.

According to the researchers, the new approach requires far less computational power and is much faster than previous methods.

In her statement, Fernandez said she had found “a mathematical key to a door that had been locked for many years.”

Researchers have demonstrated this technology on the moon. By combining high-resolution imagery from NASA’s Lunar Reconnaissance Orbiter LROC camera with low-resolution data from the spacecraft’s Lunar Orbiter Laser Altimeter (LOLA), the authors of the paper brought the terrain resolution down to about 200 feet (60 meters). I explained that I raised it. Increased has. Up to 0.9 m (2.95 ft) per pixel.

In the future, the method could be applied to extract precise topographic details from rock formations on planetary bodies such as the Moon, Mars, asteroids, and other worlds for which topographic data are available, the authors argue. I’m here.

This method can support a variety of purposes, such as determining the safety of astronauts and rovers, or finding places of geological interest, and can be applied to images acquired from satellites, rovers, or other spacecraft. Applicable.
