Going further into space – the exploration of Mars through the eyes of machines
On 22nd of January 2026 we crossed the boundary between the Earth and the cosmos thanks to the lecture given by Paweł Czerniec, a specialist of mapping the Martian terrain. Our guest explained to us the way he’s using photogrammetry and Python in order to create a 3D map of the red planet. Photogrammetry is another field of science that uses photos. It involves creating maps or models in 3D, out of photo documentation of an area or object. One of the ways to do so is by an algorithm called “structure from motion”. Which uses the focal length of lens. Photogrammetry isn’t a tool made just for archeologists who explore the lost parts of our history on Earth, but also for those who want to go beyond our atmosphere and discover the mysteries of Mars. We can say that the field of science is just a perfect fit for explorers.
To create the three-dimensional map of Mars, Paweł Czernic used the data collected by NASA as a part of the “MARS 2020” mission. Currently, it can be found on the internet for free. The photo documentation came from a drone called Ingenuity (aka ,,Ginny”) and a rover Perseverance. The data our guest was working with came mostly from the first one mentioned. The drone was equipped with two cameras – one with a purpose of taking photos in color and the other one to receive data in black and white, richer in information needed for a deeper analysis. Photos taken by Ginny were sent from Mars to Earth through radio waves. Ingenuity worked flawlessly for 4 years before an unfortunate crash during the 72nd flight. At the very least, the drone collected enough data to create a map of the areas over which it flew. That impressive outcome was achievable thanks to the Agisoft software and the dedication of Paweł Czernic.
Besides the lecture, the guest shared his memories connected to his science path, which has developed on the Polytechnic of Warsaw. For example, we got to know his experience with classes conducted in English. Also, we had our questions regarding the topic answered – the vast majority was about the MARS 2020 mission, the built and functioning of Ginny etc. The meeting was another exciting experience with the indefinite world of science. It’s thanks to such lectures that the members of LEOO have the opportunity to explore more and more possibilities related to remote sensing and the photo analysis.
