Tomcat drew a circle on a piece of paper. "This is Mars with a radius of 3,389 kilometers. It's about half of Earth's radius. The equatorial length is 21,330 kilometers, which is also about half of Earth's."
Tang Yue nodded.
Tomcat then drew a tiny dot on the circle. "This here is where Kunlun Station and the Eagle are. It's on the northern hemisphere on Mars and located in an impact basin known as the Isidis Planitia. The exact location is 12.54°N and 87.0°E. We are near the equator and northeast from us is the Utopia Planitia.
"The Eagle will launch from this location." Tomcat pointed at the piece of paper with a pen tip.
