Tianwen, meaning ‘ heavenly questions’, consists of a planetary orbiter, lander and rover. Its objectives are to search for evidence of current and past life, and assess the planet’s environment 📸Sprt98 • CC BY-SA 4.0

Successful space travel often means pooling resources, and we are happy to support the new martian mission with our network of antennas as well as with our spacecraft, currently in orbit at the Red Planet

Our ground station in French Guiana, South America, caught signals from the spacecraft as it separated from the launcher after liftoff, providing information on its distance, movements and enabling communications 📶 📡

After liftoff and until Tianwen-1 enters martian orbit, ESA's New Norcia and Cebreros stations will make a total of 8 communication linkups with the spacecraft to support a highly precise navigation technique known as ‘Delta-DOR’

Once at the Red Planet, will provide data relay support, acting as a go-between (alongside the Chinese orbiter) for data gathered by the rover on the martian surface and ground stations on Earth We can't wait to see what Tianwen-1 discovers!
