Where is ExoMars Trace Gas Orbiter right now?

Orbital Radar tracks ExoMars Trace Gas Orbiter in real time from NASA JPL Horizons ephemeris data, showing its live distance from Earth and the Sun, current speed and one-way signal delay, updated every 60 seconds. Sniffing for trace gases like methane in Mars's atmosphere — key to understanding whether the planet has active geological or biological processes.

How far is ExoMars Trace Gas Orbiter from Earth?

ExoMars Trace Gas Orbiter's distance from Earth changes constantly as both bodies move through the solar system. The live figure — in kilometres and astronomical units (AU), with the matching light-travel (signal) time — is shown at the top of this page and refreshes automatically.

Sniffing for Methane

The ExoMars Trace Gas Orbiter (TGO) is a joint ESA/Roscosmos mission designed to detect and map trace gases in Mars's atmosphere with unprecedented sensitivity — particularly methane, which on Earth is primarily produced by biological processes. TGO can detect atmospheric constituents at concentrations as low as a few parts per trillion.

Mars Data Relay

Beyond its science mission, TGO serves as a critical communications relay for current and future Mars surface missions, including current and future ESA and international surface missions. Its colour stereo camera (CaSSIS) has captured some of the most striking high-resolution colour images of the Martian surface.
