Where is the ExoMars TGO Spacecraft right now?

The app above shows the trajectory of the ExoMars TGO Spacecraft and where it is right now. You can also wind the animation backwards in time to watch its launch and journey to Mars.

ExoMars 2016 Mission

This is the first of 2 ExoMars missions, the second of which will occur in 2020.

It consists of an orbiter (called the "Trace Gas Orbiter") and a lander (called "Schiaparelli") which travelled together and then separate as they reach Mars. The main objectives of this mission are to search for evidence of methane and other trace atmospheric gases that could be signatures of active biological or geological processes and to test key technologies in preparation for ESA's contribution to subsequent missions to Mars.

The mission was launched on 14 March 2016 on a Proton rocket which, due to advantageous Earth Mars positioning, flew direct to Mars in 7 months. It arrived at Mars 19th of October.

Three days before reaching the atmosphere of Mars, Schiaparelli was ejected from the Orbiter towards the Red Planet. Schiaparelli then coasted towards its destination, entered the Martian atmosphere at 21,000 km/h, decelerated using aero-braking and a parachute. It was then meant to brake with the aid of a thruster system before landing on the surface of the planet. Unfortunately something went wrong in the final stages and the thruster system switched off far to early. The lander then fell from somewhere between 2 and 4 km to strike the surface at a very high speed and possibly exploded (due to still being full of fuel) on the surface. Although this is a setback to the overall ExoMars mission, the lander was meant as a test of ESA's landing technology so as long as lessons can be learnt, it is not a complete failure.

The ExoMars Orbiter was successfully inserted into an elliptical orbit around Mars and will be manoeuvred into a circular, approximately 400km altitude orbit ready to conduct its scientific mission.

Trace Gas Orbiter

The Orbiter will perform detailed, remote observations of the Martian atmosphere, searching for evidence of gases of possible biological importance, such as methane and its degradation products. The instruments on the Orbiter will carry out a variety of measurements to investigate the location and nature of sources that produce these gases. The scientific mission is expected to begin in December 2017 and will run for five years. The Trace Gas Orbiter will also be used to relay data for the 2020 rover mission of the ExoMars programme until the end of 2022.

Schiaparelli Lander

Schiaparelli - an entry, descent and landing demonstrator module - was designed to prove ESA's technology for landing on the surface of Mars with a controlled landing orientation and touchdown velocity. The design of Schiaparelli maximises the use of technologies already in development within the ExoMars programme. These technologies include: special material for thermal protection, a parachute system, a radar Doppler altimeter system, and a final braking system controlled by liquid propulsion.

Schiaparelli was expected to survive on the surface of Mars for a short time by using the excess energy capacity of its batteries. The science possibilities of Schiaparelli were limited by the absence of long term power and the fixed amount of space and resources that can be accommodated within the module; however, a set of scientific sensors were included to perform limited, but useful, surface science.
