, A Mars orbiter, part of ExoMars programme, Missions are ordered by launch date.  With NASA's funding for this project cancelled, most of ExoMars' plans had to be restructured. That's why it's packing PIXL. Then the TGO gradually underwent aerobraking for seven months into a more circular orbit for science observations and will provide communications relay for the Rosalind Franklin rover to be launched in 2020, and will continue serving as a relay satellite for future landed missions.. The cost of the ExoMars mission to the European Space Agency, including the Trace Gas Orbiter and Schiaparelli lander plus the 2020 ExoMars Rover, is expected to be about 1.3 billion euros ($1.4 billion). When accelerating the wheel, the satellite body to which the wheels are directly attached will rotate to the opposite direction as a result of the introduced counter torque. After deployment, the Orbiter monitored the UHF transmission from Schiaparelli from its coasting to Mars until its landing on the Red Planet. It also provides a base for the attachment of the Schiaparelli lander on the zenith side of the spacecraft.
The second part of the mission, now due to launch in 2022, is sending a high-tech rover to land on Mars.
TGO makes use of a pair of rechargeable Lithium-Ion batteries to deliver electrical power when passing through eclipse or during periods of increased power demand. The Trace Gas Orbiter carries a scientific payload capable of addressing this scientific question, namely the detection and characterisation of trace gases in the Martian atmosphere. The instruments on the orbiter are carrying out a variety of measurements to investigate the location and nature of sources that produce these gases.
 However, if methane is found in the presence of gases such as sulfur dioxide (SO2), that would be an indication that the methane is a byproduct of geological processes. The Attitude Determination and Control System of the Trace Gas Orbiter consists of a pair of star trackers, two Coarse Sun Sensors and two inertial measurement units for attitude determination and four Reaction Wheels plus the Reaction Control Thrusters for attitude actuation. Made of a pair of two-wheeled vehicles, DuAxel is designed to descend craters and near-vertical cliffs on the Moon, Mars, and beyond. Detection sensitivities are at levels of 100 parts per trillion, improved to 10 parts per trillion or better by averaging spectra which could be taken at several spectra per second. ExoMars is a collaborative effort between the European Space Agency (ESA) and Russia’s Roscosmos. The wheels are 35 centimeters in diameter and measure 12cm in height with a mass of around 5 Kilograms. The Trace Gas Orbiter (TGO) spacecraft was designed by ESA, while Roscosmos provided the launch vehicle, a Proton rocket. During November 2016 and March 2017, there were two opportunities to perform some science measurements, primarily for the purposes of calibrating the science instruments. Now that the heat probe is below the Martian surface, InSight's arm will scoop more soil on top to help it keep digging. The oscillators provide a stable frequency reference to the EUT and the Small Deep Space Transponder as well as a one-way Doppler ranging capability. Covered with triple-junction Gallium-Arsenide solar cells, each array is comprised of two panels, being 3.12 meters long and 1.74 meters wide, bringing the length of each array to 7.9 meters.
Schiaparelli separating from the Trace Gas Orbiter. March 2018: Communications Relay Operations, March 2018 - December 2019: Primary Science Operations. Originally, the ExoMars concept consisted of a large robotic rover being part of ESA's Aurora Programmeas a Flagship mission and was approved by the European Space Agency ministers in December 2005. its angle of travel with respect to the equator to almost 74° from the 7° of its October arrival. On 19 October, the Trace Gas Orbiter was inserted into an elliptical orbit around Mars. It was planned to then brake with the aid of a thruster system before landing on the surface of the planet, but an anomaly in the measurement and navigation system meant that the parachute and the backshell were prematurely released, followed by a brief firing of the braking thrusters and finally activation of the on-ground systems as if Schiaparelli had already landed.  NASA provided an Electra telecommunications relay and navigation instrument to assure communications between probes and rovers on the surface of Mars and controllers on Earth. By working together, the ExoMars mission has already put a spacecraft in orbit around Mars – the Trace Gas Orbiter. Site Manager: Electra has been used on a number of previous Mars missions and has become the standard system used to relay data from Mars rovers. Weather sensors aboard the InSight lander stopped providing data on Aug. 16, 2020, a result of an issue affecting the sensor suite's electronics. The Electra terminal consists of dual string UHF Transceivers, dual string Ultrastable Oscillators for precision navigation and surface positioning and a low gain UHF antenna pointing nadir. Kristen Erickson MEDLI2 is a collection of sensors that take measurements during the atmospheric entry phase of the Mars 2020 mission. NOMR – Nominal Mode using Reaction Wheels: This control mode delivers fine 3-axis pointing mode based on Gyro-Stellar attitude frames with use of the reaction wheels for routine pointing. The propellant tanks are facilitated within the central tube to allow the center of gravity of the vehicle to remain in one place when the tanks are emptied.
