Mars 2022 Orbiter

Mars 2022 Orbiter. The Mars 2022 Orbiter is a collaborative mission between the European Space Agency and Roscosmos, with contributions from NASA, Canadian Space Agency, and Indian Space Research Organisation. This mission aims to explore the Mars atmosphere, surface, and subsurface, building upon the discoveries of previous missions such as Mars Express, Mars Reconnaissance Orbiter, and Mars Odyssey. The Mars 2022 Orbiter will work in tandem with other ongoing and future missions, including the Perseverance rover, Curiosity rover, and ExoMars rover, to provide a comprehensive understanding of the Red Planet.

Introduction

The Mars 2022 Orbiter is part of a broader effort to explore Mars and understand its potential for supporting life, as well as its geological and climatic history. This mission draws upon the expertise and experience of various space agencies, including the European Space Agency, Roscosmos, NASA, Canadian Space Agency, and Indian Space Research Organisation. By leveraging the capabilities of these agencies, the Mars 2022 Orbiter will contribute significantly to our knowledge of Mars, complementing the findings of earlier missions such as Viking 1, Viking 2, Mars Pathfinder, and Mars Science Laboratory. The mission will also pave the way for future human exploration of Mars, as envisioned by programs such as Artemis and SpaceX Starship.

Spacecraft Design

The Mars 2022 Orbiter spacecraft is designed to withstand the harsh conditions of Mars' environment, including extreme temperatures and radiation. The spacecraft's design is based on the ExoMars Trace Gas Orbiter, with modifications to accommodate the specific objectives of the Mars 2022 Orbiter mission. The spacecraft will be equipped with a high-gain antenna for communication with Earth, as well as solar panels to generate power. The Mars 2022 Orbiter will also utilize advanced propulsion systems, such as ion engines and hall effect thrusters, to maintain its orbit and perform maneuvers. The spacecraft's design and development involve collaboration between Thales Alenia Space, Airbus Defence and Space, and Lavochkin, among other companies.

Mission Objectives

The primary objectives of the Mars 2022 Orbiter mission are to study the Mars atmosphere, surface, and subsurface, with a focus on understanding the planet's geological and climatic history. The mission will investigate the presence of water and methane on Mars, as well as the planet's potential for supporting life. The Mars 2022 Orbiter will also examine the Mars magnetosphere, ionosphere, and upper atmosphere, providing insights into the planet's interaction with the solar wind and cosmic rays. Additionally, the mission will search for signs of tectonic activity and volcanism on Mars, which could indicate the presence of geothermal energy and hydrothermal activity. The mission's objectives are aligned with those of other ongoing and future missions, including the Europa Clipper and Enceladus Life Finder.

Launch and Orbit

The Mars 2022 Orbiter is scheduled to launch on a Proton rocket from the Baikonur Cosmodrome, with an Ariane 5 or Ariane 6 rocket serving as a backup option. The spacecraft will follow a Hohmann transfer orbit to reach Mars, with a journey time of approximately 6-7 months. Upon arrival, the Mars 2022 Orbiter will enter into a polar orbit around Mars, with an altitude of around 200-400 kilometers. The spacecraft's orbit will be adjusted periodically to maintain optimal communication with Earth and to ensure the best possible observation conditions. The Mars 2022 Orbiter will operate in conjunction with other Mars orbiters, including the Mars Reconnaissance Orbiter and Mars Odyssey, to provide a comprehensive understanding of the Red Planet.

Scientific Instruments

The Mars 2022 Orbiter will be equipped with a suite of advanced scientific instruments, including a radar system, spectrometers, and cameras. The radar system, developed by Thales Alenia Space and NASA Jet Propulsion Laboratory, will study the Mars subsurface and search for signs of water and ice. The spectrometers, provided by European Space Agency and Roscosmos, will analyze the Mars atmosphere and surface, searching for signs of methane and other biomarkers. The cameras, developed by Max Planck Institute for Solar System Research and University of Arizona, will capture high-resolution images of the Mars surface, providing insights into the planet's geological and climatic history. The Mars 2022 Orbiter will also carry instruments developed by Canadian Space Agency and Indian Space Research Organisation, such as a laser altimeter and a magnetometer.

Mission Timeline

The Mars 2022 Orbiter mission is scheduled to last for at least 2 years, with the possibility of extension depending on the spacecraft's performance and the achievement of its objectives. The mission will begin with a 6-7 month journey to Mars, followed by a series of orbit adjustments and instrument calibrations. The Mars 2022 Orbiter will then enter into a routine observation phase, with periodic adjustments to its orbit and instrument settings. The mission will involve collaboration with other Mars missions, including the Perseverance rover and ExoMars rover, to provide a comprehensive understanding of the Red Planet. The Mars 2022 Orbiter will also contribute to the development of future Mars missions, such as the Sample Return and Human Exploration initiatives, by providing critical data and insights into the Mars environment.
