NASA's Mars 2020
Name	NASA's Mars 2020
Operator	National Aeronautics and Space Administration

NASA's Mars 2020 is a robotic spacecraft mission that was launched by the National Aeronautics and Space Administration to explore Mars and search for signs of past or present life on Mars. The mission is part of the Mars Exploration Program and involves collaboration with European Space Agency, Canadian Space Agency, and other international partners like Russia's Roscosmos and Japan's JAXA. The mission builds upon the discoveries of previous Mars rover missions, including Curiosity rover and Perseverance rover, and is designed to pave the way for future human mission to Mars.

Overview

The Mars 2020 mission is a significant step in the exploration of Mars and the search for life beyond Earth. The mission involves a rover called Perseverance rover, which is equipped with a range of scientific instruments, including Alpha Particle X-Ray Spectrometer and Radar Imager for Mars' Subsurface Exploration. The rover is designed to explore Jezero crater, a former lake bed that is believed to have been home to a lake on Mars around 3.5 billion years ago. The mission is also supported by the Mars Helicopter Ingenuity, a small helicopter that is designed to test the feasibility of rotary-wing aircraft on Mars. The mission has involved collaboration with a range of international partners, including University of California, Berkeley, California Institute of Technology, and Jet Propulsion Laboratory.

Spacecraft Design

The Perseverance rover is a robotic spacecraft that is designed to explore the surface of Mars. The rover is equipped with a range of scientific instruments, including Planetary Instrument for X-Ray Lithochemistry and Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals. The rover is powered by a radioisotope thermoelectric generator and has a mass of around 1,043 kg. The rover is designed to communicate with Earth via the Deep Space Network, which is operated by the National Aeronautics and Space Administration. The rover's design is based on the Curiosity rover, which has been exploring Gale crater since 2012. The mission has also involved the development of new technologies, including Multi-Mission Radioisotope Thermoelectric Generator and Descent Stage.

Mission Objectives

The primary objective of the Mars 2020 mission is to explore Jezero crater and search for signs of past or present life on Mars. The mission also aims to study the geology of Mars and understand the climate of Mars. The mission involves a range of scientific experiments, including the study of Martian geology and the search for biosignatures. The mission is also designed to test the feasibility of sample return from Mars and to pave the way for future human mission to Mars. The mission has involved collaboration with a range of international partners, including European Space Agency, Canadian Space Agency, and Russia's Roscosmos. The mission has also involved the development of new technologies, including Sample Collection System and Planetary Instrument for X-Ray Lithochemistry.

Launch and Transit

The Mars 2020 mission was launched on July 30, 2020, from Cape Canaveral Air Force Station using an Atlas V rocket. The launch was carried out by United Launch Alliance and involved a range of international partners, including European Space Agency and Canadian Space Agency. The transit to Mars took around 6.5 months, during which time the Perseverance rover was in a state of hibernation. The rover was equipped with a range of instruments, including Star Tracker and Inertial Measurement Unit, to navigate the journey to Mars. The mission has involved collaboration with a range of international partners, including Jet Propulsion Laboratory and University of California, Berkeley.

Landing and Surface Operations

The Perseverance rover landed on Mars on February 18, 2021, in Jezero crater. The landing was carried out using a sky crane system, which is similar to the system used by the Curiosity rover. The rover is equipped with a range of instruments, including Radar Imager for Mars' Subsurface Exploration and Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals, to study the surface of Mars. The rover is designed to operate for at least 687 days, during which time it will explore Jezero crater and search for signs of past or present life on Mars. The mission has involved collaboration with a range of international partners, including European Space Agency and Canadian Space Agency.

Results and Findings

The Mars 2020 mission has already made a number of significant discoveries, including the detection of methane on Mars and the discovery of ancient lake beds in Jezero crater. The mission has also provided valuable insights into the geology of Mars and the climate of Mars. The mission has involved collaboration with a range of international partners, including University of California, Berkeley, California Institute of Technology, and Jet Propulsion Laboratory. The mission has also involved the development of new technologies, including Sample Collection System and Planetary Instrument for X-Ray Lithochemistry. The results of the mission will be used to inform future Mars exploration missions, including the European Space Agency's ExoMars mission and the National Aeronautics and Space Administration's Mars Sample Return mission. The mission has also involved collaboration with a range of international partners, including Russia's Roscosmos and Japan's JAXA.
