    About Red Planet Day

    • It is observed annually to mark the launch of the Mariner 4 spacecraft on the Planet Mars on November 28, 1964. 
    • This was the first time that a spacecraft undertook the first flyby of the red planet, becoming the first-ever spacecraft to take close-up photographs of another planet.

    Other Missions  Related to Mars 

    • Viking missions of the 1970s and the 1980s:  The Viking missions in the mid-seventies carried out the first chemical analysis of Martian soil, as well as four biology experiments to detect biological activity.
    • Odyssey, 2001 and water on Mars: In 2001, the Gamma Ray Spectrometer on board the Mars Odyssey spacecraft detected a fascinating hydrogen signature that seemed to indicate the presence of water ice. 
    • NASA’s Phoenix landed on the Martian North Pole in May 2008 and survived for about 150 days.
      •  The robotic arms of Phoenix scooped soil and ice from the surface, heated the material in eight ovens, and measured the composition of the gases with a mass spectrometer. 
    • NASA has a lander (Mars Insight), a rover (Curiosity), and three orbiters (Mars Reconnaissance Orbiter, Mars Odyssey, MAVEN); India has an orbiter (Mangalyaan-1); the EU has 2 orbiters (Mars Express and ExoMars Trace Gas Orbiter), and China and UAE will have an orbiter each (Hope and Tianwen-1 respectively).
    • The UAE mission will study the Martian atmosphere and will seek to address the billion-dollar question of how and why Mars lost its atmosphere. 
    • India’s Mars Orbiter Mission — a technology demonstration venture — carried five scientific payloads (Total 15 kg) collecting data on surface geology, morphology, atmospheric processes, surface temperature, and atmospheric escape process.
