What Went Wrong with the Schiaparelli Mars landing
The Schiaparelli probe tragically failed to land on Mars due to its parachute malfunctioning, resulting in a crash at high speed. Despite this setback for the European Space Agency, the ExoMars Trace Gas Orbiter remains successful, set to study methane in the Martian atmosphere, making the overall mission worthwhile.
Schiaparelli’s landing on Mars
The Schiaparelli Spacecraft tragically failed to land on Mars, crashing at 300 km/h. Launched on March 14, 2016, with the ExoMars Trace Gas Orbiter, it aimed to study Martian surface conditions. It only planned to be operational for a week because it lacked solar panels, relying solely on a non-rechargeable battery.
ExoMars TGO: Tracking Methane in the Martian Atmosphere
The ExoMars Trace Gas Orbiter, launched in 2016, aimed to study methane on Mars, a gas that might indicate geological or biological activity. Initially suspected to exist in trace amounts, recent findings revealed no detectable methane, leading to questions about previous measurements and highlighting mysteries around Mars' atmospheric composition.
