Mars 96

Mars 96 was a Roscosmos mission intended to study Mars, Phobos, and the Martian atmosphere. The mission was designed to investigate the geology of Mars, climate of Mars, and the atmosphere of Mars, with a focus on the polar ice caps and the valley networks carved by water on Mars. The spacecraft was equipped with a range of instruments, including a gamma-ray spectrometer and a radar altimeter, developed in collaboration with NASA, ESA, and CNES. The mission was also supported by Russian Academy of Sciences, Max Planck Society, and University of California, Berkeley.

Introduction

The Mars 96 mission was part of a series of Soviet and Russian missions to Mars, including Phobos 1 and Phobos 2, which were launched in the late 1980s. The mission was designed to build on the successes of these earlier missions, with a focus on the geology of Mars and the climate of Mars. The spacecraft was developed by NPO Lavochkin, a leading Russian space manufacturer, in collaboration with JPL, ESA, and CNES. The mission was also supported by University of Oxford, Caltech, and MIT.

Spacecraft Design

The Mars 96 spacecraft was designed to be a orbiter, with a mass of approximately 3,069 kilograms (6,767 pounds). The spacecraft was equipped with a range of instruments, including a gamma-ray spectrometer developed by LANL and University of Arizona, a radar altimeter developed by JPL and UCLA, and a magnetometer developed by University of Michigan and University of Colorado Boulder. The spacecraft was powered by a combination of solar panels and RTGs, developed by Boeing and General Electric. The spacecraft was also equipped with a high-gain antenna developed by Northrop Grumman and Harris Corporation.

Mission Objectives

The primary objectives of the Mars 96 mission were to study the geology of Mars, climate of Mars, and the atmosphere of Mars. The mission was designed to investigate the polar ice caps and the valley networks carved by water on Mars, with a focus on the geological history of the planet. The spacecraft was also equipped with instruments to study the magnetosphere of Mars and the solar wind interactions with the Martian atmosphere. The mission was supported by NASA's Mars Exploration Program, ESA's ExoMars program, and Roscosmos' Phobos-Grunt mission.

Launch and Failure

The Mars 96 spacecraft was launched on November 16, 1996, from the Baikonur Cosmodrome in Kazakhstan using a Proton-K launch vehicle developed by Khrunichev State Research and Production Space Center. However, the launch vehicle failed to reach orbit, and the spacecraft crashed into the Pacific Ocean near Chile. The failure was attributed to a malfunction in the Block D-2 upper stage, developed by RKK Energia and TsNIIMash. The failure of the Mars 96 mission was a significant setback for the Russian space program, but it did not deter future missions to Mars, including the Phobos-Grunt mission and the ExoMars program.

Aftermath and Legacy

The failure of the Mars 96 mission was a significant disappointment for the Russian space program and the international scientific community. However, the mission did provide valuable lessons for future missions to Mars, including the importance of rigorous testing and validation of launch vehicles and spacecraft systems. The mission also highlighted the challenges of interplanetary space travel and the need for international cooperation and collaboration in space exploration. The legacy of the Mars 96 mission can be seen in the success of subsequent missions to Mars, including the Curiosity Rover and the ESA's Schiaparelli EDM lander, developed in collaboration with Thales Alenia Space and Airbus Defence and Space. The mission also paved the way for future collaborations between Roscosmos, NASA, ESA, and other space agencies, including the ExoMars program and the Mars 2020 mission.
