Mars 96

          Mars 8 otherwise called Mars 96 which was launched by the Russian Space Forces to Mars in 1996. This spacecraft was programmed based on the Phobos Probes of Mars 1988. It was very ambitious mission at that time. This mission included an orbiter, Surface Stations and Surface penetrators. Mars 96 had many scientific instruments provided by the European countries.

AIM:  The prime aim of this mission was to understand the evolutionary history of formation of Martian surface, atmosphere and interior structure of planet mars.

ORBITER DESIGN: Mars 96 was similar to the model and design of Phobos orbiters. Its body had high gain antenna and low gain antenna for communications. Two solar panel at the side is set for the power source. It also had two surface stations and two penetrators for fuel propulsion system. The total mass of Mars 96 spacecraft was 6,180 kg.

 TRAVEL AND LANDING:

     It was planned that, after 10 months of space travel towards mars, it will successfully reach Mars on 12th September 1997( Approx). Before five days they will release the two surface penetrators and staions to land. But the mission resulted in Failure.

CONCLUSION: 

     Mars 96 was unsuccessful because of the malfunction of Proton K/D upper stage ignition. It re-entered into the earth's atmosphere and the spacecraft debris fell into the Pacific Ocean. Sometimes it was believed that its plutonium fuel was responsible for the spacecraft failure itself. Mars 96 was a huge spacecrafts which carried nearly 44-45 scientific instruments. Later on, all the missions to mars was constructed based on the scientific plan of Mars 96. For Example: Mars Express

Prop-M Rover

DESCRIPTION:

          Soviet Russia sent Prop-M Rover along with Mars 3 lander weighting 4.5 Kilograms. The rover was planned to move across the surface of Mars. Small metal rods in the side was used for autonomous obstacle avoidance, because it is difficult to control the rover from earth using radio signals. It take too long to travel from earth to mars as well as mars to earth.

DESIGN:

          The Prop-M Rover designed like a square box and the movement was provided by two skis. In front Obstacle detection bars were mounted. The square box had a protrusion at the center.

INSTRUMENTS CARRIED:

       1) Penetrometer

       2) Densitometer

OBJECTIVES:

          The rover was planned to move on the surface of mars with the help of Television Camera. And to detect some organic materials with help of penetrators.

ENTRY:

          Prop-M rover was released on 2nd December 1971. It entered the martian atmosphere at a speed of 5.7 Km/s and successfully landed.

CONTACT:

          After 14.5 seconds of landing on the Martian surface, no signals were received from the rover. Communications lost from rover. It may be caused by the powerful dust storms causing damage to the communication system. The mission resulted in Partial Failure.

Mars Reconnaissance Orbiter Completes 50000th Orbit around Mars.

                                    Mars Reconnaissance Orbiter is an american spacecraft designed to conduct multiple experiment for the exploration of Mars. It was designed under the supervision of NASA Project director Lookheed Martin ( Jet Propulsion Laboratory) and it was controlled by California Institute of Technology,USA. It was launched on 12 August 2005 from Cape Canaveral Air force station and reached mars orbit on 10 March 2010. It became one of the five active mission on Mars (2001 Mars odyssey, Mars Global Surveyor, Mars Express, Mars Exploration Rovers ( Twin Rovers = Spirit and Opportunity). It became the best relay satellite for the measurement of weather monitoring, choose site for future landing missions and an intermediate to communicate between the Mars Exploration Rovers and Earth. It carried many scientific instruments such as radars, spectrometers to study mars. It is listed as one of the currently active mission on Mars. It completed its 50,000th orbit around Mars on 27 March 2017.
