Mangalyaan - The Mars mission : Some Facts

Mangalyaan
Some facts on Mars mission

Spacecraft facts:

  • Its main engine generates 440 Newtons of thrust.
  • Launch mass: 1350 kg.
  • It bears a single solar panel, 1.4 by 1.8 meters, producing 750W at Mars. [Note: This doesn't jibe with the single image that I have managed to find of the orbiter, posted below; that one appears to have a three-section panel, with each section possibly 1.4 by 1.8 meters. I can't explain the discrepancy.]
  • For attitude control it has four reaction wheels, eight 22-Newton thrusters.
  • Those are mostly pretty similar to Chandrayaan-1, except for the size of the solar panel. Chandrayaan-1 had a single 2.15-by-1.8-meter panel that generated 750W at the Moon. My guess is that the diagram below is correct and that the Mars spacecraft has a single solar array consisting of three panels 1.4 by 1.8 meters each, which would, together, manage to produce similar power at Mars that the single, larger panel did at the Moon. 
  • Five instruments have been selected, including: 
    • A color camera 
    • A Thermal Infrared Imaging System 
    • A Lyman-alpha photometer 
    • An Exospheric Neutral Composition Analyzer 
    • A Methane Sensor 
  • The engineering model is complete, and the flight model should be completed in March. 
  • ISRO expects instruments to be delivered in March for integration beginning in April. 
  • Launch to Earth orbit will take place "some time in October." 
  • The spacecraft will depart Earth orbit on November 26 and arrive at Mars on September 22, 2014.

India conducts missile interception test, direct hit at Endo Atmospheric level

India today flight tested fourth consecutive successful Interceptor Missile test against Incoming Ballistic Missile in Endo atmospheric regime at 15 Km altitude at 1005 hrs and achieved direct Hit.The Defence Research and Development Organisation (DRDO) made, single stage Interceptor Missile fitted with Directional Warhead and other advanced systems has neutralized the target which was mimicking incoming enemy Ballistic Missile.To mimic the incoming enemy’s ballistic missile trajectory, a target missile was launched from Launch Complex – III, ITR Chandipur. Interceptor Missile fitted with directional warhead was launched from Wheeler Island and destroyed Target Missile which broke into fragments and was tracked by various Radars and other sensors. All weapon system elements including Command and Control, Communication and Radars performed satisfactorily.Present among the user representatives’ were Air Marshal PK Barbora, PVSM, VM, ADC, Vice Chief of Air Staff, IAF and Maj Gen VK Saxen…

Indigenous tank T-90 Bhishma rolls out

The first batch of the indigenously built T-90 Bhishma tanks was on Monday (August 24) flagged off by Minister of State for Defence MM Pallam Raju at the rolling out ceremony held at the Heavy Vehicles Factory, Avadi, in Chennai.
The T-90S tank incorporates many new technologies in terms of mobility, protection, fighting capabilities, safety and communication.
The tank is equipped with 125mm smooth bore gun stabilised in Elevation and Azimuth, 12.7mm anti-craft machine gun and 7.62mm co-axial machine gun supported with high accuracy sighting systems and Automatic Loader ensuring high rate of fire.
A significant feature of this tank is its capability to fire guided missile in addition to conventional ammunition using the same main gun barrel. The integrated fire control system consisting of the gunner’s sight, guided weapon system and ballistic computer facilitates accurate firing of conventional ammunitions as well as the guided missiles.
The built in Explosive Reactive Ar…

GSLV Mark III with crew module launched successfully

India successfully launched its biggest ever rocket on Thursday, including an unmanned capsule which could one day send astronauts into space, the latest accomplishment of its ramped-up space programme.
The rocket, designed to carry heavier communication and other satellites into higher orbit, blasted off from Sriharikota in Andhra Pradesh.
On Twitter, Prime Minister Narendra Modi hailed the test mission as "yet another triumph of (the) brilliance and hard work of our scientists."
"This was a very significant day in the history of (the) Indian space programme," Indian Space Research Organisation (ISRO) chairman KS Radhakrishnan said from mission control as fellow scientists clapped and cheered.
ISRO scientists have been riding high since an Indian spacecraft successfully reached Mars in September on a shoe-string budget, winning Asia's race to the Red Planet and sparking an outpouring of national pride.
Although India has successfully launched lighter satellit…
