After scripting history in space, India's Mars Orbiter Mission has now captured a 3D image of Mars.

In the common design, radiation is directed through an entrance slit (available light energy depends on light intensity of the source as well as the dimensions of the slit and acceptance angle of the system). The solar array provides 840 Watts of electrical power at Mars that is fed to a power distribution unit that provides power to the various systems and payloads and controls the state of charge of a 36-Amp-hour battery for night passes. Then sourcing all the components, testing and integrating them, aligning them precisely, right down to the last micron.”, Minal Sampat, the project manager, systems integration, MOM, outlined her contributions in Minnie Vaid’s book, “Working in a soundproof, pressurized “clean room” without sunshine or any other external noise for days on end—often without a break during testing— was a challenge, but the payloads [scientific instruments onboard the spacecraft, see n. 20] are like my babies.

The success of the Mangalyaan also saw India take the place of the first Asian nation to reach the Martian orbit and also the first nation in the world to do so in its maiden attempt. “When we formulated a young team for MOM, the time given to us was just eighteen months. The instrument features a Fabry-Perot Etalon sensor that uses multiple beam interferometry at wavelengths of 1,642 to 1,658 nanometers to detect the signature of Methane that has a characteristic overtone band at these wavelengths. MCC covers a spectral range of 400 to 700 nanometers – the visible spectrum. Tapan Misra, Director, SAC, said, “Women are the backbone of the organisation – they do the work yet remain invisible.”.

The engine operates and an mixture ratio (O/F) of 1.65 and has a nozzle ratio of 160 providing a specific impulse of 3,041N*sec/kg. TIS uses a 120 by 160 element bolometer array detector. Fully integrated and fueled for flight, Mangalyaan weighs in at 1,337 Kilograms. Upper stage thrust is 1,500 Kilograms. The third stage provides a total thrust of 24,900 Kilograms. The slit is placed at the effective focus of a collimator that directs collimated radiation (focused at infinity) to a diffraction grating that acts as dispersive element.

The development of the mission was initiated one year earlier. This is because all conditions that the Mars Orbiter Mission could face in outer space needed to be simulated on earth and tested well before the launch. This and other physical processes caused around 85 to 95% of the Martian Atmosphere to escape into deep space. MOM departs Earth orbit on November 30, 2013 .

PSLV launches from the Satish Dhawan Space Center located on India’s East Coast. The MSM Payload weighs 3.6 Kilograms and is designed to measure methane concentrations in the Martian atmosphere with parts per billion accuracy.

The original atmosphere would have been warmer and it would have provided a substantially higher surface pressure which would have created an environment suitable for sustaining liquid water – a requirement for life as we know it.

This coast phase allows the vehicle to fly uphill so that the fourth stage burn can increase the apogee altitude and also put a few Kilometers onto the perigee to place the stack in a stable orbit. The short film Snapshots from Afar and the book Those Magnificent Women And Their Flying Machines: ISRO’s Mission on Mars by Minnie Vaid gave an insight into the lives of these women and their story comes across as not only motivating but also changes the perspective of men dominating the profession. The core objective of MENCA is to study the exospheric neutral density and composition at altitudes as low as 372 Kilometers above the Martian surface.

Before ALTBalaji’s Mission Over Mars, meet the real women behind Mars Orbiter Mission Before we get to know more about the women scientists behind Mars Orbiter Mission through the lens of M.O.M director Vinay Waikul, here is a look at the real-life heroes of Mangalyaan. I could not leave them.”. Mangalyaan is equipped with a 2.2-meter diameter High Gain Antenna which is a parabolic X-Band reflector antenna that is used for data downlink and command uplink. The instruments started integration with the spacecraft in April to begin testing in August and September without much margin of error for meeting the launch window that stretches from October 28, 2013 to November 19, 2013. Tank pressurization is accomplished with high-pressure Helium. The debate about methane on Mars started way back in 1969 when scientists working with the Mariner 7 Spacecraft announced that the spacecraft had likely detected Methane with its Infrared Spectrometer Instrument. India became the first Asian country to reach Mars and the first in the world to successfully place a spacecraft into the Martian orbit in its very first attempt.

The mission was put together on rather short notice – being approved in August 2012 with just 15 months to go until the Interplanetary Launch window that comes once every 26 months. In 2004, data from ESA’s Mars Express Orbiter and ground-based telescope observations suggested even higher quantities of methane of up to 10ppb. The Mars Orbiter Mission (MOM), also called Mangalyaan ("Mars-craft", from Sanskrit: मंगल mangala, "Mars" and यान yāna, "craft, vehicle"), is a space probe orbiting Mars since 24 September 2014. Each 22N thruster assembly weighs 0.8 Kilograms. Following the completion of a 56.5-hour countdown, PSLV will launch with the Mangalyaan spacecraft hidden under its 3.2 by 8.3-meter payload fairing. The Main Propulsion System is centered around the Liquid Apogee Motor which has become the Indian workhorse on Geostationary Satellites and its previous Moon probe.

During the second stage burn, the launch vehicle departs the dense atmosphere – allowing the vehicle to jettison its payload fairing at T+3:22 at an altitude of 113 Kilometers, exposing the MOM spacecraft for the remainder of the ascent as aerodynamic forces can no longer damage the vehicle. The fifth firing places the spacecraft in a 600 by 215,000-Kilometer orbit around Earth and sets up the proper perigee passage for the final engine burn that puts the vehicle onto its Trans-Martian Trajectory. Can Americans count on a peaceful transition of political power?
