India reaches Mars: Why it matters

More than half of all Mars missions fail, but India's Mars Orbiter Mission was not one of them, an extraordinary feat for a mission that began just three years ago.

Space history was made today when India鈥檚 car sized聽聽(MOM) successfully聽聽and arrived in Mars orbit today (Sept. 23 EST/Sept. 24 IST) on the nation鈥檚 first attempt to聽. Indeed MOM is India鈥檚 maiden interplanetary voyager and 鈥渃reated history.鈥�

India thereby joins an elite club of only three other entities who have launched probes that successfully聽- following the Soviet Union, the United States and the European Space Agency (ESA).聽

Wild applause erupted with beaming smiles from ear to ear at India鈥檚 Bangalore mission control center after signals confirming a successful full duration firing of the crafts engines for 24 minutes and 13 seconds for the crucial Mars Orbital Insertion (MOI) maneuver that placed MOM into orbit, were received precisely as planned at 10:30 p.m. EDT (Sept 23) or 8:00 IST (Sept. 24).

Traveling at the speed of light it took nearly 12.5 minutes for the good news signals to arrive on Earth from Mars across the vast expanse of some 140 million miles (225 million kilometers) of interplanetary space.

MOM鈥檚 Red Planet arrival was webcast live worldwide by the Indian Space Research Organization (ISRO), India鈥檚 space agency which designed and developed the orbiter.

ISRO鈥檚 website also gave a play by play in real time, announcing the results of critical spacecraft actions along the arrival timeline just moments after they became known.

鈥淚ndia has successfully reached Mars!鈥� declared Indian prime minister Narendra Modi, who watched the events unfold from mission control at ISRO鈥檚 Telemetry, Tracking and Command Network (ISTRAC) in Bangalore.

鈥淗istory has been created today. We have dared to reach out into the unknown and have achieved the near-impossible. I congratulate all ISRO scientists as well as all my fellow Indians on this historic occasion.鈥�

Modi gave a stirring and passionate speech to the team, the nation and a global audience outlining the benefits and importance of India鈥檚 space program. He implored the team to strive for even greater space exploration challenges, sounding very much like US President John F. Kennedy over 50 years ago!

鈥淲e have gone beyond the boundaries of human enterprise and imagination,鈥� Modi stated. 鈥淲e have accurately navigated our spacecraft through a route known to very few. And we have done it from a distance so large that it took even a command signal from Earth to reach it more than it takes sunlight to reach us.鈥�

The do-or-die MOI breaking maneuver slowed MOM鈥檚 velocity by 1099 m/s (2457 mph) vs. an expected 1098.7 m/s 鈥� using the combined thrust of the 440 Newton Liquid Apogee Motor (LAM) main engine and eight smaller 22 newton liquid fueled engines.

The entire MOI maneuver took place fully autonomously under the spacecrafts preprogrammed sole control due to the long communications lag time and also during a partial communications blackout when the probe was traveling behind Mars and the signal was blocked.

MOM鈥檚 goal is to study Mars surface features, morphology, mineralogy and the Martian atmosphere with five indigenous scientific instruments. Among other goals it will sniff for methane as a potential marker for biological activity.

MOM鈥檚 success follows closely on the heels of NASA鈥檚 MAVEN orbiter which also successfully achieved orbit barely two days earlier on Sept. 21.

Modi noted that more than half of all missions to Mars have failed.

鈥淲e have prevailed. We have succeeded on our first attempt. We put together the spacecraft in record time, in a mere three years from first studying its feasibility,鈥� Modi elaborated.

鈥淭hese are accomplishments that will go down in history. Innovation by its very nature involves risk. It is a leap into the dark .. . and the unknown. Space is indeed the biggest unknown out there.鈥�

鈥淭hrough your brilliance and hard work [at ISRO] you have made a habit of accomplishing the impossible.鈥�

鈥淭he success of our space program is a shining symbol of what we are capable of as a nation. Our space program is an example of achievement which inspires us all .. and future generations 鈥� to strive for excellence ourselves.鈥�

鈥淪pace technology translates to space applications here on Earth 鈥� to improve the life of our citizens.鈥�

鈥淟et us set ourselves even more challenging goals and strive even harder to achieve them. Let us push our boundaries. And then push some more, and push some more!鈥� said Modi jubilantly.

MOM now joins Earth鈥檚 newly fortified armada of seven spacecraft currently operating on Mars surface or in orbit 鈥� including MAVEN, Mars Odyssey (MO), Mars Reconnaissance Orbiter MRO), Mars Express (MEX), Curiosity and Opportunity.

鈥淢OM and MAVEN will keep each other company in orbit,鈥� said Modi.

Today, MOM concluded her over 10 month interplanetary voyage of some 442 million miles (712 million km) from Earth to the Red Planet.

鈥淐ongratulations to the MOM team on behalf of the entire MAVEN team! Here鈥檚 to exciting science from the two latest missions to join the Mars fleet!鈥�, wrote Bruce Jakosky, MAVEN Principal Investigator, in a post on the ISRO MOM facebook page.

MOM was launched on Nov. 5, 2013 from India鈥檚 spaceport at the Satish Dhawan Space Centre, Sriharikota, atop the nations indigenous four stage Polar Satellite Launch Vehicle (PSLV).

The flight path of the approximately $73 Million probe was being continuously monitored by the Indian Deep Space Network (IDSN) and NASA JPL鈥檚 Deep Space Network (DSN) to maintain its course.

鈥淭he events related to Mars Orbit Insertion progressed satisfactorily and the spacecraft performance was normal. The Spacecraft is now circling Mars in an orbit whose nearest point to Mars (periapsis) is at 421.7 km and farthest point (apoapsis) at 76,993.6 km. The inclination of orbit with respect to the equatorial plane of Mars is 150 degree, as intended. In this orbit, the spacecraft takes 72 hours 51 minutes 51 seconds to go round the Mars once,鈥� according to an ISRO statement.

MOM is expected to investigate the Red Planet for at least six months.

Although MOM鈥檚 main objective is a demonstration of technological capabilities, she will also study the planet鈥檚 atmosphere and surface.

The probe is equipped with five indigenous instruments to conduct meaningful science 鈥� including a tri color imager (MCC) and a methane gas sniffer (MSM) to study the Red Planet鈥檚 atmosphere, morphology, mineralogy and surface features. Methane on Earth originates from both geological and biological sources 鈥� and could be a potential marker for the existence of Martian microbes.

Both MAVEN and MOM鈥檚 goal is to study the Martian atmosphere , unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost 鈥� and how this transformed Mars climate into its cold, desiccated state of today.
