BREAKING! Mars Orbiter Put In Orbit Successfully!!

[noksss]

The Indian Space Research Organisation is now an established leader in utilitarian space technology -- remote sensing and communication.

It is important for ISRO to take up other challenges that will challenge its limits and expand its capabilities in a worthwhile manner.

Chandrayaan was the first such challenge in which ISRO performed brilliantly.

For example, it established the presence of water on Moon that had only been hinted at by other studies.

MOM is a well organised small (1,500 kg) satellite that can reveal interesting information about Mars and induce us to develop new technology and mission management skills. This is a technology demonstration mission.

The distance between Earth and Mars can vary between 54.6 million kilometre to 401 million kilometre. Even at its closest approach, Mars is like a fast moving Rs 5 coin about one kilometre away. So it is not surprising that many have failed to reach there.

The first technological command we need to demonstrate is that we can undertake complex calculation of sending an object, to a planet that is as small as that. The method that India adopted -- of using the Earth’s gravity to slingshot MOM is a peculiarly Indian approach.

It takes a long time and the timing precision required for it is also demanding but is economical on the fuel used by the satellite.

The next objective is to understand how to send instruments into space with the required precision, make them hibernate for three hundred days and then bring it back to life.

We also need to learn how to make such missions intelligent enough to look after themselves and do what we want them to do on their own, and do it with highest economy, in weight, volume power and intelligence in the harsh space environment.

The sunlight for Mars is also much weaker than on Earth so the power available with the satellite is also limited. Hence the signal from MOM will be extremely faint.

So getting faint signals from the MOM is also a challenge.

In this, the cooperation with NASA has been a great help and we have used NASA deep space network for this purpose.

Even though largely a technology demonstration mission, MOM also carries 5 important instruments.

These include imagers in optical and infrared, a photometer, an instrument to study the impact of neutral material around Mars and a methane sensor. While the imagers will allow us to image the surface of Mars and to determine its surface and atmospheric light reflectivity, the neutral material detector will help us understand how the solar radiation falling on Mars ablates the atmospheric material.

The most watched detector will be the methane sensor. Methane gas is highly reactive and it reacts and changes form quickly.

It can only be sustained by continuing chemical reactions or life forms -- on earth the bacteria from guts of cows are the most prolific producers of methane which is also a greenhouse gas.

There are some tentative detection of methane on Mars. Now MOM will, once and for all, check if those results are true and, if so, what is the location from where the methane is coming.

The overall purpose of all missions to Mars is to study what will be needed to make it habitable.

ISRO can use its superior capabilities in remote sensing to map Mars and see if it can be made liveable, or if life exists below the surface of Mars. So for scientists it is an exciting mission also.

As a scientist therefore I am excited about this demonstration of technology by ISRO, as an Indian I am proud that ISRO has dreamed an impossible dream and made it possible and as a tax payer I am happy that it has done so with so little money.

Yes, I am a proud and happy Indian today, excited that Indians now have clocked their first mission to Mars.

India made history on Wednesday as its maiden Mars mission, Mangalyaan, entered the red planet's orbit

India has become the first country to go to Mars in its maiden attempt. And it has beaten China and Japan to it.
ISRO now joins an elite club of European, US and Russian probes that have managed to orbit or land on the planet. Rediff.com takes a look at spacecraft that have successfully made it to Mars.

The Mariner 4 was launched on November 28, 1964 from Cape Canaveral in the United States.
It was fourth in a series of spacecraft used for planetary exploration in a flyby mode and it successfully flew by Mars on July 14, 1965.
The mission returned the first close-up images of the Martian surface.
The spacecraft was designed to conduct close up scientific observations of Mars and to transmit these observations to Earth.
According to the National Space Science Data Centre, the total cost of the Mariner 4 mission is estimated at $83.2 million.
Mariner 6 and 7 (Launch vehicle - Atlas-Centaur)

The Mariner 6 was launched on February 25, 1969, from Cape Canaveral in the United.
The Mariner 6 and 7 (launched a month later on March 27) comprised a dual-spacecraft mission to Mars. It was the 6th and 7th missions in the Mariner series of spacecraft used for planetary exploration in the flyby mode.
The mission’s objectives were to study the surface and atmosphere of Mars during close flybys. It was also to establish the basis for future investigations, particularly those relevant to the search for extraterrestrial life, and to demonstrate and develop technologies required for future Mars missions and other long-duration missions far from the Sun, according to the National Space Science Date Centre.
Mariner 6 returned 49 far encounter and 26 near encounter images of Mars, and Mariner 7 returned 93 far and 33 near encounter images. Total research, development, launch, and support costs for the Mariner series of spacecraft (Mariners 1 through 10) was approximately $554 million.
Mariner 9 (Mariner I) (Launch vehicle - Atlas-Centaur)

On May 31, 1971, after the first spacecraft, Mariner 8, failed to reach the Earth orbit, Mariner 9, the second in the pair of identical spacecraft was launched.
Mariner 9 became the first spacecraft to orbit another planet. It beat the Soviet Mars 2 (in spite of an 11-day head start) to Mars. The orbiter was able to map 85 per cent of the Martian surface at a resolution of 1 to 2 km in addition to gathering abundant information about the surface and atmosphere.
Images of the Martian surface included the first detailed views of Olympus Mons, the solar system's largest volcano; Valles Marineris, a vast canyon system that dwarfs the Grand Canyon and was named for this spacecraft; the polar caps; and the moons Phobos and Deimos, according to NASA.
It was the first spacecraft to detect water vapor on Mars (over the south pole).
Viking 1 and 2 (Launch vehicle - Titan IIIE/Centaur)

This computer-coloured image was taken by the spacecraft Viking 2 in 1976. Photographs: Image credit: NASA/JPL-Caltech
The Viking Project became the first United States mission to land a spacecraft safely on the surface of Mars and return images of the surface.
Viking 1 was launched on August 20, 1975, and Viking 2 on September 9, 1975. It consisted of two identical spacecraft, each consisting of a lander and an orbiter.
The Viking 1 lander touched down on the western slope of Chryse Planitia (the Plains of Gold), while the Viking 2 lander settled down at Utopia Planitia.
The two landers conducted 3 biology experiments designed to look for possible signs of life. NASA states that while the experiments discovered unexpected and enigmatic chemical activity in the Martian soil, it provided no clear evidence for the presence of living microorganisms in soil near the landing sites.
Mars Global Surveyor (Launch vehicle - Delta 7925)

NASA's Mars Global Surveyor captured this image of 'Happy Face Crater'. This crater is officially known as Galle Crater, and it is about 215 kilometers (134 miles) across. The picture was taken by the Mars Orbiter Camera's red and blue wide angle cameras. The bluish-white tone is caused by wintertime frost. Photographs: Image credit: NASA/JPL-Caltech
After a 20-year gap, the Mars Global Surveyor was launched on November 7, 1996. It was the first successful United States mission to Mars since the Viking mission in 1976.
The Mars Global Surveyor has contributed to a several findings, including signs of past, persistent water such as an ancient delta and currently active water features in the gullies of canyon walls.
The Mars Global Surveyor went silent in November, 2006, nearly a decade of discovery.



Mars Pathfinder (Launch vehicle - Delta II)

In an image released by JPL the Mars Pathfinder mission, a sub-section of the geometrically improved, colour-enhanced version of the 360-degree panorama taken by the Imager for Mars Pathfinder (IMP) over the course of the eighth, ninth and tenth day of the mission.
The Mars Pathfinder was thesecond of NASA's low-cost planetary Discovery missions to be launched on December 4, 1996. The mission’s primary objective was to demonstrate the feasibility of low-cost landings on and exploration of the Martian surface.
Mars Pathfinder was launched on a Delta 7925 (a Delta II Lite launch vehicle with nine strap-on solid-rocket boosters and a Star 48 (PAM-D) third stage)
The bulk of the lander's task was to support the rover by imaging rover operations and relaying data from the rover to Earth. The lander was also equipped with a meteorology station, according to the National Space Science Data Centre.
The Mars Pathfinder mission cost approximately $265 million including launch and operations. Development and construction of the lander cost $150 million and the rover about $25 million.
Mars Odyssey (Launch vehicle - Delta 7925)

The 2001 Mars Odyssey was launched on April 7, 2001, from Cape Canaveral in the United States. It is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the red planet.
The name ‘2001 Mars Odyssey’ was selected as a tribute to the vision and spirit of space exploration as embodied in the works of renowned science fiction author Arthur C Clarke, according to NASA.
Its objective is to conduct a detailed mineralogical analysis of the planet's surface from orbit and measure the radiation environment.
Among other goals, the mission’s primary goal is to gather data to help determine whether the environment on Mars was ever conducive to life.
Mars Express (Launch vehicle - Soyuz-Fregat)

Launched on June 2, 2003, the Mars Express is a European Space Agency mission to Mars.
The mission gets its name Mars Express because it will be built more quickly than any other comparable planetary mission.
It consists of an orbiter, the Mars Express Orbiter, and a lander, Beagle 2.
The scientific objectives of the orbiter are to obtain global high-resolution photo-geology, mineralogical mapping and mapping of the atmospheric composition, study the subsurface structure, the global atmospheric circulation, and the interaction between the atmosphere and the subsurface, and the atmosphere and the interplanetary medium.

MER-A Spirit (Launch vehicle - Delta II 7925) and MER-B Opportunity (Launch vehicle - Delta II 7925H)

Launched on June 10, 2003, the ‘Spirit’ rover is one of the two rovers launched to Mars in mid-2003, (the other was "Opportunity" (Mars Exploration Rover B or MER-1). The rovers arrived at Mars in January of 2004 equipped with a battery of scientific instruments and will be able to traverse 100 meters a day.
‘Opportunity’ was launched on a heavy Delta II 7925H vehicle on July 8, 2003.
NASA states that the scientific goals of the rover missions are to gather data to help determine if life ever arose on Mars, characterise the climate of Mars, characterise the geology of Mars, and prepare for human exploration of Mars.
About 3 hours after landing the first images were returned to Earth, showing a flat plain littered with small rocks. Gusev Crater was chosen as a landing site because it has the appearance of a crater lakebed.
The Mars Exploration Rover (MER) Spirit landed on Mars on January 4, 2004.
Mars Reconnaissance Orbiter (Launch vehicle -Atlas V-401)

The Mars Reconnaissance Orbiter was launched from Cape Canaveral on August 12, 2005, on a search for evidence that water persisted on the surface of Mars for a long period of time.
After a 7-month cruise to Mars and 6 months of aerobraking to reach its science orbit, MRO began seeking out the history of water on Mars with its science instruments.
NASA states that the Mars Reconnaissance Orbiter mission met all its science goals in a two-year primary science phase.
Phoenix Mars Lander (Launch vehicle - Delta 7925)

Launched on August 4, 2007, the Phoenix Mars Lander was designed to study the surface and near-surface environment of a landing site in the high northern area of Mars. The Phoenix Mars Lander was the first mission to explore the Arctic region of Mars at ground level.
The Phoenix mission has officially ended, its last signal was received on November 2, 2008.
Launched from the Kennedy Space Centre aboard a Delta II rocket, the 681 million km heliocentric cruise to Mars took approximately 10 months, with landing on Mars on May 25, 2008.
Cost of the mission is estimated at $417 million.

Thanks

 

[raja hindustani]

Guys ignore our Chinese friend here, and lets continue the discussion. He seems to be particularly upset that India did something that mighty dragon could not ..

Also did anyone see Modi's speech? very inspiring

he made two very important points-

1. It didn't really matter if the mission was successful or not. The scientists need our support and encouragement all the more if the mission didn't succeed.
   
   
2. The comparison with the frenzy with cricket players. He said something to the order of - the achievement of these scientists is 1000x anything cricketers can ever achieve.
