Indian craft leaves Earth's orbit on way to Mars

NEW DELHI (AP) — India's Mars orbiter mission left Earth's sphere of influence early Sunday after performing a maneuver to put it on its way to orbit the red planet.

The spacecraft fired its main engine for more than 20 minutes to reach the correct velocity to leave the Earth's orbit, the Bangalore-based Indian Space Research Organization said.

"The Earth orbiting phase of the spacecraft ended. The spacecraft is now on a course to encounter Mars after a journey of about 10 months around the sun," the statement said.

It said that all systems onboard the spacecraft are performing normally.

India launched its first spacecraft bound for Mars on Nov. 5, a complex mission that it hopes will demonstrate and advance technologies for space travel.

The 1,350-kilogram (3,000-pound) orbiter Mangalyaan, which means "Mars craft" in Hindi, must travel 780 million kilometers (485 million miles) over 300 days to reach an orbit around Mars next September.

If the mission is successful, India will become only the fourth space program to visit the red planet after the Soviet Union, the United States and Europe.

Some have questioned the $72 million price tag for a country of 1.2 billion people still dealing with widespread hunger and poverty. But the government defended the Mars mission, and its $1 billion space program in general, by noting its importance in providing high-tech jobs for scientists and engineers and practical applications in solving problems on Earth.

Decades of space research have allowed India to develop satellite, communications and remote sensing technologies that are helping to solve everyday problems at home, from forecasting where fish can be caught by fishermen to predicting storms and floods.

The orbiter will gather images and data that will help in determining how Martian weather systems work and what happened to the large quantities of water that are believed to have once existed on Mars.

It also will search Mars for methane, a key chemical in life processes that could also come from geological processes. Experts say the data will improve understanding about how planets form, what conditions might make life possible and where else in the universe it might exist.

The orbiter is expected to have at least six months to investigate the planet's landscape and atmosphere. At its closest point, it will be 365 kilometers (227 miles) from the planet's surface, and its furthest point will be 80,000 kilometers (49,700 miles) away.

India's Mars mission enters second stage; outpaces space rival China

NEW DELHI (Reuters) - India's first mission to Mars left Earth's orbit early on Sunday, clearing a critical hurdle in its journey to the red planet and overtaking the efforts in space of rival Asian giant China.

The success of the spacecraft, scheduled to orbit Mars by next September, would carry India into a small club, which includes the United States, Europe, and Russia, whose probes have orbited or landed on Mars.

India's venture, called Mangalyaan, faces further more hurdles on its journey to Mars. Fewer than half of missions to the planet are successful.

"While Mangalyaan takes 1.2 billion dreams to Mars, we wish you sweet dreams!" India's space agency said in a tweet soon after the event, referring to the citizens of the world's second-most populous country.

China, a keen competitor in the space race, has considered the possibility of putting a man on the moon sometime after 2020 and aims to land its first probe on the moon on Monday.

It will deploy a buggy called the "Jade Rabbit" to explore the lunar surface in a mission that will also test its deep space communication technologies.

China's Mars probe rode piggyback on a Russian spacecraft that failed to leave Earth's orbit in November 2011. The spacecraft crumbled in the atmosphere and its fragments fell into the Pacific Ocean.

India's mission showcases the country's cheap technology, encouraging hopes it could capture more of the $304-billion (185 billion pounds) global space market, which includes launching satellites for other countries, analysts say.

"Given its cost-effective technology, India is attractive," said Rajeswari Pillai Rajagopalan, an expert on space security at the Observer Research Foundation think-tank in Delhi.

India's low-cost Mars mission has a price tag of 4.5 billion rupees ($73 million), just over a tenth of the cost of NASA's latest mission there, which launched on November 18.


"BIG ACHIEVEMENT"

Homegrown companies - including India's largest infrastructure group Larsen & Toubro, one of its biggest conglomerates, Godrej & Boyce, state-owned aircraft maker Hindustan Aeronautics Ltd and Walchandnagar Industries - made more than two-thirds of the parts for both the probe and the rocket that launched it on November 5.

India's probe completed six orbits around Earth before Sunday's "slingshot", which set it on a path around the sun to carry it towards Mars. The slingshot requires precise calculations to eliminate the risk of missing the new orbit.

"Getting to Mars is a big achievement," said Mayank Vahia, a professor in the astronomy and astrophysics department of the Tata Institute of Fundamental Research in Mumbai.

India's space agency will have to make a few mid-course corrections to keep the probe on track. Its next big challenge will be to enter an orbit around Mars next year, a test failed in 2003 by Japan's probe, which suffered electrical faults as it neared the planet.

"You have to slow the spacecraft down once it gets close to Mars, to catch the orbit, but you can't wait until Mars is in the field of view to do it - that's too late," Vahia said.

India launched its space programme 50 years ago and developed its own rocket technology after Western powers levied sanctions for a 1974 nuclear weapons test. Five years ago, its Chandrayaan satellite found evidence of water on the moon.

By contrast, India has had mixed results in the aerospace industry. Hindustan Aeronautics has been developing a light combat aircraft since the early 1980s, with no success.

The Mars probe will study the planet's surface and mineral composition, besides sniffing the atmosphere for methane, a chemical strongly tied to life on Earth. NASA mission Curiosity did not find significant amounts of the gas in recent tests.

China is still far from catching up with the established space superpowers, the United States and Russia, which decades ago learned the docking techniques China is only now mastering.

Beijing says its space programme is for peaceful purposes, but the U.S. Defence Department has highlighted China's increasing space capabilities, saying it was pursuing ways to keep adversaries from using space-based assets during a crisis.

India's spacecraft successfully begins journey to Mars

India's spacecraft successfully begins journey to Mars

Scientists and engineers of Indian Space Research Organization (ISRO) monitor the Mars Orbiter Mission (MOM) at the tracking centre, ISTRAC (ISRO Telemetry, Tracking and Command Network), in Bangalore, on November 27, 2013



Bangalore (India) (AFP) - India's first mission to Mars left Earth's orbit Sunday, successfully entering the second phase of its journey that could see New Delhi win Asia's race to the Red Planet, scientists said.

The spacecraft, called Mangalyaan, now embarks on a 10-month journey around the sun before reaching Mars in September next year, the state-run Indian Space Research Organisation (ISRO) said.

"The spacecraft is on course to encounter Mars after a 10-month journey around the sun," ISRO said in a statement.

"Following the completion of the latest manoeuvre, the Earth orbiting phase of the spacecraft has ended," it said.

But Mangalyaan, which is travelling at a speed of 32 kilometres (20 miles) per second, could still face hurdles before India joins an elite club of countries to have reached Mars.

India has never before attempted to travel to Mars and more than half of all missions to the planet have ended in failure, including China's in 2011 and Japan's in 2003.

So far, only the United States, European Space Agency and Russia have been able to send their probes to Mars.

NASA launched its unmanned MAVEN spacecraft toward Mars on November 18 to study the Red Planet's atmosphere for clues as to why Earth's neighbour lost its warmth and water over time.

India's Mangalyaan blasted off on November 5 and is using an unusual "slingshot" method for interplanetary journeys.

Lacking enough rocket to blast directly out of Earth's atmosphere and gravitational pull, it was orbiting the Earth until the end of November while building up enough velocity to break free.

ISRO chairman K. Radhakrishnan hailed Sunday's successful operation to slingshot out of Earth's orbit as a "major step" forward in India's low-cost space programme.

"(It is) a turning point for us, as India will foray into the vast interplanetary space for the first time with an indigenous spacecraft to demonstrate our technological capabilities," Radhakrishnan told AFP.

The cost of the project, at 4.5 billion rupees ($73 million), is less than a sixth of the $455 million earmarked for NASA's Mars probe.

Two of the three phases of the Indian Mars mission have now been accomplished, according to ISRO's spaceport director M.Y.S. Prasad.

"The third important phase will be the capturing of Martian orbit in September 2014 for the five scientific experiments," Prasad told AFP from the spaceport of Sriharikota in the southern state of Tamil Nadu.

Mangalyaan is carrying a camera, an imaging spectrometer, a methane sensor and two other scientific instruments to search for signs of life on the Red Planet.

The Mars Orbiter Mission or Mangalyaan was revealed only 15 months ago by Prime Minister Manmohan Singh, shortly after China's attempt flopped when it failed to leave Earth's atmosphere.

The timing and place of the announcement -- in an Independence Day speech -- led to speculation that India was seeking to make a point to its militarily and economically superior neighbour, despite denials from ISRO.

Imagine the entire contents of the planetary datalinks, the sum total of human knowledge, blasted into the Planetmind's fragile neural network with the full force of every reactor on the planet. That is our last-ditch attempt to win humanity a reprieve from extinction at the hands of an awakened alien god.
