India’s first lunar mission has ended not with a bang, but with dead silence. India’s space agency lost contact with the lunar orbiter, Chandrayaan-I, over the weekend; when efforts to restore communication were futile Indian officials declared that the mission was over.
The launch of Chandrayaan-1 in October 2008 put India in an elite club of countries with moon missions. Other countries with similar satellites are the United States, Russia, the European Space Agency, Japan and China [AP]. Indian officials hope that either NASA or the Russian space agency will agree to track the orbiter, which is currently circling 125 miles from the moon’s surface. The satellite’s orbit will slowly decay over the next several years, and it is expected to crash into the moon in about 1,000 days.

Today the entire nation of India rejoiced as the nation’s first lunar orbiter send an impact probe smashing into the moon’s surface. As the probe was painted with the jaunty tricolor flag of India, millions of ecstatic citizens saw it as a near equivalent to Neil Armstrong and Buzz Aldrin’s planting of the American flag on lunar soil almost 40 years ago. “Just as we had promised, we have given India the moon,” said G. Madhavan Nair, Chairman of the Indian Space Research Organisation [The Hindu].
Lunar orbiter Chandrayaan-1 — Chandrayaan means “moon craft” in Sanskrit — was successfully launched from southern India on October 22 and is now orbiting the moon. Its two-year mission is to take high-resolution, three-dimensional images of the moon’s surface, especially the permanently shadowed polar regions. It also will search for evidence of water or ice and attempt to identify the chemical composition of certain lunar rocks [CNN]. The Indian government has said that the $79 million mission to map the lunar surface is just a prelude to the landing of a robotic lunar rover in 2012, and a manned mission to the moon by 2020.

Researchers have gotten a close look at a lunar crater that was thought to hold “skating rinks” of ice, and have reached the disappointing conclusion that the crater does not have visible patches of water ice after all. New images from the Japanese lunar orbiter, Kaguya, reveal no traces of ice in the Shackleton crater, a cold and shadowy place near the moon’s south pole. Ice would be vital for future colonies on the Moon, providing drinking water for astronauts and hydrogen fuel for their vehicles [New Scientist].
Researchers had high hopes for the Shackleton crater because it never receives direct sunlight. The theory was that if comets have landed there (and, given the craters’ ages, the odds are that several will have), some of the ice carried by such dirty celestial snowballs might be preserved in the permanent shadow cast by the craters’ walls [The Economist]. Then NASA’s 1998 Lunar Prospector detected an excess of hydrogen at the moon’s poles, which researchers thought indicated the presence of water ice.

Early tomorrow morning, India will launch its first lunar satellite, making it the sixth country to do so, following the United States, Russia, the European Space Agency, China, and Japan. The lunar-orbiting spacecraft, Chandrayaan-1, is scheduled to blast off aboard an Indian-built rocket at 6:20 am (0050 GMT) on Wednesday from the Satish Dhawan Space Centre in Sriharikota on India’s southeastern coast [AFP].
If all goes to plan, the satellite, weighing half a [metric] tonne, will enter a lunar orbit some 62 miles above the moon’s surface on November 8 and begin its two-year mission to map the moon in 3D, survey its surface for mineral wealth and start its 11 hi-tech probes, including five from the US, Sweden, Japan, Germany and Bulgaria [Guardian] Specifically, Chandrayaan-1 will be looking for uranium, helium-3 (used for nuclear fusion), and water ice. Although the unmanned spacecraft itself will not land on the moon, it will eject a small craft to land on and investigate the lunar surface.

An international group has given India special approval to buy nuclear technology to further its nuclear power program, although the country has steadfastly refused to sign the nuclear non-proliferation treaty. The decision, made by the 45-nation Nuclear Suppliers Group (NSG), was strongly supported by the United States, which hopes to sell the technology to India. The NSG adopted a one-off waiver of a 34-year-old global ban on nuclear trade with India, allowing New Delhi and Washington to do business [Reuters].
The proposed deal between the United States and India still has to be approved by the U.S. Congress, and there are several roadblocks to its immediate passage. Congress will be in session for only two weeks this September before breaking again for the final flurry of campaigning before the November election, and supporters of the India deal will have to pass special legislation to expedite the approval process. ‘‘I’d say the chances of it getting past the senate are 50-50,” a Senate aide said. ”Senators are good at tying things up in knots” [Times of India].
