India's Chandrayaan 1 enters lunar orbit

The Indian space probe Chandrayaan 1 adjusted its orbit around the moon in one of its final maneuvers before releasing a lunar impactor.

Chandrayaan 1 entered into an elliptical orbit around the moon on Saturday, 17 days after blasting off from Satish Dhawan Space Center in Sriharikota. Yesterday, it fired up its engine to lower its orbit, which now ranges from a high point of about 4,660 miles (7,500 kilometers) to a low point above the lunar surface of 120 miles (200 kilometers). It is now orbiting the moon about every 10 and a half hours.

The Indian Space Research Organization (ISRO), which leads the unmanned mission, says they plan to circularize Chandrayaan 1's polar orbit to about 60-mile (100-kilometer) altitude before dropping its Moon Impact Probe and booting up its scientific instruments.

The impactor will dispatch data back to the mother ship as it takes a suicide dive at the moon. The $80-million Chandrayaan mission carries 11 instruments contributed from an international group of scientists as well as the European Space Agency and NASA. Together, they plan to build a detailed map of the moon's terrain and of its chemical composition.

Chandrayaan 1 is India's first spacecraft to reach the moon and follows on the heels of Chinese and Japanese lunar orbiters that were launched last year.

    Kudos to India for being a little broadminded and making this an international mission with payloads from ESA and NASA. And it is good that a detailed lunar atlas will be created from the mission. Unfortunately, I really don't think this breaks the mold for lunar missions for humanity as a whole. That will only happen when private missions to space and the moon begin. Governments can't help building bureaucracies. That's what they do, regardless of what nation they are from.

    What will have to Chandrayaan after completion of mission, will it come back to the earth or fall on moon?

    Congratulations to all of India for this wonderful achievement.

    It is a proud step forward for India, and it is another proud step forward for humanity as a whole.

    India, China and Japan should all be extremely proud. I hope they have the forethought, pride and challenge to surpass what has become a sense of humiliation for the US. We went to the moon 40 years ago, but now lack the ability and will to return. The US will soon be begging those nations, along with France and Russia for space on their future missions.

    This is for KJeroH. I would like to thank your indirect appreciation.
    I am an Indian. I am definetly proud of our scientists achivements. But, I am certainly disturbed with your comments. Why?
    It is because, we Indians see this in a different light. US space program was started and sustained with the aim to out run Soviets. Our's was started (with the help of US, ofcourse) for helping people. Your statement will make few cynics think that developments by ISRO should be curtailed at all cost. This definetly is not good for us (because in first place) we are not interested in any race.
    Why we are not interested in race is below?
    I may sound naive, but, ISRO is still not looking at surpassing anyone or downgrading any country stature. The organization doesnot have vast resources of NASA or ESA or JAXA or Chinese space agency. So we need to use our resourceses very carefully and only for the purpose which provides maximum output for our masses.

    I don't doubt u'r good intentions, but, yes, by sounding cynic, you are actualling hurting us.
    Special thanks to Theriss for positive appreciation

    I wonder if the Hi-Res pictures will be unaltered? The current atlas of the moon is extraordinarily bad. It has multiple alterations made post-op and are very fuzzy. For them to be considered as suitable for examination is a joke.
    This gent makes, what are to me, accurate conclusions as to the above. His more controversial statements need additional support but are more than mildly stimulating.

    The day is not far off, that, on a fine summer vacation, our great grand children will be enjoying their summer holidays on the Mars and for Christmas / Diwali vacations they may plan to go to Moon.
    India once again proved, that, we are much better than the US.

    Youwill find pockets of water and water ice under the lumar surface trapped there for centuries because with my own eyes 1996 I saw ,naked eye and small scope 40x power, meteor impact at Mons Moro in Mare Cognitum of what I suspect was water ice(white bright) from a comet that week sept 96.I could see it that far away and moving superfast,yet change course as it entered the Moon's gravity well.I'll be looking for those hi res shots in Mare Cognitum when avail. jpl123@inbox.com Jerry in Delaware USA I have Mars info also and pics of people and animals on Mars
