Chandrayaan-1 Successfully Reaches 100km Lunar Orbit

Matt_dk writes "Today, Chandrayaan-1 spacecraft has successfully reached its intended operational orbit at a height of about 100 km from the lunar surface. This followed a series of three orbit reduction manoeuvres conducted during the past three days by repeatedly firing the spacecraft's 440 Newton Liquid Engine. The next major event of Chandrayaan-1 mission planned in the coming days is the release of Moon Impact Probe (MIP) from the spacecraft and its eventual hitting of the moon's surface."

      I imagine that's sustained Newtons for the duration of the fuel. So yeah, it's technically a liquid powered engine with the thrust capabilities of an I, but with significantly more fuel. An I engine should be plenty enough for maneuvering a small spacecraft in space.

      The Chandrayaan mission cost India USD 87 million which is just a shade over the cost of a Boeing 737-900ER aircraft (USD 85 million).

    Bouncing a beam off of the lunar laser ranger demonstrates only that we (or more likely the underlings working for the alien overlords known as the Illuminati) planted the device on the moon. It does not prove that it was placed there during the supposed "Apollo" mission nor does it prove that man has ever escaped Earth's orbit or that the moon is in fact real rather than a sophisticated projection on the outside of our fishbowl. There's actually a documentary where OJ Simpson demonstrates how a similar hoax could be pulled off for a manned Mars landing.

    (May the gods help us if anyone interprets the above as anything other than a goofy attempt at humor.)

    Seriously, though, good for the Indians. Considering the $$ that the US has shot into space (development, production, etc), and the continued global interest in space exploration, this could be a very valuable market for them.

Reflected signals were initially received from Lunokhod 1, but no return signals have been detected since 1971, at least in part due to some uncertainty in its location on the Moon. Lunokhod 2's array continues to return signals to Earth."

The whole point of the experiment is to point the beam at the known location - which coincides with the claimed location of a given Apollo landing - and receive the signal. If you do, then someone or something installed the equipment there, and it couldn't be Lunokhod, because it installed its equipment elsewhere (and you can check where it did that, too).
