Chandrayaan-1 Successfully Reaches 100km Lunar Orbit 152

Posted by timothy
from the what-hath-man-wrought dept.
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.

      i doubt its either

      for a start the measurement in the summary is in newtons not newton seconds like in the wiki article, so in theory it could be any of those depending on how long it lasts, i.e 440N for only 0.005s would be an A motor, also the wiki article looks to be for rocket motors, not for controlled thrusters, so in all likelyhood, your question is nonsense, sorry
    • You can't tell from TFA. 440 newtons (actually probably the 103 lbs IHI biprop) is the thrust, not the total impulse.

    So when America returns to the moon, they can look forward to a variety of tasty lunar takeout joints already established by the Indians and Chinese. The resulting outbreaks of explosive diarrhea can be put to good use in terraforming the moon.

      Mind you it's lucky the Americans haven't set up base permanently, otherwise none of the astronauts who visited would be able to get back into their spaceships and come back. They'd all be too obese to fit through the hatches of their lunar modules from eating the high quality cuisine the USA has given the world, supersized burgers and fries washed down with gallon buckets of coca-cola... ;-)

        They went to an observatory and had the person show that pointing the laser away from the moon produced no return signal whereas when they pointed the laser at a specific spot on the moon, they did get a signal.

        Not to call doubt upon the Moon landing, but retroreflectors have been placed on the Moon as part of the unmanned Lunokhod program [wikipedia.org]. According to the link you posted:

        "The unmanned Soviet Lunokhod 1 and Lunokhod 2 rovers carried smaller arrays. 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."

          Lunokhod 2 reflector array is in the location different from the Apollo ones. 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).

      That is actually less than half of what the chinese spent (USD 180+ million).
