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.

        "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 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).
