Amazing observation of space debris
Hi all,
I want to share this extraordinary observation regarding orbital mechanics.

Re: Amazing observation of space debris
While the video is interesting, I'm skeptical of the interpretation. A 10m long, 9000kg rocket body rotating radially about a center of gravity 2m from one end (about right given the mass of the motor) at 3 r/s, results in a tensile force that is close to, or exceeding, the material strength of the structure.ralfvandebergh wrote:I want to share this extraordinary observation regarding orbital mechanics.

With so few frames, it is hard to deconstruct what is probably tumbling on two axes. What is needed is a light curve collected at a high rate, for at least 10 or 15 seconds.
Nothing strikes me as unusual or complex about the orbital dynamics, however.

Re: Amazing observation of space debris
I should have mentioned before: I saw the object visually while tracking and i saw it flashing at a very high rate, so I'm very convinced about the interpretation.

Re: Amazing observation of space debris
I wasn't suggesting that there wasn't a ~0.3 second periodicity, only the interpretation that this necessarily means the rocket body is tumbling end over end. The reason for collecting a longer light curve is that it makes it possible to deconstruct the actual tumbling behavior.ralfvandebergh wrote:I should have mentioned before: I saw the object visually while tracking and i saw it flashing at an very high rate, so I'm very convinced about the interpretation.

10 meter long Rocket tumbles around in 0.3 second
Apologies for this new topic which is actually a reworked version of the earlier topic ''amazing observation of space debris''. I have deleted the early version but couldn't edit it with the new link anymore.
