Has any man-made satellite or space vehicle ever been hit by a natural meteoroid?

$begingroup$


For precision I'm excluding artificial meteoroids and satellite debris (which is discussed in another question) of all kinds. I'm also considering collisions large enough to produce a noticeable impact or scar (not truly microscopic dust that can only be detected from wear of the surfaces). Say something carrying at least 1J of kinetic energy.

    If a satellite does not respond to radio signals anymore, how should we know what hapened?

Hypervelocity impacts on the space shuttle Orbiters were analyzed over the years to determine their origin.




After the post-flight inspection is completed, JSC
personnel analyze samples extracted from the impact
sites using a scanning electron microscope (SEM) equipped
with energy dispersive X-ray spectrometers (EDXA). Such techniques
allow engineers to determine whether the impactor was a naturally
occurring meteoroid or man-made orbital debris.




The paper ANALYSIS OF THE NASA SHUTTLE HYPERVELOCITY IMPACT DATABASE breaks down the source of the impacts for various regions of the Orbiter.



The majority of the hits are from debris, but some are attributed to meteoroids. Here's an example, a chart showing the results from the Reinforced Carbon-Carbon areas of the Orbiters (mostly the wing leading edges and nosecap).

    A History of Micrometeoroid and Orbital Debris Impacts On The Space Shuttle lists the "top 20" strikes on space shuttle windows and radiators from 1992 to 2000; most of them are from debris but 4 appear to be from meteoroids. The biggest meteoroid hit appears to be a 5mm hole in a radiator from an 0.7mm meteoroid.

                      Is this a new Fibonacci Identity?

                      Image
                      6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
