Everyone should relax.

We built PCSAT-2 that was also deployed on the outside of ISS back in 2006.
The requirements for any kind of such EVA hardware are clearly spelled out
by NASA since they (and anyone who thinks about it) realizes that carrying
ANYTHING by hand or on a tether in ZERO G is going to get banged around like
an ape with a suitcase.

It is naïve to assume otherwise.

So PCSAT-2 (and I assume Arissat) was built to be kicked, banged, hit,
dropped, stepped on, and even whizzed on (ISS water releases).  The forces
were specified to include the 300lb impact of the astronauts foot (man and
suit) anywhere and everywhere on the object.

The live video proved how realistic these design requirements are.

So relax.  What you saw is man working in space.  Like making sausage, it
ain't pretty... but its what the laws of physics require when heavy objects

ArissSat was designed for this environment and apparently it survived just
