Fengyun 1C debris a threat to EVA
With the recent news that the tracked debris count from F1C has risen to over 300 pieces .... and unofficial
estimates that there may be tens of thousands of bits out there , I'm wondering what level of threat this poses to the forthcoming EVAs ?
At least one piece of debris has already come within a few kilometres of the station. Does anyone know if there are any contingency
measures in place to minimise the risk to the crew ?

Yes , seen that , I'm a regular contributor to SeeSat-L and we have been discussing the debris situation since the event.
What is interesting is that there doesn't seem to have been an official statement from NASA regarding any possible
threat to ISS.....unless I have missed it.

As predicted ISS has had to change orbit to avoid debris from the destroyed

Tomorrow a second spacewalk ( of three ) will take place
The anti meteorite system on board ISS may protect the spacecraft , but not
the crew "outside" !

Or does it............... ???
It appears that the story about the orbit change was incorrect.....
"Lost In Translation."
It seems the original story should have said that ...... ISS can change orbit to avoid space debris......but not that it "has"
In other words "if" it needed to move to avoid Fengyun 1C debris it could , but so far that hasn't been necessary !
Pehaps its time NASA made a formal statement about the debris situation...does it present a real danger or not? Predictions still
indicate that it does.
To keep an eye on the short term situation , go to SOCRATES http://celestrak.com/SOCRATES/ and in the search section , type
in Fengyun 1C , it will list all the predicted orbital conjuntions , including ( if any ) those with ISS.
