Freezer, perhaps?

I've cut out a screenshot you took from the L2 RPM images (maybe that's why nasa.gov didn't publish much by way of belly shots) of that damaged tile and added it into the latest article:

http://www.nasaspaceflight.com/2009/03/sts-119-complex-robotics-s6-tps-to-be-cleared/

I heard of no concerns relating to first view of RPM photos, and you'd think that would have included that. Likely just crossing i's and dotting t's, but will follow it up.

Thanks for the image of the damage. But you say they couldn't get any ET photos down so the damage may have been caused by foam, but we'll never know?

Snare problem solved!  GO for grapple!

Just wanted to let you all know that even if the snare cables are out of the groove in either an S-curve or C-curve config we are allowed to go in for a capture.  The snare cycling was shown to clear the C-curves on LEE B during the 15A Pre-launch Checkout ops on GMT 2009-036. After discussions with the various teams involved it was decided to inspect the LEE cavity before every capture for this flight to verify the state of the snare cables.  if they saw any C-curves the crew were to try cycling snares once to attempt to clear.  If the snare cables did not clear then the operator would still have the green light to go in for a capture even with C-curves.  The worst config would be 3 C-curves (today you saw 2 C-curves) and even then there is enough room for the grapple pin to go through the middle.  The envelope is obviously smaller, but the crew operators fly the arm very precisely down so it would probably be ok in the first try.  If not then you try again.

Hope this helps y'all.

Hope this helps y'all.

It does. Thanks for the details. 

Y'know, it still amazes me that 3 small wires and a narrow pin are enough to allow the maneuvering of tens of thousands of kg of hardware at the end of a long articulating arm.

This morning's song:  Johnny Cash's "I Walk the Line!"

Finlay, after 45+ years of space flights, some good wake up song .

In Earth's gravity, that would be amazing.  In weightlessness, obviously...not as much.

Thanks for that info! Very good to know.
