Thanks. This is an informative article about return to flight
planning

Any word on what kind of tests of the tile repair they are planning?
I suppose to fill in some of the routine dings in the tiles which
happen on every mission, so they can see what the repair looks like
after reentry? Or will they stick with something like doing a repair
on a test rig in the payload bay, and bring it back in the payload
bay? (which would test the ability to apply the fix in vacuum, but
which wouldn't give a good idea of how it would fare in reentry).
