Apparently space shuttle Discovery, currently in orbit, had two sensor anomalies from the left wing tip.
Could be thermal flexing, or could be impacts.
EVA planned to inspect for damage.
space.com says first inspection shows no damage

As NASA's Space Shuttle program winds down -- Endeavour's final mission is slated for later this year, then that's it -- let us take a moment and remember the Shuttles.
Space Shuttle mission STS-132 is currently orbiting over our heads. It's scheduled to land a week from now. After that, there's two more launches and that will be that for the program.
It seems to be some damage to the tiles.
Do they have some sort of a tile repair kit with them?
I should add that NASA calls it "minor defects and dislocations", nothing really too dangerous.
As I understand it, the minor defects are on the tiles on the belly of the shuttle and are from separation of the main fuel tank;
the wing ding was an in-orbit event.
One possibility is thermal "pinging", that the carbon panels on the tip flexed from the dark/light transition, the other possibility is micrometeorite or orbital debris impact (latter seems more likely given where they are).
Either way the remote inspection shows no visible holes or damage.
