Some good stuff, and a lovely comment from Kenn Ham.
On Atlantis' "final" mission:
Kenn: "There is potential for her to fly again, but she's served us well. We thank the entire team for putting her together to fly for us."
On ISS after shuttle:
"We'll need to learn how to best manage resources" (whilst noting more vehicles will come up. There's a lot of spares on board, there's not a lot of items outstanding that require the shuttle payload's size."
Question about oil slick.
Piers: "Been too busy to see it, but when you get to travel around the planet you get to see the footprint of man, some of it good, some of it bad. People will eventually get to look after the planet."
What's that on your leg? (checklist)
Piers: "It's my brain"

About what they'll tell the kids on their acomplishments:
"There's nothing like it. Spacewalking is the most outlandish thing I've got to do. I'm 5ft 4in and they laughed at me when I said I wanted to do spacewalks. Steve had the lion's share of the tasks. We had some difficult moments, but the sense of elation when we fixed it is something I'll always remember."
Great work from MSNBC.
