with all due respect to the late carl sagan, (bleep) you carl sagan. (laughter and applause) it's painful or me to witness the dismantling of the space flight program. >> the "discovery" is piggybacking to its new home in washington, d.c., the smithsonian institute. >> "discovery", the oldest of the three remaining orbiters flew 39 missions, 148 plus million miles. >> bad, too, because we won't see it again. >> stephen: it's more than sad. it's embarrassing to see the old shuttle caught on camera getting petty sex from a 747. (laughter) that, folks, that is not even the nastiest. they have also announced they are decommissioning space book, the social networking site for nasa employees. we have lost the space book race! (laughter) this is the worst news in interstellar social network since the downfall of my myspace.com. (laughter) according to an internal nasa memo, participation been as high. on average, only 14 users log in per weekday and zero on the weekend. yes, space book averaged zero users on the weekend. some weekends three users logged in, o

"something somewhere is waiting to be known" -- carl sagan. >> "live life to the fullest." i'm not sure where that's from. i assume it's a general saying. >> "it's not about waiting for the rain to pass. it's about learning to dance in the rain," 'cause it's like you shouldn't wait -- technically, it's not like you should wait for opportunities to come. like, you should just go for them. >> "with power comes great responsibility." >> well, i always liked saying, "no day but today," about, like, living and taking advantage of the moment. >> "if you don't have something to nice to say, say it in yiddish." >> if you haven't found an adage, maxim, or aphorism to call your own, try this one from eleanor roosevelt... i like that. for "teen kids news," i'm emily. >> troy has some information that might surprise you about how much is enough of a good thing. [ chomp! ] >> it's not enough to just eat the right foods. you also need to know the right amounts. that's called portion control. nutritionist jax hubbard can show us what a normal serving should look like. >> well, it's always

the reason was i was watching carl sagan on the charlie rose show in the 1990s. he announced that he had had his second or third own marrow transplant because of a cancerous disease he had. it saved his life. he had been saved by science. my wife looked at me and said, wow, he's going to die, and soon. and i said why do you think? >> this is the denial speech. she had cancer and she was in support groups. this is a speech who are given by those who are pronounced terminal. the show finished, and they announced that it had done everyone. that he had died. he had been taped a couple months earlier, and the man who had been saved by science was dead. he said an interesting thing in his show, which rose had asked him. he said what do you think that is? death is a long, dreamless suite. i thought well, that can be. sleep is pleasant. you are breathing, no chemical. [inaudible] is going on. this is one of the greatest skeptics of our age. and he thinks he's going to be sleeping. what i wanted to do was try to find out what science said about that the motor was. i start

the person originally scheduled to write that was carol s -- carl sagan. he had been asked to contribute a chapter to that volume. he had been ill, he died in 1996. my name was put up as one who would then write in his stead. and i was honored to be asked, although the size of the project was bigger than what i was really accustomed to. at the time i was writing monthly columns for "natural history" magazine coming in the at 2 or 3,000 words. that's pretty much what i could pump out in a month. this chapter was asked of me to be 10,000 words, and i just -- so i almost declined. and then i said, no, maybe i can do something different, a little more creative. and i thought, okay, why not, why not think of discovery not in the 20th century, not even in terms of the discovery of objects of places, but maybe the discovery of ideas. and i would track the transition from the discovery of places going back to the era of the great explorers to the score of ideas -- discovery of ideas. once you've mapped the whole earth, what is left for you to discover? yes, there'

he is more popular in the uk than carl sagan ever was here in america. there is, in fact, hope for this world. and it's represented by the electorate, not by our elected officials. [applause] in my humble opinion. yes, sir. >> good evening. the way i see it, the 20th century belongs to america and russia, as well as space exploration. and now that i look at the international space station, i see that as one effort that has been some collaboration at the international level. you talk a lot about war and economies of the motivations for countries do it alone. but what about cooperation globally? when china, india, japan, russia, america, we don't all go in the same direction, but come together to do something, a grand vision so to speak. and despite being a very big skeptic of u.n. and how the international system of functions, but is there some hope for us? >> the international space station is the greatest collaboration of nations, other than the waging of war. in terms of the size, the scale, the investment, the number of nations that participate. so it
