STEVE INSKEEP, host:
One of NASA's three space shuttles is about to make its final flight. The shuttle Discovery debuted back in the 1980s. This afternoon it's scheduled to liftoff for the space station on its final mission. It is an emotional time for NASA as Discovery will be the first shuttle to be retired. Heres NPR's Nell Greenfieldboyce.
(Soundbite of television show, "This Is Your Life")
Unidentified Man #1 (Announcer): This is your life, a program for all Americans. And now here he is...
NELL GREENFIELDBOYCE: OK. I am not famous TV host Ralph Edwards. And Discovery, you aren't even human. But nonetheless, this is your life. Are you surprised? Don't be. So many people are thinking of you as you get ready for your last trip. Here's one voice from your past:
Mr. HANK HARTFIELD (First commander of Discovery): Everybody calls me Hank.
GREENFIELDBOYCE: That's right, your first Commander, Hank Hartsfield. When he met you, you were just the third in NASA's shuttle fleet. No one knew you'd be special.
Mr. HARTFIELD: Yeah, it was a new vehicle, and, it looked like the others.
Unidentified Man #2: Three, two one, we have SRB ignition and we have liftoff. Liftoff of mission 41D, the first flight of the orbiter Discovery...
GREENFIELDBOYCE: Up and up you roared, soaring to the silence of space. You began to circle our planet, seeing a sunrise and a sunset every 90 minutes. You took a call from President Ronald Reagan.
(Soundbite of recording)
President RONALD REAGAN: Our thoughts and our prayers are with you, believe me, and I say that for myself and Nancy, and I know, for all America.
GREENFIELDBOYCE: So what if he was really talking to your crew. More than 26 years later, the man who commanded that crew, Hank Hartsfield, remembers you fondly, and he has this message just for you.
Mr. HARTSFIELD: I wish I could keep up your wonderful record for at least one more flight.
(Soundbite of music)
Unidentified Man #3 (Singer): (singing) Good morning outer space from all the human race. It's time to stow your sleeping gear.
GREENFIELDBOYCE: Remember that musical wake-up call?
Unidentified Woman: Good morning Discovery.
GREENFIELBOYCE: It's just one of so many songs you heard beamed up from Houston at the start of each day. Your days in space add up to almost a whole year. You're about to make your 39th mission, more flights than any other shuttle.
Ms. VALERIE NEAL (National Air and Space Museum): Discovery is the champion of the shuttle fleet.
GREENFIELDBOYCE: That's Valerie Neal of the National Air and Space Museum. She's got her eye on you, Discovery. She wants to put you in her museum.
Ms. NEAL: Everything that the space shuttle was intended to do, Discovery, and only Discovery, has done.
GREENFIELDBOYCE: You've deployed satellites, including the Hubble Space Telescope, you've done science missions, you hauled up big chunks of the international space station. And both times NASA had its heart broken by a disaster - Challenger and Columbia - you were the first shuttle to return to flight.
Your crews have included a bunch of famous firsts: the first Russian cosmonaut to ride on a shuttle, the first female pilot, the first African American commander. And then there was John Glenn, the first-American-to-orbit-the-Earth, who returned to orbit with you in 1998. A hundred and ninety-four different astronauts have traveled with you. One is Nicole Stott. She'll join you again for your final mission.
Ms. NICOLE STOTT (Astronaut): It is a historic thing, I think, that we have such a special vehicle to fly. And the hope in addition to having successful mission is that, in conclusion, we'll be celebrating just the real significance of the vehicle itself.
GREENFIELDBOYCE: Now, let's face it, Discovery, you did spend most of your life on the ground. Often, like now, you've waited at your launch pad. It has a nice view of the ocean, but you're a little vulnerable out there. Once you got badly pummeled by hail. And remember the time woodpeckers drilled holes all over your fuel tank?
Ms. STEPHANIE STILSON (Kennedy Space Center): Whenever something happens that causes any type of damage or concern with the vehicle, we take that very personally.
GREENFIELDBOYCE: That's Stephanie Stilson, at Kennedy Space Center in Florida. You must recognize her voice. For over a decade, she's led the folks on the ground who tend to your every need. Over and over, these workers nurture you, protect you, and then, amazed, watch you leave the nest.
Ms. STILSON: We really become attached to that orbiter and really consider it almost like a baby.
GREENFIELDBOYCE: She says your final mission makes her sad.
Ms. STILSON: I would love to see Discovery continue to fly, as would everybody else that I work with as well. We all would love to see the shuttle program continue for years and years.
GREENFIELDBOYCE: But the shuttle era is ending. So it's time for you to once again go first, and become the first shuttle to be retired.
(Soundbite of music, Theme from "This is your life")
GREENFIELDBOYCE: This has been your life. It's one you've shared with lots of people. Many of them will be saying Godspeed, Discovery as you blast off towards the stars for the very last time.

Space shuttle Discovery, the workhorse of the shuttle fleet, has carried almost 200 astronauts and numerous science missions to space in its three decades of spaceflight. It launches on its final flight, to the International Space Station, Thursday afternoon.
A space shuttle that has racked up an impressive list of firsts is about to add one more — it will soon become the first in NASA's fleet to be retired.
Space shuttle Discovery made its debut back in 1984, with a satellite-deploying spin through space that included a congratulatory phone call to the crew from President Ronald Reagan. Now Discovery is about to embark on its final mission, marking the beginning of the end of NASA's 30-year-old space shuttle era.
"Am I sad because this is Discovery's last mission? I am. I would love to see Discovery continue to fly, as would everybody else that I work with as well," says Stephanie Stilson of Kennedy Space Center in Florida, who leads the ground crews that take care of Discovery between its flights. "We all would love to see the shuttle program continue for years and years."
But NASA plans to retire its aging fleet this year. Each of the shuttles has just one flight left. After that, they are slated to become museum exhibits. And NASA astronauts will have to be ferried up to the International Space Station first by the Russian space program, then possibly by commercial space companies.
All of this means that Discovery's final flight — scheduled to launch Thursday afternoon — is an emotional time at the space agency. Stilson says that the people who work on Discovery every day have become very attached to it and "really consider it almost like a baby."
Discovery's first commander, Henry "Hank" Hartsfield, recalls that more than 26 years ago, this particular shuttle was just the third in NASA's fleet, joining Columbia and Challenger.
"It was a new vehicle, and it looked like the others," Hartsfield says, but he remembers it fondly and has always paid special attention to its launches. "I watch all of them, but I especially watch Discovery when it goes."
The Workhorse Of The Shuttle Fleet
Columbia and Challenger were both lost in disasters, so Discovery is now the oldest in the fleet. It's also the workhorse, having flown more missions than any other shuttle — its upcoming flight to the space station will be its 39th trip into orbit. Its total days in space add up to almost a whole year, and it has carried 194 different astronauts, according to NASA.
"Discovery is the champion of the shuttle fleet," says Valerie Neal of the Smithsonian National Air and Space Museum in Washington, D.C., which is hoping to get Discovery for its collection. "Everything that the space shuttle was intended to do, Discovery, and only Discovery, has done."
Discovery, she says, has deployed satellites — including the Hubble Space Telescope in 1990 — carried out science missions and hauled up big chunks of the International Space Station.
Over the years, its crews have featured a bunch of famous firsts, such as the first Russian cosmonaut to ride on a shuttle, the first female pilot, and the first African-American commander. What's more, John Glenn, the first American to orbit the Earth, returned to orbit with Discovery in 1998.
And both times that NASA had its heart broken by a major shuttle disaster, Discovery was the first shuttle to return to flight and get the agency back on track.
"It is a historic thing, I think, that we have such a special vehicle to fly," says astronaut Nicole Stott, who flew on Discovery in 2009 and will also be on its final mission. "And the hope, in addition to having a successful mission, is that in conclusion, we'll be celebrating the real significance of the vehicle itself."
Already, Stilson says, NASA has arranged for its workers to have time for special photo opportunities with Discovery. After all, even though its most famous exploits were in space, the shuttle did spend most of its life on the ground, in the care of workers who lovingly tended to its every need.
"We get to put our hands on the vehicle every day; we get to take care of Discovery, make sure that when we do get to a point where we're ready to launch, that it's safe and then very successful for those astronauts who get to borrow it from us for that period of time," says Stilson.
For now, she says, her team is mostly just excited to see Discovery launch and have a successful mission. Even though they know this flight will be the last, she says, "I think the realization will hit more so at touchdown, when we do land Discovery back here."
That's when the members of her team will once again start to get Discovery ready for its next mission — but this time, they'll be getting it prepped not to go into space, but to be an exhibit for a museum.
