From PBS: Time Runs Out for Telescope, Examining Kepler's Contribution to Space Research
JUDY WOODRUFF: The U.S. space agency confirmed yesterday that its renowned Kepler telescope is beyond repair, a big blow in its search for planets.
The Kepler was launched into an orbit around the sun in 2009, its purpose, observe stars thousands of light years from Earth that may harbor Earth-like planets. By looking at what happens to the light emanated by the stars, it's discovered more than 3,500 possible planets, more than 100 of which have been independently confirmed.
But it has not yet found one planet that has the right conditions for sustaining life as here on Earth. NASA says the spacecraft's wheels, which are critical for keeping it pointed correctly, do not work anymore. Astronomers are now assessing its legacy.
Michael Lemonick is the author of a book about Kepler called “Mirror Earth." He has long written about space and science for TIME magazine.
Michael Lemonick, welcome to the NewsHour.
Tell us a little bit more about what the original mission for the Kepler was.
MICHAEL LEMONICK, author: The original mission was to take a census, really, of a group of stars, an average group of stars, to find out what percentage of them have planets of any kind, and what sizes those planets come in and how far they are from their stars, how the temperature on the surface of those planets would be, if you were there.
JUDY WOODRUFF: And why is that important? And how much of that mission did it get done?
MICHAEL LEMONICK: It got -- well, first of all, it got a huge amount done.
It's important because when -- the reason we look for planets around other stars at all is because we're interested in whether there is life elsewhere in the universe. And the best bet for life, we would think, would be on a planet just like Earth, that is, about the same size as Earth, orbiting a star like sun, with the right temperature for water to exist in liquid form, which is a requirement for life, we think.
And since we know there's a planet like that already in the universe, and life is here, we want to look for a planet like that elsewhere as the best bet for finding life.
JUDY WOODRUFF: And so what happened to the telescope? We mentioned the wheels not working. What -- was this something they expected would go wrong?
MICHAEL LEMONICK: Well, so, these wheels help the telescope point very precisely at the stars it's looking at.
You have to hold the telescope very steady in order to detect the very faint fluctuations in light that happen when a planet goes in front of a star, so it dims just a tiny bit. And the wheels help keep it pointed incredibly precisely. And they have had four of these reaction wheels that the satellite went up with.
One of them failed last year. Another one failed last spring. And with only two wheels still working, you can't point with the accuracy that you need. And so the telescope is still in perfect working order. It just can't aim in the direction that it's supposed to.
JUDY WOODRUFF: Michael Lemonick, it must be incredibly frustrating for the NASA scientists who put so much effort into this. How are they taking it?
MICHAEL LEMONICK: Well, they're actually taking it pretty well. When Kepler was first approved in 2000, it was approved for a four-year mission. That's what the scientists asked for. And NASA said, yes, you can have four years.
And they have completed the four years. In 2012, the scientists said, wow, we could do better science if we had another several years, and they got another three-and-a-half. But the first primary phase of the mission has been completed. And only the first two years worth of data from those four years have been analyzed yet. And those numbers you quoted in the introduction, all those planets it's found already, that's just from the first two years of data.
So they have got two more years' worth to probe through, many more discoveries to make. All they're -- all that is lacking is the ability to then go even deeper and look even further. So they're disappointed, of course. They would have liked to do more with this amazing satellite, but they're incredibly satisfied with what they found already.
JUDY WOODRUFF: But in terms of adding to our understanding of space, you're saying this is significant?
MICHAEL LEMONICK: This is very significant.
What they have done in the survey is discovered what they are convinced are more than 3,000 planets. They haven't all been confirmed yet, but most of them will be. And what they see is that if you look out around average stars, you will see some planets, like Jupiter, big, gassy, giant planets that would be very inhospitable to life, more, smaller planets like Neptune, still not very hospitable.
But as you get smaller and smaller and closer to Earth in size, there are more and more planets. And if they extrapolate from what they have seen, one estimate, one lowball estimate is that in the Milky Way, there would be 17 billion planets with just the right conditions for life, and that's a low estimate. There are probably more than that.
So, we didn't know any of this before Kepler. Now we know that Earth-like planets are almost certainly very common in the Milky Way. Fifteen years ago, we didn't even know there were planets at all around other stars. Now we know that Earths are very common in the Milky Way.
JUDY WOODRUFF: And what do they believe it's going to take to find out where those other Earths are?
MICHAEL LEMONICK: Well, so Kepler's primary mission is often misunderstood.
It wasn't specifically to find those planets in particular. It was to get an idea of how common they are. That's the basic mission. So, if it found that Earth-like planets are very rare, that tells astronomers, OK, maybe it's not worth going out now and trying to find specific ones. What it's found instead is that Earth-like planets are probably very common.
There are probably plenty of them reasonably close to us, and now we can start targeting, with new telescopes, targeting stars closer to Earth than the Kepler stars, which are quite far away, looking for those planets, and, ultimately, with more powerful telescopes, looking at their atmospheres and their surfaces to try and determine whether there's really life there, because it's one thing to say, yes, this is a good place where life could exist.
We want to be able to say, yes, life does exist on these planets. And that is now not a crazy thing to try and do, thanks to Kepler. We now know it's not a quixotic endeavor.
JUDY WOODRUFF: Well, that is pretty exciting.
Michael Lemonick, thank you very much.
MICHAEL LEMONICK: I think so.
Thank you.

Restored Star Trek ship Galileo arrives in Houston
From Yahoo News : Restored Star Trek ship Galileo arrives in Houston
Jeff Langston, 45, drove more than 160 miles from Austin with his two sons to see the moment. He and his 12-year-old son, Pearce, wore matching red Scotty's Repair Shop T-shirts. His 10-year-old son, Neo, couldn't find his shirt, but that didn't put a damper on the moment.
HOUSTON (AP) — When the smoke cleared and the music died down, Candy Torres could no longer contain herself. Looking at the shiny, restored Star Trek Galileo shuttlecraft sitting in Houston in all its TV glory, she broke down.
"All of a sudden I was just crying. I was in tears. I couldn't believe it," Torres said, donning a brown tourist engineer hat and a NASA mission operations shirt. "It meant something."
And Torres wasn't alone. Trekkies of all stripes arrived in Houston Wednesday for the momentous unveiling of the shuttlecraft that crash-landed on a hostile planet in the 1967 "Star Trek" episode called "The Galileo Seven." Some wore Scotty's Repair Shop T-shirts, others full-blown spandex outfits worn by Mr. Spock and his peers in the famous TV show and movies that have garnered a following so large and so devoted it is almost cult-like.
Adam Schneider paid $61,000 for the battered shuttlecraft in an auction and spent about a year restoring the fiberglass ship and making it look nearly as it did on that episode. He flew in from New York to mark the unveiling at the Space Center Houston, where it will be permanently displayed not far from NASA's Mission Control.
"Unbelievably proud," he said, beaming alongside the white shuttle. "Like sending your kid to college and having them get a job to build a successful life, because this was under our care for a year and we grew very attached.Jeff Langston, 45, drove more than 160 miles from Austin with his two sons to see the moment. He and his 12-year-old son, Pearce, wore matching red Scotty's Repair Shop T-shirts. His 10-year-old son, Neo, couldn't find his shirt, but that didn't put a damper on the moment.
"It was very exciting," Neo said, bouncing on his feet. "When they filmed Star Trek the Galileo was cool and now that they remade it, it's cool to see a new version of the Galileo. And it's beautiful."
Richard Allen, the space center's 63-year-old CEO and president, hopes that just as the Star Trek movies and others like it inspired Torres to pursue a career in science and engineering, that today's generation will be similarly inspired when they see the Galileo.
"It's fantastic," he said of the shuttlecraft. "We're all about exciting and educating ... and I'm convinced that space is one of the best, if not the best, way of creating inquiry in young minds."

Showdown over NASA funding likely
From USA Today: Showdown over NASA funding likely
WASHINGTON — A Senate panel Tuesday narrowly approved a bill reauthorizing NASA, setting up a showdown with the House over how much money the nation's space program should get.
The three-year bill, which now heads to the full Senate, would give the space agency $18.1 billion in fiscal year 2014, $18.4 billion in 2015 and $18.8 billion in 2016 -- $2 billion more per year than the U.S. House is considering. NASA received $17.7 billion in fiscal 2013, which ends Sept. 30.
The Senate Commerce, Science and Transportation Committee passed the bill 13-12 along party lines, with Democrats in favor and Republicans opposed.
"While it's not as much as we'd like NASA to have, it's certainly a step in the right direction," Sen. Bill Nelson, D-Fla., said after the vote. Nelson chairs the Science and Space Subcommittee that helped shape and steer the legislation.
If the Democratic-led Senate passes the bill as expected, lawmakers likely will have to reconcile it with a House bill that promises NASA much less. Earlier this month, lawmakers on the GOP-led House Science, Space and Technology Committee settled on a funding figure closer to $16.8 billion for fiscal 2014 and fiscal 2015. A vote on the House floor is expected later this year.
The partisan conflict over NASA funding largely involves each party's view of how much money is available to spend on most federal programs, such as space and science.
Republicans are unwilling to go beyond the overall allocations spelled out in the budget they approved earlier this year. Those levels assume the government-wide budget cuts Congress agreed to in 2011 -- known as sequestration -- will remain in effect.
Democrats on the Commerce, Science and Transportation Committee argued Tuesday that NASA reauthorization should be based on how much money the agency realistically needs, not on what might be available in the next budget cycle.
Sen. Maria Cantwell, D-Wash., called a Republican amendment to reduce the bill's funding levels "a misguided attempt to really turn the committee into nothing but the Appropriations (Committee)."
"And I think we have very important technology-mission oversight that we have to focus on," she said.
South Dakota Sen. John Thune, the top Republican on the panel, sounded optimistic that lawmakers can compromise.
The NASA bill "will likely need even more work before (it) reflects the kind of consensus that has characterized our committee's enacted legislation," he told panel members. "With additional effort, however, I am hopeful that we can get there in the weeks and months ahead."
The difference is not just about money. It's also about NASA's overall direction and whether the agency should be allowed — or trusted — to pursue the course it's laid out for the next few years.
Both the House and Senate measures would provide money to continue developing NASA's top priorities: a deep-space mission to Mars, a joint venture with aerospace firms to ferry astronauts to the International Space Station, and completion of the James Webb Space Telescope.
But while the Senate bill would permit an asteroid retrieval mission the agency wants to undertake as part of its stepping-stone approach to Mars, the House measure strictly prohibits it.
"I don't think that is the position of a committee to be telling the scientists and the NASA experts of what we should be doing," Nelson said Tuesday.

Take your blood pressure medication!
Spent most of yesterday in the hospital, where my mother was admitted. Her doctor had changed her blood pressure medication a couple of weeks ago, it wasn't doing the job. Unfortunately her doctor was out of town and a home therapist said we should take her to the Emergency Room.
Bad idea, as far as I'm concerned. Put her back on her old medication which was working, just causing her to cough.
Instead we brought her to the emergency room, and since she's old and deaf, this got her more stressed out and scared than ever, because they were all gathered around her shouting questions and wanting to run tests and I'm sure she thought she was dying or something, which sent her blood pressure even higher.
She spent the night there, and is still in today for more tests, which I don't think she needs but I guess since they've got her in there they want to get their money's worth out of our insurance... she's in a private room which must be costing a fortune....
The reason for my headline... she was about 40 when she was first diagnosed with high blood pressure...took pills for a couple of days but didn't like how they made her feel....so she stopped taking them and tried to do the "natural remedy" thing.
Result, 20 years later she had congestive heart failure, and now instead of taking 1 pill a day she has to take 4. And has to go into the hospital periodically on occasions like these.
Moral of the story - go get your blood pressure checked, and if you have high blood pressure make sure you take your meds, otherwise believe me you'll wish you had, when it is too late...

How Video Games Help Fuel Space Exploration
From Space.com: How Video Games Help Fuel Space Exploration
Having traveled to other worlds in his game creations such as "Ultima," Richard Garriott de Cayeux is now doing the real thing. He flew to the International Space Station in 2008 (on a reported $30 million ticket). And his company, Space Adventures, has organized flights on Soyuz craft for about a dozen other moguls.
At the South by Southwest conference in Austin this week, Garriott de Cayeux explained why he thinks that private companies can make spaceflight radically cheaper and more common. Ideas include having NASA contract with private rocket companies for human spaceflight instead of building all its own craft (which it already does to launch robots such as the Mars Rover Curiosity). Garriott de Cayeux also promotes reusable spacecraft, which he claims offer tenfold to hundredfold cost savings.
Elon Musk of SpaceX, the most successful extraterrestrial entrepreneur so far, is testing reusable technology
called Grasshopper. And so is John Carmack, creator of blockbuster video game franchises "Doom" and "Quake." His company, Armadillo Aerospace, is focused on building reusable craft.
TechNewsDaily asked Garriott de Cayeux why game creators are attracted to spaceflight. "If there was something specific to the games industry, it would have to be from exploring virtual
worlds," he said. "It would have to be … creating experiences that let people go into the unknown. Noting his many adventures, including into space, to Antarctica and to the bottom of the ocean, he said, "I find my drive to go explore is identical and very closely linked with my personal drive to create things for people to explore."
But the images in many games may not be the best thing to motivate future generations of explorers, said astronaut Mae Jemison. In a panel session, she spoke about the 100 Year Starship Project she leads, which aims to kick-start the technologies
to make interstellar spaceflight possible within a century.
Many of the most popular video games over the years, including "Doom" and "Quake," are also very violent. "I'm struck by the fact that we have all the slasher, blood-and-guts, shoot-'em-up movies and stuff like that," Jemison said. "It doesn't make you very hopeful for the future."
Jemison's fellow panelist Jill Tarter of SETI (Search for Extraterrestrial Intelligence) said that games could be helpful, "to the extent that people can … build interactive experiences that aren't always shooting and competitive."
LeVar Burton of "Star Trek" fame, also on the panel, told TechNewsDaily that he was excited about the use of biofeedback in games. "I can certainly imagine games that are … first-person experience, where you really have to be in a calm and imaginative state in order to advance in the gameplay," he said. "And I think that's a lot more productive in terms of entrainment than … the first-person shooter." [See also: Video Games Improve Surgeons' Skills]
Jemison also sees games as a way to study how people interact, which is critical to creating livable conditions for a space mission that will span entire lifetimes. Games, she said, could help to, "ferret out some information about human behavior."
Burton agreed: "Using gameplay to problem-solve — fantastic use of the technology."
