The hole in the ozone layer is stabilizing but will take until about 2070 to fully recover, according to new research by NASA scientists. The assessment comes more than two decades after the Montreal Protocol , the international treaty that banned chlorofluorocarbons and other compounds that deplete the ozone layer, which shields the planet from harmful ultraviolet rays. Levels of chlorine in the atmosphere are falling as a result of the treaty, but have not yet dropped below the threshold necessary to have a shrinking effect on the ozone hole that forms each year over Antarctica, according to scientists at NASA's Goddard Space Flight Center.

A quirky habit of German insomniacs and "chill-out" music fans has come to world attention thanks to the U.S. government shutdown. "Space Night," a nearly 20-year-old late-night broadcast by Bavarian Television, provides a music-sharing platform against a backdrop of NASA's video feed from the International Space Station. But the 15-day-old U.S. government shutdown has idled the NASA archivists responsible for relaying the imagery beyond Mission Control, cutting off fresh backdrops to mix with the music for "Space Night" broadcasts that were to have launched a new season Nov. 1. NASA archivists were put on unpaid leave at the start of October, when 700,000 government workers whose jobs weren't deemed essential to defense and security were furloughed until the contentious U.S. Congress passes a budget for the new fiscal year.

This Earth Day NASA is asking citizens of the Earth to step outside and photograph themselves wherever on the planet they happen to be. The space agency's celebration of the Earth and the people who live on it is called, appropriately, #globalselfie. To participate all you need is a digital camera and a sign indicating which spot on our planet you happen to be standing on. (Not feeling creative? NASA has a sign you can print out on its website. It reads, "Hi NASA! I'm on Earth Right Now @_______)

Charles used to work at NASA and wants to stay in touch with the space program via NASA TV, the cable channel paid for by tax dollars and provided free to telecom companies. Turns out, though, that his AT&T U-verse package doesn't include NASA TV. To receive the channel, he was told, he'd have to pay for a more expensive programming package. More videos from Ask Laz Charles' question: Why should NASA TV be considered a premium channel considering that taxpayers have already paid for it?

NASA wants to send haikus to Mars, and you - yes, you! - might be just the poet for the job. The space agency plans to launch a spacecraft to study the upper layers of the Red Planet's atmosphere in November. But before the Mars Atmosphere and Volatile Evolution mission (known as MAVEN) blasts off, NASA is asking the public to submit their names for a DVD that will be loaded onto the Martian satellite. If you missed your chance at getting your name engraved on microchips on the Mars rover Curiosity (along with the names of 1.2 million other people)

NASA reached outside its own organization today and appointed an industry expert as the head of a new safety office to guard against a repetition of the Challenger disaster. George A. Rodney, director of mission success at the Martin-Marietta Orlando Aerospace Co. in Florida, will have charge of all safety, reliability and quality assurance functions in NASA activities.

Bake sales at high schools to raise money for trips to Washington, D.C., football uniforms, art supplies and the like are commonplace in these tough budgetary times. But a bake sale for NASA planetary science? On Saturday, scientists from Caltech and UCLA will be out in force at La Canada High School, with chocolate chip cookies and brownies on hand, as part of a nationwide Planetary Bake Sale that is intended to raise awareness of proposed cuts to the NASA science budget.

Having trouble getting excited about NASA's planned mission to redirect an asteroid? Maybe William Gerstenmaier can help. "Turn off your logical side and turn on your touchy-feely side, the one you almost never use," Gerstenmaier, associate administrator for NASA's Human Exploration and Operations Directorate, told attendees of an aeronautics and astronautics conference Wednesday in San Diego. "Then jump up and down and do some break-dancing. We're going to grab a space rock and we're going to move it!"

Last summer astronaut Luca Parmitano came perilously close to drowning in space after more than a liter of water leaked into his helmet. Today NASA officials said they are still trying to figure out what went wrong. The near-drowning occurred July 16 about one hour into Parmitano's second spacewalk. Forty-four minutes into the walk, the Italian astronaut noticed the back of his head was wet. Ten minutes later he reported the amount of water was increasing. By the time mission control decided to abort the mission 23 minutes later, large droplets of water were starting to cover Parmitano's eyes, nose and ears as he made his way toward the air lock.

What happens to our DNA, RNA and proteins if we spend a long time in space? A pair of 50-year-old twins will help NASA find out. Identical twins Mark and Scott Kelly have signed up to be part of the first-ever twin study that takes place, at least partially, in space. In March 2015, veteran astronaut Scott Kelly will begin a one-year stint living aboard the International Space Station. It will be the longest amount of consecutive time that any American astronaut has spent in space. His brother Mark Kelly, who is married to former Arizona Rep. Gabrielle Giffords, will stay on Earth and serve as a control in the study.
