Space: Final Frontier

The investigation into last month's scary landing by a Russian Soyuz spacecraft is still going on, but another Soyuz at the International Space Station is off the hook, so NASA has cleared the Discovery shuttle for launch on May 31, the Orlando Sentinel reports. The shuttle is expected to attach a huge Japanese lab to the ISS. More »

If a comet ever obliterates life on Earth, don't worry—space rocks could later fall in and reseed a few basic life forms. A new study shows that organisms can survive being hit by a meteor, ejected into space, and hurtled back to Earth on the face of a rock—which is good news should we ever go the way of the dinosaurs, Astrobiology reports.

Scientists have discovered the remains of the youngest exploding star, or supernova, ever seen in the Milky Way, shedding new light on the life cycles of stars. The baby supernova G1.9+0.3 is a mere 140 years old, reports National Geographic . Supernovas are a vital component of galaxy development because the exploding stars disperse high-energy particles and minerals, fueling the creation of new stars. More »

Britain has released the first batch of secret files on reported UFO sightings, Reuters reports, and concluded that 90% are bogus. The Defense Ministry's Flying Saucer Working Party found that the other unexplained 10% posed no security threat. It has investigated some 11,000 reports dating back to the '50s that include tales of aliens in green overalls and a spaceman named Algar. More »

Stargazers got a new toy today, when Microsoft unveiled WorldWide Telescope, a free new program that gives armchair astronomers an unprecedented look at the stars. The program brings Internet space programs to new heights, rendering complete 3D models of thousands of galactic destinations, the New York Times reports. More »

A hard drive recovered from the Columbia shuttle disaster confirms an old theory about why people shake ketchup before pouring it, LiveScience reports. Astronauts on the craft were conducting a zero-gravity experiment with xenon, a gas, to study viscosity, but scientists feared the results were lost after Columbia burned up 5 years ago. More »

Scientists have found what look like the remains of hot springs on Mars—a sign life could have existed there, reports the Washington Post . Sophisticated equipment returned images of “mounds” that appear remarkably similar to springs found in Australia, according to scientists. They appear to have dried up tens of millions of years ago--fairly recently, in planetary terms. More »

Three space travelers returning from the International Space Station are OK after a rough landing hundreds of miles off course in Kazakhstan this morning, Space.com reports. The Soyuz space capsule carrying US astronaut Peggy Whitson, a Russian cosmonaut, and South Korea's first astronaut veered nearly 300 miles off target and subjected the three to severe G-forces, MSNBC reports.

The New York Yankees' final season at Yankee Stadium will see another first tomorrow night, the Daily News reports, with a US astronaut throwing out the first pitch—via video link from the International Space Station. Garrett Reisman, a 40-year-old New Jersey native and lifelong fan of the Bronx Bombers, will do the honors against the hated Boston Red Sox. More »

The first mammal on Mars may be a monkey. Russia is testing radiation and weightlessness effects on macaques for a possible trip to the red planet. Scientists also want to see how the animals react to isolation and the special diet the 520-day mission would require, reports the BBC. Twelve monkeys have been passengers on previous Soviet and Russian space flights. More »

South Korea’s first astronaut arrived at the International Space Station today, and her country must be relieved—having paid $25 million to get her there, Space.com reports. The South Korean president called So-yeon Yi’s mission a “stepping stone” in that country’s fledgling space program; lacking ships of their own, they paid the Russians to take her on an 11-day spin.

European cargo vessel Jules Verne docked flawlessly today at the International Space Station, Space.com reports. The double-decker-sized space hauler has about 8 tons of supplies on board for astronauts at the station, including food and water, rocket propellant—even handwritten documents from the real Jules Verne, a 19th-century science fiction writer.

Astronomers have spotted the smallest black hole ever discovered, Reuters reports. It is just 15 miles across—the size of a city—but still has a pull strong enough to "stretch your body into a strand of spaghetti," said a NASA researcher. The relative pipsqueak weighs about as much as four suns, while black holes often weigh billions of times more. More »

Basic components of life like heat, organic chemicals, and water have been found on a Saturn moon, Reuters reports. A spacecraft flying over Enceladus this month spotted 500-mile-high geysers spouting off its surface, containing water vapor and the organic molecules found in living things. Though no one’s saying there’s life on Enceladus, later missions will look for liquid water under its surface. More »

The space shuttle Endeavour returned to Earth with a rare night landing to wrap up an ambitious mission to the International Space Station, the AP reports. The shuttle had to land in darkness after NASA called off an earlier attempt because of cloud cover. Astronauts blasted off 16 days ago, delivering a 12-foot robot to the space station and installing the first portion of a Japanese laboratory. More »

NASA has spared its far-flung Mars rovers from budget cuts, reports the Washington Post, after its administrator got wind of the plan to hibernate Spirit and roll Opportunity back to part time. "Closing down either of the rovers is not on the table," his spokesman said, and underlings are looking elsewhere for cuts. More »

The space shuttle Endeavour has begun its two-day trip back to Earth after successfully undocking yesterday from the international space station, reports the Houston Chronicle . The seven astronauts on board hailed an "awesome" mission and said fond farewells to their colleagues staying behind. A glitch unlatching a solar panel delayed Endeavour's retreat from the station.

NASA confirmed and denied plans today to scuttle a Mars rover and fire 300 employees, CNN reports. The space agency first announced a $4 million cut to the Mars program's $20 million budget and vowed to unplug one of two rovers roaming the red planet. Then a NASA spokesman told CNN that "the cancellation of the Mars Exploration Rovers is not under consideration." More »

Humans took centuries to discover the other planets in the solar system, but in the 13 years since the first additional planet was identified, planetary scientists have found 277 more worlds orbiting other suns. And those extrasolar planets are just the confirmed ones—many more are suspected, and excitement among scientists is building, reports the Washington Post. More »

The crew of shuttle Endeavour prepared to undock from the International Space Station today after a leisurely Easter Sunday spent off-loading cargo, enjoying a holiday meal, and talking to family back home. The shuttle commander compared the flurry of work to wrap up the record-setting mission to March Madness: "It's wonderful to be in the tournament. We've won five games," said Dom Gorie, referring to the crew's five spacewalks. More »
