U.S.-Russian crew lands in Kazakhstan after 172 days in space
A U.S. astronaut and two Russian cosmonauts wrapped up a 172-day mission aboard the International Space Station with a parachute descent and landing at dawn on the steppes of Kazakhstan, a NASA TV broadcast showed. The capsule made a parachute descent southeast of Zhezkazgan, disappearing into a layer of haze as it neared the ground.
Spacecom CEO wants 'several safe flights' before using SpaceX again
The chief executive of Israeli satellite operator Space Communication Ltd said on Tuesday he wants to see "several safe flights" from SpaceX before using Elon Musk's space firm again to launch one of his company's satellites. In an interview with Reuters, Spacecom CEO David Pollack also said he does not know what caused the explosion last Thursday that destroyed a SpaceX Falcon 9 rocket along with his company's $200 million AMOS-6 communications satellite.
Some like it hot: scientists drill off Japan for sizzling life
Scientists will start drilling off Japan this month to seek the hottest place where life can survive in a hellish uncharted realm deep below the seabed. The drilling under the Nankai Trough in the Pacific Ocean will be part of a project by 900 experts to map carbon underground, hoping for clues to everything from the origin of life on Earth to the formation of oil and gas.
NASA asteroid probe may find clues to origins of life on Earth
A U.S. space probe was cleared for launch on Thursday to collect and return samples from an asteroid in hopes of learning more about the origins of life on Earth and perhaps elsewhere in the solar system, NASA said on Tuesday. A United Launch Alliance Atlas 5 rocket was scheduled to blast off from Cape Canaveral Air Force Station in Florida to dispatch the robot explorer Osiris-Rex on a seven-year mission.
Scientists find deadly scrub typhus bacteria in South America
Scrub typhus, a deadly disease common in southeast Asia and spread by microscopic biting mites known as chiggers, has now taken hold in a part of South America and may have become endemic there, scientists said on Wednesday. The tropical disease, which kills at least 140,000 people a year in the Asia-Pacific region, has been confirmed in a cluster of cases on a large island off Chile, some 12,000 kilometers from its usual haunts on the other side of the Pacific.
Tiny 'fitbits' to keep tabs on the body from within
Scientists are developing dust-sized wireless sensors implanted inside the body to track neural activity in real-time, offering a potential new way to monitor or treat a range of conditions including epilepsy and control next-generation prosthetics. The tiny devices have been demonstrated successfully in rats, and could be tested in people within two years, the researchers said.
