Full Braking at Alpha Centauri Gottingen, Germany (SPX) Feb 03, 2017 In April last year, billionaire Yuri Milner announced the Breakthrough Starshot Initiative. He plans to invest 100 million US dollars in the development of an ultra-light light sail that can be accelerated to 20 percent of the speed of light to reach the Alpha Centauri star system within 20 years. The problem of how to slow down this projectile once it reaches its target remains a challenge. Rene Heller of the Max Planck Institute for Solar System Research in Gottingen and his colleague Michael Hi ... read more |

Indian Space Research Organisation (ISRO) successfully ground tested its indigenously developed Cryogenic Upper Stage for GSLV MkIII on January 25, 2017. The cryogenic stage designated as C25 was tested for a duration of 50 seconds at ISRO Propulsion Complex (IPRC) in Mahendragiri demonstrating all the stage operations. The performance of the Stage during the test was as predicted. This is the f ... more |

Mars may be home to some of the oldest volcanoes in the solar system. New evidence suggests the Red Planet has been home to volcanic activity for at least 2 billion years. The evidence is a small Martian meteorite discovered in Africa in 2012. The rock was named Northwest Africa 7635. Scientists has studied many Martian meteorites over the years. Most arrived on Earth's surface r ... more |
China's plans for deep-space exploration included two Mars missions and one Jupiter probe. China plans its first Mars probe by 2020, said Wu Yanhua, vice director of the China National Space Administration. A second Mars probe will bring back samples and conduct research on the planet's structure, composition and environment, Wu said. Also on the agenda are an asteroid explorat ... more |
Iridium Communications has contracted with SpaceX for an eighth Falcon 9 launch. Along for the ride are the twin-satellites of the NASA/GFZ Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission, which will be deployed into a separate low-Earth orbit, marking the first rideshare deal for Iridium. An agreement of this kind is economical for all parties, and affords Iridium the abili ... more |
Japan's ancient art of paper folding has inspired the design of a potentially trailblazing "smart" radiator that a NASA technologist is now developing to remove or retain heat on small satellites. Vivek Dwivedi, a technologist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, has teamed with a couple of researchers at Brigham Young University in Utah to advance an unconventiona ... more |

A new device on the W.M. Keck Observatory in Hawaii has delivered its first images, showing a ring of planet-forming dust around a star, and separately, a cool, star-like body, called a brown dwarf, lying near its companion star. The device, called a vortex coronagraph, was recently installed inside NIRC2 (Near Infrared Camera 2), the workhorse infrared imaging camera at Keck. It has the potenti ... more |
Where should NASA's Juno spacecraft aim its camera during its next close pass of Jupiter on Feb. 2? You can now play a part in the decision. For the first time, members of the public can vote to participate in selecting all pictures to be taken of Jupiter during a Juno flyby. Voting begins Thursday, Jan. 19 at 11 a.m. PST (2 p.m. EST) and concludes on Jan. 23 at 9 a.m. PST (noon EST). "We ... more |

Oceanographers commonly calculate large scale surface ocean circulation from satellite sea level information using a concept called "geostrophy", which describes the relationship between oceanic surface flows and sea level gradient. Conversely, researchers rely on data from in-water current meters to measure smaller scale motion. New research led by University of Hawai'i at Manoa (UHM) oce ... more |
Indian Regional Navigation Satellite System (IRNSS) was launched as a more accurate navigation system compared to the US' GPS system. However, some as yet unexplained technical failures have put the accuracy of the system into question. The Indian Space Research Organization (ISRO) has downplayed the failure of three atomic clocks onboard one of the satellites of the India's home grown amb ... more |

Moon Express, the first private company to receive government approval for a space mission, has announced an additional $20 million raised for a lunar voyage in late 2017. A front-runner to win Google's Lunar XPrize, the $20-million grant for the first "privately funded team" to "successfully place a spacecraft on the moon's surface," "travel 500 meters,"and "transmit high-definition video ... more |
A recently discovered solitary ice volcano on the dwarf planet Ceres may have some hidden older siblings, say scientists who have tested a likely way such mountains of icy rock - called cryovolcanoes - might disappear over millions of years. NASA's Dawn spacecraft discovered Ceres's 4-kilometer (2.5-mile) tall Ahuna Mons cryovolcano in 2015. Other icy worlds in our solar system, like Pluto ... more |

Researchers in Japan say they may be one step closer to solving the mystery at the core of the Earth. It has long been established that approximately 85 percent of the Earth's core is made of iron, while nickel makes up an additional 10 percent. Details of the final 5 percent - believed to be some amount of light elements - has, until now, eluded scientists. According to the Japanese ... more |
A long-standing mystery among marine biologists is why otherwise healthy whales, dolphins, and porpoises - collectively known as cetaceans - end up getting stranded along coastal areas worldwide. Could severe solar storms, which affect Earth's magnetic fields, be confusing their internal compasses and causing them to lose their way? Although some have postulated this and other theories, no ... more |

An international science team says NASA's Fermi Gamma-ray Space Telescope has observed high-energy light from solar eruptions located on the far side of the sun, which should block direct light from these events. This apparent paradox is providing solar scientists with a unique tool for exploring how charged particles are accelerated to nearly the speed of light and move across the sun during so ... more |
Researchers from Ludwig-Maximilians-Universitaet (LMU) Munich have, for the first time, measured the lifetime of an excited state in the nucleus of an unstable element. This is a major step toward a nuclear clock that could keep even better time than today's best atomic timekeepers. Atomic clocks are the most precise chronometers we now have. These timekeepers are based on precise knowledg ... more |
