NASA's OSIRIS-REx Begins Earth-Trojan Asteroid Search Greenbelt MD (SPX) Feb 14, 2017 A NASA spacecraft begins its search Thursday for an enigmatic class of near-Earth objects known as Earth-Trojan asteroids. OSIRIS-REx, currently on a two-year outbound journey to the asteroid Bennu, will spend almost two weeks searching for evidence of these small bodies. Trojan asteroids are trapped in stable gravity wells, called Lagrange points, which precede or follow a planet. OSIRIS-REx is currently traveling through Earth's fourth Lagrange point, which is located 60 degrees ahead in Earth's ... read more |

NASA may have to book seats for American astronauts on Russian Soyuz spaceships in 2018. Radio Sputnik discussed the issue with John Logsdon, Professor Emeritus of Political Science and International Affairs at George Washington University. "The relationship between NASA and the former Soviet Union goes back a long way with the highlight being the 1975 Apollo-Soyuz project. But with Russia ... more |
Private space travel company SpaceX lifted it's Falcon 9 rocket at Florida's Kennedy Space Center to undergo testing in preparation for a potential launch. SpaceX CEO Elon Musk, shared a photo of the rocket in its upright position at the launchpad in Cape Canaveral where the first manned mission to the moon was launched. "Falcon 9 rocket now vertical at Cape Canaveral on launch c ... more |

Scientists from Indian Space Research Organization (ISRO) have successfully executed crucial orbital maneuvering on Mars spacecraft to give it another lease of life. The Mission was facing imminent death as it was to face an eclipse during which dark shadows of Mars would block light to spacecraft's solar panel. After hours long remotely controlled execution which activated onboard t ... 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 |
Any nation that hopes to have a space program needs to be able to keep an eye on its orbiting assets at all times. This means that Australia has become a key link in the global chain of ground-based tracking stations. The US National Aeronautics and Space Administration (NASA) has a deep space tracking facility at Tidbinbilla in the ACT, managed by the CSIRO, and the European Space Agency (ESA) ... more |
Astronomers at Lomonosov Moscow State University in cooperation with their French colleagues and with the help of citizen scientists have released "The Reference Catalog of galaxy SEDs" (RCSED), which contains value-added information about 800,000 galaxies. The catalog is accessible on the web and its description has been published in the Astrophysical Journal Supplement (impact factor - 11.257) ... more |

The search for life beyond Earth starts in habitable zones, the regions around stars where conditions could potentially allow liquid water - which is essential for life as we know it - to pool on a planet's surface. New NASA research suggests some of these zones might not actually be able to support life due to frequent stellar eruptions - which spew huge amounts of stellar material and radiatio ... more |
A report on the potential science value of a lander on the surface of Jupiter's icy moon Europa has been delivered to NASA, and the agency is now engaging the broader science community to open a discussion about its findings. In early 2016, in response to a congressional directive, NASA's Planetary Science Division began a pre-Phase A study to assess the science value and engineering desig ... more |

The Louisiana coastline is sinking under the Gulf of Mexico at the rate of about one football field of land every hour (about 18 square miles of land lost in a year). But within this sinking region, two river deltas are growing. The Atchafalaya River and its diversion channel, Wax Lake Outlet, are gaining about one football field of new land every 11 and 8 hours, respectively (1.5 and 2 square m ... more |
Global Navigation Satellite System (GNSS) signals are critical tools for industries requiring exact precision and high confidence. Now, Geoscience Australia, an agency of the Commonwealth of Australia, and Lockheed Martin have entered into a collaborative research project to show how augmenting signals from multiple GNSS constellations can enhance positioning, navigation, and timing for a range ... more |

The Moon may be peppered with oxygen transmitted by life on Earth, according to a scientific study, opening up the possibility that the Earth's atmosphere of billions of years ago may be preserved on the present-day lunar surface. It has long been speculated that the Moon has been intermittently sprayed with the Earth's oxygen, with some researchers suggesting the nitrogen and noble gases ... more |
Radar images of asteroid 2017 BQ6 were obtained on Feb. 6 and 7 with NASA's 70-meter (230-foot) antenna at the Goldstone Deep Space Communications Complex in California. They reveal an irregular, angular-appearing asteroid about 660 feet (200 meters) in size that rotates about once every three hours. The images have resolutions as fine as 12 feet (3.75 meters) per pixel. "The radar images ... more |

Igor Kolokolov and Vladimir Lebedev, scientific experts from HSE's Faculty of Physics and the Landau Institute for Theoretical Physics of Russian Academy of Sciences, have developed an analytical theory, which binds the structure of coherent vortices formed due to inverse cascades in 2-D turbulence with the statistical properties of hydrodynamic fluctuations. Uncovering this link can be us ... more |
An international team led by researchers at Nagoya University, along with US and Swiss colleagues, has identified a new type of solar event and dated it to the year 5480 BC; they did this by measuring carbon-14 levels in tree rings, which reflect the effects of cosmic radiation on the atmosphere at the time. They have also proposed causes of this event, thereby extending knowledge of how the sun ... more |

Astronomers at The University of Texas at Austin have developed a new technique to discover the faintest galaxies yet seen in the early universe -10 times fainter than any previously seen. These galaxies will help astronomers probe a little-understood, but important period in cosmic history. Their new technique helps probe the time a billion years after the Big Bang, when the early, dark univers ... more |
All known black holes fall into two categories: small, stellar-mass black holes weighing a few Suns, and supermassive black holes weighing millions or billions of Suns. Astronomers expect that intermediate-mass black holes weighing 100 - 10,000 Suns also exist, but so far no conclusive proof of such middleweights has been found. Today, astronomers are announcing new evidence that an intermediate ... more |
