  Kazan, Russia (SPX) Dec 27, 2018 Meteor burst communication is based on using meteors as cryptography assistants. Meteor trails reflect radio waves, which makes them suitable for radio transmissions at distances of up to 2,000 kilometers. Unpredictable nature of meteors makes pose a significant hindrance for signal interception. Associate Professor Amir Sulimov explains, "Each meteor trail forms a kind of a shadow resembling an ellipse on the Earth's surface. All communication stations within that area can tune in on the channel. ... read more |

 Laurel MD (SPX) Dec 27, 2018 
NASA's New Horizons spacecraft is set to fly by a distant "worldlet" 4 billion miles from the Sun in just six days, on New Year's Day 2019. The target, officially designated 2014 MU69, was nicknamed "Ultima Thule," a Latin phrase meaning "a place beyond the known world," after a public call for name recommendations. No spacecraft has ever explored such a distant world.
Ultima, as the flyby ... more |

Mars atmospheric opacity (tau) over the rover site remains at a storm-free range around 1.0.
No signal from Opportunity has been heard since Sol 5111 (June 10, 2018). Opportunity likely experienced a low-power fault, a mission clock fault and an up-loss timer fault.
Since the loss of signal, the team has been listening for the rover over a broad range of times, frequencies and polari ... more |

 Stanford CA (SPX) Dec 27, 2018 
When hydropower runs low in a drought, western states tend to ramp up power generation - and emissions - from fossil fuels. According to a new study from Stanford University, droughts caused about 10 percent of the average annual carbon dioxide emissions from power generation in California, Idaho, Oregon and Washington between 2001 and 2015.
"Water is used in electricity generation, both d ... more |

 Hannover, Germany (SPX) Dec 17, 2018 
The detection of Einstein's gravitational waves relies on highly precise laser measurements of small length changes. The kilometer-size detectors of the international network (GEO600, LIGO, Virgo) are so sensitive that they are fundamentally limited by tiny quantum mechanical effects.
These cause a background noise which overlaps with gravitational-wave signals. This noise is always presen ... more |
