  Laurel MD (SPX) Dec 28, 2018 The New Horizons spacecraft is healthy and on final approach to the first close-up exploration of a Kuiper Belt object in history, and the farthest exploration of any world, ever. In just a few days, on New Year's Eve and New Year's Day, New Horizons will swoop three times closer to our target-2014 MU69 (nicknamed Ultima Thule)-than we flew past Pluto. The anticipation is palpable now: we are on the verge of an important scientific exploration almost 20 years in the making and, in many ways, unlik ... read more |

 Pasadena CA (JPL) Dec 24, 2018 
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 |

 Edmonton, Canada (SPX) Dec 21, 2018 
New research from University of Alberta physicists provides the first-ever model of our Moon's rotational dynamics, taking into consideration its solid inner core. Their model helps to explain why, as seen from Earth, the Moon appears to wobble on its axis.
The answer, said physicist Mathieu Dumberry, lies in the complex geometry of the Moon's orbit, locked in what is known as a Cassini st ... 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 |

 Greenbelt MD (SPX) Dec 18, 2018 
New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 and 2 observations made decades ago. The rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturn's magnetic field.
"We estimate that this 'ring rain' drains an amount of water products that could fill an Olympic-sized swimming p ... 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 |
