What Mars Maps Got Right (and Wrong) Through Time
Tracing the history of Mars maps is like taking a visual tour of how our thinking about the red planet has changed. Each new telescope and space mission brought about a leap in understanding that is reflected in the maps that followed. These days our knowledge about Earth's second closest neighbor in the solar system grows by the hour, as the Curiosity and Opportunity rovers explore the Martian surface with five active satellites orbiting above them. And on October 19, the fleet grew by at le..>> view originalAccidental discovery could be renewable energy breakthrough
In an unexpected twist of fate, scientists at the Department of Energy’s Oak Ridge National Laboratory have developed a process to turn carbon dioxide, a greenhouse gas, into ethanol fuel — a breakthrough with implications for the future of renewable energy.That discovery, which occurred in 2014 and has been replicated multiple times since then in the nanotechnology lab Oak Ridge, Tennessee, is explained in full in a new study published in ChemistrySelect.The finding was serendipitous, lead stu..>> view original2 quake faults in the Bay Area could rupture together, causing major devastation, scientists say
The most dangerous earthquake fault in the San Francisco Bay Area is connected to another, which means both could rupture simultaneously and unleash major devastation, a new study finds.The Hayward Fault has long been considered a threat because it runs under densely populated neighborhoods east of San Francisco. The new study found that beneath San Pablo Bay, it joins with a second, less active underground fracture to the north. Scientists had already considered the possibility of both faults..>> view originalThose Ancient Stone Tools — Did Humans Make Them, Or Was It Really Monkeys?

Lately I’ve been thinking back to something that John Kerry told The Atlantic’s editor in chief, Jeffrey Goldberg, earlier this year. Asked about the importance of the Middle East to the United States, Kerry answered entirely about the Islamic State.“Imagine what would happen if we don’t stand and fight [ISIS],” he said: If we didn’t do that, you could have allies and friends of ours fall. You could have a massive migration into Europe that destroys Europe, leads to the pure destruction of Euro..>> view original[ October 19, 2016 ] ESA celebrates ExoMars orbiter success, keeps vigil for lost lander News

Both spacecraft — part of the joint European-Russian ExoMars program — reached Mars around the same time Wednes..>> view originalNASA's Juno Probe Sidelined Just Before Jupiter Flyby
NASA's Juno spacecraft has encountered its second problem at Jupiter in less than a week. The probe went into a protective "safe mode" at 1:47 a.m. EDT (0547 GMT) this morning (Oct. 19), preventing the spacecraft from gathering any data during today's ...>> view original
