“It was built in 170 AD.”

Deutsche Welle: Largest Roman city gate north of the Alps finally dated. “Archaeologists have determined the exact date of construction of the Porta Nigra in Trier — it was built 1,848 years ago. It’s the oldest monument of its kind in Germany.”

Deutsche Welle: Trierer Porta Nigra ist exakt 1848 Jahre alt. “Nicht nur der Schmutz der Jahrhunderte hat das Stadttor Porta Nigra in Trier tiefschwarz werden lassen. Jetzt wurde anhand von Holzfunden das wahre Alter des von den Römern errichteten Monuments festgestellt.”

“So aufgeräumt und so sauber, wie man es sich immer vorstellt, ist es nicht.”

Deutsche Welle: Plastikpiraten: Tausende Schüler erforschen Müll an deutschen Flüssen. “Über 5500 Jugendliche haben Müll in Flüssen gesammelt und gezählt – und ihre Daten mit Wissenschaftlern ausgewertet. Die Ergebnisse sind erschreckend, sagt Lehrerin und Wissenschaftlerin Katrin Kruse.”

“Uns wird immer mehr klar, dass auch in Deutschland jede Menge Müll in die Meere gelangt. Für die Schüler sind es aber doch noch neue Kenntnisse. Sie denken, dass das bei uns in Deutschland kein Problem sei. Hier werden Straßen, Ufer und Strände regelmäßig gereinigt. Doch die Untersuchungsergebnisse haben ein anderes Bild gezeichnet. Für die Schüler ist es dann doch sehr erschreckend, wenn man mal genau hin guckt, was eigentlich so am Flussufer rum liegt. Auch dass so viel Plastik unter dem Müll war, ist für die Schüler einigermaßen überraschend gewesen. Ich glaube, dass die Untersuchung für die beteiligten Schüler sehr, sehr nachhaltig ist.”

“President Trump on Monday drastically scaled back two national monuments established in Utah by his Democratic predecessors”

Tuesday, December 5th, 2017

The Washington Post: Trump shrinks two huge national monuments in Utah, drawing praise and protests.

“Trump’s move to shrink the Bears Ears and Grand Staircase-Escalante national monuments by more than 1.1 million acres and more than 800,000 acres, respectively, immediately sparked an outpouring of praise from conservative lawmakers as well as activists’ protests outside the White House and in Utah. It also plunges the Trump administration into uncharted legal territory since no president has sought to modify monuments established under the 1906 Antiquities Act in more than half a century.

His decision removes about 85 percent of the designation of Bears Ears and nearly 46 percent of that for Grand Staircase-Escalante, land that potentially could now be leased for energy exploration or opened for specific activities such as motorized vehicle use.

Trump told a rally in Salt Lake City that he came to “reverse federal overreach” and took dramatic action “because some people think that the natural resources of Utah should be controlled by a small handful of very distant bureaucrats located in Washington. And guess what? They’re wrong.”

“They don’t know your land, and truly, they don’t care for your land like you do,” he added. “But from now on, that won’t matter.””

Read Garret’s opinion on the matter over at dangerousmeta: Ignore the Administration. Ignore the media.

“At 13 billion miles from Earth, there’s no mechanic shop nearby to get a tune-up.”

JPL CalTech: Voyager 1 Fires Up Thrusters After 37 Years

Voyager 1, NASA’s farthest and fastest spacecraft, is the only human-made object in interstellar space, the environment between the stars. The spacecraft, which has been flying for 40 years, relies on small devices called thrusters to orient itself so it can communicate with Earth. These thrusters fire in tiny pulses, or “puffs,” lasting mere milliseconds, to subtly rotate the spacecraft so that its antenna points at our planet. Now, the Voyager team is able to use a set of four backup thrusters, dormant since 1980.

“With these thrusters that are still functional after 37 years without use, we will be able to extend the life of the Voyager 1 spacecraft by two to three years,” said Suzanne Dodd, project manager for Voyager at NASA’s Jet Propulsion Laboratory, Pasadena, California.”
