Scientists will attempt to be the first to drill into Earth’s mantle

Scientists want to plumb the Earth for one of its last secrets. An international group of researchers led by  Japan’s Agency for Marine-Earth Science and Technology say they plan to be the first to successfully drill into the mantle, that is, the region sandwiched between the planet’s outer crust and its inner core. Although the mantel makes up about 80 percent of the Earth’s mass, much of it remains a geological enigma. “We don’t know the exact [composition] of the mantle yet,” researcher Natsue Abe told CNN . To access the mantel, JAMSTEC will deploy the Chikyu, one of its biggest and most sophisticated drilling vessels, to penetrate 2.5 miles of ocean, then another 3.7 miles of sea floor (a.k.a the crust). The Japanese government is backing the expedition in the hopes that the data gleaned will help scientists better predict earthquakes.

So we need to know the natural system more clearly or precisely … we have to observe the Earth more precisely.” All three drilling sites currently under consideration are located in the Pacific Ocean. The first is off Hawaii, the second off Costa Rica, and the third is off Mexico. “We already drilled and have taken some samples from the ocean floor but [only] from the top,” Abe said. “[We want] to dig from the ocean floor to the deep pristine mantle.” Via CNN Earth image via Wikimedia  and Flickr

Why scientists will march in over 400 cities on Earth Day

Even if the president of the United States rejects science , scientists plan to make their voices heard. Tomorrow they’ll march on Washington, D.C. and over 400 locations around the world in the March for Science . While organizers say the march was inspired by the success of the January 21 Women’s March, they also emphasize their event is nonpartisan. Their march will celebrate science and highlight “the need to respect and encourage research that gives us insight into the world.” Tens of thousands of people are expected to show up for the March for Science in Washington, D.C. tomorrow. People will gather at the Washington Monument starting at 8:00 AM, and will participate in teach-ins and a rally program until the march at 2:00 PM. Speakers include Bill Nye and pediatrician Mona Hanna-Attisha who helped expose Flint , Michigan lead poisoning.

Scientists and academics have been concerned for years now over public distrust of science. The event’s mission page says, “People who value science have remained silent for far too long in the face of policies that ignore scientific evidence and endanger both human life and the future of our world. New policies threaten to further restrict scientists’ ability to research and communicate their findings. We face a possible future where people not only ignore scientific evidence, but seek to eliminate it entirely…We must take science out of the labs and journals and share it with the world.” The American Association for the Advancement of Science , the American Chemical Society , and the American Geophysical Union all support the march. Satellite marches will take place on six different continents. You can register for the march in Washington, D.C. or find a march near you here . If you can’t attend the Earth Day science march, you can march for climate science in the People’s Climate Mobilization on DC on April 29. + March for Science Via The Washington Post Images via Wikimedia Commons and March for Science
