Spotting Fracking and Pumping Effects from Space

2011-2014 Hydraulic Fracturing Water Use (square meters/well)

Using a technique called satellite radar interferometry, researchers have spotted millimeter-scale ground uplift surrounding four high-pressure injection wells near the eastern Texas city of Timpson. Two of the wells were located directly above a spate of record quakes that struck Timpson in 2012, topping out with a 4.8 magnitude quake on May 17. The other two were located within six miles of the quakes.

NASA’s recent news that the Hubble Space Telescope had spotted liquid water plumes on Jupiter’s moon Europa has raised interest in a planned mission that will study the icy world to confirm the ocean’s presence and search for signs of life.

An instrument being built by Arizona State University will show experts where to start looking.

An Arizona State University program this semester will use veterans to archive digital archaeological data from the U.S. Army Corps of Engineers.

The four veterans will train and work at ASU’s Center for Digital Antiquity, which houses the nation’s largest archive of digital archaeological data.

A 200-mile lightning flash and another flash lasting nearly eight seconds have redefined experts’ notions of what is possible for such events.

The new data prompted a World Meteorological Organization committee to recommend revising the definition of lightning discharges.
