Is Progress Outpacing Precaution? Experts Weigh In

Illustration by An Arres.

No one expects the machinery of progress to roll backwards, but sometimes it seems that no one is watching the speedometer (or manning the brakes, assuming any exist).  Is this a fair assessment? If so, should we be worried — and what can we do about it?

In this feature, experts on technology, risk, science, policy and neuroscience discuss risk, innovation and how our values affect our conceptions of both.

Spotting Fracking and Pumping Effects from Space

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.

Who Names NASA’s Space Probes?

The latest NASA space probes to make the news have zoomed to the farthest reaches of the solar system, and their names – Pluto’s New Horizons, comet 67P/Churyumov-Gerasimenko’s Rosetta and Philae – reflect the ambition and spirit of discovery behind them.

But who gets to pick those evocative names, and is there any pattern that ties them together? Read on …

The James Webb Space Telescope Prepares to Peer Past Hubble

For two decades, the Earth-orbiting Hubble Space Telescope helped pierce the veil of time, image stellar nurseries and prove that galaxies collide. Now, the James Webb Space Telescope stands poised to take those observations to the next level, making the delicate observations possible only in the cold, dark spaces beyond the moon.

Slated for a 2018 launch date and team-built by 14 countries, 27 states and the District of Columbia, Webb will take astronomers closer to the beginning of time than ever before, granting glimpses of sights long hypothesized but never seen, from the birth of galaxies to light from the very first stars. Join us as we explore…
