Sentinels From Space

During much of the Cold War, America's first line of defense was in outer space: a network of secret satellites that could provide instant warning of an enemy missile launch. The presence of these infrared sensors orbiting 22,000 miles above the earth discouraged a Soviet first strike and stabilized international relations between the superpowers, and they now play a crucial role in monitoring the missile programs of China, India, and other emerging nuclear powers. Jeffrey Richelson has written the first comprehensive history of this vital program, tracing its evolution from the late 1950s to the present. He puts Defense Support Program operations in the context of world events - from Russian missile programs to the Gulf War - and explains how DSP's infrared sensors are used to detect meteorites, monitor forest fires, and even gather industrial intelligence by "seeing" the lights of steel mills.

2019 PRISM Award Winner! “The answer is no, Lyra,” my mother utters her favorite—I swear—phrase. No means I have to travel with them to another planet—again. No means leaving all my friends fifty years in the past. Thanks, Einstein. Seventeen-year-old Lyra Daniels can’t truly blame Einstein or her parents for their impending move across the Milky Way Galaxy. It’s all due to the invention of the Q-net, which made traveling the vast distances in space possible—with one big caveat: the time dilation. But that never stopped Lyra's ancestors from exploring the Milky Way, searching for resources and exoplanets to colonize. What they didn’t expect to find is life-sized terracotta Warriors buried on twenty-one different exoplanets. ... Make that twenty-two. As the Galaxy’s leading experts on the Warriors, Lyra's parents are thrilled by the new discovery, sending them—and her—fifty years into the future. Her social life in ruins, she fills her lonely days by illegally worming into the Q-net. The only person close to her age is the annoyingly irresistible security officer who threatens to throw her into the brig. After the planet they just left goes silent—meaning no communications from them at all—security has bigger problems to deal with than Lyra, especially when vital data files go missing. But that's just the beginning, because they’re not as alone as they thought on their new planet... and suddenly time isn't the only thing working against them.

Year 2522. Oh. My. Stars. Junior Officer Ara Lawrence here, reporting for duty. Again. It's situation critical for the security team and everyone in the base - including my parents - with a new attack from the looters imminent, a possible galaxy-wide crime conspiracy and an unstoppable alien threat. But this all pales in the face of my mind-blowing discovery about the Q-net. Of course, no one believes me. I'm not sure I believe me. It could just be a stress-induced delusion. That's what my parents seem to believe... Their concern for me is hampering my ability to do my job. I know they love me, but with the Q-net in my corner, I'm the only one who can help the security team beat the shadowy aliens from the pits we discovered. We're holding them at bay, for now, but the entire Milky Way Galaxy is in danger of being overrun. With battles on too many fronts, it's looking dire. But one thing I've learned is when people I love are in jeopardy, I'll never give up trying to save them. Not until my dying breath. Which could very well be today...

There is a growing concern over the ubiquitous distribution of plastic pollution that is evolving in the Beaufort Gyre in the Arctic Ocean, prompting international collaboration and new environmental measures. Marine pollution is recognised as an immediate threat to both land and marine ecosystems. Satellites have proven useful in identifying ocean plastic patches and current movements in other oceans but little research has been applied to the Arctic, a region that impacts eight countries making up the Arctic Circle. This interdisciplinary team project investigates the use of Sentinel-2, Sentinel-6, Fourier-Transform Spectroscopy, stratospheric balloons and autonomous underwater vehicles to provide an integrated strategy, including communication and outreach, to tackling marine plastic pollution while recognizing that it is necessary to also prevent plastics from entering the ocean in the first place.
