In August, a rover named Curiosity touched down inside Mars’ Gale Crater, carrying 10 new instruments that will advance the quest for signs that Mars might once have been suitable for life. But Curiosity’s mission is risky. After parachuting through the Martian atmosphere at twice the speed of sound, Curiosity was gently lowered to the planet’s surface by a “sky crane.” This first-of-its-kind system has been tested on Earth, but there was no guarantee it would work on Mars.
Between the blue sky above us and the infinite blackness of space lies a frontier full of enigmas that scientists have only just begun to investigate. “At the Edge of Space” takes viewers on a spectacular exploration to probe the earth-space boundary zone, home to some of nature’s most puzzling and alluring phenomena: the shimmering aurora, streaking meteors, and fleeting flashes that shoot upwards from thunderclouds, known as sprites.
Fifty years later, what can science tell us about the Kennedy assassination — and the investigations that followed? The 1963 murder, in broad daylight in front of hundreds of witnesses, was a homicide investigator’s best-case scenario. Yet somehow the JFK assassination became a forensic nightmare, plagued by mishandled evidence, a controversial autopsy and, incredibly, a prime suspect murdered while in police custody before he could be tried — all of it captured on film.
Is it possible to engineer an absolutely safe world for ourselves? Host David Pogue explores the extent to which science and technology can protect us from monumental forces of nature such as earthquakes and epidemics. He challenges researchers to save us from dangers of our own making, such as traffic accidents and contact sports.
