Sten Odenwald – författare

On March 13, 1989, the entire Quebec power grid collapsed, automatic garage doors in California suburbs began to open and close without apparent reason, and microchip production came to a halt in the Northeast; in space, communications satellites had to be manually repointed after flipping upside down, and pressure readings on hydrogen tank supplies on board the Space Shuttle Discovery peaked, causing NASA to consider aborting the mission. What was the cause of all these seemingly disparate events? Sten Odenwald gives convincing evidence of the mischievous-and potentially catastrophic-power of solar storms and the far-reaching effects of the coming "big one" brewing in the sun and estimated to culminate in the twenty-third cycle in the year 2001 and beyond. When the sun undergoes its cyclic "solar maximum," a time when fierce solar flares and storms erupt, fantastic auroras will be seen around the world. But the breathtaking spectacles will herald a potentially disastrous chain of events that merit greater preparation than Y2K. Is anyone listening?The 23rd Cycle traces the previously untold history of solar storms and the ways in which they were perceived by astronomers-and even occasionally covered up by satellite companies. Punctuated with an insert containing dramatic color images showing the erupting sun, the book also includes a history of the record of auroral sightings, accounts of communications blackouts from the twentieth century, a list of industries sensitive to solar storms, and information about radiation and health issues.

Within the pages of this eclectic pop-history, scientist and educator Sten Odenwald at NASA examines 100 objects that forever altered what we know and how we think about the cosmos. From Sputnik to Skylab and Galileo’s telescope to the Curiosity rover, some objects are iconic and some obscure—but all are utterly important.The Nebra sky disk (1600 BCE) features the first realistic depiction of the Sun, Moon, and stars.The Lunar Laser Ranging RetroReflector finally showed us how far we are from the Moon in 1969.In 1986, it was the humble, rubber O-ring that doomed the space shuttle Challenger.The Event Horizon Telescope gave us our first glimpse of a black hole in 2019.These 100 objects, as Odenwald puts it, showcase “the workhorse tools and game-changing technologies that have altered the course of space history . . . the tools and devices that, taken together, represent the major scientific discoveries—and celebrate the human ingenuity—of space technology, showing the ways physics and engineering have brought about our greatest leaps in understanding the way our universe works. . . . They make it clear that we have made giant strides in our quest to search ever more deeply into the farthest reaches of the universe—and behind each new discovery is an object that expands our appreciation of space as well as the boundless imagination and resourcefulness we carry within us.”
