In the 1960s, humans took their first steps away from Earth, and for a time our possibilities in space seemed endless. But in a time of austerity and in the wake of high-profile disasters like Challenger, that dream seems to have ended. In early 2011, Margaret Lazarus Dean traveled to Cape Canaveral for NASA's last three space shuttle launches in order to bear witness to the end of an era. In her new book "Leaving Orbit: Notes from the Last Days of American Spaceflight" Dean serves as our guide to Florida's Space Coast and to the history of NASA.

Community farms. Mud spas. Mineral paints. Nematodes. Barbara Richardson, editor of the anthology, “Dirt: A Love Story” says the world is waking up to the beauty and mystery of dirt. The anthology brings together essays by scientists, authors, artists, and dirt lovers --admiring the first worm of spring, taking a childhood twirl across a dusty Kansas farm, calculating how soil breathes, or baking mud pies. Essayists build a dirt house, center a marriage around dirt, sink down into marshy heaven, and learn to read dirt's own language. Whether taking a trek to Venezuela to touch the oldest dirt in the world or reveling in the blessings of our own native soils, these essays answer the important question: How do you get down with dirt?

Justin Hocking, author of the memoir, “The Great Floodgates of the Wonderworld,” writes: “Fifteen years ago, I first dove into the immense, dark waters of Melville's masterpiece...I became obsessed with a book about obsession. More so when I discovered some critical work that compared Moby-Dick's narrative trajectory with Carl Jung's concept of the night sea journey—the dark passages that we all embark on, where we find ourselves floating and directionless, frightened and alone. At age thirty, I relocated to New York City. With no job prospects, it was both the boldest and the most senseless move of my life…in the wake of a painful break-up and a traumatic robbery, I soon found myself on my own night sea journey. It was a time during which, to paraphrase Joan Didion, I lost my own life's narrative. Without my own script, I clung to Moby-Dick as a kind of postmodern survival guide.” “Wonderworld,” published by Graywolf Press, also takes us into the worlds of skateboarding and New York surfing culture, and Wednesday night meetings of men striving to overcome addictions.

In 2015 the number of visitors to Yellowstone exceeded four million for the first time. David Quammen, writing in the May 2016 edition of National Geographic magazine, asks "Can we hope to preserve, in the midst of modern America, any such remnant of our continent's primordial landscape, any such sample of true wildness-a gloriously inhospitable place, full of predators and prey, in which nature is still allowed to be red in tooth and claw? Can that sort of place be reconciled with human demands and human convenience? Time alone, and our choices, will tell. But if the answer is yes, the answer is Yellowstone."

Consider the $20 bill.
