Defying Limits: Lessons from the Edge of the Universe

The international prestige of winning the Moon Race cannot be understated, and Grissom played a pivotal and enduring role in securing that legacy for the United States. Indeed, Grissom was first and foremost a Cold Warrior, a member of the first group of Mercury astronauts whose goal it was to beat the Soviet Union into space and eventually to the moon.

Drawing on extensive interviews with fellow astronauts, NASA engineers, family members, and friends of Gus Grissom, George Leopold delivers a comprehensive and corrective account of Grissom's life that places his career in the context of the Cold War and the history of human spaceflight.

Calculated Risk: The Supersonic Life and Times of Gus Grissom adds significantly to our understanding of that tumultuous and ultimately triumphant period in American history.

Key Points: -An insider's account of the U.S. Space Shuttle program, from before its first launch through the final landing, and the building of the International Space Station. -A firsthand account of life in space from the first human to fly seven missions. -An inspirational story of a personal journey from rural Indiana to outer space, powered by a deep Christian faith.

Williams has created a brilliant, nearly foolproof system of identification and verification. Two primary keys lead to eleven secondary keys that link to characteristic groups of tallgrass plants: seven groups for wildflowers and four groups for grasses. To identify a seedling, use the primary key to discover its place in the secondary key, then turn to that characteristic group to find your seedling. Circles on each full seedling photograph correspond to close-up photographs; triangles on these close-ups illustrate information in the text to further pinpoint identification. Drawings of leaves illuminate exact identification, and enlarged photographs of each seed provide yet another way to confirm identification.

Thousands of seeds were sprouted in the Tallgrass Prairie Center’s greenhouse to provide seedlings close in size and development to those grown in the field near the end of their first season; research and photography took place over four years. Williams’s text for each species includes a thorough description, a comparison of similar species, and guidance for germination and growth. A complete glossary supports the text, which is concise but detailed enough to be accessible to beginning prairie enthusiasts.

Anyone in the Upper Midwest who wishes to preserve the native vegetation of prairie remnants or reconstruct a tallgrass prairie of whatever size—from home gardens to schoolyards to roadsides to large acreages—will benefit from the hundreds of photographs and drawings and the precise text in this meticulously prepared guide.
