In the decades after the Apollo program, American space shuttles flew over 130 missions and successfully completed over 98 percent of them, but unfortunately, the two most famous missions were the ones that ended tragically aboard the Challenger and Columbia. The Space Shuttle Challenger Disaster: The History and Legacy of NASA’s Most Notorious Tragedy chronicles the disaster from the origins of the Challenger mission to what went so terribly wrong.

On April 24, 1990, the Space Shuttle Discovery lifted off from Kennedy Space Center on the Space Shuttle Program’s 35th mission, but this was no ordinary mission. In its payload bay, Discovery was carrying the Hubble Space Telescope, with the objective of putting the telescope into orbit.

The Cold War is usually thought of in terms of fear, potential nuclear war, and espionage. While these were elements of the years between the end of World War II and the 1990s, the competition between the US and the USSR had some real benefits. Perhaps, the best and most impressive accomplishments during this time resulted from the Space Race.

Life in Space explores the many aspects and outcomes of NASAs research in life sciences, a little-understood endeavor that has often been overlooked in histories of the space agency. Maura Mackowski details NASAs work in this field from spectacular promises made during the Reagan era to the major new directions set by George W. Bush's Vision for Space Exploration.

By the time the Hubble telescope reached orbit, it was already the world’s most famous telescope, but it was also the most scorned. The telescope cost nearly two billion dollars more to complete than anticipated, and to make matters worse, the first images it sent back were skewed. However, within about a year of fixing it, the telescope captured images of a major event in the solar system.

During the Age of Exploration, Native American tribes fell victim to European conquerors seeking legendary cities made of gold and other riches, attempts that were often being made in vain. And yet, of all the empires that were conquered across the continent, the one that continues to be most intimately associated with legends of gold and hidden riches is the Inca Empire.
