On February 1, 2003, the unthinkable happened. The space shuttle Columbia disintegrated 37 miles above Texas, seven brave astronauts were killed and America's space program, always an eyeblink from disaster, suffered its second catastrophic in-flight failure. Unlike the Challenger disaster 17 years earlier, Columbia's destruction left the nation one failure away from the potential abandonment of human space exploration. Media coverage in the immediate aftermath focused on the possible cause of the disaster, and on the nation's grief. But the full human story, and the shocking details of NASA's crucial mistakes, have never been told -- until now. Based on dozens of exclusive interviews, never-before-published documents and recordings of key meetings obtained by the authors, Comm Check takes the reader inside the conference rooms and offices where NASA's best and brightest managed the nation's multi-billion-dollar shuttle program -- and where they failed to recognize the signs of an impending disaster. It is the story of a space program pushed to the brink of failure by relentless political pressure, shrinking budgets and flawed decision making. The independent investigation into the disaster uncovered why Columbia broke apart in the sky above Texas. Comm Check brings that story to life with the human drama behind the tragedy. Michael Cabbage and William Harwood, two of America's most respected space journalists, are veterans of all but a handful of NASA's 113 shuttle missions. Tapping a network of sources and bringing a combined three decades of experience to bear, the authors provide a rare glimpse into NASA's inner circles, chronicling the agency's most devastating failure and the challenges that face NASA as it struggles to return America to space.

> NASA’s public affairs staff churned out dozens of fact sheets, color brochures, and feature stories touting the scientific value of the research. But it was a tough sell. The experiments seemed second-tier to many outside observers. It was not that any one experiment represented demonstrably bad science. But given the half-billion-dollar cost of a shuttle flight, critics argued the price tag far outweighed the potential benefits. Even some in the shuttle program privately questioned the value of Columbia’s research.
> Columbia carried 13 rats, eight garden orb weaver spiders, five silkworms and three cocoons, four Medaka fish eggs, three carpenter bees, 15 harvester ants and an assortment of fish, mostly because students wanted to see how they would behave when weightless. One student experiment later attracted potshots from critics. Called “Fun with Urine,” the idea was to test the feasibility of urine-based paint as a possible way to redecorate future spacecraft, and thus stave off depression, on long-duration voyages.
> Crater analyses, like most of Boeing’s other shuttle production and operations tasks, had been done for years at the company’s Huntington Beach office. But responsibility for that and many other shuttle operations officially had moved from California to Houston earlier that month in an efficiency and cost-cutting move. As a result, Boeing engineer Paul Parker, who had been trained on Crater but had used the program only twice before, was assigned to help perform the analysis. Despite his inexperience, he knew enough about Crater to have concerns. The foam block that hit Columbia was estimated to have a volume of 1,200 cubic inches. That was at least 400 times greater than the largest foam cylinders used in impact tests to develop Crater.
> NASA engineers decided to simply remove the ramps and to install electric heaters to prevent ice buildups. The massive fittings that anchor the two struts holding the nose of the shuttle to the external tank—fittings that used to be buried inside the foam ramps—will be fully exposed on all future flights ( )
