The Christine Williams loss of the Challenger crew still hurts even after 30 years, but our thinking Editor AIAA Bulletin was that many of the brightest minds in aerospace today were too young to remember the accident and the months of investigation that followed. We felt Contributing Writers there was value in providing fresh, unfiltered words about that chapter in Keith Button, Henry Canaday, spaceflight history.

  • The International Space Station and the Space Shuttle
    Order Code RL33568 The International Space Station and the Space Shuttle Updated November 9, 2007 Carl E. Behrens Specialist in Energy Policy Resources, Science, and Industry Division The International Space Station and the Space Shuttle Summary The International Space Station (ISS) program began in 1993, with Russia joining the United States, Europe, Japan, and Canada. Crews have occupied ISS on a 4-6 month rotating basis since November 2000. The U.S. Space Shuttle, which first flew in April 1981, has been the major vehicle taking crews and cargo back and forth to ISS, but the shuttle system has encountered difficulties since the Columbia disaster in 2003. Russian Soyuz spacecraft are also used to take crews to and from ISS, and Russian Progress spacecraft deliver cargo, but cannot return anything to Earth, since they are not designed to survive reentry into the Earth’s atmosphere. A Soyuz is always attached to the station as a lifeboat in case of an emergency. President Bush, prompted in part by the Columbia tragedy, made a major space policy address on January 14, 2004, directing NASA to focus its activities on returning humans to the Moon and someday sending them to Mars. Included in this “Vision for Space Exploration” is a plan to retire the space shuttle in 2010. The President said the United States would fulfill its commitments to its space station partners, but the details of how to accomplish that without the shuttle were not announced. The shuttle Discovery was launched on July 4, 2006, and returned safely to Earth on July 17.

Though more than a score of years after the loss of Challenger’s crew, STS-118 was a reminder of the morning of January 28, 1986. That week Christa McAuliffe planned to perform both live and filmed science lessons. These lost lessons, prepared for the nation and world’s school children, were never done. This project delves into those undone educational activities. Indeed, after studying its content, all will appreciate NASA’s, Christa’s and Barbara’s efforts as well as Bob Mayfield’s in carefully researching, preparing and training for the performance of the six “Challenger lost lessons.” Though lost in the sense that they perished with Challenger and her crew, recounting, redoing, and examining them is, in a sense, a resurrection.

From the time we flipped our calendars over to January 2014 to the moment our Centers flew their last missions in December, the strength of Challenger Center continued to reveal itself in truly magnificent ways. In just one year, we released two new standards-aligned simulated missions, opened two new Challenger Learning Centers, hosted unique special events to celebrate space exploration including numerous screenings of the hit film Interstellar, and made significant progress on a national research and development program to expand our reach into the classroom. We’re proud that this represents just a snapshot of our many successes from 2014. One of our most significant accomplishments was the opening of the Challenger Learning Center at the Scobee Education Center on the campus of San Antonio College. Opening a new Center is a huge undertaking for the staff and the community behind the Center. Together, we are all positively impacting more students as we expand our footprint across America and abroad. The Center at the Scobee Education Center marks the launch of our next generation simulated learning experience. Its new design offers students the environment to explore and learn with technology that meets their expectations. With every Center we open, mission we fly, and program we develop, our team is thoughtful to the Challenger Center mission and vision that was created nearly three decades ago and is still critical today.

  • Columbia and Challenger: Organizational Failure at NASA
    ARTICLE IN PRESS Space Policy 19 (2003) 239–247 Columbia and Challenger: organizational failure at NASA Joseph Lorenzo Hall* Astronomy Department/School of Information Management and Systems, Astronomy Department, University of California at Berkeley, 601 Campbell Hall, Berkeley, CA 94720-3411, USA Abstract The National Aeronautics and Space Administration (NASA)—as the global leader in all areas of spaceflight and space science— is a unique organization in terms of size, mission, constraints, complexity and motivations. NASA’s flagship endeavor—human spaceflight—is extremely risky and one of the most complicated tasks undertaken by man. It is well accepted that the tragic destruction of the Space Shuttle Challenger on 28 January 1986 was the result of organizational failure. The surprising disintegration of the Space Shuttle Columbia in February 2003—nearly 17 years to the day after Challenger—was a shocking reminder of how seemingly innocuous details play important roles in risky systems and organizations. NASA as an organization has changed considerably over the 42 years of its existence. If it is serious about minimizing failure and promoting its mission, perhaps the most intense period of organizational change lies in its immediate future. This paper outlines some of the critical features of NASA’s organization and organizational change, namely path dependence and ‘‘normalization of deviance’’. Subsequently, it reviews the rationale behind calling the Challenger tragedy an organizational failure. Finally, it argues that the recent Columbia accident displays characteristics of organizational failure and proposes recommendations for the future. r 2003 Elsevier Ltd. All rights reserved. 1. Introduction in 1967 are examples of failure at NASA that cost a total of 17 astronaut lives.
