When the U.S. space agency reorganized its mission enterprises last year, it combined all of its astronomy programs into a single program dubbed the Universe. Today, the Universe has more than a dozen space astronomy missions on orbit and at least that m
Quantitative relationships between changes in space shuttle weights and costs with changes in weight of various portions of space shuttle structural subsystems are investigated. These sensitivity relationships, as they apply at each of three points in the development program (preliminary design phase, det...
In arguing for this approach the authors take full advantage of the material available on the development of NASA's space shuttle program. This enables them to present a detailed account of the role of engineers in a very large, complicated project over a long period of time. In addition to...

has relied on the three-seat Russian Soyuz to ferry astronauts to and from the space station since even before the shuttle's retirement in 2011. While the cost per seat is significant, it is far less than the cost of a seat on the much more powerful, and more expensive, space shuttle....
The increased frequency of rocket launches is driven in part by rising demand for space-based technologies. And yet, despite of the need for more commercial satellites, the end of NASA’s space shuttle program in 2011 has had a negative effect in the space community. But even as NASA’s ...
The U.S. space program finds itself at a crossroads in many ways: the future of the Vision for Space Exploration, the balance of Earth and space science, International Space Station utilization, and the human space flight “gap”—all are to be decided, and soon. The question of what we...
