NASA's Movement Towards Cloud Computing
The NASA Nebula Project provides a cloud computing platform that addresses NASA's challenge of a fragmented and inefficient IT environment. Nebula offers scalable computing resources that researchers can access easily to perform data processing and analysis. This overcomes limitations of local servers and supercomputers. Early users report being able to accomplish more data-intensive work faster using Nebula. The platform is based on OpenStack, an open source cloud software project.

NASA’s IT ChallengesAsa result of NASA’s diverse mission and distributed workforce (across centers, labs, and universities), we have a uniquely balkanized – and expensive - IT environment.Typical Enterprise IT infrastructure is only utilized to 5-20% of its capacity1NASA’s Supercomputers are also only available to the largest projects, with small projects often waiting many weeks in queue… many jobs do not require HPC.Thousands of new computers are inefficiently procured and operated each year, continuing the cycle. This process often takes many months and costs more in overhead than the actual value of the computers.1 Source: http://www.eecs.berkeley.edu/Pubs/TechRpts/2009/EECS-2009-28.pdf 4National Aeronautics and Space Administration

Editor's Notes
- #3 The launch of the first artificial satellite by the then Soviet Union in 1957 marked the beginning of the utilization of space for science and commercial activity. During the Cold War, space was a prime area of competition between the Soviet Union and the U.S. In 1964 the first TV satellite was launched into a geostationary orbit to transmit the Olympic games from Tokyo. Later, Russian launch activities declined while other nations set up their own space programs. Thus, the number of objects in Earth orbit has increased steadily -- by 200 per year on average. The debris objects shown in the images are an artist's impression based on actual density data. However, the debris objects are shown at an exaggerated size to make them visible at the scale shown.
