in space (Deep Space 1) was developed from Code TI, as is the MAPGEN software that daily plans the activities for the Mars Exploration Rovers, the same core reasoner is used for Ensemble to operate Phoenix Lander, and the planning system for the International Space Station's solar arrays. Integrated System Health Management for the International Space Station's control moment gyroscopes, collaborative systems with semantic search tools, and robust software engineering round out the scope of Code TI's work. The Human Systems Integration Division "advances human-centered design and operations of complex aerospace systems through analysis, experimentation, and modeling of human performance and human-automation interaction to make dramatic improvements in safety, efficiency and mission success". For decades, the Human Systems Integration Division has been on the leading edge of human-centered aerospace research. The Division is home to over 100 researchers, contractors and administrative staff. The NASA Advanced Supercomputing Division at Ames operates several of the agency's most powerful supercomputers, including the petaflop-scale Pleiades, Aitken, and Electra systems. Originally called the Numerical Aerodynamic Simulation Division, the facility has housed more than 40 production and test supercomputers since its construction in 1987, and has served as a leader in high-performance computing, developing technology used across the industry, including the NAS Parallel Benchmarks and the Portable Batch System (PBS) job scheduling software. In September 2009, Ames launched NEBULA as a fast and powerful Cloud Computing Platform to handle NASA's massive data sets that complied with security requirements. This innovative pilot uses open-source components, complies with FISMA and can scale to Government-sized demands while being extremely energy efficient. In July 2010, NASA CTO Chris C. Kemp open sourced Nova, the technology behind the NEBULA Project in collaboration with Rackspace, launching OpenStack. OpenStack has subsequently become one of the largest and fastest growing open source projects in the history of computing, and has been included in most major distributions of Linux including Red Hat, Oracle, HP, SUSE, and Canonical. Image processing NASA Ames was one of the first locations to conduct research on image processing of satellite-platform aerial photography. Some of the pioneering techniques of contrast enhancement using Fourier analysis were developed at Ames in conjunction with researchers at ESL Inc. Wind tunnels The NASA Ames Research Center wind tunnels are known not only for their immense size, but also for their diverse characteristics that enable various kinds of scientific and engineering research.
