  1. Computers and Space Exploration! By: Riley, Mico, Hunter

  2. Brief Overview • Riley- Space race history computers • Mico- Present space exploration computers • Hunter- Special topic: Curiosity Mars rover systems

  3. Space Exploration Back In The Day!

  4. Sputnik • 1950’s • USSR Space Program • Sputnik 1 • Sputnik 2

  5. The Apollo Missions • America is awesome! • To the Moon!

  6. Moon landing Issues • Lots of math involved • Human error • Lives on the line • Computers offer a solution!

  7. The AGC • AGC= Apollo Guidance Computer • 1960’s Moon Landings • Unsophisticated computers • Special language designed by MIT • Converted into assembly language • Used punch cards • Most complex program of mission was 6Mb. • Smaller than PowerPoint • Most sophisticated program of it’s day

  8. Space Exploration Today!

  9. The Space Shuttle • Cornerstone of manned spaceflight • Responsible for launching of satellites

  10. IBM Ap-101 • 5 IBM 32-bit general purpose computers (Gpu’s) • 4 computers w/specialized software operations • Primary Avionics Software System (PASS) • 1 extra computer running backup flight software

  11. NASA aims for perfection • Independent verification and validation • Highest achievable levels of cost effectiveness & safety • For mission critical software

  12. Computing information and Communications Technology. • Develop technologies for: • Space and Aviation applications • Intelligent communications • Data gathering • Operational systems

  13. Mars rover Curiosity

  14. Rover mission • Investigation of: • Martian Climate • Martian Geology • Weather assessment • Environmental conditions • Favorable for Microbial life • Planetary habitability

  15. The Technology behind the rover • Surprisingly Low numbers… • Two on board computers with: • 256 kb of EEPROM • 256 MB of DRAM • 2 GB of flash memory • Both are radiation hardened • One serves as backup

  16. On board facilities • On board Science Lab • Laser sensors • Transmits findings back to Earth • Navigation Computer • Brand new surface exploration software • This includes: • Sensor navigations • Inputs received from sensors • Computations • Where to move • Sample analysis

  17. The End!Questions?
