  1. Terra at 10 The EOS Flagship Eric Moyer NASA/Goddard Space Flight Center Greenbelt, Md. 20771 Photos provided by Al Lampe May 11, 2010 Goddard Space Flight Center

  2. The satellite’s name “Terra,” meaning Earth, was the winning entry in a nationwide student essay contest won by a high school student from St. Louis, Missouri.

  3. A Walk down Memory Lane…. What did it take to build Terra?

  4. Primary Structure

  5. Communications Equipment Module

  6. Power Equipment Module Batteries

  7. Solar Array

  8. The equipment modules were then integrated on to the Primary Structure The equipment modules were then integrated on to the Primary Structure Communications Equipment Module Power Equipment Module Primary Structure

  9. Thermal Control Subsystem

  10. Guidance Navigation and Control Subsystem

  11. Guidance Navigation and Control Subsystem Star Trackers Reaction Wheel Assembly

  12. Propulsion Subsystem

  13. Flight Software and Simulators

  14. Navigation TDRS On-board Navigation System (TONS) Performance has exceeded requirements

  15. The Instruments

  16. ASTER Instrument METI and ERSDAC, Japan

  17. CERES Instrument Langley Research Center, Virginia

  18. MISR Instrument Jet Propulsion Laboratory, California

  19. MODIS Instrument Goddard Space Flight Center, Maryland

  20. MOPITT Instrument Canadian Space Agency and University of Toronto, Canada

  21. So what did it take to build Terra? A lot of dedication, technology and teamwork!!!

  22. View of Terra Equipment Modules Technology and Teamwork

  23. View of Terra Instruments Technology and Teamwork

  24. Technology and Teamwork Terra Spacecraft was built by Lockheed Martin at the Valley Forge, Pennsylvania facility and managed by NASA Goddard Space Flight Center

  25. Terra moved to the launch site in California

  26. Spacecraft on Transporter with Frame

  27. Spacecraft on Transporter bagged for shipment

  28. Terra Spacecraft Transportation Container

  29. Terra flew on a C-5 aircraft from Dover Air Force Base, Delaware to Vandenberg Air Force Base, California, where it was processed and launched.

  30. C-5 on Final Approach to Vandenberg

  31. The Solid Rocket Boosters arrive at Vandenberg

  32. Transportation System outside Payload Processing Facility at Vandenberg AFB, California

  33. Shipping container entering Payload Processing Facility

  34. Removing Shipping Container Cover

  35. Removing Frame

  36. Terra spacecraft being prepared for installation on its Three-Axis Positioner (TAP) TAP

  37. Final Check-up/Pre-launch Testing

  38. Propulsion Leak Testing

  39. Contamination Inspections

  40. Inspecting the MODIS instrument lens for dust

  41. Inspecting and Cleaning

  42. After testing and inspections, Terra received a “GO FOR LAUNCH”!

  43. Preparing Terra for positioning on its Payload Adapter Terra: Weight – 5190 kg Diameter – 3.5 meters Length – 6.8 meters

  44. Terra mounted to its adapter is then installed in a Launch Vehicle Fairing. Fairing Adapter

  45. The Fairing was positioned on top of the Atlas rocket inside the building.

  46. Terra Launch December 18, 1999

  47. Terra’s systems and Instruments were checked successfully and declared operational.

  48. Terra Today

  49. Taking Care of Terra • The Flight Operations Team (FOT): • evaluates Terra’s health and safety, 24 hours a day, 7 days a week, • performs 27-28 contacts thru TDRS daily • ensures that all the science data are downlinked (99.05 % data capture) • maintains Terra’s orbit by doing maneuvers • 25 Inclination Maneuvers • 58 Drag Make Up Maneuvers • The instrument teams work with the FOT to manage the operation of the instruments.
