"In 2007, the Lunar Orbiter Image Recovery Project (LOIRP) began a process to convert the Lunar Orbiter Images directly from the original analog video recordings of the spacecraft data to digital image format, a change which provided vastly improved resolution over the original images released in the 1960s. The first of these restored images were released in late 2008."

  3. In the Beginning 1966-67 - five NASA spacecraft mapped the moon in unequaled quality 1986 - almost 2000 original 1960’s hi-def analog tapes were saved 2008 - last surviving tape drives were revived from oblivion Friday, June 12, 2009
  4. Lunar Orbiter Spacecraft Friday, June 12, 2009
  5. Lunar Orbiter Camera Two cameras: • High resolution 24” (610 mm) aperture • Medium resolution 8” (80mm) aperture Friday, June 12, 2009
  6. Lunar Orbiter Cameras Friday, June 12, 2009
  7. Spacecraft Film Scan Friday, June 12, 2009
  8. Imaging Process Friday, June 12, 2009
  9. Friday, June 12, 2009
  10. Lunar Orbiter Analog Tapes Friday, June 12, 2009
  11. Analog Tapes Friday, June 12, 2009
  12. Earthrise-1966 Friday, June 12, 2009
  13. Lunar Orbiter Tapes 1986 • Nancy Evans, a NASA scientist, was asked “What to Do With These Tapes?” • She ordered the tapes sent to JPL and located surplus tape drives • Project languished due to NASA’s lack of interest Friday, June 12, 2009
  14. Lunar Orbiter Tapes 2007 Friday, June 12, 2009
  15. Visit to Nancy’s Friday, June 12, 2009
  16. The Tapes Storage at a NASA JPL offsite climate-controlled storage facility Friday, June 12, 2009
  17. The Journey to McDonalds Tape Drives Tapes Arrival From Nancy’s from JPL at Ames Friday, June 12, 2009
  18. Friday, June 12, 2009
  19. Getting to Work Friday, June 12, 2009
  20. Drive Refurbishment Friday, June 12, 2009
  21. Techno-Archeology Friday, June 12, 2009
  22. Success! Friday, June 12, 2009
  23. Building an Image Friday, June 12, 2009
  24. Friday, June 12, 2009
  25. Earthrise 2008! Friday, June 12, 2009
  26. Friday, June 12, 2009
  27. Earth Detail Friday, June 12, 2009
  28. Earth Detail From Lunar Orbit Friday, June 12, 2009
  29. Quality Assessment Reproduced Images Match the Modulation Transfer Function of the Original 70mm Film ! Friday, June 12, 2009
  30. Manual Image Production Flow Friday, June 12, 2009
  31. Automated Production Friday, June 12, 2009
  32. Developing the Code Friday, June 12, 2009
  33. -&./01*(23405*$-5678$ !quot;#$%&''()*$+*,'*$ ?@/$+(*B$(*)A$ quot;5'2*$%&''A$+(*$ Notice the image shear, !quot;#%&''9:;+,;<=>?$.5@(2$ correlated with the nicks Notice the little nicks in the left edge No DFT DFT factor 1.0 First 2 frequencies Friday, June 12, 2009
  34. Got rid of the nicks but not the shear Got rid of the shear (yes, they were related) DFT Factor 1.25 DFT Factor 1.25 Friday, June 12, 2009
  35. 1 thru 4 are spread sheet tests, using actual data from runs. 5 is a record for a test in the image processing code, using the first synchronization bucket on this data set. Note the similarity to 4. The reason for the false signal before actual detection is the presence of a fiduciary marker in the data. Friday, June 12, 2009
  36. Second Image Life Magazine’s “Image of the Century” Friday, June 12, 2009
  37. Original vs Recovered Image The LOIRP Recovered Version Has Greater Tonal Variation Allowing for Measurements not Available Before Friday, June 12, 2009
