Lunar Orbiter Image Recovery Project Adventures in Techno-Archeology, Restoring Lunar Images for a New Generation of Exploration Friday, June 12, 2009

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

Lunar Orbiter Spacecraft Friday, June 12, 2009

Lunar Orbiter Camera Two cameras: • High resolution 24” (610 mm) aperture • Medium resolution 8” (80mm) aperture Friday, June 12, 2009

Lunar Orbiter Cameras Friday, June 12, 2009

Lunar Orbiter Analog Tapes Friday, June 12, 2009

Analog Tapes Friday, June 12, 2009

Earthrise-1966 Friday, June 12, 2009

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

Lunar Orbiter Tapes 2007 Friday, June 12, 2009

Visit to Nancy’s Friday, June 12, 2009

The Tapes Storage at a NASA JPL offsite climate-controlled storage facility Friday, June 12, 2009

The Journey to McDonalds Tape Drives Tapes Arrival From Nancy’s from JPL at Ames Friday, June 12, 2009

Getting to Work Friday, June 12, 2009

Drive Refurbishment Friday, June 12, 2009

Techno-Archeology Friday, June 12, 2009

Success! Friday, June 12, 2009

Building an Image Friday, June 12, 2009

Earthrise 2008! Friday, June 12, 2009

Earth Detail Friday, June 12, 2009

Earth Detail From Lunar Orbit Friday, June 12, 2009

Quality Assessment Reproduced Images Match the Modulation Transfer Function of the Original 70mm Film ! Friday, June 12, 2009

Manual Image Production Flow Friday, June 12, 2009

Automated Production Friday, June 12, 2009

Developing the Code Friday, June 12, 2009

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

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

Second Image Life Magazine’s “Image of the Century” Friday, June 12, 2009

Original vs Recovered Image The LOIRP Recovered Version Has Greater Tonal Variation Allowing for Measurements not Available Before Friday, June 12, 2009

Dennis: Add Sur veyor 1 Image Friday, June 12, 2009

OpenCL Enables deeper data sets including: • Multi Spectral Remote sensing • Real time navigation of images in 3D • Multi core data processing Friday, June 12, 2009
