Dennis Wingo: Doing a bunch of clean up today, paperwork and processing framelets! That, to us, amazing image of the horizon from LOV-041, was a highlight. Austin is processing the entire medium resolution image and it should look great in full resolution.
We did run one tape today as the medium resolution image LOV-041m was spread across two tapes and was missing a few framelets. So our head, like Wesley in the movie princess bride, is just mostly dead. We use it when we absolutely have to in order to grab critical pieces of images. So we processed tape G5-145 today. Since we only needed a few framelets off it it, that one is considered done as it overlapped W5-154 and W5-155 and W5-018. Looks like this may help prove the thesis of a lot of overlaps in LOV. It was easy to tell the overlap as the capture time from all of the ground stations is in GMT time.
Here are the images for the tapes that were run last Thursday and Friday that are not recorded yet.

It annoys me that toward the end here they changed tapes in the middle of a high resolution or medium resolution frame, even though the missing pieces are found on other tapes.
LOIRP Status Report 7-8 August 2013
Dennis Wingo: End of Day August 8, 2013
Lots of tapes done today. Got all the way from W5-143 to W5-158. Not quite as good as it looks as we already had captured 156 and 157 early in the year, they being the tapes for LOV-041 the oblique crater Messier and Messier A. We have five tapes to go tomorrow and we will be done with Woomera tapes for LOV!
Then as soon as Austin gets the report together on the framelets captured we will start on the Goldstone LOV tapes. I have already opened a couple of cans and it looks like they started getting data a few days earlier….
Ok, tapes and images for today…
W5-143, partial capture LOV-067H, complete capture 065M, 066H
W5-144, partial capture LOV-064M, complete capture 065H

Will do the rest in the morning, found an error in the original NASA document but need time to figure out.
Five more to go for Woomera LOV!
Mid Day, August 8, 2013
Running tape again today. Lots of looong captures….. Running W5-148 right now. Hope to get into the mid 50’s today and be done with Woomera tomorrow!

LOIRP Status Report 6 August 2013
Dennis Wingo: Got a lot of tapes done yesterday but the accounting is getting more difficult due to the overlaps now between the priority readouts and the final readouts.
This is shortening the amount of tape that has to be run but it is also going to make Austin’s job of piecing the images together more difficult as well.
W5-111, complete capture LOV-142M,143H
W5-112, partial capture LOV-141M, 142H
W5-113, complete capture LOV-123M, 124H, partial capture 122M
W5-114, partial capture LOV-122M, 122H, complete capture 123H, 121M
W5-115, partial capture LOV-122H (completes image)
W5-116, partial capture LOV-120M, complete capture 121H
W5-117, partial capture LOV-119M, 120H
W5-118, complete capture 118M, partial capture 119H (completes image) [image overalp with W5-042]
W5-119, partial capture LOV-117M [image overlap with W5-042], partial capture 118H
W5-120, partial capture LOV-118H
W5-121, partial capture LOV-116M, 117H
W5-122, partial capture LOV-116H [image overlap with W5-043],
W5-123, complete capture LOV-114M, 115H, partial capture 113M
It is going to get a lot more complicated from here on out. As I suspected there is considerable overlap both within a single ground station readout (priority readout vs final readout, but we have to deal with the same thing from the other ground stations.
We are already up to W5-133 today due to the overlaps. This is good, but it makes our lives more difficult in accounting!
LOIRP Status Report 5 August 2013
Status Monday end of day. We got up through W5-123 today, 13 tapes, a good day. What we have started to find is overlaps between the priority readout and the final readout. I figured this considering the number of tapes we have but this will lower the number of tapes we have to run. We saved about 150 framelets or one long tape spread over three tapes today. Saves head life as well!!
Tomorrow morning we will skip an entire tape and start on W5-125.
That means we have 36 or fewer tapes to go to finish Woomera this week!
Mike Wargo
Keith’s note: According the NLSI Twitter: “NASA’s chief exploration scientist, Mike Wargo, passed away unexpectedly yesterday. We will miss his leadership and friendship enormously.” I’ll post more information as I receive it. Very sad – Mike was such a nice person and believed in space exploration in a very personal way. He was also a big supporter of the LOIRP.
NASA Lunar Exploration Analysis Group Statement on the Passing of Dr. Michael Wargo
“The Lunar Exploration Analysis Group (LEAG) on behalf of the broader lunar community wishes to expresses its deep shock and sadness at the news that Dr. Mike Wargo passed away unexpectedly over the weekend of August 3-4, 2013. Mike was the Executive Secretary of LEAG and championed the Moon at NASA HQ.”
Keith’s update: This note is being circulated within and outside of NASA: “With deep sadness, I must tell you that our friend and colleague, Mike Wargo, passed away unexpectedly over the weekend. This news comes as a great shock to us all, and he will be missed terribly. In our grief, let us remember how Mike inspired us with his inexhaustible energy and enthusiasm, his hearty laugh and booming voice, and his dedication to NASA. Mike was HEOMD’s chief exploration scientist, and his contributions to human exploration were many. He represented the directorate on the science teams for the Lunar Reconnaissance Orbiter and LCROSS missions, and most recently, he was a member of the Mars 2020 Science Definition Team. Mike led by example, working closely with colleagues in the lunar, planetary, and Mars science communities, to build collaborative and highly productive projects for both Exploration and Science. Please keep his wife Adele and his family in your thoughts and prayers during this difficult time. We will let you know about plans for the funeral and a NASA memorial service once they have been made.”
Lunar Orbiter Tracking Stations
Dennis Wingo: We often talk about the ground stations for Lunar Orbiter. Here is a chart that shows the coverage of the DSIF (Deep Space Instrumentation Facility) the precursor of the Deep Space Network (DSN). for Woomera, Goldstone, and Johannesburg. In 1965 when this graphic was created, the Madrid station was still under construction. You can see the overlap between Woomera and Goldstone quite clearly. Out to lunar distance the overlap is even greater. Larger image.
LOIRP Status Report 2 August 2013
Dennis Wingo: These are the tapes we processed in the past three weeks. (larger image). Wow, when the week started, I started capturing tape W5-38. At this moment tape W5-110 is playing. However, tapes 53-62 and tapes 99-104 had been previously captured. So subtract 15 tapes and we have 58 tapes captured this week. That certainly is a record for the project. Here are the tapes captured today.
W5-095, complete capture LOV-176H
W5-096, complete capture LOV-174M, 175H
W5-097, partial capture LOV-173M, complete capture 174H

W5-101 (captured earlier in year)
W5-102 (captured earlier in year)
W5-103 (captured earlier in year)
W5-104 (captured earlier in year)
W5-105, partial capture LOV-134H (completes image), complete capture 132M

W5-109, partial capture 130H (completes image), complete capture 128M
W5-110, partial capture 129H, complete capture 127M
It is my goal for next week to complete the captures for LOV-Woomera. That will be 51 tapes, a few less than this week.
A project record.
NASA Technoarchaeology at University of Alabama Huntsville
University of Alabama Huntsville: With billions of dollars of past space research at risk of being lost forever, Dr. Charles Lundquist is running a race against technology and time.
Director of the Interactive Projects Office at The University of Alabama in Huntsville’s Research Institute, the 85-year-old Dr. Lundquist spent 40 years in high-level positions with the U.S. Army, the Army Ballistic Missile Agency, NASA, and finally the University of Alabama in Huntsville. He officially retired in 1999. Working as a volunteer since then, he spends his time sleuthing for past research from the Army, NASA and private papers, as well as collecting oral histories from NASA retirees and others. All are added to an archive on the ground floor of UAH’s M. Louis Salmon Library, where Anne Coleman is a reference librarian and head of Archives and Special Collections. The archives preserve continued access for future historians, scholars and students.
Image: Dr. Charles Lundquist, director of Interactive Projects at the UAH Research Center, and Anne Coleman, reference librarian and head of Archives and Special Collections, with obsolete media containing data from the U.S. space program. The IBM printout that Dr. Lundquist is reading is the only surviving copy of the telemetry he needed for research from NASA’s Gravity Probe A mission. The original tape from the 1976 flight is no longer readable. Larger image

LOIRP Status Report 30 July 2013
Dennis WIngo: Status, end of day 7-30-13: As I may have mentioned in the past, we have captured some lunar orbiter five images before this concentrated run. The Copernicus mosaic we did a few months ago, the Messier craters and some other images we had captured before.
So today I started with W5-051 and 052. Then we skipped all the way to W5-063. Then we skipped W5-064 and began again with 065. Today we have captured 12 tapes, going through W5-073. Tomorrow I will list the images but it takes a while to figure out from the paperwork.
Hopefully, if we can keep this pace up we will be over W5-100 on Friday and then we have another several tapes to skip! We won’t know what we have to do with the Goldstone and Madrid tapes for LO-V until we are completely finished with Woomera. So, there you have it….
Status mid day 7-30-13: These are the images captured from the tapes run Saturday (2) and Monday (13). We made it through LOV-50 through the end of yesterday and with what we have run today we are more than 1/3rd the way through LOV Woomera tapes now.
W5-036, partial capture LOV-096H, 095H, complete image 094M
W5-037, partial capture LOV-099M, complete image 100H

W5-050, partial capture LOV-127H (completes image), partial capture 126H, complete image 125M
Today we have run several tapes but we are jumping sequence due to our having captured several tapes between W5-53-62. I need to verify all of them before we leave them behind though. Will report on our progress today at the end of the day. Looks like we will do about ten tapes today and get us up to W5-70, if everything holds together.
Venture Capitalist Steve Jurvetson Supports LOIRP
SN Profile: Steve Jurvetson, Managing Director, Draper Fisher Jurvetson (DFJ), Space News
“Steve Jurvetson loves rockets. The well-known Silicon Valley venture capitalist, who attended camp at NASA’s Kennedy Space Center as a child, shares images of the rockets he launches in Nevada’s Black Rock Desert on a Flickr Photostream. … Jurvetson, who sits on the board of SpaceX and Tesla Motors, both founded by Elon Musk, also donates money to space-related organizations, including the B612 Foundation, a group preparing to map near-Earth asteroids, and the Lunar Orbiter Image Recovery Project, an effort to create a digital archive of data drawn from the analog tapes of Apollo missions.”
Priority vs Final Readout of Lunar Orbiter Images
Dennis WIngo: This image (click on image to enlarge) shows the sequence of images that were read out during what is termed “priority” readout vs the “final readout”. The priority readout was an opportunistic scanning of processed photos on the lunar orbiter before all of the images were taken. The photo process with the 70mm film began with an image being simultaneously taken by the 610 mm high resolution camera and by the 80 mm medium resolution camera. In a process remarkably similar to the old polaroid dry process instamatic cameras, the film was dry processed by a “bimat” dry processor. The bimat would separate from the film (most of the time) but would sometimes due to the timing would leave artifacts on the image, which are readily identified on the film.
The film would then be fed into the readout looper where it could be scanned and the images sent back to the Earth. During the mission when photographs were still being taken the film would run one direction through the looper. After all of the images were taken a command would be sent to cut the bimat and then the film could be read in the opposite direction.
Thus when we start with a low numbered tape, the first images that come off are from the priority readout in ascending order. However, the ascending order is not linear, jumping because images are still being taken and the film advancing while the spacecraft cannot transmit. The image of the day today shows what images are taken in ascending sequence (orbit) format. You can see the jumps. If you are really good you can see what images we are recording and then predict what the next images will be … At least during the priority readout.
How Do We Find Lunar Orbiter Images?
Dennis Wingo: Several people were interested in our process yesterday so here is some more information on what we do to figure out the images on the tapes. [Click on image to enlarge].
We almost always start with the low numbered tapes and go up, just like in the real mission. As stated yesterday, we picked Woomera because it had the most ground station time. There is 163 tapes for the Woomera LO-V, more than 50-60 tapes than for the previous LO’s. We think that there is some duplication there but we won’t know until we get all of the Woomera tapes done, then process the raw framelets. Austin then generates a report based upon our knowledge of all of the framelets for LO-V, which then tells us what we have left to do. We then will start on the Goldstone tapes.
