Lunar Orbiter Image Recovery Project (LOIRP) Status 3 February 2014

Dennis Wingo Short status, February 3rd, 2014 evening.
Got through tape W1-068 today. That is 19 tapes today, bringing the total number of tapes left down to 219… Sixteen more to go to finish Woomera! I will post the tapes numbers and images in the morning….
Dennis Wingo Status, mid afternoon February 3, 2014
Just a few thoughts before the end of day status this evening. In January of 2014 we set a project record for tapes processed. We did 241 tapes in Jan. That is a LOT of tapes and we will never equal it because as of Friday, there were only 238 tapes left to go in the project!
Today we started with W1-049 and captured it again just in case as it is a spectacular image that we will be showing this week. Right now I am about to mount W1-060, meaning that this is the 11th tape of the day, bringing the total left to go down to 227. Since there are only 84 Woomera tapes in theory I will complete the last Woomera tapes of the project (except for cleanup).

Another productive day. Started out with W1-030 and ended with W1-049. That puts us more than half way through Woomera for LO-I!
We are going to have a couple of big surprises for you next week…
Here are the tapes done today and the images captured…
W1-030, complete capture LOI-189M
W1-031, complete capture LOI-190M
W1-032, complete capture LOI-178M
W1-033, complete capture LOI-177M
W1-034, complete capture LOI-175M
W1-035, complete capture LOI-176M
W1-036, complete capture LOI-162M

Quite a run of tapes today, twenty in all! If I can do this every day, which is what I was hoping to be able to do, I can finish the Woomera captures and start on Goldstone this coming week.
The remaining tape count today is 238…

Lunar Orbiter Image Recovery Project (LOIRP) Status 30 January 2014

Dennis Wingo Status, January 30, 2014, end of day.
Been a good day today! Finishing up tape W1-029 right now. This makes 16 tapes today. I finally figured out a system when capturing the medium resolution images and verifying that we are not missing a good high res image. I also figured out how to keep track of the frame lets for each medium res image and a way to enter it into one of our spreadsheets in a way that will make Austin happy. Here are the tapes and images captured today.
W1-014, complete capture LOI-113M
W1-015, complete capture LOI-121M
W1-016, complete capture LOI-123M
W1-017, complete capture LOI-125M
W1-018, complete capture LOI-144M
W1-019, partial capture LOI-204M,205M
W1-020, complete capture LOI-206M
W1-021, complete capture LOI-205M
W1-022, complete capture LOI-204M
W1-023, complete capture LOI-203M
W1-024, complete capture LOI-202M
W1-025, complete capture LOI-201M
W1-026, complete capture LOI-194M
W1-027, complete capture LOI-193M
W1-028, complete capture LOI-192M
W1-029, partial capture LO1-191M, complete capture 190M
Dropping 16 tapes off the list brings us down to 259 tapes to go. If the good lord willing and the head holds out I can finish Woomera before the end of next week…

Dennis Wingo Lunar Orbiter Status, mid afternoon January 29, 2014
Just a short status as the LO-I tapes take a lot of time and effort.
Getting a handle on finding where the medium resolution image actually is on a tape. Not as easy as it could be as the document that we have used very successfully on the other missions does not exist for LO-I.
I am basically taking the sequence numbers from the tape and finding where that sequence number was captured and then noting the frame let numbers for a medium resolution image. After looking at the first frame let of the tape I can figure out where the medium resolution image is on the tape with some guessing and playback effort.
So far we are on W1-012 today.
This brings the total left to go down to 275.

Lunar Orbiter Image Recovery Project (LOIRP) Status 27 January 2014

Dennis Wingo Lunar Orbiter Status, Monday January 27th 2014
Well, we have quasi completed Lunar Orbiter IV! I state it as quasi as we have found three additional tapes that will not play, no matter which head we use. It is our speculation that after a head was changed at the Madrid ground station that tapes M4-(53-55) somehow had a bad calibration that ended up with a bad recording. We speculate on this as tape M4-056 works just fine and there is no way that if the problem was related to an old vs new head that this would have happened.
Anyway we played tapes M4-(57-60) and tapes M4-(66-79) today. We are missing tapes 80 and 81 so we are done, that is until cleanup after we finish LO-I. We still want to go back and try these tapes again but for now we are done with LO-IV!
The tapes from 66-79 were all from the bad part of the spacecraft downlink where they were having problems so we did not get too much good stuff there, other than some gap filling to flesh out some missing frame lets in medium resolution images. I will put out the tapes vs images in a follow on post.
Here is an image of the first tape from Lunar Orbiter 1 sitting on the FR-900! Away we go!

Lunar Orbiter Image Recovery Project (LOIRP) Status 24 January 2014

Dennis Wingo Status end of day, January 24, 2014
Made good progress today, made it through M4-110 then backed up and started with M4-061. Made it through M4-065 at the end of the day.
This gets us down to 310 tapes to go!
(We are going to have a last tape party when we get to the end of the road here).
Dennis Wingo Status, afternoon January 24, 2014
I forgot to put out a status yesterday as I had to run out to San Francisco to a meet up yesterday.
Yesterday we made it through M4-102 and things look pretty good today as I am through M4-109 (slept through rush hour this morning after a late night last night). I am running M4-110 now and after my capture of M4-111 last week this finishes the numerical series. However, we still have M4-53 through M4-079 to complete.
Some bad news is that we are missing two additional Madrid tapes from LO-IV, M4-080 and M4-081. This brings us to a total of six LO-IV Madrid tapes that are missing and this is by far the most missing tapes that we have for any mission. Very sad about this as we are getting some really nice images, as we see with the honor of the Wired image of the day today for LO-IV-123M!
I should have time today to go back and see how many in the 53-79 series that I can get. Another annoyance is that most of the tapes I have today are from the two pages that are missing from the table from the book we just got so I can’t even tell you what images we have from today’s captures. Here is what we got yesterday.
M4-094, complete capture LOIV-163M, partial capture 164H
M4-095, partial capture LOIV-164H (completes image), complete capture 162M, 163H
M4-096, not needed, duplicate capture of G4-082
M4-097, partial capture LOIV-143H (completes image with overlap of tape W4-097)
M4-098, complete capture LOIV-141M, 142H (141M is a blank image)
M4-099, complete capture LOIV-140M (skipped 141H as it is blank)
M4-100, complete capture LOIV-139M, 140H
M4-101, complete capture LOIV-138M, partial capture 139H
M4-102, partial capture LOIV-139H (completes image), complete capture 137M, 138H
M4-103, complete capture LOIV-136M, 137H
M4-104, complete capture LOIV-135M, 136H, 134M
That’s all that I have data on…..

Lunar Orbiter Image Recovery Project (LOIRP) Status 22 January 2014

Dennis Wingo: Status, afternoon January 22nd, 2014
It’s Alive…….
Looks like we are able to move forward. The head that we are currently using is still functioning. Today I have captured M4-082 through 090 which is on the machine now. If things continue going I will get through at least M4-092 today.
It must be noted that I skipped M5-53 to M4-081. The head that was replaced on the Madrid machine 46 years ago won’t work with our worn head, but by the time we reached tape M4-082 the head wear was such that we could lock up on the signal.
It is my plan to proceed through to finish out the tapes and by then we will have another head that is currently being repaired (not refurbished) by Videomagnetics. If that head works we will be able to finish LO-IV and start immediately on LO-1.
If we get the tapes done today that I think we will we will have 333 tapes to go by the end of the day!
Dennis Wingo: Update, Wednesday late afternoon, January 22nd, 2014
We got the Lunar Orbiter photography book yesterday, sans to critical pages in the table that we use for matching the sequences to the tapes. However, I can still provide the data for the tapes that we are running today in the form that we did for Lunar Orbiter II, III, and V.
Tapes for Today
M4-082, partial capture LOIV-195H, complete capture 193M, 194H
M4-083, complete capture LOIV-192M, 193H, partial capture 191M
M4-084, partial capture LOIV-191M (completes image), complete capture 192H
M4-085, complete capture LOIV-190M, 191H
M4-086, complete capture LOIV-189M, partial capture 190H (completes image with framelets from G4-072)
M4-087, partial capture LOI-171M (completes image with frame lets from W4-087)
M4-088, Complete capture LOIV-169M, 170H
M4-088, Complete capture LOIV-168M, 169H
M4-089, Complete capture LOIV-167M, 168H
M4-090, Complete capture LOIV-166M, partial capture 167H
M4-091, Complete capture LOIV-165M, 166H
M4-092, Complete capture LOIV, 164M, 165H, partial capture 167H (completes image)
M4-093, Complete capture LOIV-164M, 165H (next tape up)
If we get through all of these tapes (M4-092 is running now), we will have 332 tapes to go!

Lunar Orbiter Image Recovery Project (LOIRP) Status 21 January 2014

Dennis Wingo: Status, afternoon January 21, 2014
It’s dead Jim….
The head that is on the FR-900 right now has been running for about 150 hours. It’s tip projection is below the recommended minimum for the lunar orbiter tapes. When the Madrid ground station changed their head after M4-52 the machine quit working. After much pain and suffering and scratching of heads Ken and Terry Smith, another old hand figured out that as the tip’s wear down the velocity changes ((pi*r^2)). Due to the fact that the Lunar Orbiter tapes have a signal that must be demodulated accurate to one hertz, this presents a problem. We have quasi proved this by taking tape M4-111, the last tape for Madrid, putting it on the machine, and adjusting the tip penetration out as far as it will go. That tape is playing back.
This won’t work for all of the tapes and thus I will now work backward from M4-111 to see how many I can get done….
As captain Taggart would say…
Never Give Up! Never Surrender!

Dennis Wingo Status, end of day, Friday January 17, 2014
We completed Madrid tape M4-052 yesterday, which gets us almost half way through the Madrid captures… That’s the good news.
The bad news is that the ground station changed heads yesterday and now our head is not working. It was at the end of the day and we will figure out what the changes were on Monday.
It’s always something!

Lunar Orbiter Image Recovery Project (LOIRP) Status 16 January 2014

Dennis Wingo: Status, near end of day, January 16, 2014.
A very good day today. Came in early today and with several of the blank images that we have seen in the other ground station tapes, we have been able to get through a lot of tapes. AT the end of the day today we will finish M4-033! Running M4-032 now and will do one more before I leave.
That is 23 tapes today, bringing the number of tapes to go down to 346!
Just as an FYI we have 110 Madrid tapes so that is 67 (edit: miscount— 77 to go) tapes to go to finish out Lunar Orbiter IV.
If everything holds out, we may finish Lunar Orbiter IV by next Friday. Then on to the final Orbiter, Lunar Orbiter 1!
Two interesting photo’s today. The first is from a guy named Leo and he says hi to everyone from 1966. That was written on the inside of the cover of one of the tapes from Goldstone. The second is the stack of Lunar Orbiter IV tapes that are completed. They are ten high except for a couple stacks so you can figure out for yourselves how many we have done!’

Dennis Wingo Lunar Orbiter Status, end of day, January 15, 2014
Well we finished Goldstone and got a good start on Madrid today. As expected there are more head clogs and there are several blank or fogged images in the beginning.
We made it through M4-009 today. That is six more tapes since the last report earlier today, bringing the number of tapes remaining down to 369!
Can you tell I am thrilled to get to this point?

Lunar Orbiter Image Recovery Project (LOIRP) Status 14 January 2014

Dennis Wingo Status, late day, Tuesday January 14, 2014.
Came in early today and started on G4-081. Am just finishing up on G4-093. Almost all of the captures today were very long, over 40 minutes and some almost an hour. Captured several hundred gigabytes of images.
The count is now 385 tapes to go!
(Good lord willing and the head holds out of course)
