<table border=0 cellpadding=0 cellspacing=0 width="600"><TR><td bgcolor="#000000"><TABLE BORDER=0 cellpadding=4 border=0 cellspacing=1 WIDTH="100%"><TR bgcolor="#660000"><TD COLSPAN=2><CENTER>T O P I C     R E V I E W</CENTER></TD></TR><TR bgcolor="#494949"><TD valign=top>apollo16uvc</TD><TD>As far as we are aware, magazine Apollo 16 magazine AS16-123 has not been scanned in high resolution like most Apollo-era photos. This is a shame, because the Far Ultraviolet Camera/Spectroscope (Apollo 16 ALSEP Experiment S201 UVC) is still the only telescope on an other heavenly body. Like other Apollo magazines not online, or only in low resolution, it is a hole in space history.And to make matters worse, only a few scans are readily available. Here are the images found online so far: <UL TYPE=SQUARE><LI><A HREF="http://www3.telus.net/summa/faruv/" TARGET=_blank>Lunar Surface Astronomy</A> <LI><A HREF="http://www.masaakix.interlink.or.jp/apollo/d_apollo/apollo-16/ap16-exp-uv2.htm" TARGET=_blank>UVC (2) Spectrograph Apollo 16</A> <LI><A HREF="https://spaceflight.nasa.gov/gallery/images/apollo/apollo16/html/s72-40821.html" TARGET=_blank>S72-40821</A> <LI><A HREF="https://science.ksc.nasa.gov/mirrors/images/images/pao/AS16/10075873.jpg" TARGET=_blank>AS16-123-19657</A> <LI><A HREF="https://science.ksc.nasa.gov/mirrors/images/images/pao/AS16/10075874.jpg" TARGET=_blank>AS16-123-19650</A></UL> As you can see, these images appear to be low resolution scans of later generation copies and probably prints. So we decided to take matters into our own hands and <A HREF="http://nssdc.gsfc.nasa.gov/nmc/datasetDisplay.do?id=ASUV-00017" TARGET=_blank>ask NASA for the images</A>. We received the images, and what we got were completely non-standard files not readable by normal image software. They appear to be raw bit streams taken from the tape. Luckily, information on how they were scanned and saved is available. The <A HREF="https://babel.hathitrust.org/cgi/pt?id=mdp.39015059991854" TARGET=_blank>Revised S201 catalog</A> of far-ultraviolet objects has every image and inspects it in detail. A great source of information. (If you are a partner of babel, please download the entire document and send it to us!)After messing around with the files we received from NASA, we slowly but surely began to get recognizable images. We continued to tweak them, until we finally got acceptable results. Since these are uncompressed scans of first generation negatives, they are of much higher resolution and dynamic range than many images on the internet.We proudly present the files from NASA unconverted and converted to standard JPGs. This set includes UVC images taken on Apollo 16 and Skylab. <UL TYPE=SQUARE><LI><A HREF="https://archive.org/details/AS16-123-JPG" TARGET=_blank>Apollo 16</A> <LI><A HREF="https://archive.org/details/Skylab-S019-JPG" TARGET=_blank>Skylab</A></UL> In each image, the first 600 bytes were used for a header. We converted the first 600 bytes of each image to text which can be viewed here: <A HREF="https://drive.google.com/open?id=0BxS3Nsrmk63ebHRpbjZtMkNoamM" TARGET=_blank>Text</A> | <A HREF="https://drive.google.com/open?id=0BxS3Nsrmk63eNnI2dmo3c0s1RW8" TARGET=_blank>Excel</A>.If you come up with anything interesting, please share it with us!</TD></TR><TR bgcolor="#333333"><TD valign=top>Apollo-Soyuz</TD><TD>Here is a cover cancelled on the Apollo 16 moon landing date.

Asked to explain highlights of the instrument's findings for a general audience, Dr. Carruthers said "the most immediately obvious and spectacular results were really for the Earth observations, because this was the first time that the Earth had been photographed from a distance in ultraviolet light, so that you could see the full extent of the hydrogen atmosphere, the polar auroris and what we call the tropical airglow belt."</BLOCKQUOTE></TD></TR><TR bgcolor="#333333"><TD valign=top>holcombeyates</TD><TD>This is a great initiative.

The raw files were converted to jpegs by Thomas, you can view his work here.

Yes, if you have any documents please scan them, I'll upload them and credit you.

I have uploaded the photos to a Flickr album, which is much easier to view than the ancient Internet Archive viewer.
