					<description><![CDATA[Col. Beausabre,

You NEVER know what&#039;s going to turn up at DRMO. I was poking around govdeals one afternoon and NASA was dumping a short ton of technical pieces, almost guarantee they wound up as scrap. 

I dearly hope there are NASA collectors who poke around that site.]]></description>

					<description><![CDATA[Col Beausabre is also correct.  NASA is like most organizations, and obsolete hardware and software is kept only for a certain amount of time before being discarded.  It is expensive to keep stuff, and if it is never going to be used again, there is no reason to keep it.  Fortunately, data is considered more valuable, but it is not well maintained (e.g. filed to modern file systems, especially before degradation sets in).  

Four years ago, an abandoned NASA spacecraft was attempted to by &quot;pirated&quot; by a group of citizens (with permission of its original owner, so it was not technically pirated).  Talking to it was a problem, as the NASA systems were already gone.  The group of citizens received quite a bit of help, from NASA, organizations, and fellow citizens.  
https://news.nationalgeographic.com/news/2014/06/140619-space-sun-nasa-astronomy-crowdsourcing/
&lt;blockquote&gt;There&#039;s a company we&#039;re working with called Ettus Research, and they have a piece of hardware that has software that emulates all of the hardware equipment NASA used to have.&lt;/blockquote&gt; 

Thank goodness that &lt;i&gt;someone &lt;/i&gt;can emulate at least some of NASA&#039;s obsolete equipment.  

This is not always the case.  Britain tried a &quot;Doomsday Project&quot; to celebrate the &quot;Doomsday Book&quot; after the Norman conquest of England.  The original 900-year old book still exists and can be read, with some interpretation of abbreviations and Latin, but the data collected on computer media for the celebration could hardly be read after a mere 25 years (where were PDFs when they were really needed?).  

&lt;blockquote&gt;In the proceeding quarter century, the technology became obsolete, making the content on the discs inaccessible to all but a few enthusiasts.&lt;/blockquote&gt; 

Wodun wrote: &quot;&lt;i&gt;Of course, there isn’t much glory in that for PI’s. But it would allow for endless study and discovery in the future.&lt;/i&gt;&quot; 

Isn&#039;t that why God gave us grad students?]]></description>

					<description><![CDATA[Wodun is quite correct. My understanding is that we have data that has never been analyzed and is stored on types of media and in types of formats (analog!) such that it is virtually unreadable today as no one makes the needed hardware or replacement parts any more   - if you are lucky enough to find what you need in an obscure corner - (or even if they were, no one knows how to fix a broken device or run it when fixed as the manuals were long since deep sixed) and no one is trained in the computer languages in question as they are long since obsolete. Not to mention the durability of some storage media such as tape, which deteriorates over time, making the physical existence of some data subject to an ever narrowing window. 

This gives some idea of the challenge

					<description><![CDATA[Voyager&#039;s Golden Record 
&quot;Dark was the Night, Cold Was the Ground&quot;
Blind Willie Johnson; December 1927
https://youtu.be/V8AuYmID4wc
3:24

&quot;Among those on the committee who chose the music for the disc was the cosmologist, astrophysicist and popularizer of all things astronomical Carl Sagan. The choices he and his colleagues made included the usual suspects — Bach, Beethoven, Mozart. But there’s also an odd little tune on the disc, recorded in 1927 by a Texan preacher and street-corner blues singer, Blind Willie Johnson. “Dark Was the Night, Cold Was the Ground”, adapted from an 18th-century hymn, is wordless, consisting only of Johnson’s slide guitar and his resonant, gospely, moaning hum. The song was picked by Sagan, who said it concerns a situation Johnson — and humanity — faced many times: “Nightfall with no place to sleep”.]]></description>

					<description><![CDATA[Building and launching them is a small pittance. The real costs are in transforming the data into something usable and in monitoring the spacecraft&#039;s operations. 

Perhaps AI will help with the data processing. A great problem to have would be so many probes gathering so much data that it sits in a memory bank in a usuable format but that no human had time to go through it all. 

Of course, there isn&#039;t much glory in that for PI&#039;s. But it would allow for endless study and discovery in the future.]]></description>

					<description><![CDATA[It still amazes me that of the 4 interplanetary/now interstellar probes that were launched in the 1970&#039;s we are still in communication with 2 of them and only lost touch with another (Pioneer 10) just a few years ago.

It further amazes me, and not in a good way, that we have only launched 1 more in all that time (New Horizons).]]></description>
