[Milsurplus] OT: JPL Documentary on the Mars Exploration

[Gordon Smith]

Hi All,
If I may do a quick OT subject for anyone who is a Space Exploration 
geek like me. JPL recently created a wonderful documentary about 
their agency's exploration of Mars. It's really good, highlighting 
not just the science but the people and technical issues that they 
faced. Lots of behind the scenes video, photography and technical 
details I never knew about. One highlight for me was that the 
original Mariner 4 photo process was so slow that some engineers 
printed out one picture's greytone number data on strips, posted them 
to a wall, and manually colored in on top of the numbers to create 
what was the first crude photo of Mars.

The documentary is called "The Changing Face of Mars" and can be 
watched for free on Youtube. Link is here:
