In response to Steve Miller asking which astronaut this is, it is Edwin "Buzz" Aldrin ... but why they are using a NatGeo star chart is kind of scary!!! LOL
Also, I mentioned that L2 is getting crowded... NGR will be joining JWST and ESA's Euclid 1.2M space telescope. I had comparisons to make but ran out of time...complimentary missions in so many ways.
The other main areas omitted were the propulsion elements - hydrozine thrusters and reaction wheels for stability.
Stay tuned for the launch and mission performances of this great apparatus...!!!
Clear, Dark Skies...
