I am reading the book "Elon Musk" a biography and several things hit me well. One is that our industrial might has long since been gone from the 1940's. As such, I went to New Mexico attracted to strengthening that industrial might.
Also, our talented engineers are focused rather than solving world problems, on making money, often drawn to software and financial industries.
Here are some posting based on reconfiguring satellites in space, based on small payloads rather than large payloads.
Unfortunately, my experience with the industry is that a person could wait 7 years to launch their work, and their work might be part of phase 12 of 17. If phase 1, failed or the launch failed, that person would have to wait another 7 years for a next launch. Elon Musk seems to be determined to bring the agility of Silicon Valley to the aerospace industry. A noble quest.
I also saw a large amount of fluff, with no substantial technology behind it, which was a turn off to this industry. Real break throughs and transparency are important to me.
Implementing Data Reduction Techniques in
gurable Computing Platforms
As far as solar technologies, while at ITT, in 2008, I worked with peers to create a proposal for a Broad Agency Announcement (BAA). We created a satellite design exploring capabilities of hybrid power systems involving solar power and electromagnetic tethers. We proposed methods for propelling the satellite using electromagenetic and momentum tether configurations to avoid the need for rocket fuel.
