8/27/21: Updates including a new analysis; view video on attenuation bias

      1. Updates:

• MH: The paper was finally resubmitted for the last time.
• PT: Conference asked him to send a video presentation of the paper. He will make a video presentation in powerpoint and send to them. He will send it so us for approval/comments first and at some point we should play it for this meeting, maybe even in time for revisions.
• SD: Showed an analysis of astronauts broken down by gender. 
• Financials. 
• MH paper: He sent them the payment. The appropriate people need to send him their share.
• As of 6/25/21, PT paid $400 for FTC and the college has agreed to reimburse him for it. 

2. Reading and discussion:

• We viewed https://youtu.be/Pz4ephK-f94. Attenuation bias is an issue when there is error in the independent variable but not in the dependent variable. For spacecraft, launch date as an independent variable has little error. But failure date has more error because it is influenced by lifetime, which has some ambiguities (i.e. error) for some spacecraft. 
• Hu et al. 2015, A survey on life prediction of equipment. We got up to section 3.2.2, item (3) last time, and did not read anything more this time, so we can start there next time.

---------------------------------------Below are some ideas for future discussion----------------------

• We found that the paper at https://link.springer.com/chapter/10.1007/978-3-030-40896-1_3 seems like a good paper for us to read.
• MH suggests a short book called Future Spaceflight Meditations, a cosmist perspective, by Jiulio Prisco, physicist formerly with the ESA.
• MH suggests Pantelis Koutroumpis, The Productivity Paradox, a report.

2. Background literature update.

• Https://gizmodo.com/the-last-images-from-doomed-space-probes-1847100494
• Some interesting videos are at the Kartik Gada channel such as  at https://www.youtube.com/channel/UCuRX67CJhaOT98Jdjh85CEQ which we discussed previously.
• For general reference here are some generic questions about articles (and videos):
  

What is the source?
What is the most significant advance in the human knowledge presented in the paper? 
Why is that advance important?
What important questions arise from the paper for future research?
What important questions would it be nice if the paper answered, but does not answer? 
What does the paper present that is novel (no one else has provided that before)? 
What is the relevance of the paper to our satellite research goals?
Questions from the group?
