  • VB thesis status.
  • MH thesis status.
  • Paper based on VB thesis? If so what is the message of the paper? VB leaves on Dec. 26  until late January. RS suggests targeting WMSCI for the paper. He would like the thesis with the figures de-colorized, and would like the 4 excel data files labeled with independent and dependent columns.
Option A: Simply condense VB's thesis into a paper

Option B: Add some statistical analyses to VB's thesis figures for paper.

Option C: Build a paper based on the following outline:

Here are the key questions we could address in the paper, based in
part on what VB has found out in his thesis.

1) To what extent does it matter whether you measure lifespan in
years, in months, or in days? He has graphs showing curves based on
each of those time granularities.

2) What is the difference, if any, between
(i) measuring lifespan from launch date to SATCAT Status Date, and
(ii) measuring lifespan from launch date to death date (which we got
directly from McDowell as unpublished data).

3) What is the difference between measuring
(i) lifespan vs. launch date,
(ii) lifespan vs. SATCAT Status Date, and

(iii) lifespan vs. death date?

4) VB has some graphs that preliminarily address the question of
lifespans of US satellites vs. lifespans of Soviet satellites. This is
an extension of the article we just published.

5) If we apply error bounds to the curves in the just-published
article in The Space Review, does it strengthen the conclusion (USSR
started ahead but US improved faster) or muddy the waters?

Perhaps not all of these questions are addressable with the error bounds
RS proposes to apply. I don't know. I am interested to hear
thoughts on where to go next with this problem statement.
