- VK suggested as a measure, for each year, launches*averageLifeSpan.
- DB suggested lifespan/mass as a figure for each satellite, to be graphed as an average for each year, because cubesats may have lower mass, but lower lifespan, and still be an advance in technology. Thus lifespan alone might stop working pretty soon. We might not have mass data available for satellites (though we could do it for extraterrestrial spacecraft).
- New satellite data from planet4589. Merge with SATCAT and mine. VB is working on it.
- An analysis of lifespan trends on a per-country basis or per-organization basis would be interesting (MH suggested finding out to what extent the variation in satellite lifespan might be caused by new space programs). Same with lifespans and perigees.
- What if we analyze only SATCAT reentry status dates, and compare with the present analysis of all statuses except "in orbit." Probably would make little difference, but should compare to test this.

2. AAS-2019. JAAS submissions due March 27, 2019. The annual meeting this year is at Hendrix. MH is presenting and submitting. DB found that Wright's law predicts a 100 year lifespan after 3,424,684 satellites die. This could be included, if not for this paper then for a future one.
3. Teaching track. DB used the google sheet to illustrate operator precedence in class. RS teaches engineering stat and may have some use for the trend and envelope analyses he's done on the data. These could be used for a future publication as well.
4. NEO/NEA analysis track: VK has some preliminary reports. What are the prospects?
5. It would be interesting to check lifespan/mass over time for deep space craft to see if it is an improvement over lifespan alone.
6. Deep space exploration: we still need to do an analysis of missions/craft on a per-craft rather than per-year basis. In fact, a per-year analysis is still needed for international missions.
7. HA suggests discussing on 3/29 the following articles:

- Sizing down and reaching higher with CubeSats by Jeffrey Manher & Kirk Woellert. link: https://room.eu.com/article/Si
zing_down_and_reaching_higher_ with_CubeSats. Keywords : Moore's Law, Space Exploration. Summary: Industry revolutions, the chore of technology has started quietly. The year window between 1950 and 1960 was when space exploration depended on rockets and huge satellites. This paper explained how the miniaturization of electronics ( technology in general, referring to Moore's Law) has continued to evolve but without affecting too much space exploration that has continued to its try and succeed/fail methods through space missions. Moore's law was the center of the study. - Big or Small - aerospace innovates through constraint, link: https://room.eu.com/article/bi
