11/16&23&30/18: Followup on the many threads identified in preceding (b)log entry

1. The Space Review track. DB needs to write it. It is short. It could include one of VK's satellite figures, the one on lifetimes vs. end dates. This figure (currently fig. 3) has unexplained dips. These might be noise but we don't really know yet. He could update the graph by including the number of data items whose average forms each year's data point in the graph. We might also need to manually look at the cleaned data to see if something jumps out upon inspection. The graph looks like it is leveling off (on a log plot) which would not be exponential increase. RS noted that the statistical package he is most familiar with does not curve fit arbitrary function types, leaving open the question of how to do regression to a power law curve (i.e., Wright's law).
2. A possible regular academic journal track (RS). WMSCI is a possibility. DB should figure out what figures will not be in the article for The Space Review so RS can use them in another paper. 
3. A possible IEEE Aerospace Conference 2020 track (DB). It's far away (Montana in 2019) so travel is an issue in addition to delay.
4. A possible CCSC Mid-South track. Conference is April 12th and 13th, 2019, at UA in LR. There is a journal pub for accepted papers. www.ccsc-ms.org. Deadline for submissions is Monday, Dec 17, 2018. No one seems to want to take the lead on this so it's probably off the list of activities.
5. Annual ASGC Symposium track. May be 3rd Friday in April at Winthrop Rockefeller Institute. A good opportunity for a student to present a poster. MH may be interested and may have some results in time to do it.
6. Former OAS paper revisions track. HA plans to bring up some reviewer comment for discussion each time. 11/23/18: We discussed the reviewer comment that the graphs seemed not significant enough. HA plans to look through VK's graphs (in thesis, NEO document, NEA document, and satellite document) in order to identify ones that have more interest and are not already used in the AAS paper, and we can discuss more next time.

• 7. Satellite (planet4589.org analysis) track. The raw data is at https://planet4589.org/space/log/satcat.txt and column descriptions are at https://www.planet4589.org/space/log/satcat.html. The discussion on 11/23/18 focused on the need to better understand figure 3, as well as debugging figure 5b. Some interesting background reading on the topic is at http://www.spaceworkscommercial.com/wp-content/uploads/2018/01/SpaceWorks_Spacecraft_Mass_Trends_2014.pdf and http://www.spaceworkscommercial.com/#services which we could discuss.
• 8. NEO/NEA analysis track. More analyses later.
• 9. Teaching track. DB used the google sheet to illustrate operator precedence in class. (To discuss next time: possible to use some of our data to illustrate data analysis or statistical analysis as demos or HW problems?)

11/9/18: Numerous paths to future activities!

1. The Space Review track (DB).
2. A possible regular academic journal track (RS).
3. A possible IEEE Aerospace Conference 2020 track (DB). 
4. A possible CCSC Mid-South track. Conference is April 12th and 13th, 2019, at UA in LR. There is a journal pub for accepted papers. www.ccsc-ms.org. Deadline for submissions is Monday, Dec 17, 2018. DB is willing to have someone else lead on this track but is not able to schedule doing it himself.
5. Annual ASGC Symposium track. May be 3rd Friday in April at Winthrop Rockefeller Institute. A good opportunity for a student to present a poster. Maybe MH would be a possibility for this.
6. UALR EIT College Colloquium track. DB presented at it last Friday. The preparations raise certain technical issues. In particular we may need to fit a Wright's law curve, not an exponential Moore's law -

Wright's law may be (not 100% sure): 

Cost = 1 / (#manufactured^W), 0<W<1

or

1/TechnicalPerformance = 1 / (#manufactured^W), 0<W<1

• 7. MH suggested bringing up for discussion the idea of making data available publicly and having it user editable.
• 8. Former OAS paper revisions track. Report on the conference. HA has the opportunity to start working on a revised version based on reviewer #1's comments. For example, one comment could be addressed each week, discussed at the meeting, etc.
• 9. Satellite (planet4589.org analysis) track. What other kinds of duration analyses might be possible using data from planet4589? See https://planet4589.org/space/log/satcat.txt and https://www.planet4589.org/space/log/satcat.html. VK has two graphs of satellite lifetimes that seem to show exponential or Wright's law improvement. The graphs are based on satcat status date, which amounts to the end date of the satellite life.
• 10. NEO/NEA analysis track. Need to complete the analyses and figure out how to disseminate them. 
• 11. Teaching track.

11/2/18: Continuing threads

1. Moore's law track:

• DB would like to push forward with something for The Space Review. RS would like to ultimately target a regular academic journal. There is also the IEEE Aerospace Conference in 2020 to consider. So we would need to use care to avoid problematic overlaps in the material presented. 
• DB will present the college colloquium later this afternoon. Thanks for the plots and comments since last week's partial rehearsal.
• MH suggested bringing up for discussion the idea of making data available publicly and having it user editable.

2. NEO/NEA/planet4589.org analysis track:

• What other kinds of duration analyses might be possible using data from planet4589?

3. Former OAS paper track: HA has the opportunity to start working on a revised version based on reviewer #1's comments. For example, one comment could be addressed each week, discussed at the meeting, etc.
