12/14/18: Threads again, plus new graphs

1. Spacecraft mass has been graphed. 
   
   
   
   
2. EPSCoR application due Jan. 9(?). DB to find out about desired amounts, time spans, collaborations across campus, unfunded out-of-state collaboration. This may be a new proposal, but either way, see arnasaepscor.host.ualr.edu/epscor.html for background.
3. The Space Review track. DB needs to write it. It is short. It could include VK's latest satellite figures relating lifetimes vs. end dates. These may be ready to use. Recall that minitab does not readily curve fit or regress arbitrary function types, leaving open the question of how to regress to a power law curve like Wright's law.
4. 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. For example what about the graphs above (mass vs. time)?
5. Former OAS paper revisions track. Recall on 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. Another possibility is to include non-VK graphs like the graphs above (mass vs. time).
6. 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. Some relevant background reading 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.
7. Teaching track. DB used the google sheet to illustrate operator precedence in class. RS is teaching engineering stat next semester and may have some use for statistical analyses of our data as examples.
8. Literature review track. Need to organize our notes and citations into one resource. See the blog tab "READING LIST AND OTHER RESOURCES"

Discussions about the below are postponed for now.

1. A possible IEEE Aerospace Conference 2020 track (DB). It's far away (Montana in 2019) so travel is an issue in addition to delay.
2. 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 is interested and will likely have some results in time to do it.
3. NEO/NEA analysis track. More analyses later.

12/7/18: Slightly trimmed list of project threads

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. 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.
4. 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.
5. 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?)
6. Literature review track. Need to organize our notes and citations into one resource.
