Intro

|

Why do we care
|
||||
|
||||
Possible stories:
|
||||
sep 2019
|
||||
2020 - 3 near misses with ISS (https://www.jpost.com/science/international-space-station-nearly-struck-by-chinese-satellite-debris-684809) (https://orbitaldebris.jsc.nasa.gov/quarterly-news/pdfs/odqnv24i3.pdf)
|
||||
May 2020 - Fregat tank breakup (left debris from 1000 to 6000 miles in altitude)
|
||||
May 2021 - Canadarm2 got hit (https://www.asc-csa.gc.ca/eng/iss/news.asp, part way down)
|
||||
Nov 2021 - Dodge debris from anti-satellite test in 2007 (China) (Jerusalem post above)
|
||||
Nasa releases a

|
||||
Why should we care?
|
||||
- All orbits are subject to some degree of polution.
|
||||
- Common uses: GPS, Military Communications, Commercial internet and TV.
|
||||
- Exploratory uses: R&D of pharmaceuticals, exploration.
|
||||
- Collisions and debris damage are to some degree inevitable.
|
||||
|
||||
What is different now:
|
||||
- Launch costs (https://aerospace.csis.org/data/space-launch-to-low-earth-orbit-how-much-does-it-cost/) (https://fortune.com/2017/06/17/spacex-launch-cost-competition/)
|
||||
- Cubesats/nanosats (numbers at https://www.nanosats.eu/)
|
||||
- in short, accessability. With lower cost per mass to orbit, more reasons to go. With lower development costs, easier to build many small satellites. This gives us a need for urgency.
|
||||
|
||||
|
||||
|
||||
major points
|
||||
- Summaries of results so far.
|
||||
- Request for suggestions on utility functions that might be worth investigating
|
||||
- Discussion of goals
|
||||
- Investigate pigouvian taxation, cleanup bonds, etc.
|
||||
- Standardize interface so it is easy to estimate results.
|
||||
-
|
||||
- Discussion of other work that should happen
|
||||
- Estimation of parameters (simulation, bayesian, calibration, best guesstimates, etc)
|
||||
- Rights of way work (way to get operators to declare a no-move value?)
