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)
|

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?)
