Space Debris Problem (3 videos, NASA and OG papers)

---

Video #1 - This video broadly describes the space debris problem.

Video #2 - This short video describes how polluted the space environment has become and demonstrates the population of debris at various sizes.  Keep in mind, that a 1 cm debris object, at 7.5 km/sec, packs enough energy equal to a hand grenade.  Image that going off inside your refrigerator.

Video #3 - Real world case study details for large satellite operator:

• A publicly traded satellite communications operator tragically suffered what experts think may be a debris collision
• The uninsured satellite sprung a propellant leak, which shortened its life 15 years
• As a result, investor revenue went down $678M across 2Q19 & 3Q19, cost $382M to replace satellite, and caused a $200M sales backlog reduction.  Total service restoration cost =  $1.06 billion.  Ouch!
