- tectonic 8y agoCubeSats are low mass and tend to be in low orbits that decay in time periods between a few weeks and 10 years. Also, all modern satellites have to be launched with a deorbit plan.
- pvarangot 8y agoI'm not sure the de-orbit plan thing is successfully being enforced by any launcher. That being said kessler's syndrome impact are usually over-exaggerated by "big space" as a reaction the disruption going on in the business.
- benj111 8y agoWell it says there are 600,000 pieces of space junk. But that's spread out over a large area. The area of the earth is 510million km2, so worst case (all on the same plane, at ground level) that's 850km2 for every item of 'junk'. I don't see that being sufficient density for a domino effect. I suppose it depends on how uniform the cloud density is.
- bagels 8y agoIt's not uniform at all. Most objects are in high inclination orbits, which means many intersect near the poles.
- ummonk 8y agoCube says are in rather low orbits and have a high surface area to mass ratio so they decay rather rapidly. Not really a big deal as far as space junk goes.
