This would effectively lower the maximum altitude for a spacecraft without propulsion to <500km, probably lower (depending on geometry/density). It’s probably a good thing overall, but it does force a lot of small satellite makers (including students) to either restrict themselves to a small number of launch opportunities or add propulsion. It might be nice to have a more lax rule (like 10-15 years) for small non-profit launches.
- chris_va 4y agoPropulsion isn't as bad as it used to be, and there is a real risk >500km with the 10,000 satellites going up... I would prefer a standardized airbag (or similar) that autodeploys at EoL to increase the surface area, though.
- marsokod 4y agoPart of the discussion on the drag sails was that while they are decreasing the time in orbit, they are increasing the collision area and therefore the general risk of collision remains the same. Tethers are somewhat better but hard to work with. Propulsion is the best bet at the moment. One consequence of this ruling could also be in the orbit insertion strategy. Currently agencies are not too worried about your satellite being in working condition in orbit as long as you demonstrate the risk of collision is low enough through natural means. Now that we are likely required to use active deorbiting system (and possibly active collision avoidance), the rules may be more tightened regarding testing and analysis.
