LEO Space Debris

For SpaceNut ...

Where should this go?

https://www.yahoo.com/news/finders-keep … 52906.html

Under House Bill 221, someone who locates debris “reasonably identifiable as a spaceflight asset must report the description and location” to their local police.

The bill defines a “spaceflight asset” to include “crewed and uncrewed capsules, launch vehicles, parachutes and other landing aids, and any ancillary equipment that was attached to the launch vehicle during launch, orbit, or reentry.”

Once contacted, the police must then make a “reasonable effort” to identify the owner of the part and “promptly” notify them. The bill allows the owner to enter private property to recover the part if police believe “exigent circumstances” exist: whether the part presents “an immediate danger to public safety” or if there’s a danger the part will be damaged or destroyed.

Someone who finds the part can’t keep it, sell it or refuse to turn it over to police. If they do, they could be charged with a new misdemeanor: “misappropriation of a spaceflight asset.”

Re: LEO Space Debris

This is no different than if you have to make an emergency landing in a farmer's field.  The farmer doesn't get to keep your plane.  If SpaceX accidentally lands a Dragon on my house, then I'm going to ask for repairs, but their Dragon is still their property and my home is still my property.  They're not entitled to keep parts of my home and I'm not entitled to keep parts of their Dragon.  That seems pretty fair to me.

Re: LEO Space Debris

There are only the ownership of the identified objects parts of which there is no enforcement to clean it up after its been created by that owner.
The has been a couple of attempts to net them and such but these parts will always be there....
Most will burn up long before they do harm to man or ship while in orbit but as the density increases so will the odds of a hit...

Re: LEO Space Debris

Its still working but we have already had a few close calls with stuff that we did identify early enough to get out of its way but for how long can we keep it up?

What if the new chinese station got dinged and it was destroyed one would think that they would point fingers as well as to whom caused what to happen... So its about time to change the space debris rules and get serious about cleaning it up....

Re: LEO Space Debris

excellant post for this topic as well

Rather than deploying thousands upon thousands of tiny satellites, I wonder if SpaceX would be better served by deploying a smaller number of more capable but longer-lived and lower cost satellites that they maintain in orbit through successive hardware upgrades as better commercial hardware becomes available.  If they really can launch for $2M per flight using Starship, then the cost of "space rated" satellite hardware could be brought down to commercial levels.  They'll always have rockets ready to launch, so they can replace that hardware in orbit, at-will.

A heavier but more durable steel chassis to adequately shield commodity silicon from GCR / SPE / CME could drastically improve throughput for minimal cost.  For example, Apple's M1 chips could be used for high speed internet, telecommunications, weather, and mapping.  Their chips are cheaper than the purpose-built rad-hard chips typically found in satellites, and available by the millions.  Replaceable thin film solar arrays, similar to what NASA is deploying aboard ISS, AF-M315E mono-propellant to avoid Hydrazine-related issues, and Tesla Lithium-ion batteries would round out the commercial hardware approach.  When the old hardware becomes obsolete, a Starship could deliver a small crew to upgrade the satellite's electronics / batteries / solar panels and return the old hardware to Earth for recycling.

Right now, there's a veritable cloud of thousands of satellites, most of which are no longer operational.  To avoid creating an impassable debris field in orbit around the Earth, perhaps as Starship comes online, it's time to consider cleanup so that when a fleet of ships is ready for Mars colonization, there is less risk of collision with thousands of small but still dangerous satellites zipping around up there.  Satellite cleanup and repair is also another potential source of revenue for SpaceX that can produce immediate return on investment.

This brings up robust not just cheap

Re: LEO Space Debris

Even the moon and mars we will need to do a better job of not creating the debris which is now becoming hazardous to man and machine.
