chitownmike: beezeltown: This is cool. Satellite deorbiting devices will likely become a burgeoning part of the satellite industry.

At an estimated cost of $500 this isn't going to make anyone much money


Are you assuming that a system that costs the vendor $500 will be sold to the client for that same $500?

We know the answer to this.

I've long dreamt of a giant ball of oobleck used to capture and deorbit such space junk. I'd color it with green food coloring because why not?

ExYank: I don't see the market.

Designed for small sats without thrusters that orbit in the higher parts of LEO where there is still enough atmospheric drag to manipulate.

There are thousands of nano and cube sats deployed or being deployed that fit the bill. However, in LEO below 600 miles they do not need this device because drag will pull it down in 5 years. I can't recall any cube sats with periapsis more than 500 miles up but those extremely rare beasts are the only ones that might need it.

Generally speaking satellites going high enough up to need this will already have thrusters for demising and are too big for this to make much difference. Tiny satellites tend to get deployed in much lower (and cheaper) orbits where they don't need this.


The point per NASA's request for investigation was as a backup or last-ditch means to de-orbit a sat for the case where the thrusters run out of propellant or otherwise go kaput.

FTFA: "It should sell to a satellite builder for less than $10,000, according to Bevilacqua."

Well, I guess $500 is less than $10k.


Either there was an edit or I don't read to good. Meh

The first shot in WW3, if it comes from a...lower tech nation or individual group, will be to send a shirtload of ball bearings or scrap metal bits into orbit. This will trigger Kessler Syndrome and we can all say goodbye to satellite usage. Russia just tested the idea on a small scale.

It would be better to develop an armored satellite that can collect debris and then de-orbit the debris safely.

Another batch of those Starlink satellites are expected to launch from Cape Canaveral Space Force Station at 6:20 Wednesday night.

When did this become a thing?
