Isn't it easier to launch new satellites.
scheme271•1h ago
Probably not, launch costs are still a few thousand to tens of thousands per kg so launching a 500kg jetpack vs a 5000kg satellite is pretty substantial.
manquer•52m ago
Easier yes cheaper no, these satellites are in GEO.

Cost of per kilo to GEO is high. That is not going to change by enough even post starship level of 2 stage resuse - as GEO launches would need a third kicker stage as the second stage will not go so high to be reusable.

Also nobody wants to clutter GEO with many new sats. There are limited slots and dead satellites need to move graveyard orbits and cannot be de orbited[1]. The slots + frequencies are so limited that small pacific country of Tonga[2] makes millions every year renting this out.

Every final stage/booster that launched a GEO satellite is also in orbit now. Including the stage that launched this mission.

All this method basically reduces launched orbital objects from two (stage + sat) to just stage. The new sat/repair unit just attaches to older satellite .

---

[1]In reasonable time frame that is, unlike in LEO, GEO reentry times can range between hundreds to thousands of years

[2] Due to quirk of international law they have rights to it. Like IP address allocation it was basically first come first serve for countries and one guy figured he coule exploit the loophole via small sovereign country .
