Spaceship capacity to LEO >100,000 kg (wikipedia)
Cubesat max mass 1.33kg (wikipedia)
That comes out to 75k max mass cubesats.
Cubesat is (10cm)^3, 100 fit in 1m^3, 75k fit in 750m^3.
Starship pressurized cargo volume is 1000m^3 (plenty of space).
At $2M per launch, it comes out to $27 per cubesat.
- blackguardx 6y agoThe launch canisters that contain these cubesats are large and weigh more than the cubesat itself. They do that so they don’t jeopardize the main payload. But, if it was only cubesats, the launcher could probably be simplified.
- m4rtink 6y agoThe Starlink deployment system is preatty minimalistic (just a bunch of rods holding the stack of satellites together) so maybe something similar could be done for cubesats as well, possibly by making them a bit more sturdy at some extra added weight.
