Design
The second of eight Intelsat III satellites to be launched, Intelsat III F-7 was built by TRW. It was a 647-kilogram (1,426 lb) spacecraft equipped with two transponders to be powered by body-mounted solar cells generating 183 watts of power.[3] It had a design life of five years and carried an SVM-2 apogee motor for propulsion.
Launch
Intelsat III F-7 was launched on the maiden flight of the Delta M rocket, flying from Launch Complex 17A at the Cape Canaveral Air Force Station.
gollark: Integrated tools are, in my experience, better able to deliver actual error messages.
gollark: It's not like tools being made from composing other tools makes them not complex.
gollark: Like I said, it can be done with external tools but the convenience is a feature here.
gollark: You can do extra things, like provide a certain capability set to some non-root processes (e.g. to allow network configuration without access to everything ever), or hide bits of the filesystem, or restrict networking, or restrict which users it can see, and such.
gollark: It doesn't actually have to.
