^The ten entries that are numbered indicate the instances of successful indigenous orbital launch capability development.
^The ten countries and successor states/union indicated in bold (and numbered) retain orbital launch capability.
^ abcdRussia, took over the Soviet space program after the Soviet Union's dissolution with Ukraine inheriting a smaller part of the Soviet space program's space launcher and satellite capability. Russia and Ukraine inherited space launcher and satellite capability from the Soviet Union as successor states.
^United States also has private companies capable of space launch
^ abcFrance launched its first satellite by its own rocket from Algeria, which had been a French territory when the spaceport was built but had achieved independence before the satellite launch. Later France provided a spaceport for ESA space launchers in French Guyana, transferring its capability to ESA as a founding member.
^UK only self-launched a single satellite and that from a commonwealth (Australian) spaceport. Later it joined the ESA, but not the launcher consortium Arianespace, therefore becoming the only nation that developed launch capability and then officially lost it.
^Ukraine provides its own space launcher to Russia and does not use its own space launcher to put satellites in orbit (first Ukrainian satellite is Sich-1 launched on August 31, 1995 by Ukrainian Tsyklon-3 from Plesetsk Cosmodrome in Russia).
^The North Korean government first claimed a successful launch in August 1998 with Kwangmyŏngsŏng-1, which was internationally determined to be a failure. The government retracted this claim only after the launch of Kwangmyŏngsŏng-3 Unit 2.
