Each spacecraft carried two active and one spare 100 W. 14/12 GHz transponders. Built by EUROwith assistance from ASR, the BS-2 series satellites were designed for five years of operation.

Famous quotes containing the words early and/or models:
“Perhaps the most valuable result of all education is the ability to make yourself do the thing you have to do, when it ought to be done, whether you like it or not; it is the first lesson that ought to be learned; and however early a man’s training begins, its probably the last lesson that he learns thoroughly.”
—Thomas Henry Huxley (1825–95)
“The greatest and truest models for all orators ... is Demosthenes. One who has not studied deeply and constantly all the great speeches of the great Athenian, is not prepared to speak in public. Only as the constant companion of Demosthenes, Burke, Fox, Canning and Webster, can we hope to become orators.”
—Woodrow Wilson (1856–1924)
