Hold on! The 555 and 566 are completely different parts, even if both have the same package (8 pin DIP) and power pins (8 and 1). The 566 is a voltage controllable oscillator while the 555 can be used as mono-flop or rate generator, depending on the external circuitry.

Fortunately a working Space Race, once it happens, will solve such kind of questions.
