. Alouette 1 remains in orbit and some suggest there is a slim chance it might turn on if the right signals were transmitted. In 1966, it was estimated that Alouette 1 would remain in orbit for 1000 years.

Duplicate construction

Two satellites were built for redundancy in case of a malfunction; if the first unit failed, the second could be launched with only a couple of months delay. It took 3½ years after Alouettes proposal to have it developed and built. The satellites S27-2 (prototype), S27-3 (which became the launched satellite), and S27-4 (which became the backup) were assembled by Defense Telecommunications Establishment Electronics Lab in Ottawa
