With the launch of Alouette 1, Canada became the third nation to have a satellite placed in Earth orbit, after the Soviet Union and the United States. Alouette 2 took part in a double launch with Explorer 31 and was placed in a similar orbit so that results from the two could be correlated. Alouette 2 was also the first mission in the ISIS (International Satellites for Ionospheric Studies) program conducted jointly by NASA and the Canadian Defense Research Board. Both Alouettes had a mass of 145 kg and were launched by Thor-Agena B rockets from Vandenberg Air Force Base.
