9995 Alouette           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
The first Canadian satellite Alouette-1 was launched on 1962 Sept. 29. It was engaged in research and exploration of the upper atmosphere, especially the ionosphere. During its six-year lifespan it returned the first useful data on the ionosphere. The citation was prepared by W. Fröger.
