61404 Ocenásek is a main belt asteroid. Its provisional designation was 2000 QM9 .
It was discovered on August 26, 2000 by P. Pravec and P. Kusnirák at Ondrejov.
The asteroid was named after Czech handyman Ludvík Ocenásek (1872-1949) who constructed a radial engine for airplanes and his own monoplane in 1905. He began systematic rocket research in 1928, and in 1930 his two-stage rockets reached an altitude of 1.5 km. He considered the launching of rockets from aircraft and the long-distance rocket delivery of mail.
