Kusnirák and P. Pravec at Ondrejov. Antonín Vítek (b. 1940), a Czech biochemist and computer specialist, became an enthusiastic space popularizer in the Czech media. He disseminates accurate and reliable news and commentaries of cosmonautics in innumerable articles, books, interviews and talk-shows.
