The authors announce the conjecture that a family of $K3$ surfaces the Artin height of whose generic fiber is greater than $2$ does not degenerate; they prove this conjecture for surfaces of degree $2$. As a corollary it is shown that a family of supersingular $K3$ surfaces does not degenerate; i.e., its variety of moduli is complete. Bibliography: 18 titles.
