Prepared testimony of NASA witnesses
before the Subcommittee on Space of the Committee
on Science, Space, and Technology; March 24, 1993.

1991 and 1994 statements from the
House Committee on Science and Technology: “The
chances of the Earth being struck by a large asteroid
are extremely small, but since the consequences

of the threat and prepare to deal with it. We
have the technology to detect such asteroids and
to prevent their collision with the Earth…”
