"The pressure of Mars's atmosphere varies with the season, ranging from 6 to 10 millibars (1 millibar is approximately one one-thousandth of the air pressure at the surface of Earth)."
This would be considered vacuum by most people. It is the pressure found close to the 100km boundary which is considered to be outer space.
