The outer shell has variable mass, and this combined with a modification of the Defence Force Field Prisms allows a TARDIS to hover or float. Using short bursts of power, a TARDIS is capable of generating kinetic movement. While in hover mode the console will generate a humming noise. Putting the TARDIS in Hover Mode makes it easier to use the Manual Override controls to navigate.
A TARDIS can be set to fly in space. If no one is at the controls a TARDIS will automatically lock on to the nearest gravitational source and travel to its surface. It is possible to manoeuvre in a zero gravity environment and put a TARDIS into a spin. The acceleration is at least 9.8 meters per second squared (allowing it to hover on a G-Type world) or travel through space. It can compensate for 28 kilometre per hour winds and reach speeds of at least 100 kilometres per hour. Its maximum speed in a Type G atmosphere is about 50% faster then most 21st century cars (so about 300 kilometres per hour). With great difficulty, an operator can use a TARDIS to parallel or pursue a moving ground vehicle. It is even possible to clumsily dodge intervening obstacles.
A TARDIS can be put in a Parking Orbit above a planet before materializing on its surface. It is also equipped with Vworp Drive for long distance travel through real space. In this mode it can escape from the gravitational field of a black hole at distances that even vessels of the year 2500 AD can't escape from. Caution should be taken, as the response time of the inertial dampener will be sluggish if Vworp Drive hasn't been used recently.
