Thruster pack
From Tardis Wiki, the free Doctor Who reference
Thruster packs were thruster units used by individuals for maneuvering in space. They were utilised by the World Space Patrol in the 2060s.
In January 2065, Steve Zodiac wore a thruster pack to travel from Fireball XL5 to an adrift space freighter in order to investigate. Later, after Steve had been put into a "frozen sleep" and thrown from the freighter by the Batmen, Doctor Venus and Professor Matic donned thruster packs to retrieve his body. (COMIC: The Batmen)
