Just as barges and oil platforms need tug boats to get into position, space stations and satellites will need space tugs to pull them into their desired orbit. The Worker Bee is comprised of an omnivore thruster which uses water as propellant and is powered by two inflatable reflectors. Trans Astra's Worker Bee will be able to provide transport for NASA astronauts, commercial satellites, and even tourists. 

APIS

APIS (Asteroid Provided In-situ Supplies) is a family of flight systems based on a similar architecture, ranging in size from the experimental Mini-bee, a 250kg technology demonstration spacecraft, through the Honey Bee, capable of capturing a 10m asteroid and extracting its resources, to the Queen Bee, capable of capturing a 40m asteroid for resource extraction. All use an asteroid containment system similar to that proposed for the original Asteroid Redirect Mission, optical mining for resource extraction, and a water based Omnivore Thrustersystem for propulsion. A variant called the Worker Bee, can serve as an orbital transfer vehicle, transporting items to high Earth orbits and beyond, potentially even to Mars.

In order to effectively mine asteroids, Trans Astra have created the Honey Bee. The Honey Bee is capable of maneuvering to a water rich asteroid, capturing the asteroid in its bag, and mining the asteroid using optical mining technology. The water extracted from the asteroid is stored in cryobags as ice to be transported to fuel depots. The Honey Bee also contains an Omnivore Thruster, allowing it to use the water it mines as propellant for its return journey.
