Robotic Spacecraft Service Vehicles
- MDA Space Infrastructure Servicing vehicle — an in-space refueling depot and service spacecraft for communication satellites in geosynchronous orbit. Launch planned for 2015.
- Mission Extension Vehicle is an alternative approach that does not utilize in-space RCS fuel transfer. Rather, it would connect to the target satellite in the same way as MDA SIS, and then use "its own thrusters to supply attitude control for the target."

Famous quotes containing the words service and/or vehicles:
“We could not help being struck by the seeming, though innocent, indifference of Nature to these men’s necessities, while elsewhere she was equally serving others. Like a true benefactress, the secret of her service is unchangeableness. Thus is the busiest merchant, though within sight of his Lowell, put to pilgrim’s shifts, and soon comes to staff and scrip and scallop-shell.”
—Henry David Thoreau (1817–1862)
“Television programming for children need not be saccharine or insipid in order to give to violence its proper balance in the scheme of things.... But as an endless diet for the sake of excitement and sensation in stories whose plots are vehicles for killing and torture and little more, it is not healthy for young children. Unfamiliar as yet with the full story of human response, they are being misled when they are offered perversion before they have fully learned what is sound.”
—Dorothy H. Cohen (20th century)
