A space station ( orbital station)
A spacecraft capable of supporting a crew, which is designed to remain in space (most commonly in low Earth orbit) for an extended period of time and for other spacecraft to dock.
It lacks of major propulsion or landing systems.

Most of the food on board is vacuum sealed in plastic bags.
Cans are too heavy and expensive to transport, so there are not as many.
More spices are used than in regular cooking, and the crew looks
forward to the arrival of any ships from Earth, as they bring fresh fruit
and vegetables with them.

WELCOME TO:ROBOTS IN SPACE
A robot may be defined as a self-controlled
device consisting of electronic, electrical,or mechanical units.
They never get tired; They can endure physical conditions that are
uncomfortable or even dangerous; They can operate in airless conditions; They do not get bored by repetition; They cannot be distracted from the task at hand.
Types of Robots in Space ROV (Remotely Operated Vehicle)
• ROVs are used in nuclear facilities for inspection and repair in areas too dangerous for humans, and by police bomb squads for removal of potentially hazardous materials.
An ROV can be• an unmanned spacecraft that remains in flight,• a lander that makes contact with an extraterrestrial body
and operates from a stationary position,• a rover that can move over terrain once it has landed
Future Robots in Space
Servicers are humansized, multi-arm, remotemanipulators which are used for
servicing and assembly.
Cranes, like the RMS currently operated on Space Shuttlemissions, are long single arms usedfor repositioning larges masses.
Rovers are mobile platforms for transporting payloads on planetary servicers andextraterrestrial surfaces.
Today's space robots operate either by teleoperation (continuous remote control of a manipulator) robotics (preprogrammed control of a manipulator).
Both are controlled by humans. The distinction is that the
teleoperators are controlled by humans remote in distance, and robots are controlled by humans in time (by way of computer programs).
A robotic spacecraftis a spacecraftwith no humans on board, usually undertelerobotic control.
Space Elevator
A space elevator is a proposed type of
space transportation system.
Its main component is a ribbon-like cable (also called a tether) anchored to the surface and extending into space.
It is designed to permit vehicle transport along the cable from a planetary surface, such as the Earth's, directly into space or orbit, without the use of large rockets.
