As a presentation, a few definitions and the basis for space mechanical autonomy are given. The principle contrasts among space and earthbound robots are featured, driven by the particular natural, framework, and automatic requirements of room missions. Some regular protests against the utilization of room mechanical technology are referenced and invalidated. A significant part portrays the run of the mill engineering, sub-frameworks, and some key advances of room robot frameworks, perceiving between the arm type and versatile robots (meanderers). The interdisciplinary framework character of room apply autonomy is accentuated. Next, the as of now saw application situations for space apply autonomy are presented: LEO applications for framework adjusting and payload tending, satellite overhauling in GEO, the gathering of enormous circling structures, and applications in investigation missions to the Moon, Mars, comets, space rocks, and other heavenly bodies
