Abstract: A capturing plate is attached to an on-orbit device, and the capturing plate is attached to a part of the on-orbit device where a capturing device bonds to the on-orbit device in space with a bonding component, including adhesive, of the capturing device. A method for capturing the on-orbit device includes moving the capturing device including the bonding component to the on-orbit device and letting the bonding component of the capturing device adhere to the on-orbit device.

Abstract: A space device includes: an adhesion part to adhere to a target existing in the space; and a propulsion part to obtain propulsion power. The space device that adheres to the target at the adhesion part moves together with the target by the propulsion part, thereby conveying the target to a predetermined target position.

Abstract: Simplify, downsize and reduce power of devices which comprise the satellite navigation system used in approach and docking in space. The navigation system 1 which estimates an attitude of a target object T in space comprises: an optical marker 10 that is attached to the target T and reflects light; a lighting device 20 that irradiates the target object T with light of a predetermined wavelength band; an image acquisition device 30 that acquires an image of the optical marker 10 which has reflected the light of the predetermined wavelength band; and an image processing device 40 that processes the image acquired by the image acquisition device 30 and thereby estimates the attitude of the target object T. The lighting device 20 and the image processing device 30 are loaded on an aerospace vehicle 2.

Abstract: A rotation suppressing device 1 includes: a body 10; a shaft 20 extending outward from the body 10 and configured to rotate about a first rotation axis A1; a rotation part 30 configured to rotate about a second rotation axis A2 together with the shaft 20; a capture part 40 fixed to the rotation part 30 and configured to capture space debris D; a braking part 50 configured to suppress rotation of the shaft 20; and a body rotation suppressing part 60 configured to suppress rotation of the body 10 occurring when the braking part 50 operates.
