Propulsion strengthening member

Abstract

A propulsion strengthening member attached to a surface of an object existing in outer space, the propulsion strengthening member includes: a transparent member that transmits an emitted laser; and an opaque member that is provided between the transparent member and the object and absorbs the laser such that at least a part thereof is evaporated by energy of the laser.

1 . A propulsion strengthening member attached to a surface of an object existing in outer space, the propulsion strengthening member comprising:
 a transparent member that transmits an emitted laser; and   an opaque member that is provided between the transparent member and the object and absorbs the laser such that at least a part thereof is evaporated by energy of the laser.   
     
     
         2 . The propulsion strengthening member according to  claim 1 , wherein at least one transparent member and at least one opaque member are stacked alternately. 
     
     
         3 . The propulsion strengthening member according to  claim 1 , wherein a plurality of the transparent members are provided in the opaque member. 
     
     
         4 . The propulsion strengthening member according to  claim 1 , wherein the transparent member is a sheet-form member. 
     
     
         5 . The propulsion strengthening member according to  claim 1 , wherein the transparent member is a spherical member. 
     
     
         6 . The propulsion strengthening member according to  claim 1 , wherein the transparent member is formed from fluororesin. 
     
     
         7 . The propulsion strengthening member according to  claim 1 , further comprising a protective member provided on at least one face on surfaces of the propulsion strengthening member. 
     
     
         8 . The propulsion strengthening member according to  claim 7 , wherein the protective member has a light-blocking property for blocking sunlight. 
     
     
         9 . The propulsion strengthening member according to  claim 7 , wherein the protective member is resistant to atomic oxygen. 
     
     
         10 . The propulsion strengthening member according to  claim 9 , wherein at least a part of the protective member is formed from fluororesin. 
     
     
         11 . The propulsion strengthening member according to  claim 1 , wherein a symbol for identifying the propulsion strengthening member is applied to the surface of the propulsion strengthening member.
