Space anchors for use on the moon, mars and other extraterrestrial bodies

Abstract

A space anchor for use on an extraterrestrial body comprises at least one anchoring part connected by a connecting part to the driving part, wherein the driving part is designed for installing the anchoring part in the desired position in the soil and for connecting to an external structure on an extraterrestrial body. The anchoring part and the connecting part are manufactured with a polymer on a 3D/4D printer.

What is claimed is: 
     
         1 . A space anchor ( 1 ) for use or usable on an extraterrestrial body, comprising at least one anchoring part ( 2 ) connectable or connected by a connecting part ( 3 ) to a driving part ( 4 ) for installing the anchoring part ( 2 ) in the desired position in the soil of the extraterrestrial body and for connecting to an external structure, wherein the anchoring part ( 2 ) and the connecting part ( 3 ) are manufactured of a polymer. 
     
     
         2 . The space anchor according to  claim 1 , wherein the space anchor is a plate anchor, wherein the anchoring part is a plate ( 2 ) connected substantially perpendicular to the driving part ( 4 ) by the connecting part ( 3 ). 
     
     
         3 . The space anchor according to  claim 1 , wherein the space anchor is a screw anchor and the anchoring part ( 2 ) is at least a part of a helical screw connected permanently to the driving part ( 4 ) by the connecting part ( 3 ), wherein the anchoring part ( 2 ) and the connecting part ( 3 ) are manufactured as one piece. 
     
     
         4 . The space anchor according to  claim 1 , wherein the space anchor is a keying anchor comprising an essentially elongated anchoring part ( 2 ), having a leading end ( 5 ) and a trailing end ( 6 ), a longitudinal axis extending from the leading end ( 5 ) to the trailing end ( 6 ), a blind bore ( 7 ) extending there along the longitudinal axis from the trailing end ( 6 ) of the anchoring part ( 2 ), a through hole ( 8 ) provided on the connecting part ( 3 ), positioned substantially in the middle of the anchoring part ( 2 ) between the leading end ( 5 ) and the trailing end ( 6 ) and a sharp leading part ( 9 ) projecting from the leading end ( 5 ) of the anchoring part ( 2 ), the leading end ( 5 ) being formed as a tapering top, wherein the anchoring part ( 2 ) and the connecting part ( 3 ) are manufactured as one piece. 
     
     
         5 . The space anchor according to  claim 4 , wherein the anchoring part ( 2 ) is essentially flat. 
     
     
         6 . The space anchor according to  claim 4 , wherein the anchoring part ( 2 ), is essentially cylindrical. 
     
     
         7 . The space anchor according to  claim 1 , wherein the polymer includes a Polycarbonate (PC) or Nano-Polymers or Bio-Polymers or Nano-Bio Polymers or Nano-Bio Filaments or Bio-Filaments. 
     
     
         8 . A method of production of the space anchor according to  claim 1 , wherein the anchoring part ( 2 ) and the connecting part ( 3 ) is produced on a 3D/4D printer on an extraterrestrial body by using a polymer filament designed as a material for printing on the 3D/4D printer.
