The “cherry-picker”
Fellow spaceman Robert Lee “ Hoot ” Gibson snap a picture of McCandless carrying out another part of the military mission – try out the Remote Manipulator System ( RMS ) . “ What I did was I shifted the camera so that he was n’t ripe in the centre of the picture . I put him on the edge and the artificial satellite ’s rudder on the other edge of the picture . That made a really cool photo , Gibson said toNASA .
The RMS was contrive to allow astronauts to work on outside the quad vehicle but remain anchored via the Manipulator Foot Restraint , nicknamed the cherry tree . Pictured here with McCandless , the restraint feature a pocket-sized platform that could allow whoever was work from it to pack out natural action such as satelliterepair .
