Height of capillary rise liquid is given by h = 2T/(rρg) . T is surface tension, r is radius of capillary tube, ρ is density and g is acceleration due to gravity.
 
Since acceleration due to gravity is in denominator and acceleration due to gravity is negligibly small at the orbit where satteleite is revolving around the earth, capillary rise will be very high. So 'full length' may be the correct answer
