Mars square Lilith (orb 5.1°) creates concrete friction between the two planets. The orb is moderate; it stays secondary beside tighter signatures.
Here, Mars in Scorpio in House 12 brings action, courage, competition, and effort into House 12 (retreat, contemplation, long time, and possible confinement), with Scorpio style (intensity, desire, crisis, secrecy, and invisible power); Lilith in Leo in House 9 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 9 (vision, belief, study, and wider horizons), with Leo style (presence, pride, creation, and the wish to be seen).
Concrete friction: this aspect creates tension between anger, desire, action, impossible ideal, and refusal to yield. Visible angle: Mars near the Rising sign (orb 1.2°) and Lilith near the Midheaven (orb 4.5°) touch angles; this aspect is easier to notice through first impression, body language, reflexes, and entry style; also through social role, reputation, career, and public image. House 12 (retreat, contemplation, long time, and possible confinement) is in friction with House 9 (vision, belief, study, and wider horizons); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
