Sun square Mars (orb 4.3°) creates concrete friction between the two planets. The orb is moderate; it stays secondary beside tighter signatures.
Here, Sun in Aquarius in House 10 brings identity, ego, father figure, visibility, and direction into House 10 (vocation, status, responsibility, and public image), with Aquarius style (independence, networks, distance, and collective change); Mars in Libra in House 6 brings action, courage, competition, and effort into House 6 (daily work, technique, and bodily discipline), with Libra style (relationship, balance, negotiation, and sense of form).
Concrete friction: this aspect creates visible tension between ego, father image, and action: will can feel attacked, blocked, or forced to prove strength, sometimes through a weak, absent, inhibiting, or castrating father image. Visible angle: Sun near the Midheaven (orb 2.9°) touches an angle; this aspect is easier to notice through social role, reputation, career, and public image. House 10 (vocation, status, responsibility, and public image) is in friction with House 6 (daily work, technique, and bodily discipline); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
