A relationship between wetting contact angle and gravity was investigatied. Lowered and increased (up to 22g) gravitation conditions were simulated in terrestrial conditions. Various «solid — liquid» systems were considered for both low temperature liquids (water, glycerin) and metal melts (tin, gold). It was found that the gravitation level does not influence on the contact angle of wetting solids by liquids.
