In this work we investigate the possibility of two-stream instability in theVenusian atmosphere to lead to momentum transfer to subsequent escape ofHydrogen and Oxygen ions from the ionosphere. We employ the hydrodynamic modeland obtain the linear dispersion relation from which the two-stream instabilityis studied. Further the interaction of solar wind with the ions of Venusionosphere from which the instability sets in, has been studied with the datafrom ASPERA-4 of Venus Express (VEX). The data supports the fact that thetwo-stream instability can provide sufficient energy to accelerate ions toescape velocity of the planet.
