The discovery of dark matter (DM) by Zwicky (1933) remains inconsistent within known physics. Astonishingly, a number of solar system observables exhibit unexpected “planetary dependencies”, even though no remote force beyond gravity exists. Question: Are persisting local mysteries also signals from the dark sector? Gravitational focusing of DM streams has short focal ranges since the impact goes with 1/(speed)2. Also, the inner mass distribution of solar system bodies acts as a gravitational lens, with amplification of streams being up to ~109, compared to few % for isotropic DM. The analysis of a number of observations within the solar system fits in the streaming DM scenario following gravitational lensing effects by solar system bodies. More specifically, analyzing secondaries from cosmic rays (CRs) points to streaming DM with the secondaries coming from the parent massive DM due to their self-annihilation, decay or interaction with ordinary matter. The secondaries provide the time stamp of the DM. New direct measurements of more CRs species can strengthen this result. All CR telescopes may have taken relevant data worth re-analyzing; the same applies to the data from direct DM searches. This is because only streaming DM can result occasionally in otherwise anomalous “planetary dependencies”. This is a new opportunity to unravel DM signatures hidden in existing data. This proposal is model-independent. So far the direct DM searches expect an annual distribution, while the underlying noise usually has a seasonal variation. In this proposal we overcome this noise problem by projecting the measured events (signal and noise), e.g., instead of on365 days, on the 88 and 225 days of the orbital periodicity of Mercury and Venus, respectively. So far the DM Axionantiquarknugget model by ZHITNITSKY is the inspiring favourite, while this approach is open to any other DM model.
