 Payloads may contain extremophiles for diverse environments and cyanobacteria similar to early microorganisms.Hardy multicellular organisms (rotifer cysts) may be included to induce higher evolution.The probability of hitting the target zone can be calculated from formula_1 where "A"(target) is the cross-section of the target area, "dy" is the positional uncertainty at arrival; "a" – constant (depending on units), "r"(target) is the radius of the target area; "v" the velocity of the probe; (tp) the targeting precision (arcsec/yr); and "d" the distance to the target, guided by high-resolution astrometry of 1×10−5 arcsec/yr (all units in SIU).
