USING NRHO INVARIANT FUNNELS TO TARGET ENCELADUS SOUTH POLE

The south pole of Enceladus is a particularly interesting location in the search for life, due to the large geysers spouting from large cracks in the crust, known as ”tiger stripes.” Near rectilinear halo orbits (NRHO’s) are an attractive solution to position a spacecraft near the south pole. This work illustrates how to use invariant funnels to target NRHO periapses from resonant orbits and describes a catalog that can be used by mission designers to determine total ΔV budgets from various resonances.
