Kerbonauts! Your #KSP2WeeklyChallenge is.... Complete the Jool 5!
Primary goal: Launch a single-Kerbaled mission (only 1 spacecraft may depart Kerbin's SOI, but it can be built in Kerbin orbit) that passes through the SOI of all 5 of Jool's moons at least once before returning to Kerbin
Secondary goal: Same as primary, but land a probe on each of Jool's moons (the probes don't have to return)
Jeb-level goal: Same as secondary, but plant flags on Bop and Pol
Val-level goal: Plant flags on all 5 moons of Jool in one mission before returning safely to Kerbin
