🔭 Space Simulator: Observatory Balcony, Telescope, Kepler Orbits, Tasks and Needs Lab

A balcony observatory game: aim a telescope at planets, the Moon and galaxies placed by a Kepler ephemeris, plan Hohmann transfers, build planetary systems and finish daily tasks that raise your skills, coins and level; numerical self-checks verify Kepler III, the leapfrog integrator and the delta-v figures.
