Follow in the footsteps of the Voyager missions by visiting Jupiter, Saturn, Uranus, and Neptune using gravity assists. This is the ultimate test of mission planning and execution.
Enter a halo orbit around the Earth-Moon L2 Lagrange point. This three-dimensional orbit is challenging to establish but provides continuous line-of-sight to the lunar far side.
Use a low-energy transfer along the weak stability boundary to reach the Moon with minimal fuel. This advanced technique exploits three-body dynamics for extreme fuel efficiency.
Intercept a potentially hazardous asteroid and use a kinetic impactor to slightly alter its trajectory. Small changes now prevent Earth impact decades later. The fate of humanity depends on precision.
Undertake an epic 8-10 year journey to visit all four of the largest asteroids: Ceres, Vesta, Pallas, and Hygiea. This Grand Tour of the asteroid belt requires masterful trajectory planning, as Pallas' 34° inclination makes it particularly challenging to reach. Use asteroid gravity assists where possible to conserve fuel.
Use Titan's thick nitrogen atmosphere to gradually lower your orbit through repeated aerobraking passes. Each atmospheric pass removes orbital energy without using fuel, but fly too deep and you'll burn up. Achieve a stable science orbit around Saturn's largest moon using this advanced technique.
Tour all four Galilean moons while surviving Jupiter's brutal radiation belts. Visit volcanic Io, icy Europa with its subsurface ocean, massive Ganymede with its magnetic field, and ancient Callisto. Balance science objectives against cumulative radiation dose in this challenging multi-moon mission.
Venture into the Kuiper Belt to encounter Makemake, one of the five dwarf planets and a pristine remnant from the solar system's formation. At 45 AU from the Sun, this 12-15 year odyssey pushes the boundaries of human exploration. Multiple gravity assists are essential for this extreme mission.
Explore the scattered disk, the most distant populated region of the solar system. Perform a Grand Tour of multiple trans-Neptunian objects beyond 40 AU, including at least one encounter beyond 50 AU. This multi-year expedition maps the outer frontier of our planetary system.
Attempt one of the most difficult rendezvous missions possible: matching velocity with Halley's Comet in its retrograde orbit. With a 162° inclination, this requires nearly reversing your orbital direction - an astronomical 16+ km/s plane change. Only attempted once (by Giotto in 1986 flyby), never achieved.
Achieve the highest possible spacecraft velocity using a Jupiter gravity assist followed by a close solar perihelion burn (solar Oberth maneuver). Dive to within 4 solar radii, perform a powerful burn at maximum velocity, and escape the solar system at over 60 km/s - fast enough to reach 100 AU in 25 years.
Break the speed record to the edge of the solar system. Voyager 1 took 35 years to reach 100 AU - you must do it in under 10 years. This requires an aggressive multi-planet gravity assist sequence culminating in a close solar flyby. Push spacecraft velocity to the absolute limit.
