Trans-Neptunian Objects have gained interest in lieu of the success of the New Horizons mission. This paper seeks to further the design possibilities for such missions by offering sixteen trajectories to TNO’s by incorporating a Delta-VEGA maneuver, which allows for increased payload mass. These trajectories were simulated using Spaceflight Solution’s Mission Analysis Environment software, which allowed for constraining of mission parameters for optimization. The trajectories were made to have a C3 below 40 km2/s2, minimized transit time, and minimized ΔV. Results are visualized in Figures 3-6 as well as Table 1, which contain all relevant descriptive …

In the future, a hazardous asteroid will find itself on a collision course with Earth. For asteroids of moderate size or larger, a nuclear device is one of humanity's only technologies capable of mitigating this threat via deflection on a timescale of less than a decade. This work examined how the output neutron energy from a nuclear device standoff detonation affects the deflection of a notional asteroid that is 300 meters in diameter and composed of silicon dioxide at a bulk density of 1.855 g/cm3. 14.1 MeV and 1 MeV neutron energy sources were modeled in MCNP to …
