proposed sample-return mission to a comet

MoonRise was a robotic mission concept to the south pole of the Moon. It was proposed in 2010 and 2017 for NASA's New Frontiers program mission 3 and 4, respectively, but it was not selected. If funded and launched by another NASA opportunity, it would focus on the giant South Pole–Aitken basin (SPA basin) on the far side of the Moon between the Moon's South Pole and Aitken Crater, 16° south of the Moon's equator. This basin measures nearly in diameter and in depth. This region is the oldest and deepest observable impact basin on the Moon and provides a window into the deep crust of the Moon a

OCEANUS (Origins and Composition of the Exoplanet Analog Uranus System) is a mission concept conceived in 2016 and presented in 2017 as a potential future contestant as a New Frontiers program mission to the planet Uranus. The concept was developed in a different form by the astronautical engineering students of Purdue University during the 2017 NASA/JPL Planetary Science Summer School. OCEANUS is an orbiter, which would enable a detailed study of the structure of the planet's magnetosphere and interior structure that would not be possible with a flyby mission.
