KISS studies convene experts from Caltech, JPL, and the wider space community to develop ideas and concepts that can revolutionize space science and engineering.
Asteroid 99942, also known as Apophis, will make a close approach to Earth on April 13, 2029, coming within 31,860 kilometers of Earth (within the geostationary belt), presenting a unique opportunity to study its characteristics and…
Understanding carbon stores and fluxes in desert environments is crucial to reach conservation, regeneration, and carbon goals locally and globally. In desert landscapes, carbon is primarily stored as inorganic carbon in the so-called caliche layer and…
As the United States and its international partners prepare to expand human and robotic exploration of the Moon, Mars, and beyond, the need for precise, autonomous timekeeping and navigation has become critical. Current approaches rely on…
In recent decades, astronomers have discovered thousands of exoplanets, some like planets within our solar system, others unlike anything in our solar system. The sample thus far exhibits significant diversity and represents an opportunity to advance…
Future space exploration missions will increasingly depend on autonomy not as a convenience, but as an operational necessity. Missions to distant worlds such as Europa, subsurface explorers operating beneath ice shells, swarms of aerial or terrestrial…
This study brings together experts from across science, engineering, and the emerging commercial space sector to tackle a central challenge: how to make ambitious Moon and Mars science missions dramatically more affordable and achievable in the…
For centuries, humanity has looked to the skies with curiosity and wonder, seeking to understand whether we are alone in the universe. While that question remains unanswered, our solar system offers tantalizing clues—oceans beneath icy crusts,…
The study of the organic inventory of planetary materials occurs at an intersection of many fields including chemistry, biology, geology, and planetary science. In recent years, simple and complex organic materials have been identified and occur…
The surface and subsurface of any worlds beyond Mars still remain unexplored or underexplored. Yet it is these worlds that hold the key to some of the greatest questions in planetary science – for example, the…
