Factoring Origin of Life Hypotheses into the Search for Life in the Solar System and Beyond
Two widely-cited alternative hypotheses propose geological localities and biochemical mechanisms for life’s origins. The first states that chemical energy available in submarine hydrothermal vents supported the formation of organic compounds and ...

Fundamental Science and Engineering Questions in Planetary Cave Exploration
Nearly half a century ago, two papers postulated the likelihood of lunar lava tube caves using mathematical models. Today, armed with an array of orbiting and fly‐by satellites and survey instrumentation, we have now acquired cave data across our solar ...

Review of nuclear techniques for planetary science
Spaceflight instruments that measure the energy and intensity of gamma rays and neutrons emitted by the surfaces of planetary bodies have been included in planetary science missions since 1966.

An Approach to Science and Risk-Aware Planetary Rover Exploration
This work grapples with the challenge of directing autonomous decision making by planetary rovers conducting science investigations. Most of the related work addresses obstacle avoidance and traversabilty, while less work seeks to directly improve ...

Laser and radio tracking for planetary science missions—a comparison [PDF]
At present, tracking data for planetary missions largely consists of radio observables: range-rate (Doppler), range and angular position (VLBI/$$\Delta $$ΔDOR). Future planetary missions may use Interplanetary Laser Ranging (ILR) as a tracking observable.

Incorporating Physical Knowledge Into Machine Learning for Planetary Space Physics
Recent improvements in data collection volume from planetary and space physics missions have allowed the application of novel data science techniques. The Cassini mission for example collected over 600 gigabytes of scientific data from 2004 to 2017. This
