Martian in situ propellant production (ISPP) has a fundamental advantage over lunar ISPP because it has much greater leverage. The value of Martian ISPP per liftoff far exceeds that for the lunar ISPP. This study analyzes the challenges and complexit

The inspirational paper by Ash, Dowler, and Varsi in 1978, proposing to utilize in situ resources on Mars (ISRU) rather than bringing them from Earth, originated the field of Mars ISRU that has been the subject of research ever since. In this paper,

This study modeled the performance of a full-scale Mars in situ resource utilization (ISRU) system to produce 30 metric tons of liquid O2, operated for 14 months at half-hourly intervals as the Mars environment changes diurnally and seasonally. We co

A critical unknown is how life originated on Earth. Was it seeded from elsewhere, or did it generate spontaneously from indigenous nutrients? The current vogue is the belief system that life will evolve on a planet with water, carbon dioxide, and war

60+ years of planning for a human mission to Mars are documented, based on Portree’s superb history. Starting with von Braun’s vision of the 1950s, many attempts were made to define a feasible human mission to Mars. Development of nuclear thermal
