Joint UTSA-SwRI Study Shows How Radioactive Decay Could Support Extraterrestrial Life

In the icy bodies around our solar system, radiation emitted from rocky cores could break up water molecules and support hydrogen-eating microbes. A University of Texas at San Antonio (UTSA) and Southwest Research Institute (SwRI) team modeled a natural water-cracking process called radiolysis and applied the model to Europa (pictured) and several other worlds with known or suspected interior oceans.

May 22, 2017 – In the icy bodies around our solar system, radiation emitted from rocky cores could break up water molecules and support hydrogen-eating microbes. To address this cosmic possibility, a University of Texas at San Antonio (UTSA) and Southwest Research Institute (SwRI) team modeled a natural water-cracking process called radiolysis. They then applied the model to several worlds with known or suspected interior oceans, including Saturn’s moon Enceladus, Jupiter’s moon Europa, Pluto and its moon Charon, as well as the dwarf planet Ceres.

In Dire Peril: 55 Years Since the Troubled Mission of Aurora 7 (Part 2)

Fifty-five years ago, this week, Scott Carpenter became America’s second man in orbit. Aboard Mercury-Atlas (MA)-7—a spacecraft which he had dubbed “Aurora 7”—the astronaut was tasked with the most comprehensive program of scientific research yet seen on a piloted mission: astronomical observations, visibility and flying evaluations and medical checks. Sadly, as outlined in yesterday’s AmericaSpace history article, his five-hour and three-orbit voyage suffered from severe technical problems, including a faulty pitch horizon scanner and a worrisome decline in fuel quantities in both Aurora 7’s manual and automatic tanks. The result was a mission which remains mired in controversy to this day.

In 1997, the Society began the Gene Shoemaker NEO grant program to help in the global effort to meet the Spaceguard goal of discovering 90% of the 1-kilometer (0.6-mile) and larger NEOs that can impact our planet. The program honors pioneering planetary geologist Gene Shoemaker, who did so much to help us understand the process of impact cratering on the planets and the nature of the NEO population, and seeks to assist amateur observers, observers in developing countries, and under-funded professional observers in contributing to vital NEO research.
