What if Titan Dragonfly had a Fusion Engine?

In a little over four years, NASA’s Dragonfly mission will launch into space and begin its long journey towards Titan, Saturn’s largest moon. As part of the New Frontiers program, this quadcopter will explore Titan’s atmosphere, surface, and methane lakes for possible indications of life (aka. biosignatures). This will commence in 2034, with a science phase lasting for three years and three and a half months. The robotic explorer will rely on a nuclear battery – a Multi-Mission Radioisotope Thermal Generator (MMRTG) – to ensure its longevity.

But what if Dragonfly were equipped with a next-generation fusion power system? In a recent mission study paper, a team of researchers from Princeton Satellite Systems demonstrated how a Direct Fusion Drive (DFD) could greatly enhance a mission to Titan. This New Jersey-based aerospace company is developing fusion systems that rely on the Princeton Field-Reversed Configuration (PFRC). This research could lead to compact fusion reactors that could lead to rapid transits, longer-duration missions, and miniature nuclear reactors here on Earth.

The 9th Annual Achieving Mars Workshop Report has been Released! How to Make Mars Affordable…

This past summer (June 14th to June 16th), representatives from the public space sector, the commercial space industry, and academic institutions convened at George Washington University in Washington D.C. for The Ninth Community Workshop for Achievability and Sustainability of Human Exploration of Mars. The invitation-only event was hosted by Explore Mars, Inc., a non-profit organization dedicated to fostering international collaboration and cooperation between government and industry to achieve the human exploration of Mars by the 2030s.

The purpose of this workshop is to identify activities that will help prepare for missions to Mars by the 2030s. In particular, the workshop sought to address how a sustainable program of human Martian exploration can be achieved. The highlights of this event were recently shared with the release of the Achieve Mars (AM) IX Report, which established priorities and science objectives for future missions to Mars. The authors also made several recommendations for how cutting-edge technologies could play a role, how the health and safety of astronauts can be assured, and how Mars and Earth can be protected from possible contamination.
