Steam/Nuclear Vehicle - Mars Society Convention

24th Annual International Mars Society Convention - 4 Days


Kumar: Conceptual Design of Steam Propelled and Nuclear Powered Interplanetary Transportation Vehicle for Crewed Exploration Missions

To address the space transportation challenge, we have proposed a steam-propelled and nuclear-powered spaceship for human-crewed exploration to Mars and Beyond. The proposed spaceship utilizes, water extraction module to extract water from asteroids, moons, and other interplanetary bodies to fuel, followed by heating of water through controlled nuclear fission to pressurize steam in a propulsion chamber. Upon attaining a certain pressure limit, the steam is allowed to eject via a spaceship nozzle to propel the vehicle. We can maximize the spaceship’s delta velocity through controlled steam propulsion for faster transit to various interplanetary destinations. Further, we can find water resources at every interplanetary extremity beyond Mars, and heat production can be enhanced through limited nuclear resources. So, it makes the spaceship renewable and sustainable thereby enabling crew for faster and safer interplanetary transit. Finally, we hope that this kind of spaceship may enable future astronauts to attempt deep space exploration missions in the upcoming decades.

The 24th Annual International Mars Society Convention is Thursday-Sunday, October 14-17, 2021. This convention presents a unique opportunity for those interested in the planet Mars to come together and discuss the science, technology, social implications, philosophy and a multitude of other aspects of Mars exploration.

This meeting is interactive. Most of the time the speakers and members are appearing on a Zoom screen. You will be able to grab the mike so you can talk to the people in Zoom.

The Mars Society is the world’s largest and most influential space advocacy organization dedicated to the human exploration and settlement of the planet Mars. Established by Dr. Robert Zubrin and others in 1998, the group works to educate the public, the media and the government on the benefits of exploring Mars and creating a permanent human presence on the Red Planet.
