Develop these space based power systems, which includes radioisotope fueled systems and reactor based systems to take the human race further than previously thought possible.
Howe Industries has been the recipient of multiple grants from federal agencies, including NASA (and NASA NIAC), DARPA as well as the NSF. In addition to the ThermaSat CubeSat propulsion system, Howe Industries has developed the solid-state, Advanced Thermoelectric Generator (ATEG), new fuel for nuclear thermal propulsion, and the even more high-tech nuclear Pulsed Plasma Rocket.
Other projects range from debris de-orbiting to a rover for the surface of Mercury (which will be both powered and cooled using ATEG). The company is also investigating the application of their extensive knowhow towards the development of a compact fission-power station for the envisioned lunar base.
A nuclear thermal rocket for manned exploration of Mars, the Moon, or space colonization.
Nuclear electric propulsion using Advanced Thermoelectric Generators (ATEG)s reaching over 20% efficiency.
Low cost, rapid debris de-orbiting for less than $3k per kilogram of removed mass from Earth orbit.
Pulsed Plasma Rocket: Shielded, Fast Transits for Humans to Mars
Howe Industries is investigating a system that may produce 20,000 lbsf of thrust with an Isp of 5,000 s. The system is derived from the Pulsed Fission Fusion  concept but the Pulsed Plasma Rocket (PPR) is smaller, less complex, and more affordable. The performance of a propulsion system with high Isp and high thrust allows missions throughout the solar system and beyond which are not possible with current technology. Human missions to Mars in two months are possible.
Alternatively, heavier ships containing shielding against Galactic Cosmic Rays are enabled so that the dose to the crew is reduced to negligible levels. This may be preferable for Mars missions or may enable human missions to the Asteroid Belt in acceptable timeframes. Additionally, a mission to the 550 AU location where the Sun’s gravitational lens focuses can be considered. For this study, we intend to focus on the large, heavily shielded ship to transport humans and cargo to Mars for the development of a Martian base.
