1. Introduction
Last month, we submitted our updated response to NASA's RFI for Moon to Mars mission objectives. This document outlined our "Selene Mission" architecture, designed to deliver astronauts to the lunar surface. Furthermore, it hinted at the adaptability of our spacecraft for future Mars missions. However, unbeknownst to many, Titans Space has been quietly but diligently developing a comprehensive Mars mission architecture for quite some time.
Titans Space's Crewed Mars Mission: 2032 would have remained a stealth project until 2025, but now that NASA is revamping its Mars Sample Return program, aiming to get Martian rock and soil samples back to Earth sooner and cheaper, we deem the right time to make our intentions public.
The original Mars Sample Return mission was estimated to cost $11 billion and take until the 2040s – a timeline and price tag deemed unacceptable by NASA.
NASA's?new approach seeks innovative designs?to bring down those costs and expedite the mission. NASA is calling on the NASA community to brainstorm a revised plan that utilizes both cutting-edge and proven technologies. Additionally, NASA is looking for proposals from private companies for creative solutions to retrieve the samples by the 2030s. This focus on collaboration and fresh ideas signifies a shift from the previous, more expensive approach.
These recent developments have motivated us to formally propose our capabilities and contribute to this critical space exploration endeavor. We will respond to NASA's upcoming RFI and also share it with the public in due time. For now, this summarized white paper serves to inform the public and all (potential) stakeholders of our planned architecture.?
2. Technical Overview
Reaching the Red Planet demands a mission architecture that not only addresses the technical challenges of long-duration space travel but also ensures the safety and sustainability of crewed missions. In response to this imperative, we present a comprehensive plan for a nuclear-powered crewed mission to Mars. This white paper provides a detailed exploration of the technical intricacies, advantages, and feasibility of our proposed approach.
2.1. Introduction to Nuclear-Powered Interplanetary Travel
Interplanetary travel poses numerous major challenges, chief among them being the need for propulsion systems that can sustain long-duration missions while carrying substantial payloads. Nuclear power offers a compelling solution due to its high energy density and long-lasting operation capabilities. By harnessing nuclear reactions, spacecraft can achieve higher velocities and carry larger payloads, enabling faster and more ambitious missions to distant destinations like Mars.

These behemoth vehicles, leveraging advanced (non-nuclear) propulsion systems and aerodynamic design, transport personnel and equipment from Earth's surface to Low Earth Orbit (LEO) safely and efficiently. The reusability of these spaceplanes significantly reduces launch costs and enhances mission sustainability, making them an integral component of our mission architecture.
2.3. Advanced Nuclear Propulsion Systems
At the core of our mission architecture lie advanced nuclear propulsion systems, namely Nuclear Electric Propulsion (NEP). Nuclear Thermal Propulsion (NTP) systems utilize the heat generated by nuclear fission reactions to heat propellant and generate thrust, offering high thrust-to-weight ratios and short travel times. NEP systems, on the other hand, use nuclear reactors to generate electricity, powering ion thrusters for continuous acceleration and efficient long-duration missions. This topic is covered in section 3, below.
2.4. Mars Spaceships and Space Station
The Mars Spaceships (or Mars Transfer Ships) serve as the primary vehicle for crew transportation and interplanetary travel. Constructed in Low Earth Orbit (LEO) using modular assembly techniques, the Mars Spaceships are equipped with advanced life support systems, radiation shielding, and nuclear propulsion systems for propulsion and power generation.
The Mars Space Station, which we call the Mars Logistics Depot Station or Mars Station, will be equipped with a similar nuclear propulsion system as the Mars Spaceships. The Station's underside (surface facing side) will cradle tanks filled with cryogenic and storable non-cryogenic propellants, readily available for maneuvering and maintaining its position in Martian orbit, as well as to serve as a refueling depot and rendezvous point for spaceships, crew transfer, and resupply operations, enhancing mission flexibility and sustainability.
Outline
2.5. Mars Landers: Descent and Surface Operations
One of the three specialized Mars Landers, referred to as Mars Utility Transporters (MUTs) and pre-loaded within the Mars Station along with other special equipment and machinery (for ISRU as well as scientific research, analysis, and testing), will serve as transportation for the crew to travel to and from the Martian surface. The MUTs utilize a combination of aerodynamic braking, retropropulsion, and precision landing systems to ensure a safe touchdown on the Martian terrain. Once on the surface, crew members establish a base of operations, deploy habitats, deploy In-Situ Resource Utilization (ISRU) technologies, conduct scientific research, and collect samples, laying the groundwork for sustained human presence on Mars.

8. Personal Note from Neal S. Lachman, CEO and Chief of Spacecraft Design, Titans Space
Dearest Readers,
Like most of you, space has always held an irresistible pull on my imagination.
Despite not being particularly religious, my Hindu upbringing fostered a profound respect for the celestial bodies – the sun, moon, and Mars – which Hindus revere as Surya, Chandra, and Mangala.
From gazing at the sky as a child to devouring every scrap of information about the moon landings, I dreamt of one day stepping off the Earth and leaving my footprints on another world. That dream has become the driving force behind Titans Space Industries.
Now you've read about our crewed mission returning Martian samples by 2034, and the ultimate objective: putting humans on Mars. These are audacious dreams, I know, but dreams fueled by unwavering passion (I won't admit it's an obsession) and support of the incredible team at Titans Universe and Titans Space., including Launching Astronaut, Vaseema Hussain MCIAT , Titans Astronaut, Richard Borsboom, and the sisters Zuhal Guvener , Chief Communications Officer, and Sue Guvener , Chief Sales Officer.
Some may call me a dreamer, others might see a touch of madness, others think that I hate vertical rockets or that I hate SpaceX's Starship. But I believe, with every fiber of my being, that this generation holds the key to unlocking the secrets of the cosmos (just not with vertical rockets).
And yes, I confess a personal ambition – to be the first private citizen to walk on the lunar surface and the first human to set foot on Mars. I'm a young 52 today, and I hope to remain fit and healthy without the need of any medication or illness. I'll allow all kinds of scientific studies on/with my body during missions.
This journey, however, is not a solitary one. Titans Space is a family, a collective of brilliant minds working tirelessly to turn science fiction into reality. Also, recently, many people from the general public have started supporting us and believe in our missions. My deepest gratitude goes out to every one of you.
I especially want to acknowledge our Director of Operations and Business Development, Marcus Beaufort , whose unwavering support and brilliance steer us through even the stormiest waters.
To Franklin Ratliff, our Chief Technology Officer, whose genius translates dreams into tangible marvels: Your dedication inspires me every single day. I am amazed by the incredible synergy between your incredible encyclopedic knowledge of aerospace and rocketry and my pragmatic thinking and structural efficiency. I couldn't have wished for a better technology partner.
To everyone who reads this letter, I guess I can come across as an arrogant asshole at times, but your support fuels my fire. I am gratefully loyal to our supporters and I don't forget those who helped us.
While still working in stealth mode, we will strive to share the most important milestones, challenges overcome, and triumphs along the way. From establishing our own large spaceport, to building futuristic spaceships, to the Selene (lunar) mission, and now this Mars mission, we can and will do this together, with your help and support.
Together, let’s make history. Let’s leave our mark not just on Earth, but on the universe itself.
Per audacia ad astra. (Through boldness to the stars.)
