The Journey Back to the Moon: Advancements in Sustainable Space Exploration
Going back to the moon sustainably holds immense significance for scientific advancement. Past lunar missions like Apollo only scratched the surface of what could be discovered. The future is promising, with countless breakthroughs waiting to happen. The National Team, composed of exceptional leaders and experienced individuals, is ready to embark on this journey. Blue Origin brings innovation and modern thinking, while Lockheed Martin, Northrop Grumman, and Draper contribute their extraordinary legacy and expertise. This unique collaboration positions the team to achieve their ambitious goals.
1. Introduction
Returning to the moon is more than just revisiting the same destination. It signifies progress and new possibilities for scientific exploration. The National Team is at the forefront of this endeavor, spearheading the advancements required for sustainable human presence on the lunar surface.
2. The National Team: Outstanding Leadership and Experience
The National Team is comprised of a remarkable coalition of organizations. Achieving great achievements requires exceptional leadership and experience, which is exactly what the National Team brings to the table. With their combined expertise, this team is poised to meet the challenging targets they have set for themselves.
3. The Three-Element Architecture of HLS
The Human Landing System (HLS) consists of three fundamental elements that work together to transport humans to the moon's surface safely.
The Crewed Vehicle: Life Support and Control Systems
The crewed vehicle is the Core component that ensures the well-being and safety of astronauts during their lunar mission. It is equipped with life support systems, intuitive controls, and comprehensive displays that allow the crew to Interact seamlessly with their surroundings.
The familiarity of the crew with the displays and controls plays a crucial role in ensuring safe human spaceflight. The usage of technology derived from the Orion program minimizes the training required and enhances the operational safety of the system.
The Descent Element: Landing Safely on the Surface
The descent element is responsible for the crucial maneuvers involved in successfully landing astronauts on the lunar surface. Developed by Blue Origin, this element incorporates the proven lunar architecture of their Blue Moon project. With advanced thrusters, engineering legs, and a robust system, it ensures a safe and comfortable touchdown for the crew.
The use of Blue Origin's reliable and adaptable BE-7 engine, with a throttling capability down to 20% power level, provides versatility to adapt to various landing scenarios and increases overall mission safety.
The Transfer Element: Bringing the Elements Together
The transfer element, built by Northrop Grumman, plays a vital role in the HLS architecture. It leverages the proven technology and avionics from the Cygnus service module—frequently used by NASA for Cargo resupply missions to the International Space Station. This transfer element takes the crewed and descent elements from a deep space staging orbit to the lunar orbit, enabling the descent element to land the crewed element safely on the moon's surface.
4. Proven Heritage and Technology Demonstrations
The National Team's expertise is not limited to theory; it is backed by proven heritage and successful technology demonstrations.
Orion, Cygnus, and New Shepard
The team's heritage includes contributions from the Orion program, which has been in development for an extended period. Likewise, Cygnus has played a significant role in delivering cargo to the International Space Station routinely. The experience gained from these programs has provided valuable insights and technological advancements that are instrumental in shaping the HLS mission.
New Shepard, Blue Origin's launch vehicle, has undergone numerous successful missions. With a versatile hydrogen engine that can throttle down to 20% power level, it aligns with the goals of HLS, offering increased safety and adaptability during lunar landings.
Testing and Development of Sensors and Avionics
One of the critical aspects of HLS is the extensive testing and development of sensors, avionics, and guidance navigation control systems. Draper has been at the forefront of this endeavor, leveraging their expertise to develop and refine the BB7 technology over several years. The sensors and avionics have undergone rigorous testing, including flights on the New Shepard vehicle that simulate the conditions and environment the sensors will experience during lunar missions.
5. Risk Reduction and Learning Opportunities
The HLS program prioritizes risk reduction and learning from every opportunity. By conducting demonstration flights and practice runs without crew members on board, the team can identify and address potential challenges, thus ensuring the safety and success of future missions.
Demonstration Flights and Practice Runs
The National Team has planned a demonstration flight of the descent element one year before the mission with crew members onboard. This approach provides an invaluable learning experience, allowing the team to practice and refine their procedures and systems without risking human lives. Any issues or unforeseen complications can be thoroughly analyzed and resolved, ensuring a smooth and safe mission operation.
Upgrading and Sustainability
The HLS architecture allows for future upgrades and sustainability. While the initial mission is crucial, the ability to evolve and Continue exploring the moon in a sustainable manner is equally essential. The modular design of the HLS elements enables future missions with upgraded capabilities, thus expanding the scope and longevity of lunar exploration.
6. Utilizing Lunar Resources for Long-Term Presence
Utilizing lunar resources is a critical aspect of enabling long-term human presence on the moon. The National Team has devised a liquid oxygen and liquid hydrogen-based architecture that harnesses the resources available on the lunar surface. These resources can be mined directly from the moon, providing a sustainable and reliable source for fuel, power generation, and other essential needs during extended lunar missions.
The Importance of Safety in Landing on an Unprepared Surface
Landing on an unprepared lunar surface poses unique challenges, but the HLS design has prioritized safety throughout. By separating the crew and descent elements, the risk of engine plume-accelerated particles damaging critical components is minimized. Additionally, with the crew cabin elevated above the surface, the risk of engine contact with the ground during landing is drastically reduced. This design ensures the safety of the crew and the integrity of essential systems.
Engine Out Capability and Dust Mitigation
The National Team's HLS incorporates engine out capability, allowing for contingency plans in case of engine failure. This redundancy further enhances the safety and reliability of the overall system.
Dust on the lunar surface is a concern due to its sharp nature and tendency to cling to surfaces. The placement of the crewed element hatch at a distance from the lunar surface mitigates the issue by minimizing the accumulation of dust particles. This also reduces the risk of dust inhalation, thus ensuring the well-being of the astronauts during their stay on the moon.
Inspiring the Next Generation: Landing the First Woman on the Moon
A significant milestone emphasized by the National Team is the mission to land the first woman on the moon. This historic event has the power to inspire the next generation of students and demonstrate the inclusivity and possibilities of space exploration. By breaking barriers and fostering diversity, the National Team aims to fuel the imaginations of future astronauts and space enthusiasts.
8. Collaboration and Pride: The Power of the National Team
The collaboration between the National Team and NASA is built on trust, expertise, and mutual pride. With hundreds of millions of dollars allocated to task orders across various NASA centers, including Marshall, the collective knowledge and specialized facilities are utilized to their fullest potential. This remarkable team, combining the strengths of both the participants and NASA, represents the spirit of collaboration and innovation that is synonymous with space exploration.
Leaving the Moon with Hope and the Road to Space
Reflecting on the iconic words of Eugene Cernan, the last astronaut to leave the moon's surface during the Apollo 17 mission, the motivation to return to the moon is propelled by the need to inspire hope and build a future enriched by the resources of space. The National Team understands that this is not an easy task, but with determination and resilience, they aim to pave the way for future generations to unleash their creativity and establish a sustainable presence beyond Earth.
