The Mars Project, a bold and ambitious endeavor, has captured the imagination of scientists, engineers, and space enthusiasts worldwide.  

With dreams of exploring and eventually colonizing the Red Planet, this mission represents a significant milestone in human space exploration.  

Let’s venture into the Mars Project, its origins, objectives, challenges, and its status as of this year. 

Origins of the Mars Project 

SpaceX Mars Project - Elon Musk

The idea of sending humans to Mars has fascinated humanity for decades, but it gained substantial momentum with the establishment of NASA’s “Journey to Mars” initiative in the early 2010s.  

This initiative aimed to develop the necessary technologies and strategies to send astronauts to Mars in the 2030s. SpaceX, a private aerospace manufacturer founded by Elon Musk, also played a pivotal role.  

Musk’s vision to make life multi-planetary led to the creation of the “Mars Colonial Transporter” (MCT) project, later renamed “Starship”. SpaceX’s aggressive development of the Starship, a fully reusable spacecraft, has brought the idea of Mars colonization closer to reality, with an estimated investment of approximately $5 billion ( AUD 7 823 135 000,00 ) in the project thus far. 

“My vision is for a fully reusable rocket transport system between Earth and Mars that can re-fuel on Mars – this is very important – so you don’t have to carry the return fuel when you go there”, said Musk in a recent interview.  

Before Colonization  

In April 2021, SpaceX won a $2.89 billion (AUD 4.52 billion) NASA contract to develop a spacecraft for landing astronauts on the moon as part of NASA’s Artemis III mission. The lander will be launched by a Starship rocket.  

Currently, the company is testing a 400-foot rocket prototype aiming for Earth’s orbit—a key step before it goes further into space.  

Once successful, Starship will fly regular orbital missions for SpaceX and potentially its clients, including NASA. As the rocket’s capability advances, it’s expected to fly astronauts and tourists to the moon.  

Once its orbital test is completed, SpaceX has indicated that Starship will replace its workhorse Falcon 9 rocket to regularly launch Starlink satellites into space. Starlink satellites deliver high-speed internet globally, including to remote areas with limited access to traditional fiber-optic internet. To date, SpaceX has launched more than 4,000 Starlink satellites at 60 per batch using Falcon 9.  

In contrast, Jeff Bezos’s Blue Origin was awarded a $3.4 billion (AUD 5.32 billion) NASA contract to build a competing spacecraft two years later.  

Under its contract, SpaceX is expected to deliver the lunar lander in late 2025. But after Starship’s first orbital test flight, NASA estimated the timeline could be delayed to 2026 depending on SpaceX’s test progress. 

The Mars Project’s Objectives 

The Mars Project has several key objectives, including: 

Human Exploration 

The primary goal of the Mars Project is to send astronauts to Mars and establish a self-sustaining human presence. This involves developing life support systems, habitats, and technologies to ensure the safety and sustainability of humans on Mars.  

NASA and SpaceX are at the forefront of these efforts, addressing the numerous challenges posed by this ambitious endeavor, including radiation protection, resource utilization, and risk mitigation. 

Scientific Discovery 

Mars is a rich source of scientific discovery. Missions like SpaceX and NASA’s Curiosity and Perseverance Rovers have unveiled valuable information about Mars’ geology and its potential for past microbial life.  

Future missions are set to carry on this research, promising even more revelations. These missions are crucial not only for uncovering Mars’ mysteries but also for preparing for future human exploration of the Red Planet. 


SpaceX has a grand vision: creating a self-sustaining colony on Mars as a backup for humanity in case of Earth’s catastrophic events. This plan involves sending settlers gradually over time, making the colony self-sufficient by using Martian resources, and developing the reusable Starship spacecraft for transportation.  

While the challenges are substantial, including radiation and environmental factors, SpaceX is committed to this long-term goal, aiming to secure humanity’s future beyond Earth.

Futuristic life on Mars

“Mars is the only place in the solar system where life can become multi-planetarian”, said Musk.  

Resource Utilization 

The Mars Project is actively exploring the use of Martian resources like water ice and carbon dioxide to generate essential supplies for colonization.  

This includes extracting water for drinking and oxygen, as well as producing fuel for transportation. This approach reduces the colony’s reliance on Earth, but it presents technological challenges that require ongoing research and development. 

To Mars: 2023 

As of September 2023, the Mars Project has made significant progress.  

NASA’s Artemis program represents a critical bridge to Mars exploration by leveraging lunar missions as a testing ground for the technologies and systems necessary for the more ambitious journey to Mars.  

The Moon serves as a relatively close and accessible destination where astronauts can gain valuable experience in operating in a space environment for extended durations. These lunar missions will help fine-tune life support systems, habitats, and deep-space navigation techniques that are vital for Mars. 

SpaceX’s Starship development is at the forefront of private space exploration. The company has been conducting an aggressive series of tests with Starship prototypes, demonstrating the spacecraft’s capabilities in suborbital flights.  

Starship’s versatility is a game-changer, designed to transport both cargo and crew to destinations like Mars. It offers the potential to carry a significant number of passengers and cargo, significantly reducing the cost per person for Mars missions. 

International collaboration is becoming increasingly important in Mars exploration. Organizations such as the European Space Agency (ESA) and Russia’s Roscosmos have shown keen interest in joining the endeavor.  

Collaboration brings the advantages of shared costs, pooled resources, and diverse expertise, enhancing the overall success and sustainability of Mars missions. 

Robotic missions like NASA’s Perseverance Rover continue to serve as the eyes and ears on Mars.  

Perseverance’s groundbreaking experiments include MOXIE, which seeks to produce oxygen from the Martian atmosphere, potentially unlocking a key resource for future human missions. These robotic explorers pave the way for human exploration by providing critical data and testing technologies in the challenging Martian environment. 

Dr. Steve Mackay, Dean of Engineering at EIT expressed, “As a child in 1969, I still can clearly remember the ‘One Giant Leap for (Wo)mankind’ grainy images of the incredible pioneering 1969 landing on the Moon by Neil Armstrong, Buzz Aldrin (and Michael Collins) – so it is marvellous to continue this tradition of rising to the challenges of space exploration with magnificent engineering solutions as we can see with SpaceX’s Mars project.” 

Challenges Ahead 

Despite significant progress in Mars exploration and colonization efforts, formidable challenges loom on the horizon.  

Foremost among these is the issue of radiation. Mars’ thin atmosphere offers little protection against cosmic and solar radiation, posing a serious threat to astronauts.  

Consequently, the development of robust radiation shielding, and protection mechanisms remains a top priority. Additionally, the sustainability of human life on Mars hinges on advanced life support systems capable of ensuring a steady supply of vital resources such as oxygen, water, and food.  

The challenge of transportation is also paramount, requiring the establishment of reliable and efficient systems not only for the journey to Mars but also for the regular resupply of the colony.  

Furthermore, there is a pressing need to understand and address the psychological and physiological effects of extended space travel on astronauts, as these can have profound implications for well-being and mission success. Tackling these challenges is integral to realizing the dream of a sustainable human presence on the Red Planet. 

The Mars Project represents a thrilling and ambitious venture that continues to capture the imagination of people worldwide. While significant progress has been made, numerous challenges lie ahead.  

Joe Parrish, Manager at Mars Exploration Program (NASA) said, “100 years in the future, I hope we will have set up outposts, maybe even cities on Mars, and traveling to and from Mars will be routine”.  

With international collaboration, continued research, and technological advancements, the dream of sending humans to Mars and establishing a colony on the Red Planet is getting closer to becoming a reality. Humanity’s journey to Mars is a testament to our unwavering spirit of exploration and discovery.
