Former President Donald Trump has expressed interest in sending humans to Mars during his presidency. In 2017, he issued a directive to NASA to "lead an ambitious human space exploration program to send American astronauts to Mars."
Objectives of Trump’s Mars Plan
The primary objective of Trump’s Mars plan was to establish a sustainable human presence on the Red Planet. This would involve sending crewed missions to Mars, establishing a base there, and eventually returning to Earth.
Key Components of the Plan
The key components of Trump’s Mars plan included:
- Developing a new spacecraft to transport astronauts to Mars
- Building a lunar gateway to serve as a staging point for Mars missions
- Establishing a permanent human settlement on Mars
- Conducting scientific research on Mars
Challenges and Criticisms
Trump’s Mars plan faced several challenges and criticisms:
- Technical challenges: Developing the necessary spacecraft and technologies for Mars missions is a complex and time-consuming process.
- Cost: The estimated cost of Trump’s Mars plan was in the trillions of dollars, which raised concerns about its affordability.
- Scientific justification: Some scientists questioned the scientific value of sending humans to Mars, arguing that robotic probes could achieve similar results at a lower cost.
Current Status of the Plan
Following Trump’s departure from office, the status of his Mars plan is uncertain. The Biden administration has not yet announced its plans for Mars exploration. However, NASA continues to develop technologies and conduct research that could support future human missions to the Red Planet.

SpaceX’s Mars Mission
SpaceX, led by Elon Musk, has embarked on an ambitious mission to land humans on Mars within the next decade. The first phase involves developing a fully reusable Starship spacecraft capable of carrying large amounts of cargo and crew to Mars.
The Starship is being designed to be launched on SpaceX’s Super Heavy rocket and will be equipped with advanced systems for life support, navigation, and landing. The spacecraft will also be capable of refueling in orbit, allowing it to make multiple trips to Mars without returning to Earth.
Once the Starship is developed, SpaceX plans to send an uncrewed mission to Mars to establish a base and conduct scientific investigations. This will be followed by a series of crewed missions to explore the Martian surface, search for signs of life, and establish a permanent human presence.
SpaceX’s Mars mission is a complex and ambitious undertaking, but Musk believes it is essential for humanity’s future. By establishing a presence on Mars, humans would gain access to vast new resources, expand their knowledge of the universe, and ensure the survival of our species beyond our home planet.
NASA’s Mars 2020 Mission
The Mars 2020 mission is a NASA robotic mission to Mars launched on July 30, 2020. The mission’s primary goal is to search for evidence of past life on Mars and to collect samples for future return to Earth. The mission also includes several other scientific objectives, such as studying the planet’s geology, climate, and atmosphere.
The Mars 2020 rover, named Perseverance, landed on Mars on February 18, 2021. The rover has been exploring the planet’s surface since then, collecting samples of rock and soil. The rover has also taken several high-resolution images of the planet’s surface.
The Mars 2020 mission is a major step forward in our understanding of Mars. The mission’s findings will help us to better understand the planet’s history and its potential for supporting life.
Mars Rover Perseverance
The Perseverance rover is the latest NASA mission to explore the planet Mars. It was launched in July 2020 and landed in Jezero Crater in February 2021.
Perseverance’s mission is to search for signs of past life on Mars, as well as to study the planet’s geology and climate. The rover is equipped with a variety of instruments, including a drill that can collect core samples of rock.
Perseverance has already made some significant discoveries. In April 2021, it found evidence of an ancient river delta in Jezero Crater. This discovery suggests that the crater was once filled with water, and that it may have been a habitable environment for life.
Perseverance is still in the early stages of its mission, but it has already shown great promise. The rover’s discoveries are helping us to learn more about Mars and its potential for life.
