As we explore space, we learn more about Earth and ourselves. Explore, experience, and engage with a Mars-like expedition in wilderness areas and discover planet Earth.

“I think fundamentally the future is vastly more exciting and interesting if we are a spacefaring civilization… You want to be inspired by things. You want to wake up in the morning and think the future is going to be great. And that is what being a spacefaring civilization is all about.” “Failure is an option here. If things are not failing, you are not innovating enough.”

Elon Musk.

As a community, travel through space by engaging in immersive simulations, experience weightlessness, and study alien planets. See firsthand existing technologies in the aerospace industry and look at future possibilities on how space development and exploration transforms the Earth and people for the better. Explore the challenges of living on Mars and learn about sustainable development through field excursions and science in remote wilderness areas that resemble the geology and landscapes found on Mars. Understand the importance of climate for the development of life, gain appreciation for the wonder and awe of nature, and learn about the failures of humans to develop sustainably. Investigate and connect with the web of life and the “planetary intelligence” that life on Earth represents. Camp and engage in wilderness survival skills, group meal planning, food preparation, self-reliance, and teamwork all the while fostering leadership skills, resiliency, and grit. The educator on tour is deeply connected to the aerospace industry in Colorado, which is at the center of the space program in the United States. Learning and college course credit are guided by PhD Aerospace Professional Dr. Eligar Sadeh.

“The consequences of scientific illiteracy are far more dangerous in our time than in any that has come before.” “Ignorance is not an option.”

Carl Sagan

“We came this way to explore space, and we discovered Earth.”

Apollo Astronaut


Start and Finishing Point:

Denver, Colorado



Expedition briefing and an immersive Art Experience on Alien Civilizations will be your focus today. Students take part in an immersive art experience focused on alien, intelligent civilizations and engage in an exoplanet, alien world experience. Inquire how rare Earth is and the multiplicity of drivers that affect habitability and sustainability on Earth. Students are introduced to the Drake Equation and explore uncertainties in determining just how many civilizations exist elsewhere in the cosmos. Discuss here the ethical implications of extraterrestrial intelligent civilizations. For the past 60 years, humans have developed and explored space and this decade humans will become interplanetary on the moon (NASA) and Mars (SpaceX). Explore social and cultural aspects and implications of humanity as a spacefaring species.

Meals:  D

Learn about space development and exploration, cosmology, and planetary science through experiential and immersive experiences in science and technology. See hardware being developed at the center of the aerospace industry in the United States. Inquire and discuss the state and capabilities of aerospace technology. Experience immersive Science on a Sphere or a planetarium presentation on planetary science and cosmological dynamics within the context of the development of Mars and Earth.

Meals:  B,L,D

Experience astronaut analog training through weightlessness. Train on simulators for developing and exploring space, and experience a spacesuit mission. Engage, explore, explain, elaborate, and evaluate astronaut training experiences.

Meals:  B,L,D

Trek the highest mountain in the Rocky Mountains and see firsthand at a nearby superfund site how living off the land with resource extraction leads to environmental degradation. The Rocky Mountain highest peak, Mount Elbert, beckons. Start early to gain this impressive peak, and from its lofty summit of 14,433 feet take in the immensity of Colorado’s Rocky Mountains and expansive mountain wilderness. Visit the mining museum in Leadville. Discuss how we can live off the land more sustainably. Inquire how and in what ways should we live off the land on Mars? Should we be guided by ethics to protect the environment of Mars? Explore issues of planetary protection comparing the Earth and Mars.

Meals:  B,L,D

Engage in Field Science, and explore the need for sustainable development on Mars and Earth. You will live in a basecamp for a Mars Analog Expedition. Camp in the Mountains or Red Canyon wilderness areas. Develop a project plan for the Mars expedition to address sustainable development drawing on STEM disciplines of cosmology, planetary science, physics, biology, geology, environmental sciences, and human factors. Experience scientific and technology related fieldwork and project-based learning. Engage in journaling, discussion with experts, simulations, project planning and realization, and group presentations.

Meals:  B,L,D

Outline and develop a project report on the Mars Expedition covering all aspects of the program, including STEM disciplines, project development, human factors, and sustainable development. The development of the project report takes place as part of the post-course work following the Mars Expedition journey. This work fulfills college credit. We will debrief following our expedition before our trip concludes in Denver.

All of our USA tour leaders are certified in First Aid and CPR and registered as official guides with the national parks. All of them are trained to guide hikes.



Introductory adventures are designed with the first time trekker in mind. They are challenging enough to make it a real adventure holiday, however the daily physical exercise is around six to eight hours and altitudes generally less than 4,200m. Introductory adventures are not necessarily easy. There will be some long steep ascents and some rough ground to cover. Remember trekking rarely involves flat terrain. Two to three months prior to departure you should spend thirty minutes to one hour exercising, three or four times per week eg. Hard walking, jogging or cycling. To prepare for a walking holiday we recommend you take every opportunity to walk up and down stairs and/or hills, for leg strengthening and aerobic fitness. Please remember the fitter you are the more you will enjoy your holiday.
