Frankly, I was ignorant. I freely admit that. Before I joined the cast of the National Geographic series, Mars, I didn’t know very much about Mars ― and to be honest I didn’t really care. Like many people, I didn’t see how it related to me and why we should spend the money to go to Mars when there are so many problems in the world today that I deemed more important.

But as I prepared for my theatrical role as a crew member of the first mission to Mars, something wonderful happened. As I studied for my part by watching videos, reading articles, and finding out as much as I could about how and why we plan to send humans to Mars, to my great surprise I found my perspective changing. Later, when I was on the set, I found an infectious passion among the crew and cast. I wasn’t the only one who was transformed by our participation in Mars. Many of my fellow cast members also discovered themselves as being passionate advocates for making humanity a multi-planet species. We all realized that this was not like an ordinary film project. Instead, we were part of something that was bigger and of more lasting importance. We had the potential to inspire students and show the world that sending human to Mars will be one of the most important and historic events in human history.

We need big dreams. Children in France (where I’m from) don’t seem to have big dreams these days. In fact, I’m not sure that they are even aware that sending humans to Mars is no longer science fiction but is now within our reach. I was born in 1981, and many people in my generation simply don’t believe that we as a species are capable anymore of doing great things. And I find that sad and even a little scary. This wasn’t the case when my parents were growing up. The world was far from perfect, but they had big dreams. My parents told me that the most amazing thing that they remember ― the event that inspired them and made them hopeful for the future ― was when the Apollo 11 astronauts first stepped foot on the surface of the Moon. They made small steps on the Moon, but it was a giant leap forward for humanity, and they came in peace for all humanity. Unfortunately, the most transforming memory I have (and I’m sure it’s true of my generation as a whole) is the September 11th attacks – clearly a very significant event, but not the type of event that makes anyone hopeful for the future. Sending humans to Mars, however, is my generation’s opportunity for a positive future, and we should embrace it.

Why should humans venture to Mars? In some sense, it is to fulfill a longing in our collective psyche. Humanity has dreamed of walking on Mars since travel above the Earth’s surface became feasible… Those dreams seemed to be on the verge of being realized with the dawn of the Space Age in the mid-20th Century, but for decades Mars remained out of reach to human explorers on site. That frustrating situation has resulted in what many have come to see as Mars being perpetually “20 years away.”  In the terminology used for space launches, we have been in a “hold” for the past 30 years. Today, however, we can finally say that the countdown clock is running. We are going to Mars, twenty years and counting! If we stay the course, the first humans will set foot on the Red Planet by the year 2033.

New technologies have become available that have allowed us to take a fresh look at how to approach human Mars missions and, as a result, to tackle the hardest technical problems that had previously led to a hold in the countdown. And these approaches have given us the ability to design an architecture that can be brought on line incrementally, which keeps the annual expenditures within a reasonable projected NASA human spaceflight budget.

The key to this architecture is to separate much of the supplies and equipment and send them in advance of the crew.  By prepositioning equipment, supplies, and even return rocket stages (more than 80 percent of the total mass), using propulsion systems such as solar electric propulsion (SEP) that are extremely energy efficient for long-haul cargo missions, we can save more than half the costs versus transporting everything using chemical propulsion systems that are needed to reach orbit.

On the other hand, the Space Launch System (SLS) is the key to placing large blocks of payload into Earth orbit.  An analogy here on Earth would be how intermodal shipping of supplies and manufactured goods is accomplished. Short haul is accomplished by trucks or rail, while long haul is accomplished by massive ships.  In this same way, SLS accomplishes the short haul mission to orbit, whereas the cargo is transported over the much larger distance to Mars by solar electric transport ships. The two different propulsion systems, each of which is appropriate for its particular type of mission, are complementary.  And to transport the astronauts, we add in a third element: the Orion multi-purpose crew vehicle as well as a deep-space habitat module, which together provide living space and life support systems.

Why Mars? An Astronaut’s Perspective

I have dedicated my life to answering the great scientific questions of our time, and to the incredible adventure of space exploration.

As a young boy growing up on the South Side of Chicago, I was inspired by the nascent space age. At the age of six I declared that I wanted to be an astronaut. My mother thought that was just fine, as it would encourage me to learn science, and besides, there really was no chance I would ever actually become an astronaut. While I watched the Apollo astronauts walking on the Moon, I imagined that I might some day travel to Mars, to do science, of course. Indeed, I felt compelled to study nature, science, and engineering, eventually earning a PhD in physics. As a scientist, I sent experiments to near-space on high altitude balloons as well as into space aboard the Space Shuttle. But the explorer in me still wanted to go to space in person. To the amazement of my mother, in 1992 I was selected to become a NASA astronaut. I had the privilege to fly five missions on the Space Shuttle, including three missions to the Hubble Space Telescope. I have dedicated my life to answering the great scientific questions of our time, and to the incredible adventure of space exploration.

Of all the planets in our diverse solar system, Mars is unique in that it is the only planet where we can some day live in a somewhat similar fashion to the way we live on Earth. It is large enough to have a suitable surface gravity, and has an atmosphere and resources we can use to live off the land. Scientists using the intrepid Curiosity Rover have shown us that billions of years ago Mars was very much like Earth, with fresh water lakes, rivers, and warm salty seas. At about the same time that Mars was very much a habitable planet, life started on Earth. Did life also emerge on Mars? The question of whether we are alone in the universe is for the first time a discrete scientific question we can answer. We are exploring Mars for signs of past or extant life. We are also preparing to explore Jupiter’s icy moon Europa, which might harbor a habitable ocean, and with future large telescopes we will look for signs of life on planets orbiting nearby stars. But Mars beckons us like no other world, and we will exponentially increase the pace of discovery when we have women and men explorers ― planetary scientists and astrobiologists ― on the surface of the Red Planet performing scientific research. These intrepid explorers will also be opening up a new frontier.

“Are we human because we gaze at the stars, or do we gaze at the stars because we are human?” – Neil Gaiman, Stardust

This is a quote from my favorite movie, Stardust. This quote has defined my life and, I believe, defines humanity as well. I, like every other person on this planet, was born curious. As a kid I marveled at many things on Earth (and off!): the way that the leaves of trees would change color with the seasons, the way that ants moved in cohesion, the way that my fingernails would grow or a glass would shatter when it fell off a table. The world around me was exciting and full of new things.

I, like all children, was born a scientist: curious. But something happens to many children as they grow up, something along the way subdues this natural inclination for discovery that keeps humans alive, that inspires new technology to advance our abilities and that creates new ways to do things. Keeping children curious and engaged in the quest for knowledge through their teen years and into adulthood is essential to the future of humanity.  So the question is, how can we stop kids from losing the drive to discover new things and keep them engaged and excited about the world around them? I believe that we already have an answer: human space exploration.

Why Mars? An Introduction To A 10-Part Series On Sending Humans To Mars

Momentum is steadily and inexorably building toward sending human missions to Mars beginning in the 2030s. While this goal has been an integral part of United States space policy over the past fifty years, the reality of achieving that goal has always seemed so very far in the future. Recently, however, a critical mass of support, technical progress, and scientific momentum has coalesced that may very well finally propel humanity to the Red Planet.

Mars has been the subject of a great deal of media coverage in recent years, with frequent images and scientific updates coming from various United States and international Mars robotic missions. Hollywood has also been drumming the Mars beat, with movies such as The Martian, as well as the upcoming six part National Geographic series, Mars, and the feature film The Space Between Us (with more to come).

As for policy, Congress has included Mars in multiple authorization bills ― and the Senate is currently moving forward with a Transition Authorization bill that contains the most comprehensive language in support of Mars exploration ever to appear in a major bill.

NASA has also embraced this goal, with its Journey to Mars program, and last October it also held its first workshop to investigate potential landing sites for the first human explorers. Industry has also jumped on the bandwagon, with companies such as Boeing, Lockheed Martin, and Aerojet Rocketdyne having released their own proposals as to how to send humans to Mars – and in late September SpaceX joined the chorus when it announced its own ambitious plans.

Recent polls have also shown overwhelming public support for this goal.  Yet, some people still ask Why? Why should we take the time and spend taxpayer dollars? Some even ask why should we take the risks inherent in any space mission ― let alone missions to a planet millions of miles away?

History teaches us that ambitious exploration and innovation projects of this kind have always tended to benefit humanity.

Unfortunately, much misinformation has been disseminated claiming that such missions would cost upwards of $1 trillion.  In reality, none of the current credible plans would require anywhere close to that amount, and in fact they would require far less. (To put this in perspective, all NASA budgets combined since 1958 don’t come close to totaling $1 trillion – even with adjusted dollars).
