SpaceX is set to launch its Dragon cargo spacecraft atop a Falcon 9 rocket on Saturday, February 18th for a NASA-contracted mission to the International Space Station that will deliver supplies, scientific instruments, and hardware to the crew of the orbiting laboratory. The mission will also usher in a new era for SpaceX as they christen their use of the launch pad, which will help fulfill the companys most ambitious space-faring goal: the colonization of another planet.

The mission will be launched from the iconic Launch Complex 39A at Kennedy Space Center which saw the liftoff of Apollo 11 as well as many Space Shuttle missions that helped place the Hubble Telescope and the space station in orbit. SpaceX will conduct a hold-down firing of the Falcon 9s engines this weekend at the historic launch site in preparation for next Saturdays liftoff of Cargo Resupply Service Mission 10.

Launch Complex 39A has not been used since 2011 and is now leased by SpaceX for future launches of the Falcon 9, the upcoming Falcon Heavy, and one day, the Interplanetary Transport System which CEO Elon Musk hopes will shuttle humans to Mars.

The infrastructure of Launch Complex 39A has also been renovated by SpaceX to accommodate NASAs Commercial Crew Program, in which the federal space agency has contracted the Hawthorne, California-based private space firm to shuttle astronauts to the space station beginning sometime in 2019.

SpaceX will utilize its still-in-development Crew Dragon spacecraft (a variant of the Dragon being used for next Saturdays cargo run) to transport NASA astronauts to low-Earth orbit after being launched from LC-39A. These commercial crew missions will mark the first time a manned spacecraft has been launched from American soil since 2011after the Space Shuttle made its final flight in 2011, NASA has been dependent on the Russians for ferrying their astronauts to the space station (at a cost of around 80 million dollars a seat).

Until then, SpaceX has plenty of missions to keep the firm busy. After an explosion of its Falcon 9 rocket destroyed a customer satellite and Cape Canaveral launch pad, SpaceX was grounded for 4 months before returning to flight last month from Californias Vandenberg Air Force Base. With its Falcon 9 back in action and now that LC-39A is ready, SpaceX intends to catch up with its long manifest of scheduled private commercial satellite deliveries by launching every 2-3 weeks this year. The aerospace company reportedly has 70 missions on its backlog worth over $10 billion combined.

These launches will include a few landmark events for SpaceX. LC-39A will see the first flight of the Falcon Heavy which Musk claims will be the most powerful rocket in operation by a factor of two and will have deep space capability for launching uncrewed scientific missions to Mars. SpaceX also hopes to achieve the first launch of a flight-proven orbital-class rocket that was safely brought back to Earth following a previous mission.

Just a few weeks ago at its McGregor, Texas rocket development facility, SpaceX conducted a successful static fire test of the Falcon 9 booster that launched Cargo Resupply Mission 8 last April. That resupply service launch also resulted in a milestone for SpaceXthe first successful landing and recovery of a rocket on their autonomous drone ship at sea, the Of Course I Still Love You.

This recovered Falcon 9 booster will be reused for the upcoming delivery of the privately-owned SES-10 satellitea mission that will also be launched from LC-39A sometime in March of this year. Elon Musk says this mission, if successful, will be an important milestone for SpaceX as the firms long-term goal is to send humans to Mars for permanent settlement and make humanity a multiplanetary species. Musk claims that rocket reusability is the key to accomplishing that.

This year will be a real test for SpaceX to see if they can clear that backlog of launches, push forward with the monumental tasks of flying the powerful Falcon Heavy that will help establish cargo route with Mars, and fly a reused orbital rocket for the first time in aerospace history. Elon Musk hopes that these steps will culminate into his grand vision for sending colonists to Mars in over a decade from Launch Complex 39A and next Saturdays liftoff which is slated for 10:01 AM ET from the historic NASA site, will clear a path for SpaceX to pursue those ambitious goals.

SpaceX's Road to Mars to Begin With First Mission From Iconic Apollo 11 Launch Pad - Observer

Todays businesspeople are very excited about launching into the stratosphere. Whether its Elon Musks SpaceX, Richard Bransons Virgin Galactic, the Mars One mission, or a slew of other aerospace enterprises, a host of companies are trying to help humans leave the rocky planet weve called home for the past six million years. But some critics argue that instead of finding a nook elsewhere in the solar system, we really ought to be focusing on solving the issues with our own planet.

Ron Garan, a former NASA astronaut, believes we should not be abandoning hope for continued life on planet Earth in favor of rubbing shoulders with Martians. He has spent time on the International Space Station (ISS), done four spacewalks, and has been awarded both the NASA Exceptional Service medal and the NASA Space Flight medial. Back on land, Garan spends his time focusing on bettering the home we already have. Being so far away from Earth makes you see how similar and interconnected everything is, he says, rather than us compartmentalizing home.

To be clear, Garan isnt opposed to exploring the notion of colonizing Mars: Its just that we should be using the innovative technologies were developing to live up there to make life better down here. Human curiosity is one of the biggest drivers for space exploration, and it keeps us hungry to continuing wanting to innovate and solve these problems, he says.

It may be a moonshoot, but perhaps if we aim for the moon, well land on the stars.

This conversation has been lightly condensed and edited for clarity.

Considering you are one of the few people who have left Earth, how have you come to form the opinion that we shouldnt colonize Mars?

I think we should explore other planets, but I dont think we should abandon this planet to go live on Mars. It just doesnt make any logical sense that we would leave this planet for an inhospitable one like Mars. First of all, if we cant even terraformwhich is to control our climate and environmentour own planet, what makes us think that we can go to another planet and control the environment there? If we developed the capability to terraform and create atmospheres and climates on other planets, then we should apply that capability to benefit our home planet.

From Elon Musk to Richard Branson, private entrepreneurs are sending a lot of money up into space. Would it be best to redirect that capital toward solving the problems that already exist on Earth?

I think funding should go to both. Space is our future; we need to devote resources and time and effort toward further exploration of our solar system, including human exploration. The primary reason for doing this is not so that we can have a plan B, via having another planet we can go live on, but instead so that we can use the technology thats developed through those efforts to help us here on Earth.

Carl Sagan basically said that for the foreseeable future, Earth is where we make our stand. So if there is nowhere else we can go right now, we need to take this really seriously.

Have you always felt this way, or was there a moment when you realized the importance of focusing on the Earth instead of the stars?

Ive always had the idea that everyone has a responsibility to leave this place a little bit better than how they found it. But going to space broadened, reinforced, and amplified that opinion.

The Earth is just incredibly beautiful when viewed from space, and all those buzzwords youve heard astronaut after astronaut say about how beautiful and tranquil and peaceful and fragile this planet looks from spacethose are all true. It really does look like this jewel in the blackness of space; a fragile oasis. I try to use this perspective of our planet to inspire people to make a difference, mind the ship, and take care of our fellow crewmates on Spaceship Earth.

Why are so many people obsessed with getting off planet Earth?

I wanted to be an astronaut ever since July 20, 1969. That was the day when I, along with millions and millions of people all around the world, watched those first footsteps on the moon on TV. I wouldnt have been able to put it in these words at the time, but even as a young boy, on some level I realized that we had just become a different species. We had become a species that was no longer confined to this planet, and that was really exciting to me.

I wanted to become a part of that group of explorers that got to step off the planet and look back upon ourselves. I think continuing that exploration out into the solar system and beyond is part of human nature. We are explorers by nature. We want to expand our knowledge and expand our understanding of our universe.

Is it common among astronauts that once you finally leave Earth and can look back upon it from space, you have an urge to go straight back to protect it?

I dont want to speak for other astronauts, cosmonauts, or taikonauts, but most of the people I know whove had this experience have come back with a deeper appreciation for the planet that we live on. And its not just an appreciation for the planetits appreciation for the living things on the planet, too.

One of the things I experienced in space is what I can only describe as a sobering contradiction: a contradiction between the beauty of our planet and the unfortunate realities of life for a significant number of its inhabitants. Its obvious from space that life on our planet is not always as beautiful as it looks from space.

The other thing Ive experienced was a profound sense of gratitude: gratitude for the opportunity to see the planet from that perspective, and gratitude for the planet that weve been given. Being physically detached from the Earth made me feel deeply interconnected with everyone on it in some way that I really cant fully explain. Its very obvious from that vantage point that we are all not only deeply connected, but also deeply interdependent as well.

What new discoveries have we uncovered in our exploration of the universe that have been particularly revolutionary back on Earth?

Theres the technology side, and theres then theres perspective. Perspective is very powerful. That first time that we looked back and saw this planet from spaceEarthrisewas incredibly revolutionary. That photograph of Earthrise is certainly the most influential environmental photograph ever taken. It was credited for inspiring the first Earth Day in 1970, and its helped launch the modern environmental movement. It really shows the truth, the reality of the world we live in; that were on this oasis, and its all we have.

So theres that aspect of it, but theres also all the technology that comes from the space program, whether its computing technology, energy production through things like solar energy, or all of the implications for medicine and medical diagnostics. We do a tremendous amount of Earth observation from space that gives us a profound increase in understanding of our planet and its life-support systems that we would not have insight into if we didnt have a space program.

Why do you think there are so many conversations about Martian colonization? Have we lost hope for Earth?

This idea that we are going to abandon Earth and go live on Mars is utter nonsense. Its illogical. It makes perfect sense to expand human presence to Mars, but were not going to abandon Earth. If we had the capability to colonize and terraform Mars to make it habitable for humans, then we certainly could control whats happening on our own planet, which has a head start of millions of years.

What conversation should we be having instead?

The first place we should establish a permanent human presence in our solar system is the moon, our closest neighbor. And then from there, establish transportation infrastructure to allow regular flights between the Earth and the moon. Then from there, we could use it as a jump-off point and have that be a transportation hub to the rest of the solar system. That makes perfect sense to me.

We need to basically take parallel paths: We need to be exploring the solar system because of all the benefits to humanity that that will incur, while also devoting as much effort to being able to control the life-support systems of Spaceship Earth.

If we expand milestones such as the accomplishment of the Sustainable Development Goals (SDGs) by 2030 and having complete decarbonization by 2050 out to 2068which is the 100-year anniversary of EarthriseI believe we should have complete control of the life-support systems on our planet by then. If we had complete control of the chemical constituents of our atmosphere, soil, land, and oceans, wed be able to monitor it and adjust itand optimize it for life.

Why are we having more conversations about living on Mars than the potential of being able to control our own atmosphere on Earth? Learning how to counteract climate change and other environmental factors here instead of establishing colonies elsewhere seems far more beneficial.

Well, its a moon shot, right? Its something thats going to take a lot of effort and a lot of time to accomplish, but we started this conversation off with terraforming Mars. Its a lot easier to control our own atmosphere and our own oceans than it is to create an entirely new atmosphere.

What are you currently trying to achieve back on Earth?

Ive got a non-profit that I founded and am still involved in, and I have a lot of social enterprises that Im involved in. Most of the stuff I work with in that sector is around being able to provide clean water to folks, because I think its really important to do that in an environmentally, financially sustainable way.

Im also involved with an effort called Constellation, which is bringing together a coalition of international astronauts, visionaries, and futurists to put out a call to the world to crowdsource and co-imagine a vision of our future. Were not going to be able to get to the vision of our future we want if we dont learn how to work together on a planetary level, not just a local level.

My primary day job is working as the chief pilot for a company called World View, which is trying to launch all kinds of thingsincluding peopleto the edge of space in high-altitude balloons. This project has tremendous environmental capabilities as far as being able to hover these platforms over a specific area of interest to do things like monitor the oceans, coral reefs, or how much CO2 is in the atmosphere. From it, we might be able to develop better ways to do climate modeling, weather predictions, and agricultural optimization.

For those who would still want to go live on Mars, what kinds of over-romantic notions do people have about living in space?

You cant be claustrophobic, because if youre going to Mars, youre gonna be in a can for six to eight months. And once you get there, youre still gonna be living in a tin can. There are a lot of things that define the beauty of life on our planet, like the breeze in your face, mist on a lake, and the sound of the birds. If youre going to live on Mars, youre not gonna have that for the rest of your life. Thats not so romantic to me.

What is romantic is expanding the body of human knowledge and expanding human presence. Its not going to be all fun. Those pioneers who will eventually be exploring Mars are going have to deal with hardships. Im sure there will be a lot of people who get homesick, which is an interesting thought: When you get that far away from the planet, your definition of home changes radically. Home simply becomes Earth.
