The billionaire founder of SpaceX and Tesla thinks we can start a human colony on Mars as early as 2024, and he's going to try to prove it.
It’s perhaps one of the most looney plans you’re ever going to hear, but SpaceX founder Elon Musk thinks that we could actually start a human colony on Mars in just seven years, and begin building it in five. NASA is working on a more conservative but still wildly ambitious timetable of getting man to Mars in the 2030s, but Musk thinks it could be done a lot sooner, according to remarks from a speech in Australia last week.
Musk said he hopes to start a human colony on Mars in 2024, and starting shipping supplies and setting up a base in 2022. The plan would be to land two cargo ships on the Red Planet in the next five years to set up mining, life support, and power, and then he would send two ships with humans and more cargo ships two years later.
The colony would be able to use carbon dioxide in the Martian atmosphere to produce rocket fuel, which means it wouldn’t be a one-way trip, Musk theorizes. The timeline has plenty of skeptics who question how this will happen when the rocket that would send them there hasn’t even been built yet, to say nothing of political and social obstacles to such a mission.
NASA itself was hesitant to endorse such an ambitious plan.
“NASA is excited to see continued global interest in moving human exploration farther into the solar system, including Mars,” reads a NASA statement as printed by The Australian. “A sustainable crew presence in deep space will require the best of NASA, our international partners and the private sector. Therefore, the agency is studying the deep space gateway concept with US industry and space station partners for potential future collaborations.”
Here’s how NASA describes its own future mission to Mars:
NASA is on a journey to Mars, with a goal of sending humans to the Red Planet in the 2030s. That journey is already well under way.
For decades, the agency and its partners have sent orbiters, landers and rovers, dramatically increasing our knowledge about the Red Planet and paving the way for future human explorers. The Curiosity rover has gathered radiation data to help us protect future astronauts, and the upcoming Mars 2020 rover will study the availability of Martian resources, including oxygen.
There is more to learn as we expand humanity’s presence into the solar system: Was Mars once home to microbial life or is it today? Can it be a safe home for humans? What can the Red Planet teach us about our own planet’s past, present and future?
Building on the robotic legacy, the human exploration of Mars crosses three thresholds, each with increasing challenges as humans move farther from Earth: Earth Reliant, the Proving Ground, and Earth Independent.
Earth Reliant exploration is focused on research aboard the International Space Station. The orbiting microgravity laboratory serves as a world-class test bed for the technologies and communications systems needed for human missions to deep space. Astronauts are learning about what it takes to live and work in space for long periods of time, increasing our understanding of how the body changes in space and how to protect astronaut health.
We’re also working with our commercial crew and cargo partners to provide access to low-Earth orbit and eventually stimulate new economic activity, allowing NASA to continue using the station while preparing for missions beyond.
Next, we move into the Proving Ground, conducting a series of missions near the moon — we call it “cislunar space” — that will test the capabilities we will need to live and work at Mars. Astronauts on the space station are only hours away from Earth, but the proving ground is days away, a natural stepping stone to a Mars mission, which will be months away from home.
The first of these missions will launch NASA’s powerful new rocket, the Space Launch System, from NASA’s Kennedy Space Center in Florida. The mission will carry the Orion spacecraft (without astronauts) thousands of miles beyond the moon during an approximately three week mission (Watch Mission Animation Video). Next up, astronauts will climb into Orion for a similar mission, traveling farther than humans have ever traveled before.
Also in the 2020s, we’ll send astronauts on a yearlong mission into this deep space proving ground, verifying habitation and testing our readiness for Mars.
Another proving ground milestone is the Asteroid Redirect Mission. NASA will send a robotic spacecraft to capture an asteroid boulder and put it in a safe orbit around the moon. Astronauts on Orion will then explore the asteroid, returning to Earth with samples. This two-part mission will test both deep space spacewalking and sampling techniques and Solar Electric Propulsion, which we’ll need to send cargo as part of human missions to Mars.

Finally, we become Earth Independent, building on what we’ve learned on the space station and in deep space to send humans to low-Mars orbit in the early 2030s.
This phase will also test the entry, descent and landing techniques needed to get to the Martian surface and study what’s needed for in-situ resource utilization or “living off the land.” NASA is already studying potential “Exploration Zones” on Mars that would offer compelling science research and provide resources our astronauts can use.
Science missions are already in the Independent phase, with the next rover due in 2020. We will also conduct a round-trip robotic demonstration mission with sample return in the late 2020s.
Mars is the next tangible frontier for human exploration, and it’s an achievable goal. There are challenges to pioneering Mars, but we know they are solvable. We are well on our way to getting there, landing there, and living there.
