Elon Musk Reveals How He's Going to Take Us to Mars

It's no secret that Elon Musk wants to take humans to Mars by 2025, but now, for the first time, he will explain how he plans to do it.


The CEO of SpaceX and Tesla and chairman of SolarCity is scheduled to speak before the International Astronautical Congress in Guadalajara, Mexico, today at 2:30 p.m. ET.

In a keynote speech, Making Humans a Multiplanetary Species, Musk "will discuss the long-term technical challenges that need to be solved to support the creation of a permanent, self-sustaining human presence on Mars. His technical presentation will focus on potential architectures for sustaining humans on Mars that industry, government and the scientific community can collaborate on in the years ahead," according to SpaceX.

In a move to generate even more buzz around the highly anticipated speech, Musk shared photos of his Interplanetary Transport System—a powerful rocket engine dubbed Raptor—conducting its first test-firing in addition to some other details:

When compared to the Merlin engines used to power SpaceX's signature Falcon 9 rocket—the one it used to deliver supplies to the International Space Station—Musk said the Raptor's "chamber pressure is almost 3X Merlin, so engine is about the same size for a given area ratio." That means the Raptor is roughly three times more powerful than the Falcon 9's Merlin engine.

Musk's latest reveal shows just how far SpaceX has come since he founded the privately funded aerospace company in 2002. In 14 years, SpaceX went from successfully launching the Falcon 1 rocket into orbit in 2008 to being contracted to launch commercial satellites, as well as resupply the International Space Station.

In previous interviews about his plans for missions to Mars, Musk said the first mission is slated for 2018 when SpaceX plans to launch its so-called "Red Dragon" spacecraft, without a crew and on top of a Falcon Heavy rocket. Then every 26 months—when Earth and Mars's orbits are closest together—SpaceX will launch two more rockets to practice landing large objects on Mars, with full crews expected to make the trip in 2024.

While Musk says his main goal in these trips is establishing a colony for future generations, getting there safely will have its challenges.

Radiation exposure on the way to Mars puts astronauts "at huge risk of cancer [and is] a major open problem that must be solved for the mission to be feasible," Hannah Kerner, executive director of the Space Frontier Foundation, explained to ABCNews.

There are also other issues including the psycho-social effects of space travel as well as the effect of decreased gravity on the human body, Kerner said. And, as with all space travel, she warned, "there will surely be more vehicle failures and potential loss of life on the path to Mars."

So why do it?

At the event in Hong Kong in January, Musk described the desire to go to Mars this way:

"It's really a fundamental decision we need to make as a civilization. What kind of future do we want? Do we want a future where we're forever confined to one planet until some eventual extinction event, however far in the future, that might occur? Or do we want to become a multi-planet species and then ultimately be out there among the stars?"

And while Musk's main purpose to take us beyond our blue planet may be to save us from possible extinction, he also admitted, "What gets me more excited is that this would be an incredible adventure. It would be like the greatest adventure ever."

Worldwide Clean Energy Investments Hit $333.5 Billion Last Year

Global investment in renewable energy hit $333.5 billion in 2018, the second-highest on record, according to a new analysis from Bloomberg New Energy Finance (BNEF).

That's a 3 percent jump from 2016 and 7 percent short of the $360 billion record set in 2015.

How Blockchain Could Boost Clean Energy

By Jeremy Deaton

Bitcoin, the much-hyped cryptocurrency, made headlines recently for driving a surge in power use. Around the globe, digital entrepreneurs are 'mining' bitcoins by solving complex math problems, using supercomputers to get the job done. Those supercomputers use a ton of power, which largely comes from coal- and gas-fired power plants spewing gobs of carbon pollution.

But while hackers wreak havoc on the climate, blockchain, the bleeding-edge technology behind bitcoin, could one day help clean up the mess. Climate wonks say blockchain has a role to play in the clean-energy economy, helping homeowners sell electricity, allowing businesses to trade carbon credits, and making it easier for governments to track greenhouse gas emissions.

Post-Fire Landslide Problems Likely to Worsen: What Can Be Done?

By Lee MacDonald

Several weeks after a series of wildfires blackened nearly 500 square miles in Southern California, a large winter storm rolled in from the Pacific. In most places the rainfall was welcomed and did not cause any major flooding from burned or unburned hillslopes.

But in the town of Montecito, a coastal community in Santa Barbara County that lies at the foot of the mountains blackened by the Thomas Fire, a devastating set of sediment-laden flows killed at least 20 people and damaged or destroyed more than 500 homes. In the popular press these flows were termed "mudslides," but with some rocks as large as cars these are more accurately described as hyperconcentrated flows or debris flows, depending on the amount of sediment mixed with the water.

Birders Get a First Look at How 2017 California Wildfires Affected Wildlife

By Matt Blois

A neighbor knocked on Rick Burgess's door at about 9:30 p.m. to tell him a fire was coming towards his home in Ventura, California. When he looked outside he saw a column of smoke, and the hills were already starting to turn orange. He loaded up his truck with a collection of native plants he was using to write a countywide plant guide, and barely had enough time to get out.

Elon Musk's Brother Wants to Bring #RealFood to 100,000 Schools Across America

Kimbal Musk's nonprofit organization, The Kitchen Community, is expanding into a new, national nonprofit called Big Green, to build hundreds of outdoor Learning Garden classrooms across America.

Learning Gardens teach children an understanding of food, healthy eating and garden skills through experiential learning and garden-based education that tie into existing school curriculum, such as math, science and literacy.

Rover Pipeline Spills Another 150,000 Gallons of Drilling Fluid Into Ohio Wetlands

Energy Transfer Partners' troubled $4.2 billion Rover pipeline has spilled nearly 150,000 gallons of drilling fluid into wetlands near the Tuscarawas River in Stark County, Ohio—the same site where it released 2 million gallons in April.

The 713-mile pipeline, which will carry fracked gas across Pennsylvania, West Virginia, Ohio and Michigan and Canada, is currently under construction by the same Dallas-based company that built the controversial Dakota Access pipeline.

Large Dams Fail on Climate Change and Indigenous Rights

Brazil has flooded large swaths of the Amazon for hydro dams, despite opposition from Indigenous Peoples, environmentalists and others. The country gets 70 percent of its electricity from hydropower. Brazil's government had plans to expand development, opening half the Amazon basin to hydro. But a surprising announcement could halt that.

World's Largest Money Manager: Companies Must Respond to Social and Climate Challenges

The world's largest publicly traded companies must take a more active role in solving social issues or face blowback from investors, the CEO of BlackRock said Tuesday.

"To prosper over time, every company must not only deliver financial performance, but also show how it makes a positive contribution to society," Laurence Fink wrote in his annual letter to CEOs of companies in which BlackRock invests. BlackRock is the world's largest money manager, with more than $6 trillion in assets.
