At 2:30 p.m. ET, the SpaceX founder and CEO will deliver remarks at the 67th International Astronautical Congress (IAC) in Guadalajara, Mexico. The livestream will be covered by YouTube and is embedded below for folks to see what Musk has to say about his plans to not only colonize Mars but also bring humans to places in the solar system beyond the red planet.

In a statement, the IAC said Musk’s keynote will be entitled “Making Humans a Multiplanetary Species,” and he 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.” He will also talk about how industries, scientists, and government can work together to build “architectures for colonizing the red planet.”

Musk has a full plate. In addition to his duties at SpaceX, he serves as the founder and CEO of electric car maker Tesla. He’s also involved in several other companies and initiatives across a slew of industries, including solar and artificial intelligence.

While Tesla (TSLA) has taken up a sizable portion of his time, space exploration has also been a focus. In addition to getting people to Mars, SpaceX has been involved in taking astronauts and supplies to space. The company is also working hard on a reusable rocket that cuts down on the cost to travel to space and could be a core component in ultimately getting people to space and Mars.

More recently, Musk’s focus has been on Mars. SpaceX, for instance, was able to fire for the first time its Raptor interplanetary transport engine on Monday. While it’s still far from being ready for Mars travel, it was an important step in the right direction. The Raptor could also prove to be important in a broader initiative by Musk to not only get humans to Mars but also explore further out into the solar system.

However, regardless of what Musk says about the challenges his company is facing, it will take time to achieve his grand ambitions. Currently, SpaceX is hoping to launch its first unmanned SpaceX mission in 2018 and get its first human mission off the launch pad in 2024.
