It’s a race to Mars for Elon Musk.

“You want to be inspired by things,” the SpaceX CEO told an audience of several thousand upon arriving on stage at the 2017 International Astronautical Congress in Adelaide, Australia. “It’s about believing in the future and believing the future is better than the past, and I can’t think of anything more exciting.”

Musk provided an update to his vision last year of creating a permanent, self-sustaining human presence on Mars.

SpaceX aims to do 30 launches next year. According to Musk, there are about 60 launches each year, which means his company could account for half. This year, its completed 13 out of what Musk said on Friday was a goal of 20.

Last year, Musk laid out his plan to build a 42-engine rocket capable of holding around 100 people.

He said that Interplanetary Transport System will launch people to and from Mars. The booster system was referred to as the BFR.

The BFR is less expensive than the companies Falcon 1, Falcon 9 and Falcon Heavy rocket systems, according to SpaceX.

Musk said the revenue he’s seeing from launching satellites will pay for the costs of BFR.

In addition, Musk recently released a SpaceX space suit, which he says was engineered to handle double vacuum pressure.

SpaceX, which was first started in 2002, has been recently challenging Boeing and Lockheed Martin’s long-time monopoly over U.S. military launches. Earlier this year, SpaceX landed a $97 million contract to launch a military satellite.
