We could put humans on Mars in 5 years — if we’re willing to pay for it

Noam Hassenfeld is the host and senior producer of Unexplainable, Vox’s science podcast about everything we don’t know. He co-created the show and also composes the music.

After President Donald Trump revealed his budget proposal Monday, NASA had a forward-looking event of its own. The agency plans to build a space station orbiting the moon, send humans back to the moon by 2028, and eventually send them all the way to Mars.

NASA has been exploring Mars for decades with rovers, but Ellen Stofan, the director of the National Air and Space Museum and the former chief scientist of NASA, says that the only way to fully explore Mars is to send humans.

We talked with Stofan on the latest episode of Today, Explained, where she discusses NASA’s strategy on Mars, its relationship with Elon Musk, and its dreams of far-away space exploration.

You can listen to the full episode here, or on Apple Podcasts, Spotify, Stitcher, or Google Podcasts.
