On August 5, NASA’s Curiosity will makes its landing on Mars. The event will mark the end of the journey and the start of the mission of exploration for the Mini Cooper-sized rover. To help explain the descent and landing sequence, the space agency has once again tapped a Star Trek legend—William Shatner. It’s the continuation of a long-time relationship between Shatner and NASA, but this time they’ve also brought in the voice talents of another Trek icon, Wil Wheaton. In separate videos, the generation-spanning William and Wil take us through Curiosity’s “Grand Entrance” and its mission to find out if life ever existed on the Red Planet.
Watch the two videos below and let us know whose narration you like best.
