In the year 2500, the Callisto family, composed of the character of Miles, his sister Loretta, and their scientist parents Phoebe and Leo, works for the Tomorrowland Transit Authority (TTA), to connect the universe.

Nancy Kanter said "We hope this series will influence a child's interest in science and technology by introducing them at an early age to the exciting world of space exploration, how things work and what lies beyond the here and now.

Yes, it's a bit creepy to think of two children being raised in the claustrophobic confines of a four-person spaceship, home schooling taken to an extreme.

But the show is fast-moving enough to keep young viewers interested... and it's not shy about putting Miles and Loretta in gently life-threatening predicaments.

"[34] Rob Owen of the Pittsburgh Post-Gazette said "Miles from Tomorrowland has some real science facts threaded through it- there's mention of Jupiter's moon lo in an early episode- but given how these factoids sit side-by-side with the science fiction gadgets and spaceships, its unclear what positive educational impact their inclusion will have."

"[35] Emily Ashby of Common Sense Media have the series a grade of four out of five stars, praised the depiction of positive messages and role models, saying that Miles from Tomorrowland challenges traditional gender roles and promotes work ethic, while noting the presence of educational value regarding the vocabulary dealing with space.

According to a press release by Disney–ABC Television Group using data from Nielsen,[39] across Q3 of 2015 (6/29 through 9/27), Miles from Tomorrowland was the fourth highest-rated series across preschooler-dedicated TV networks in the US with 653,000 total viewers ages 2+ who watched the show on Disney Junior.

This ranking was surpassed only by PJ Masks (767,000), Sofia the First (667,000), and Mickey Mouse Clubhouse (666,000), all Disney Junior shows as well.
