Five young astronauts arrive at the ISS Curiosity in 2045 and learn the basics of space science — from gravity and photosynthesis to radio waves and asteroids. Each episode ends with a calming stargazing moment.

The five kids arrive at the ISS Curiosity. Everything floats — including Leo's lunch. They must secure the cargo bay before supplies drift into the airlock.

The oxygen recycler glitches. Priya uses the experimental greenhouse to boost oxygen while Leo fixes the machine, but plants grow differently in zero-G.

A solar flare knocks out communications with Earth. Mars overcomes his anxiety to calculate the right frequency for a makeshift antenna.

A small asteroid passes close enough to capture a sample. Nia's first real space rock contains an unknown mineral that reacts to heat.

The station's rotation module malfunctions, creating uneven gravity. Leo and Zara must recalibrate the spin while learning about centripetal force.

Everyone misses home. Priya realizes starlight is seeing the past. The crew sends video messages to their families and learns about the speed of light.
