The Astrosmurf (original French title Le Cosmoschtroumpf) is the sixth album of the original French-language Smurfs comic series created by Belgian artist Peyo.

[2] There is a smurf who wants to travel to outer space, so he tries to build a rocketship, but it fails to get off the ground and so he grows moody and depressed.

After that, the smurfs dismantle the ship and take it to a volcano, where they disguise themselves as aliens named "Swoofs", so Astrosmurf believes he has arrived to another planet.

Poet Smurf stays in the village to compose an ode to the Sun, while Farmer Smurf also stays, upset because the sun will dry his crops, so he decides to use the machine to make rain.

When it rains, Poet Smurf uses the machine to have sun, then Farmer Smurf uses it to have rain, and so on, til the machine's controls break and it begins to make sudden weather changes (snow, winds, storms).
