Growney Space

Fly to the Sun and all eight planets with Growney, a little astronaut who reads everything aloud.

Growney Space is an illustrated space encyclopedia for children. Every planet is an expedition:

• Land the capsule and look around a hand-drawn landscape. Tap the seeds to find the wonders hidden there: a volcano more than twice as tall as Everest, a blue sunset on Mars, ice in Mercury's dark craters.
• Jump in the lab and see how high you would jump on Mars or Jupiter, and how much you would weigh there.
• Spin a globe with your finger and visit real places, with real photos.
• Leaf through an album of real space photos, sounds and films.
• Pass the astronaut exam and earn a stamp in your space passport.
• Play a mini game on every world: land a rover on Mars, ride Jupiter's winds, dive through Saturn's rings, slingshot a probe all the way to Neptune.

Made for children who are only learning to read: Growney reads the texts aloud in English, Polish or Ukrainian.

Safe and calm:
• No ads, no purchases, no tracking.
• Works without an account. A parent can sign in with a Growney account to keep the child's finds and stamps on every device.
• Links and settings for grown-ups are behind a parental gate.

Every fact is checked against NASA and other sources. Photos: NASA/JPL-Caltech and others. Growney Space is not affiliated with or endorsed by NASA.

On first launch the child picks a language, and Growney's voice in it downloads once (about 118 MB).

Recent changes:
Six new stories in the hangar. Meet the Ingenuity helicopter on Mars, the lunar rover, Starship, SLS and Orion, the satellites around us and the Parker probe. Each has its own games, real photos and an engineer's exam, all voiced in English, Polish and Ukrainian.
