IMPORTANT: PLEASE READ FIRST
Children ask amazing questions. Why is the Sun so hot? What would happen if it disappeared? Space Mission turns those questions into games, so your child learns real space science while having fun. It suits ages 8 to 12, and the Cadet rank makes it easy for younger children aged 6 to 8.
Tap the 🔊 buttons to have questions and instructions read aloud for early readers. Nothing is read aloud unless you tap.
Save it to your home screen so Space Mission gets its own icon and opens like an app:
For a more natural reading voice, the 🔊 buttons use your device's own voice:
If the game is quiet: on an iPhone or iPad, check the device is not on silent. On an Android phone or tablet, press the volume up button while the game is open, because game sounds use the media volume.
Children can replay any game at any time. To clear all progress and start fresh (for example, for a new child on the same device), tap below. This removes all stars, patches, unlocked missions and finished jigsaws on this device.
Talk about the facts together. Ask your child which answer surprised them most, or go outside together and watch how your shadows change length during the day. New missions for the planets, stars, black holes and more are on the way.
A Billion Whys: Space
300 real questions kids ask, answered in clear, friendly language and checked against the latest information from NASA and other trusted sources. In full color, for ages 6 to 12.
