DESIGNED FOR EVERYDAY EXPLORATION
Astra is available for iPhone and iPad. Location is optional, and no account is required. The animated satellite is an artistic visualization inspired by the Lunar Reconnaissance Orbiter; it is not live mission telemetry. Astra is independent and is not affiliated with or endorsed by NASA.
Lunar values are estimates for education and general observation, not navigation or professional scientific planning.
