# Asynchronous API Since satellites are not visible to ground stations 100% of the time, at times, there can be a significant delay in executing a user request. Therefore, the satellite API is asynchronous. Functions return a request object, which you can query for the request completion status by calling the `.status()` method. The request status will remain `Pending` as long as the satellites are out of reach of any ground station. As soon as it is executed, the status will switch to `Ready`. The user can then safely call the `.result()` method to obtain the satellite response.
