These are some of the reasons why your Mission Space Lab experiment idea may have been rejected.
Use of thermal camera
Your experiment idea used the IR camera incorrectly. The camera is not capable of thermal imaging. Any experiments submitted that require thermal imaging will sadly not be able to achieve flight status.
Your experiment idea requires interaction with crew members. Unfortunately, the ISS astronauts are very busy and do not have the time to actively participate in the Astro Pi experiments.
Relies on specific event occurring
Your experiment idea relies on a specific event occurring which is unlikely to occur in the 3 hour period in which your experiment will run.
Relies on ISS passing over a specific feature
Your experiment idea relies on the ISS passing over a specific feature. This is unlikely to occur in the 3 hour period in which your experiment will run.
Not enough detail
Your experiment idea was unclear and didn’t provide enough detail. Sadly we cannot progress entries through to Phase 2 without understanding the basis of your experiment idea.
Requires extra kit/stuff
Your experiment requires extra materials not available on the ISS.
Requires images from Astro Pi Ed
Your experiment idea asked for images to be retained from Astro Pi Ed. This is against programme rules as we need to protect the privacy of the astronauts.
Will exceed disk quota
Your experiment idea is likely to exceed the disk quota. You should modify your experiment so that no more than 3GB of data will be produced in a 3 hour period. Any experiment that exceeds the disk quota will not be able to achieve flight status and will be disqualified. Requires code to run at a known time.
Requires code to run at a known time
Your experiment idea relies on your program running at a specified time. This is not possible and sadly will not be able to achieve flight status.
Requires real-time communication with the Astro Pi units
Your experiment idea required real time communication between or with the Astro Pis.
Your experiment idea required night time photography. We have recently conducted some tests and have concluded that the current hardware is unable to capture images with enough light to produce results.
