Include at least one site (two maximum) you would like to have acquired to help support your research or test your conclusions. Provide detailed information to help ensure that your request can be considered and included in the Crew Earth Observation target list sent to astronauts onboard the ISS. If two sites are requested, please indicate which is the higher priority by checking the appropriate box.Note: ISS operates between 51.6°S and 51.6°N. Any latitude coordinates to the north or south of those coordinates will result in obliquity and degradation of image features. It is advised to keep your site request between 53°S and 53°N, especially when requesting imagery of small features.Higher Priority Request:Request 1Request 2
