Stars, Moon and planets open imagery from the TUBIN small satellite mission

Pictures by TUBIN's VIS camera of the Moon (one including the Earth horizon), Jupiter and the stars. Infrared pictures are not part of this dataset. The pictures are zipped in tubin_deep_space_pictures.zip. Some pictures are in full resolution, some of them in lower resolution due to downlink constraints. Not all pictures contain usable features, for instance some stars images are too dark to detect any star. Most pictures contain a significant number of hot pixels. tubin_deep_space_pics_overview.csv contains an overview of the imaging campaigns that produced these images. The column format is the following: Column name Description Target Name of the celestial bodies targeted (e.g. Moon, Capella A, etc) Date Day of the imaging campaign Type Moon, Moon-Earth, Moon-Jupiter or Stars Pointing_Mode Pointing mode, either Inertial or Target. In the case of target pointing, the spacecraft attitude was not constant during the campaign Folder Name of the subfolder containing the campaign's images q_tod_from_sat_[s,x,y,z] Scalar-first, unit quaternion commanded to the spacecraft for each imaging campaign. This does not mean that this attitude was reached because of the pointing error The pictures have the following filename convention, e.g. TUBIN_VIS_20221118_134102_088_1.png : Name Description VIS Name of the camera 20221118 Day (%Y%m%D) 134102 Time of day (%H%M%S) 088 Milliseconds 1 Processing level: 1 is black-and-white, 6 is RGB Most PNG pictures have a JSON companion file containing the following metadata (not all metadata keys are described here): Name Description AdcsStateValid 1 if attitude knowledge information present in picture metadata, 0 otherwise AngularRate[X,Y,Z] Angular rate in SAT frame in deg/s Attitude[S,X,Y,Z] Scalar-first, unit quaternion representing the spacecraft quaternion q_TOD_from_SAT ExposureTime Exposure time in microseconds Height Height in pixels MjdUtc MJD UTC date in days OffNadirAngle Angle between camera boresight and nadir direction in degrees Position[X,Y,Z] Spacecraft cartesian position in TOD frame in meters RecordTime Timestamp string (might not be present in all JSON files, see note below) Velocity[X,Y,Z] Spacecraft cartesian velocity in TOD frame in meters/second Width Width in pixels Notes: a few pictures use an older JSON metadata format without RecordTime, with only MjdUtc in days. Use for instance astropy.time.Time(pic_meta["MjdUtc"], format="mjd").to_datetime() to convert this MJD UTC date to a python datetime object. some pictures do not have a JSON companion file at all. In this case, use TUBIN's AOCS telemetry instead to retrieve the position/velocity/attitude/rate data at the time of the picture: https://zenodo.org/records/19708907 TUBIN's VIS camera has the following specs: Name Value Model Onsemi MT9J003 Width 3664 Height 2748 Pixel pitch 1.67um Focal length 22.9mm Nominal mounting orientation in spacecraft q_SAT_from_CAM (scalar first, unit quaternion) [0.70710678, 0.0, 0.0, 0.70710678] For more information about the TUBIN spacecraft and for AOCS telemetry data, refer to https://zenodo.org/records/19708907
