On May 19, 2017, NASA's Juno probe successfully performed her Perijove-06 Jupiter flyby.

The movie is a reconstruction of the 5.5 hours between 2017-05-19T03:30:00.000 and 2017-05-19T09:00:00.000 in 125-fold time-lapse.

It is based on 39 of the JunoCam images taken, and on spacecraft trajectory data provided via SPICE kernel files.

In steps of five real-time seconds, one still images of the movie has been rendered from at least one suitable raw image. This resulted in short scenes, usually of a few seconds.

Playing with 25 images per second results in 125-fold time-lapse.

Resulting overlapping scenes have been blended using the ffmpeg tool.

In natural colors, Jupiter looks pretty pale. Therefore, the still images are approximately illumination-adusted, i.e. almost flattened, and consecutively gamma-stretched to the 4th power of radiometric values, in order to enhance contrast and color.

Juno approached Jupiter from the northern hemisphere, then flew almost exactly over its north pole, came rapidly closer to Jupiter until a few thousand kilometers north of Jupiter's equator, then, after closest approach, started to recede again, and left Jupiter looking towards the southern hemisphere. Closest approach to Jupiter was 3,496 km above the nominal IAU 1-bar level, and near 5.6 degrees north (planetocentric).

JunoCam was built and is operated by Malin Space Science Systems in San Diego / California / USA.

Many people at NASA, JPL, SwRI, and elsewhere have been, are, and will be required to plan and operate the Juno mission.
