Juno's Perijove-28 Jupiter Flyby, Reconstructed in 125-Fold Time-Lapse

Quote:
On July 25, 2020, NASA's Juno probe successfully performed her Perijove-28 Jupiter flyby.

The movie is a reconstruction of the 2 hours and 45 minutes between 2020-07-25T05:30:00.000 and 2020-07-25T08:15:00.000 in 125-fold time-lapse.
It is based on 38 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.

Like for all its previous flybys, Juno approached Jupiter roughly from north, and left Jupiter looking towards the soutern hemisphere. Closest approach to Jupiter was 3,500 km above the nominal IAU 1-bar level, and near 25.3 degrees north (planetocentric), according to long-term planning of November 2017.

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.

Humpback Whales make a "bubble net" to capture krill.

I knew about this, but had never seen it from that angle. I though whales did a circle, but it's a spiral!?

Look again

I mean, it's still a striking pose, but a different one than you may have seen the first time.

I doubt it, but obviously it will help you get a nut.
