One of my most popular projects which I never made a video of is the #raspberrypi#pico based digitally controlled oscillator originating on the design of the Roland #juno. It uses accurate #pio for driving up to six independent voices and is controlled by #midi. Also a few parameters can be changed by its built-in #adc. See https://github.com/polykit/pico-dco for more details #dco#synthesizer#synthdiy#kicad
Jupiter as it appeared yesterday to the Juno spacecraft as the orbiter approached its 54th science flyby (“Perijove”). You’re seeing the mid-northern latitudes with the equator on the left limb of the planet, and North to the right.

Cet été, j'ai eu la chance de visiter le JPL, ce centre de la NASA où sont conçues, assemblées et testées la plupart des sondes et rovers américains qui explorent le Système solaire. Un récit de ma visite pour vous emmener dans cet endroit mythique. 1/37 @nasajpl@NASA#NASA#JPL
There are waves on Jupiter, but not exactly the kind surfers can ride. These plasma waves are much more intense than anything that crashes onto a beach....

La sonde #Juno a survolé la lune #Io de #Jupiter le lundi 31 juillet vers 05h00 UTC à une distance d’environ 22 000 km. Voici une animation de 12 images de la caméra Junocam par Jason Perry. #espace#exploration#NASA
🛰️🟠 La sonde #Juno de la #NASA va effectuer son 53e survol de #Jupiter (Perijove 53) ce lundi 31 juillet à 09h10 UTC.
Quelques heures plus tôt, vers 05h00 UTC, elle a survolé la #Io à une distance d’environ 22 000 km, le plus proche survol de la lune galiléenne à ce jour. #espace#exploration
Launched in 2011, the Juno spacecraft is performing far beyond its original mission objectives. It entered Jupiter’s orbit in July 2016 and was expected to perform 36 science orbits around Jupiter and end the mission in early 2018. Instead, it has performed 50 longer-period orbits and will continue its extended mission at least until Sep. 2025.
The graphic below shows the original Juno mission orbits.
Juno's primary mission ended in July 2021. The mission was then extended until 2025, with 42 additional orbits, including close passes of Jupiter’s north polar cyclones; flybys of Ganymede, Europa, and Io; as well as the first extensive exploration of the faint rings encircling the planet.
The later orbits spend more time inside Jupiter's ferocious radiation belts, risking damage to spacecraft electronics.
Here are a subset of the dates for the next set of Jupiter flybys by Juno.
Perijoves 53, 55, 57 and 58 will feature close flybys of the moon Io; Juno will be just 1,500 km from Io's surface during PJ57 and PJ58!
Juno orbital period = 38 earth days.
Io orbital period = 42.5 hours (1.77 days).
Juno gets close to Io on every alternate orbit.
Juno orbital period after PJ57 will be 33 days, allowing it to visit Io on PJ58.

Io is a world tormented by active lava-spewing volcanoes, as it is stretched and squeezed by the gravitational forces of Jupiter, and the moons Europa and Ganymede.
This pic taken by JunoCam from 35,600 km on May 16 during PJ51 indicates changes at the Volund region, where the lava flow field has expanded to the west and another volcano just north of Volund has fresh lava flows surrounding it.
During the Juno flyby of Io, all instruments will be active, including JunoCam, the visible light camera and JIRAM, the Jovian InfraRed Auroral Mapper.
JIRAM's ability to image and take spectra in the 2-5 μm wavelength range will prove to be very valuable in mapping Io's fiery landscape.
The IR image of Io below is based on JIRAM data taken on July 5, 2022 from 80,000 km away. The bright spots highlight active volcanoes that dot the moon.
The video below exemplifies the capabilities of the Juno JIRAM instrument.
JIRAM, developed by the Italians, contains an imager at 3.45 μm and 4.78 μm wavelengths and a spectrometer that covers infrared 2-5 μm range.
The video is based on data from JIRAM PJ4, which is used to map the temperature of Jupiter’s atmosphere over its north pole and provides insight into how the powerful cyclones at Jupiter's poles work.
The NASA Juno spacecraft is swinging around Jupiter, having made its closest encounter an hour ago during Perijove 53, and is headed back out into its 38 day orbit.
Images from the 53rd flyby of Jupiter by the Juno spacecraft have already been posted at the NASA Juno site.
Here is one of the pics of the ever changing face of Jupiter, with some amateur level processing by me.
Look for high quality processed images at the website and from experts here like @kevinmgill@andrealuck@spacegeck
We cancelled all of our #streaming to support the #WGAstrike, & are uncovering a long-ignored trove of DVDs & VCR tapes (we have a working VCR!).
Last night was #Juno w/Elliot Page. Tonight, one of my all-time favorites: #RubyInParadise w/Ashley Judd.
Respect to workers whose labor opened up a wider, wilder world for me, evoked sympathy & understanding for new people & cultures, made me laugh, gave new ideas & taught history & compassion.
