Welcome to BlueSky! I’m Kevin, a software and spaceflight operations engineer at NASA/JPL.

I’m also an expert in planetary image processing and have worked with a number of missions both professionally and as citizen science.

I’ll share space imagery and art as I process it!

I left my heart in San Francisco.

And I have returned to seek my revenge and get my heart back!

All right, stop whatcha doin' 'cause I'm about to ruin
The image and the style that ya used to
I look funny, but, yo, I'm makin' money, see
So, yo, world I hope you're ready for me
Now gather 'round, I'm the new fool in town
And my sound's laid down by the Underground…

A very close view of the craters that cover the surface of Saturn’s icy moon Rhea. NASA’s Cassini mission made this flyby in January 2011, passing within 76 kilometers (47 miles) at a speed of 8 km/sec (18,000 mph). This image had a resolution up to 22.6 meters per pixel towards the closer terrain.

Learned how to do proper focus bracketing on my camera and took some new pictures of some actinolite schist and serpentine rocks I found recently.

HiRISE Image of Exocomet 3I/ATLAS!

On 2 October 2025, MRO turned away from Mars to image 3I/ATLAS, only the third interstellar object ever observed passing through our solar system!

Had to learn about the phenomenon of Crystal Twinning to answer why this oligoclase crystal was only reflective on one side at a time.

This is in a chunk of granodiorite found near Alta Dena, CA.

Only the right side of that crystal is reflecting light despite the shared surface being nominally flat A white with black spot rock with an elongated crystal in it.

In June 2017, immediately following passage low above the cloudtops of Saturn, Cassini used its Cosmic Dust Analyzer instrument on a study of the rings. Because their pointing matched, the cameras were able to take one of humanity’s first views from inside the vast ring system.

Green crystal in serpentinite found nearby. Just serpentine? Williamsite? Actinolite?

IRIDESCENT CLOUD ON MARS

Iridescent clouds over Gale Crater (enhanced color) - From Simeon Schmauß (stim3on.bsky.social) - https://flic.kr/p/2qJvryP
This enhanced color panorama was taken by Curiosity's Left Mastcam after sunset on Sol 3724 (27 January, 2023). It shows an iridescent high altitude cloud, likely made from CO2 ices. The sun has already set on the ground, but continues to illuminate this cloud which is likely at 60-80km altitude. The iridescence (rainbow effect) is caused by diffraction at sub µm ice particles. More information: doi.org/10.1029/2024GL111183 This panorama was stitched from 14 MAST_LEFT images from the PDS. The individual images were color calibrated to approximate what the human eye would see. The panorama was further enhanced to emphasise cloud structure and subtle color variations. See here for an unenhanced variant of the panorama: flic.kr/p/2qJwraX LMST: Sol-03724M18:52:13 Sun: Az: 276.2 deg, El: -5.9 deg Rationale: Characterize potentially iridescent ice clouds in twilight Credit: NASA/JPL-Caltech/MSSS/Simeon Schmauß

I was actually able to get a few shots of last night’s aurora!

I drove up to Castaic (northern Los Angeles County) with the family to find a darker sky. Couldn’t see much but the camera did.

I thought I was pretty good at youth sports photography. My 14 y/o daughter picks up my camera for the first time at a game this morning and just schools me.
