Ever wonder how space & art combine to transform raw, noisy images captured by spacecraft into beautiful, clean images for us to see here on Earth? In this week's episode, @emilyolsen.bsky.social & @alexaerdogan.bsky.social talk to @jpmajor.bsky.social about image processing. www.artastra.space

The leading face of Saturn's moon Helene in a color-composite made from image data acquired by NASA's Cassini spacecraft on June 18, 2011. Helene is small—only 43.4 kilometers across at its widest. The streaks are downslope flows of icy dust.

Here's a view of Saturn's egg-shaped, ~4-km-long icy fluffball moon Methone (pronounced meh-tho-nee) imaged with NASA's Cassini spacecraft on May 20, 2012 from 4,453 km away.

A view of Mars made from images captured with the EXI camera aboard UAE's Hope Mars Mission orbiter on August 12, 2023 from a distance of about 20,500 km. The small dark spot in the center near the top is Phobos, which happened to be passing between the spacecraft and Mars at the time.

NASA's Perseverance rover on Mars (left edge) captured with Ingenuity's camera from about 200m away on April 23, 2023 during the helicopter's 51st flight.
This is a crop and color process of the original Ingenuity image file mars.nasa.gov/mars2020/mul... (thus the noise and low resolution)

Here's a view into the 1900-km-wide vortex of clouds swirling over Saturn's north pole; a color-composite made from images captured with Cassini's narrow-angle camera ten years ago today—April 2, 2014—from a distance of 2.2 million km.

Here's a view of the Apollo 11 landing site with the LM descent stage casting a shadow toward Little West crater, imaged with the Orbiter High Resolution Camera on India's Chandrayaan-2 from an altitude of 100 km (62 miles) on April 2, 2021.

The Moon 🌓 tonight and the ISS, captured in two separate photos taken with a Nikon D810 and Sigma 150-600 C lens (w/1.4x teleconverter) from my front yard. (I went out to shoot the Moon; the ISS was just a nice surprise. Decent capture too I think!)

Apollo 9 CM Pilot Dave Scott taking a moment to enjoy a view of Earth from the open hatch of the CSM Gumdrop, at the time docked to the LM Spider and orbiting Earth at an altitude of about 149 miles on March 6, 1969. From original NASA image AS09-20-3065

14 years ago today, on March 1, 2010, NASA's Mars rover Spirit captured this view comprising its final pancam images showing one of its wheels stuck in soft sand around an area in Gusev Crater called Home Plate. Communication from Spirit ended 3 weeks later.

Here's a view of the Odysseus lander's broken leg lying on the surface of the Moon awash in the glare of sunlight—an edited crop of an image originally captured by Hawai'i's International Lunar Observatory Association's onboard ILO-X camera on February 25, 2024.

The first images of Mimas' Herschel crater weren't received until 1980, so the resemblance is purely coincidental.

Here's a crop of that first one using a higher-resolution version, white-balanced and level adjusted. I love the cratered lunar surface visible below the flying dust and rocks!

Today the Intuitive Machines team shared two new pictures from the NOVA-C Odysseus lander: one showing the moment of touchdown near the Moon's south pole with the descent engine firing and another showing the lander's final orientation tipped over sideways after one of the legs broke during landing.

This is a view of JPL's Ingenuity helicopter at its final landing site on a sand dune captured with Perseverance's SuperCam science camera on February 25 (sol 1072). Cropped, upscaled and adjusted to approximate natural color. You can see how one half of the top rotor wing is basically missing.

I heard there was a large sunspot visible today so I took my camera out to see. There sure is! Here's the Sun this afternoon with active region 3590, captured with a 600mm lens and white light filter.

The true reason why Einstein was history’s greatest physicist
Einstein had an incredible and scientifically prolific life.
But there's one advance, generally, that places him leaps and bounds above all others, even in the minds of most physicists.

This is the star-forming region S106, 3,300 light-years away, in a color-composite I made from images captured with Hubble in infrared light on February 13, 2011 for astronomer Keith Noll. A newly-ignited star is blasting away parts of the cloud of dust and gas from which it formed.

If you're looking for something to watch this weekend, I highly recommend The Platypus Guardian on PBS Nature. I watched it last night and it was really good. A bit emotional at times but I like that. Well done, and what a fascinating animal. www.pbs.org/video/about-...

Here's Saturn's funky little moon Hyperion in a color-composite made from images captured with Cassini on August 25, 2011 from a distance of about 53,000 km. Hyperion is around 260 km wide and 360 km long. It has a very low density and "spongy" surface texture. It's weird and I like it.

My favourite thing about the astronomy community on Bluesky is that I feel we're much closer to amateur astronomers here. Which is *awesome*, because so many people take such incredible photos!

Now I'm wondering if they at least had newer EMUs toward the end of the Shuttle program than near the beginning (like, 1984)

"NASA performs ground maintenance on each EMU after 6 years on-orbit or 25 EVAs, whichever comes first." Huh. OK, wasn't aware of that! A little unnerving, I'd think (especially considering some of the leak issues that Luca Parmitano ran into.)

Here's a photo of NASA astronaut Bruce McCandless during his MMU EVA during STS-41B on February 7, 1984. I like this one because he looks like he's having a good time out there, 300 feet away from the Challenger shuttle.
