Fun with a new image data set: Mars Orbiter Mission's Mars Colour Camera

Emily Lakdawalla • October 06, 2016

It's always a delight to sink my teeth into a new data set, and I have spent this week playing with one I've been anticipating for a long time: ISRO's Mars Orbiter's Mars Colour Camera, or MCC. MCC is unique among current Mars cameras in its ability to get color, print-quality, wide-angle, regional views of Mars.

Where to find rapidly released space image data

Interested in playing with recent space image data? Here's a list of places to get the freshest photos from space.

Cassini's camera views of Titan's polar lakes in summer, processed into pseudocolor

Emily Lakdawalla • September 12, 2016

Titan's north polar lakes are well-lit by summer sun in these recent Cassini images. Image processing enthusiast Ian Regan shares his recipe for processing the longer-wavelength Titan images into visually pleasing "pseudocolor."

Hubble Series 1: How to Find Hubble Data

Judy Schmidt • August 02, 2016

Processing Hubble data presents a host of challenges, and the first of these has nothing to do with processing at all.

WISE Views in Infrared

Judy Schmidt • June 24, 2016

Amateur image processor Judy Schmidt explains the process of creating gorgeous views of the cosmos from infrared data from the WISE telescope.

What to expect from JunoCam at Jupiter

Emily Lakdawalla • June 09, 2016

Juno will go in to orbit at Jupiter on July 5 (July 4 in North and South American time zones), and it's carrying a camera that's going to take really awesome photos of Jupiter. But you're going to have to be patient. Emily Lakdawalla explains why.

A feast of new OSIRIS photos from comet 67P

Future High-Resolution Imaging of Mars: Super-Res to the Rescue?

Alfred McEwen • April 29, 2016

HiRISE Principal Investigator Alfred McEwen explains an imaging technique known as Super-Resolution Restoration (SRR), and how it could come in handy for high-resolution imaging of the Red Planet.

NASA Space Apps Challenge: Women hacking space image data

Emily Lakdawalla • April 22, 2016

Today I'm participating in a program called the International @SpaceApps Women in Data Bootcamp. I'm presenting a brief talk highlighting the way that my personal discovery of NASA's image data archives shaped my path into public communication about science, and briefly showcasing three other women who do amazing work with public image data.

Synthesizing DSCOVR-like Images Using Atmospheric and Geophysical Data

Steve Albers • April 20, 2016

Why does our planet look the way it does from space? How does light interacting with land, clouds, water, snow, ice, gases, and various aerosols all come together? One way to learn the answer is to try and synthesize DSCOVR's view from various "building blocks" of geophysical and atmospheric data.

A new angle on Mars for Mars Odyssey

Emily Lakdawalla • April 19, 2016

Mars Odyssey has been in space for 15 years. It flies in a special "sun-synchronous" orbit, crossing the equator at roughly the same local time every day. Over time, the Odyssey mission has changed what that local time of day is, and I just realized something cool about how those changes show up in the geometry of its images.

Brittney Cooper and Christina Smith and John Moores • April 07, 2016

Huygens may have landed on Titan over a decade ago, but a group of researchers from York University were able to make a new and unexpected discovery with this older dataset.

A Sunset on Mars: Crafting a scene from archival data

Justin Cowart • March 08, 2016

Ever wanted to stand on Mars and watch a sunset? Unfortunately for many of us, it will never be something that we get to experience in person. But thanks to our robotic emissaries on Mars, and some careful processing of images from NASA's Planetary Data System, we can get a sense of what it’s like.
