A deep dive into the highest-resolution Voyager Jupiter data

Björn Jónsson • September 14, 2016

A few weeks before the first Juno high resolution imaging, I decided to take a look at Voyager color images at various resolutions, with particular attention to high-resolution mosaics.

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."

Rosetta end-of-mission update

Emily Lakdawalla • September 09, 2016

The European Space Agency has shared plans for the end of the Rosetta mission scheduled for September 30, just three weeks from now. The landing site will be located on the "head" of the comet, next to a prominent pit now named Deir el-Medina.

Philae spotted on the surface of comet Churyumov-Gerasimenko

Emily Lakdawalla • September 06, 2016

Ever since its landing, Philae has been elusive. It went silent just three days later and never returned any more science data, though it made brief contact with the orbiter last summer. Now, just a month until the planned end of the Rosetta mission, the orbiter has finally located the lander in a stunning high-resolution view of the surface.

OSIRIS-REx is on the launch pad, ready for the big day

Emily Lakdawalla • September 02, 2016

The OSIRIS-REx mission passed its flight readiness review yesterday, clearing the way for the spacecraft to launch on Thursday, September 8. Here's a schedule of next week's NASA TV briefings and a photo album of the launch preparations.

Juno's instruments return riches from first perijove

Emily Lakdawalla • September 02, 2016

On August 27, Juno soared across Jupiter's cloud tops from pole to pole, with all instruments operating. NASA posted some terrific first results from several of the instruments today. And the JunoCam team released all 28 raw images taken during the close encounter.

Juno's first Jupiter close approach successful; best JunoCam images yet to come

Emily Lakdawalla • August 27, 2016

NASA announced this afternoon that Juno passed through its first perijove since entering orbit successfully, with science instruments operating all the way. This is a huge relief, given all the unknowns about the effects of Jupiter's nasty radiation environment on its brand-new orbiter.

How big is that butte?

Emily Lakdawalla • August 23, 2016

Whenever I share images from Curiosity, among the most common questions I’m asked is “what is the scale of this image?” With help from imaging enthusiast Seán Doran, I can answer that question for some of the Murray buttes.

JunoCam "Marble Movie" data available

Emily Lakdawalla • August 22, 2016

Since a few days after entering orbit, JunoCam has been taking photos of Jupiter every fifteen minutes, accumulating a trove of data that can be assembled into a movie of the planet.

JunoCam raw data from the Juno approach movie

Emily Lakdawalla • August 09, 2016

As it approached Jupiter from June 12 to 29, JunoCam captured an animation of the major moons orbiting the planet. The mission released a processed version of the animation on the day of orbit insertion, but took a few weeks to release the raw image data. I've prepared a page hosting all the raw data, and share a few processed versions.

Rosetta end-of-mission plans: Landing site, time selected

Emily Lakdawalla • July 26, 2016

ESA's comet-chasing Rosetta spacecraft is nearing the end of its mission. Last week, ESA announced when and where Rosetta is going to touch down. And tomorrow, it will forever shut down the radio system intended for communicating with the silent Philae lander.

Jupiter's Clouds: A Primer

Justin Cowart • July 08, 2016

With Juno arriving at Jupiter, Justin Cowart gives us a lesson on the giant planet's varied cloud patterns.

A peek at the JunoCam approach movie

Emily Lakdawalla • July 04, 2016

We're now just about 12 hours away from Juno's Jupiter orbit insertion. As anticipation ramps up, NASA has released this sneak peek at JunoCam's approach movie, made of views of Jupiter and its largest moons shot during the final approach, up until about five days ago.

Juno's first taste of science from Jupiter

Emily Lakdawalla • June 30, 2016

Jupiter is growing in Juno's forward view as the spacecraft approaches for its orbit insertion July 5 (July 4 in the Americas). The mission has released images from JunoCam and sonifications of data from the plasma waves instrument as Juno begins to sense Jupiter.

Big booster blasts Utah hillside, and NASA discusses Journey to Mars

Jason Davis • June 28, 2016

NASA and Orbital ATK successfully completed a qualification motor firing of a five-segment solid rocket booster that will fly on the Space Launch System in 2018.

Quick multimedia roundup: China's new rocket blasts off on inaugural mission

Jason Davis • June 25, 2016

China's new Long March 7 rocket successfully blasted off on its inaugural mission today at 8:00 p.m. Beijing time (12:00 UTC, 7:00 a.m. EDT).

National Selfie Day: Spacecraft self-portraits

Emily Lakdawalla • June 21, 2016

It's apparently National Selfie Day. I'm not entirely sure who has the authority to declare these things, or why they decided we needed a National Selfie Day, but since the self-portrait is one of my favorite subgenres of spacecraft photography, I couldn't resist writing about them.

Multimedia roundup: Blue Origin completes two-parachute test flight

Jason Davis • June 20, 2016

Yesterday in West Texas, Blue Origin launched its New Shepard spacecraft on its sixth suborbital test flight. The capsule normally descends using three parachutes, but on Sunday, just two were used to show the spacecraft could still land safely in the event of a parachute mishap.

Picture-perfect landing for Soyuz crew on sunny Kazakh steppe

Jason Davis • June 18, 2016

Tim Kopra, Tim Peake and Yuri Malenchenko are back on Earth this morning following a picture-perfect landing on the sunny Kazakhstan steppe.

Three bright planets: Portraits from the Pyrenees

Emily Lakdawalla • May 26, 2016

It's a great time to go outdoors and look at planets. I have three glorious planetary portraits to share today, sent to me by amateur astronomer Jean-Luc Dauvergne.
