Rosetta end-of-mission update

Emily Lakdawalla • September 09, 2016 • 5

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

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 • 6

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 • 3

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 • 13

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 • 4

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 • 11

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 • 1

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 • 2

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.
