Worth the wait: First public release of Rosetta science camera images of comet 67P

Emily Lakdawalla • December 17, 2015 • 4

Finally! It has been a long wait, but so worth it: the Rosetta OSIRIS science camera team has delivered the first pile of data from the rendezvous with comet 67P to ESA's Planetary Science Archive. I have spent a good chunk of the last three days playing with the data, and it's spectacular.

A Rosetta OSIRIS picture of comet 67P that's only hours old

ESA announced today a new website at which the OSIRIS team will now be releasing images on a regular basis -- at least one per week -- and they will be recent. Even better news, all OSIRIS data taken through September 16, 2014 has been handed to ESA and its release is expected next week.

DPS 2015: A little science from Rosetta, beyond perihelion

Emily Lakdawalla • November 18, 2015 • 2

Updated numbers for physical properties of the comet, and a few interesting images of surface features and surface changes on Churyumov-Gerasimenko.

ESA mission updates

Emily Lakdawalla • November 04, 2015

There have been several important pieces of news about European missions in the last month: Rosetta's fate has been determined; ExoMars Trace Gas Orbiter's launch is slightly delayed; and they have selected a landing site for the ExoMars rover.

How the duck got its neck: Rapid temperature changes from self-shadowing may explain 67P's unusual activity and shape

Emily Lakdawalla • September 11, 2015 • 5

When Rosetta approached comet Churyumov-Gerasimenko last summer, both its shape and its activity were surprising. It looked like two comets welded together at a skinny neck. A new paper explains how the neck may be steepening itself.

Aluminum Shapemodel of Comet 67P

Mattias Malmer describes his MacGyver-esque process in creating a homemade aluminum version of 67P/Churyumov–Gerasimenko.

ESA's cool new interactive comet visualization tool based on amateur imaging work with open data

Emily Lakdawalla • August 13, 2015 • 2

A terrific new visualization tool for comet 67/P Churyumov-Gerasimenko demonstrates the value of sharing mission image data with the public. The browser-based tool lets you spin a simulated 3D view of the comet. It began with a 3D model of the comet created not by ESA, but by a space enthusiast, Mattias Malmer.

What's up in solar system exploration: August 2015 edition

Emily Lakdawalla • August 10, 2015 • 5

I'm back from two weeks' vacation, so it's time to catch up on the status of all our intrepid planetary missions, from Akatsuki to the Voyagers and hitting the Moon, Mars, asteroids, comets, and Saturn in between.

New Robotic Spacecraft Posters

Another round of posters to celebrate historic planetary missions.

Two more brief mission updates: Philae makes contact; Akatsuki to perform course correction

Emily Lakdawalla • July 10, 2015 • 6

As a followup to yesterday's post about Dawn, Juno, and OSIRIS-REx, I have updates on two more missions. With this post, I hope to have cleared the decks so that I can focus on Pluto for the next week!
