The Rosetta Image Archive Is Now Complete and Freely Available, so You Can See a Comet Like Never Before

The European Space Agency’s Rosetta mission to the comet 67P/Churyumov-Gerasimenko was one for the ages, providing an unprecedented look at this oddly shaped celestial object. The Rosetta probe captured nearly 100,000 images over the course of its mission, all of which are now freely available to the public in a single Rosetta archive. Read More >>

Lost Japanese Spacecraft Has Made a Key Measurement on Rosetta’s Comet

Japan’s Proximate Object Close Flyby with Optical Navigation (PROCYON) has been lost in space ever since its ion thrusters blew out in 2014. Since then, the tiny spacecraft has done its best to be useful, orbiting the Sun by itself. A new study reveals the PROCYON made some impressive observations on Comet 67P/Churyumov-Gerasimenko, the same comet the Rosetta spacecraft observed for two years before ending its mission in 2016.

What Was the Rosetta Mission?

After two years of science, the European Space Agency’s Rosetta mission ended yesterday in a gentle crash-landing. But if you haven’t been tracking this spacecraft’s movements as obsessively as we have, you might be wracking your brain this morning trying to remember what the Rosetta mission was. Read More >>

All the Incredible Things We Learned From Our First Trip to a Comet

The historic Rosetta mission has finally come to an end. Over the past two years, the probe’s many instruments have scanned virtually every nook and cranny of this weirdly shaped rock, unleashing a treasure trove of new information about comets in general, and 67P/Churyumov–Gerasimenko in particular.When Halley’s Comet paid us a visit back in 1986, the European Space Agency’s Giotto spacecraft was sent to explore the incoming ball of ice and dirt. By the time the mission was over, it became glaringly obvious that if we were ever going to learn anything about comets, we’re going to have to get a bit closer. Like, a lot closer. Read More >>

We Now Know What Caused the Weird Erruptions Rosetta’s Comet

Last summer, something strange happened on Rosetta’s comet. After a period of calm, the comet began erupting, throwing huge jets of comet dust into space before abruptly stopping. Now, we finally know what happened. Read More >>

The Amazing Place the Rosetta Spacecraft is Going to Die

In two weeks, the European Space Agency will crash-land its prized Rosetta spacecraft, marking a dramatic end to the whirlwind two-year science mission that saw humanity’s first-ever comet landing. It’ll be 48 action-packed hours as Rosetta descends to its ultimate resting place on Comet 67P — and to get you properly excited for that event, we wanted to share the fascinating reason this site was chosen.

How Scientists Found the Tiny Philae Lander on a Giant Comet

In the shadow of a cliff on an icy rock 700 million kilometres from Earth, a washing machine-sized robot by the name of Philae has spent the last two years in hibernation. We’d already given up hope of speaking with humanity’s first and only comet lander ever again, and time was running out to catch a final, fleeting glimpse of the beloved craft. In the eleventh hour, science prevailed. Read More >>

The Date Has Been Set for Rosetta’s Mission-Ending Crash Into the Comet 

Set yourself a reminder for September 30th. That’s when the Rosetta spacecraft will make a controlled descent and crash on the surface of Comet 67P/Churyumov-Gerasimenko. After 12 years in space and nearly two years circling around this dusty, weirdly shaped comet, this historic mission is finally coming to an end. Read More >>

Scientists Confirm: Comets Smell Like Cat Piss

Rotten eggs, cat urine, bitter almonds — that’s the delightful elixir of aromas comprising the BO of one comet 67P, also known as Rosetta’s comet. In a heartwarmingly nerdy yet mildly alarming development, members of the Rosetta mission team have commissioned scent firm The Aroma Company to turn it into a perfume. Read More >>

Rosetta Finds Building Blocks For Life On Comet

Scientists have long debated the possibility that some of the key ingredients for life on Earth were brought to our newly-formed planet by comets and asteroids. A new discovery in the “fuzzy atmosphere” of Rosetta’s comet may lend some credence to this theory. Read More >>
