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 >>

This is the Last Thing the Rosetta Spacecraft Saw Before it Died

At 11:30 BST today, a spacecraft weighing over 2,000 kilograms with the wingspan of a Boeing 747 crashed gently into a comet’s surface, following 13 hours of free-fall. These, my friends, are the last, fleeting glimpses of Comet 67P that Rosetta managed to capture before its instruments went dead. Read More >>

Everything You Need to Know to Watch Rosetta Crash Into a Comet This Week

The Rosetta spacecraft has spent three years peering at Comet 67P/Churyumov–Gerasimenko from orbit—but this week, its watch will end. Today, Rosetta begins a controlled descent to its final resting place on the edge of an enormous pit, where it’ll remain frozen until the space rock itself is destroyed, or until the universe expands into oblivion.

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 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 >>

Rosetta’s Comet Looks Even Weirder When It’s Backlit By the Sun

In its ongoing exploration of Comet 67P/Churyumov-Gerasimenko, the Rosetta spacecraft captured this stunning silhouette of the two-lobed mass from a distance of 200 miles. Wow. Read More >>

Cool Visualisation Lets You see Philae Bounce and Tumble as it Lands on a Comet

It's been one year since the Philae Lander bounced, spun, and tumbled across the surface of Comet 67P/Churyumov-Gerasimenko. To commemorate the historic event, the European Space Agency has released an animated video chronicling the lander’s chaotic landing. Read More >>

Rosetta’s Comet is Developing Giant Sinkholes Before Our Eyes

Watch your step, Philae! 67P, the comet we landed a space probe on last fall, is apparently riddled with sinkholes. And as the massive ball of ice and dust hurls itself toward the sun, its surface is continuing to evolve. Read More >>
