Rosetta Update: What It Found, What's Next

Rosetta’s lander is hibernating on a comet now, waiting for a brighter sun. The mission’s scientists, though, have been hard at work, scrutinising reams of data and predicting how the lander could wake up. At the American Geophysical Union (AGU) meeting today, Rosetta’s scientists dropped some intriguing hints of what’s to come.


Comet Dust Has Been Hiding Out In Antarctica This Whole Time  

Last month, the European Space Agency landed on a comet 482 million kilometres away to take samples that could help unravel our solar system’s origins. It turns out there are pieces of comets closer to home too. Scientists have just found comet dust preserved in the frozen reaches of Antarctica.


The First True Colour Image Of Comet 67P Taken By The Rosetta Spacecraft

Until now, all photos of the comet 67P/Churyumov-Gerasimenko have been in greyscale. According to a research paper that will be presented at the American Geophysical Union’s 2014 Fall Meeting, you are looking at its first true colour photo, taken with Rosetta’s OSIRIS camera.


This Is What It Sounds Like To Land On A Comet

We have sound! The stream of data from Philae, the Rosetta mission’s little lander currently hibernating on comet 67, now includes the very “thump” it made while touching down. The two-second recording is more scientifically interesting than you might think.


Rosetta Is Sending Back Intriguing Data On The Origins Of Earth's Water

While you were worrying about Philae’s landing, the spacecraft Rosetta has been patiently circling the comet, doing its own science. And it’s just dropped some intriguing results into the big debate over how Earth got its water.


This Is The Definitive Photo Of The Comet Churyumov-Gerasimenko

Briefly: All photos from space are cool, but this photo of Comet 67P/Churyumov-Gerasimenko is simply masterful, the most spectacular of all the photos of the comet so far. Worthy of a Kubrick movie frame.


Philae Bouncing Off The Comet, Caught In Amazing Rosetta Images

Everyone’s favourite underdog lander, Philae, was travelling at about 49cm per second as she zoomed towards the formidable chunk of ice and rock known as 67P. That was slow enough that her mothership Rosetta was actually able to capture the descent in images released today by the ESA.


Rosetta's Lander Is Now Asleep On The Comet, Waiting For A Brighter Sun

Goodnight, Philae, though not, we hope, goodbye. The lander is now in sleep mode, keeping “all instruments and most systems on board shut down.” Thankfully, engineers managed to gather all the collected comet data before Philae’s batteries were depleted. If we’re lucky, it may wake up when it gets closer to the Sun.


First Comet Drilling Ever Confirmed: 100% Successful Mission, Says ESA

Against all odds, Philae has confirmed that the first ever drilling of a comet has happened! ESA has received telemetry data indicating that the drill worked. They also managed to send ALL data before going into sleep mode. What is Philae going to find? Perhaps the building blocks of life?


Brilliant Animation Of The Entire Comet Landing

The always amazing XKCD had, by far, the best liveblog of the historic landing on the comet 67P/Churyumov — Gerasimenko today: Each step was documented as a brilliant cartoon, which has been compiled into the flipbook above.
