Rosetta update: Both "big burns" completed successfully

Emily Lakdawalla • June 10, 2014 • 7

Rosetta is now in the final phase of its approach to comet 67P/Churyumov-Gerasimenko after a decade-long journey. The two largest burns have now succeeded, and Rosetta reported this morning via Twitter that the second burn was close to perfect.

Pretty pictures: Rosetta's comet is now acting like one!

New photos from ESA's comet-chaser show its destination comet, 67P/Churyumov-Gerasimenko, developing a coma.

Rosetta update: Final orbit matching phase has begun

Emily Lakdawalla • May 08, 2014 • 1

Rosetta is in the final stage of its approach to comet 67P Churyumov-Gerasimenko. Yesterday, the spacecraft successfully performed the first of ten burns it needs to match velocity with the comet.

Rosetta update: Instrument commissioning going well; Philae cameras activated

Emily Lakdawalla • April 22, 2014

Rosetta and Philae have very nearly completed a six-week phase of spacecraft and instrument checkouts to prepare the mission to do science. Recently, the lander used its cameras for the first time since hibernation, producing some new photos of Rosetta in space.

Rosetta has turned on its cameras and sighted its comet for the first time since waking from hibernation. Next activity: waking the Philae lander.

The Very Large Telescope sights Rosetta's comet target, sees activity beginning

Emily Lakdawalla • March 10, 2014

Rosetta's comet target, 67P/Churyumov-Gerasimenko, has emerged from behind the Sun as seen from Earth, and the Very Large Telescope has photographed it. The new images show that cometary activity has already begun as Rosetta approaches for its August rendezvous.

Rosetta update from mission control

We spoke with (a slightly tired but hugely happy) Rosetta Spacecraft Operations Manager Andrea Accomazzo earlier this afternoon and he reports the spacecraft is doing fine!

Rosetta is awake!

Emily Lakdawalla • January 20, 2014 • 5

It was a tense half an hour for Rosetta fans all over the world as we waited for a spike in a graph to inform us that Rosetta had awoken from a 31-month slumber to phone home.

What's up in planetary missions in 2014

Emily Lakdawalla • December 31, 2013 • 4

With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.

Cometary Science at EPSC
