Comet 67P/Churyumov-Gerasimenko

ESA plans for Rosetta’s grand finale on comet 67P

November 14, 2015 Stephen Clark

European Space Agency flight controllers are plotting to send the Rosetta spacecraft on a controlled descent to the surface of comet 67P/Churyumov-Gerasimenko next year to join the Philae landing probe, which made a bouncy touchdown on the comet’s craggy nucleus one year ago this week.

The surface of Rosetta’s comet is changing

Views from Europe’s Rosetta comet orbiter show mysterious markings appearing on the nucleus of Comet 67P in recent months, with new surface features forming within a matter of weeks, and scientists are digging into the complex causes of the cometary erosion.

Rosetta gets ringside seat to smelly comet outburst

Europe’s Rosetta spacecraft has recorded a brilliant beam of gas and dust shooting into space from Comet 67P/Churyumov-Gerasimenko, the most spectacular such emission since the probe arrived at the tiny frozen world one year ago.

New contact with intractable comet lander

Europe’s Rosetta comet probe re-established momentary contact with the Philae lander late Thursday, renewing hopes of starting up the craft’s research instruments after two weeks of radio silence dampened the moods of scientists.

For comet scientists, elation and redemption at Philae’s wakeup

June 18, 2015 Stephen Clark

Research teams across Europe spent the last half-year meticulously going through a wish list of experiments for the Philae comet lander without knowing whether they would ever get a chance to execute the tasks.

Engineers seek to stabilize radio link with comet lander

June 15, 2015 Stephen Clark

Emboldened by renewed contact with Europe’s comet lander, engineers are repositioning the mission’s Rosetta mothership this week to establish a reliable a communications link with the dishwasher-sized Philae landing craft, a prerequisite for resuming a science campaign abbreviated by a power shortfall last year.

Comet lander wakes up!

June 14, 2015 William Harwood

The European Philae comet lander, out of power and presumably lost after bouncing into heavily shadowed terrain last November, phoned home Saturday after finally getting enough sunlight on its solar panels to transmit data to the Rosetta orbiter for relay to Earth.
