Rosetta gets ringside seat to smelly comet outburst

August 11, 2015

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

July 10, 2015

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.

Engineers seek to stabilize radio link with comet lander

June 15, 2015

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

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.

Rosetta keeps its distance from awakening comet

April 12, 2015

Mission controllers are rethinking a series of close-up comet flybys planned for Europe’s Rosetta spacecraft after a haze of dust around the comet’s central nucleus led to navigation errors during a close encounter in late March.

Diverse destinations considered for new interplanetary probe

April 6, 2015

Science teams from across the United States have submitted 28 proposals for missions to explore the moons of Jupiter and Saturn, touch the asteroid-like satellites orbiting Mars, visit unseen worlds and hunt for objects that could strike Earth one day.

Rosetta probe disoriented by comet dust

April 5, 2015

Ground controllers are analyzing a fault aboard Europe’s Rosetta spacecraft after an encounter with comet dust confused the probe’s navigation system, leaving the robot explorer in a temporary safe mode and halting regular science operations.
