Rosetta’s deep-space ringtone

One of the responsibilities of the engineers on any mission's Flight Control Team is to monitor the spacecraft and react immediately in case of trouble.

How Rosetta gets passivated

Since Rosetta wasn't designed to have its transmitter permanently off, we had to change the on-board software by patching it.

How we heard from Philae

I picked up the phone and said: 'This has to be bad news. We've got a safe mode, don't we?' He replied, 'Well, maybe not. Maybe it's good news!'

Year-end break

A short note from the blog team here at ESA: we expect to take a year-end break between Monday, 22 December 2014 and Monday, 5 January 2015.

What’s up with Rosetta

Contrary to the pre-landing phase, where the trajectories flown were designed with the lander delivery always in mind, we have now entered the science phase of the mission.

Reddit AMA 20 Nov 19:00CET start

Engineers from Rosetta mission control at ESOC, Germany, the Rosetta Science Operations Centre at ESAC, Spain, and the Lander Control Centre, Cologne, will take part in a reddit AMA (Ask me Anything!) on Thursday, 20 November 19:00CET...
