Living with a comet: RPC team perspective

RPC, the Rosetta Plasma Consortium, comprises five sensors tasked with investigating the magnetic, electric and plasma environment of Comet 67P/Churyumov-Gerasimneko – the most well-known results perhaps being that of the “Singing Comet” and the non-magnetised nature of...

Science ‘til the very end

Rosetta will collect science data until the very end of its descent on Friday. The opportunity to study a comet at such close proximity makes the descent phase one of the most exciting of the entire mission....

Ambition – Epilogue: The Journey Continues

After her long, arduous training, our young Apprentice is now a fully fledged Master of cosmic origins, exploring an alien planet rich with water and life. But something familiar crosses her mind. Memories from her training, and...

Living with a comet: a VIRTIS team perspective

Rosetta’s VIRTIS instrument (Visible and Infrared Thermal Imaging Spectrometer) has collected over 200 million spectra concerning the nature of Comet 67P/C-G’s nucleus and the gases in the coma. Principal Investigator Fabrizio Capaccioni gives the behind the scenes...

Living with a comet: A ROSINA team perspective

Rosetta’s ROSINA (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) suite of instruments have made plenty of big headlines over the last two years, with the surprising discovery of molecular oxygen and nitrogen and the ‘flavour’ of...

The surprising comet

As Rosetta began homing in on Comet 67P/Churyumov–Gerasimenko in the weeks leading up to its arrival in August 2014, it became very clear that this was no ordinary comet. But its striking shape was only just the...

Living with a comet: a COSIMA team perspective

Comet dust particles may be small, but they come in large numbers. COSIMA Principal Investigator Martin Hilchenbach shares some impressive facts about the instrument’s performance, and reflects on the personal highlights of the team during Rosetta’s mission....

Living with a comet: a GIADA team perspective

Rosetta’s Grain Impact Analyser and Dust Accumulator GIADA has detected and measured the properties of some 6650 comet dust particles. Principal Investigator Alessandra Rotundi reports on the “beautiful results” that her team’s instrument has collected at Comet...

Living with a comet: a MIDAS team perspective

This is the first of a series of blog posts that delve behind the scenes of Rosetta’s instrument teams to find out what it was really like “living with a comet” for two years, with some impressive...

Summer fireworks on Rosetta’s comet

Brief but powerful outbursts seen from Comet 67P/Churyumov–Gerasimenko during its most active period last year have been traced back to their origins on the surface. In the three months centred around the comet’s closest approach to the...

Rosetta’s descent towards region of active pits

Squeezing out unique scientific observations until the very end, Rosetta’s thrilling mission will culminate with a descent on 30 September towards a region of active pits on the comet’s ‘head’. The region, known as Ma’at, lies on...

The great pit of Deir el-Medina

On 30 September, Rosetta will descend towards a smooth region in Ma’at, on the smaller of the two lobes of Comet 67P/Churyumov-Gerasimenko. It will target a region that is home to several active pits measuring over 100...
