During the last month of Rosetta's operations at Comet 67P/Churyumov-Gerasimenko, it was no longer possible to observe the comet with telescopes on Earth because it was too close to the Sun's position in the sky and therefore not visible in the night-time.

ESA’s historic Rosetta mission has concluded as planned, with the controlled impact onto the comet it had been investigating for more than two years.

Over the past two years, Rosetta has kept a close eye on many properties of Comet 67P/Churyumov-Gerasimenko, tracking how these changed along the comet's orbit. A very crucial aspect concerns how much water vapour a comet releases into space, and how the water production rate varies at different distances from the Sun.

Rosetta is set to complete its historic mission in a controlled descent to the surface of its comet on 30 September, with the end of mission confirmation predicted to be within 20 minutes of 11:20 UTC (13:20 CEST).

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 beginning of the comet's surprises.

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.

Rosetta is set to complete its mission in a controlled descent to the surface of its comet on 30 September. Members of the media are invited to join Rosetta science and mission control experts at ESA's European Space Operations Centre (ESOC) in Darmstadt, Germany, on 29 and 30 September, to follow the conclusion of this historic mission.

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'.

Rosetta's dust-analysing COSIMA (COmetary Secondary Ion Mass Analyser) instrument has made the first unambiguous detection of solid organic matter in the dust particles ejected by Comet 67P/Churyumov-Gerasimenko, in the form of complex carbon-bearing molecules.

Less than a month before the end of the mission, Rosetta's high-resolution camera has revealed the Philae lander wedged into a dark crack on Comet 67P/Churyumov-Gerasimenko.

Rosetta has imaged the smallest grains of Comet 67P/Churyumov-Gerasimenko's dust yet, with its Micro-Imaging Dust Analysis System, MIDAS.

In unprecedented observations made earlier this year, Rosetta unexpectedly captured a dramatic comet outburst that may have been triggered by a landslide.

Detailed analysis of data collected by Rosetta show that comets are the ancient leftovers of early Solar System formation, and not younger fragments resulting from subsequent collisions between other, larger bodies.

Rosetta is set to complete its mission in a controlled descent to the surface of its comet on 30 September.

Ingredients regarded as crucial for the origin of life on Earth have been discovered at the comet that ESA's Rosetta spacecraft has been probing for almost two years.

Rosetta's comet has been seen changing colour and brightness in front of the ESA orbiter's eyes, as the Sun's heat strips away the older surface to reveal fresher material.

ESA's Rosetta spacecraft has revealed a surprisingly large region around its host comet devoid of any magnetic field.

Silent since its last call to mothership Rosetta seven months ago, the Philae lander is facing conditions on Comet 67P/Churyumov-Gerasimenko from which it is unlikely to recover.

There are no large caverns inside Comet 67P/Churyumov-Gerasimenko. ESA's Rosetta mission has made measurements that clearly demonstrate this, solving a long-standing mystery.

Observations made shortly after Rosetta's arrival at its target comet in 2014 have provided definitive confirmation of the presence of water ice.
