    NASA Television and the agency's website will air the conclusion of ESA's (European Space Agency's) Rosetta mission from 3:15 to 5 a.m PDT (6:15 to 8 a.m. EDT) Friday, Sept. 30, with NASA commentary, interviews and analysis of the successful mission. The Rosetta mission will end with the controlled decent of the spacecraft onto the surface of comet 67P/Churyumov-Gerasimenko at around 4:20 a.m. PDT (7:20 a.m. EDT).

    Rosetta’s MIRO – the Microwave Instrument for the Rosetta Orbiter – has made nearly two billion science measurements at Comet 67P/C-G, and generated over 1.5 million spectra of gases in the comet’s coma. Principal Investigator Mark Hofstadter shares his team’s highlights of the mission, the challenges faced, and a hint of what’s still to come…

    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. For the first time, Rosetta enabled scientists to monitor this quantity and its evolution in situ over two years.

    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 comet’s water being different to Earth’s among them. ROSINA principal investigator Kathrin Altwegg and colleagues reflect on the highs and lows of the 40-strong team of scientists and technicians since Rosetta woke up from deep space hibernation on 20 January 2014.

    Imagine how Rosetta's descent might look if you were an observer at Comet 67P/C-G!

    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. After more than two years spent living with the comet, Rosetta scientists reflect on some of the mission’s unexpected discoveries, the mysteries solved and the new questions raised.

    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.
