It is with great sadness that we share the news of Dr Claudia Alexander’s passing on 11 July 2015. Claudia worked for NASA at JPL. She was an eminent planetary scientist and was deeply involved with the Rosetta Mission as US Rosetta project scientist. She was passionate about outreach, including engaging amateur astronomers through the ground-based observing campaign of Rosetta’s target comet, 67P/Churyumov–Gerasimenko. Claudia was also very well known for her role in NASA’s Galileo and Cassini projects. Here, some of her ESA colleagues pay tribute: “We have lost a great colleague and friend who will live on within us and the missions to the stars she made possible.” Matt Taylor, ESA’s Rosetta project scientist “Although I did not know Claudia very well, I quickly noticed her strong (...)

US #rosetta Project Scientist Claudia Alexander and ESA’s Rosetta Project Scientist Matt Taylor report on the discussions held at the recent Rosetta #science Working Team meeting. The Rosetta Science Working Team (SWT) met for the 40th time earlier this month, this time at ESTEC in Noordwijk, Netherlands. This meeting was attended by principal investigators and co-investigators of the #Instruments and other researchers but also science #Operations personnel and staff from the mission operations team. This week the main topics discussed were the science of the mission so far, science operations and new trajectories going forward, and updates on the state of the health of the experiments and the spacecraft. Compared to our predictions and expectations, the activity of the comet is slightly (...)

Yesterday, 17 December, there was a special session dedicated to #Rosetta at the 2014 autumn meeting of the American Geophysical Union (AGU) in San Francisco. Many scientists from the #rosetta and #Philae instrument teams reported on their latest results. To kick the Rosetta day off, some of the results were also presented in a press conference featuring Matt Taylor, ESA Rosetta Project Scientist, Claudia Alexander, US Rosetta Project Scientist at NASA, Kathrin Altwegg, ROSINA Principal Investigator at the University of Bern, Switzerland and Jean-Pierre Bibring, Lead Lander Scientist at the Institut d’Astrophysique Spatiale, Orsay, France. Matt Taylor introduced the past, exciting year of Rosetta leading to the comet landing on 12 November, and Claudia Alexander summarised what we know (...)
