Dr. Alexander is the Project Scientist for the U.S. portion of the international Rosetta mission. She has also been the Cassini Project Staff Scientist and as the final project manager of the Galileo mission, overseeing its fiery crash into Jupiter. Her scientific interests include gaskinetic theory, theory of gaseous escape from planetary and cometary regoliths, theory of surface bound exospheres, magnetospheric plasma theory (terrestrial and planetary), exobiology, interdiciplinary science, and oxidation / reduction potential of planetary and cometary regoliths.

Her most recent publications include:

  • C. Alexander, A. Chmielewski, S. Gulkis, P. Weissman, D. Holmes, J. Burch, R. Goldstein, P. Mokashi, S.A. Stern, J. Parker, S. Fuselier, M. Kueppers, A. Accommazzo, “The U.S. Rosetta Project at its second Science Target: Asteroid (21) Lutetia,” IEEE Conference Proceedings, in press.
  • C. Alexander, D. Sweetnam, S. Gulkis, P. Weissman, D. Holmes, J. Burch, R. Goldstein, P. Mokashi, J. Parker, S. Fuselier, L. McFadden, “The U.S. Rosetta Project at its first Science Target: Asteroid (2867) Steins,” IEEE Conference Proceedings, 2010.
  • C. Alexander, R. Carlson, G. Consolmagno, D. Morrison, 400 Years of Discovery at Europa, Europa, Pappalardo, McKinnon, Khurana eds., University of Arizona Press, 2009.

2014, Rosetta will enter orbit around comet 67P/Churyumov-Gerasimenkoand land a probe on it, two firsts.

Rosetta’s goal is to learn the primordial story a comet tells as it gloriously falls to pieces.

Comets are primitive leftovers from our solar system's 'construction' about 4.5 billion years ago. Because they spend much of their time in the deep freeze of the outer solar system, comets are well preserved—a gold mine for astronomers who want to know what conditions were like back “in the beginning.”
