Claudia Alexander dies at 56; JPL researcher oversaw Galileo, Rosetta missions by Elaine Woo (LA Times)

a Colleagues at the Jet Propulsion Laboratory said Claudia Alexander was particularly keen on engaging the public in space science. In her spare time, she wrote two books on science for children.
Claudia Alexander, a NASA scientist who oversaw the dramatic conclusion of the space agency's long-lived Galileo mission to Jupiter and managed the United States' role in the international comet-chasing Rosetta project, died July 11 at Methodist Hospital of Southern California in Arcadia. She was 56.

The cause was breast cancer, said her sister, Suzanne Alexander.

During nearly three decades at NASA's Jet Propulsion Laboratory in La CaƱada Flintridge, Alexander was known for her research on subjects including solar wind, Jupiter and its moons, and the evolution and inner workings of comets.

She was the last project manager of Galileo, one of the most successful missions for exploring the distant reaches of the solar system. Alexander was leading the mission when scientists orchestrated its death dive into Jupiter's dense atmosphere in 2003, when the spacecraft finally ran out of fuel after eight years orbiting the giant planet.

Most recently, she was Rosetta's U.S. project manager, coordinating with the European Space Agency on the orbiter's journey to rendezvous with the 67P/Churyumov-Gerasimenko comet as it circles the sun.

Colleagues said Alexander was particularly keen on engaging the public in space science.

She spearheaded Rosetta's efforts to involve amateur astronomers through social media and recognize the value of their ground-level observations of the spacecraft's path toward deep space. In particular, she spurred the creation of a Facebook group where members of the amateur community post comments on their sightings and interact with her and other scientists.

“Claudia's vision was to engage and empower the amateur community via various social media… a new wrinkle on the concept” of public engagement in NASA’s missions, said Padma A. Yanamandra-Fisher, a senior research scientist with the Space Science Institute who coordinated the outreach.

She "had a special understanding of how scientific discovery affects us all, and how our greatest achievements are the result of teamwork, which came easily to her," JPL director Charles Elachi said in a statement. "Her insight into the scientific process will be sorely missed."

Alexander was born in Vancouver, Canada, on May 30, 1959. She moved to the Silicon Valley with her family when she was 1 and grew up in Santa Clara. Her father, Harold Alexander, was a social worker and her mother, Gaynelle, was a corporate librarian for chip-maker Intel.
As an African American in a predominantly white community, Alexander felt isolated. Writing became a refuge for her.
According to the obituary: 'She wanted to study journalism at UC Berkeley, but her parents "would only agree to pay for it if I majored in something 'useful,' like engineering," she said in an interview for the Rosetta website.' Fortunately, her parents steered her...
"I was a pretty lonely girl," she recalled in a feature for the University of Michigan's Engineering Magazine. "I was the only black girl in pretty much an all-white school and spent a lot of time by myself — with my imagination."

She wanted to study journalism at UC Berkeley, but her parents "would only agree to pay for it if I majored in something 'useful,' like engineering," she said in an interview for the Rosetta website.

During college she became an engineering intern at NASA's Ames Research Center near San Jose. But she found herself drawn to the space facility and visited it as often as she could. Her supervisor eventually arranged for her to intern in the space science division.

She went on to earn a bachelor's degree in geophysics at UC Berkeley and a master's in geophysics and space physics at UCLA. At the University of Michigan, she wrote her doctoral thesis on comet thermophysical nuclear modeling and earned a PhD in atmospheric, oceanic and space sciences.

In 1986, she joined JPL as a team member for Galileo, which was still years from launching.

In 2000, she became Rosetta's U.S. project scientist at the relatively young age of 40.

"She was always looking to improve the project and make things flow better," said Paul Weissman, an interdisciplinary scientist on Rosetta. "Europeans can be difficult about collaborations. Claudia would get people to open up and work together."

In 2003, she became Galileo project manager, guiding efforts to destroy the venerable spacecraft to prevent it from accidentally crashing into and contaminating any of Jupiter's moons.

She had also served as a science coordinator on the Cassini mission to Saturn.

In her spare time, Alexander wrote two books on science for children and mentored young people, especially African American girls. "She wanted children of color to see themselves as scientists," her sister Suzanne said.

A fan of the steampunk movement in science fiction, Alexander wrote and published short stories in the genre. She wore the Victorian-style clothing associated with steampunk fashion when she taped a TED talk on how to engage youths in math and science. Her lecture will be released later this year.

Alexander was never married and had no children. Besides her mother and sister, she is survived by a brother, David Alexander.

GUEST POST: David Haas -- Fight Cancer With Physical Fitness


When a cancer patient first finds out he or she has any form of cancer, skin cancer, liver cancer, colon cancer, breast cancer, mesothelioma, or any other type of cancer, one of their first questions is what they can do to help their body fight the disease. Conventional ideology by patients and cancer treatments staff, including doctors, was to rest and take it easy during diagnosis, treatment and remission stages. Yet recent studies have indicated that physical activity no matter what your stage of cancer can have tremendous health benefits.

According to the National Cancer Institute, physical activity is a critical component of something called energy balance, and not only does it increase energy levels, it can also reduce the risk of some cancers, like breast cancer and colon cancer.

Physical activity has the added benefit of improving overall quality of life and reducing fatigue. It is also associated with positive psychological effects that result from the knowledge of taking good care of one's body, the release of feel good chemicals like serotonin, and the hope of not giving-up.

Studies into the benefits of physical activity in those who have cancer have indicated a positive correlation between increased recurrence rates and chances of survival in those who were more active post-diagnosis.

Exercise also strengthens the body and increases its natural defense mechanisms. This helps the body withstand rigorous treatments like chemotherapy by reducing the side effects like nausea and fatigue, fights off any opportunistic infections and empowers the body to mend. It also helps reduce excessive body fats that are a risk factor for chronic diseases like heart disease. Other conditions that are positively affected by physical activity are cholesterol, diabetes and high blood pressure.

Finally, exercise also promotes good sleeping and this is especially beneficial to cancer patients as they bodies need rest. Therefore, contrary to conventional thoughts on resting which involved keeping sedimentary, good rest along with a host of other health benefits can result from keeping physically active. Therefore whether a patient was just diagnosed, is going through treatment or is in remission, physical activity is an important component of their weekly regimen. Exercise does not need to be intensive, even the smallest changes that keep one active like walking a dog or taking the stairs can make a difference. It is important to check with a doctor first before getting started.
