GLAST Gets Shades, Blankets for the BeachThe Gamma-ray Large Area Space Telescope (GLAST) is currently receiving finishing touches at the Cape Canaveral Air Force Station, near the beaches of eastern central Florida. The spacecraft is set for launch aboard a Delta II rocket no earlier than June 3. The launch window runs from 8:45 a.m. to 10:40 p.m. PDT. SLAC managed the development of the GLAST's main instrument, the Large Area Telescope, and runs the Instrument Science Operations Center (ISOC), which will process data for the duration of the mission. Sun shades were recently installed on GLAST at the Astrotech Facility, located near the Kennedy Space Center. "These are light shades on the star tracker optics [optics that measure where the observatory is pointing] that keep light outside of the field of view from obscuring the star field," said Al Vernacchio, GLAST Deputy Project Manager at NASA's Goddard Space Flight Center. "Sun shades are like a visor you flip down in your car on a sunny day to block the Sun's glare so you can see the road," said Steve Ritz, GLAST Project Scientist at Goddard. They "shade" the star tracker field-of-view from stray light coming from the Sun, the Earth and the Moon, so GLAST's star trackers can see the needed reference stars. GLAST uses reference stars to check its orientation. Basically, GLAST is navigated using both GPS and the stars. Read more... |

Tom Rizzi: Team Lead for DOE/SSO by Day, Chiropractor by NightWhile most people enjoy heading home after work to sit down and relax, Tom Rizzi likes heading back to the office—at his second job as a chiropractor. A couple of nights a week the Department of Energy (DOE) Team Lead for Environment, Safety and Health (ES&H) and Facility Operations goes to his chiropractic practice in Mountain View. Many wonder where he finds the time and energy to do it all. "I'm one of those people who never sleeps," he says jokingly (we think). "People ask me if I'm tired when I get there and I always answer no. I really enjoy going to the office. It’s a total shift in gears," he says. Rizzi says he genuinely has fun at his practice partly because, "I'm the boss." Being a chiropractor is more than just fun—it's rewarding. "I get people out of pain," says Rizzi. "People come to me hurting and they leave feeling better." Rizzi can relate to such a difference in his clients' lives: when he was 14 years old a football accident resulted in a small fracture of one of his vertebrate, which left him with a great deal of back pain. His father eventually took him to a chiropractor, and the therapy relieved the pain allowing Rizzi to get back into an active lifestyle. From that point on, he knew he wanted to be a chiropractor. After receiving his BS in biology, Rizzi worked at several local biotechnology companies doing medical research. Rizzi later went back to school to earn a doctor of chiropractic degree, obtained his chiropractors license, and bought a large private practice. When the business aspects of his practice made it more than he could handle alone, Rizzi found that his training in back injuries and ergonomics prepared him to be an on-the-job safety advisor. After working in the private sector as a safety engineer for several companies including SLAC, he was recruited by the DOE almost a year and a half ago. Rizzi says he loves working in the DOE office, where people occasionally ask him for back advice—which he's happy to give. Today, Rizzi's active lifestyle shows little sign of the back injury from years ago. He's an avid athlete, taking time to snow ski, water ski, hike and bike. He and his wife, both San Jose natives, recently returned from a hiking trip to Yosemite National Park. |
