4 SOUTH PASADENA - SAN MARINO Mountain Views-News Saturday, March 11, 2017 New NASA Radar Technique Finds Lost Lunar Spacecraft Huntington Exhibit Octavia E. Butler: Telling My Stories NASA Marks Women’s History with Virtual Tour Finding derelict spacecraft and space debris in Earth’s orbit can be a technological challenge, however, a new technological application, announced Thursday, of interplanetary radar pioneered by scientists at NASA’s Jet Propulsion Laboratory, has successfully located spacecraft orbiting the Moon -- one active, and one dormant. This new technique could assist planners of future Moon missions. “We have been able to detect NASA’s Lunar Reconnaissance Orbiter [LRO] and the Indian Space Research Organization’s Chandrayaan-1 spacecraft in lunar orbit with ground-based radar,” said Marina Brozovic, a radar scientist at JPL and principal investigator for the test project. “Finding LRO was relatively easy, as we were working with the mission’s navigators and had precise orbit data where it was located. Finding India’s Chandrayaan-1 required a bit more detective work because the last contact with the spacecraft was in August of 2009.” Add to the mix that the Chandrayaan-1 spacecraft is very small, a cube about five feet (1.5 meters) on each side -- about half the size of a smart car. Although the interplanetary radar has been used to observe small asteroids several million miles from Earth, researchers were not certain that an object of this smaller size as far away as the Moon could be detected, even with the world’s most powerful radars. Chandrayaan-1 proved the perfect target for demonstrating the capability of this technique. Finding a derelict spacecraft at lunar distance that has not been tracked for years is tricky because the Moon is riddled with mascons (regions with higher-than-average gravitational pull) that can dramatically affect a spacecraft’s orbit over time, and even cause it to have crashed into the Moon. JPL’s orbital calculations indicated that Chandrayaan-1 is still circling some 124 miles (200 kilometers) above the lunar surface, but it was generally considered “lost.” However, with Chandrayaan-1, the radar team utilized the fact that this spacecraft is in polar orbit around the Moon, so it would always cross above the lunar poles on each orbit. So, on July 2, 2016, the team pointed Goldstone and Green Bank at a location about 100 miles (160 kilometers) above the Moon’s north pole and waited to see if the lost spacecraft crossed the radar beam. The team used data from the return signal to estimate its velocity and the distance to the target. This information was then used to update the orbital predictions for Chandrayaan-1. “It turns out that we needed to shift the location of Chandrayaan-1 by about 180 degrees, or half a cycle from the old orbital estimates from 2009,” said Ryan Park, the manager of JPL’s Solar System Dynamics group, who delivered the new orbit back to the radar team. “But otherwise, Chandrayaan-1’s orbit still had the shape and alignment that we expected.” Hunting down LRO and rediscovering Chandrayaan-1 have provided the start for a unique new capability. Working together, the large radar antennas at Goldstone, Arecibo and Green Bank demonstrated that they can detect and track even small spacecraft in lunar orbit. Ground-based radars could possibly play a part in future robotic and human missions to the Moon, both for a collisional hazard assessment tool and as a safety mechanism for spacecraft that encounter navigation or communication issues. A new exhibition opening this spring at The Huntington Library, Art Collections, and Botanical Gardens examines the life and work of celebrated author Octavia E. Butler (1947–2006), the first science fiction writer to receive a prestigious MacArthur “genius” award and the first African- American woman to win widespread recognition writing in that genre. “Octavia E. Butler: Telling My Stories” opens April 8, in the West Hall of the Library and continues through Aug. 7. Butler’s literary archive resides at The Huntington. “She was a pioneer—a master storyteller who brought her voice, the voice of a woman of color, to science fiction,” said Natalie Russell, assistant curator of literary manuscripts at The Huntington and curator of the exhibition. “Tired of stories featuring white, male heroes, she developed an alternative narrative from a very personal point of view.” A Pasadena, Calif., native, Butler told the New York Times in a 2000 interview: “When I began writing science fiction, when I began reading, heck, I wasn’t in any of this stuff I read. The only black people you found were occasional characters or characters who were so feeble-witted that they couldn’t manage anything, anyway. I wrote myself in, since I’m me and I’m here and I’m writing.” Butler would have been 70 in 2017; she died an untimely death at age 58, apparently of a stroke at her home in Seattle. After Butler’s death, The Huntington became the recipient of her papers, which arrived in 2008 in two four-drawer file cabinets and 35 large cartons. “She kept nearly everything,” said Russell, “from her very first short stories, written at age 12, to book contracts and programs from speaking engagements. The body of materials includes 8,000 individual items and more than 80 boxes of additional items: extensive drafts, notes, and research materials for more than a dozen novels, numerous shorts stories and essays, as well as correspondence and other materials. By the time the collection had been processed and catalogued, more than 40 scholars were asking to get access to it. In the past two years, it has been used nearly 1,300 times—or roughly 15 times per week, said Russell, making it one of the most actively researched archives at The Huntington. “Octavia E. Butler: Telling My Stories” will include examples of journal entries, photographs, and first editions of her books, including Kindred, arguably her best-known work. The book is less science fiction and more fantasy, involving an African-American woman who travels back in time to the horrors of plantation life in pre-Civil War Maryland. “I wanted to reach people emotionally in a way that history tends not to,” Butler said about the book. Published in 1979, Kindred continues to command widespread appeal and is regularly taught in high schools and at the university level, as well as chosen for community- wide reading programs and book clubs. In celebration of last week's International Women’s Day and Women’s History Month in March, NASA has unveiled an educational virtual tour that brings students into the exciting careers of seven women in science, technology, engineering and math (STEM) fields at the agency. Building on NASA’s participation with the 20th Century Fox film “Hidden Figures,” NASA’s Modern Figures tour introduces several amazing women, including two from the agency’s Jet Propulsion Laboratory in Pasadena, California, who are contributing to America’s space program today, and is the first NASA-themed career tour available via the free Google Expeditions mobile app. NASA’s Modern Figures virtual tour gives students a three- dimensional experience in a 100,000-square-foot aircraft hangar, simulated Martian landscape, Space Flight Operations Facility, and other fascinating locations where these women work as materials scientists, launch directors, software engineers, and in other STEM fields. The agency signed a Space Act Agreement with Google in late 2016 to collaborate in the areas of education and public engagement, which includes developing a series of NASA-themed virtual field trips and tours available freely to classrooms worldwide. In addition to the Modern Figures Expedition, NASA contributed content for the development of a 3-D tour of the International Space Station, as well as two new tours that allow students to experience NASA’s Juno mission to Jupiter, and the surface of Mars, as captured by NASA rovers. These tours provide virtual field trip experiences that teachers can lead while students view NASA content in 3-D via Google Cardboard viewers in their classrooms. The Google Expeditions partnership supports NASA’s mission to inspire and attract kids into STEM studies and careers by providing opportunities for students to virtually step out of the classroom and experience NASA careers, missions and locations in space without leaving their desks. JPL, a division of Caltech in Pasadena, California, manages the Juno mission and the Mars Exploration Program for the agency. Tracy Drain and Christina Diaz of JPL are among the women featured in NASA’s Modern Figures Google Expedition. For more information about NASA’s exciting exploration missions, go to: nasa.gov.

Free CERT Emergency Skills Training Free training for CERT graduates, Neighborhood Watch Block Captains, Amateur Radio Operators, and the general public. The goal of the meeting, April 12 from 7:00 p.m.-9:00 p.m., is to educate and empower groups of neighbors to be self sufficient during a disaster. This will be a very hands on discussion of the steps required to build a plan for you and your closest neighbors. The Golden Hour is the one hour you have after an earthquake to find any neighbors who may be injured and trapped. The “Map Your Neighborhood” training will help empower you and your neighbors to develop a plan where “neighbors help neighbors” until help can arrive. Please bring 1-5 neighbors so that you can work as a team on your plan. The event will be at Library Community Room - 1115 El Centro Street, South Pasadena. Board Seeks Community Input on South Pasadena Middle School Gymnasium The South Pasadena Unified School District (SPUSD) School Board will conduct a public hearing March 14 at 6:30 p.m. during the board meeting to receive comments about construction related to the South Pasadena Middle School (SPMS) old gymnasium building. Specifically, the Board wants to hear the community’s perspective on repurposing the existing space versus replacing the structure. The future building will be a vibrant addition to the campus and will house a black box theater, instructional space for art classes and a lab for robotics and other STEM programs. “The Board wants to hear the community’s thoughts about whether to replace or reconfigure this building. As we come to a decision, multiple factors will be taken into account including architectural and engineering considerations, cost, and community input. We will consider all factors as we determine a construction plan for this important instructional space,” said Elisabeth Eilers, SPUSD School Board president. The structure, originally built as a gymnasium for students on the SPMS campus, has been partially retired for the past several years. Currently, only a portion of the building is being used due to outdated systems and access issues requiring costly updates and improvements. Expected to serve all SPMS students, the future structure may be used for community events as well. Once the School Board determines direction, planning is expected to last approximately 14 months. Construction could begin as early as fall 2018, with completion expected approximately one year later. In addition to attending the public hearing at the SPUSD office, community members also may express opinions about this project electronically, through a link on the SPUSD website at spusd. net under Information & Announcements or by mailing correspondence to SPUSD Superintendent Geoff Yantz, 1020 El Centro Street, South Pasadena, California 91030.
