los altos Alum Contributes to Mars Rover curiosity Cassidy Craford Sam Lisbonne Staff Writers “Touchdown confirmed. We’re safe on Mars.” With a simple declaration, NASA’s Jet Propulsion Laboratories (JPL) once again proved their ability to execute, landing the SUV-sized rover Curiosity on Martian soil with nothing more than a thin layer of dust as evidence of its deployment. The outstanding success on August 6, 2012, represented a continuation of proud NASA heritage. For Los Altos High School graduate David Blake, the landing was the culmination of his 22-year project. Blake pioneered the development of an integral instrument, CheMin, on the Curiosity rover. However, Blake anticipated a far different career. “I knew I wanted to be a geologist [as a child],” Blake said. “I guess I never really realized I could be an employed geologist, so in college I became a
biologist, and my undergraduate degree [from Stanford] was biology.” Blake’s passion in geology led him to a career at JPL right after college, where he worked for the NASA Ames Research Center in a post-doc fellowship after earning a Ph.D. in Biology. It was then that a great idea grabbed him and captivated his attention for 22 years, culminating in the successful landing of the Curiosity rover. One day at the Ames Research Center, Blake stumbled upon a forgotten piece of equipment in an abandoned lab – a late 1940’s x-ray camera. He pictured the tool as updated and repurposed for a different, more advanced use. In that moment, Blake formulated an idea that eventually became the $40 million instrument, CheMin. “The instrument is called CheMin,” Blake said. “[CheMin] uses a technique

called x-ray diffraction or XRD [which] tells you the structure of the crystalline materials in a sample...It tells you the minerals present in a sample in a very definitive way.” Blake applied for a grant from NASA just as the Curiosity project was funded, and JPL recognized the potential in the tool and its possible application to the rover mission. The technology was streamlined to be made more efficient. CheMin eventually became a prominent and integral part of the rover’s complex analytical tools. And on October 30, 2012, after over 20 years in development, CheMin proved itself and it and Curiosity returned the first analysis of Martian soil, providing the first quantitative data to support scientific theories. Unlike the landing of Curiosity, however, Blake’s career path was far from smooth. Blake’s academic journey began at LAHS,
but he remembers little of his experience. “I remember being really scared when I was playing junior varsity football; I was not a very good football player,” Blake said. “That was a scary thing. I remember biology was a lot of fun, [but] that was a really long time ago.” During his time at LAHS, Blake said he focused much of his education on the same STEM concepts the school has begun to focus more on in the past few years. He credits much of his success, however, to simply having a good idea. “I started working on this idea in 1991,” Blake said. “The curious thing is that when you have a good idea, it may not be a good idea when you have it. It’s a good idea when people realize its a good idea … It just took a long time for people to give their attention to what I was doing, so I just kept improving it a little bit at a time.”

On Tuesday, October 23, the school added an additional class of World Literature, World Studies and Survey of Composition and Literature in order to reduce the teacher-to-student ratio of these subjects, ensuring higher quality of learning. Freshmen and sophomores were asked to move from their original classes to these new classes. History teacher Kelly Coble teaches the new World Studies class, English teacher Abigail Christensen teaches the new World Literature class and English teacher Zoe Beltz teaches the new Survey class. The main incentive of the decision was to ensure that students would have a reduced student -to-teacher ratio, especially in the freshmen and sophomore classes. “While it feels like one or two people here and there, it really is a huge difference in the classroom,” English Department head Keren Robertson said. “We really try to keep those lower grades small because there is such a small transition in social skills. The choices we’ve made as a school and as the English Department is to preference smaller classes in the lower grades because it gives them more of a foundation.” The school is usually able to achieve low student
-to-teacher ratios every year (20:1 in Survey, 25:1 in World Literature and 25:1 in World Studies) despite a higher projected enrollment of freshmen. The projection of the number of students attending Los Altos in the fall is estimated through the number of eighth graders attending middle schools that would be expected to enroll at LAHS. It does not account for students going to private schools or those who are moving to a different district. This is why, at the beginning of the year, the school usually experiences an attrition where anywhere between 15 to 30 students do not show up. Therefore, projections made in May are not necessarily accurate and can vary in August when students do show up. “Every year we get a projected enrollment, kids who are coming in through the system of the kids coming through the elementary schools, through the middle school, through the private schools how many kids will come,” Robertson said. “Some years you’re right, other years fewer students end up showing up, or some kids go to private schools or people move, move out of district. This was a really weird and unusual year with many more kids. We couldn’t have planned for it.”
