I have a special treat for y’all: a guest post! This one’s from Daniel, myfriend who is also a senior and majors in physics but knows a lot about everything else, too. Last term, he tooka really cool class on remote sensing that took him to the heart of JPL and space missions. If you’ve done Science Olympiad, perhaps you’ve heard a bit about remote sensing. (If you don’t do SciOly, don’t fret–a lot of Techers haven’t, either!) When I was in high school, I somehow took up that event and ended up taking a test about satellites and other remote sensing topics that I really should have studied…
Without further ado, some guest-post-awesomeness from Daniel!
keep lookin’ up,
Over the past Fall term, I took the class EE/Ae 157a, which was titled the “Physics of Remote Sensing”, taught by Prof. van Zyl, the Director for Solar System Exploration at JPL (yes, the person in charge of all the solar system missions including Earth-sensing projects). During the last week of classes, we were rewarded with the opportunity to have a special tour of JPL itself as given by Prof van Zyl and his colleagues. I had previously toured JPL as part of its Caltech Student Day, but this tour was on a completely different level of access.
For starters, we were taken into the Mission Control Center itself (Fig. 1-2)! During the Caltech Student Day tour, we were only allowed into the lounge overlooking the room. This is the place that coordinates every single mission from every spacefaring nation. Several helpful animations indicated which of the many large radio antennae located all over the world was communicating with which spacecraft. A multicolored command line interface indicated the data packets received from several major missions. Notably, this center is known as the “Charles Elachi Mission Control Center” (Fig 2, center), after Professor Emeritus Charles Elachi, who retired from the directorship of JPL and the vice presidency of Caltech earlier this year. As it turned out, Professor van Zyl was a student in precisely this remote sensing class when it was taught by Professor Elachi!
We were further encouraged to explore the control centre and take pictures. We promptly took advantage of the latter (Fig 3) and even chatted with the mission controllers (known as “Aces”) on duty. If that was not thrilling enough, we were then brought into the adjoining command center to watch the director’s cut of the successful arrival of Mars Science Laboratory “Curiosity” while sitting in precisely the same seats that the iconic celebration was filmed in (Fig. 4).
We ended the control center tour by snacking on a few peanuts from the stash of “lucky peanuts” reserved for special missions (similar to that in Fig. 5). Apparently, this tradition arose in 1964 after a string of expensive failures in the missions Ranger 1 to Ranger 6. That year, the next mission iteration Ranger 7 launched and performed its mission perfectly. The project team could not find anything they had done differently, save for the single observation that an engineer had passed out peanuts before that successful launch. Since then, JPL has established a tradition of eating “lucky peanuts” (the actual supplier is confidential) before each major event.
We visited a number of other locations within JPL after that, but I forgot to take pictures. Apologies.
If you are interested in finding out how satellites capture a ridiculous amount of information from orbit (millimeters of tectonic shifts from several hundred kilometers away, anyone?), EE/Ae 157a is an excllent class to take. The JPL trip was a fantastic bonus. I think I’m ready to graduate now.
This summer I had the incredible opportunity to do a 10-week internship at Gilead Sciences in Foster City, CA. For those unfamiliar, Gilead Sciences, Inc. is a research-based biopharmaceutical company focused on the discovery, development, and commercialization of innovative medicines.
With 45 Nobel Laureates on its Faculty Roster, it’s not surprising that research is an integral part of the Caltech undergraduate experience. One of the programs that promotes such research is the Summer Undergraduate Research Fellowship (SURF). There is no minimum knowledge or experience required to participate in a Caltech SURF. In fact, students can participate in a SURF as soon as the summer after their freshman year. It is not difficult to get a SURF. All you need to do is find a mentor who is working in an area of research that interests you and willing to mentor you through a research project. The mentor can work in a Caltech lab, at the NASA Jet Propulsion Laboratory (JPL), or at another participating institution. Once you find a mentor, you work together to write a project proposal that you later send to the SURF office for review and approval. About 98% of the SURF proposals get approved. This fellowship is a great way to explore various fields of research and obtain real, hands-on experience where you get to apply the theoretical knowledge you’ve learned in class. Not only do you get to work and learn alongside your mentor, but you also get compensated for your time. The length of the SURF is ten weeks, and it starts at the beginning of the summer. However, it is not uncommon for many students at Caltech to continue their research project throughout the academic school year.
Like many students at Caltech, I suffer from a slight boba addiction, where side effects may include over caffeination, minor sugar highs, and of course, a large toll on one’s wallet. This addiction is not helped by the fact that there are at least three boba shops within walking distance of campus. So, after an entire term’s worth of boba runs, I came back from winter break with a new year’s epiphany: it was time to get a job. Rather than try to curb my addiction, I decided to find a way to subsidize it.
