Summer 2020: a virtual NASA internship

The summer of 2020 was a far-out one for many people, but for Ferrill Rushton, a 2020 electrical engineering alumnus of the Jacobs School, it was really, really far-out; to deep space, to be exact. Rushton, who is returning to UC San Diego this fall to work towards his master’s degree in photonics, was an intern at NASA’s Space Communication and Navigation (SCaN) Internship Project, analyzing photon counting methods that affect deep space communications.
The internship was designed to be an in-person research experience, but Rushton and the NASA team quickly transitioned to create a meaningful remote internship when the COVID-19 pandemic forced many plans to change.

When electromagnetic radiation from certain deep space communications or low-power systems in low-Earth orbit gets to a receiver on Earth, there is so little incoming light that the photons actually need to be counted. Rushton’s job this summer was to quantify the inefficiency in photon counting methods in situations where a ground station is detecting incoming light from these photon-depraved situations. The results from his project—Finding the Modes of Arbitrary 2D Geometries Using Finite Difference Techniques—will be incorporated into existing NASA frameworks.
“I don’t feel like I was given work just so there could be an internship, they had all this real work for us,” Rushton said.
The internship allows students to perform hands-on training with real mission scenarios, gain exposure and analyze powerful space communication systems, utilize networks software tools and effectively communicate their findings in a final presentation to NASA management. Each student is paired with an experienced and multidisciplinary mentor who counsels the student with his/her work, and also engages with career planning.

At UC San Diego, Rushton was involved with SPIE—the International Society of Optics and Photonics—serving as treasurer of the UC San Diego branch last year. He is also involved in Engineers for Exploration, on the Maya Archaeology team.
His advice to current and future students?
“If there's something that you want, there's no reason not to apply for it. Never be afraid to put yourself out there.”

Combining soft robotics and space technology

Paul Glick, a Ph.D. student at the Jacobs School, got a unique chance to do hands-on at the Jet Propulsion Laboratory in Pasadena, Calif.
Glick, who works in the lab of mechanical engineering professor and roboticist Michael Tolley, got to design and carry out most of the experiments for an electrostatic gripper for flexible objects build by JPL and UC Berkeley engineers. The team presented their work at the IROS 2017 conference in late September in Vancouver.
Glick is part of the NASA Space Technology Research Fellowship program. He works to bring soft robotics to space technology. Here is a more detailed description of his research. 
Tolley's group will present some of their research at the Oct. 27 Contextual Robotics Forum here on the UC San Diego campus. 
Watch a video of the gripper that Glick ran experiments on in action:

Here is more about the project Caleb worked on this summer, via JPL's newsletter:

Glide, don't land, to study an asteroid
There's intense interest in studying asteroids, but the challenge is getting near them. There isn't enough gravity or atmosphere to allow a spacecraft to touch down without ricocheting off the surface.
But why land when you can glide? JPLer Marco Quadrelli's Electrostatic Glider (E-Glider) was inspired by the idea of dust fountains visible on our moon's surface: when warmed by the sun, these dust particles gain an electrostatic charge. The same principle turns every asteroid or comet's dust into a weak but usable power supply.
Quadrelli's glider would be a low-cost craft attached to foil-like streamers. These streamers would inflate and lift based on the electrostatic energy around them. The glider could then be steered around an asteroid and perform basic science readings on its composition

MAE Alumnus, Douglas C. Hofmann, Earns Presidential Early Career Award for Scientists and Engineers

Douglas C. Hofmann, an alumnus from the Department of Mechanical and Aerospace Engineering at the UC San Diego Jacobs School of Engineering is developing bulk metallic glasses to be used as shielding for spacecraft to protect them against orbital debris impacts. For this and related work, Hofmann  has been named a recipient of a Presidential Early Career Award for Scientists and Engineers (PECASE). This is the highest honor bestowed by the United States Government on science and engineering professionals in the early stages of their independent research careers.

Douglas C. Hofmann
Hofmann earned a B.S. (’02) and M.S. (’03) in mechanical engineering from UC San Diego. He was advised by Kenneth Vecchio, now Professor and Chair in the NanoEngineering Department at UC San Diego. Hofmann went on to earn a M.S. and Ph.D. in Materials Science at Caltech before founding the Metallurgy Laboratory at NASA JPL in 2012, where he works as a Principle Investigator. Hofmann also teaches at Caltech, where he has a Visiting Associate appointment.

Hofmann is being honored “for his innovative research in metal-matrix composites for future NASA missions.”

In December 2012, Hofmann gave a seminar at UC San Diego on related work entitled “Amorphous Metals (AMs) & Composites for NASA Spacecraft Hardware; Science & Applications.” The abstract for that talk is below:

The current talk focuses on the science and applications of new materials for future NASA spacecraft, with emphasis on how real-world problems drive materials development. Among the materials that will be discussed are amorphous metals and bulk metallic glass composites. These materials have been developed for use as low-temperature gears for a future Mars rover, orbital debris shielding for spacecraft and satellites, net-shaped mirrors, cellular structures and optical mounts. In each application, a new material or manufacturing process enables a function that cannot be obtained through traditional techniques. Collaboration between Dr. Hofmann’s and Professor Vecchio’s groups on some of these materials will be discussed. The talk will also contain details on an upcoming NASA spaceflight experiment to the International Space Station in 2016 to perform fundamental physical science research using the new Materials Science Research Rack.

"We have been developing bulk metallic glasses to be used as shielding for spacecraft to protect them against orbital debris impacts. This is the same problem highlighted in the recent movie 'Gravity', Hoffman wrote in a recent email. 

The Presidential Early Career Awards, according to a statement released on the White House website, embody the high priority the Obama Administration places on producing outstanding scientists and engineers to advance the Nation’s goals, tackle grand challenges, and contribute to the American economy.

“The impressive achievements of these early-stage scientists and engineers are promising indicators of even greater successes ahead,” President Obama said. “We are grateful for their commitment to generating the scientific and technical advancements that will ensure America’s global leadership for many years to come.”
