Moriah Bischann Wins SURF Speaking Competition
Material science undergraduate student Moriah Bischann, mentored by aerospace postdoctoral scholar, Dr. Owen Kingstedt, is the winner of the Doris S. Perpall Summer Undergraduate Research Fellowships (SURF) Speaking Competition. She was recognized as the best speakers-out of the 200 students who presented their SURF research. Her summer research focused on exploring the next generation of structural materials. During her ten week SURF project she studied the effects of alloying and processing on the dynamic behavior of magnesium (Mg). This work was done to address the larger question of whether Mg is a useful material for the automotive, aerospace, energy, and defense industries where a material is needed that has low density, but also the strength to withstand high impact forces.
Space Solar Power Initiative
Caltech and Northrop Grumman Corporation have signed a $17.5 million sponsored research agreement for the development of the Space Solar Power Initiative (SSPI). The initiative will develop technologies in three areas: high-efficiency ultralight photovoltaics; ultralight deployable space structures; and phased array and power transmission. "The Space Solar Power Initiative brings together electrical engineers, applied physicists, and aerospace engineers in the type of profound interdisciplinary collaboration that is seamlessly enhanced at a small place like Caltech... We are working on extremely difficult problems that could eventually provide the world with new, and very cost-competitive technology for sustainable energy,” said EAS Chair Ares Rosakis.

How To Study High-Speed Flows
Joanna Austin, Professor of Aerospace, researches fundamental problems in reactive, compressible flows with applications in hypervelocity flight and planetary entry, supersonic combustion and detonation, bubble dynamics, and explosive geological events. She remarks, “gas dynamics, and particularly looking at gas dynamics in reacting flows… [is] the thing I really love. It's a very challenging, coupled, problem. As the fluid is going through the model that you're studying, you also have to account for the fact that the state of the fluid is changing—the gas is chemically reacting, so it's changing from reactants to products, or it's redistributing its energy states, or both. Understanding how best to model these processes, that's what excites me.” [Interview with Professor Austin]
Caltech and JPL Collaborate with Indian Space Program
The Director of the Jet Propulsion Laboratory (JPL), Charles Elachi, and the Chair of Caltech’s EAS Division, Ares Rosakis, recently hosted the Chairman of the Indian Space Research Organization (ISRO), Dr. Koppillil Radhakrishnan. The visit focused on plans regarding a joined Earth-orbiting mission that will be the first radar mission to systematically and globally study the solid Earth, the ice masses, and ecosystems, all of which are sparsely sampled at present. While at Caltech Dr. Koppillil Radhakrishnan visited research facilities and delivered the Klein Lecture in Aerospace. In his presentation he highlighted the long history of connections between engineers and scientist at Caltech and in India. Dr. Radhakrishnan prides himself to be the last student of Caltech alumnus Satish Dhawan (Eng '49, PhD '51) who participated in the creation of India's space program. “Caltech has been instrumental in the training of many international space leaders,” explains Chair Rosakis “these include Satish Dhawan who was pivotal in the creation of the Indian space program and Qian Xuesen (also known as Tsien Hsue-Shen) who was the father of Chinese rocketry.” Last year the Indian Department of Space and ISRO established a fellowship at Caltech in the name of Satish Dhawan to further encourage the training of Indian students at Caltech and specifically at GALCIT.
