In January 2023, the Caltech Space Solar Power Project (SSPP) is poised to launch into orbit a prototype, dubbed the Space Solar Power Demonstrator (SSPD), which will test several key components of an ambitious plan to harvest solar power in space and beam the energy back to Earth. [Caltech story]

Once considered science fiction, technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of Caltech researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed—including to places that currently have no access to reliable power. "This is an extraordinary and unprecedented project," says Harry Atwater, Otis Booth Leadership Chair, Division of Engineering and Applied Science; Howard Hughes Professor of Applied Physics and Materials Science; Director, Liquid Sunlight Alliance. "It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world." [Caltech story]

Sergio Pellegrino, Joyce and Kent Kresa Professor of Aerospace and Civil Engineering; Jet Propulsion Laboratory Senior Research Scientist; Co-Director, Space-Based Solar Power Project, has been named the inaugural Michael M. Byram Distinguished Visiting Professor at University of Colorado (CU) Boulder’s Ann and H.J. Smead Aerospace Engineering Sciences Department. The professorship brings internationally-renowned external researchers for one or two semesters each year to CU to teach classes, host seminars, and collaborate with the faculty, further amplifying the research impact of the department.

After nearly a decade of work, a modular reconfigurable space telescope designed by students in the Ae 105 Aerospace Engineering class is nearly ready to launch. That telescope, which came to be known as AAReST (Autonomous Assembly of a Reconfigurable Space Telescope), was designed and built in large part by the students in the class, working in collaboration with the Surrey Space Centre in England and the Indian Institute of Space Science and Technology. Professor Pellegrino says that the students working on AAReST have learned how to collaborate across continents and gained skills that will continue to serve them for years to come. In addition, he says, he's proud to have given several generations of aerospace students the opportunity to work on a real space mission. When the mission launches in 2019, dozens of past and present Caltech students—along with their collaborators nearby and abroad—will be watching and holding their breath to see whether their hard work pays off.

GALCIT Graduate student Michael Marshall, who is a member of Professor Sergio Pellegrino’s Space Structures Laboratory, has received the Rudolph W. Mozer Trophy from the Soaring Society of America (SSA) for being the highest ranking contestant under 26 years of age at any U.S. National Soaring contest. He also placed 4th in the U.S. National Soaring contest. Soaring involves flying without flapping wings or using engine power, or as described by the SSA “to fly as the hawk and eagle has been mankind's dream for centuries. Modern sailplanes make soaring flight possible, and with them humans can fly higher, faster, and farther than the greatest of birds, using only an invisible force of nature to stay aloft.”

Professor Sergio Pellegrino and colleagues including Professor Joel Burdick, are proposing a space observatory with a 100 meters diameter primary mirror. Their design calls for the use of more than 300 deployable truss modules that could be unfolded to form a scaffolding upon which a commensurate number of small mirror plates could be placed to create a large segmented mirror. In this concept, a spider-like, six-armed "hexbot" would assemble the trusswork and then crawl across the structure to build the mirror atop it. [Caltech story]

Mechanical Engineering student Tyler Okamoto, mentored by Professor Sergio Pellegrino, is a recipient of the 2016 Henry Ford II Scholar Award. He is working with Professor Pellegrino’s team to build an autonomous reconfigurable space telescope using multiple nanosatellites that align in space to create a camera and mirror assembly. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.
