Modular Space Telescope Could Be Assembled By Robot

09-28-16

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]

Tyler Okamoto Receives 2016 Henry Ford II Scholar Award

06-01-16

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.

Space Solar Power Initiative

04-28-15

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.

Using Space Wisely

01-09-14

The Winter 2013 issue of Engineering & Science features Professor Sergio Pellegrino's Space Structures Laboratory in the Guggenheim building. “The goal for much of my work,” says Pellegrino, “is to make simpler and cheaper spacecraft. I want to use clever structural engineering to make access to space more affordable.” The article also describes him and his team's work on the AAReST project (Autonomous Assembly of a Reconfigurable Space Telescope) as well as applications of his work to solar concentrators.

Students Work on Proposed Space Mission for Final Project

07-18-12

For the past few years, students in Professor Sergio Pellegrino's Aerospace Engineering course (Ae105), have helped design, prototype, and test various pieces of AAReST, a space-telescope demonstration mission currently under development. "It's really different from all of our other classes," says Aerospace graduate student Manan Arya. "You're actually doing work that's going to go into space. It's really exciting." [Caltech Feature]
