Jordin Kare

From Wikipedia, the free encyclopedia

Jordin Kare (born 1956) is physicist and aerospace engineer known for his research on laser propulsion. In particular, he was responsible for Mockingbird, a conceptual design for an extremely small (75 kg dry mass) reusable launch vehicle, and was involved in the Clementine lunar mapping mission.^[1][2] Kare is also known as developer of the Sailbeam interstellar propulsion concept.

[edit] Background

He received his B.S. in Electrical Engineering and Physics from the Massachusetts Institute of Technology in 1978 and Ph.D. in Astrophysics from University of California, Berkeley in 1984.^[1][5] Kare is the brother of Susan Kare, designer of the fonts and icons of the original Apple Macintosh user interface.^[4][6]

[edit] Career

Kare worked for many years at Lawrence Livermore National Laboratory. In 1996, he left LLNL and, after working briefly for a small space-related startup company, became an independent consultant specializing in advanced space system design in 1997,^[5] and started his own company.^[4] He is a leading advocate of laser propulsion for space launch and in-space propulsion. He organized a 1986 Workshop on Laser Propulsion at LLNL and later led a development program for ground to orbit laser launch supported by SDIO. He has received a NASA Institute for Advanced Concepts grant to study a near-term form of laser launch using arrays of relatively low powered lasers.^[5][7][8] He is a team member of LaserMotive^[9], a laser power beaming entrant in the Elevator:2010 Beam Power Challenge.

[edit] Sailbeam

Kare initially presented the concept of a SailBeam Boosted Magsail in a report prepared for NASA’s Institute for Advanced Concepts called “High-Acceleration Micro-Scale Laser Sails for Interstellar Propulsion”. A key idea is that if you accelerate vast numbers of tiny sails rather than one enormous one, you can bring the same amount of mass to high speeds with a less complex optical system. Unlike particle beam propulsion where the beam disperses as it travels, a stream of low-mass microsails is not limited by such diffraction. Using dielectric rather than metal sails, you can also accelerate the sails much closer to their power source. The stream of microsails then becomes a source of propulsion to a starship as particle beams mounted on the starship vaporize the incoming sails into plasma.

[edit] Filk music and science fiction

Kare is also known as a science fiction fan and filksinger. He has been a regular attendee and program participant at science fiction conventions since 1975.^[3][2] He was an editor of The Westerfilk Collection: Songs of Fantasy and Science Fiction, an important filksong collection, and later a partner in Off Centaur Publications, the first commercial publisher specializing in filk songbooks and recordings.^[3][10][11] A character with his name appears in War of Honor, a military science fiction novel in the Honor Harrington series by David Weber.
