Dr. Alexander Kashlinsky, Senior Staff Scientist, SSAI, Goddard Space Flight Center, Greenbelt, MD

Dr. Alexander Kashlinsky is a principal investigator on several NASA and NSF grants studying topics related to cosmological bulk flows, cosmic microwave and infrared background radiation, and early stellar populations. Using the Wilkinson Microwave Anisotropy Probe, Kashlinsky recently discovered a phenomenon called “dark flow,” which are clusters of galaxies moving at a constant velocity toward a 20-degree patch of sky between the constellations of Centaurus and Vella.

Dr. Drake Deming, Senior Scientist, Solar System Exploration Division, Goddard Space Flight Center

Dr. Drake Deming, former Chief of Goddard Space Flight Center’s Planetary Systems Laboratory, currently serves as Senior Scientist with NASA’s Solar System Exploration Division where he specializes in detecting and characterizing hot Jupiter extrasolar planets. Dr. Deming was named recipient of the 2007 John C. Lindsay Memorial Award, Goddard’s highest honor for outstanding contributions in space science, for his work in developing a way to detect light from extrasolar planets and use it to measure their temperatures.

Glenn Rakow, SpaceWire Development Lead, Goddard Space Flight Center, Greenbelt, MD

Glenn Rakow is the Development Lead for SpaceWire, a high-speed communications protocol for spaceflight electronics originally developed in 1999 by the Euro - pean Space Agency (ESA). Under Rakow’s leadership, the SpaceWire standard was developed into a network of nodes and routers interconnected through bidirectional, highspeed serial links, making the system more modular, flexible, and reusable. In 2004, Rakow received Goddard’s James Kerley Award for his contributions to technology transfer.

Garrett Reisman, Astronaut, NASA Johnson Space Center, Houston, TX

In March 2008, astronaut Garrett Reisman flew aboard the Space Shuttle Endeavour to the International Space Station, where he spent 95 days living and working in space. After performing his first spacewalk to help install the Space Station’s new robotic manipulator, called Dextre, he returned to Earth in June aboard the Space Shuttle Discovery.

Interview with Dr. Anthony Colaprete, LCROSS Principal Investigator, Ames Research Center

LCROSS (Lunar Crater Observation and Sensing Satellite), which will travel to the moon aboard the launch vehicle for the Lunar Reconnaissance Orbiter (LRO), will test for the presence of water beneath the lunar surface by crashing a pair of heavy impactors into one of the permanently shadowed craters at the Moon’s South Pole. The impact will create a plume of debris that can be analyzed for the presence of water using specialized instruments. Dr. Anthony Colaprete, who is an expert on the Martian climate system, is principal investigator for the LCROSS mission.

Interview with John Dunec, Branch Manager of COMSOL, Inc.

In this podcast John Dunec, Branch Manager of COMSOL, Inc., discusses how the breakthrough of multiphysics modeling techniques is making waves in the electronics industry. Applications cover everything from modeling p-n junctions in semiconductors and joule heating in circuits to forced convective cooling of circuit boards. Based on the April 9, 2008 webcast sponsored by COMSOL, this free podcast introduces you to applying multiphysics modeling techniques to electronic analysis and guides you through several examples including electro-thermal stress analysis in a surface coil, simulating a high-frequency RF inductor, and thermal effects on cross-talk between bond wires.
