Who's Who : Aerospace
Lindley Johnson, Planetary Defense Officer, NASA Headquarters, Washington, D. C.

NASA’s Planetary Defense Coordination Office (PDCO), managed at NASA Headquarters in Washington, D.C., is responsible for early detection of potentially hazardous objects, like asteroids and comets, and issuing warnings about their potential impacts. This requires...

Who's Who : Materials
Adam Sidor, NASA Research Fellow, Georgia Institute of Technology, Atlanta, GA

Thermal Protection Systems (TPS) — heatshields — form the outer surface of spacecraft and provide protection as the vehicle plunges through planetary atmospheres. Conformal ablative materials are currently being developed to improve TPS performance. Adam Sidor is...

Who's Who : Sensors/Data Acquisition
Nick Krotkov, Atmospheric Scientist, Goddard Space Flight Center, Greenbelt, MD

Using data from NASA’s Earth Observing System Aura satellite, launched in 2004, a team led by Michigan Technological University created a global map of volcanic emissions. Scientist Nick Krotkov will use the information to refine climate models and better...
