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.

Measuring Low Concentrations of Liquid Water in Soil

Electrical-impedance measurements serve as sensitive indications of moisture content. An apparatus has been developed for measuring the low concentrations of liquid water and ice in relatively dry soil samples. Designed as a prototype of instruments for measuring the liquid-water and ice contents of Lunar and Martian soils, the apparatus could also be applied similarly to terrestrial desert soils and sands. The high sensitivity of this apparatus is best appreciated via a comparison: Whereas soil moisture contents of agricultural interest range between 3 and 30 weight percent, this apparatus is capable of measuring moisture contents from 0.01 to 10 weight percent (at room temperature). Moreover, it has been estimated that optimization of the design of the apparatus could enable measurement of moisture contents as low as 1 part per million by weight.
