Previously, preliminary data on the ability of a group of common indoor plants to remove organic chemical from indoor air was presented. The group of plants chosen for this study was determined by joint agreement between NASA and the Associated Landscape Contractors of America. The chemicals chosen for study were benzene, trichloroethylene, and formaldehyde. The results show that plants can play a major role in removal of organic chemicals from indoor air.

Near Earth objects (NEOs) are attractive targets for spacecraft missions with the purpose of obtaining greater insight to the nature of the original bodies from which the terrestrial planets formed, without having to visit the Main Belt itself. Greater knowledge of NEOs directly sheds light on the origin and evolution of the asteroid belt, the formation of planets, and the history of the solar system. This report describes a search for NEOs that would be accessible for missions launching in...

In the opening weeks of 1998 a news article in the British journal Nature reported that NASA was about to enter biology in a big way. A ''virtual'' Astrobiology Institute was gearing up for business, and NASA administrator Dan Goldin told his external advisory council that he would like to see spending on the new institute eventually reach 100 million per year. ''You just wait for the screaming from the physical scientists (when that happens),'' Goldin was quoted as saying. Nevertheless, by the...

The Mechanical Components Branch at NASA Glenn Research Center hosted a workshop on Tuesday, May 14, 2002, to discuss space mechanisms technology. The theme for this workshop was 'Working in the Cold,' a focus on space mechanisms that must operate at low temperatures. We define 'cold' as below -60C (210 K), such as would be found near the equator of Mars. However, we are also concerned with much colder temperatures such as in permanently dark craters of the Moon (about 40 K).
