Pioneer 10 Trajectory
| Title |
Pioneer 10 Trajectory |
| Full Description |
This image, drawn in 1970, is an artist's rendering of the Pioneer 10 spacecraft trajectory, with the planets labeled and a list of the instruments that were intended to be flown. Before the use of computer animation, artists were hired by JPL and NASA to depict a spacecraft in flight, for use as a visual aid to promote the project during development. Pioneer 10 was managed by NASA Ames Research Center in Moffett Field, California. The Pioneer F spacecraft, as it was known before launch, was designed and built by TRW Systems Group, Inc. JPL developed three instruments that flew on the spacecraft: Magnetic Fields, S-Band Occultation, and Celestial Mechanics, as well as running the Deep Space Network which provided tracking and data system support. Caltech was responsible for the Jovian Infrared Thermal Structure experiment. Pioneer was very successful, crossing the orbit of Mars and the asteroid belt beyond it, encountering, studying, and photographing Jupiter, then crossing the orbits of Saturn, Uranus, and Neptune. It left the solar system in 1983 and has been contacted several times in the past few years. As of July 2001, the spacecraft was still able to send a return signal to Earth. At Jupiter, the experiments of Pioneer were used to examine the environmental and atmospheric characteristics of the giant planet. Pioneer was also the vital precursor to all future flights to the outer solar system. It determined that a spacecraft could safely fly through the asteroid belt. It also measured the intensity of Jupiter's radiation belt so that NASA could design future Jupiter (and other outer planets) orbiters. |

MODIS Land Cover of Asia

MODIS Land Cover of Asia |
| Abstract |
New NASA satellite-generated land cover maps are providing scientists with a detailed picture of the distribution of Earth's ecosystems and land use Scientists can better determine how vegetation is distributed and land is being used around the world with new NASA satellite-generated land-cover maps. These new maps, based on a global digital database of land cover types Earth images that is updated every 16 days, will help scientists better understand the Earth's climate and carbon budget and climate, through closer monitoring of water and land resources, including forested and agricultural areas. These land-coverland cover maps were developed at Boston University in Boston, MA, using data from the Moderate-resolution Imaging-Spectroradiometer (MODIS) instrument aboard NASA's Terra satellite. The prototype MODIS maps were created with data acquired between July and December 2000, but future maps will utilize one year of data. Advances in remote sensing technology allow MODIS to collect higher-quality data than previous sensors, yielding the most detailed land cover classification maps to date. The new maps are better because the quality of MODIS data is much higher than AVHRR data. They are also more current because the information content of MODIS data allowed scientists to exploit more efficient automated methods for categorizing land cover than was were previously possible, reducing the time to generate maps from months or years to about one week. Each MODIS land-coverland cover map contains 17 different land cover types, differentiating among eleven natural vegetation types such as deciduous and evergreen forests, savannas, grasslands, permanent wetlands and shrublands. Agricultural land use , as well as, several categories of land surfaces with little or no plant cover -- such as bare ground, urban areas and permanent snow and ice -- are also depicted in the maps. The data product is available at (http://edcdaac.nasa.gov) |

Erythemal Index for August 2
…
| Title |
Erythemal Index for August 2000 through July 2001: Slow Zoom to North America (With Dates) |
| Abstract |
The Erythemal Index is a measure of ultraviolet radiation (UV) at ground level on the Earth. UV exists to the left of the visible spectrum and is divided into three components (UV-A, UV-B and UV-C). UV-B (290-320 wavelengths) is the most dangerous form of UV radiation that can reach ground level. Atmospheric ozone shields life at the surface from most of the harmful components of solar radiation. Chemical processes in the atmosphere can effect the level of protection provided by the ozone in the upper atmosphere. This thinning of the atmospheric ozone in the stratosphere leads to elevated levels of UV-B at ground level and increases the risks of DNA damage in living organisms. |

Daily Erythemal Index over the United States for July 2001 |
| Abstract |
The Erythemal Index is a measure of ultraviolet radiation (UV) at ground level on the Earth. UV exists to the left of the visible spectrum and is divided into three components (UV-A, UV-B and UV-C). UV-B (290-320 wavelengths) is the most dangerous form of UV radiation that can reach ground level. Atmospheric ozone shields life at the surface from most of the harmful components of solar radiation. Chemical processes in the atmosphere can effect the level of protection provided by the ozone in the upper atmosphere. This thinning of the atmospheric ozone in the stratosphere leads to elevated levels of UV-B at ground level and increases the risks of DNA damage in living organisms. |
