ViSBARD: Insights into the S

| Title |
ViSBARD: Insights into the Sun-Earth Connection |
| Abstract |
ViSBARD (Visual System for Browsing, Analysis, and Retrieval of Data) is a data analysis application that brings together measurements from collections of spacecraft near the Earth or throughout the heliosphere In this visualization created from ViSBARD screenshots, we see the magnetic field as measured from six different satellites. The position of each spacecraft is marked by a small color glyph (ACE = yellow, Cluster = dark blue, Geotail = green, GOES 10 = red, Polar = light blue, Wind = purple). The direction of the arrow signifies the direction of the magnetic field while the color represents the intensity (red being the highest, blue the lowest). The magnetic pole of the Earth is in yellow, and it rotates properly as the animation proceeds. This view of the magnetic storm shows highly disturbed fields at geosynchronous orbit (GOES), many crossings of the 'magntotail current sheet' where the field changes sign and points at the opposite pole of the Earth, close encounters with the Earth (large red fields that are truncated to keep the arrows from becoming huge), and the entry from the back of the picture of Wind and Geotail through the bow shock (wire-frame) and magnetopause (sometimes visible as a transparent surface). |

| Title |
Cosmic Rays and Supernova Dust |
| Explanation |
Cosmic Rays [ http://imagine.gsfc.nasa.gov/docs/features/topics/snr_group /cosmic_rays.html ] are celestial high energy particles traveling at nearly the speed of light, which constantly bombard the Earth. Discovered during [ http://antwrp.gsfc.nasa.gov/apod/ap961016.html ] high altitude balloon flights in 1912 their source has been a long standing mystery. But a recent theory suggests [ ftp://pao.gsfc.nasa.gov/pub/pao/releases/1998/98-083.htm ] that cosmic ray particles are atomic nuclei [ http://cst.lanl.gov/CST/imagemap/periodic/periodic.html ] blasted from dust grains formed in supernovae, the death explosions of massive stars. This artist's illustration shows [ ftp://PAO.GSFC.NASA.GOV/newsmedia/CRT/EJECTA.TXT ] a supernova explosion (at left) and a conical section of the expanding cloud of ejected material. Atoms are torn from the brownish bands of "dust" [ http://antwrp.gsfc.nasa.gov/apod/ap980104.html ] material by shock waves (represented by orange rings). The shocks in the expanding blast wave [ http://antwrp.gsfc.nasa.gov/apod/ap980217.html ] then accelerate the atoms to near light speeds firing them into interstellar space like cosmic bullets. The theory is supported by observations indicating that high velocity dust was formed in the nearby supernova 1987A [ http://zebu.uoregon.edu/~soper/StarDeath/sn1987a.html ], and that Beryllium, a light element created in Cosmic Ray collisions, is found equally in both old an young stars. NASA's Advanced Composition Explorer [ http://www.srl.caltech.edu/ACE/ ] (ACE) satellite can also test details of the theory by directly measuring Cosmic Rays. |

| Title |
MISR Participates in Aerosol Characterization Experiment over Asia |
| Original Caption Released with Image |
Before scientists apply new spacecraft measurements to global climate change research, they must carefully test their understanding of the data under controlled conditions. During April 2001, a team of 200 investigators from 11 countries participated in the Aerosol Characterization Experiment (ACE) field campaign in Asia, deploying instruments aboard several ships, aircraft, and island stations in the waters surrounding Japan and Korea. They characterized meteorological conditions, measured the atmospheric energy balance, and directly sampled airborne dust and pollution particles while the Multi-angle Imaging SpectroRadiometer (MISR) and other satellite instruments flew overhead. These MISR images, centered just north of Shikoku Island in southwest Japan, were acquired on April 13, 2001 during Terra orbit 7015. They are two of nine simultaneous views obtained at different angles by the instrument, at 26 degrees aft of vertical (left) and 60 degrees forward of vertical (right). The entire west end of Honshu Island, which crosses the upper half of the images, is covered with broken clouds. Away from the clouds, the atmosphere looks hazier in the steeper MISR view, such differences reveal information about particles in the atmosphere. As these images were taken, the U.S. National Oceanographic and Atmospheric Administration (NOAA) Research Vessel Ron Brown and the National Science Foundation (NSF)/National Center for Atmospheric Research (NCAR) C-130 aircraft probed the environment near Oki island, in the upper left part of the images. At the same time, the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) Twin Otter aircraft made atmospheric chemistry and heat-balance measurements in the bottom-center region of the images. For more about ACE-Asia, see http://saga.pmel.noaa.gov/aceasia/ [ http://saga.pmel.noaa.gov/aceasia/ ] MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology. |
