| Title |
Spitzer's Delicate Ring Flower |
| Description |
NASA's Spitzer Space Telescope finds a delicate flower in the Ring Nebula, as shown in this animation. The outer shell of this planetary nebula looks surprisingly similar to the delicate petals of a camellia blossom. A planetary nebula is a shell of material ejected from a dying star. Located about 2,000 light years from Earth in the constellation Lyra, the Ring Nebula is also known as Messier Object 57 and NGC 6720. It is one of the best examples of a planetary nebula and a favorite target of amateur astronomers. The "ring" is a thick cylinder of glowing gas and dust around the doomed star. As the star begins to run out of fuel, its core becomes smaller and hotter, boiling off its outer layers. Spitzer's infrared array camera detected this material expelled from the withering star. Previous images of the Ring Nebula taken by visible-light telescopes usually showed just the inner glowing loop of gas around the star. The outer regions are especially prominent in this new image because Spitzer sees the infrared light from hydrogen molecules. The molecules emit infrared light because they have absorbed ultraviolet radiation from the star or have been heated by the wind from the star. |

Severe Storms Trigger Floods in Bangladesh |
| Description |
Heavy rains over an 8-day span from the 12th through the 20th of April 2004, brought widespread flooding to the Sylhet region in northeastern Bangladesh when the Surma and Kushiyara rivers crested above flood stage. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center monitors rainfall over the global tropics. MPA rainfall totals for the period 12-20 April 2004 show almost 2 feet of rain (darkest red areas) fell over the Khasi Hills, foothills of the Himalayan Mountains, in the northeastern Indian providences of Assam and Meghalaya. A widespread area of 8-inch rainfall extends from eastern Bangladesh through northeastern Indian and over northern Myanmar (Burma). Such heavy rainfall this time of the year is unusual as the typical rainy season runs from June to September. TRMM is a joint mission between NASA and the Japanese space agency JAXA.

Buttes in Memnonia |
| Original Caption Released with Image |
20 April 2004 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows three small buttes in the Memnonia Sulci region of Mars near 10.5°S, 176.1°W. The buttes are remnants of formerly more extensive layered rock that once covered the region. The larger butte has several dark slope streaks formed by downslope movement (landsliding/avalanching) of dust. The picture covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the left. |

MSIP: Elysium Mons Crater |
| Original Caption Released with Image |
Released 20 April 2004 The image of a crater near Elysium Mons was captured from the 2001 Mars Odyssey Spacecraft, at 16:47 Mars Local Time, on November 23, 2002. The image is 18km x 54km, Lat. 21.6N, Long. 137.21E, Sun Angle of 64.13 degrees, 6,746.4 seconds into orbit, and with a camera filter centered at about 650nm. The Westview Astronomy Research Team is a group of 25 students from Westview High School who wrote a scientific proposal to NASA, JPL, and Arizona State University Mars Flight Research Facility. The proposal was accepted and we worked for several months researching the background of exploration for water and life on the planet Mars. The team conducted trial experiments involving rock propulsion and several activities identifying surface features on Mars. We worked with Mars scientists to target and upload an image from the 2001 Mars Odyssey Spacecraft. The image was successfully acquired and viewed for the first time ever by our team. The image was dedicated to Westview High School in the name MSIP. Image information: VIS instrument. Latitude 18.1, Longitude 136.3 East (223.7 West). 19 meter/pixel resolution. NASA and Arizona State University?s Mars Education Program is offering students nationwide the opportunity to be involved in authentic Mars research by participating in the Mars Student Imaging Project (MSIP). Teams of students in grades 5 through college sophomore level have the opportunity to work with scientists, mission planners and educators on the THEMIS team at ASU?s Mars Space Flight Facility, to image a site on Mars using the THEMIS visible wavelength camera. For more information go to the MSIP website: http://msip.asu.edu [ http://msip.asu.edu ]. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time. NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. The Thermal Emission Imaging System (THEMIS) was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena. |
