Planet to asteroid belt

[3488]

433 Eros has turned out to have diverse surface types ranging from flat to hilly, <br />smooth to rocky, and monotonously cratered to unique in character.<br /><br />This picture was taken for "optical navigation," that is, plotting the spacecraft's <br />course by tracking the positions of the landmarks below. <br />It caught a spectacular view of a horizon sculpted by worn, degraded craters <br />and punctuated by jagged boulders. The angular boulder at the center of the <br />frame is about 60 meters (197 feet) tall, or two-thirds the length of a football field.<br />Angular rocks are very common in nature; the corners form as a rock is <br />chipped out of a larger mass.<br /><br />This image was taken May 18, 2000, from an orbital altitude of 50 kilometers (31 miles). <br />The whole scene is about 1.4 kilometers (0.8 miles) across, and it shows <br />features as small as 4 meters (13 feet).<br /><br />Built and managed by The Johns Hopkins University Applied Physics Laboratory, <br />Laurel, Maryland, NEAR was the first spacecraft launched in NASA's <br />Discovery Program of low-cost, small-scale planetary missions. <br />See the NEAR web page at http://near.jhuapl.edu for more details. <br /><br />NASA / JHU.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

A particularly interesting landform on 433 Eros is the long ridge that wraps around most <br />of the asteroid's northern hemisphere. NEAR Shoemaker's digital camera <br />captured part of that ridge just after local sunrise on May 20, 2000, from an orbital <br />altitude of 50 kilometers (31 miles). The whole scene is about 1.4 kilometers (0.8 miles) <br />across, and it shows features as small as 4 meters (13 feet). This part of the ridge is <br />up to 250 meters (820 feet) wide, but both the width and the height of the feature <br />vary along its length. <br />The large number of superimposed craters indicates that the ridge is a relatively old feature.<br /><br />Built and managed by The Johns Hopkins University Applied Physics Laboratory, <br />Laurel, Maryland, NEAR was the first spacecraft launched in NASA's Discovery <br />Program of low-cost, small-scale planetary missions.

This is the last image of asteroid 433 Eros received from NEAR Shoemaker. <br /><br />Taken from a range of 120 meters (394 feet), it measures 6 meters (20 feet) across. <br />What we can see of the rock at the top of image measures 4 meters (12 feet) across. <br /><br />The streaky lines at the bottom indicate loss of signal as the spacecraft touched down<br />on the asteroid during transmission of this image.<br />Built and managed by <br />The Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, <br />NEAR was the first spacecraft launched in NASA's Discovery Program of low-cost, <br />small-scale planetary missions.

Asteroid 5535 Annefrank is a permanent memeber of the Main Asteroid Belt between<br />Mars & Jupiter.<br /><br />Asteroid 5535 Annefrank is seen as irregularly shaped, cratered body in an image <br />taken by NASA's Stardust spacecraft during a flyby of the asteroid.<br /><br />Stardust came within about 3,300 kilometers (2,050 miles) of the asteroid as a <br />rehearsal for the spacecraft's encounter with its primary target, comet Wild 2, in January 2004. <br />The camera's resolution was sufficient to show that 5535 Annefrank is about <br />8 kilometers (5 miles) in length, twice the predicted size from Earth-based observations. <br />The surface reflects about 0.1 to 0.2 percent of sunlight, slightly less than anticipated. <br />A few craters that are hundreds of meters across can be seen. <br />The straight edge in the right side of the image may be an artifact of processing.<br /><br />Stardust will bring samples of comet dust back to Earth in 2006 to help answer <br />fundamental questions about the origins of the solar system. <br />Additional information about the mission is available online at <br />http://stardust.jpl.nasa.gov. Lockheed Martin Astronautics, Denver, <br />Colo., built and operates the Stardust spacecraft. <br /><br />Stardust is a part of NASA's Discovery Program of low-cost, highly focused <br />science missions.
