Huygens Probe Shines for Cassini's Cameras
http://saturn.jpl.nasa.gov/news/pres...cfm?newsID=521
Huygens Probe Shines for Cassini's Cameras December 27, 2004 (Source: Jet Propulsion Laboratory) The European Space Agency's Huygens probe appears shining as it coasts away from Cassini in this close-up of an image taken on Dec. 26, 2004, just two days after it successfully detached from the Cassini spacecraft. Shown here side-by-side is a close-up of the Huygens probe. The image on the left shows the relative size of the probe. The bright spots in both images are probably due to light reflecting off the blanketing material that covers the probe. Although only a few pixels across, this image is helping navigators reconstruct the probe's trajectory and pinpoint its position relative to Cassini. This information so far shows that the probe and Cassini are right on the mark and well within the predicted trajectory accuracy. This information is important to help establish the required geometry between the probe and the orbiter for radio communications during the probe descent on January 14. The Huygens probe, built and managed by ESA, will remain dormant until the onboard timer wakes it up just before the probe reaches Titan's upper atmosphere on Jan. 14, 2005. Then it will begin a dramatic plunge through Titan's murky atmosphere, tasting its chemical makeup and composition as it descends to touch down on its surface. The data gathered during this 2-1/2 hour descent will be transmitted from the probe to the Cassini orbiter. Afterward, Cassini will point its antenna to Earth and relay the data through NASA's Deep Space Network to JPL and on to the European Space Agency's Space Operations Center in Darmstadt, Germany, which serves as the operations center for the Huygens probe mission. From this control center, ESA engineers will be tracking the probe and scientists will be standing by to process the data from the probe's six instruments. This image was taken with the Cassini spacecraft narrow angle camera at a distance of 52 kilometers (32 miles) from the probe on Dec. 26, 2004. The image has been magnified and contrast enhanced to aid visibility. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL.

What kind of picture is that? It doesn't show anything! Why won't
NASA release any "real" photos of the separation, not 12 hours after? Anyone else find this strange? |
