The first spacecraft designed to capture 3-D "stereo" views of the sun and solar wind have been shipped from the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., to NASA Goddard Space Flight Center (GSFC) in Greenbelt, Md., for their next round of pre-launch tests. http://www.stereo.jhuapl.edu/ |

no updates in this topic since october, but actually, very interesting things had happened last week:
QUOTE December 4, 2006: The SECCHI team opened the doors to the SECCHI SCIP-A instruments and took a few first-light images. Everything went absolutely smoothly. The three doors opened without incident. The first images look great even though they were sent down highly compressed to keep the downlink time reasonable. The EUVI was opened first and an image from each of the four quadrants looked fine - no major tears or pinholes in the front filters. The sun is close to being in the center of the CCD, and the resolution is beautiful. Then we opened COR2 and took an image--also beautiful, although there is a slight offpoint (which we expected). The exposure time is just about where we expected, about 3-4 seconds. We then took a pB sequence of 3 images with the result that streamers could be seen all the way to the edge of the field. Then COR1 was opened and it was also as expected. A pB sequence shows the inner corona nicely out to about 2.5 R, which is what we expected. (and even more news at http://stereo-ssc.nascom.nasa.gov/new.shtml) so i am eager to see new pics, especially ones from December 7, when enourmous solar flare had been taken place. PS First lunar swinby is scheduled for December 15. |
