HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT      #4852 PERIOD COVERED: 5am May 22 - 5am May 26, 2009 (DOY 142/0900z-146/0900z) OBSERVATIONS SCHEDULED S/C/FGS 11457 Verify Guide Star Acquisition with Continuing FGSs After the shuttle deploys HST at the end of SM4 and at the beginning of SMOV4, it will be necessary to test and demonstrate HST's ability to acquire guide stars with the FGSs. This is a major pre-requisite for all observations by HST's SIs ...Continue Reading

WFPC2 11327 Red Leaks The aim of this program is to measure the red leaks in the 8 WFPC2 UV??? filters (F122M, F300W, F255W, F218W, F185W, F170W, F160BW, F122M). We will use red crossing ...Continue Reading
