ACS Status: February 21, 2007The ACS Solar Blind Channel (SBC) has been reactivated using the ACS Side-1 electronics. Procedures to return the SBC to service proceeded normally on February 19 and 20. The SBC is performing as expected, and initial analyses of flat field images obtained after activation indicate that contamination of the ACS optics and SBC detector window as a result of the outgassing event after the Side-2 failure is minimal. The first SBC science observations after reactivation were obtained on February 20 in support of the New Horizons flyby of Jupiter. Additional SBC science and calibration observations are scheduled for the next several weeks. Now that the SBC is operating nominally, the remaining Cycle 15 SBC observations will be executed as the HST observing schedule allows. The ACS Wide Field Channel (WFC) and High Resolution Channel (HRC) remain inoperable at the present time. The Anomaly Review Board investigating the Side-2 failure is considering options for on-orbit tests to help pinpoint the location of the failure and clarify what might be needed during SM4 to restore the CCD channels to service. |
