HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science
DAILY REPORT # 3592 PERIOD COVERED: DOY 105 OBSERVATIONS SCHEDULED ACS/HRC/WFC 10060 CCD Daily Monitor This program consists of basic tests to monitor, the read noise, the development of hot pixels and test for any source of noise in ACS CCD detectors. This programme will be executed once a day for the entire lifetime of ACS. ACS/WFC 9744 HST Imaging of Gravitational Lenses Gravitational lenses offer unique opportunities to study cosmology, dark matter, galactic structure, galaxy evolution and quasar host galaxies. They are also the only sample of galaxies selected based on their mass rather than their luminosity or surface brightness. While gravitational lenses can be discovered with ground-based optical and radio observations, converting them into astrophysical tools requires HST. We will obtain ACS/WFC V and I images and NICMOS H images of 21 new lenses never observed by HST and NICMOS H images of 16 lenses never observed by HST in the IR. As in previous cycles, we request that the data be made public immediately. ACS/WFC/WFPC2 9822 The COSMOS 2-Degree ACS Survey We will undertake a 2 square degree imaging survey {Cosmic Evolution Survey -- COSMOS} with ACS in the I {F814W} band of the VIMOS equatorial field. This wide field survey is essential to understand the interplay between Large Scale Structure {LSS} evolution and the formation of galaxies, dark matter and AGNs and is the one region of parameter space completely unexplored at present by HST. The equatorial field was selected for its accessibility to all ground-based telescopes and low IR background and because it will eventually contain ~100, 000 galaxy spectra from the VLT-VIMOS instrument. The imaging will detect over 2 million objects with I 27 mag {AB, 10 sigma}, over 35, 000 Lyman Break Galaxies {LBGs} and extremely red galaxies out to z ~ 5. COSMOS is the only HST project specifically designed to probe the formation and evolution of structures ranging from galaxies up to Coma-size clusters in the epoch of peak galaxy, AGN, star and cluster formation {z ~0.5 to 3}. The size of the largest structures necessitate the 2 degree field. Our team is committed to the assembly of several public ancillary datasets including the optical spectra, deep XMM and VLA imaging, ground-based optical/IR imaging, UV imaging from GALEX and IR data from SIRTF. Combining the full-spectrum multiwavelength imaging and spectroscopic coverage with ACS sub-kpc resolution, COSMOS will be Hubble's ultimate legacy for understanding the evolution of both the visible and dark universe. NIC1/NIC2/NIC3 8792 NICMOS Post-SAA calibration - CR Persistence Part 3 A new procedure proposed to alleviate the CR-persistence problem of NICMOS. Dark frames will be obtained immediately upon exiting the SAA contour 23, and every time a NICMOS exposure is scheduled within 50 minutes of coming out of the SAA. The darks will be obtained in parallel in all three NICMOS Cameras. The POST-SAA darks will be non-standard reference files available to users with a USEAFTER date/time mark. The keyword 'USEAFTER=date/time' will also be added to the header of each POST-SAA DARK frame. The keyword must be populated with the time, in addition to the date, because HST crosses the SAA ~8 times per day so each POST-SAA DARK will need to have the appropriate time specified, for users to identify the ones they need. Both the raw and processed images will be archived as POST-SAA DARKSs. Generally we expect that all NICMOS science/calibration observations started within 50 minutes of leaving an SAA will need such maps to remove the CR persistence from the science images. Each observation will need its own CRMAP, as different SAA passages leave different imprints on the NICMOS detectors. NIC3 9999 The COSMOS 2-Degree ACS Survey NICMOS Parallels The COSMOS 2-Degree ACS Survey NICMOS Parallels. This program is a companion to program 9822. STIS/CCD 10018 CCD Dark Monitor-Part 2 Monitor the darks for the STIS CCD. STIS/CCD 10020 CCD Bias Monitor - Part 2 Monitor the bias in the 1x1, 1x2, 2x1, and 2x2 bin settings at gain=1, and 1x1 at gain = 4, to build up high-S/N superbiases and track the evolution of hot columns. STIS/CCD 10023 STIS CCD Spectroscopic Flats C12 Obtain CCD flats on the STIS CCD in spectroscopic mode WFPC2 10070 WFPC2 CYCLE 12 Supplemental Darks Part 2/3 This dark calibration program obtains 3 dark frames every day to provide data for monitoring and characterizing the evolution of hot pixels. FLIGHT OPERATIONS SUMMARY: Significant Spacecraft Anomalies: (The following are preliminary reports of potential non-nominal performance that will be investigated.) HSTAR 9376: GS Acquisition (1,3,3) @ 105/13:51:31Z ended in FL backup on FGS 3 due to SSLE on FGS 1 @ 105/13:55:03Z and again @ 105/13:56:57Z. Under investigation. COMPLETED OPS REQs: 17121-1 - TMDIAG Monitoring of Compensated MSS Data @ 105/1611z 17123-0 - FSW 2.5B RAM Installation @ 105/1649z 17125-0 - Load OBAD SPC Macro @ 105/1802z 17122-0 - FSW 2.5B On-Orbit Verification @ 105/2310z OPS NOTES EXECUTED: None SCHEDULED SUCCESSFUL FAILURE TIMES FGS GSacq 15 15 FGS REacq 3 3 FHST Update 19 19 LOSS of LOCK SIGNIFICANT EVENTS: Successfully completed FSW 2.5b in RAM load @ 105/17:19Z (OR 17123 with attached IP-54 script). RAM loads were completed @ 105/13:54Z and the FSW was activated @ 10-5/14:49Z. Successfully completed post-installation memory dump and best estimate @ 105/16:49Z. FSW compared this dump with pre-installation dump. Telemetry was monitored for two orbits following FSW 2.5b activation and everything was nominal. Successfully loaded TMDIAGs to monitor MSS-1 (MSSCMP, MSSCMP1, MSSCMP2) and MSS-2 (MSSCMP3, MSSCMP4, MSSCMP5) compensated data @ 106/16:11Z (OR17121-1). This data will provide verification of the 10 Hz output and an initial understanding of the data for PCS analysis processing. Subsequently selected PN Format periods allowed monitoring of the data at high rate to develop a better understanding of the performance issues associated with the magnetic field changes in TGS M2G mode. The new Magnetic Field data correctly tracked the MTS-Compensated MSS-2 telemetry. All of the new TGS data showed the correct default states. Successfully loaded, dumped, and compared OBAD SPC Macro @ 105/18:02Z (OR 17125 with attached IP-059 script). PCS SEs will be executing an on-orbit verification script (OR 17122 with attached script) to verify FSW 2.5b, this macro must be loaded prior to beginning the on-orbit verification. The one FHST Rate Control period monitoring using FHST 1 was initiated @ 105/19:35Z and operated nominally. All relevant TGS telemetry updated as expected. FSW 2.5b EEPROM installation first opportunity 106/11:54Z - 12:24Z (OR 17124 with attached IP-55 script). EEPROM load dump and compare scheduled 106/12:34Z - 13:16Z. Rate Control Monitoring, PN Format data acquisition scheduled 106/16:55:31Z - 17:25:31Z (OR 17122 with attached FSW 2.5b On-orbit Verification script). Rate Control Monitoring, OBAD Combo (FSHT 2/FHST 1) scheduled 106/19:35:49Z - 19:57:30Z. OBAD Combo (FHST 1/FHST 2) scheduled 106/21:11:45Z - 21:30:00Z. |
