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.

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.

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.

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.
