Hubble is As Powerful As Ever Deep, precise, stable pan-chromatic imaging Slitted and slitless spectroscopy, coronagraphy, astrometry Mysteries of dark matter and dark energy Architecture of the universe Life stories of galaxies Births and deaths of stars Recipes for building planets STScI Calibration Workshop - August 2014

  3. Current Status Infrared WFC3/IR 2014 • All science instruments are performing well • ACS, COS, STIS, and WFC3 are being used for science • Observatory subsystems in excellent working order • Cycle 21 is progressing as planned • October 1, 2013 – September 30, 2014 • Cycle 22 programs selected • Nominal start on October 1, 2014 • Already observing now for a small number of programs • 24thAnniversary on April 24, 2014 • Kicks off Hubble’s 25th year Visible WFPC2 2001 STScI Calibration Workshop - August 2014

  10. -------------------- Monday, May 25, 2009 Monday, August 11, 2014 If all works as planned, Hubble should be able to peer even deeper into space and farther back in time than it has before. The telescope, circling some 350 miles above Earth, is expected to perform for at least five more years. That should be long enough to bridge the gap until its successor, the James Webb Space Telescope, is sent to a perch almost a million miles from Earth. STScI Calibration Workshop - August 2014

  11. Hubble 2020 Vision Statement Operate Hubble out to 2020 or beyond so that there is at least one year of overlapping science observations with the James Webb Space Telescope, performed in a manner that maximizes the science return of both observatories by taking full advantage of Hubble's unique capabilities and the astronomical community's scientific curiosity. • An operating observatory • Capable science instruments • Scientific drivers (demand) • Adequate staffing and user support • Appropriate funding • Teamwork (multi-level) How long will Hubble continue to operate? As long as it remains scientifically productive What is needed to keep Hubble scientifically productive? STScI Calibration Workshop - August 2014

  12. The Road to 2020+ STScI Calibration Workshop - August 2014

  13. Observatory Status STScI Calibration Workshop - August 2014

  14. HST Gyro Locations – SM4 Rate Sensing Units STScI Calibration Workshop - August 2014

  15. Gyro 5 • On March 7, 2014 Gyro 5 failed • Failure was expected following a flex lead failure on February 22 • Gyro 5 has “standard” flex lead • Not a mission lifetime limiting event • HST has 6 gyros • Well-developed plan is in place for eventual failure of any gyro • Continue in 3-gyro mode as long as possible to maximize science Flex Lead HST 64-PM Fluid Floated RIG Rate Gyro Electronics Control Unit (ECU) Flex Lead Heaters Rate Sensor Unit (RSU) STScI Calibration Workshop - August 2014

  16. Subsystem Reliability • NASA Engineering and Safety Center (NESC) reliability estimates for Hubble’s instruments and primary subsystems support a 2020 vision. • The recent failure of Gyro 5 does not substantively change the overall gyro lifetime assessment. Instruments Subsystems STScI Calibration Workshop - August 2014

  17. Hubble Science Output • 12,303 science papers based on HST data, with more than 525,000 citations • 13,327 individuals have (co)authored a paper based on HST data • More than 500 PhD theses have been based on HST data Refereed Papers per Year Year of Publication STScI Calibration Workshop - August 2014

  18. Intense Proposal Pressure • For Cycle 22 there were 1135 proposals submitted • >6000 different investigators have had approved programs to date Number of Proposals per Cycle Cycle Post-SM4 STScI Calibration Workshop - August 2014

  19. High Scheduling Efficiency 60 % Efficiency 50 40 Weekly calendars Mar 2013 Feb 2014 STScI Calibration Workshop - August 2014 • Science program scheduling is challenging • Large programs with strict timing/orientation constraints (e.g., Frontier Fields) • Parallel observations (coordinated and pure) • Targets of opportunity (~150 activated since SM4) • Quick-turnaround DD programs (rare/high-impact science opportunities) • Scheduling efficiency of 50% is substantially higher than original goal of ~35%

  20. HST Budget ($98.3M) Grants to Observers GFSC Flight Operations & Sustaining Engineering 29% Cy18 – $27.7M Cy19 – $28.4M Cy20 – $30.1M Cy21 – $28.6M 33% Operations staff is half the size it was ~12 years ago STScI EPO 4.5% STScI Science Operations 33.5% Note: Even a flat funding profile of $98.3M per year will require reductions in personnel or cuts to science grant funding.
