1. Hubble’s planetary mission Max Mutchler STScI Research and Instrument Scientist Bonnie Meinke STScI Outreach Scientist Hubble Science Briefing 2 April 2015

2. Hubble has been good for planetary science – and vice versa • Hubble is capable of observing almost any moving target in the Solar System, with a quick response to transient events • Best of both worlds: Hubble has a strong history of supporting (and sometimes inspiring) planetary missions • Hubble’s superb sensitivity and resolution are ideal for studying small Solar System bodies or features • Important planetary observations have happened at critical points in the Hubble mission

3. Moving targets require special tracking, observation planning, and data processing Jupiter 24 Jan 2015

4. Moving targets require special tracking, observation planning, and data processing Jupiter 24 Jan 2015

5. Pre-launch hype, delays, and ground system development (including moving-target tracking)

7. HST launch on 24 April 1990

8. Hubble’s cameras

9. Hubble was deployed • and serviced by • the Space Shuttle • 1990 Launch • 1993 SM1 • 1997 SM2 • 1999 SM3A • 2002 SM3B • SM4 • The Trouble with Hubble

10. This is the new era of astronomy?

13. Top Ten Hubble Telescope Excuses 10. The guy at Sears promised it would work fine. 9. Some kids on Earth must be fooling around with a garage door opener. 8. There's a little doohickey rubbing against the part that looks kind of like a cowboy hat. 7. See if you can think straight after 12 days of drinking Tang. 6. Bum with squeegee smeared lens at red light. 5. Blueprints drawn up by that "Hey Vern!” guy. 4. Those damn raccoons! 3. Shouldn't have used G.E. components. 2. Ran out of quarters. 1. Race of super-evolved galactic beings are screwing with us.

14. Solar System observations helped fill the void until the first HST Servicing Mission (SM1) Despite bugs, breakdowns, and its famous mirror flaw, Hubble still gives a clear view of the cosmos - sometimes

17. Comet Shoemaker-Levy 9 (SL9) is disrupted by Jupiter, and on course for a collision in 1994! The stage is set…

18. Hubble was deployed • and serviced by • the Space Shuttle • 1990 Launch • 1993 SM1 • 1997 SM2 • 1999 SM3A • 2002 SM3B • SM4 • The comeback story begins

19. The first Hubble Servicing Mission (SM1) in Dec 1993 was effectively a rescue mission WFPC2 was installed

20. Wide Field Planetary Camera 2 (WFPC2) images had a strange shape due to the high resolution planetary camera (PC) Wide Field 2 (WF2) Wide Field 3 (WF3) Planetary Camera (PC1) Wide Field 4 (WF4)

21. Comet Shoemaker-Levy 9 impacts Jupiter in July 1994, providing a showcase for the repaired Hubble’s capabilities

23. Hubble observations of Saturn 1996-2000 As Saturn takes its 29-year journey around the Sun, its tilt allows us to see its rings from different perspectives.

24. Hubble was deployed • and serviced by • the Space Shuttle • 1990 Launch • 1993 SM1 • 1997 SM2 • 1999 SM3A • 2002 SM3B • SM4 • New instruments STIS and NICMOS provide ultraviolet (UV) and infrared (IR) capability.

28. Hubble was deployed • and serviced by • the Space Shuttle • 1990 Launch • 1993 SM1 • 1997 SM2 • 1999 SM3A • 2002 SM3B • SM4 • Getting the hardware up and running again

29. Hubble was deployed • and serviced by • the Space Shuttle • 1990 Launch • 1993 SM1 • 1997 SM2 • 1999 SM3A • 2002 SM3B • 2009 SM4 • Advanced Camera for Surveys is installed, providing greater sensitivity and resolution

30. Advanced Camera for Surveys (ACS): installed in 2002…failed in 2007… and partially repaired in 2009

31. Advanced Camera for Surveys Wide Field Planetary Camera 2 ACS / WFC ACS / HRC (High Resolution Channel)

32. Hubble observations of giant planets (and their rings and moons) Without probes exploring these planets, Hubble is the best tool for exploring the outer solar system.
