  3. HST SM4 Flight Crew Megan McArthur Scott Altman Greg Johnson Drew Feustel Mike Massimino Mike Good John Grunsfeld

  4. HST Launch on Need (LON) Rescue Mission STS-400 STS-400 is being prepared as the rescue mission for STS-125. It will be processed in parallel with STS-125 and will be available for launch if needed

  5. HST Servicing Mission 4 (SM4) Configuration Multi-use Logistic Equipment Carrier Flight Support System Orbital Replacement Unit Carrier Super Lightweight Interchangeable Carrier

  6. SI C&DH (Bay 10) SI C&DH

  7. WFC3 will be the first Hubble wide-field camera spanning Ultraviolet – Visible - Infrared

  8. Battery Bays (2 & 3) Bays 2 and 3 Bays 3 Bays 2

  9. Battery Details

  10. Rate Sensor Unit (RSU) HST Rate Gyro Assembly (RGA) Rate Sensor Unit and Electronic Control Unit

  11. COS will be the most sensitive UV spectrograph ever to fly on Hubble

  12. ACS Worksite CCD Electronics Box (CEB) Radiators

  13. ACS Worksite/Tools Grid – To Be Cut Cover Plate (32 Non-Captive Fasteners) View from bottom of ACS looking up

  14. GridCutter

  15. Fastener Capture Plate

  16. Card Removal from ACS Card Extraction Tool

  17. ACS Repair CEB Replacement Module Power Supply Module Power Connectors

  18. Fastener Capture Plate L-Handle EVA Handle Cover Clamp LVPS-2 Card (Internal) MEB Cover The Fastener Capture Plate is attached to the STIS MEB cover and is used to capture the 111 screws that EVA astronauts will remove in order to gain access to the failed LVPS-2 power supply card STIS

  19. Low Voltage Power Supply (LVPS) Card

  20. STIS Card Removal

  21. FGS R&R Access to HST Access to FSIPE

  22. Soft Capture Mechanism The Soft Capture Mechanism will be attached to the aft bulkhead of Hubble during SM4. It greatly increases the likelihood of a successful autonomous rendezvous and capture. It is a risk reduction opportunity for a future de-orbit mission EM Soft Capture Mechanism (SCM) Fitcheck with Lightweight Berthing and Positioning System (BAPS) ring SCM attached to HST
