## Have access to all types of propellant delivery containers
Crew is trained in system operation and equipment is fully operational
Have successfully loaded five NASA spacecraft:
MAP spacecraft on June 3-4, 2001, at KSC
CONTOUR spacecraft on June 6, 2002, at KSC
MESSENGER spacecraft June 29-July 2, 2004, at ASO
Pluto New Horizons spacecraft Dec 4, 2005, at KSC
THEMIS – five spacecraft Jan 4, 2007, at ASO
Next mission is STSS scheduled for June 2008

## KSC Fueling Services Summary

- Customer provides spacecraft requirements
- Propellant OBQ, filter size, interface connections, temperature and pressure limits, etc
- KSC provides service equipment and procedures to meet those requirements
- Load propellants and pressurants
- Contingency offload at loading facility and pad
- Customer participation is encouraged for all planning and operations activities
- Afterward, KSC servicing equipment is prepared to support the next mission

- For NASA Internal Use Only

## Scales Data

- Mettler-Toledo Electromagnetic Force Compensation-type scales
- Intrinsically safe electronics plug into facility UPS power
- All stainless steel construction
- Large scale:  6000 kg capacity w/ 0.6 kg accuracy
- Use with GPTU, 120 gal DOT 4BW or DOT 110 cylinders
- Deck space ~ 5’ x 7’
- Small scale:  600 kg capacity w/ 0.04 kg accuracy
- Use with 55 gal and smaller DOT 4BW cylinders
- Deck space ~ 39”x32”

- For NASA Internal Use Only

## Pressure/Vacuum Panel Data

- Full GN2 or GHe pressure control
- Oil-less vacuum pump
- Pressurize fuel container to load spacecraft  tank
- Fill pressurant tank with GN2 or GHe up to ~5500 psig
- Can be used to leak test propulsion system
- For N2O4 loading, use basic “suitcase” PPRU for 500-psi helium source

- For NASA Internal Use Only

- April 6, 2007

## Re-designed Liquid System

- Separate panels dedicated to fuel and N2O4 service
- 1.0 micron canister filter element
- Includes a sample, vacuum, & drain port
- Use with any sized DOT 4BW cylinder or a GPTU
- Only part of GSE exposed to fuel or oxidizer
- Multiple copies for multi-program support

- Prototype filter assembly

- For NASA Internal Use Only

## Summary

- KSC has developed a generic spacecraft fueling system and supporting services
- GSE & OMIs conform to rigorous NASA design and certification requirements
- The service is mobile; can fuel a spacecraft at KSC, VAFB, or other location
- NASA missions may use the KSC service thus avoiding the high cost of creating their own capability
