## Space Shuttle Program Manifest & Flight Opportunities for Small Payloads

**1999 Shuttle Small Payloads Symposium**
**NASA/JSC**
**MT3/Anne E. Sweet**

## Agenda

**Today’s manifest environment**
**Customer and Flight Integration Office**
**Opportunities and concepts**
**ISS flights**
**Non-ISS flights**
**New research flights**
**Conclusion**

## Today’s Manifest Environment

**For next 5 years, almost 90% of the funded flights are for ISS**
**Possible, but difficult to get small payload opportunities on ISS flights**
**Opportunities identified early are at risk of being bumped**
**Opportunities identified late would be very restrictive**
**ISS flights thru mid FY02 will have severe thermal environment**

## Today’s Manifest Environment(Cont’d)

- Today’s Manifest Environment(Cont’d)

**Opportunities on non-ISS flights are limited in number**
**Dedicated research missions--one (STS-107)--fully manifested**
**HST servicing missions in FY01 and FY03-- projected to be performance limited**
**Reimbursable (unfunded) flight placeholders exist on the manifest, however there are no confirmed customers**

## Space Shuttle Customer and Flight Integration Office

**Mission Statement:**
**The Customer & Flight Integration Office will enable the development and implementation of a meaningful manifest for the Space Shuttle Program**

## Opportunities on ISS Flights

**Process developed to allow identification of potential opportunities**
**done with preliminary data**
**based on volume and performance margin**
**Flags the need for early evaluation of shuttle capabilities in those locations**
**Can then decide whether any payload preparation strategies would be prudent**
**Payloads manifested no later than L-11 months**

## Opportunities on ISS Flights(Cont’d)

- Opportunities on ISS Flights**(Cont’d)**

**Opportunities may arise when small portions of ISS hardware get shuffled**
**Preliminary proposal to provide a capability to manifest standard GAS experiments late in flow**
**Manifest potentially as late as L-5 months**
**This proposal still in its infancy**

## Opportunities on Non-ISS Flights

**STS-107 fully manifested**
**Attempting to accommodate as many payloads as possible**
**Extensive evaluation and analysis has been done **
**Reimbursable placeholders**
**No confirmed customers**
**However, potential opportunities for small payloads could materialize on such flights**

## Additional Science & Research Missions

**Manifest concepts have been proposed that would enable additional science and research flights**
**“****Stand-by Research” mission**
**Designed to take advantage of any significant slips in the ISS assembly**
**Research flight developed in parallel with manifested ISS flight**
**Decision points at L-9 months and 30 days prior to orbiter vehicle reconfiguration for flight**

## Additional Science & Research Missions(Cont’d)

- Additional Science & Research Missions(Cont’d)

**Conversion of funded ISS Launch-On-Need flights to “Stand-by cargo” flights**
**Create funded research missions on OV-102 where ISS LON flights are manifested**
**Move LON flights to the ISS orbiters (OV-103, -104, -105)**
**LON flights handled using the processes developed for the Stand-by Research concept**

## Conclusion

**We are the payload’s advocate.**
**It is part of our mission to make sure we make the most efficient use possible of the Space Shuttle’s resources.**
**Our office is committed to making every effort to find opportunities for short-duration science and research technology in low-Earth orbit.**
