1.0 INTRODUCTION

1.1 Policy

This document defines explicitly, or by reference, the Space Shuttle Program (SSP) authorized
requirements to be implemented on the STS-300 Launch on Need (LON) Crew Rescue flight.
Products generated to satisfy these requirements shall meet the schedules defined in the Flight
Definition and Requirements Directive (FDRD), NSTS 07700 Volume III, and in the appropriate
Integration Plans (IP’s).

1.2 Flight Objective

The primary objective of the Launch on-Need (LON) Crew Rescue flight is to return a stranded
STS-114 crew of 7 from the International Space Station (ISS) safely to earth within 90 days of
this declared contingency. The LON flight would utilize the STS-121 vehicle (OV-104)/payload
configuration without any payloads. The minimum turnaround from LON callup is 35 days. This
is driven by pad turnaround with only one pad available (which is the case for ’04 and early ’05),
the standard Flight Design I-Load Uplink/Day of Launch (DOL) processes, and training
requirements.

The payload bay will be configured without any payloads, but some residual cargo integration
hardware may remain on the LON flight. The crew compartment will be configured with
additional seats to support the return of up to 11 crewmembers.
