Development and testing of the X-38 is broken into
multiple phases,
and Dryden participation is planned for the first four phases. Each phase utilizes existing

the project lead, has designed this approach to implement a "pay as you go" philosophy. The
following paragraphs summarize each of the first four phases.
Table I is provided to summarize the various aspects of each of the four phases.
The concept of the parachute recovery system is illustrated in
