SUBJECT: Space Transportation System Enhancement Study
Presidential Directive/NSC-42 calls for an interagency
task force to make recommendations by August 1, 1979, on
what future space transportation system capabilities will
be needed. Dr. Press has asked the Department of Defense
and NASA to co-chair this Task Force; Dr. Hans Mark, Under
Secretary of the Air Force, and Dr. A. M. Lovelace, Deputy
Administrator of NASA, have agreed to lead this important
study of incremental improvements to the basic Shuttle
transportation system.
As a first step, DoD and NASA have identified ?these areas
.as requiring early attention:
The basic Shuttle orbiter is limited by its on-
board electrical power system. This limitation
.placed operational constraints on Shuttle orbital
stay times.as well as--on the design of integral
Shuttle payloads. Preliminary studies have.already
identified-a number of candidate approaches to
increase the electrical power available-to Shuttle
and Shuttle payloads. It would be very helpful.if
interested agencies would outline their.:?oreseeable
space power requirements over the next ten :to
fifteen years for integration into the study.

2. The Shuttle system as presently configured will
require.some thrust augmentation capabilities in
order to meet its specified performance envelope.
While the minimum thrust augmentation'-required,is
established by currently programmed missions,_it
would be helpful to receive potential future payload
weight and orbit projections from the interested
agencies to factor into the study.
needed over the next fifteen years.
3. The orbiter's integral Remote Manipulation System
.provides only.a limited capability for manipulation
of paylaods in space. A number of important on-orbit
activities are now being identified that may require
an extension of these capabilities, such as remote
on-orbit maintenance, repair, or refueling. it
would be useful to have the views of the interested
agencies on those on-orbit capabilities felt to be
4. At. present, the Shuttle system includes the IUS
and the SSUS's as propulsive stages. Future
.missions may require additional capabilities for
propulsion and new operational flexi.bilities such
as reusability.
These initial study areas do not, of course, represent the
full spectrum.-of.potential additional capabilities that could
be considered in the evolution of.space transportation;
interested -agencies ?are invited to outline other specific
foreseen . needs- that. the Task Force should study.

It would be appreciated if the agencies desiring to partici-
pate would develop and document their views on these topics
and, at the same time, identify a senior-agency representa-
tive to-the Task Force. Communications on this matter-should
be addressed to either Dr. Lovelace or to Dr. Mark, with a
copy to the other.
