NASA yesterday completed its Record of Decision (ROD) on the X-33 Environmental Impact Statement (EIS), announcing it intends to proceed with the preferred X-33 flight test program as described in the Final EIS issued Oct. 3.

Signing of the decision document yesterday by Dr. Robert E.

Whitehead, NASA Associate Administrator for Aeronautics and

Space Transportation Technology, concludes a 12-month EIS

process of assessing the development and flight test of the

X-33, a subscale technology demonstrator prototype of a

Reusable Launch Vehicle.

All 15 test flights of the X-33 will be conducted from the

launch site at Haystack Butte on the eastern portion of Edwards

Air Force Base, CA, to landing sites at Michael Army Air Field,

Dugway Proving Ground, UT, and Malmstrom Air Force Base near

Great Falls, MT.

A third landing site, Silurian Lake, a dry lake bed near

Baker, CA, had been considered for use as a short-range landing

site. However, flights into Dugway¿s airfield some 450 miles

from Edwards better match the initial flight demonstration

requirements.

The X-33 environmental study considered issues such as

public safety, noise, impacts on general aviation, and effects

on biological, natural and other resources. Two launch sites

and five landing sites were evaluated for potential use. The

final decision on a flight test program was based on

programmatic, technical, and other considerations as well as

environmental factors. Overall, environmental impacts of the

program are expected to be low at all operational sites.

Now that the environmental process for the X-33 has been

completed, the next major program milestone is groundbreaking

for the launch facility at Edwards Air Force Base.

Construction crews are scheduled to begin work this week.

Construction is scheduled to be completed within a year.

The X-33 is being developed under a cooperative agreement

between NASA and Lockheed Martin Skunk Works, Palmdale, CA,

which began July 2, 1996.

NASA has budgeted $941 million for the X-33 program through

1999. Lockheed Martin will invest at least $212 million in the

X-33 program.

The X-33 is a sub-scale technology demonstrator prototype

of a Reusable Launch Vehicle, which Lockheed Martin has named

"Venture Star ™," and which the company hopes to develop

early in the next century. Through demonstration flights and

ground research, the X-33 will provide information needed for

industry to decide by the year 2000 whether to proceed to the

development of a full-scale, commercial single-stage-to-orbit

reusable launch vehicle.
