SpaceDev and Boeing Team on Commercial Deep-Space Missions

Lunar, Mars and Asteroid Missions to be Assessed

Poway, Calif., and Huntington Beach, Calif., February 1, 2000 —
SpaceDev, Inc. (OTCBB: SPDV), the world’s first commercial
space exploration and development company, and The Boeing
Company (NYSE: BA), the world’s largest aerospace company,
announced today that they have teamed together to investigate
opportunities of mutual strategic interest in the commercial deep-
space arena.

Under terms of an agreement recently approved by the companies,
the Boeing Space and Communications Group will team with
SpaceDev’s Space Missions Division to investigate a variety of
small, low-cost, deep-space mission initiatives formulated by
SpaceDev.

In coming months, technical and corporate staff from each
company will further refine and advance SpaceDev’s concept of
commercial missions to the Moon, Mars and near-Earth asteroids,
involving micro-spacecraft of 250 kg mass. The effort also includes
a global assessment of the market potential for such missions, and
a technical and programmatic assessment of launch-vehicle
options for such missions.

“I believe that the next major ‘New New Thing’ will be the no-holds
barred, explosive opening of space by the private sector and the
convergence of space with the Internet, providing huge amounts of
unique content and the largest Internet audience delivery
mechanism to date,” said Jim Benson, SpaceDev Chairman and
CEO. “We are very pleased that Boeing has decided to join us in
looking at the business case for trailblazing missions to
commercially and scientifically explore the territory of the inner
solar system. We look forward to working with the experienced
Boeing team to help get these unique and historic missions off the
ground,” Benson said.

SpaceDev has been refining the design of its commercial Near
Earth Asteroid Prospector (NEAP) mission since 1997 and started
offering commercial, fixed-price Mars probe-carrier and Moon
orbiter missions with real-time streaming video last year. In
November 1999 the company competitively won a contract from
University of California, Berkeley to design, build, integrate, test
and operate the CHIPSat astronomy micro-spacecraft, NASA’s first
University-Class Explorer (UNEX) mission to proceed into the
implementation phase.

Commenting on the agreement with SpaceDev, Rick Stephens,
Boeing vice president and general manager for Reusable Space
Systems, said, “Boeing recognizes the potential for the
commercial exploration of space and we applaud SpaceDev’s
entrepreneurial efforts in paving new inroads in this emerging
market area. This collaborative effort will allow us to substantiate
the projected market demand for commercial deep space missions
and jointly develop future market-driven solutions to meet this
demand.”
