Solar System Technologies Explored
THE SMALL
BUSINESS INNOVATION RESEARCH (SBIR) program at the Jet Propulsion
Laboratory (JPL) is supporting a number of small companies to develop
new technologies intended for enhanced solar system exploration.
It is hoped that some day these technologies may result in new products
and discoveries that will enhance our lives.
In Situ Exploration and Sample Return is a new SBIR technology
development initiative to help collect the vast amount of information
required before scientists can provide a reasonable description
of the nature of our solar system or be able to tell whether life
previously existed on Mars or Jupiter's moon, Europa. Recent discoveries
that indicate the possibility of ancient life on Mars and possible
underground bodies of water on Europa have given a new sense of
adventure and urgency to this work, according to Byron Jackson,
program support manager at JPL.
The goals are significant overall cost and risk reduction of future
science missions while reducing the need for ground control operations
and communications facilities. The miniaturization of multiple spacecraft
and landers, rather than a single large spacecraft, will enable
future science missions to explore the planets, moons and asteroids
of our solar system.
The first demonstration of new technology will occur as part of
the Mars Surveyor Lander mission launched in January. Two microprobes
have been designed to piggyback on the mission, utilizing its communications
system to relay information on weather and soil chemistry back to
Earth. Each probe weighs only two kilograms (about 4.5 pounds) and
consists of a penetrator instrument package and an aeroshell to
protect it during its descent to the surface of Mars. Upon impact,
the penetrator will pierce the aeroshell and bury itself in the
Martian soil, where it will perform in situ soil experiments.
Technologies supported by SBIR contracts in the area of in situ
exploration include: lasers operating at appropriate ultraviolet
and visible wavelengths to enable nondestructive nucleic and amino
acid detection with a miniature detector; a micro balloon probe
for aerial photography based on a self-inflating zero-pressure (the
point that limits pressure as a system's temperature approaches
absolute zero) polyethylene balloon; and a control strategy for
robotic systems that is calibration free, robust, highly accurate
and suitable for sampling and retrieval tasks. These represent only
a few of the innovations the NASA SBIR program is supporting that
will enhance our ability to explore the solar system.

Launch pad workers prepare
the Mars Global Surveyor spacecraft before it lofted into space
in January 1999. Technologies being developed to continue the Surveyor
mission are showing commercial promise.

Technologies with potential
commercial applications are being developed for explorations beyond
the Mars Surveyor mission.
