Question:
What is Life's Future on Earth and Beyond?
Planetary
Protection
Objective 17: Refine
planetary protection guidelines and develop protection technology for
human and robotic missions.
Within the coming decade, significant
advances in astrobiology are likely to come from from many sources --
remote sensing, in situ experiments, sample return missions, and
Earth based research. We can anticipate that this new information about
physical, chemical and geological environments on planets, planetary satellites,
and other Solar System bodies will provide important details related to
the origin, evolution, nature, and evolutionary potential for living entities
on Earth and elsewhere. During this period of intense exploration and
research, there will be a continuing need to apply planetary protection
principles to avoid scientifically and biospherically harmful cross contamination
of the planets and celestial bodies. Such planetary protection controls
must meet NASA and COSPAR policies, satisfy technical and scientific concerns,
and reassure the public that appropriate safeguards will be taken at every
step of exploration.
Implementation
Near- to mid-term:
- Conduct an international conference
to discuss the ethical issues associated with planetary protection.
- Assess the risk and potential
impact of importation of alien life to a planet.
- Develop the knowledge base
and recommendations for implementation plans and policies for human
exploration.
- Review and recommend refinements
to planetary protection policies and guidelines for robotic solar system
exploration that incorporate the latest scientific information and technological
advances.
- Enlist the aid of a broad
contingent of international experts to explore ethical and theological
questions related to the existence of extraterrestrial life, the potential
for harmful cross contamination, and the implications of long-term,
large-scale space and planetary exploration, habitation and engineering.
- Develop methodologies, taking
advantage of the latest technologies, to aid in the implementation of
planetary protection for robotic missions. These will include containment
and isolation on Earth, life detection, cleaning and sterilization.
Future extensions:
- Understand the risk for cross-contamination
of life throughout the solar system.
- Develop new or refined technologies
necessary to avoid harmful cross contamination during human exploration.
- Develop and deploy new technologies
to sense life and its diversity, to guide our exploration of the universe.
