What do we say about ….. ?

Law in space? …. Law and Metalaw

Planetary protection

What do we protect? Why? … life? landscape? archaeology?

“The Overprotection of Mars”

Human or robotic explorers?

Terraforming – good, bad, obligatory, unavoidable?

Mining asteroids and the Moon

Private property in space?

What do we say about ….. ?

Invasive science

Mars One – human rights?

Colonising the universe – why?

Does why matter?

What laws will suit a colony on Mars?

Contact with aliens - rules? Protecting us, protecting them

Law in space?

Law and Metalaw

Attorney Andrew G. Haley in 1956

Peter Household – the ethics of space exploration

“ The reach of legal discourse may be constrained by the boundaries of the territory, terrain or ‘space’ within which legal rules apply and their enforcement is feasible. However, outer space, in all its unexplored and unknown vastness, is not susceptible to these constraints imposed by the puny hands of human law.

“ But as we probe that vastness, we human beings take with us ethical frames of reference whose scope and relevance far exceed the bounds of legal frontiers. ”

Marcio Barbosa, Deputy Director-General of UNESCO, 29 October 2004

Asteroid mining

Jim Benson, Chairman of the Space Development Corp, 1997

“ After landing, we will ‘stake’ any mining and patent claims we believe to be possible, and then will simply declare ownership of the trillion-dollar asset. This will help draw attention to the need to establish private property rights in space. ”

“ We humans have a burning desire to increase ourunderstanding of everything around us, but we are accountable to future generations of scientists to explore our solar system without destroying the capability of others to conduct their own investigations. ”

When biospheres collide, Michael Meltzer, NASA 2011.

Peter Household – the ethics of space exploration

New Scientist editorial July 2013

“ Is there a case for relaxing the rules? Perhaps. If Mars has its own life, it should be different enough from Earth life for us to recognise it. If it doesn't, any bugs we find will be recognisably terrestrial. In either case, Earth life will struggle to colonise Mars. Recent arrivals are unlikely to thrive in the harsh conditions, and the possibility of them outcompeting any natives is about as likely as parrots colonising Antarctica and ousting the penguins ….

New Scientist editorial July 2013

But …

“ If a spacecraft crashed or melted through Europa's shell into the ocean beneath, it could have fatal consequences for everything living there. The only thing worse than not finding life – if it is there – would be finding it after we've destroyed it.”

Article IX of the 1967 Outer Space Treaty

“… parties to the Treaty shall pursue studies of outer space including the Moon and other celestial bodies, and conduct exploration of them so as to avoid their harmful contamination and also adverse changes in the environment of the Earth resulting from the introduction of extraterrestrial matter and, where necessary, shall adopt appropriate measures for this purpose …”

COSPAR says …

– life, including extra-terrestrial life, has special ethical status and deserves appropriate respect because it has both intrinsic and instrumental values

and

– non-living things, including extraterrestrial things, likewise have value and deserve respect appropriate to their instrumental, aesthetic or other value to human or extraterrestrial life.

Why do we protect? What do we protect?

Terraforming

Terraforming

Why do we value Mars?

• as a park ?

• as a lab ?

• a location for a new society ?

• a source of minerals ?

• an enterprise zone ?

• a lifeboat ?

Peter Household – the ethics of space exploration

Terraforming

What is our ethical obligation?

1. To preserve Mars to same degree we seek to protect Earth’s environment?

2. To keep it pristine? Why?

3. What if there is no life on Mars?

Humans in space

7. Manifest destiny

“ We have crossed all the mountains; we have penetrated all the oceans. We have plumbed the atmosphere to its height and the oceans to their depths. Unless we are willing to settle down into a world that is our prison, we must be ready to move beyond Earth, and I think we are ready. We have the technological capacity to do so; all that we need is the will. ”
