(a) Lunar and planetary exploration

A Day for Planetary Justice

Barbarically, we're killing sharks for shark fin soup, undermining food chains that shape planetary chemistry and drive the carbon cycle, the nitrogen cycle, the oxygen cycle, the water cycle our life support system.

But we have a planetary emergency.

Now, the Saturn system is a rich planetary system.

We cannot expand anymore, because it erodes the planetary boundaries.

And those planetary systems are going to be very common.

First of all, there was no theory of planetary rings.

What are the planetary boundaries within which we can safely operate?

A simple interactive program for playing with simulations of planetary systems

What is the exact relationship between levels of greenhouse gases and planetary temperatures?

This is an actual group of people that sit around naming planetary objects.

They can try and see if they can have a broader planetary bargain.

He had a good theory of planetary rings and how the solar system operated.

Mars had rivers, Mars had lakes, but more important Mars had planetary scale oceans.

There's actually a little read out down there of our planetary atmosphere, pressure and temperature.

The model produced a story of Venus similar to the evolution previously hypothesized by planetary scientists.

It's going to be everywhere we look where there are planetary systems that can possibly support it.

And this man with a planetary sized brain is now serving a 13 year sentence in California.

And this is a measure of how much well being we get for our planetary resource use.

You're mad. I'll drive. I know I can drive.

For this purpose, it develops and operates sounding rockets, satellite launchers, scientific satellites, planetary probes and scientific balloons.

In other planetary exploration, the Magellan spacecraft, launched in May 1989, determined that Venus is still geologically active.

So without a theory of planetary rings and with only grainy data, you can't have a good theory.

In just over two years of operations, we've found over 1,200 potential new planetary systems around other stars.

So most people have no idea of the difference between like, an emission nebula and a planetary nebula.

The drive for transparency must become a drive for consistency.

Drive slowly.

Drive carefully.

Drive safely.

Drive on.

Now this is the Big Bang equivalent then of human development within the safe operating space of the planetary boundaries.

Data from this instrument show planetary scale disturbances in upper atmospheric weather corresponding to one or two waves around the globe.

It's also good news, because the planetary risks we're facing are so large, that business as usual is not an option.

And could we even define a planetary boundary, a fence, within which we then have a safe operating space for humanity?

Our sun is one of 400 billion stars in our galaxy, and we know that many other stars have planetary systems.

Planetary systems outside our own are like distant cities whose lights we can see twinkling, but whose streets we can't walk.

It was during this period that the cycle of dietary and planetary destruction began, the thing we're only realizing just now.

You drive down.

Please drive carefully.

Can you drive?

Can anyone drive?

Tom cannot drive.

She can't drive.
