We're taking capability from NASA that used to cost billions of dollars, and we're doing it for tens of millions of dollars. We want to learn that critical information necessary to develop those resources.

Our mission is to expand the economic sphere of influence of humanity off the surface of the planet and into the solar system. Currently we have a vibrant economy in space that goes out to the geostationary belt- where the communication satellites are- and it stops.

The design and collaborative power of an individual engineer or technologist is more powerful than it's ever been. The tasks themselves are getting more accessible too. Putting a robotic spacecraft out into space is becoming fairly routine.

Water is the essence of life. On Earth it's used to grow plants and within industrial processes but in space it takes on a whole new form. We can use water as a radiation shield. One cubic metre of water gives the same protection as Earth's atmosphere and magnetosphere. Water is a molecule made of hydrogen and oxygen- and that happens to be rocket fuel.

There are very few African-American men in this country who haven't had the experience of being followed when they were shopping in a department store. That includes me... And there are very few African-American men who haven't had the experience of walking across the street and hearing the locks click on the doors of cars.

Race and guns, both of which have conspired not only to take the life of a teenager, but to make that killing entirely permissible. I can't look an African-American parent in the eye for thinking about what they must tell their sons about what can happen to them on the streets of their country.

Trying to figure out how we fit into the cosmos is old, it's a basic human question.

Although, today, the universe appears more bio-friendly than it ever was. That doesn't mean it is inhabited. We still have to prove that.

The iron in the haemoglobin in your blood was cooked up in the heart of a massive star that blew up about 8 billion years ago. We understand now in pretty good detail, how intimately connected we are with the cosmos.

What makes SETI different today is that instead of the verb "to believe" we're trying to use the verb "to explore". We want to see what's actually out there instead of just believing what someone tells us is out there.

There is a naïve form which doesn't recognise the bubble, and thinks that real-estate will go up forever. There is then a second order overconfidence where someone recognises a bubble but feels they will escape it when other people don't.
