By some estimates, the oil you recently discovered off the shores of Brazil could amount to twice the reserves we have in the United States. We want to work with you. We want to help with technology and support to develop these oil reserves safely, and when you're ready to start selling, we want to be one of your best customers.

It is my firm belief that it will be in the interests of the United States, especially our economic interests, to pursue comprehensive immigration reform.

By 2025 we expect new spacecraft designed for long journeys to allow us to begin the first ever crewed missions beyond the Moon into deep space. So we'll start by sending astronauts to an asteroid for the first time in history. By the mid-2030s I believe we can send humans to orbit Mars and return them safely to Earth. And a landing on Mars will follow and I expect to be around in see it.

The best way to not feel hopeless is to get up and do something.
