This is what the Mars Science Laboratory (MSL) represents. Experimental, explorational science. Learning about Mars as a new world. Discovering new things that will tell us about the history of our solar system, help reveal the secrets of life, and continue blazing the trail that may someday be traveled by the rest of us.

Space is a laboratory, an experiment in all forms of all things, an infinity of possibilities, properties, and places that cry out for investigation and exploration.

By reigniting the exploration role of our government Lewises and Clarks within and enabled by the infrastructure and economic drive of commercial space and the people themselves, this nation can rise to heights unimaginable.

The exploration of space: Be it by humans or robots, based on the best choice for the mission and the most efficient means to return the data and science sought. Most of the time, this will mean we send robots due to cost and danger. But sometimes, we will need the irreplaceable judgment and descriptive abilities of a person on the spot.

The problem is not that the U.S. economy won't be able to take care of its citizens - it is that taking away benefits, creating intergenerational warfare, and scapegoating will make for very difficult and bad politics. This is a tragedy that we can see coming. Early action would be relatively painless.

We associate the North Atlantic with cod. The motto of Newfoundland used to be 'In cod we trust.' It was a joke, but it was essentially true. But there is no cod anymore. And that's extraordinary. It's all because of either greed or politics - Canadian politics.

There is no question that the federal government sometimes overdoes it in issuing rules and regulations.

The Establishment Clause prohibits government from making adherence to a religion relevant in any way to a person's standing in the political community.
