Grade 7: Unit 2

He felt submerged in a chemical that could dissolve his intellect and burn away his past.

Dark she was, and golden-eyed, burnt almost black by the sun, sleeping, and the children metallic in their beds, and the wind roaring forlorn and changing through the old peach trees, the violet grass, shaking out green rose petals.

"It's hot. The children want to swim in the canals and hike. Please come along."

There was only an immense staring burn upon the land.

He saw the sky submerged above him, the sun made Martian by atmosphere and time and space.

They strolled on old mosaic paths, beside still pumping fountains.

Silence after rapid dialogue can heighten suspense.

But because of the causes of chronic boredom, scientists say, research facilities in Antarctica might actually provide a better simulation of the stress of a journey to Mars.

More important, Danckert and Kring say, bored people are also prone to taking risks, subconsciously seeking out stimulation when their environment bores them.

It’s just you, the people you came in with, no way out and little to break up the monotony.

It suggests that what we call a restless mind is just that—a mind desperate for something to amuse it, searching frantically for stimulus.

An important lesson that Antarctica can impart on a Mars expedition is this: even scientists on important missions can get excruciatingly bored.

It would be catastrophic if humanity's greatest voyage were brought low by the mind's tendency to wander when left to its own devices.

Mars may be one of the closest planets humans want to colonize, but it certainly isn't the only one.

Funded by NASA's Ames Research Center and the Defense Advanced Research Projects Agency (DARPA), the 100-Year Starship project aims to develop the tools and technology necessary to build and fly a spaceship to another planetary system within the next 100 years.

The program isn't necessarily concerned with building the ship itself as much as it seeks to foster innovation and enthusiasm for interstellar travel.

People used to go out, but the outside environment was threatening, so hardly anyone (she looked at him carefully now), hardly anyone ever used it now.

The podmaster had said that trees had been extinct for hundreds of years.

Some amazing mutation must have occurred, making it possible for at least some creatures to breathe the outside atmosphere and drink its poisoned water.

Carla’s math teacher encouraged her to do extra credit work because of Carla’s aptitude for math.

Carla thinks that studying calculus is challenging but fascinating.

Then, when the routines are set up, you cede that to private enterprise.

We live in a capitalistic society. That's how it works.
