“Dr, Pooshwa, over here.” The head of the entire Mars operation motioned for Dr. Pooshwa to follow her. “I want to show you where you’ll be working. This is Dr. Cranden. He’s been here for five years already.”
A thin, middle aged man with long, curly hair pulled into a ponytail stepped forward. “I am so excited to see what you brought with you. Look at this space we have." The scientists stepped into a huge room that was enclosed with thick plastic.
enclosed
“These etrees have been growing for four years,” Dr. Cranden stated. He led his partner to the side of the room. “The room has an exhaust system right above these trees. Once a day, we open the system and let the oxygen that the plants have created out into the atmosphere. Our goal is to make this system large enough to change the composition of the atmosphere. The etrees you have brought are smaller, but more advanced. They will increase the output of oxygen by 300 percent."
composition
Dr. Pooshwa raised her eyebrows and surveyed the room. “That’s a huge job,” she said with a sigh.
“Yes, but this project is just beginning. We have plans to build four more rooms like this one and then the whole area will be enclosed by a dome. The dome will be permeable, so we can control the flow of the different gases into and out of the environment. It’s a very long-term project.” Two of the scientists who arrived today have already begun building the dome.
permeable
“I know that the head of the mission wants us to have the first dome in place in 10 years, so that people can begin to settle here,” Dr. Pooshwa stated. “I’m not sure we can work that fast.”
“Don’t forget that we’ve already got 45 people working up here now,” Dr. Cranden assured her. “Another group should be arriving in a month and the scope of the project will just keep getting bigger and bigger.
“Let’s get started then,” Dr. Pooshwa smiled.”I’ll program the conveyor robots to bring all the boxes in here.

A good athlete knows the importance of a good uniform. The of the uniform needs to allow the athlete to move freely without becoming too hot or cold. The fabric must be in order to make sure that sweat does not become trapped on the athlete’s skin. The uniform must also make sure that the muscles are not too tightly. It seems like making an athletic uniform is easy, but the of the project is actually quite extensive.
