5 . Hotels orbit Saturn’s pale orange moon, Titan. Cruise ships roam the docking stations like fish. Have you ever imagined making this future space travel in the fiction films a reality?     1    

Large companies and entire governments have teamed up to make space travel and exploration easier and quicker. Several countries are planning space missions between now and 2025. Some aim to build stations orbiting the moon.     2     Eventually, they maybe build settlements there!

Yet no human has traveled beyond Earth’s orbit since 1972. Money is part of the problem. To put a pound of anything in space costs about $10,000. Consider that the old NASA space shuttles carried 2.2 million pounds (998,000kg) of fuel alone. Once in space, we face the problem of enormous space. Current technology and fuels can propel spacecraft at around 36,000 miles (58,000 km) per hour.     3     Therefore, Human astronauts need some sort of new engine technology. Without it, they would not likely live long enough to complete journeys to other worlds.

    4     Some human astronauts live and work in the International Space Station(ISS). They’re in small spaces far from home. They suffer mentally and emotionally. Moods sour. Depression kicks in. Clear thinking muddies. Fear runs high.

Accessing fresh food is another issue. Today, astronauts eat lots of freeze-dried meals.

    5     We need those to be healthy. Of course, space doesn’t have grocery stores. Deep-space travelers may need to grow food on board. Unfortunately, good nutrition cannot fully protect an astronaut. All that time spent floating affects bones, muscles, and the blood. The body suffers damage from radiation streaming from stars and supernovas.

6 . At twenty-three, I had no idea that a summer class I feared would change my life and help me achieve dreams.

Even bigger __________ were brought to life after that. I wrote more books and got picked up by one of the five publishers. Life may bring us a big surprise. Sometimes, the things we fear the most will eventually become the things that change us for the __________.
