A Mission To Alpha Centauri

this is a re-wright. after reading over it i realized it was bad and a lot of it made no sense. i hope it reads better now.
earth space force sent a ship to the Alpha Centauri. when they arrived what they found was not what they expected. they meet an Alien race whose king was obsessed with earth.

For the last one hundred and fifty years a lot has changed around the world. Most countries have combined into larger countries. The Americas consist of what was once the United States, all south America, Canada, Cuba. and all the Caribbean.
Space travel has been possible for over three hundred years. Mars has been terraformed and has a large colony living there. There are bases on the moon and manned missions in our solar system happen every day.
Now it has been decided that it's time to go beyond our system and explore other star systems. Now the largest ship ever is built using new technology making it faster than any other.
Admiral McGregor Sir, it's time for the press conference. Commander Willams and Captain Miller are waiting for you on stage.
Thank you, sergeant, let's get this over with so we can get back to work. I want that ship to launch on time.
Admiral McGregor 62 years old with white hair standing 5 foot 11 inches tall with a muscular build that even at his age can still out due most younger men. He has served in the space force for 44 years and made the comment he will never retire. He can be very stern at times but is also fair.
We are here today to update you on the upcoming mission into deep space. Space force was founded over a hundred and fifty years ago. We have sent manned missions to every part of our solar system. This will be our first mission to go outside our system. We are only days away from launching our first interplanetary spacecraft.
