To get into the atmosphere, the To get into the atmosphere, the rocket fires the main rocket rocket fires the main rocket booster and two of the smaller booster and two of the smaller rocket boosters. The 2 small rocket boosters. The 2 small rockets that were used to get out rockets that were used to get out of the atmosphere run out of fuel, of the atmosphere run out of fuel, but they stay on the rocket. but they stay on the rocket.

Since the main rocket boosters Since the main rocket boosters still has fuel it takes the ship still has fuel it takes the ship to the moon. When the rocket gets to the moon. When the rocket gets close enough, it fires its smaller close enough, it fires its smaller rocket toward the moon. When it rocket toward the moon. When it impacts it is more powerful.impacts it is more powerful.

A computerized system to control A computerized system to control the rocket by Navigators will be the rocket by Navigators will be installed. installed.

The unmanned spacecraft will The unmanned spacecraft will contain solar panels to help re-contain solar panels to help re-energize the spacecraft. While in energize the spacecraft. While in space the solar energy will power space the solar energy will power the ship throughout its journey. the ship throughout its journey. The rocket itself will be made out The rocket itself will be made out of titanium.of titanium.

The Apollo 2009 will take The Apollo 2009 will take approximately seven days to reach approximately seven days to reach the moon. It will take four days the moon. It will take four days to orbit the Earth twice and to orbit the Earth twice and three days to get to the moon. We three days to get to the moon. We are going to enter the transfer are going to enter the transfer orbit at an angle. (see map photo orbit at an angle. (see map photo at the left).at the left).

It will orbit the moon 40 times It will orbit the moon 40 times so it will take 80 days to orbit. so it will take 80 days to orbit. Then it will impact the moon’s Then it will impact the moon’s North Pole Region at a 65 degree North Pole Region at a 65 degree angle.angle.

satellite chip and thrusters. We satellite chip and thrusters. We will have the chip inside the will have the chip inside the rocket and the satellite on Earth. rocket and the satellite on Earth. The satellite will locate the The satellite will locate the rocket by locating the chip and rocket by locating the chip and indicate the location of the indicate the location of the rocket.When the rocket gets off rocket.When the rocket gets off course we will locate it then we course we will locate it then we will use the thrusters. If the will use the thrusters. If the thrusters don’t work we will use thrusters don’t work we will use the Hohmann Transfer,(Orbital the Hohmann Transfer,(Orbital Maneuver). The Hohmann transfer Maneuver). The Hohmann transfer orbit is part elliptic orbit, that orbit is part elliptic orbit, that will connect the Earth’s orbit and will connect the Earth’s orbit and moons orbit. That will allow the moons orbit. That will allow the spacecraft to travel through these spacecraft to travel through these connected orbits.connected orbits.

In addition, it will have a chip In addition, it will have a chip installed in it. We will also use a installed in it. We will also use a GPC, (General Purpose Computer). A GPC, (General Purpose Computer). A satellite will pick-up the signal satellite will pick-up the signal sent from the chip. The satellite sent from the chip. The satellite will send the information it will send the information it gathers to a computer. The computer gathers to a computer. The computer will show the original course to will show the original course to the moon and the course that the the moon and the course that the rocket will be currently on rocket will be currently on throughout the mission.throughout the mission.
