Ever Wonder What's Beyond?

Every Wonder Whats Beyond???

Lets go on a journey...

This is a travel guide for the Journey to Outer Space

After doing some critical thinking, the scientists have finally come up with a name for our shuttle, POLA-Ris!

This is rough sketching of POLA-Ris' journey.

1) Launching!!

The mixture of gases from both SRBs and ET are burned in a combustion chamber. The combination of thrust from the SRBs and that provided by the engines accelerates the shuttle to a speed of about 28000 km and sends it into orbit 300 - 530 km above the earth.

2 a) The SRB Seperation.

2 minutes after the launch, the SRB separates from the ET at an altitude of 45km and parachute back to earth while the orbiter's engines continue firing.

2 b )The ET Seperation

The ET seperates from the orbiter the following 6 minutes and falls to earth, burning up in the atmosphere along the way.

3) Orbit

A pair of orbital manoeuvring system (OMS) engines fire to send the orbiter into low orbit. Later , the OMS engines fire again to place the orbiter in a higher circular orbit.

4) Retro-fire

Then, when returning to earth, the orbiter is first flown in reverse. Engines called thrusters are then fired to slow it down.

5) Re-Entry

The craft is turned forward to re-enter the atmosphere with a crucial position at an angle between 28* and 38*. (*= degree)

During this time, the ceramic tiles will insulate the orbiter protecting it and its crew. There is no radio contact for at least 12 minutes when the hot ionized gasses surrounds the orbiter.

6) Approach

The flight computer reduces its speed as it approaches the runaway.

7) Landing

The commander then takes over from the computer and deploys the landing gear.

The orbiter touches down at a speed of 350km and a parachute assist the rapid slowing down of the craft.

Well, this is actually our last project for the year and so I decided it would be great to share it with my fellow readers. We did a good job getting an "A" for our assignment and so it is.

Thanks again to those involved.
