What does T6 mean?
The T6 refers to the temper or degree of hardness, which is achieved by precipitation hardening. This grade has a good strength-to-weight ratio and is also heat-treatable. With great formability and weldability, it is used for engineering and structural applications, boats, furniture, and more.
What happens to a Space Shuttle once it launches?
The two orbital maneuvering systems’ (OMS) engines are located in pods on the aft section of the orbiter, one on either side of the tail. These engines place the shuttle into final orbit, change the shuttle’s position from one orbit to another, and slow the shuttle down for re-entry.
How much would it cost to launch a Space Shuttle?
For launching the Space Shuttle, which weighs about 2,000 tonnes, the cost is about $800 million USD, or nearly a billion dollars. Including other expenses, the total average cost per Space Shuttle flight is about $1.5 billion USD. Clearly, this makes activities in space expensive.
