the perfect material that we will use to make the spacecraft is the aluminium. Because it's a conductor of electricity, it's non-magnetic, it's not heavy or too light, and it bounces very little

# data[].attributes.body
we want a material that will be able to absorb all the necessary impacts without hurt the spacecraft.

we are searching for a material that is not too heavy but also not too light.

Spacecraft such as satellites can be hit by space debris travelling at very high speeds. We need to use tough materials which canresist such impacts. You are going to use a special ramp to measure the rebound after a marble impacts each test material. The more the rebound, the less the damage to the material.

To create a spacercraft with the correct materials we have to be careful with a serie of properties.

It takes a lot of roket fuel to launch a spacecraft into space and this is also very expensive. We need materials which are strong, stiff, and have a low mass (light in weight) to build spacecraft.

# data[].attributes.body
When moving in space, it can be helpful if the material making up the spacecraft is non-magnetic. Materials in spacecraft which are magnteic need to be avoided because they can disturb instruments suh as the onboard orientation device, which uses the Earth's magnetic field to point the spacecraft in the right direction.

# data[].attributes.body
The materials to be used arround the electrical components of the spacecraft needs to be a good electrical conductor, so that it can conduct away elctrical charge, wich could otherwise damage the components
