WebSpace debris is human-made and comes from objects that people launched into Earth orbit. It is usually moving parallel to the ground, at a speed of about 7 km/sec or 17,500 miles per hour. The reentry can occur at any time of the day. WebMaterial 1 melts at approx. 140°C, material 2 at 230°C – with 200 W laser power, one can therefore cut material 1 faster than material 2, as the energy doesn't have to be applied for as long to material 1 as to material 2. Consequently it can be said that a laser beam itself has no temperature. Do you have any questions?
