Not every part of a satellite burns up in reentry. Considering the growing number of satellites in orbital space, that's a big problem.
- Earth's orbital space is getting more crowded by the day.
- The more satellites and space junk we put into orbit, the greater a risk that there could be a collision.
- Not all materials burn up during reentry; that's why scientists need to stress test satellite parts to ensure that they won't become deadly falling objects.
When it comes to climate change, today's airplane pollution is a real problem.
- A new partnership between the Delft University of Technology and KLM Royal Dutch Airlines has been announced along with a plan for a striking new plane.
