It is a real problem, and we are going to have some catastrophic consequences if we cannot get nations that are launching things into space to provide enough fuel to have a controlled reentry.

NASA is committed to building a diverse, skilled future STEM workforce--our next generation of explorers with the technical skills needed to carry forward our Nation's vital mission.

What we are going to do is a multi-year test, taking it to different locations all over the United States, and see if the muffled roar is acceptable to the people on the ground.

All of us have a responsibility to protect our home planet. After all, it's the only one we have.
