NASA experts, and other space agencies who spend vast amounts of money sending space crafts millions of miles through space to other planets, should consider saving some of that money to protect the world from asteroid collisions.
Many experts fear it is only a matter of time before a huge asteroid threatens to hit the Earth.
Earth is hit by a large asteroid every 100,000 years, and the next one is overdue.
