Scientists study ‘Death Star’ to save Earth

Computerized modeling of Mars’ moon Phobos has a connection with keeping the Earth safe from asteroids, the Lawrence Livermore National Laboratory (LLNL) announced on Wednesday. Phobos has a huge crater, more than five miles across, and a new computer model out of the LLNL in California simulates the dramatic impact that could have caused that distinctive crater. The research is part of a planetary defence program at LLNL— in other words, studying how to protect Earth from a devastating impact.
