How this Martian moon became the 'Death Star'
Mars’ largest moon, Phobos, has captured public imagination and been shrouded in mystery for decades. But numerical simulations recently conducted at Lawrence Livermore National Laboratory (LLNL) have shed some light on the enigmatic satellite. The dominant feature on the surface of Phobos (22-kilomters across) is Stickney crater (9-km across), a mega crater that spans…
Underwater survival story presents physics puzzle
When Lawrence Livermore National Laboratory physicist Maxim Umansky flipped through the news, a startling underwater survival story caught his attention. In May, a boat cook survived a 60-hour underwater ordeal 100 feet below the surface after his tugboat sank near the Nigerian coast.Harrison Okene's survival underwater while the rest of the crew perished was astounding…
