A 518-million-year-old ambulacrarian fossil from China suggests that the common ancestor of starfish and their relatives was not a burrowing worm; it was probably a tentacled animal that fed from the water around it.
On Thursday evening, Blue Origin attempted to test fire its massive New Glenn rocket at its Florida launch site, but something went very wrong after engine ignition. The super heavy lift rocket exploded in spectacular and disastrous fashion.
The static fire test was being filmed by NASASpaceflight.com on its Space Coast Live feed, which captured video of the conflagration that followed the destruction of the booster. The first stage of New Glenn, fueled with methane, produced a massive fireball above the launch site along the Florida coast, LC-36A. It is possibly the most dramatic and powerful rocket explosion since the Soviet Union's N1 rocket was destroyed during a launch attempt in 1969.
