Following the conclusion of its investigation into an explosion last year in September, Elon Musk's Space Exploration Technology Corp., or SpaceX, will take its rocket to the launch pad again on Sunday,
About eight minutes before a test launch of its Falcon 9, the company says, an unexpected collection of oxygen in the helium tanks' aluminum lining ignited an explosion--which also destroyed a commercial satellite owned by Iridium Communications Inc. This follows a 2015 incident involving a Falcon 9 en route to deliver cargo to the international space station. A rupture in the vehicle caused it to break down shortly after launching.
Upon reviewing SpaceX's findings, the Federal Aviation Administration (FAA) must issue authorization and a license for the relaunch. For now, SpaceX has tweaked its fueling method in hopes of avoiding another disaster ahead of Sunday's launch from California's Vandenberg Air Force Base.
