THE NEW SPACE RACE: SpaceX delays Polaris Dawn astronaut launch until at least Aug. 30 due to bad weather. “Polaris Dawn was originally scheduled to launch early Monday morning (Aug. 26) from NASA’s Kennedy Space Center in Florida, but SpaceX pushed things back a day to perform more preflight checkouts. The company then called the planned Tuesday (Aug. 27) attempt off after detecting a helium leak, targeting Wednesday (Aug. 28) instead. But now Mother Nature has foiled that plan.”
