Unfavorable high-altitude winds force officials to halt the countdown to launch the SpaceX Falcon 9 rocket with the Deep Space Climate Observatory on Feb. 10.
Depending on how you count it, SpaceX launched its 100th kerosene-fueled Merlin 1D rocket engine on a Falcon 9 rocket Feb. 11, underscoring what it says is an accelerated flight regime for the centerpiece of the company’s propulsion shop.
SpaceX’s Falcon 9 rocket took off from Cape Canaveral on its 15th flight just before sunset Wednesday, putting on a spectacular sky show en route to space with a NOAA satellite to measure the solar wind.
