A powerful storm the National Weather Service says is "of historic proportions" stranded hundreds of people and left thousands without power Wednesday night after it intensified into a raging blizzard across the Plains. It brought with it hurricane-force wind gusts, widespread flooding and white-out conditions to multiple states from Colorado to the Dakotas.
Why it matters: This storm's strength and rate of intensification is unusual for the Plains states, with low pressure records likely to be challenged or broken in multiple locations. In general, the lower the air pressure, the stronger the storm.
NASA administrator Jim Bridenstine told members of the Senate Commerce, Science and Transportation Committee on Wednesday that NASA is considering launching the first mission of its Orion crew capsule in 2020 using commercial rockets rather than the agency's Space Launch System (SLS). The mission, which won't carry crew, will test the capsule in deep space during its three weeks around the moon.
Why it matters: The admission that the long-delayed SLS may not be ready in time to launch the first Orion mission in 2020 comes in the wake of development delays and cost overruns of what would be NASA's most powerful rocket ever developed. It also delivers a blow to Boeing, which is one of the main contractors for the SLS, and a potential boost to another private sector launch company, like United Launch Alliance or Elon Musk's SpaceX.
