WALLOPS ISLAND, Va. – It is pretty to look at, but at times, treacherous to encounter: when snowstorms wreak havoc on the ground, it can come with a cost. Yet, because of limited research, snowstorms are not as well-understood as other weather phenomenon. That’s about to change. Inside a noisy hangar at NASA’s Wallops Island facility in Virginia sits a specially outfitted P-3 aircraft, also known as a “snow chaser.” “Snow can have a huge economic impact,” said Lynn McMurdie, principal investigator for a new research project called IMPACTS. “To be able to fly inside the clouds, where the snowflakes form, enables us to study the processes that go into forming the snowflakes that eventually fall down to the earth as snowfall in your backyard.” It’s all part of a five-year, million research project called IMPACTS, which stands for Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms. The team is embarking on its first snowstorm chasing flights this month. “It gets a bit turbulent. The plane is very capable and has great de-icing systems,” said Gerrit Everson, chief of flight operations at Wallops Flight Facility and a NASA pilot. “We would never put our crew or our passengers or the scientists in an unsafe position. So, we do a very good job at mitigating the risk. But, yeah, you do have to be willing to accept a certain degree of turbulence and bumps here and there.” It’s been 30 years since there’s been a major study of snowstorms like this one. What researchers are hoping to find out this time around isn’t just where the snow is going to fall, but how intense that snowfall might be. “People think the forecasting is really easy and simple, but it's actually very complicated,” McMurdie said. “Hopefully, we will be doing a better job so we can help joe citizen know what to do when there is a storm threatening.” Beyond that, scientists hope to also learn how snowfall can impact the water supply all over the planet. “We need water to survive and we need to understand how the water goes through the whole earth system,” McMurdie said.It’s a global ecosystem where winter wonderlands play a crucial part. 2186

The coveted crash test ratings for vehicles are in desperate need of an update, according to multiple auto safety groups. The system hasn't been updated since 2010. Right now, 98% of all vehicles get four or five stars. “It’s the equivalent of Halloween — everyone gets candy,” says Jason Levine with the Center for Auto Safety. “The idea is supposed to be separating between things that are safe and things that are really safe.” Levine says the tests are too easy to pass and they don't help consumers understand the difference between cars.Some recommendations include updating the ratings by testing new technology that helps drivers avoid crashes, like emergency automatic braking, and accounting for how passengers in the rear seats are impacted Experts also recommend testing systems that help avoid hitting pedestrians. This type of testing already exists, it just hasn't been mandated in the U.S. “NHSTA, the National Highway Traffic Safety Administration, has dragged its feet on renewing these ratings for almost a decade now,” Levine says. “They said they were going to update them in 2015. They didn't. They said they were going to update them in 2018 and they didn't. Here we are, we just saw a press release of NHSTA saying we'll do something in 2020 but they haven't even really explained what that is.” Advocates also say there's a need to update crash test dummies to reflect changes we've seen in drivers, like weight, height and age.Auto safety groups would like to see a silver star added for older drivers to better understand how a car might protect them in a crash. 1604
