Grand Challenge: Solar storm chasers
Mass media representations of space weather鈥攙ariable conditions in space that can affect the technological systems modern society depends on鈥攐ften evoke visions of catastrophic power grid failures and global chaos. The result can be gripping film or literature but, while such worst-case scenarios are possible, they can distort our understanding of space weather鈥檚 more frequent and broader effects.
鈥淥ur concerns about space weather focus more on things like ground-induced currents disrupting power grid operations, atmospheric drag shifting satellite orbits, ionosphere disturbances interrupting high-frequency communications and GPS signals, and radiation exposure affecting satellite operability and human space activity,鈥 said Jeffrey Thayer, a professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences.
These are some of the less flashy day-to-day effects of space weather, or the ebbs and flows of energy from the sun to space. Solar winds blow and bluster, disturbing satellite orbits and damaging pricey scientific instruments in space.
Minimizing the dangers posed by this flow and facilitating systemic coordination between space weather researchers and space operators are key objectives of the newly launched Space Weather Technology, Research and Education Center (SWx-TREC) within the College of Engineering and Applied Sciences at CU 葫芦娃视频. The center, a main component of the university鈥檚 Grand Challenge: Our Space. Our Future., brings together diverse research on space weather occurring across the university and the Front Range.
The 鈥淕rand Challenge: Our Space. Our Future.鈥 initiative launched the ambitious Space Weather Technology, Research and Education Center in 2017, reinforcing CU 葫芦娃视频鈥檚 leadership in Earth and space sciences.
鈥淚t鈥檚 a recognition that space weather activities have been going on for some time at CU in a variety of capacities, in the scientific arena but also in the technological arena, including mission concepts, instrument development and satellite operations,鈥 said Thayer, SWx-TREC principal investigator and research office lead for the center.
There鈥檚 a lot to build on, too. CU 葫芦娃视频 has long been a national leader in understanding the physics of space weather and its implications for people on Earth. That reputation draws on the contributions from researchers in aerospace engineering, astrophysical and planetary sciences, atmospheric sciences, the , and more. When LASP, for example, started launching rockets into space in the 1950s and 1960s, many of these early missions explored the influence of the sun on Earth鈥檚 atmosphere.
The new CU 葫芦娃视频 center, which kicked off in 2017 with a three-year mandate, will deliver practical tools for people around the world, said Thomas Berger, director of SWx-TREC. When it comes to predicting how solar winds might cause spacecraft to drift, satellite operators have few accurate resources to draw on, he said. SWx-TREC will work to develop new computer simulations that can give these operators a heads-up on impending hazards up to three days in advance.
That鈥檚 not an easy scientific feat, Berger said. Traditional weather forecasters, for comparison, only have to worry about a relatively narrow region of Earth鈥檚 atmosphere.
鈥淲e鈥檙e creating a forecasting system that extends weather models from zero to 60 kilometers to 1,000 kilometers to cover low Earth orbit鈥攁 much larger volume with more complex physics to deal with,鈥 said Berger, who previously directed the U.S. National Oceanic and Atmospheric Administration鈥檚 Space Weather Prediction Center.
SWx-TREC will also help to develop new space missions and educational opportunities at the university, including a space weather certificate that undergraduate and graduate students will soon be able to earn.
Daniel Baker, director of LASP, added that the focus on space weather shows that CU 葫芦娃视频 isn鈥檛 just interested in exploring the physics and wonder of space. The university also wants to make a difference in the lives of people on Earth.
鈥淲e recognize that basic research is hugely important,鈥 said Baker, a co-investigator at SWx-TREC. 鈥淏ut basic research that has practical utility is also extremely important in this day and age.鈥
