Superconducting nanowire single-photon detectors (SNSPDs) are a promising new ultra-sensitive and low-noise detectors for applications ranging from deep-space exploration to ultrafast space-based optical quantum communication networks. Their susceptibility to damage from the high-radiation environments found in space is not yet understood. Professor Berggren and his team will investigate radiation damage to SNSPDs in their lab by bombarding them 30keV helium ions at irradiated doses far exceeding the expected levels in space. Using the results of these experiments and complementary modeling efforts the team will also investigate mitigation strategies.

      Aurora and airglow are seen from the International Space Station in 2015.Credits: NASA/JSC/ESRS NASA has selected three proposals for concept studies of missions to investigate the complex system of space weather that surrounds our planet and how it’s connected to Earth’s atmosphere.
      The three concepts propose how to enact the DYNAMIC (Dynamical Neutral Atmosphere-Ionosphere Coupling) mission, which was recommended by the 2013 Decadal Survey for Solar and Space Physics. The DYNAMIC mission is designed to study how changes in Earth’s lower atmosphere influence our planet’s upper atmosphere, where space weather like auroras and satellite disruptions are manifested. This knowledge will benefit humanity by helping us understand how space weather can interfere with crucial technology like navigation systems and satellites.
      “Earth and space are an interconnected system that reaches from the heart of our solar system, the Sun, to the lowest reaches of the atmosphere where we live and extends to the edge of our heliosphere – the boundary of interstellar space,” said Nicola Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “While space weather can spark the beautiful auroras across our skies, it also has the potential to cause disruptions for us here on Earth and can be dangerous for our spacecraft and astronauts in space. The DYNAMIC mission will expand our understanding of how Earth itself shapes space weather events that influence our home planet.”
      The DYNAMIC mission is designed to make measurements within Earth’s upper atmosphere between about 50-125 miles (80-200 kilometers) in altitude. With multiple spacecraft, DYNAMIC’s simultaneous observations from different locations can give scientists a more complete picture of how waves propagate upwards through this part of the atmosphere.
      NASA’s fiscal year 2023 appropriation directed NASA to initiate this first phase of study. As the first step of a two-step selection process, each proposal will receive $2 million for a concept study. NASA solicited missions with a cost cap of $250 million, which does not include the launch. The studies will last nine months.
      The selected concept teams are:
      University of Colorado, Boulder, led by principal investigator Tomoko Matsuo Key partners include Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland; NASA’s Jet Propulsion Laboratory in Southern California; and Massachusetts Institute of Technology’s Haystack Observatory in Westford, Massachusetts.
      University of Colorado, Boulder, led by principal investigator Aimee Merkel Key partners include BAE Systems in Westminster, Colorado, and the Naval Research Laboratory in Washington.
      Virginia Polytechnic Institute and State University, led by principal investigator Scott Bailey Key partners include Southwest Research Institute in San Antonio, Texas, Space Dynamics Laboratory in Logan, Utah, Global Atmospheric Technologies and Sciences in Newport News, Virginia, and Computational Physics, Inc. in Boulder, Colorado.

      Satellites continuously peer down from orbit to take measurements of Earth, and this week a group of scientists set sail to verify some of those data points.
      On June 2, the SCOAPE (Satellite Coastal and Oceanic Atmospheric Pollution Experiment) research team, in partnership with the U.S. Interior Department’s Bureau of Ocean Energy Management, took to the seas in the Gulf of Mexico for its second campaign to make surface-based measurements of air pollutants.
      The NASA/GSFC SCOAPE team launches an ozonesonde weather balloon from the stern of the research vessel Point Sur during the May 2019 cruise. Ryan Stauffer (NASA/GSFC) The primary pollutant scientists are measuring is nitrogen dioxide (NO2), the compound that reacts with sunlight to make ground-level ozone, said Anne Thompson, senior scientist emeritus for atmospheric chemistry at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and senior researcher at the University of Maryland, Baltimore County.
      The Gulf of Mexico is highly concentrated with oil and natural gas drilling platforms, which are sources of NO2. By taking measurements of these emissions from the sea surface nearby, scientists can help validate measurements taken from a much different vantage point. The research vessel the scientists are using, Point Sur, is owned by the University of Southern Mississippi and operated by the Louisiana Universities Marine Consortium.
      The Petronius deepwater oil platform flaring during the May 2019 SCOAPE cruise. The helicopter in the foreground is used as a means of transporting personnel to and from the platform. Ryan Stauffer (NASA/GSFC) “We’re the eyes on the surface to understand how well the eyes in the sky are working,” said Ryan Stauffer, research scientist for the atmospheric chemistry and dynamics laboratory at Goddard. Stauffer is also the principal investigator for the SCOAPE II project.
      For the first iteration of the project in 2019, ship-based measurements were compared to data gathered by the Ozone Monitoring Instrument aboard NASA’s Aura satellite and the Tropospheric Monitoring Instrument aboard ESA’s (European Space Agency) Sentinel-5 Precursor satellite. Both instruments fly on polar orbiting satellites, which pass over every part of the globe once per day. They capture snapshots at the same time each day, but cannot capture the short-lived NO2 emissions that come and go at different times.
      In 2024, the research team is working to validate the measurements taken by TEMPO (the Tropospheric Emissions: Monitoring of Pollution instrument), which was launched on a commercial satellite in April 2023. The TEMPO instrument provides a different perspective to the NO2 measurements due to its geostationary orbit — it focuses solely on North America and has a constant view of the Gulf of Mexico region. This allows scientists to better quantify emissions and make comparisons across all daylight hours.
      From space, satellites collect measurements of the “total column” of air, which means they measure the concentrations of NO2 from the land or ocean surface all the way up to the top of the atmosphere. With SCOAPE, scientists are taking measurements from the ship, about 33 feet above sea level, to focus measurements on the air that people breathe.
      The SCOAPE Pandora spectrometer instrument, which were used to gather the air quality near the operation sites, during sunset with a shallow water gas platform on the horizon.Ryan Stauffer (NASA/GSFC) Learning more about how those surface measurements compare to what satellites see in the total column can help scientists figure out how to use satellite data most effectively. Measuring NO2 from space over the past two decades has helped scientists understand how the compound affects air quality, and has helped to inform policies to reduce emissions of the pollutant.
      During SCOAPE’s 2019 campaign, researchers detected concentrations of methane – a significant greenhouse gas – near the Gulf Coast. This time around, the scientists are  looking to accurately measure these concentrations from the surface as well. They will mount the NASA Airborne Visible and InfraRed Imaging Spectrometer–3 imaging spectrometer instrument on a Dynamic Aviation B-200 plane to collect methane measurements above the Gulf, which will add an extra layer to understanding emissions of this potent greenhouse gas from Gulf of Mexico oil and gas operations.
      It has historically been difficult to measure methane from space, but scientists are working to build those capabilities. As with NO2, taking surface measurements helps scientists better understand the measurements taken from space.

      Rocket Lab’s Electron rocket lifted off from Launch Complex 1 at Māhia, New Zealand at 11:15 p.m. NZST June 5, 2024, carrying a small satellite for NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission. RocketLab The second of NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) two satellites is communicating with ground controllers after launching at 3:15 p.m. NZST, Wednesday (11:15 p.m. EDT, June 4). Data from these two shoebox-size cube satellites, or CubeSats, will better predict how Earth’s ice, seas, and weather will change in a warming world — providing information to help humanity thrive on our changing planet.  
      The CubeSat launched on top Rocket Lab’s Electron rocket from the company’s Launch Complex 1 in Māhia, New Zealand, and follows the May 25 launch of the first PREFIRE CubeSat. After a 30-day checkout period, when engineers and scientists confirm both CubeSats are operating normally, the mission is expected to operate for 10 months.
      “By helping to clarify the role that Earth’s polar regions play in regulating our planet’s energy budget, the PREFIRE mission will ultimately help improve climate and ice models,” said Amanda Whitehurst, PREFIRE program executive, at NASA Headquarters in Washington. “Improved models will benefit humanity by giving us a better idea of how our climate and weather patterns will change in the coming years.”
      Capitalizing on NASA’s unique vantage point in space, PREFIRE will help understand the balance between incoming heat energy from the Sun and the outgoing heat given off at Earth’s poles. The Arctic and Antarctica act something like the radiator in a car’s engine shedding much of the heat initially absorbed at the tropics back into space. The majority of that heat is emitted as far-infrared radiation. The water vapor content of the atmosphere, along with the presence, structure, and composition of clouds, influences the amount of radiation that escapes into space from the poles.
      The PREFIRE mission will give researchers information on where and when far-infrared energy radiates from the Arctic and Antarctic environments into space. The mission also will use its two CubeSats in asynchronous, near-polar orbits to study how relatively short-lived phenomena like cloud formation, moisture changes, and ice sheet melt affect far-infrared emissions over time. The two satellites pass over the same part of Earth at different times of day, giving researchers information on changing conditions.
      “Climate change is reshaping our environment and atmosphere in ways that we need to prepare for,” said Brian Drouin, PREFIRE’s deputy principal investigator at NASA’s Jet Propulsion Laboratory in Southern California. “This mission will give us new measurements of the far-infrared wavelengths being emitted from Earth’s poles, which we can use to improve climate and weather models and help people around the world deal with the consequences of climate change.”
      Each CubeSat carries an instrument called a thermal infrared spectrometer, which uses specially shaped mirrors and sensors to measure infrared wavelengths. Miniaturizing the instruments to fit on CubeSats required downsizing some parts while scaling up other components.
      “Equipped with advanced infrared sensors that are more sensitive than any similar instrument, the PREFIRE CubeSats will help us better understand Earth’s polar regions and improve our climate models,” said Laurie Leshin, director at NASA JPL. “Their observations will lead to more accurate predictions about sea level rise, weather patterns, and changes in snow and ice cover, which will help us navigate the challenges of a warming world.”
      NASA’s Launch Services Program, based out of the agency’s Kennedy Space Center in Florida, in partnership with NASA’s Earth System Science Pathfinder Program, is providing the launch service as part of the agency’s Venture-class Acquisition of Dedicated and Rideshare (VADR) launch services contract.
      The PREFIRE mission was jointly developed by NASA and the University of Wisconsin-Madison. NASA JPL manages the mission for the agency’s Science Mission Directorate and provided the spectrometers. Blue Canyon Technologies built the CubeSats and the University of Wisconsin-Madison will process the data the instruments collect. The launch services provider is Rocket Lab USA Inc. of Long Beach, California.

      It’s not just rising air and water temperatures influencing the decades-long decline of Arctic sea ice. Clouds, aerosols, even the bumps and dips on the ice itself can play a role. To explore how these factors interact and impact sea ice melting, NASA is flying two aircraft equipped with scientific instruments over the Arctic Ocean north of Greenland this summer. The first flights of the field campaign, called ARCSIX (Arctic Radiation Cloud Aerosol Surface Interaction Experiment), successfully began taking measurements on May 28.
      Two NASA aircraft are taking coordinated measurements of clouds, aerosols and sea ice in the Arctic this summer as part of the ARCSIX field campaign. In this image from Thursday, May 30, NASA’s P-3 aircraft takes off from Pituffik Space Base in northwest Greenland behind the agency’s Gulfstream III aircraft.Credit: NASA/Dan Chirica “The ARCSIX mission aims to measure the evolution of the sea ice pack over the course of an entire summer,” said Patrick Taylor, deputy science lead with the campaign from NASA’s Langley Research Center in Hampton, Virginia. “There are many different factors that influence the sea ice. We’re measuring them to determine which were most important to melting ice this summer.”
      On a completely clear day over smooth sea ice, most sunlight would reflect back into the atmosphere, which is one way that sea ice cools the planet. But when the ice has ridges or darker melt ponds — or is dotted with pollutants — it can change the equation, increasing the amount of ice melt. In the atmosphere, cloudy conditions and drifting aerosols also impact the rate of melt.
      “An important goal of ARCSIX is to better understand the surface radiation budget — the energy interacting with the ice and the atmosphere,” said Rachel Tilling, a campaign scientist from NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
      About 75 scientists, instrument operators, and flight crew are participating in ARCSIX’s two segments based out of Pituffik Space Base in northwest Greenland. The first three-week deployment, in May and June of this year, is timed to document the start of the ice melt season. The second deployment will occur in July and August to monitor late summer conditions and the start of the freeze-up period.
      “Scientists from three key disciplines came together for ARCSIX: sea ice surface researchers, aerosol researchers, and cloud researchers,” Tilling said. “Each of us has been working to understand the radiation budget in our specific area, but we’ve brought all three areas together for this campaign.”
      Two aircraft will fly over the Arctic during each deployment. NASA’s P-3 Orion aircraft from the agency’s Wallops Flight Facility in Virginia, will fly below the clouds at times to document the surface properties of the ice and the amount of energy radiating off it. The team will also fly the aircraft through the clouds to sample aerosol particles, cloud optical properties, chemistry, and other atmospheric components.
      A Gulfstream III aircraft, managed by NASA Langley, will fly higher in the atmosphere to observe properties of the tops of the clouds, take profiles of the atmosphere above the ice, and add a perspective similar to that of orbiting satellites.
      The teams will also compare airborne data with satellite data. Satellite instruments like the Multi-angle Imaging Spectroradiometer and the Moderate Resolution Imaging Spectroradiometer will provide additional information about clouds and aerosol particles, while the Ice, Cloud, and land Elevation Satellite 2 will provide insights into the ice topography below both satellites and aircraft.
      The aircraft will fly coordinated routes to take measurements of the atmosphere above ice in three-dimensional space, said Sebastian Schmidt, the mission’s science lead with the University of Colorado Boulder.
      “The area off the northern coast of Greenland can be considered the last bastion of multi-year sea ice, as the Arctic transitions to a seasonally ice-free ocean,” Schmidt said. “By observing here, we will gain insight into cloud-aerosol-sea ice-interaction processes of the ‘old’ and ‘new’ Arctic — all while improving satellite-based remote sensing by comparing what we’re seeing with the airborne and satellite instruments.”
