NASA has selected the University of New Hampshire in Durham to build Solar Wind Plasma Sensors for the Lagrange 1 Series project, part of the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Next Program.
This cost-plus-no-fee contract is valued at approximately $24.3 million and includes the development of two sensors that will study the Sun’s constant outflow of solar wind. The data collected will support the nation’s efforts to better understand space weather around Earth and to provide warnings about impacts such as radio and GPS interruptions from solar storms.
The overall period of performance for this contract will be from Thursday, Oct. 24, and continue for a total of approximately nine years, concluding 15 months after the launch of the second instrument. The work will take place at the university’s facility in Durham, New Hampshire, and at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. Johns Hopkins is the significant subcontractor.
Under this contract, the University of New Hampshire will be required to design, analyze, develop, fabricate, integrate, test, verify, and evaluate the sensors, support their launch, supply and maintain the instrument ground support equipment, and support post-launch mission operations at the NOAA Satellite Operations Facility in Suitland, Maryland.
The Solar Wind Plasma Sensors will measure solar wind, a supersonic flow of hot plasma from the Sun, and provide data to NOAA’s Space Weather Prediction Center, which issues forecasts, warnings and alerts that help mitigate space weather impacts. The measurements will be used to characterize coronal mass ejections, corotating interaction regions, interplanetary shocks and high-speed flows associated with coronal holes. The measurements will also include observing the bulk ion velocity, ion temperature and density and derived dynamic pressure.
NASA and NOAA oversee the development, launch, testing, and operation of all the satellites in the L1 Series project. NOAA is the program owner that provides funds and manages the program, operations, and data products and dissemination to users. NASA and commercial partners develop, build, and launch the instruments and spacecraft on behalf of NOAA.

A timelapse of the Twin Rockets to Investigate Cusp Electrodynamics (TRICE-2) mission launching from Andøya Space Center in Andenes, Norway on Dec. 8, 2018. NASA/Jamie Adkins When it comes to discoveries about our upper atmosphere, it pays to know your surroundings.
Using data from the Twin Rockets to Investigate Cusp Electrodynamics (TRICE-2) rocket launch, NASA scientist Francesca Di Mare and Gregory Howes from the University of Iowa studied waves traveling down Earth’s magnetic field lines into the polar atmosphere. These waves were known to accelerate electrons, which pick up speed as they “surf” along the electric field of the wave. But their effect on ions — a more heterogenous group of positively charged particles, which exist alongside electrons — was unknown.
By estimating the ion mixture they were flying through — predominantly protons and singly-charged oxygen ions — the scientists discovered that these waves were accelerating protons as they circle about the Earth’s magnetic field lines as well as electrons as they surf the waves. The findings reveal a new way our upper atmosphere is energized.

NASA Mission to Study Mysteries in the Origin of Solar Radio Waves
NASA’s CubeSat Radio Interferometry Experiment, or CURIE, is scheduled to launch July 9, 2024, to investigate the unresolved origins of radio waves coming from the Sun.
CURIE will investigate where solar radio waves originate in coronal mass ejections, like this one seen in 304- and 171-angstrom wavelengths by NASA’s Solar Dynamics Observatory. NASA/Goddard Space Flight Center Scientists first noticed these radio waves decades ago, and over the years they’ve determined the radio waves come from solar flares and giant eruptions on the Sun called coronal mass ejections, or CMEs, which are a key driver of space weather that can impact satellite communications and technology at Earth. But no one knows where the radio waves originate within a CME.
The CURIE mission aims to advance our understanding using a technique called low frequency radio interferometry, which has never been used in space before. This technique relies on CURIE’s two independent spacecraft — together no bigger than a shoebox — that will orbit Earth about two miles apart. This separation allows CURIE’s instruments to measure tiny differences in the arrival time of radio waves, which enables them to determine exactly where the radio waves came from.
“This is a very ambitious and very exciting mission,” said Principal Investigator David Sundkvist, a researcher at the University of California, Berkeley. “This is the first time that someone is ever flying a radio interferometer in space in a controlled way, and so it’s a pathfinder for radio astronomy in general.”
CURIE team members work on integrating the satellites into the CubeSat deployer. ExoLaunch The spacecraft, designed by a team from UC Berkeley, will measure radio waves ranging 0.1 to 19 megahertz to pinpoint the radio waves’ solar origin. These wavelengths are blocked by Earth’s upper atmosphere, so this research can only be done from space.
CURIE will launch aboard an ESA (European Space Agency) Ariane 6 rocket in early July from the Guiana Space Center in Kourou, French Guiana. The rocket will take CURIE to 360 miles above Earth’s surface, where it can get a clear view of the Sun’s radio waves.
Once in its circular orbit, the two adjoined CURIE spacecraft will establish communication with ground stations before orienting and separating. When the separated satellites are in formation, their dual eight-foot antennas will deploy and start collecting data.
CURIE is sponsored by NASA’s Heliophysics Flight Opportunities for Research and Technology (H-FORT) Program and is the sole mission manifested on the NASA CubeSat Launch Initiative’s ELaNa (Educational Launch of Nanosatellites) 43 mission. As a pathfinder, CURIE will demonstrate a proof-of-concept for space-based radio interferometry in the CubeSat form factor. CURIE will also pave the way for the upcoming Sun Radio Interferometer Space Experiment, or SunRISE, mission. SunRISE will employ six CubeSats to map the region where the solar radio waves originate in 2-D.

Dennis Gallagher (ST13) reports receiving on 3/1/24, one gram of Apollo 16 regolith of 1 mm and smaller dust regolith from the Johnson Space Center (JSC) Apollo Archive. The material request is motivated by the planned NASA Artemis missions to the Moon’s south polar region where the surface is generally expected to be like that found at the Apollo 16 landing site. Electrostatic charging driven by the solar wind and ultraviolet light from the Sun is known to be important for small particles of lunar regolith that must be understood for potentially dust coated struts of the Human Lander System (HLS) that will cycle between the surface and Gateway. Presently, the charging properties of individual dust grains are not adequately characterized for this purpose. The measurements to be obtained by the MSFC Dusty Plasma Laboratory using Apollo 16 dust are intended to fill this knowledge gap are being obtained in support of the Gateway Cis-Lunar Dust Transfer Modeling and Analysis Task and HLS at JSC.
