Radio JOVE Volunteers Tune In to the Sun’s Low Notes
As the Sun approaches the most active part of its eleven-year magnetic cycle this summer, NASA volunteers have been watching it closely. Now they’ve spotted a new trend in solar behavior that will have you reaching for your suntan lotion. It’s all about something called a “Type II” solar radio burst:
“Type II solar radio bursts are not commonly detected in the frequency range between 15 to 30 megahertz,” said Prof. Chuck Higgins, Co-founder of Radio JOVE. “Recently, we’re seeing many of them in that range.”
Let’s unpack that. Our Sun often sprays powerful blasts of radio waves into space. Heliophysicists classify these radio bursts into five different types depending on how the frequency of the radio waves drifts over time. “Type II” solar radio bursts seem to come from solar flares and enormous squirts of hot plasma called coronal mass ejections.
Now, Thomas Freeman, an undergraduate student at Middle Tennessee State University, and other volunteers working on NASA’s Radio JOVE project have observed something interesting about these Type II bursts: they are now showing up at lower frequencies—somewhere in between FM and AM radio.
What does it mean? It means our star is full of surprises! These Radio JOVE observations of the Sun’s radio emissions during solar maximum can be used to extend our knowledge of solar emissions to lower frequencies and, therefore, to distances farther from the Sun.
Radio JOVE is a NASA partner citizen science project in which participants assemble and operate radio astronomy telescopes to gather and contribute data to support scientific studies. Radio JOVE collaborated with SunRISE Ground Radio Lab, organized teams of high school students to observe the Sun, and recently published a paper on these Type II solar radio bursts.

The Milky Way brightens the moonless summer sky this week: Here's where to look
NASA Seeks Industry Concepts on Moon, Mars Communications
NASA is seeking proposals from U.S. companies about innovative Moon and Mars proximity relay communication and navigation capabilities as the agency aims to use private industry satellite communications services for emerging missions.
On July 7, NASA issued a Request for Proposals, soliciting advanced industry concepts to establish high-bandwidth, high-reliability communications infrastructure between the lunar surface and an Earth-based operations control center, along with concepts that establish a critical communications relay on the Martian surface and transfer data between Mars and the Earth.
“These partnerships foster important advancements in communications and navigation,” said Greg Heckler, deputy program manager for capability development within NASA’s SCaN (Space Communications and Navigation) Program. “It allows our astronauts, our rovers, our spacecraft – all NASA missions – to expand humanity’s exploration of the Moon, Mars, and beyond.”
NASA’s request directly supports the agency’s long-term vision of an interoperable space communication and navigation infrastructure that enables science, exploration, and economic development in space. NASA, as one of many customers, will establish a marketplace that supports cost-effective commercial services involving communication needs on and around the Moon and Mars.
Responses are due by 5 p.m. EDT, Wednesday, Aug. 13.
NASA’s SCaN Program serves as the management office for the agency’s space communications and navigation. More than 100 NASA and non-NASA missions rely on SCaN’s two networks, the Near Space Network and the Deep Space Network, to support astronauts aboard the International Space Station and future Artemis missions, monitor Earth’s weather, support lunar exploration, and uncover the solar system and beyond.

GRUVE Lab
The GRUVE (Glenn Reconfigurable User-Interface and Virtual Reality Exploration) Lab is located within the GVIS Lab. It is home to the CAVE, which is predominantly used for mission scenarios and to tour virtual environments of NASA facilities.
GRUVE Lab VisualizationUsers virtually explore a facility at NASA’s Glenn Research Center in Cleveland.NASA GRUVE Lab DemonstrationA user analyzes a visualization of a prototype structure.NASA GRUVE Lab VisualizationA user analyzes a visualization of a prototype structure that will be used for a fire experiment on the Moon.NASA GRUVE Lab VisualizationA Graphics and Visualization Lab (GVIS) intern in the Cave Automatic Virtual Environment (CAVE).NASA GRUVE Lab TourA user takes a virtual tour of a facility at NASA’s Glenn Research Center in Cleveland.NASA How GRUVE WorksGRUVE allows multiple people to view a visualization in 3D together. These visualizations include 3D models of NASA facilities and intricate images created from collected data.
Powerful projectors and mirrors, in combination with an infrared motion tracking system and active-shutter glasses, allow viewers to view 3D models and data in perfect perspective. 3D models effectively pop off the screen and remain proportional no matter where the user with the pair of tracking glasses moves in the environment.
The CAVE can be driven by either a Windows or Linux computer system, enabling the team to use the best environment for a given problem and software tool.
The CAVE setup immerses the user in 3D visualizations through walls on all sides, projectors from above, tracking cameras, and mirrors hidden behind the facade.Visbox, Inc. Benefits of GRUVE
The CAVE’s technology provides a unique advantage for researchers, scientists, engineers, and others. Seeing and analyzing forces and data that would otherwise not be viewable to the human eye allows the observer to understand their subject matter in more detail.
Benefits of GRUVE to research include:
- Providing an immersive environment: with large screens to fill peripheral vision and stereoscopic projection for a real sense of three-dimensional space, more parts of the brain are engaged, and the user is better able to understand problems and solve them faster
- More effective collaboration: the ability to see each other in the virtual reality environment makes GRUVE better for collaboration than traditional VR technology
- Seeing complex data and flows in 3D: this makes it easier for both experts and non-experts to understand the data
- Providing greater resolution and larger display size: this allows details to be displayed without losing their context
- Delivering faster and more accurate manipulation and viewing of models, including CAD data, with fewer errors: this results in a faster time to market and less re-work
All members of NASA Glenn may use GRUVE for their projects.

GVIS History
In 1982, a $20 million supercomputer was brought to NASA Glenn. Scientists at NASA Glenn were becoming increasingly reliant on computer simulations to test their experiments. Advancements in computer technology allowed a different type of testing environment — one that revolved around virtual models and data over physical observation. The benefits of this method included a decrease in costs, a decrease in associated risk, faster turnaround, and more data.

In short, there was simply too much data to be analyzed. To solve this problem, NASA Glenn built the Interactive Computer Aided Research Engineering system (ICARE) in the center’s Research Analysis Center.
Taking up several rooms, consisting of 22 total workstations, and costing a grand total of $20 million, the ICARE system was a way for scientists to examine their data through the aid of supercomputer visualizations. Using both graphical and modular methods, ICARE’s visualizations revealed and shared information in ways that traditional methods could not match.
The construction and implementation of the ICARE system was revolutionary to both the center and NASA as a whole. Before 1982, NASA already had an established interest in powerful computers; however, the ICARE system took NASA into the era of supercomputing. ICARE also brought increased attention to the value and power of scientific visualization.

NASA Glenn wanted the latest scientific visualization technology and techniques for its scientists, so the center expanded the Research Analysis Center to make room for the new Graphics and Visualization Lab (GVIS). The GVIS Lab acquired cutting-edge graphics technology, including studio-quality TV animation and recording equipment, stereographic displays, and image processing systems. Later, the High-Performance Computing Act of 1991 provided funding and opportunities to add high-speed computing, virtual reality, and collaborative visualization to its fleet of tools.

During this period, the GVIS Lab was responsible for assisting NASA Glenn scientists who needed help visualizing their data. The lab was also tasked with inventing new visualization techniques and promoting NASA Glenn’s activities though tours, videos, and other outreach programs. Some of the techniques the lab developed included particle tracking, iso-surface contours, and volume visualization. Tour guests included school children, corporate VIPs, local and national politicians, TV news media, and researchers from other national labs. Using state-of-the-art recording and editing hardware, the GVIS Lab regularly shared work both inside and outside of NASA.
As other labs and researchers began to gain access to their own scientific visualization tools, the GVIS Lab shifted its focus to experimenting with virtual reality- and augmented reality-based visualizations.

The team takes pride in pushing the limits of scientific visualization and computer science, helping fellow researchers make sense of their data, and inspiring the next generation through demonstrations and presentations. Computational technology has come a long way since the days of ICARE, but GVIS has continued to explore current and cutting-edge technologies.
In addition to scientific visualization and experimental computational technologies, the GVIS Lab now also specializes in virtual design, interactive 3D simulations, natural user interface development, applications of computer science, and mission scenario visualizations. The team uses the latest edition of 3D programs and VR devices to experiment with how these systems can be used to visualize data, pushing their input and output capabilities.
With all this technology, GVIS also supports the visualization of a wide variety of 3D data and models such as CAD, point clouds, and volume data. Additionally, the lab is capable of high-impact data visualization, web-based visualization, time-accurate data representation, and designing and testing CAD models in virtual reality.

USBR Seal Team Fix Challenge
When a reservoir conduit cannot be closed, thousands of cubic feet of water can roar through uncontrolled, threatening public safety, irreplaceable reservoir storage, and power generation. Seal Team Fix invites engineers, fabricators, and creative problem-solvers to stop that torrent in its tracks. Your mission: design a rapid-deploying, temporary seal that can be deployed to a submerged 3- to 25-ft diameter conduit opening, accommodate differential pressure, and achieve a 95–98 % flow reduction – without leaning on trash racks or other non-structural surfaces. The competition unfolds in three phases: a short-format concept white paper, a funded prototype build, and a lab-scale hydraulic demonstration.
Award: $575,000 in total prizes
Open Date: July 22, 2025
Close Date: October 14, 2025

NASA, JAXA XRISM Satellite X-rays Milky Way’s Sulfur
4 min read
NASA, JAXA XRISM Satellite X-rays Milky Way’s SulfurAn international team of scientists have provided an unprecedented tally of elemental sulfur spread between the stars using data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) spacecraft.
Astronomers used X-rays from two binary star systems to detect sulfur in the interstellar medium, the gas and dust found in the space between stars. It’s the first direct measurement of both sulfur’s gas and solid phases, a unique capability of X-ray spectroscopy, XRISM’s (pronounced “crism”) primary method of studying the cosmos.
“Sulfur is important for how cells function in our bodies here on Earth, but we still have a lot of questions about where it’s found out in the universe,” said Lía Corrales, an assistant professor of astronomy at the University of Michigan in Ann Arbor. “Sulfur can easily change from a gas to a solid and back again. The XRISM spacecraft provides the resolution and sensitivity we need to find it in both forms and learn more about where it might be hiding.”
A paper about these results, led by Corrales, published June 27 in the Publications of the Astronomical Society of Japan.

Using ultraviolet light, researchers have found gaseous sulfur in the space between stars. In denser parts of the interstellar medium, such as the molecular clouds where stars and planets are born, this form of sulfur quickly disappears.
Scientists assume the sulfur condenses into a solid, either by combining with ice or mixing with other elements.
When a doctor performs an X-ray here on Earth, they place the patient between an X-ray source and a detector. Bone and tissue absorb different amounts of the light as it travels through the patient’s body, creating contrast in the detector.
To study sulfur, Corrales and her team did something similar.
They picked a portion of the interstellar medium with the right density — not so thin that all the X-rays would pass through unchanged, but also not so dense that they would all be absorbed.
Then the team selected a bright X-ray source behind that section of the medium, a binary star system called GX 340+0 located over 35,000 light-years away in the southern constellation Scorpius.

The composite contains a blend of imagery in X-rays (represented in deep blue), infrared, and optical light.DSS/DECaPS/eRosita/NASA’s Goddard Space Flight CenterUsing the Resolve instrument on XRISM, the scientists were able to measure the energy of GX 340+0’s X-rays and determined that sulfur was present not only as a gas, but also as a solid, possibly mixed with iron.
“Chemistry in environments like the interstellar medium is very different from anything we can do on Earth, but we modeled sulfur combined with iron, and it seems to match what we’re seeing with XRISM,” said co-author Elisa Costantini, a senior astronomer at the Space Research Organization Netherlands and the University of Amsterdam. “Our lab has created models for different elements to compare with astronomical data for years. The campaign is ongoing, and soon we’ll have new sulfur measurements to compare with the XRISM data to learn even more.”
Iron-sulfur compounds are often found in meteorites, so scientists have long thought they might be one way sulfur solidifies out of molecular clouds to travel through the universe.
In their paper, Corrales and her team propose a few compounds that would match XRISM’s observations — pyrrhotite, troilite, and pyrite, which is sometimes called fool’s gold.
The researchers were also able to use measurements from a second X-ray binary called 4U 1630-472 that helped confirm their findings.
“NASA’s Chandra X-ray Observatory has previously studied sulfur, but XRISM’s measurements are the most detailed yet,” said Brian Williams, the XRISM project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Since GX 340+0 is on the other side of the galaxy from us, XRISM’s X-ray observations are a unique probe of sulfur in a large section of the Milky Way. There’s still so much to learn about the galaxy we call home.”
XRISM is led by JAXA (Japan Aerospace Exploration Agency) in collaboration with NASA, along with contributions from ESA (European Space Agency). NASA and JAXA developed Resolve, the mission’s microcalorimeter spectrometer.
