Technicians at NASA’s Payload Hazardous Servicing Facility (PHSF) at the agency’s Kennedy Space Center in Florida offloaded eight high-efficiency particulate air (HEPA) wall modules and other ground support equipment on April 27. The equipment will support launch processing of the agency’s Nancy Grace Roman Space Telescope.
Each 1,800-pound module enhances the PHSF’s clean room systems, helping meet the telescope’s stringent cleanliness requirements during its time in the facility, where the observatory will undergo key tasks such as spacecraft fueling prior to liftoff.
Roman will observe the universe in infrared light using its Wide Field Instrument and a Coronagraph Instrument technology demonstration. Its wide field of view will produce panoramic images that help astronomers investigate some of the greatest mysteries in the cosmos, including why the universe’s expansion appears to be accelerating.
By using multiple complementary techniques, Roman will chart how the universe has evolved over cosmic time and provide new insights into the nature of dark energy. Roman also will advance the study of exoplanets and map the structure and distribution of normal matter and dark matter across space and time.

Earth’s magnetic field is like a powerful trap. It lures electrically charged particles in space, near our planet, and snares them in an invisible, doughnut-shaped pen around Earth known as the ring current.
This captive swarm of charged particles plays an important role in how Earth reacts to changing conditions in space, called space weather, which can affect the technology we rely on, such as satellites and power grids. Yet there is still a lot we do not know about the ring current.
NASA is preparing to launch a mission designed to provide a unique, inside-out view of the ring current. Called STORIE (Storm Time O+ Ring current Imaging Evolution), it is scheduled to launch in May aboard the 34th SpaceX commercial resupply services mission to the International Space Station for NASA. The mission is flying as part of the Space Test Program – Houston 11 (STP-H11) payload, a partnership between the U.S. Space Force and NASA. Once it is robotically installed on the exterior of the space station (expected a few days after its arrival), STORIE will look outward at the ring current, helping scientists answer longstanding questions about how it grows and shrinks and what kind of particles it’s made of.

“These particles have important space weather impacts,” said Alex Glocer, STORIE’s principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where the instrument was designed and constructed. “We want to understand how that trapped population is built up, and where it comes from.”
These details are especially important during solar storms, when outbursts from the Sun can lead to magnetic disturbances at Earth. Similar to Earth’s Van Allen radiation belts but filled with lower-energy particles, the ring current tends to fluctuate in size, shape, and intensity more dramatically than the radiation belts do during solar storms. Plus, in the ring current, positively charged particles and negatively charged particles flow in opposite directions, creating electrical currents. So, changes there can lead to magnetic fluctuations and induced currents on the ground, potentially affecting pipelines and power lines. The ring current can also contribute to charge buildup on the surface of Earth-orbiting satellites, which can spark spacecraft glitches. Additionally, when energy ramps up in the ring current, some of that energy gets transferred to the upper atmosphere, making it heat up, puff out, and create more drag on satellites, which can cause the spacecraft to deorbit sooner than expected.
However, it’s difficult to study the ring current directly because the particles within it are invisible. “You can’t just image them with a camera,” Glocer explained.
Instead, STORIE will scan for the glow of energetic neutral atoms, or ENAs, that are formed when charged particles trapped in the ring current manage to escape. The particles earn their freedom by stealing an electron from Earth’s outer atmosphere, known as the exosphere, and become neutral.
“Once those charged particles become neutral, they no longer feel the effects of Earth’s magnetic field, and they are no longer trapped,” Glocer said. “They can just fly off in any direction.”
By measuring the speed and direction of the ENAs, STORIE could help answer longstanding questions about the origins of particles in the ring current — whether they are supplied by a stream of particles flowing out from the Sun, known as the solar wind, or from Earth.

The STORIE team designed the instrument to pay special attention to positively charged oxygen atoms (O+) because, according to Glocer, “When you see oxygen, that comes from the atmosphere. You get very little of that from the solar wind.” If STORIE finds a lot of oxygen atoms, scientists will know the ring current is largely supplied by Earth’s atmosphere, rather than the solar wind.
Glocer and other scientists also want to find out whether the ring current’s population of charged particles build up in quick bursts or slowly and gradually. “Is it like filling a lake with the steady flow of a waterfall or a bunch of raindrops?” Glocer said.
Previous NASA missions — such as IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) and TWINS (Two Wide-angle Imaging Neutral-atom Spectrometers) — have looked at ring current ENAs before using a top-down view, which allowed them to see the whole ring current at once. However, from that perspective, ultraviolet light reflected by Earth — in the center of the ring — can interfere with the ENA observations, and the viewing geometry makes it hard to see trapped particles in the ring current near Earth’s equator.
“From STORIE’s inside-out perspective, you have Earth behind you, and you can see this trapped population near the equator that was hard for other missions to observe,” Glocer said.
Some sounding rocket experiments have gotten brief, inside-out views of the ring current in the past, but they only had a few minutes to observe and could only see a portion of the ring current during each flight. The view from STORIE will reveal one slice of the ring current at a time, but as the space station orbits Earth, STORIE will build up a complete picture of the ring current roughly every 90 minutes.
Over its six-month mission, STORIE will monitor how the ring current evolves over time and allow scientists to compare its behavior during solar storms versus when the Sun is quiet. Insights from STORIE will help us better understand how Earth responds to solar storms, improve space weather predictions, and help mitigate the effects of space weather on the technology humanity depends on.

In this new picture from NASA’s Hubble Space Telescope, a spiral galaxy glittering with star clusters is the center of attention. NGC 3137 is located 53 million light-years away in the constellation Antlia (the Air Pump). As a nearby spiral galaxy, this target offers astronomers an excellent opportunity to study the cycle of stellar birth and death, as well as giving researchers a glimpse of a galactic system similar to our own.
NGC 3137 is of particular interest to astronomers because it travels through space with a group of galaxies that is thought to be similar to the Local Group, the galaxy group that contains our Milky Way. Similar to the Local Group, the NGC 3175 group contains two large spiral galaxies: NGC 3137 and NGC 3175, which Hubble has also observed. In the Local Group, the largest members are the Milky Way galaxy and Andromeda, another spiral galaxy. In addition to two large spiral galaxies, both groups also contain a number of smaller dwarf galaxies, although it’s not yet known how many of these tiny companions the NGC 3175 group has; researchers have found more than 500 dwarf galaxy candidates. By studying this nearby galaxy group, astronomers can learn about the dynamics of our own galactic home.
NGC 3137 is revealed in fantastic detail by Hubble. This image is crafted from observations in six different color bands, creating a view that highlights several facets of this beautiful spiral. The galaxy’s center, which is encircled by a network of fine, dusty clouds, hosts a black hole estimated to be 60 million times more massive than the Sun. NGC 3137 is highly inclined from our point of view, giving a unique perspective on its loose, feathery spiral structure. A couple of photobombing Milky Way stars and a smattering of far more distant background galaxies complete the image.
As stunning as each of these features may be, it’s the galaxy’s brilliant star clusters that steal the show. The galaxy is peppered with dense clusters of bright blue stars and glowing red gas clouds, which signal the presence of hot, young stars still encased in their birth nebulae.
Unsurprisingly, these star clusters are exactly what has drawn Hubble’s keen eye. Researchers are using Hubble to carry out an observing program (#17502; PI: D. Thilker) focusing on star clusters in 55 nearby galaxies. The data collected will help astronomers identify star clusters and the glowing nebulae that surround them, providing a way to measure the ages of stars in galaxies like NGC 3137. These observations give an in-depth view of stellar life in spiral galaxies, from the young stars still in the process of forming to the ancient stellar populations that grew up in the early years of their galactic hosts.
The PHANGS (Physics at High Angular Resolution in Nearby Galaxies)-HST program for which these observations were taken is part of a larger effort by some of the most powerful observatories on (and around) Earth. Hubble contributes greatly to this massive undertaking, which combines Hubble data with observations from the NASA/ESA/CSA James Webb Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA). Together, Hubble’s powerful optical and ultraviolet capabilities, Webb’s sensitive infrared eyes, and ALMA’s broad network of radio dishes bring us an unmatched view of star formation in the local universe.
