Credit: NASA NASA has selected Rocket Lab USA Inc. of Long Beach, California, to launch the agency’s Aspera mission, a SmallSat to study galaxy formation and evolution, providing new insights into how the universe works.
The selection is part of NASA’s Venture-Class Acquisition of Dedicated and Rideshare (VADR) launch services contract. This contract allows the agency to make fixed-price indefinite-delivery/indefinite-quantity launch service task order awards during VADR’s five-year ordering period, with a maximum total contract value of $300 million.
Through the observation of ultraviolet light, Aspera will examine hot gas in the space between galaxies, called the intergalactic medium. The mission will study the inflow and outflow of gas from galaxies, a process thought to contribute to star formation.
Aspera is part of NASA’s Pioneers Program in the Astrophysics Division at NASA Headquarters in Washington, which funds compelling astrophysics science at a lower cost using small hardware and modest payloads. The principal investigator for Aspera is Carlos Vargas at the University of Arizona in Tucson. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contract.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
New research suggests vast surface features on Venus called coronae continue to be shaped by tectonic processes. Observations of these features from NASA’s Magellan mission include, clockwise from top left, Artemis Corona, Quetzalpetlatl Corona, Bahet Corona, and Aine Corona.NASA/JPL-Caltech Using archival data from the mission, launched in 1989, researchers have uncovered new evidence that tectonic activity may be deforming the planet’s surface.
Vast, quasi-circular features on Venus’ surface may reveal that the planet has ongoing tectonics, according to new research based on data gathered more than 30 years ago by NASA’s Magellan mission. On Earth, the planet’s surface is continually renewed by the constant shifting and recycling of massive sections of crust, called tectonic plates, that float atop a viscous interior. Venus doesn’t have tectonic plates, but its surface is still being deformed by molten material from below.
Seeking to better understand the underlying processes driving these deformations, the researchers studied a type of feature called a corona. Ranging in size from dozens to hundreds of miles across, a corona is most often thought to be the location where a plume of hot, buoyant material from the planet’s mantle rises, pushing against the lithosphere above. (The lithosphere includes the planet’s crust and the uppermost part of its mantle.) These structures are usually oval, with a concentric fracture system surrounding them. Hundreds of coronae are known to exist on Venus.
Published in the journal Science Advances, the new study details newly discovered signs of activity at or beneath the surface shaping many of Venus’ coronae, features that may also provide a unique window into Earth’s past. The researchers found the evidence of this tectonic activity within data from NASA’s Magellan mission, which orbited Venus in the 1990s and gathered the most detailed gravity and topography data on the planet currently available.
“Coronae are not found on Earth today; however, they may have existed when our planet was young and before plate tectonics had been established,” said the study’s lead author, Gael Cascioli, assistant research scientist at the University of Maryland, Baltimore County, and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “By combining gravity and topography data, this research has provided a new and important insight into the possible subsurface processes currently shaping the surface of Venus.”
This artist’s concept of the large Quetzalpetlatl Corona located in Venus’ southern hemisphere depicts active volcanism and a subduction zone, where the foreground crust plunges into the planet’s interior. A new study suggests coronae are the locations of several types of tectonic activity.NASA/JPL-Caltech/Peter Rubin As members of NASA’s forthcoming VERITAS (Venus Emissivity, Radio science, InSAR, Topography, and Spectroscopy) mission, Cascioli and his team are particularly interested in the high-resolution gravity data the spacecraft will provide. Study coauthor Erwan Mazarico, also at Goddard, will co-lead the VERITAS gravity experiment when the mission launches no earlier than 2031.
Mystery Coronae
Managed by NASA’s Jet Propulsion Laboratory in Southern California, Magellan used its radar system to see through Venus’ thick atmosphere and map the topography of its mountains and plains. Of the geological features the spacecraft mapped, coronae were perhaps the most enigmatic: It wasn’t clear how they formed. In the years since, scientists have found many coronae in locations where the planet’s lithosphere is thin and heat flow is high.
“Coronae are abundant on Venus. They are very large features, and people have proposed different theories over the years as to how they formed,” said coauthor Anna Gülcher, Earth and planetary scientist at the University of Bern in Switzerland. “The most exciting thing for our study is that we can now say there are most likely various and ongoing active processes driving their formation. We believe these same processes may have occurred early in Earth’s history.”
The researchers developed sophisticated 3D geodynamic models that demonstrate various formation scenarios for plume-induced coronae and compared them with the combined gravity and topography data from Magellan. The gravity data proved crucial in helping the researchers detect less dense, hot, and buoyant plumes under the surface — information that couldn’t be discerned from topography data alone. Of the 75 coronae studied, 52 appear to have buoyant mantle material beneath them that is likely driving tectonic processes.
One key process is subduction: On Earth, it happens when the edge of one tectonic plate is driven beneath the adjacent plate. Friction between the plates can generate earthquakes, and as the old rocky material dives into the hot mantle, the rock melts and is recycled back to the surface via volcanic vents.
These illustrations depict various types of tectonic activity thought to persist beneath Venus’ coronae. Lithospheric dripping and subduction are shown at top; below are and two scenarios where hot plume material rises and pushes against the lithosphere, potentially driving volcanism above it.Anna Gülcher, CC BY-NC On Venus, a different kind of subduction is thought to occur around the perimeter of some coronae. In this scenario, as a buoyant plume of hot rock in the mantle pushes upward into the lithosphere, surface material rises and spreads outward, colliding with surrounding surface material and pushing that material downward into the mantle.
Another tectonic process known as lithospheric dripping could also be present, where dense accumulations of comparatively cool material sink from the lithosphere into the hot mantle. The researchers also identify several places where a third process may be taking place: A plume of molten rock beneath a thicker part of the lithosphere potentially drives volcanism above it.
Deciphering Venus
This work marks the latest instance of scientists returning to Magellan data to find that Venus exhibits geologic processes that are more Earth-like than originally thought. Recently, researchers were able to spot erupting volcanoes, including vast lava flows that vented from Maat Mons, Sif Mons, and Eistla Regio in radar images from the orbiter.
While those images provided direct evidence of volcanic action, the authors of the new study will need sharper resolution to draw a complete picture about the tectonic processes driving corona formation. “The VERITAS gravity maps of Venus will boost the resolution by at least a factor of two to four, depending on location — a level of detail that could revolutionize our understanding of Venus’ geology and implications for early Earth,” said study coauthor Suzanne Smrekar, a planetary scientist at JPL and principal investigator for VERITAS.
Managed by JPL, VERITAS will use a synthetic aperture radar to create 3D global maps and a near-infrared spectrometer to figure out what the surface of Venus is made of. Using its radio tracking system, the spacecraft will also measure the planet’s gravitational field to determine the structure of Venus’ interior. All of these instruments will help pinpoint areas of activity on the surface.

As NASA partners with American industry to deliver science and technology payloads to the Moon, a dedicated team behind the scenes ensures every mission is grounded in strategy, compliance, and innovation. Leading that effort is Aubrie Henspeter, who advises all aspects of procurement for NASA’s Commercial Lunar Payload Services (CLPS) initiative—one of the cornerstone projects supporting the Artemis campaign.
Official portrait of Aubrie Henspeter. NASA/Bill Stafford With 20 years at NASA, Henspeter brings multifaceted experience to her role as CLPS procurement team lead in the Lunar & Planetary Exploration Procurement Office at Johnson Space Center in Houston. Her job is equal parts problem-solving, mentoring, and strategizing—all focused on enabling commercial partners to deliver NASA payloads to the lunar surface faster, more affordably, and more efficient than ever before.
“It’s been a great experience to see the full lifecycle of a project—from soliciting requirements to launching to the Moon,” said Henspeter. “We work to continuously adjust as the lunar industry grows and improve procurement terms and conditions by incorporating lessons learned.”
Henspeter leads a team of six contracting officers and contract specialists, managing workload priorities and supporting the continuity of seven commercial missions currently on contract. She also helps shape upcoming contract opportunities for future lunar deliveries, constantly seeking creative procurement strategies within a commercial firm-fixed-price framework.
NASA launched the CLPS initiative in 2018 to create a faster, more flexible way to partner with commercial companies for lunar deliveries. Thirteen vendors are participating as part of a multi-award contract, each eligible to compete for individual task orders to deliver NASA science and technology payloads to the Moon. These deliveries support Artemis goals by enabling new discoveries, testing key technologies, and preparing for long-term human exploration on the lunar surface.
Aubrie Henspeter receives the 2023 JSC Director’s Commendation Award from NASA Acting Associate Administrator Vanessa Wyche, right, and Johnson Space Center’s Acting Director Steve Koerner, far left, joined by her sons Elijah and Malik Merrick.NASA/James Blair In May 2023, Henspeter received the NASA Exceptional Service Medal for her leadership on CLPS from 2018–2023. For her, the recognition reflects the team’s spirit and collaboration.
“I genuinely enjoy working on this project because of its lean, adaptable approach and the amazing team involved,” she said. “When all of us across NASA work together we are the most successful and can achieve our mission.”
That sense of collaboration and adaptability has shaped many of the insights Henspeter has gained throughout her career—lessons she now applies daily to help the team stay aligned and prepared.
One of those key lessons: always keep the contract current.
“It’s all good until it isn’t, and then everyone asks—what does the contract say?” she said. “Open communication and up-to-date documentation, no matter how minor the change, are essential.”
Over the course of her career, Henspeter has learned to prioritize preparation, adaptability, and strong working relationships.
“Preparation in procurement is conducting thorough market research, understanding the regulations, finding the gray areas, and developing a strategy that best meets the customer’s needs,” she said. “Adaptability means staying committed to the goal while remaining open and flexible on how to get there.”
That philosophy has helped her navigate everything from yearlong international contract negotiations with foreign partners to pivoting a customer from a sole-source request to a competitive procurement that ultimately saved costs and expanded opportunity.
“NASA is full of brilliant people, and it can be challenging to present alternatives. But through clear communication and data-driven recommendations, we find solutions that work,” Henspeter said.

As she looks to the Artemis Generation, Henspeter hopes to pass along a deep respect for teamwork and shared purpose.
“Every contribution matters. Whether it seems big or small, it makes a difference in achieving our mission,” she said. “I take pride in my role and in being part of the NASA team.”

4 Min Read NASA Expands SPHEREx Science Return Through Commercial Partnership
A sectional rendering of NASA's SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer). Credits: NASA NASA is partnering with commercial industry to expand our knowledge of Earth, our solar system, and beyond. Recently, NASA collaborated with Kongsberg Satellite Services (KSAT) to support data transfer for the agency’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) mission to explore the origins of the universe.
“Not only is NASA moving toward commercialization, the agency is making technological advancements to existing systems and saving millions of dollars in the process — all while expanding human knowledge through science and exploration missions,” said Kevin Coggins, associate administrator for NASA’s SCaN (Space Communications and Navigation) program.
To receive data from missions in space, NASA relies on the Near Space Network and Deep Space Network, a collection of antennas around the globe.
In preparation for the recently-launched SPHEREx observatory, NASA needed to upgrade an antenna on the world’s most remote continent: Antarctica.
Transmitted via NASA’s Near Space Network, this video shows SPHEREx scanning a region of the Large Magellanic Cloud. The shifting colors represent different infrared wavelengths detected by the telescope’s two arrays. Credit: NASA/JPL-Caltech NASA’s SCaN program took a novel approach by leveraging its established commercial partnership with KSAT. While upgraded KSAT antennas were added to the Near Space Network in 2023, SPHEREx required an additional Antarctic antenna that could link to online data storage.
To support SPHEREx’s polar orbit, KSAT upgraded its Troll, Antarctica antenna and incorporated their own cloud storage system. NASA then connected KSAT’s cloud to the NASA cloud, DAPHNE+ (Data Acquisition Process and Handling Environment).
As the Near Space Network’s operational cloud services system, DAPHNE+ enables science missions to transmit their data to the network for virtual file storage, processing, and management.
“By connecting the Troll antenna to DAPHNE+, we eliminated the need for large, undersea fiberoptic cables by virtually connecting private and government-owned cloud systems, reducing the project’s cost and complexity,” said Matt Vincent, the SPHEREx mission manager for the Near Space Network at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
Each day, SPHEREx downlinks a portion of its 20 gigabits of science data through the Troll antenna, which transfers the files across KSAT’s network of relay satellites to the DAPHNE+ cloud. The cloud system combines and centralizes the data from each antenna, allowing access to all of SPHEREx’s health and science data in one convenient place.
The SPHEREx mission data is transmitted from space to the Troll Satellite Station, relayed through a network of satellites, and stored in the Near Space Network’s cloud system for easily-accessible analysis by scientists around the world.NASA/Dave Ryan With coverage throughout its orbit, SPHEREx transmits its 3D maps of the celestial sky, offering new insight into what happened a fraction of a second after the big bang.
“Missions like SPHEREx use the Near Space Network’s combination of commercial and government antennas,” explained Michael Skube, DAPHNE+ manager at NASA Goddard. “And that is the benefit of DAPHNE+ — it enables the network to pull different sources of information into one central location. The DAPHNE+ system treats government and commercial antennas as part of the same network.”
The partnership is mutually beneficial. NASA’s Near Space Network maintains a data connection with SPHEREx as it traverses both poles and KSAT benefits from its antennas’ integration into a robust global network – no new cables required.
“We were able to find a networking solution with KSAT that did not require us to put additional hardware in Antarctica,” said Vincent. “Now we are operating with the highest data rate we have ever downlinked from that location.”
The upgraded ground station antenna at Troll Satellite Station supports cloud-based space communications, enabling NASA’s Near Space Network to support scientific missions via a wireless cloud network.Kongsberg Satellite Services For NASA, its commercial partners, and other global space agencies, this expansion means more reliable space communications with fewer expenses.
Troll’s successful integration into the Near Space Network is a case study for future private and government partnerships. As SPHEREx measures the collective glow of over 450 million galaxies as far as 10 billion light-years away, SCaN continues to innovate how its discoveries safely return to Earth.
The SPHEREx mission is managed by NASA’s Jet Propulsion Laboratory in Southern California for the agency’s Astrophysics Division within the Science Mission Directorate at NASA Headquarters. Data will be processed and archived at IPAC at Caltech. The SPHEREx dataset will be publicly available at the NASA-IPAC Infrared Science Archive. Funding and oversight for DAPHNE+ and the Near Space Network come from the SCaN program office at NASA Headquarters and operate out of NASA’s Goddard Space Flight Center. The Troll Satellite Station is owned and operated by Kongsberg Satellite Services and located in Queen Maud Land, Antarctica.
