Hubble Captures Young Stars Changing Their Environments
This NASA/ESA Hubble Space Telescope image features the nearest star-forming region to Earth, the Orion Nebula (Messier 42, M42), located some 1,500 light-years away. ESA/Hubble, NASA, and T. Megeath This NASA/ESA Hubble Space Telescope image peers into the dusty recesses of the nearest massive star-forming region to Earth, the Orion Nebula (Messier 42, M42). Just 1,500 light-years away, the Orion Nebula is visible to the unaided eye below the three stars that form the ‘belt’ in the constellation Orion. The nebula is home to hundreds of newborn stars including the subject of this image: the protostars HOPS 150 and HOPS 153.
These protostars get their names from the Herschel Orion Protostar Survey, conducted with ESA’s Herschel Space Observatory. The object visible in the upper-right corner of this image is HOPS 150: it’s a binary star system where two young protostars orbit each other. Each star has a small, dusty disk of material surrounding it. These stars gather material from their respective dust disks, growing in the process. The dark line that cuts across the bright glow of these protostars is a cloud of gas and dust falling in on the pair of protostars. It is over 2,000 times wider than the distance between Earth and the Sun. Based on the amount of infrared light HOPS 150 is emitting, as compared to other wavelengths it emits, the protostars are mid-way down the path to becoming mature stars.
Extending across the left side of the image is a narrow, colorful outflow called a jet. This jet comes from the nearby protostar HOPS 153, which is out of the frame. HOPS 153 is significantly younger than its neighbor. That stellar object is still deeply embedded in its birth nebula and enshrouded by a cloud of cold, dense gas. While Hubble cannot penetrate this gas to see the protostar, the jet HOPS 153 emitted is brightly and clearly visible as it plows into the surrounding gas and dust of the Orion Nebula.
The transition from tightly swaddled protostar to fully fledged star will dramatically affect HOPS 153’s surroundings. As gas falls onto the protostar, its jets spew material and energy into interstellar space, carving out bubbles and heating the gas. By stirring up and warming nearby gas, HOPS 153 may regulate the formation of new stars in its neighborhood and even slow its own growth.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Danah Tommalieh, commercial pilot and engineer at Reliable Robotics, inputs a flight plan at the control center in Mountain View, California, ahead of remotely operating a Cessna 208 aircraft at Hollister municipal airport in Hollister, California.NASA/Don Richey NASA recently began a series of flight tests with partners to answer an important aviation question: What will it take to integrate remotely piloted or autonomous planes carrying large packages and cargo safely into the U.S. airspace? Researchers tested new technologies in Hollister, California, that are helping to investigate what tools and capabilities are needed to make these kinds of flights routine.
The commercial industry continues to make advancements in autonomous aircraft systems aimed at making it possible for remotely operated aircraft to fly over communities – transforming the way we will transport people and goods. As the Federal Aviation Administration (FAA) develops standards for this new type of air transportation, NASA is working to ensure these uncrewed flights are safe by creating the required technological tools and infrastructure. These solutions could be scaled to support many different remotely piloted aircraft – including air taxis and package delivery drones – in a shared airspace with traditional crewed aircraft.
“Remotely piloted aircraft systems could eventually deliver cargo and people to rural areas with limited access to commercial transportation and delivery services,” said Shivanjli Sharma, aerospace engineer at NASA’s Ames Research Center in California’s Silicon Valley. “We’re aiming to create a healthy ecosystem of many different kinds of remotely piloted operations. They will fly in a shared airspace to provide communities with better access to goods and services, like medical supply deliveries and more efficient transportation.”
During a flight test in November, Reliable Robotics, a company developing an autonomous flight system, remotely flew its Cessna 208 Caravan aircraft through pre-approved flight paths in Hollister, California.
Although a safety pilot was aboard, a Reliable Robotics remote pilot directed the flight from their control center in Mountain View, more than 50 miles away.

Researchers evaluated a Collins Aerospace ground-based surveillance system’s ability to detect nearby air traffic and provide the remote pilot with information in order to stay safely separated from other aircraft in the future.
Initial analysis shows the ground-based radar actively surveilled the airspace during the aircraft’s taxi, takeoff, and landing. The data was transmitted from the radar system to the remote pilot at Reliable Robotics. In the future, this capability could help ensure aircraft remain safely separated across all phases of fight.

A Reliable Robotics pilot operated the aircraft remotely from the control center in Mountain View.NASA/Brandon Torres Naverrete While current FAA operating rules require pilots to physically see and avoid other aircraft from inside the cockpit, routine remotely piloted aircraft will require a suite of integrated technologies to avoid hazards and coordinate with other aircraft in the airspace.
A radar system for ground-based surveillance offers one method for detecting other traffic in the airspace and at the airport, providing one part of the capability to ensure pilots can avoid collision and accomplish their desired missions. Data analysis from this testing will help researchers understand if ground-based surveillance radar can be used to satisfy FAA safety rules for remotely piloted flights.
NASA will provide analysis and reports of this flight test to the FAA and standards bodies.
“This is an exciting time for the remotely piloted aviation community,” Sharma said. “Among other benefits, remote operations could provide better access to healthcare, bolster natural disaster response efforts, and offer more sustainable and effective transportation to both rural and urban communities. We’re thrilled to provide valuable data to the industry and the FAA to help make remote operations a reality in the near future.”
Over the next year, NASA will work with additional aviation partners on test flights and simulations to test weather services, communications systems, and other autonomous capabilities for remotely piloted flights. NASA researchers will analyze data from these tests to provide a comprehensive report to the FAA and the community on what minimum technologies and capabilities are needed to enable and scale remotely piloted operations.
This flight test data analysis is led out of NASA Ames under the agency’s Air Traffic Management Exploration project. This effort supports the agency’s Advanced Air Mobility mission research, ensuring the United States stays at the forefront of aviation innovation.

NASA White Sands Test Facility
Las Cruces, New Mexico
Soil Remediation at the 600 Area Off-Site Pile
Origins of the 600 Area Off-Site Pile
The NASA White Sands Test Facility (WSTF) is crucial for supporting space exploration and technology development. Located in New Mexico, it provides a controlled environment for testing and evaluating spacecraft, propulsion systems, and other aerospace technologies. The facility is instrumental in conducting critical tests such as engine firings, thermal and environmental testing, and materials research. Its role in ensuring the safety, reliability, and performance of spacecraft and systems makes it a key asset in NASA’s mission to explore space and advance scientific knowledge. Unfortunately, past practices associated with the execution of its mission adversely impacted soil and groundwater resources.
From June 1974 to December 1979, sludge and soil removed from a domestic and industrial wastewater lagoon was stockpiled on Bureau of Land Management land west of the NASA White Sands Test Facility (WSTF) facility boundary, less than a mile from the lagoon. When accumulation of material ceased, the sludge/soil debris pile lay dormant with no boundary identification. In 1993, during a Resource Conservation and Recovery Act field investigation the debris pile was identified and reported to the New Mexico Environment Department (NMED) and designated as Solid Waste Management Unit (SWMU) 16.
Investigation Summary
Initial investigations were completed at SWMU 16 in 2015 and 2018 to characterize the stockpiled sludge/soil and native soils beneath the stockpile to a depth of 30 feet. Analysis of soil sample data indicated the contaminants in the pile posed a risk to human health and the environment due to identified concentrations of nitrates, metals, volatile and semi-volatile organics, pesticides, polychlorinated biphenyls, and dioxins and furans. The NMED agreed to the removal and off-site disposal of New Mexico Special Waste in 2021.
Removal, Disposal, Confirmation Sampling
Excavation of the stockpile and the upper 6 inches of native soil was completed in January 2024. Excavation of native soils extended approximately 10 ft beyond the extent of the pile. A total of 1,072.7 tons of sludge and soil were disposed at the Corralitos Landfill. In February 2024, confirmatory soil samples were collected from 38 locations on a 30-foot grid established across SWMU 16, encompassing the location of the removed stockpile and all areas potentially affected by site operations. These samples were submitted for laboratory chemical analyses to determine if NASA had met is remedial objectives and eliminated the exposure risk to human health and the environment.
Risk Assessment
The results showed that NASA had succeeded. The site was restored. Results of soil sample analyses did not identify site contaminants remain at the site, and a risk assessment did not identify elevated risk to receptors or to groundwater beneath the site. NASA concluded that site contaminants have been removed, the risk to human health and the environment are below regulatory targets. NASA recommended a change in site status from “Requiring Corrective Action” to “Corrective Action Complete without Controls”. The report of results is currently under review by the NMED.

At the edge of Las Cruces, New Mexico, surrounded by miles of sunbaked earth, NASA’s White Sands Test Facility (WSTF) is quietly shaping the future. There is no flash, no fanfare — the self-contained facility operates as it has since 1962, humbly and in relative obscurity.
Yet as New Mexico’s space industry skyrockets amid intensifying commercial spaceflight efforts across the state, WSTF feels a new urgency to connect with the community. With the facility’s latest Test and Evaluation Support Team (TEST3) contract now in its third year, Program Manager Michelle Meerscheidt is determined to make a mark.
“I think it’s very important we increase our public presence,” Meerscheidt said. “We are a significant contributor to NASA’s mission and our country’s aspirations for furthering space exploration.”
In September, TEST3 leadership joined forces with the City of Las Cruces to support the sixth annual Las Cruces Space Festival, a two-weekend celebration of the region’s rich relationship with the aerospace industry.
The Test and Evaluation Support Team (TEST3) team — Human Resources Manager Kristina Garcia (left), Program Manager Michelle Meerscheidt, and Deputy Program Manager/Business Manager Karen Lucht — prepares to meet with visitors at the Las Cruces Space Festival Astronomy & Industry Night on Sept. 13, 2024, in Las Cruces, New Mexico. NASA/Anthony Luis Quiterio Alongside WSTF, festival director Alice Carruth is working to open a world that many believe is off limits and others don’t know exists.
“Unless you’re driving over the mountains regularly and seeing the sign that says, ‘The Birthplace of the U.S. Space and Missile Program,’ you don’t tend to know what’s going on in your backyard,” Carruth said.
“The whole premise of the Space Festival is to make people understand what’s going on in their community, to encourage people to think about careers in the space industry, and to inspire the next generation.”
A featured speaker at the festival’s New Mexico State University Astronomy & Industry Night, Meerscheidt had the chance to do just that.
“It’s fun to see a lot of young kids that are wide-eyed and excited,” Meerscheidt said. “It’s nice to be able to encourage them to pursue their dreams.”
Among those wide-eyed festivalgoers was 6-year-old Camilla Medina-Bond, who was confident in her vision for the future.
“I want to be an astronaut when I grow up,” she said. “I want to visit the Moon.”
As for the details of her lunar mission, Medina-Bond’s plan is simple: “Just going to see what’s on it.” She has plenty of time to figure out the specifics — after all, giant leaps start with small steps. According to Meerscheidt, the aspiring astronaut has already taken the first and most critical step.
“That’s what NASA is all about,” Meerscheidt said. “Explore, be inquisitive. Open your mind, open your imagination, and go for it.”

Right: Medina-Bond immerses herself in another world as she operates a virtual reality headset. NASA/Anthony Luis Quiterio Medina-Bond’s aspiration is shared by many young dreamers. A 2024 global study by longtime NASA partner, the LEGO Group, found 77% of kids ages 4-14 want to travel to space.
Carruth acknowledged that keeping the attention of today’s always-scrolling, trend-driven generation is not easy, and that children’s fascination with space often wanes as they age.
“If you look at the statistics, space tends to be really cool until they get to middle school level, and then space isn’t cool anymore — not because it’s not cool, but because it then becomes inaccessible to a lot of students,” she said.
Still, Carruth is prepared to navigate the challenge.
“I want kids to understand that space is for everybody,” Carruth said. “I also want their parents and grandparents to understand why space is important and that this is a feasible career.”
Oscar Castrejon, who attended the festival with his 12-year-old son, Oscar Jr., is on his own mission to nurture that understanding. “I’ve learned early kids need to develop their own passions, but if they say ‘hey, I like this, I’m interested in it,’ then I’ll take them to it,” Castrejon said. “If their eyes get opened, if their imagination gets sparked, you never know — you could be looking at the next NASA scientist.”
Oscar Castrejon and his son Oscar Jr., age 12, stop by the White Sands TEST3 booth. Anthony Luis Quiterio WSTF TEST3 Deputy Program Manager and Business Manager Karen Lucht shares Castrejon’s philosophy, emphasizing the importance of authenticity.
“Speak[ing] to who you are as a person will ultimately lead to who you will become as a professional,” she said.
A remote test site, WSTF has its own ecosystem which Lucht compares to a “small city.” Among its residents are scientists and engineers, but also welders, writers, firefighters, and photographers — to name a few.
“White Sands offers endless opportunities for everybody,” Lucht said. “Every career has a path here.”
Lucht’s own journey illustrates the infinite potential that arises in diverse spaces like WSTF.
“I came from a town of less than a thousand people, and I never dreamt that I would work for NASA,” she said. “As someone who was told many times that I would never make it to my position, I look back on my career and realize there are no restraints. You really can do anything you want to do.”
For those wanting to join the ranks at WSTF, there is one important requirement: they must see themselves as stardust, a vital element in a grand cosmic plan.
“We’re looking for people who have the right perspective, the desire to learn and contribute to something bigger than themselves,” Lucht said.
At WSTF — a place where the stars feel close enough to touch — the sky is not the limit, it is only the beginning.
