Preparations for Next Moonwalk Simulations Underway (and Underwater)
The six SCALPSS cameras mounted around the base of Blue Ghost will collect imagery during and after descent and touchdown. Using a technique called stereo photogrammetry, researchers at Langley will use the overlapping images to produce a 3D view of the surface. Image courtesy of Firefly. Say cheese again, Moon. We’re coming in for another close-up.
For the second time in less than a year, a NASA technology designed to collect data on the interaction between a Moon lander’s rocket plume and the lunar surface is set to make the long journey to Earth’s nearest celestial neighbor for the benefit of humanity.
Developed at NASA’s Langley Research Center in Hampton, Virginia, Stereo Cameras for Lunar Plume-Surface Studies (SCALPSS) is an array of cameras placed around the base of a lunar lander to collect imagery during and after descent and touchdown. Using a technique called stereo photogrammetry, researchers at Langley will use the overlapping images from the version of SCALPSS on Firefly’s Blue Ghost — SCALPSS 1.1 — to produce a 3D view of the surface. An earlier version, SCALPSS 1.0, was on Intuitive Machines’ Odysseus spacecraft that landed on the Moon last February. Due to mission contingencies that arose during the landing, SCALPSS 1.0 was unable to collect imagery of the plume-surface interaction. The team was, however, able to operate the payload in transit and on the lunar surface following landing, which gives them confidence in the hardware for 1.1.
The SCALPSS 1.1 payload has two additional cameras — six total, compared to the four on SCALPSS 1.0 — and will begin taking images at a higher altitude, prior to the expected onset of plume-surface interaction, to provide a more accurate before-and-after comparison.
These images of the Moon’s surface won’t just be a technological novelty. As trips to the Moon increase and the number of payloads touching down in proximity to one another grows, scientists and engineers need to be able to accurately predict the effects of landings.
How much will the surface change? As a lander comes down, what happens to the lunar soil, or regolith, it ejects? With limited data collected during descent and landing to date, SCALPSS will be the first dedicated instrument to measure the effects of plume-surface interaction on the Moon in real time and help to answer these questions.
“If we’re placing things – landers, habitats, etc. – near each other, we could be sand blasting what’s next to us, so that’s going to drive requirements on protecting those other assets on the surface, which could add mass, and that mass ripples through the architecture,” said Michelle Munk, principal investigator for SCALPSS and acting chief architect for NASA’s Space Technology Mission Directorate at NASA Headquarters in Washington. “It’s all part of an integrated engineering problem.”
Under the Artemis campaign, the agency’s current lunar exploration approach, NASA is collaborating with commercial and international partners to establish the first long-term presence on the Moon. On this CLPS (Commercial Lunar Payload Services) initiative delivery carrying over 200 pounds of NASA science experiments and technology demonstrations, SCALPSS 1.1 will begin capturing imagery from before the time the lander’s plume begins interacting with the surface until after the landing is complete.
The final images will be gathered on a small onboard data storage unit before being sent to the lander for downlink back to Earth. The team will likely need at least a couple of months to
process the images, verify the data, and generate the 3D digital elevation maps of the surface. The expected lander-induced erosion they reveal probably won’t be very deep — not this time, anyway.
One of the SCALPSS cameras is visible here mounted to the Blue Ghost lander.Image courtesy of Firefly. “Even if you look at the old Apollo images — and the Apollo crewed landers were larger than these new robotic landers — you have to look really closely to see where the erosion took place,” said Rob Maddock, SCALPSS project manager at Langley. “We’re anticipating something on the order of centimeters deep — maybe an inch. It really depends on the landing site and how deep the regolith is and where the bedrock is.”
But this is a chance for researchers to see how well SCALPSS will work as the U.S. advances human landing systems as part of NASA’s plans to explore more of the lunar surface.
“Those are going to be much larger than even Apollo. Those are large engines, and they could conceivably dig some good-sized holes,” said Maddock. “So that’s what we’re doing. We’re collecting data we can use to validate the models that are predicting what will happen.”
The SCALPSS 1.1 project is funded by the Space Technology Mission Directorate’s Game Changing Development Program.
NASA is working with several American companies to deliver science and technology to the lunar surface under the CLPS initiative. Through this opportunity, various companies from a select group of vendors bid on delivering payloads for NASA including everything from payload integration and operations, to launching from Earth and landing on the surface of the Moon.

Jovian Vortex Hunters Spun Up Over New Paper
Jumping Jupiter! The results are in, storm chasers! Thanks to your help over the last two years the Jovian Vortex Hunter project has published a catalog of 7222 vortices, which you can download here. Each vortex is an enormous swirling windstorm in Jupiter’s atmosphere–terrifying yet beautiful to behold.
The vortices are labeled by color (“white” is most common, then “dark”, then “red”).
The catalog reveals distributions of vortex sizes, aspect ratios, and locations on the planet. For example, your work showed that white and dark vortices are preferentially found near the poles. These distributions help researchers derive general parameters about Jupiter’s atmosphere that can give us insights about its internal processes and the atmospheres of other planets.
Over 5,000 of you helped build this catalog by performing over a million classifications of images of Jupiter from the JunoCam instrument on NASA’s Juno mission. The details of the catalog are now published in this paper in the Planetary Science Journal. You can also learn more about this amazing volunteer effort in a video you can find on the Jovian Vortex Hunter Results webpage.Thanks to your efforts, The Jovian Vortex Hunter project is out of data. But you can work with JunoCam data in a different way by participating in NASA’s JunoCam citizen science project.

NASA’s Night Sky Network is one of the most successful and longstanding grassroots initiatives for public engagement in astronomy education. Started in 2004 with the PlanetQuest program out of the Jet Propulsion Laboratory and currently supported by NASA’s Science Activation, the Night Sky Network (NSN) plays a critical role in fostering science literacy through astronomy. By connecting NASA science and missions to support amateur astronomy clubs, NSN leverages the expertise and enthusiasm of club members, who bring this knowledge to schools, museums, observatories, and other organizations, bridging the gap between NASA science and the public. Now in its 20th year, NSN supports over 400 astronomy clubs dedicated to bringing the wonder of the night sky to their communities across the US, connecting with 7.4 million people across the United States and its territories since its inception.

It all started with an idea – astronomy clubs already do great outreach, and club members know a lot of astronomy (shown definitively by founder Marni Berendsen’s research), and they love to talk with the public – how could NASA support these astronomy clubs in sharing current research and ideas using informal activities designed for use in the places that amateur astronomers do outreach. Thanks to funding through NASA JPL’s PlanetQuest public engagement program, the Night Sky Network was born in 2004, with more than 100 clubs joining the first year.

Connecting what we do with our missions to the sense of wonder that comes when you look up at the stars and the planets is one of our long-term objectives. We have a strong commitment to inspiring the next generation of explorers. Lending support to the energy that the amateur astronomy community brings to students and the public will allow NASA to reach many more people.”
Taking off like a rocket, Night Sky Network had over 100 clubs registered on their website within the first year.
The Toolkits
Outreach Toolkits were developed to assist clubs with their endeavors. These kits included educational materials, hands-on activities, and guides to explaining topics in an accessible way. So far, 13 toolkits have been created with topics ranging from the scale of the universe to how telescopes work. To qualify for these free Toolkits, clubs must be active in their communities, hosting two outreach events every three months or five outreach events within a calendar year. Supplemental toolkits were also created based on special events, such as the solar eclipses and the 50th anniversary of Apollo’s Moon landing. A new toolkit is in development to teach audiences about solar science, and NSN is on track to support clubs well into the future.
Rye Science Day, October 2014 Credit: Southern Colorado Astronomical Society/Malissa Pacheco NSN also hosts archived video trainings on these toolkits and other topics via its YouTube channel and a monthly webinar series with scientists from various institutions worldwide. Lastly, a monthly segment called Night Sky Notes is produced for clubs to share with their audiences via newsletters and mailing lists.
Sharing the Universe
In 2007, a National Science Foundation grant provided funding for further research into astronomy club needs. From that came three resources for clubs – the Growing Your Astronomy Club and Getting Started with Outreach video series, as well as an updated website with a national calendar and club and event coordination. Now you can find hundreds of events each month across the country, including virtual events that you can join from anywhere.

Since late November 2024 there is something is going on and no one has the answer to why there are ongoing incursions of unidentified drones over U.S. and U.K. military bases, nuclear installations and areas such as New Jersey and Manchester Airport.
For example, over the past 72 hours, again there have been numerous reports of large, car-sized drones or UFOs seen in the US (New Jersey, Arizona, North Carolina, Texas) and the UK too.
These drones often flying in formations displaying advanced capabilities such as coordination, range, endurance, and the ability to evade detection and interception. Despite multiple sightings, none have been recovered or identified, and no physical descriptions or origins have been confirmed.
Key details:
Activity: The drones have penetrated restricted airspace repeatedly, often in swarms of a dozen or more.
Capabilities: The drones exhibit advanced coordination and endurance, suggesting sophisticated technology.
Response: The U.S. Air Force acknowledges the incursions but states that they have not disrupted operations. Investigations are ongoing in collaboration with U.K. authorities.
Speculation: Potential origins range from Russia or China to commercial or recreational sources. However, their behavior and capabilities seem to exceed typical drone technology. Even there is speculation about an upcoming false flag alien/UFO invasion.
Government Inaction: Criticism is directed at the Pentagon and other authorities for not addressing the issue or taking action to remove the objects, especially given their proximity to critical infrastructure.
The FBI and other authorities are reportedly focused on potential UFO or drone activities, particularly on or around December 3rd, which some claim was predicted to be significant by an individual known for accurately forecasting the 2003 Indonesian tsunami.
Media Suppression: Reports indicate that some footage and discussions about the sightings have been censored or removed.
Historical Context: The events resemble past UFO sightings at military installations, such as the 1975 U.S. military base incursions, where objects displayed extraordinary flight capabilities and eluded interception.
The situation remains unresolved, raising questions about the drones' origins, purpose, and implications for military security.
Whether they are advanced foreign drones or something more extraordinary, the lack of evidence and official explanations fuels speculation whether these sightings represent a security threat.
More information is awaited from ongoing investigations and official responses.
