Electrodynamic Dust Shield Heading to Moon on Firefly Lander

Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the Moon or Mars, it is a significant hazard that must be mitigated. That’s why researchers at NASA’s Kennedy Space Center in Florida are seeking innovative ways to use the Electrodynamic Dust Shield (EDS) technology.  

The EDS technology is headed to the Moon as part of the agency’s Artemis campaign. This innovative technology will be demonstrated on the lunar surface, where it will use electrical forces to lift and remove lunar regolith, or dirt, from various surfaces.

This dust-mitigating technology is one of 10 payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency’s Kennedy Space Center in Florida Wednesday, Jan. 15, with Firefly Aerospace’s Blue Ghost Lander.

Using transparent electrodes and electric fields, EDS technology can lift and remove dust from a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. Controlling and removing the charged dust will be critical to the success of Moon missions under the agency’s CLPS initiative and Artemis campaign.  

“For these CLPS and Artemis missions, dust exposure is a concern because the lunar surface is far different than what we’re used to here,” said Dr. Charles Buhler, lead research scientist at the Electrostatics and Surface Physics Laboratory at Kennedy. “Lunar regolith dust can get into gaskets and seals, into hatches, and even into habitats, which can pose a lot of issues for spacecraft and astronauts.”  

Unlike dust particles on Earth, dust on the Moon’s surface is sharp and abrasive – like tiny shards of glass – because it hasn’t been exposed to weathering and elements like water and oxygen.  

“Simply brushing lunar regolith across surfaces can make the problem worse because it’s also very electrostatically charged and highly insulating,” Buhler said.  

Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. EDS was funded by the Space Technology Mission Directorate (STMD) Game Changing Development Program (GCD).

415 Years Ago: Astronomer Galileo Discovers Jupiter’s Moons

On Jan. 7, 1610, Italian astronomer Galileo Galilei peered through his newly improved 20-power homemade telescope at the planet Jupiter. He noticed three other points of light near the planet, at first believing them to be distant stars. Observing them over several nights, he noted that they appeared to move in the wrong direction with regard to the background stars and they remained in Jupiter’s proximity but changed their positions relative to one another. Four days later, he observed a fourth point of light near the planet with the same unusual behavior. By Jan. 15, Galileo correctly concluded that he had discovered four moons orbiting around Jupiter, providing strong evidence for the Copernican theory that most celestial objects did not revolve around the Earth.  

In March 1610, Galileo published his discoveries of Jupiter’s satellites and other celestial observations in a book titled Siderius Nuncius (The Starry Messenger). As their discoverer, Galileo had naming rights to Jupiter’s satellites. He proposed to name them after his patrons the Medicis and astronomers called them the Medicean Stars through much of the seventeenth century, although in his own notes Galileo referred to them by the Roman numerals I, II, III, and IV, in order of their distance from Jupiter. Astronomers still refer to the four moons as the Galilean satellites in honor of their discoverer.  

In 1614, the German astronomer Johannes Kepler suggested naming the satellites after mythological figures associated with Jupiter, namely Io, Europa, Ganymede, and Callisto, but his idea didn’t catch on for more than 200 years. Scientists didn’t discover any more satellites around Jupiter until 1892 when American astronomer E.E. Barnard found Jupiter’s fifth moon Amalthea, much smaller than the Galilean moons and orbiting closer to the planet than Io. It was the last satellite in the solar system found by visual observation – all subsequent discoveries occurred via photography or digital imaging. As of today, astronomers have identified 95 moons orbiting Jupiter. 

Although each of the Galilean satellites has unique features, such as the volcanoes of Io, the heavily cratered surface of Callisto, and the magnetic field of Ganymede, scientists have focused more attention on Europa due to the tantalizing possibility that it might be hospitable to life. In the 1970s, NASA’s Pioneer 10 and 11 and Voyager 1 and 2 spacecraft took ever increasingly detailed images of the large satellites including Europa during their flybys of Jupiter. The photographs revealed Europa to have the smoothest surface of any object in the solar system, indicating a relatively young crust, and also one of the brightest of any satellite indicating a highly reflective surface. These features led scientists to hypothesize that Europa is covered by an icy crust floating on a subsurface salty ocean. They further postulated that tidal heating caused by Jupiter’s gravity reforms the surface ice layer in cycles of melting and freezing.   

More detailed observations from NASA’s Galileo spacecraft that orbited Jupiter between 1995 and 2003 and completed 11 close encounters with Europa revealed that long linear features on its surface may indicate tidal or tectonic activity. Reddish-brown material along the fissures and in splotches elsewhere on the surface may contain salts and sulfur compounds transported from below the crust and modified by radiation. Observations from the Hubble Space Telescope and re-analysis of images from Galileo revealed possible plumes emanating from beneath Europa’s crust, lending credence to that hypothesis. While the exact composition of this material is not known, it likely holds clues to whether Europa may be hospitable to life.   

Future robotic explorers of Europa may answer some of the outstanding questions about this unique satellite of Jupiter. NASA’s Europa Clipper set off in October 2024 on a 5.5-year journey to Jupiter. After its arrival in 2030, the spacecraft will enter orbit around the giant planet and conduct 49 flybys of Europa during its four-year mission. Managed by the Jet Propulsion Laboratory in Pasadena, California, and the Applied Physics Laboratory at Johns Hopkins University in Baltimore, Maryland, Europa Clipper will carry nine instruments including imaging systems and a radar to better understand the structure of the icy crust. Data from Europa Clipper will complement information returned by the European Space Agency’s JUICE (Jupiter Icy Moon Explorer) spacecraft. Launched in April 2023, JUICE will first enter orbit around Jupiter in 2031 and then enter orbit around Ganymede in 2034. The spacecraft also plans to conduct studies of Europa complementary with Europa Clipper’s. The two spacecraft should greatly increase our understanding of Europa and perhaps uncover new mysteries.

NASA Lander to Test Vacuum Cleaner on Moon for Sample Collection

Among all the challenges of voyaging to and successfully landing on other worlds, the effective collection and study of soil and rock samples cannot be underestimated.

To quickly and thoroughly collect and analyze samples during next-generation Artemis Moon missions and future journeys to Mars and other planetary bodies, NASA seeks a paradigm shift in techniques that will more cost-effectively obtain samples, conduct in situ testing with or without astronaut oversight, and permit real-time sample data return to researchers on Earth.

That’s the planned task of an innovative technology demonstration called Lunar PlanetVac (LPV), one of 10 NASA payloads flying aboard the next lunar delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative. LPV will be carried to the surface by Firefly Aerospace’s Blue Ghost 1 lunar lander.

Developed by Honeybee Robotics, a Blue Origin company of Altadena, California, LPV is a pneumatic, compressed gas-powered sample acquisition and delivery system – essentially, a vacuum cleaner that brings its own gas. It’s designed to efficiently collect and transfer lunar soil from the surface to other science instruments or sample return containers without reliance on gravity. Secured to the Blue Ghost lunar lander, LPV’s sampling head will use pressurized gas to stir up the lunar regolith, or soil, creating a small tornado. If successful, material from the dust cloud it creates then will be funneled into a transfer tube via the payload’s secondary pneumatic jets and collected in a sample container. The entire autonomous operation is expected to take just seconds and maintains planetary protection protocols. Collected regolith – including particles up to 1 cm in size, or roughly 0.4 inches – will be sieved and photographed inside the sample container with the findings transmitted back to Earth in real time.

The innovative approach to sample collection and in situ testing could prove to be a game-changer, said Dennis Harris, who manages the LPV payload for the CLPS initiative at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

“There’s no digging, no mechanical arm to wear out requiring servicing or replacement – it functions like a vacuum cleaner,” Harris said. “The technology on this CLPS payload could benefit the search for water, helium, and other resources and provide a clearer picture of in situ materials available to NASA and its partners for fabricating lunar habitats and launch pads, expanding scientific knowledge and the practical exploration of the solar system every step of the way.”

Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development of seven of the 10 CLPS payloads carried on Firefly’s Blue Ghost lunar lander.

NASA Joins Telescope, Instruments to Roman Spacecraft

Technicians have successfully integrated NASA’s Nancy Grace Roman Space Telescope’s payload – the telescope, instrument carrier, and two instruments – to the spacecraft that will deliver the observatory to its place in space and enable it to function while there.

“With this incredible milestone, Roman remains on track for launch, and we’re a big step closer to unveiling the cosmos as never before,” said Mark Clampin, acting deputy associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “It’s been fantastic to watch the team’s progress throughout the integration phase. I look forward to Roman’s transformative observations.”

The newly joined space hardware will now undergo extensive testing. The first test will ensure each major element operates as designed when integrated with the rest of the observatory and establish the hardware’s combined performance. Then environmental tests will subject the payload to the electromagnetic, vibration, and thermal vacuum environments it will experience during launch and on-orbit operations. These tests will ensure the hardware and the launch vehicle will not interfere with each other when operating, verify the communications antennas won’t create electromagnetic interference with other observatory hardware, shake the assembly to make sure it will survive extreme vibration during launch, assess its performance across its expected range of operating temperatures, and make sure the instruments and mirrors are properly optically aligned.

Meanwhile, Roman’s deployable aperture cover will be integrated with the outer barrel assembly, and then the solar panels will be added before spring. Then the structure will be joined to the payload and spacecraft this fall.

The Roman mission remains on track for completion by fall 2026 and launch no later than May 2027.
