The Moon Landing That Made Boston University Historical past | The Brink

At 2 am on a Sunday in March 2025, a dozen scientists had been gathered in a College of Engineering lab at Boston University in a tense, nail-biting silence. Almost 240,000 miles away, a shiny, golden spacecraft was slowly dropping towards the moon’s floor after touring via area for 40 days. Mounted on high was a specifically designed telescope, constructed at BU and generally known as LEXI, despatched to seize views of Earth’s protecting magnetic discipline which have by no means been seen earlier than. 

They waited in anticipation. Would the spacecraft land gently on the best spot? If it did, wouldn’t it keep upright? Would it crash and destroy years of their work within the blink of an eye fixed? 

Nothing was sure. Moon landings are notoriously difficult feats. In 2024, a NASA-funded lander made by Intuitive Machines tipped on its side after touchdown quicker than anticipated.

But by 2:30 am EST on March 2, 2025, the researchers received the information they’d been ready—hoping—for.

“NASA, we are on the moon,” got here a voice, as all eyes had been on the mission’s laptop techniques used to speak with the instrument and the spacecraft.

Project head Brian Walsh, an ENG affiliate professor of mechanical engineering, straightened up and smacked his fingers collectively, his face awash in reduction. Others cheered and let loose their breath. 

“We’re thrilled to reach this milestone,” mentioned Walsh (GRS’09,’12). “There has been so much excitement leading up to this moment. The LEXI operations room exploded with high fives and hugs when we touched down. But a few moments later, it was some collective deep breaths to settle the heart rates and refocus back on the larger mission.”

The Blue Ghost Mission 1 spacecraft, constructed by the personal firm Firefly Aerospace and commissioned by NASA, had touched down efficiently—a history-making touchdown for BU and for Firefly. The connected telescope, known as the Lunar Environment heliospheric X-ray Imager (or LEXI) is the primary machine created by the University to land on one other planetary physique. It was additionally the primary moon operation for Firefly, which turned the first business firm to efficiently land on the moon.

Rousseau Nutter (ENG’20), a mechanical engineer at NASA Goddard Space Flight Center who returned to BU to assist handle the challenge, was within the room when LEXI landed. “All right. Let’s get to work,” he mentioned after the temporary celebration. “We’re on the moon.” 

Six hours later, LEXI powered up and opened its protecting mud cowl, exposing the imager’s lenses to the huge expanse of area.

From Lab to Lunar Landing

Getting LEXI from the lab to the moon took six years of researching, designing, engineering, and testing to ensure the 24-pound imager might stand up to the depth of spaceflight, deal with drastic temperature swings, and talk seamlessly to the ENG-based management room.

In March 2024, Walsh and his group transported the instrument by truck to Firefly Aerospace’s headquarters in Austin, Tex., the place it was mounted on and built-in into the Blue Ghost lander. The LEXI group—amongst them Nutter, Emil Atz (ENG’23,’23), Cat Paw U (ENG’23,’24), Van Naldoza (ENG’20,’25,’26), Cadin Connor (CAS’20, ENG’22,’29), Anika Dujakovich (ENG’25,’27), analysis scientist Ramiz A. Qudsi, and Carl Schmidt (GRS’08,’13), a College of Arts & Sciences analysis assistant professor of astronomy—continued to attach and check LEXI via the lander’s laptop techniques.

And then, on January 15, 2025, Blue Ghost blasted off from the Kennedy Space Center in Florida, using on a SpaceX Falcon 9 rocket. The spacecraft orbited Earth for 25 days, transited between Earth and the moon for 4 days, then went into lunar orbit for 16 days earlier than touchdown on the moon. 

LEXI’s aim was to get an unprecedented view of Earth’s magnetosphere, the magnetic bubble that shields us from charged particles and photo voltaic radiation. Specifically, Walsh says, the instrument was designed to picture, for the primary time, the boundary of Earth’s magnetic discipline, known as the magnetopause, and the best way it deflects the fixed circulation of photo voltaic wind and high-speed charged particles emanating from the solar.

If you’ve ever seen the dazzling colours of the aurora borealis, you then’ve witnessed Earth’s magnetic discipline interacting with photo voltaic wind, making a geomagnetic storm. The intention of LEXI was to view that phenomena from the other perspective: as a substitute of trying up from Earth’s floor, it appeared again at Earth from the vantage level of the moon. Once interpreted, LEXI’s information might help illuminate the magnetic relationship between Earth and the solar that has allowed life on Earth to exist.

Once the telescope touched down, the BU group didn’t have a second to waste. They had solely 10 days to report information earlier than the setting solar plunged the moon into frigid darkness—with temperatures dipping as little as -208 levels Fahrenheit and freezing Blue Ghost’s electrical parts. All of the info needed to be monitored in almost actual time to make sure it was recording as anticipated, in accordance with Qudsi, a BU Center for Space Physics analysis scientist and lead information scientist and software program developer for LEXI. 

“I am most excited about seeing the fluctuations in the Earth’s magnetopause that we will be able to measure using LEXI data,” Qudsi says. “This hasn’t been done yet and LEXI provides a wonderful opportunity to do so.”

Unlike the telescope we use to identify stars and planets, LEXI records individual photons that consequence from a phenomenon known as the photo voltaic wind charge-exchange, which is when charged atoms emitted from the solar slam into impartial particles, like hydrogen, in Earth’s outer ambiance. The charged atom then steals an electron from the hydrogen. That alternate releases an X-ray within the course of. Those invisible wavelengths of sunshine, consistently current round our planet, can point out how a lot photo voltaic wind is pushing up towards Earth’s magnetic power discipline. When quite a lot of vitality breaks via, geomagnetic storms type.

LEXI recorded these faint X-rays with particular optical lenses—a design impressed by lobsters’ eyes, which may see in darkish, murky environments—that decide up the faintest glowing indicators. The BU group collaborated with researchers from NASA’s Goddard Space Flight Center, Johns Hopkins University, University of Miami, and the University of Leicester within the United Kingdom to develop LEXI’s lenses and equipment. 

The week that LEXI was amassing information was a tiresome stretch. Each group member rotated out and in of the management room in eight-hour shifts so the knowledge could possibly be monitored 24 hours a day. 

“It was a very intense week,” says Walsh, who first started measuring X-ray indicators within the ambiance as a postdoctoral researcher at Goddard. There had been some challenges whereas LEXI was on the moon, together with higher- and lower-than-anticipated temperatures. But the Blue Ghost and LEXI stayed the course. Nutter, who dealt with the group’s schedule, says everybody executed the plan flawlessly. “We have a fabulous team that made it extremely easy to manage the schedule,” he says.

In complete, LEXI operated for greater than 150 hours on the lunar floor, accumulating a trove of helpful information. Toward the tip of the mission, on March 14, Blue Ghost witnessed a complete photo voltaic eclipse, when the Earth blocked the solar; a few days later, LEXI recorded the solar set on the moon. “We saw some really interesting things about how the surface of the moon changes as the sun sets, and got some really good data,” Walsh says. 

By 5:19 pm EST on March 16, about 5 hours after sundown, LEXI shut down for the ultimate time. And by 7:10 pm, a number of hours into the lunar night time, Blue Ghost’s batteries reached zero, as anticipated, making it inconceivable for the devices to show again on. The lander will stand powerless, with LEXI pointing as much as the sky, for the foreseeable future, shining within the windless panorama of the moon. 

The Next Phase

Now, the LEXI group is tasked with analyzing hours of photos recorded from the lunar floor and portray an image of Earth’s magnetic discipline boundary.

The information might help reply some large questions, corresponding to predicting when and the way Earth receives excessive quantities of vitality from the solar that trigger geomagnetic storms. “We live in this bubble, this magnetosphere,” Walsh explains. “Some days, a lot of energy breaks into that magnetic bubble. We’re trying to understand how that process works.”

It’s unclear if these high-energy days are a results of modifications within the photo voltaic wind, or if vitality is increase after which penetrating the magnetosphere in a single large burst, or if vitality is getting absorbed regularly into the magnetosphere like a continuing stream of wind. This is essential to know. During large geomagnetic storms, satellites should be raised of their orbits, as a result of the decrease ambiance turns into dense from elevated warmth and vitality that drag satellites down. Storms also can end in disturbances to radio communications, navigation expertise, and aerospace techniques. 

Walsh hopes LEXI’s information might help inform fashions that predict these days of maximum area climate.

“I’m proud of everything the team has done, through development, launch, flight, and surface operations,” he says. “We’ve just begun to work through the science data but have already started to discover new things about the lunar surface and our local space environment. Looking back, the team is proud to have left a set of paw prints in the lunar regolith as the first Terrier on the moon.”
