NASA/Loral O’Hara The Choctaw Heirloom Seeds investigation flew five varieties of heirloom seeds from the Choctaw Nation of Oklahoma aboard the International Space Station in early November 2023. The seeds are Isito (Choctaw Sweet Potato Squash), Tobi (Smith Peas), Tanchi Tohbi (Flour Corn), Tvnishi (Lambsquarter), and Chukfi Peas. The seeds spent six months aboard station, returning to Earth in April 2024.
Next spring, Jones Academy students will plant the space-flown seeds alongside Earth-bound seeds of the same type in the school’s Growing Hope Garden. Students will hypothesize how the seeds will grow and make observations throughout the growing season.
Middle school teachers are developing curriculum incorporating the seeds’ journey to space station and students’ experiments in the garden. This research could impact Native and Indigenous populations across the United States, inviting underrepresented groups to engage with science, technology, engineering, and mathematics.

NASA/Matthew Dominick NASA astronaut Matthew Dominick captured this timelapse photo of Comet C/2023 A3 (Tsuchinshan-ATLAS) International Space Station as it orbited 272 miles above the South Pacific Ocean southeast of New Zealand just before sunrise on Sept. 28, 2024. At the time, the comet was about 44 million miles away from Earth.
Though the comet is very old, it was just discovered in 2023, when it approached the inner solar system on its highly elliptical orbit for the first time in documented human history. Beginning in mid-October 2024, Comet C/2023 A3 (Tsuchinshan-ATLAS) will become visible low in the west following sunset. If the comet’s tail is well-illuminated by sunlight, it could be visible to the unaided eye. Oct. 14-24 is the best time to observe, using binoculars or a small telescope.
The comet hails from the Oort Cloud, which scientists think is a giant spherical shell surrounding our solar system. It is like a big, thick-walled bubble made of icy pieces of space debris the sizes of mountains and sometimes larger. The Oort Cloud lies far beyond Pluto and the most distant edges of the Kuiper Belt and may contain billions, or even trillions, of objects.

8 Min Read Kathryn Sullivan: The First American Woman to Walk in Space
Astronaut Kathryn D. Sullivan checks the latch of the SIR-B antenna in the space shuttle Challenger's open cargo bay during her historic extravehicular activity (EVA) on Oct. 11, 1984. Earlier, America's first woman to perform an EVA and astronaut David C. Leestma, participated in an in-space simulation of refueling a spacecraft in orbit. Credits: NASA Forty years ago, in October 1984, Kathryn D. Sullivan became the first American woman to walk in space. But being the first presented several challenges that started well before she took those historic steps. Things got complicated just after she learned of her assignment.
Questions of Physiology
Biomedical researchers at NASA’s Johnson Space Center (JSC) raised what they believed was a serious issue with women walking in space and alerted George W.S. Abbey, the head of the Flight Crew Operations Directorate. Females, he learned, were more likely than their male counterparts to develop the bends in the low-pressure environment of the extravehicular mobility unit (EMU), the spacesuit she would wear. To alleviate the possibility of developing decompression syndrome, all spacewalkers had to breathe pure oxygen before a spacewalk to eliminate nitrogen from their bloodstream. Researchers insisted Sullivan (and any future women spacewalkers) spend more time than their male counterparts breathing pure oxygen before going outside of the space shuttle. Sullivan quickly learned that there were flaws in the research, which she countered, and Abbey ended up approving the same requirements for men and women doing an extravehicular activity (EVA).
Setting the Record
After the STS-41G crew had been named in the fall of 1983, a colleague—flush with excitement over the recent flight announcement — congratulated Sally K. Ride and Sullivan on their new titles: Ride being the first woman to fly in space twice and Sullivan the first woman to walk in space. Both shook their heads and explained that it would be many months before launch and that a Soviet woman would fly and do a spacewalk well before the space shuttle Challenger and her crew made it to orbit. As expected, the Soviets assigned cosmonaut Svetlana Y. Savitskaya to a second mission in 1983, less than a month after NASA’s crew announcement. In July 1984, Savitskaya, not Ride, went on to become the first woman to enter space twice and earned the distinction of being the first female to walk in space.
Astronauts Sally K. Ride (right) and Kathryn D. Sullivan, two of three mission specialists, synchronize their watches prior to ingressing the Space Shuttle Challenger on the launch pad at Kennedy Space Center on October 5, 1984.NASA Sullivan was not disappointed at losing the title. As she recalled in an oral history interview, being selected for an EVA was an “extraordinary opportunity,” and it did not matter where she was in the queue. She could not understand how people arrived at the idea that the “seventh, tenth, or thirteenth … is [any] less meaningful … than some historical first.”
Others at the Johnson Space Center still thought there was a way they could best the Soviets. Sullivan’s trainers took note of how short Savitskaya’s EVA was. It was only about three and a half hours. “A little bit more than that,” they explained, and “you’ll get the duration record!” But the idea of breaking her record by a few minutes seemed ludicrous. “I’m certainly not going to go tromping around on dinner speeches … saying, ‘Well yes, but I have the duration record.’”
“Hello, I’m right here!”
While the issue of breaking and setting records remained of interest at NASA more than twenty years after the Soviets sent cosmonaut Yuri Gagarin into space, Sullivan found herself grappling with other matters she found equally frustrating. First, there was the sexist media. No journalist asked how she was feeling about her role in the mission. Flying women in space was still new to the American news media in 1983—Ride had only flown her first mission in June, and while Judith A. Resnik had been named to a mission, she had not yet been in orbit. But Ride had not completed an EVA; only men had walked in space, and some found the activity challenging. Astronaut Eugene A. Cernan described his first EVA as the “spacewalk from hell.” Spacewalks can be physically demanding, and it was assumed that women might not have the strength to do so. Reporters asked commander Robert L. Crippen and Ride, “Do you think Kathy can do this?” Sitting at the preflight press conference she reminded reporters that she could speak for herself. “Hello, I’m right here! Hello. Hello.”
The crew assigned to the STS-41G mission included (seated left to right) Jon A. McBride, pilot; mission specialists Sally K. Ride, Kathryn D. Sullivan, and David C. Leestma. Standing in the rear, left to right, are payload specialist Paul D. Scully-Power, mission commander Robert Crippen, and payload specialist Marc Garneau. Launched aboard the Space Shuttle Challenger on October 5, 1984, the STS-41G mission marked the first flight to include two women.NASA There was also the matter of why her spacewalking partner, David C. Leestma, led the EVA. She had two years seniority in the Astronaut Office, arriving in 1978; NASA named Leestma to the corps in 1980. She also worked on spacesuit issues and the mission’s payload longer than he had, but both were rookies on this mission. Sullivan did not think Crippen and Abbey thought she was incapable, but for traditional norms to have been breached in this instance she could not explain why she—the senior ranking astronaut—was playing a support role instead of leading. If anyone asked why, Sullivan told Crippen he—not she—would have to answer the tough questions.
Space Suit Fit
As she prepared for the flight, she began training in the shuttle EMU, which never quite fit her body. The suit’s elbow did not align with hers so when she bent her arm, she had to use extra force. The lower portion of the suit was misaligned, making it difficult to bend her knee. Being the first American woman to do a spacewalk, she decided what was most important was to perform the EVA and demonstrate the EMU worked for women. “I reckoned the wrong thing to do was to turn the first evolution of a woman doing a spacewalk into a controversy. … I just sucked it up and dealt with it.” The suit techs knew the EMU was not quite her size, but she made it work. Later, when assigned to STS-45, one of the techs noticed how poorly the suit fit. “We ought to do something about it. It ought to fit you,” he said. Sullivan responded, “We can start that conversation now, but if you think I was going to make that the conversation on the first EVA you’re crazy.”
Astronaut Kathryn D. Sullivan, STS-41G mission specialist, gets some help with her extravehicular mobility unit (EMU) prior to participating in an underwater simulation of an extravehicular activity (EVA) scheduled for her flight aboard the Columbia in October 1984. Dr. Sullivan and David C. Leestma (out of frame) participated in the rehearsal in NASA’s weightless environment training facility (WET-F) at the Johnson Space Center.NASA A Walk to Remember
Two days after Sullivan’s thirty-third birthday, STS-41G launched on October 5, 1984. Once in orbit, the flight plan changed quickly. A problem with a malfunctioning Ku-band antenna meant that the EVA had to be pushed back to the day before reentry. Sullivan worried that the walk might be scrapped, but when they finally began the pre-breathing protocol, she relaxed. “Challenger, Houston: You are GO for EVA,” Sullivan recalled, “were the sweetest words I had ever heard.” Sullivan and Leestma’s EVA was short—only three hours and twenty-nine minutes—but busy. Leestma demonstrated it was possible to refuel satellites in orbit, while Sullivan monitored his work. When he wrapped up his task, Sullivan finally had the opportunity to “do something, not just watch things.” She stowed the malfunctioning antenna and before they went back inside the shuttle, they filmed a scene for an IMAX film, The Dream is Alive—where the two spacewalkers rose from the bottom of the space shuttle’s windows and waved at the crew inside, mimicking the “Kilroy Was Here” meme. When filming concluded, Sullivan and Leestma returned to Challenger. “My first spacewalking adventure,” Sullivan wrote in her memoir, “was over all too soon.” The next day, President Ronald Reagan called to ask Sullivan about her experience. “Kathy, when we met at the White House, I know you were excited about walking in space. Was it what you expected?” he asked. Sullivan responded affirmatively and added, “I think it was the most fantastic experience of my life.”
I think it was the most fantastic experience of my life.

When she returned to JSC she learned that the EVA flight team had tried to figure out how to send her a diplomatic message to stay outside longer to beat Savitskaya’s record. There ended up being a “five-or six-minute difference” between Sullivan and Savitskaya, “and in the wrong direction as far as they were concerned.”
Despite all the challenges she faced as the first American woman to walk in space, Sullivan called the EVA “a fabulously cool experience.” She hoped to do another, but she never received another assignment to walk in space. She recognized what a unique opportunity she had—very few people have flown in space, and even fewer “get to sneak outside. I’m not going to diminish one dose of sneaking outside just because I didn’t get two, three, or four.”

The world is full of mysterious places, and Vottovaara Mountain in Russia's Republic of Karelia is one of them. This site has been revered for thousands of years by ancient Saami tribes and shamans, who considered it a sacred place surrounded with powerful energy.
Image credit: Universe Inside You
Vottovaara is home to numerous strange megalithic structures and ruins that many believe couldn't have formed naturally. Among these are around 1,600 sacred stones, known as "seids," arranged in a puzzling pattern. These stones, often unusually shaped, are precariously balanced on small rocks in ways that defy simple explanations. While scientists suggest that this was the result of natural processes during the Ice Age, the sheer number and precision of these balanced stones challenge the idea that they occurred by chance.
Another intriguing feature of Vottovaara is a structure referred to as "the well," which locals believe to be an ancient, man-made water reservoir.
As you climb Vottovaara, you'll notice an eerie transformation in the trees. None of the trees on the summit are older than a few decades, and while young pines and firs start growing normally, they soon begin to twist and deform in bizarre ways. This phenomenon is thought to be caused by some unknown energy affecting the trees.
Known as Death Mountain, Vottovaara also is believed to be connected to ancient spirits that are said to inhabit the area, adding to its aura of mystery.

Mount Kailash is a mountain in Ngari Prefecture, Tibet Autonomous Region of China. It lies in the Kailash Range of the Transhimalaya, in the western part of the Tibetan Plateau. The peak of Mount Kailash is located at an elevation of 6,638 m, near the trijunction between China, India and Nepal.
In Tibetan Buddhism, Mount Kailash holds a special place as the Axis Mundi, or the center of the universe. Imagine it as the heart of everything, where heaven and earth meet. This sacred mountain isn't just a random peak; it's like the cosmic hub, connecting different realms together.
In the year 1999, an expedition of Russian Scientists led by Dr Ernst Muldashev claimed that Mount Kailash is too perfectly shaped for a natural mountain. They have discovered that the top of Mt. Kailash is actually a man-made vacuum pyramid. It is surrounded by more than 100 other small pyramids. According to preliminary estimates, the direct height of the pyramid complex is between 100 and 1,800 meters, while the Egyptian pyramid is only 146 meters
It is also believed to be the site of Lord Shiva, the god of destruction and rebirth as well as where the first human beings were created.
According to the legend Shiva has left a giant footprint on the summit of the mountain. Despite extensive searches, no concrete evidence of this footprint has ever been found.
While exploring Mount Kailash on Google Earth, I spotted a large, unusual anomaly near the summit. It resembles two hands, each with four visible fingers, positioned opposite each other and seemingly carved into the rock.
Could these huge hands be a kind of a 'footprint' of Shiva that people have been searching for?
As for climbing up the summit, some daring mountaineers have attempted to do so, but with no luck. It also is said that who climb Mount Kailash age quickly. The time that human takes to age two weeks only take 12 hours in the mountain. Numerous hikers have detailed that they feel like their nails and hairs are developing rapidly within 12 hours.
Trekking all the way up to the peak of Mount Kailash is held to be a forbidden act among Hindus for the fear of trespassing the sanctity of the mountain and disturbing the divine energies residing there.
Even planes don't fly over Kailash as Mount Kailash is said to possess a mysterious magnetic anomaly that disrupts navigational instruments and disrupts compass readings. This phenomenon has puzzled scientists with no concrete explanation offered to date.
Coordinates: 31° 4'4.83"N 81°18'24.47"E
Mount Kailash is still a mystery. The unconquered peak remains wrapped in myths, legends, and spiritual tales.View the full article
