Sandy elementary school becomes steward of NASA moon tree

Sandy elementary school becomes steward of NASA moon tree

Yahoo03-05-2025

Smokey Bear joined students and staff at Sprucewood Elementary School on Tuesday to help plant a unique Artemis I Moon Tree, granted to them by NASA.
The school's new Douglas fir seedling is dubbed a 'moon tree' because it was grown from a seed carried aboard NASA's Orion spacecraft when it circumnavigated the moon in November 2022, traveling over 270,000 miles in its journey from Earth and back.
The seeds for five tree species were aboard the unmanned spacecraft for the Artemis I mission. The U.S. Department of Agriculture Forest Service grew the seedlings before distributing them to approved tree stewards.
School librarian Sara Lee first learned about moon tree stewardship after reading 'Moon Tree: The Story of One Extraordinary Tree' by Carolyn Bennett Fraiser. Lee explained that Frasier contacted her to let her know about the book in August 2022 because a moon tree was located near the school in Draper. She then found out NASA was introducing a new generation of moon trees as part of its national STEM engagement and conservation education initiative, so she applied for her school to be considered.
After waiting two years to hear back about the application, Lee was surprised to find out the school had been selected to be a steward out of more than 1,300 applications.
'I was blown away when I got the first email saying that we had tentatively been chosen,' Lee said. 'Then, when we got back (from spring break), there was an email that said, 'Congratulations, moon tree steward, show us your celebrations.' ... We got our welcome packets and then the tree came the next day.'
The school dedicated its moon tree at a celebration on Tuesday, joined by the U.S. Forest Service. Six students acknowledged for demonstrating leadership by following school rules helped Lee, Smokey Bear and teacher-of-the-year recipient Emigh Lo plant the seedling in a patch of grass near the playground.
'I think (the moon tree) is really cool because it traveled around the world and space. I think it's cool we had someone special to share it with,' said Matthew, a fourth-grade student at the school, referring to Smokey.
Unknown to students, however, was that Smokey Bear was being portrayed by Lee's husband, who is a cartographer for the Forest Service and helped coordinate the special appearance.
'We had great support from our local Forest Service office and my administration was awesome. They treated this as the big deal that I was hoping it would be,' said Lee.
Students officially welcomed the tree to their campus by participating in their school's 'happy chant' before ending the celebration. Principal Cathleen Schino also reminded students to take care of the tree, especially while it is still a seedling. The tree will be surrounded by a barrier to protect it from stray balls and toys from the playground and is accompanied by a plaque that explains its status as a moon tree.
'NASA ​and ​the ​Forest Service ​have ​trusted ​us ​to ​take ​care ​of ​this ​tree, ​to ​be ​the ​keepers ​of ​the ​tree, ​to ​care ​for ​it, ​and ​to ​keep ​it ​safe ​and ​healthy,' said Schino, addressing students. '​So ​we're ​going ​to ​make ​sure ​that ​we ​take ​care ​of ​it ​by ​admiring ​it ​with ​our ​eyes ​​instead ​of ​our ​hands. Every ​time ​you ​go ​by ​it, ​we ​know ​that ​plants, ​​they ​grow ​with ​love. ​We've ​been ​practicing ​giving ​compliments ​all ​year ​and ​using ​emotional ​safety, so ​please ​talk ​to ​our ​moon ​tree. ​Give ​it ​positive ​comments. ​It ​really ​is ​a ​thing. It ​will ​grow.'
NASA began the new generation of moon tree stewardship as a nod to the historic Apollo 14 mission, where Stuart Roosa, astronaut and former smokejumper for the U.S. Forest Service, carried hundreds of seeds to space to see if they would still grow after being in a zero-gravity environment. According to Lee, the canister of seeds broke in space, but they were able to save 420 seeds that would later be planted at national monuments in celebration of the U.S. bicentennial.
Four of those trees were initially sent to Utah in the 1970s, but only two are still accounted for. One is a Douglas fir that was planted at the state Capitol but was cut down after being destroyed by a tornado in 1999. The other is a sycamore tree planted at the Lone Peak Conservation Center in Draper that is still standing, but is infected with a fungal disease.
Draper's almost 50-year-old moon tree is now joined by two of the new generation's seedlings — one at Sprucewood Elementary and another at Glacier Hills Elementary, both part of the Canyons School District.
'I feel like it's special,' said Lee. 'Not everybody has a tree grown from a seed that traveled 270,000 miles from space. So I wanted something special, something that even when (students are) older, they'll remember that this happened and it's accessible here. They can bring their parents and, ideally, my kids who helped plant it, (can bring their) kids back some day and show them.'
Lee explained that the area where the tree was planted is also special because it was previously home to another tree planted in memory of a student who died. The tree was later cut down, but now Lee hopes the area will continue to be visited by students and remembered for generations to come.

Asteroids with ‘unstable orbits' hide around Venus—do they threaten Earth?

NASA's Parker Solar Probe captured this image showing the nightside surface of Venus. A family of asteroids share the planet's orbit, and two new studies suggest that one day the space rocks could theoretically pose a danger to Earth. Photograph by NASA/APL/NRL Venus has groupies—a family of asteroids that share its orbit, either trailing it or leading it as the planet revolves around the sun. Researchers have known that such stealthy space rocks might exist for years, but now, a pair of papers (one published in a journal, and one a pre-print undergoing peer-review) conclude that some might develop unstable orbits and, over a very long period of time, arch toward Earth. But despite what several histrionic headlines have claimed, Earth is not at risk of one of these asteroids suddenly sneaking up on us and vaporizing a city. While some of these asteroids could be large enough to cause this sort of damage, there is no evidence whatsoever suggesting any of these Venus-pursuing asteroids are currently heading our way. 'I wouldn't say that these objects are not dangerous,' says Valerio Carruba, an asteroid dynamicist at the São Paulo State University in Brazil and a co-author of both studies. 'But I don't think there is any reason to panic.' These studies simply highlight that asteroids near Venus have the potential to fly our way on sometime in the next few thousand years or so. 'The likelihood of one colliding with Earth any time soon is extremely low,' says Scott Sheppard, an astronomer at the Carnegie Institution for Science in Washington, D.C. who was not involved with the new research. 'There isn't too much to be worried about here.' Asteroids around Venus, shown in the background above during a 2012 transit, are difficult to track because they fall inside Earth's orbit and are obscured by the sun's glare. Research suggests that some of the asteroids that share Venus' orbit are large enough to take out a city on Earth. Illustration by David A. Hardy, Futures: 50 Years In Space/Science Photo Library The real problem, though, is that asteroids like this are remarkably difficult to find, and you can't protect yourself against a danger you cannot see. Fortunately, in the next few years, two of the most advanced observatories ever built are coming online. And together, they will find more asteroids—including those hiding near Venus—than the sum total already identified by the world's telescopes. Concealed by sunlight While the Japanese and European space agencies mostly request time on busy telescopes to search for these space rocks, NASA leads the pack: It funds a network of observatories solely dedicated to finding sketchy-looking asteroids. Planetary defenders are chiefly concerned about near-Earth asteroids. As the name suggests, these have orbits that hew close to Earth's own. Many of these asteroids were removed from the largely stable belt between Mars and Jupiter, either through the chaotic gravitational pull of the planets (often Jupiter, as it's the most massive) or through asteroid-on-asteroid collisions. If one gets within 4.6 million miles of Earth's orbit, there's a chance that, over time, both orbits cross and a collision becomes possible. And if that asteroid is 460 feet long, it's big enough to plunge through the atmosphere and (with a direct hit) destroy a city. Combined, these characteristics describe 'potentially hazardous asteroids'—and finding them is of paramount importance. Venus appears above giant sandstone cliffs amid the sand dunes of Tassili National Park in Algeria. Photograph by Babak Tafreshi, Nat Geo Image Collection Asteroids are first found because of the sunlight they reflect. That works well for most, but there are known to be asteroids hiding interior to Earth's orbit, toward the direction of the sun. And that's a problem. Astronomers seeking out these asteroids cannot just point their telescopes directly at the sun: It would be like trying to see a lit match in front of a nuclear explosion. Instead, they look in the vicinity of the sun in the few minutes just after sunset, or just before sunrise. Not only are these surveys severely time-limited, but by aiming close to the horizon, they are peering through more of the Earth's atmosphere, which distorts what they are looking at. 'All of these factors make it hard to search for and discover asteroids near Venus' orbit,' says Sheppard. (Here's how researchers track asteroids that might hit Earth.) The invisible Venusian fleet Asteroids have occasionally been spotted in this sun-bleached corner of space. And twenty of them have been found scooting along the same orbital highway Venus uses to orbit the sun. These are known as co-orbital asteroids; similar rocks can be found either following or trailing other planets, most notably Jupiter. Co-orbiting asteroids tend to cluster around several gravitationally stable sections, known as Lagrange points, along the planet's orbital path. But over a timescale of about 12,000 years or so, it's thought that the Venus co-orbital asteroids can dramatically alter their orbits. They remain on the same orbital path as Venus, but instead of maintaining a circular orbit, they get creative: Some migrate to a different Lagrange point, while others zip about in a horseshoe pattern around several Lagrange points. Some of these new, exotic orbits become quite stretched-out and elliptical—and, in some cases, these orbits can eventually bring these asteroids closer to Earth. When they do, 'there is a higher chance of a collision,' says Carruba. In their first study, published in the journal Icarus earlier this year, Carruba and his team looked at the 20 known co-orbital asteroids of Venus. Their simulations forecast how their orbits would evolve over time and show that three of the space rocks—each between 1,000 and 1,300 feet or so—could approach within 46,500 miles of Earth's orbit. (For reference, the moon is an average of 240,000 miles from our planet.) That proximity may make them potentially hazardous asteroids. But there's no need to worry—it can take as long as 12,000 years for an asteroid to end up on an elliptical, near-Earth orbit. Perhaps they will be a problem for our very, very distant descendants. The asteroids that hang out in the orbit of Venus (shown above in simulated color) are largely unknown. This illustration shows the orbits of the binary near-Earth asteroid Didymos (labelled) and another 2,200 potentially hazardous asteroids (fainter lines) around the sun. Illustration by NASA/JPL-Caltech/Science Photo Library The team's latest study, uploaded to the pre-print server arXiv last month, delves into how easy it might be for any of Venus' co-orbital asteroids—including those astronomers have yet to find—to end up on these precarious orbits. To find out, they created virtual asteroids and simulated their many potential orbital voyages 36,000 years into the future. Many things could perturb the orbits of asteroids over that many years, so any truly accurate predictions are impossible. But the simulations came to some broad conclusions. The first is that a Venus co-orbital asteroid is more likely to approach Earth if it switches from a circular to a considerably elongated orbit—it's zooming over a larger patch of the inner solar system, including our own planet's neighborhood. The second, more surprising thing, is that some asteroids still manage to reach near-Earth space even they start out with only a mildly stretched-out orbit. It seems that their chaotic journeys through space, filled with gravitational disturbances, can still end up throwing them our way. But to be clear, these potentially worrisome orbits develop over the course of many millennia. 'This is not something to be alarmed about, as these asteroids are still relatively dynamically stable on human timescales,' says Sheppard. (These five asteroids pose the highest risk to Earth.) A new asteroid-hunting dawn For Marco Fenucci, a near-Earth object dynamicist at the European Space Agency, the paper raises awareness about these relatively mysterious asteroids in Venus' orbit. And that is a good point to make, he adds: We don't know much about these asteroids, including their population size, their dimensions, and their orbits, because we struggle to find them with today's telescopes. Two upcoming facilities are about to make this task considerably easier. The first, the U.S.-owned Vera C. Rubin Observatory in Chile is set to officially come online in the next few weeks. With a huge field-of-view, it can see huge swathes of the night sky at once, and its giant nest of mirrors can gather so much starlight than even the smallest, faintest objects can be seen. In just three to six months, the observatory could find as many as a million new asteroids, effectively doubling the current total. Meg Schwamb, a planetary scientist at Queen's University Belfast who was not involved with the new research, explains that Rubin will also conduct its own twilight surveys, the very sort used today to search for near-Venus asteroids. If these surveys are conducted over the next decade, 'Rubin could find as many as 40 to 50 percent of all objects larger than about [1,150 feet] in the interior-to-Venus-orbit population,' says Mario Jurić, an astronomer at the University of Washington and who was not involved with the new research. But, as with all ground-based optical telescopes, Rubin will still have the sun's glare, and Earth's atmosphere, to contend with. As long as the federal government decides to continue to fund the mission—something that is not guaranteed—NASA will also launch a dedicated asteroid-hunting space observatory, the Near-Earth Object (NEO) Surveyor, in the next few years. Unobstructed by Earth's atmosphere, it will seek out space rocks by viewing them through a highly-sensitive infrared scope, meaning it can see those hidden by the luminous sun. Even those asteroids sneaking around near Venus won't be able to hide from NEO Surveyor. And, finally, says Carruba, 'we can see if the impact threat is real, or not.'

NASA Tracking Three Asteroids Approaching Earth

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. NASA is monitoring three asteroids soaring past the Earth at about 8,000 to 15,000 miles per hour, the biggest of which measures around 1,300 feet in diameter. The largest space rock, known as "424482 (2008 DG5)," is due to zip past our planet at over 13,800 miles per hour later today. It is expected to come as close as 2.17 million miles from the Earth, according to NASA's Jet Propulsion Laboratory (JPL), A smaller asteroid known as "2025 LD," which is around 73 feet in diameter, zoomed past the Earth earlier today at over 15,000 miles per hour, according to the JPL's Center for Near-Earth Object Studies (CNEOS). The space rock came as close as 696,000 miles from the Earth. A third asteroid, known as "2025 KY4," measuring around 42 feet in diameter, also zipped past the Earth earlier today, reaching within 1.72 million miles of our planet. The asteroid soared past at over 8,000 miles per hour. Stock image: An illustration of asteroids floating around in space. Stock image: An illustration of asteroids floating around in space. Getty Asteroids—small, rocky masses left over from the formation of the solar system nearly 4.6 billion years ago—are found in the main asteroid belt, orbiting around the sun between the paths of Mars and Jupiter. In February, data from the CNEOS showed the impact probability of an asteroid known as "2024 YR4" in 2032 was at 3.1 percent. This was "the highest impact probability NASA has ever recorded for an object of this size or larger," the national space agency noted at the time. Further studies that month brought 2024 YR4's chance of Earth impact on December 22 in 2032 down to 0.004 percent. The data showed there is "no significant potential" for 2024 YR4 to "impact our planet for the next century" and "the range of possible locations the asteroid could be on Dec. 22, 2032, has moved farther away from the Earth," NASA said in a blog post on February 24. 2024 YR4 was measured to be about 200 feet across by NASA's James Webb Space Telescope, Andy Rivkin, an astronomer at the Johns Hopkins University Applied Physics Laboratory, noted in a NASA blog post on April 2. There is still a "very small chance," however, for 2024 YR4 to impact the moon on that date, and that probability is currently 1.7 percent, the space agency noted. The orbits of asteroids bring them within 120 million miles of the sun. Most near-Earth objects (NEOs) are asteroids that range in size from about 10 feet to nearly 25 miles across. "The majority of near-Earth objects have orbits that don't bring them very close to Earth, and therefore pose no risk of impact," NASA says. A small portion of NEOs—known as potentially hazardous asteroids—do merit closer attention. PHAs, which are around 460 feet in diameter, have orbits that bring them as close as 4.6 million miles of the Earth's orbit around the sun, NASA notes. Despite the number of PHAs in our solar system, none is likely to hit our planet any time soon. "The 'potentially hazardous' designation simply means over many centuries and millennia the asteroid's orbit may evolve into one that has a chance of impacting Earth. We do not assess these long-term, many-century possibilities of impact," Paul Chodas, manager of the CNEOS, previously told Newsweek.

Japan's ispace tries lunar touchdown again with Resilience lander

By Kantaro Komiya TOKYO (Reuters) -Japanese company ispace is set to try the lunar touchdown of its uncrewed spacecraft again on Friday two years after its failed inaugural mission, in a bid to become the first company outside the United States to achieve a moon landing. Tokyo-based ispace hopes to join U.S. firms Intuitive Machines and Firefly Aerospace, which have accomplished commercial landings amid an intensifying global race for the moon that includes state-run missions from China and India. Resilience, ispace's second lunar lander, is expected to touch down on Mare Frigoris, a basaltic plain about 900 km (560 miles) from the moon's north pole, at 4:17 a.m. Friday local time (1917 GMT Thursday) following an hour-long descent from lunar orbit, according to the company. In 2023, ispace's first lander crashed into the moon's surface due to inaccurate recognition of its altitude. Software remedies have been implemented, while the hardware design is mostly unchanged in Resilience, the company has said. Resilience carries a four-wheeled rover built by ispace's Luxembourg subsidiary and payloads worth a total of $16 million, including scientific instruments from Japanese firms and a Taiwanese university. If the landing is successful, the 2.3-metre-high lander and the microwave-sized rover will begin 14-day exploration activities until the arrival of a freezing-cold lunar night, including capturing images of regolith, the moon's fine-grained surface material, on a contract with U.S. space agency NASA. Later on Friday, ispace will host a press conference about the outcome of the mission, according to the company. Shares in ispace more than doubled earlier this year on growing investor hopes for the second mission, before calming in recent days. Resilience in January shared a SpaceX rocket launch with Firefly's Blue Ghost lander, which took a faster trajectory to the moon and touched down successfully in March. Intuitive Machines, which last year marked the world's first touchdown of a commercial lunar lander, made its second attempt in March but the lander Athena ended on its side on the lunar surface just as in the first mission. Japan last year became the world's fifth country to achieve a soft lunar landing after the former Soviet Union, the U.S., China and India, when the national Japan Aerospace Exploration Agency (JAXA) achieved the touchdown of its SLIM lander, yet also in a toppled position. Despite President Donald Trump's proposed changes to the U.S. space policy, Japan remains committed to NASA's Artemis moon program, pledging the involvement of Japanese astronauts and technologies for future lunar missions. Including one in 2027 as part of the Artemis program, ispace plans seven more missions in the U.S. and Japan through 2029 to capture increasing demands for lunar transportation.
