By Passant Rabie Published April 19, 2025 | Comments (0) | NASA’s Lucy spacecraft’s got its first views of the asteroid Donaldjohanson in February 2025. NASA/Goddard/SwRI/Johns Hopkins APL The Lucy mission is on a 12-year journey to explore a peculiar set of asteroids that lead and follow Jupiter as it orbits the Sun. As it journeys to these Trojan asteroids, the probe is preparing for its second stop at the main belt, approaching a mysterious space rock to practice for the main event. NASA’s Lucy spacecraft will carry out a flyby of the small main belt asteroid Donaldjohanson on April 20 at 1:51 p.m. ET, when it will come within an eerily close distance of 596 miles (960 kilometers) from the target. This is Lucy’s second encounter with an asteroid, but it is far more complicated than its first flyby, with NASA describing it as a “comprehensive dress rehearsal for Lucy’s main mission,” the space agency wrote in a news release. Lucy first laid its robotic eyes on Donaldjohanson in February and has been tracking the asteroid over the past two months to prepare for its flyby. Donaldjohanson, named after the discoverer of the Lucy hominid fossil, is a carbonaceous asteroid that’s approximately 2.5 miles (4 km) wide. The asteroid is a fragment from a collision that took place around 150 million years ago, making it one of the youngest main belt asteroids ever visited by a spacecraft. Although it’s not a Trojan asteroid, it is located in a convenient spot for Lucy to swing by it on its way to the Jovian system. The upcoming flyby will provide the team with an opportunity to test Lucy’s systems and carry out observations using all three of the spacecraft’s science instruments. The spacecraft will orient itself to track the asteroid around 30 minutes before its close approach. During that time, Lucy’s high-gain antenna, which it uses to communicate with ground control, will be turned away from Earth, suspending communication. For the remainder of the flyby, Lucy will be on its own, autonomously rotating using its terminal tracking system to keep Donaldjohanson in view. Lucy will then use its science instruments to conduct observation sequences of the asteroid that are very similar to the one it will perform once it reaches the Trojans. Around 40 seconds before its closest approach to the asteroid, however, Lucy will stop tracking Donaldjohanson to protect its sensitive instruments from intense sunlight. “If you were sitting on the asteroid watching the Lucy spacecraft approaching, you would have to shield your eyes staring at the Sun while waiting for Lucy to emerge from the glare. After Lucy passes the asteroid, the positions will be reversed, so we have to shield the instruments in the same way,” Michael Vincent of Southwest Research Institute (SwRI) in Boulder, Colorado, and encounter phase lead of the mission, said in a statement. “These instruments are designed to photograph objects illuminated by sunlight 25 times dimmer than at Earth, so looking toward the Sun could damage our cameras.” After its closest approach, the spacecraft will reorient its solar arrays back toward the Sun. It will reestablish communication with Earth about an hour after its flyby, hopefully beaming back all the precious data it collected. The team, however, does have to be patient considering how far Lucy is from Earth, so the process will take several days. “One of the weird things to wrap your brain around with these deep space missions is how slow the speed of light is,” Vincent said. “Lucy is 12.5 light minutes away from Earth, meaning it takes that long for any signal we send to reach the spacecraft. Then it takes another 12.5 minutes before we get Lucy’s response telling us we were heard. So, when we command the data playback after closest approach, it takes 25 minutes from when we ask to see the pictures before we get any of them to the ground.” Lucy launched in October 2021, and pulled off a flyby of the tiny main belt asteroid Dinkinesh in November 2023. The mission’s first asteroid encounter was far more rewarding than initially anticipated as the brief rendezvous revealed a binary pair with the discovery of a tiny satellite closely orbiting Dinkinesh. The mission’s primary focus is studying the Trojan asteroids, a group of rocky bodies that lead and follow Jupiter as it orbits the Sun. Lucy will begin its tour of the Trojan asteroids in 2027 by visiting Eurybates and its binary partner Queta, followed by Polymele and its binary partner, Leucus, Orus, and the binary pair Patroclus and Menoetius. “Every asteroid has a different story to tell, and these stories weave together to paint the history of our solar system,” Tom Statler, Lucy mission program scientist at NASA, said in a statement. “The fact that each new asteroid we visit knocks our socks off means we’re only beginning to understand the depth and richness of that history. Telescopic observations are hinting that Donaldjohanson is going to have an interesting story, and I’m fully expecting to be surprised—again.” Daily Newsletter You May Also Like By Isaac Schultz Published April 18, 2025 By Passant Rabie Published April 18, 2025 By Passant Rabie Published April 17, 2025 By Isaac Schultz Published April 16, 2025 By Passant Rabie Published April 16, 2025 By Isaac Schultz Published April 11, 2025

Where river Rhine once served as a thriving trade route, today a remarkable nature reserve has reclaimed the land, restoring a sense of peace and serenity. The ancient river bends carve long sightlines through willow groves, along beaver dams. In the heart of this expansive landscape, some space has been reserved for a modern estate.Save this picture!The clients undertook the ambitious task of transforming a polluted site, into a sanctuary where nature and architecture strengthen each other. Through years of dedicated effort, they have reforested the estate, extending the character of the adjacent Natura 2000 area. This newly created nature reserve is shared with passing hikers and fishermen, who are invited to explore the estate's public areas. It marks the beginning of a new chapter, deeply rooted in tradition and conservacy. Set atop a slightly raised river bed, stands the manor house, anchoring the estate. This family home is designed to bring generations together, offering a retreat from the bustle of the city and an opportunity to immerse in nature. It is a place to celebrate life, surrounded by the serenity of the landscape.Save this picture!Save this picture!The manor comprises three wings, each embracing a distinct aspect of the surrounding landscape. Upon arrival, a winding road leads through an English-style parkland, offering changing glimpses of the house and gradually revealing its striking entrance. On the other two sides, the house meets the rugged beauty of the river bends and former agricultural fields, reinforcing the estate's connection to its natural origins.Save this picture!Save this picture!The landscape design carefully enhances both biodiversity and aesthetic appeal. The estate's scenic layered landscape has been enriched with new pathways, while a neighboring organic farmer grazes his Belted Galloway cattle in the meadows, blending agriculture and ecology seamlessly. At the heart of the estate, the manor aligns with a central axis that spans the property. Steps, verandas, and terraces connect the building to its surroundings, integrating indoor and outdoor spaces. The robust stone base supports a lightweight wooden pavilion on top, creating a harmonious architectural balance. Large glass facades frame uninterrupted panoramic views, ensuring a seamless transition between interior and exterior.Save this picture!The natural color palette of warm reddish-brown wood and locally sourced stone harmonizes perfectly with the environment. The hand-laid stone foundation pays homage to the glacial boulders scattered across the region, a subtle nod to the area's geological heritage. This estate is the result of an intensive collaboration, built on trust and a shared vision. What was once a neglected and polluted site is now a thriving example of what can be achieved when architecture and landscape work in harmony. The manor house, modest yet noble, bridges past and future, serving as a home for generations to come. An iconic new landmark at the heart of nature.Save this picture!

Science is, at its heart, a system for asking questions and seeking answers. Researchers must detect clues amid a cacophony of information. Pharmacist Joseph Lambson is one person with a gift for identifying signals in the noise. When he got a call from a poison control specialist saying that people were overdosing on the drug semaglutide, used to treat obesity and diabetes, he knew what this meant. Pharmaceutical companies were unable to keep up with demand for the drug, which comes in a prefilled injector pen, and people were buying alternative versions that are not as error-proof. Even with the drug no longer in shortage, the dangers persist. Senior writer Meghan Rosen talked with Lambson as part of her investigation into a proliferating online market where patients say they’re willing to take risks to get what they see as a life-altering drug.

Hi all, I want to learn Blender, but I have a pretty specific use case in mind: to make album covers that mostly use very basic shapes and imported text (as SVG files). So I don't really want to get too deep into modeling, and definitely want to focus more on dramatic lighting, materials and textures, glow effects, volumetric fog, just overall very cinematic looking designs. I'm attaching some AI-generated images as examples. And the tutorials don't have to be free, BTW. Thanks! submitted by /u/MDesigner [link] [comments]
