The satellites SDX01 and SDX02 completed their mission by re-entering Earth's atmosphere after 21 months. They were launched on December 30, 2024, and achieved significant milestones in autonomous docking and power transfer. During their operation, they demonstrated important capabilities for future missions, including lunar exploration and human spaceflight. Their orbital altitude progressively decreased, leading to their eventual re-entry.from Science News: Fresh Discoveries, Research & Breakthroughs https://ift.tt/MR6FhdP
Researchers utilized drone technology to discover three previously unregistered Aboriginal rock shelters in the Blue Mountains region, revealing significant cultural heritage. Collaboration with the Dharug Custodian Aboriginal Corporation ensured accurate documentation of red hand stencils and stone artifacts. This innovative approach may improve archaeological surveys in difficult-to-navigate areas, thereby preserving cultural heritage. Ongoing efforts will assess the method's applicability to different Australian landscapes, ensuring continued protection.
Archaeologists collaborated with Indigenous rangers to explore submerged sites off Murujuga in Western Australia. They uncovered artefacts and evidence of past human activity before rising sea levels altered the landscape. Two key locations highlighted interactions with freshwater resources and elevated terrains. The research involved several universities and emphasized the importance of Indigenous expertise in cultural heritage.
