Discovery of the Week

NASA's Lucy spacecraft reveals a wobbling, peanut-shaped asteroid — During its flyby of the asteroid Donaldjohanson, NASA's Lucy spacecraft found it to be a tumbling, peanut-shaped body formed from debris that coalesced after a violent collision 155 million years ago. The finding shows that even small asteroids lead surprisingly complex lives, shaped by collisions and internal activity. (NASA News)

Space Missions & Astronomy

• Ariane 6 launches Amazon satellites with upgraded boosters — An Ariane 6 rocket with improved solid rocket motors successfully deployed three dozen Amazon internet satellites on June 17, as the European Space Agency considers increasing the vehicle's launch rate. Significance: High. (SpaceNews)
• NASA races to rescue the falling Swift space telescope — A daring mission launching this month will attempt to capture and boost the orbit of NASA's Swift astrophysics spacecraft, which is slowly falling to Earth, extending its life by years. Significance: High. (Science Magazine News; SpaceNews)
• Chinese university-led mission to study asteroid Apophis — A spacecraft from Tsinghua University will join international efforts to study the asteroid Apophis during its extremely close approach to Earth in 2029, offering a rare chance to examine a potentially hazardous object up close. Significance: High. (SpaceNews)
• Relativity Space plans private Mars orbiter mission — The company announced it will launch a Mars orbiter in 2028 as part of a new initiative to privately develop planetary science missions, marking a shift toward commercial deep-space exploration. Significance: Medium. (SpaceNews)
• Webb image captures every stage of star formation — A new image from the James Webb Space Telescope shows a portion of the Orion Molecular Clouds, revealing stellar embryos, protoplanetary discs, and fully formed young stars in one frame. Significance: Medium. (NASA News)
• Hubble glimpses merging galaxy clusters — The Hubble Space Telescope imaged a cluster called CL0016+1609, which X-ray observations show is actually two galaxy clusters merging along our line of sight. Significance: Low. (NASA News)
• New European space telescope will map galaxies' ghostly halos — The European Space Agency approved a mission to trace the faint streams and halos of stars surrounding galaxies, revealing ancient mergers and the influence of dark matter — the invisible substance that makes up most of the universe's mass. Significance: Medium. (Science Magazine News)
• China conducts four launches in three days — China accelerated its launch pace with multiple missions, though prolonged silence after a Kuaizhou-11 solid rocket liftoff suggested possible issues with the payload. Significance: Low. (SpaceNews)
• Curiosity rover surveys rock "bands" on Mount Sharp — NASA's Curiosity rover continues ascending Mount Sharp on Mars, studying layers of exposed rock with different textures and colors that record the planet's ancient environmental history. Significance: Low. (NASA News)

Life Sciences & Medicine

• Autism and ADHD diagnoses rise due to widening criteria, not overdiagnosis — A study of 140,000 people found that broadening diagnostic definitions explain the sharp increase in autism and ADHD diagnoses, suggesting more people are being correctly identified rather than incorrectly labeled. Significance: High. (New Scientist)
• Sloth's slow-motion lifestyle written in its genome — Scientists found genetic clues in the sloth's DNA that explain its famously sluggish metabolism and low-energy lifestyle, offering insights into how evolution shapes extreme adaptations. Significance: Medium. (Nature News)
• Speedy, spiraling electrical waves may coordinate brain activity — Mouse imaging revealed that rotating waves of electrical activity are built into brain anatomy and help connect far-flung regions, potentially explaining how information flows across the brain. Significance: Medium. (Science Magazine News)
• New NIH security rules for genomic data slow research — Stricter security requirements for human genomic data sets are causing delays and prompting researchers to find workarounds, as data security experts say increased oversight is necessary. Significance: Medium. (Science Magazine News)
• Why the human genome's tangled physicality may confound AI — Biologists argue that our genetic heritage is not a simple blueprint or algorithm but a physically tangled, three-dimensional structure that may resist easy analysis by artificial intelligence. Significance: Medium. (Quanta Magazine)

Physics & Materials

• Amazon and Quera promise useful quantum error correction by 2028 — The companies announced a roadmap to achieve practical quantum error correction — fixing the inherent mistakes in quantum computers — sooner than many expected, alongside demonstrations of "beyond-classical" quantum hardware. Significance: High. (Ars Technica Science)
• Boeing demonstrates quantum networking protocol for space — Boeing successfully tested "high-fidelity entanglement swapping" — a key quantum networking technique — in a compact ground payload, ahead of an on-orbit experiment planned for 2027. Significance: Medium. (SpaceNews)

Climate & Earth Science

• Scientists search for heat-resistant coral reefs — As global warming threatens coral ecosystems worldwide, researchers are identifying "coral strongholds" that can withstand higher temperatures, which may help repopulate more degraded reefs in the future. Significance: High. (Ars Technica Science)
• NASA selects DAPHNE mission to study space weather and Earth's atmosphere — The Dynamic Atmosphere-Ionosphere Explorer mission will investigate how space weather — solar storms and radiation — interacts with Earth's upper atmosphere, improving predictions for impacts on GPS and satellites. Significance: High. (SpaceNews; NASA News)
• NASA awards contracts for commercial satellite data — The agency selected eight new companies to supply commercial satellite data, supplementing NASA's Earth-observing satellites with higher-resolution and more frequent measurements for researchers and decision-makers. Significance: Medium. (NASA News)

Technology-Driven Science

• NASA tests highly autonomous rover in California desert — A prototype rover called ERNEST drove 16 miles across the Colorado Desert with minimal human intervention, advancing robotic autonomy for future Moon and Mars exploration. Significance: Medium. (NASA News)
• Bold satellite rescue mission came together in record time — A high-risk mission to reboost a falling NASA spacecraft was developed in under a year, with one team member calling it "a success already, just from the fact that we're even going to try this." Significance: Medium. (Ars Technica Science)

Upcoming: Launches & Publication Dates

• The Swift reboost mission is set to launch later this month. (SpaceNews)
• Boeing's quantum networking payload is scheduled for launch in 2027. (SpaceNews)
