NASA spacecraft gains 3.5 km/s speed from Earth’s gravity assist without major engine burn
On September 28, 2026, Juice, the Jupiter Icy Moons Explorer, accomplished a successful gravity assist flyby of Earth. This maneuver was pivotal in adjusting the spacecraft's trajectory and significantly boosting its speed without the need for extensive engine thrust. Throughout its mission, Juice has strategically employed gravity assists, effectively conserving fuel.
Antarctica’s 2 native flowering plants responded differently to 7 years of warming
Research on King George Island examined how two native Antarctic plants responded to long-term warming. Antarctic hairgrass displayed reduced hydraulic conductivity and photosynthesis compared to those in natural conditions. In contrast, Antarctic pearlwort increased both its hydraulic conductivity and photosynthetic capacity. This study provided insights into contrasting adaptive strategies of these plants under sustained environmental changes. These findings highlight the need to understand species-specific responses to climate change effects.
