ISRO and NASA Successfully Launch $1.3 Billion NISAR Satellite to Monitor Earth's Changes
- NISAR, a joint ISRO-NASA mission, lifted off today on the GSLV-F16 rocket from Sriharikota.
- The $1.3 billion satellite is the world's most advanced Earth observation mission, equipped with dual-band radar.
- NISAR will scan the globe every 12 days, tracking land, ice, forest, water, and disaster-prone zones.
- It can detect surface changes as small as 1cm, aiding in climate research, disaster prediction, and resource management.
- The mission marks the strongest India-US space partnership, with all data to be shared globally with scientists.
Apple iPhone 17 Series Unveiled: Thinnest Air, 120Hz Display, and All-48MP Cameras
- Apple launched the iPhone 17 series with four models, including the thinnest-ever iPhone Air at 5.6mm thickness with a titanium frame.
- The base iPhone 17 now features a larger 6.3-inch 120Hz ProMotion display, previously exclusive to Pro models.
- All models, including Air and Pro versions, come with advanced 48MP Fusion cameras; Pro models have triple 48MP cameras with up to 8x optical zoom.
- The iPhone Air is slim and light, powered by the A19 Pro chip, with a 6.5-inch ProMotion display and 3000 nits peak brightness.
- Pre-orders begin September 12, with availability from September 19, starting storage at 256GB and multiple color options.
ISRO Engineers' Vigilance Prevented Fatal Oxygen Leak in SpaceX Rocket, Says Shubhanshu Shukla
- Indian astronaut Shubhanshu Shukla praised ISRO engineers for detecting a liquid oxygen leak in Falcon-9 rocket.
- ISRO's insistence led to thorough checks revealing a critical crack in oxidiser line before Axiom-4 mission.
- SpaceX initially underestimated the leak, risking catastrophic failure without ISRO intervention.
- The leak detection delayed the launch but ensured safety, saving lives of four astronauts.
- Shukla highlighted cooperation, continuous briefings, and responsibility among ISRO, NASA, and SpaceX teams.
Australian Scientists Grow World’s First Fully Functioning Human Skin in Laboratory
- Scientists at University of Queensland created the world’s first lab-grown human skin with blood vessels.
- The skin model includes hair follicles, nerves, immune cells, and tissue layers mimicking natural skin.
- It took six years to develop using stem cells reprogrammed from human skin cells.
- This breakthrough aids better treatment for burns, grafts, inflammatory, and genetic skin diseases.
- The lab-grown skin enables accurate disease study, safer drug testing, and future regenerative therapies.
Scientists See Insides of Dying Star for the First Time, Unlocking Stellar Secrets
- Astronomers observed supernova 2021yfj, revealing a star's silicon- and sulfur-rich inner layers.
- The dying star had lost nearly all outer layers, exposing deep inner shells before exploding.
- This rare event offers new insight into heavy element formation inside massive stars.
- Star stripping to its oxygen-silicon core suggests a new type of supernova explosion.
- The findings challenge current understanding of how massive stars shed material late in life.
Covid May Age Women's Blood Vessels By 5 Years, Raising Heart Risks: Study
- Covid-19 can accelerate blood vessel ageing by about five years, especially in women.
- Women with persistent long Covid symptoms show greater artery stiffness than men or non-infected.
- The study spanned 2,400 participants across 16 countries, measuring blood vessel stiffness over a year.
- Increased artery stiffness heightens risks of heart disease, stroke, and heart attacks in affected women.
- Vaccinated people post-Covid had less stiff arteries than unvaccinated; effects stabilised after a year.
