Sunita Williams and Butch Wilmore have safely returned to Earth after spending over nine months aboard the International Space Station, their mission extended due to technical problems with Boeing’s Starliner capsule. Both astronauts are currently undergoing intensive rehabilitation to readjust to Earth’s gravity and rebuild muscle strength. They are also contributing to NASA and Boeing’s efforts to improve future space missions.

A new study suggests a massive meteorite impact 3.26 billion years ago, far larger than the dinosaur killer, may have acted as a "giant fertilizer bomb" on early Earth. This impact, releasing vital nutrients like phosphorus and mixing ocean layers, potentially spurred a microbial explosion. The event highlights how catastrophic events could foster biological innovation and diversification in early life.
The Indian Space Research Organisation (ISRO) has announced a recruitment drive for 320 scientists and engineers across various technical departments. Applications are being accepted online until June 16, 2025. The recruitment focuses on filling positions in electronics, mechanical engineering, and computer science, offering opportunities to contribute to India's space missions. The selection process involves a written exam and an interview.
SpaceX's Starlink is poised to launch in India, armed with a Letter of Intent from the Department of Telecommunications. The initial phase targets urban areas with 600-700 Gbps bandwidth, serving 30,000-50,000 customers. Plans may start at $10 per month, offering high-speed internet, especially benefiting underserved regions, with aims to expand to 3 Tbps by 2027.
A recent Virginia Tech study reveals that the Pacific Northwest faces a heightened risk of catastrophic flooding and mega-tsunamis, potentially reaching 1,000 feet. The Cascadia Subduction Zone's inactivity since 1700, coupled with climate change, intensifies the threat. Coastal land subsidence and rising sea levels could overwhelm communities, impacting thousands and vital infrastructure.
Scientists have made a surprising discovery: penguin droppings in Antarctica may contribute to cooling the continent. Ammonia released from penguin guano combines with compounds from phytoplankton, boosting the formation of cloud-seeding aerosols. These aerosols then create low-lying clouds that reflect sunlight, potentially offsetting some warming effects, highlighting the intricate link between ecosystems and climate.

Donald Trump has withdrawn Jared Isaacman's nomination for Nasa administrator just before the senate confirmation vote. Isaacman, the CEO of Shift4 and a SpaceX mission participant, was nominated in December. He distanced himself from Elon Musk's views on lunar landings during his confirmation hearing, pledging to prioritize them if confirmed.
Astronomers have detected ASKAP J1832-0911, a unique space object 15,000 light-years away, emitting powerful radio and X-ray bursts every 44 minutes. This long-period transient, observed by ASKAP and Chandra, challenges existing stellar evolution models. Scientists believe it could be a magnetar or a binary system with a magnetized white dwarf, potentially revealing new physics.
SpaceX's Starship rocket exploded during a test. The issue was a fuel reaction in an engine. The company made fixes, including better insulation. The Federal Aviation Administration approved the changes. A new test flight is set for May 27. This flight will reuse a Super Heavy booster. SpaceX aims to use Starship for Moon and Mars missions.
NASA sleep experts reveal social jet lag, a misalignment between internal body clocks and daily schedules, affects millions. Inconsistent sleep habits disrupt natural rhythms, leading to fatigue and health issues. Combat it with consistent sleep schedules, morning light exposure, and optimized sleep environments to improve overall well-being and reclaim lost energy.
