Space titans Elon Musk and Jeff Bezos are locked in a new lunar race, mirroring the tortoise and the hare. Musk champions rapid, iterative development for a Moon city, embracing failure for speed. Bezos, via Blue Origin, signals a deliberate, step-by-step approach, emphasizing long-term reliability. Their contrasting philosophies shape humanity's next steps beyond Earth.

A record-breaking $44.6 million sale of a Stegosaurus fossil has ignited a global debate. While private collectors view these ancient remains as status symbols and investments, scientists fear losing crucial access for research. The booming trade, fueled by US laws allowing private ownership, risks locking away vital pieces of Earth's history.

"We are targeting 2028 for Chandrayaan-4," Isro chairman V Narayanan had earlier said. According to Isro officials, they had zeroed in on four sites of the Mons Mouton (MM) and found one of them suitable for landing on the lunar surface. Mons Mouton is a region on the Moon. Officials said they had identified locations -- MM-1, MM-3, MM-4 and MM-5. Of them, MM-4 was chosen for the landing.

NASA's colossal Artemis II moon rocket, stretching nearly the length of a football field, is poised to send four astronauts on a 10-day lunar journey. This mission, a crucial step towards returning humans to the moon, faced a delay due to hydrogen leaks detected during a recent countdown rehearsal. The launch is now targeted for at least March.

SpaceX is now prioritizing a lunar settlement over Mars, according to Elon Musk, aiming for a self-sustaining city on the Moon within a decade. This strategic shift, driven by logistical advantages like more frequent launch windows, aligns with US lunar exploration goals. While Mars remains a long-term objective, the Moon offers faster progress for establishing a permanent human presence.

AI researcher Dr. Roman Yampolskiy warns that artificial general intelligence could automate nearly all jobs by 2027, driving unprecedented unemployment. Unlike past revolutions, few human roles would remain, limited to oversight, AI intermediaries, counseling, or niche human-made crafts. He predicts society may reach a technological singularity by 2045, where AI progress outpaces human comprehension, fundamentally challenging the relevance of human labor.

Covid-19 lockdownshas unexpectedly caused a surge in methane, a potent greenhouse gas. This has happened because pollution reductions weakened the atmosphere's natural methane-clearing ability. Methane levels then rose at a record pace. This gas is a major contributor to climate change. Many nations have pledged to cut methane emissions by 2030.

Indian-origin scientist Meha Jain has won the ASU–Science Prize for Transformational Impact for her work using satellite imagery and AI to study how smallholder farmers adapt to climate stress. Her research highlights their adaptive strategies and environmental risks like groundwater depletion, linking advanced science with practical solutions for vulnerable communities.
