Astronauts onboard the International Space Station (ISS) will experience New Year's Eve 16 times as the station orbits the Earth once every 90 minutes. The ISS orbits Earth at an average of 400 km above the surface travelling approximately 8 km per second, with astronauts aboard it witnessing 16 sunrises and 16 sunsets every 24 hours.

At COP 29 in Baku, countries set a $300 billion annual climate finance target by 2035 to help poorer nations cope with climate change. However, this falls short of the $1 trillion needed, and inflation reduces its value. Much of the funding consists of prior commitments, weakening efforts to limit global warming to 1.5°C and leaving vulnerable nations without adequate resources to adapt.

Is climate finance enough to tackle global warming?

ISRO's PSLV-C60 on Monday launched the SpaDeX mission from Sriharikota. SpaDeX (Space Docking Experiment) aims to demonstrate the technology of in-space docking using two small spacecraft. This technology is essential for India's space ambitions such as sending humans to Moon, sample return from the Moon, and building and operation of Bharatiya Antariksh Station (BAS) among others.

Elon Musk, who plans to colonize Mars through SpaceX, responded to an X user who asked, "Once we (humans) colonize Mars, how should governance work?" Musk said, "Martians will decide how they are ruled. I recommend direct, rather than representative, democracy." He added, "Uncrewed Starships landing on Mars in ~2 years...and crewed Starships heading there in ~4 years are possible."

ISRO will launch its Space Docking Experiment (SpaDeX) mission tonight at 10:00:15 pm from the Satish Dhawan Space Centre, Andhra Pradesh. The PSLV-C60 rocket will carry two small spacecraft into a 470 km orbit. This mission will demonstrate India's capability for complex in-space docking, crucial for future space projects like lunar missions and Bharatiya Antariksh Station.

AstraZeneca aims to eliminate lung cancer deaths by 2030 through AI-driven early detection and advanced imaging in India. Lessons from the pandemic, such as the need for sustainable supply chains and collaborative partnerships, are shaping their strategies. Their focus extends beyond cancer care to addressing broader challenges in healthcare delivery.

ISRO is set to launch the SpaDeX mission on December 30 aboard the PSLV-C60 rocket at 10:00:15 PM. The mission will dock two satellites, SDX01 and SDX02, in low-Earth orbit, using indigenous technology called the 'Bharatiya Docking System'. It will demonstrate orbital docking, power transfer, and autonomous communication, advancing India's capabilities for future space missions.

A rare 'Black Moon' will occur on December 30, marking the second new moon in a single month, a phenomenon that happens every two to three years. It will peak at 3:57 am IST. The black moon is invisible as its illuminated side faces the sun, making it undetectable from Earth, but its absence enhances star visibility.

Human brain processes information at just 10 bits/sec, far slower than internet, a study stated. Despite receiving billions of bits through our senses, this speed is considered "extremely slow" compared to typical Wi-Fi, which processes about 50 million bits/sec. Researchers suggested this slow processing may have been necessary for survival, as our ancestors adapted to a slower world.

Many insects hibernate as adults during winter, while others successfully pass the winter as immature larvae. Some insects overwinter in the pupal stage, then emerge as adults in the spring. Many large wasps seek shelter in the eaves and attics of houses or barns. Tree holes, leaf litter, and under logs and rocks are common shelters for overwintering adult insects.
