Before it took off, the bird ate parts of its own liver, kidneys, and gut. That was the only way to be light enough to fly. Then it flew 8,425 miles from Alaska to Australia, in 11 days, without eating, drinking, or landing once.
The bird is called B6. It's a bar-tailed godwit, four months old, weighing about as much as a can of beans. In October 2022, scientists at the US Geological Survey tracked its flight from Alaska all the way to Tasmania. The trip took 11 days and 1 hour. It is still the longest non-stop flight of any animal on Earth.
For two weeks before takeoff, godwits eat until they almost double in weight. Fat ends up being 55% of their body, more than any bird ever measured. Then they shrink their own insides. About a quarter of their liver, kidneys, stomach, and intestines gets broken down and reused for fuel, making room for the extra fat and cutting weight. Their heart and wing muscles grow bigger at the same time.
They never drink along the way. The water they need comes out of burning fat, the same reaction their muscles use for energy. They also never really sleep. B6 flapped its wings for 264 straight hours, cruising around 35 miles per hour with help from storm tailwinds. By the time it landed, it had lost almost half its body weight. The shrunken organs grew back over the following weeks.
Scientists still cannot explain the navigation. B6 had never made this flight before. Adult godwits leave Alaska weeks earlier, so young birds fly alone with nobody to follow. How a four-month-old bird finds its way across 8,425 miles of open ocean to a place it has never seen is still an open question.
About 100,000 bar-tailed godwits leave Alaska every fall. Most of them land in New Zealand or Australia 10 or 11 days later, having eaten parts of themselves to get there.

Integration is largely complete, with the missile paired with the Bars radar and indigenous data links. DRDO is expanding the range of the Astra Mark-2 missile to over 200 km.
IAF will procure 700 missiles for Su-30MKI and Tejas Mk1A fleet.
Astra Mark-2 will be superior to Pakistan's PL-15E (145 km) and comparable to China's PL-15 (200-300 km).

The Soviet N1 was a massive, five-stage super-heavy launch vehicle developed to take cosmonauts to the Moon, acting as the USSR's rival to the US Saturn V. Designed by OKB-1, it stood 105 meters tall and featured 30 engines on its first stage (Block A). All four test launches (1969–1972) failed, leading to the program's cancellation.
