Jupiter’s Great Red Spot is different from what an Italian astronomer observed in 1665

https://edition.cnn.com/2024/06/22/scie ... index.html

Jupiter’s iconic Great Red Spot is a massive storm that has swirled within the atmosphere of the largest planet in the solar system for years.

But astronomers have debated just how old the vortex really is, as well as when and how it formed. Some experts believed it was centuries old and first observed by Italian astronomer Giovanni Domenico Cassini in the 17th century, while others thought the storm was more recent.

Now, new research suggests that the Great Red Spot formed about 190 years ago, which means that Cassini observed something else on Jupiter in 1665. And despite being younger than previously believed, the storm remains both the largest and longest-lived vortex known across our solar system, according to researchers..............

A "First" for Lunar exploration and China as Beijing's Space Programme are the first to bring back rock samples from the "Far Side of the Moon", NASA delay Boeing's Starliner for a third successive time - a potential rescue mission by Space X would heap more embarrassment on the company and no doubt some questions over NASA and the US Government's selection policy.

Boeing “Adjusts” Starliner Return Again of NASA’s Astronauts and Reluctance to Seek SpaceX’s Help With Crew Dragon

"The extra time will allow Boeing and NASA to assess several issues that have arisen with the vehicle, including small helium leaks in its propulsion system and problems with its reaction control system (RCS) thrusters.

Despite the delays, NASA still has confidence in Starliner, with Steve Stich, manager of NASA’s Commercial Crew Program, stating that the spacecraft is “performing well in orbit while docked to the space station.”

However, the repeated extensions are a cause for concern, with many experts questioning Boeing’s ability to manage complex space missions and ensure the safety of astronauts. The issues with Starliner are not new, with the spacecraft experiencing problems during its rendezvous and docking with the ISS. Five of its 28 RCS thrusters malfunctioned, although four were eventually brought back online. Additionally, five small helium leaks were detected in the propulsion system, with one spotted before launch and the others cropping up after deployment.

The delays have raised questions about Boeing’s readiness for complex space missions and its ability to ensure astronaut safety. The company has faced numerous challenges this year, including whistleblower scandals, aircraft safety issues, and now the perilous situation with Starliner. The project was seen as a chance for redemption, but it has failed to meet expectations."

China seem to want to take over the world, with a strangle hold over many countries (Technology, Components, Rare Earth Metals, being the senior partner in the China/Russia/North Korea relationship - All with zero consideration to Global Security, Global Finances or Environmental considerations.... And next the moon? Not a pleasant thought to say the least!! My "Bunker" is becoming deeper and larger by the day.... :roll: :wink:

China’s Chang’e-6 Lunar Probe Returns World’s First Samples From Far Side of The Moon

"China has become the first country to gather samples from the far side of the moon and bring them back to Earth in a landmark achievement for the Beijing space programme.

A re-entry capsule containing the precious cargo parachuted into a landing zone in the rural Siziwang Banner region of Inner Mongolia on Tuesday after being released into Earth’s orbit by the uncrewed Chang’e-6 probe.

The return of the lunar material wraps up a highly successful mission for the China National Space Administration (CNSA) amid a wave of interest in which space agencies and private companies will build instruments and bases on the moon and exploit its resources.

The Chang’e-6 mission, named after the Chinese moon goddess, blasted off from Hainan province in south China on 3 May and touched down on 2 June on the side of the moon that is never seen from Earth. The moon shows only one face to the Earth because it is tidally locked and completes one full rotation in the time it takes to circle the planet."
