European Space Agency - ESA’s Post

🌌🔭 ESA's #Euclid Mission and the Quest for Dark Matter! In the cosmos, mysteries abound, and none are more tantalizing than dark matter. Enter ESA's groundbreaking Euclid mission, a cosmic detective that will explore how the Universe has expanded and how structure has formed over cosmic history, revealing more about the role of gravity and the nature of dark energy and #darkmatter. 👉https://lnkd.in/eN_n6guB Credits: ESA

New post on my blog #TheSpaceBar®: Exploring the legal and policy implications behind the establishment of a universal time standard for the Moon #lunartime #LTC #coordinatedlunartime https://lnkd.in/gGZfaHJs

The long-accepted theory that a Mars-sized object named Theia collided with Earth to form the Moon has taken an intriguing twist! A new study out of the University of Nevada delves deeper into the dynamics of this massive impact billions of years ago. Researchers suggest that shortly after its formation, the Moon orbited Earth at just 5% of its current distance. Over time, tidal interactions pushed the Moon farther away. The study also sheds light on the trajectories of debris from the impact and reveals that polar orbits were the most stable in the chaotic early days of the Earth-Moon system. However, with the Moon at its current distance, such stable polar orbits no longer exist.

What kind of disinformation appears on the Chinese internet, and how to interpret it? Our CEO Isaac Stone Fish talks to AFP about China's historic lunar mission, and why that's sparked posts on the Chinese internet falsely claiming that the U.S. has faked its moon landings. "Beijing sometimes lets anti-American sentiments and false information to run rampant on the Chinese internet, to allow for an escape valve for domestic tensions, and to modulate Chinese citizens’ views," Isaac Stone Fish, chief executive of China-focused data company Strategy Risks, told AFP...Allowing conspiracy theories on the US moon landing to fester may reflect insecurity on Beijing's part on the space race between China and the United States. Chinese people can be justifiably proud of their lunar module's historic trip to collect samples. They don't need to fall victim to the old conspiracy theory that the US has staged moon landings." https://lnkd.in/eASg7MqH

The governance failure to protect the Global Commons, including Space, including the moon, seems to continue for ever ! The Global Commons are not the ultimate waste dump of the Anthropocene ! read in NATURE Stop sending human remains to the Moon US company Astrobotic’s Peregrine lander is failing because of a propellant leak, but it was due to deposit at least 70 people’s ashes on the Moon. That controversial plan was made without consulting Indigenous Peoples, despite NASA having promised such consultation in 1998. Many Indigenous Nations view the Moon as an ancient relative. It’s “not about ownership of the Moon or to enforce Diné religious beliefs,” says Alvin Harvey, Diné of the Navajo Nation and an aerospace engineer. “But rather about the right to be consulted, to uphold Native American legal rights, to hold government agencies accountable and to safeguard the Moon for future generations.” Nature | 5 min read #MOON #globalcommons #governancefailure #STOPWASTE #nativeamericans

Interesting facts about Total Solar Eclipses

The search for a Planet Nine continues with Pluto (previously thought to be Planet Nine) having been relegated to the status of a dwarf planet. The question is whether there is any evidence to suggest that such a planet exists. Searching for a possibly imaginary planet in a solar system is no mean feat. This article shares recent discoveries in the quest for a Planet Nine. The latest finding? “Imperial College London has just examined data from a now-defunct telescope obtained in 1983 which possibly shows an object three to five times the mass of Earth, orbiting c.225x further from the sun than Earth does, in roughly the area where Planet Nine is expected to be.” Astronomers from the early 1900s could’ve been right after all. Find out more about this interesting mission in the article at the link. #planetnine #astronomy #solarsystem
