#RDC|🇨🇩La MONUSCO a été refusée d'entrer à Mambasa après une attaque des ADF. Les éléments de la mission ont négocié et collaboré avec la population locale pour assurer leur protection dans la région.

That photo is still exactly where Duke left it. But the image is gone. No atmosphere on the Moon means no wind to blow it away. But it also means no shield against solar UV and cosmic radiation - the organic dyes and polymers in the photo paper would break down and bleach out within years, not decades. The thermal cycling makes it worse: +120°C in direct sunlight, -130°C during the lunar night. That 250-degree swing happens every month. The repeated expansion and contraction would crack and embrittle the paper and emulsion layers over time. So by now, 50+ years later, it's almost certainly a blank, cracked, brittle rectangle still sitting exactly where Duke placed it.

Astronaut Charles Duke left a photo of his family on the Moon during the Apollo 16 mission in 1972.

I wish African leaders would stop doing this. The arts are not the enemy. That idea was planted in their heads by the west that sabotaged the development of science. When foreign companies are mining in Africa, they're blocking development of those skills. When they insist on economic policies of export of raw materials, that's how they block manufacturing. That's not the fault of literature. In fact, it's people in literature who point that out.

It’s been the honor of a lifetime to help share this mission. I hope you carry this wonder with you.

@SirAlexas Atmospheric braking. The spacecraft will not be accelerating towards earth surface, but performing a careful descent maneuver by plunging into the atmosphere at 40,230 km/h but it will be decelerated as it plunges through the denser parts of the atmosphere and land at 32 km/h.

A dense interstellar cloud with a significant high hydrogen would shrink our heliosphere to less than 1AU. Can cause depletion of the ozone layer and oxygen. Past extinction events on earth maybe related to a passage of our solar system through a dense interstellar cloud.

However, the G cloud is about 30 times dense than the local interstellar cloud. Consequently, our heliosphere will be squashed, exposing the planets in the solar system to higher than normal exposure to cosmic rays.

Carbon-14 is a radioactive isotope. Can be formed when galactic cosmic rays from distant stars interact with our atmosphere. Some of the radioactive isotopes found in our oceans may indicate evidence of our solar system's past interstellar cloud passages.

A number of stars in our Milky Way Galaxy actually belong to a separate galaxy that merged with the Milky Way. For instance, the ESA Gaia telescope discovered Shiva & Shakti, two ancient stars believed to have been merged with the Milky Way Galaxy 12–13 billion years ago.
