@lanabeesfw @ZinniaMintLove What ‘til you learn about Prairie Dogs!

They describe what people are wearing (including colors) and if they’re carrying a gun/weapon.

This is a spent Chinese Long March 3B rocket body, imaged by a Vantor WorldView Legion satellite from 88 km away.

The image quality is not simply about range. It reflects the strength of Vantor’s advanced WorldView constellation and high-performance imaging hardware, which enable detailed observation of objects in orbit.

It’s a powerful example of Vantor’s NEI tasking through our WorldView Space product line: using high-resolution satellites to look out into space and capture detailed imagery of objects in orbit.

Why does that matter? Most tracking systems can show where an object is. WorldView Space NEI helps show what it is, its structure, orientation, condition, and potential risk. It can also support Movement Analysis, helping operators understand whether an object is intact, tumbling, spinning, or otherwise changing behavior over time.

That level of detail is especially important for large rocket bodies like this one. They are big, long-lived debris objects that share orbits with critical infrastructure, including communications, Earth observation, weather, science, and national security satellites. A single collision involving an intact rocket stage can create thousands of new fragments, increasing risk across already crowded orbital regions.

As launch activity accelerates, we need to understand not just where objects are in space, but what they are, how they are moving, and how they may behave over time.

The erasure of the Kingdom of Kush, the Malian Empire, the Kingdom of Dahomey, Great Zimbabwe, and dozens of other sophisticated African civilizations from global historical education was not an accidental omission — it was a deliberate intellectual project pursued by European colonial academics who understood that the premise of African inferiority required the elimination of evidence that Africans had built literate, mathematically sophisticated, architecturally advanced, and diplomatically complex civilizations centuries before European contact.

The Mali Empire at its peak under Mansa Musa in the early 14th century controlled territory larger than Western Europe, administered a complex trans-Saharan trade network in gold, salt, and manuscripts, and maintained the University of Sankore in Timbuktu, which enrolled an estimated 25,000 students and housed a library containing between 400,000 and 700,000 manuscripts covering mathematics, astronomy, medicine, law, and theology. When Mansa Musa performed his pilgrimage to Mecca in 1324, his caravan included 60,000 people and 100 camels each carrying 136 kilograms of gold. He distributed so much gold during his passage through Egypt that he caused a decade long inflation of gold's value across North Africa and the Middle East, a macroeconomic event documented by Arab historians and economists of the period.

Great Zimbabwe, the stone city complex in present day Zimbabwe whose construction required sophisticated engineering knowledge and administrative organization to quarry, transport, and assemble without mortar, was attributed by early European colonial archaeologists to Phoenicians, Arabs, and ancient Israelites in sequence, each attribution motivated by the determination to find any explanation other than the one supported by the archaeological evidence: that it was built by the ancestors of the Shona people who inhabited the region when Europeans arrived. The archaeologist J. Theodore Bent, who conducted the first formal excavation in 1891, was explicitly commissioned by Cecil Rhodes with instructions to find evidence of a non-African origin.

The systematic suppression of African historical scholarship extended into the colonial educational apparatus, which ensured that generations of both African and European students received no substantive instruction in pre-colonial African civilization, creating an intellectual vacancy that colonial racial ideology filled with the fiction of a continent without history.

Another of my favorite views from the @Space_Station, the Northern and Southern Patagonian Icefields. I was in awe of the splendor of these glaciers on my first mission, surrounded by mountains, with their tongues melting into pristine turquoise lakes. I vividly recall an iconic view from one of my first spacewalks, as I gazed down at @Astro_Christina in her spacesuit below me, the lakes appeared just beneath her feet.

Of course, viewed over time, the retreat of these majestic bodies of nature tells a sad tale of their demise as our climate changes. Unfortunately, the South American icefields are melting at some of the highest rates on Earth, contributing to rising sea levels.

Photo 1: Note the lines running down the glaciers, marking their active flow.

Photo 2: Zoomed area of the edge of one glacial tongue, you can observe the chunks of ice breaking off and melting away.

@H90Chad @archeohistories Chad, I thought people as racist as your posts indicate were caricatures. Compared to this woman,you are worthless white trash. If you were representative of the majority of your country's population your dear leader would have turned your country into a " shithole country".

@thepanamacanal Nice headline, but leaves me wanting more information. How does it work? Not contradicting you, just interested in the engineering behind it.

@teslaenergy @cybertruck What would the effect of this be on battery lifespan? Li- ion batteries have 1000 to 1500 charge cycles, so unless the percentage of total capacity available for Vehicle to Grid is limited, battery lifespan could be noticeably reduced.

[Rep. Brian Fitzpatrick 🇺🇸 @RepBrianFitz]

The following facts must be emphasized when assessing any proposed peace agreement:

-Vladimir Putin has never once kept a single promise that he has made regarding Ukraine. Not once. Ever. And he’s not about to start now. Any agreement that requires any element of trust placed in Vladimir Putin’s “promise” is not worth the paper it is written on.

-There are only two enforceable security guarantees: 1) NATO Article 5, or 2) a treaty that is passed by the U.S. Congress. Anything outside of this is just a Budapest Memorandum 2.0 — a completely unenforceable and empty promise that led to the invasion of Ukraine, and will lead to the future dismantling of Ukraine.

-Any “forced reduction” of the Ukrainian military means future increased pressure, risk, and danger to the European, NATO, and U.S. military.

-Any official recognition of Russian-occupied Ukrainian territory as “Russian territory,” and any official prohibition of Ukraine from being free to decide what alliances to join, would, for the first time in American history, create a brand new precedent of officially rewarding a dictator for invading a sovereign nation, and officially punishing a victim nation that was wrongfully invaded. What a terrible precedent to set. What a terrible message to send.
