China's Tianwen-2 is on its way to Kamoʻoalewa, an asteroid that currently doubles as a "quasi-moon" of Earth. The spacecraft will collect samples & bring them back home.
On its outward trajectory, Tianwen-2 looked back and got this lovely view of our planet.

🛰️ 1 to 2 Starlink satellites are falling back to Earth each day
｢ Many of these are in low-Earth orbits, which extend up to an altitude of 1,200 miles (2,000 km) above our planet. And the lifespan of low-Earth orbit satellites, such as Starlink, is only about 5 to 7 years. Soon, McDowell told us, there will be up to 5 satellite reentries per day ｣

China's Chang'e-6 mission has revealed that the moon's far-side mantle is about 100°C colder than the near side, based on analysis of 2.8-billion-year-old basalt samples. The finding, published in Nature Geoscience, provides the first physical evidence confirming long-standing theories about hemispheric differences on the moon and opens new pathways for understanding lunar evolution.

I am *really* skeptical of Bezos’ claim that data centers in space can essentially mooch off free solar power and operate at lower cost than on earth.
Ignoring the cost of sending up tons of server infrastructure, and how they would be prohibitively expensive to maintain and upgrade, and how one might have to deorbit them, I think the main problem of trying to extract massive amounts of work from solar power is COOLING.
Unlike on earth, which has a plentiful supply of cool water that removes the heat of your GPUs through conduction and which you can dump into the environment, heat dissipation in space is primarily done through infrared radiation, which is *very* inefficient in comparison.
Wikipedia says that IR radiation panels in space can be expected to dissipate up to 350 W per square meter. A gigawatt plant would need 2.8 *million* square meters of radiating surface.
lol.

On October 4, 1957, the Soviet Union launched Sputnik-1, humanity's first artificial satellite. The 58-cm aluminum sphere, powered by a two-stage R-7 rocket, entered Earth's orbit and transmitted its iconic "beep-beep" signal.
Weighing 83.6 kg, it orbited every 96 minutes, completing 1,440 orbits over 92 days before burning up in the atmosphere. This landmark achievement marked the dawn of the space age, revolutionizing science, communication, and navigation worldwide.
Last images of the morning from both telescopes. Aimed them to the #planet #Jupiter. This first image is by the Odyssey Pro and the second from the s50. Though you can see Jupiter clearly on the first image none of the moons are visible. In thebs50 image Jupiter is to bright, but you can clearly see its moons #Ganymede (to the left) and #Callisto (to the right). #unistellar #odyssey pro #space #astronomy #amateur #seestar #S50
The planet Jupiter as seen by the s50. It has the shortest day in the Solar System: it spins so fast that one day on Jupiter lasts less than 10 hours! 💨
The planet Jupiter as seen by the Odyssey Pro. The largest planet, a gas giant with colorful swirling clouds and the massive, centuries-old storm known as the Great Red Spot. It has no solid surface.
