🚀 Apollo 8 VS Artemis 1: a new path to the Moon.
Although the goal is the same — the Moon, the routes have changed significantly.
The Apollo 8 mission (1968) used a direct trajectory, 'Trans-Lunar Injection,' providing a close orbit around the satellite.
Artemis 1 (2022) chose a 'Distant Retrograde Orbit' (DRO), testing the limits of the Orion capsule's capabilities and the stability of gravity for long-duration missions.
These paths demonstrate the evolution of technology and preparation for longer missions to the Moon.

🌍 Earth's rotation over 24 hours.
An astrophotographer captured the night sky using a fisheye lens for an entire day, taking automatic exposures, and then stabilized the frames using their own software.
The result is an impressive time-lapse showing the movement of stars over the Earth.

🌛 China on the way to the Moon.
China has successfully tested the new manned spacecraft Mengtian and an experimental version of the Long March 10A rocket.
The test confirmed the operation of the spacecraft's emergency system and the controlled landing of the rocket’s first stage in the ocean.
A step toward the ambitious goal — a manned mission to the Moon by 2030.

✈️ Aircraft fuel tank inspection.
Fuel tanks are part of the wing and fuselage structure, so technicians enter them to examine elements that are inaccessible from the outside. They check ribs, fasteners, sealant, wiring, pumps, and connectors for cracks, corrosion, leaks, or electrical faults.
The process is safe: the tank is drained in advance, ventilated, fuel vapors are removed, and monitored in real time.
Technicians use protective gear and work under supervision — all of this is necessary to keep airplanes safe during thousands of hours of flight.

What happens if a star approaches a black hole? 💥
This video clearly demonstrates the process: the star gradually approaches the black hole, its orbital speed increases, and at the moment of close encounter the outer layers of the star begin to tear away. Most of the stellar material is scattered into interstellar space, but some of the material is captured and starts rotating around the black hole, forming a bright accretion disk.

Sunset on Mars, captured by the Curiosity rover ☀️
Due to the peculiarities of light scattering in the atmosphere of the red planet, the sky turns blue during sunset.

Is the speed of light really that high?💡
A ray of light can circle the Earth seven and a half times in just one second. Seems fast, let's scale it up.
To cover the distance to the Moon, light takes already 1.255 seconds. And to travel from Earth to Mars — about 3 minutes. And these are just the nearest neighbors in the Solar System.

🌟 After the star's outburst.
In 2002, a dim star in the constellation Monoceros suddenly became 600,000 times brighter than the Sun. This is about V838 Monocerotis, located approximately 20,000 light-years from Earth. During the outburst, the star expanded sharply in size and illuminated the dust surrounding it.
It was these dust shells that NASA captured using the Hubble Space Telescope over several months in 2002. The images show light traveling through increasingly distant layers of dust, creating a "light echo" effect.
Although the star itself has long returned to its previous brightness, its outburst continues to help scientists better understand stellar evolution in the Universe.

🌍 Water against fire and noise.
During rocket launches and fire tests, NASA floods the launch pad with huge amounts of water.
This system is called Ignition Overpressure Protection and Sound Suppression (IOP/SS). It:
— Reduces the thermal load from the engines;
— Dampens the shock wave and reflects acoustic energy;
— Prevents dangerous vibrations;
— Helps suppress possible fires.
Without this 'water shield,' the launch infrastructure literally would not withstand the power of rocket engines.

🪐 Zero-gravity training.
The best way to prepare for spacewalks is to train underwater in NASA's 12-meter pool in Houston.
Safety staff adjust the suit's weight to create perfect neutral buoyancy. Thanks to such training, the first spacewalks feel familiar and safe, despite their extremity.

🛰 Orbital “somersault” of the ISS.
The ISS rarely changes orientation, but before and after the SpaceX CRS-33 mission, the station performed a turn for a reboost.
In a 60x timelapse — a complete orbital “somersault” from the Atlantic to the Pacific: sunset, thunderstorms with lightning, atmospheric glow, moon glare, stars, and sunrise — all in one shot.
