🛸 International Space Station: Closer than you thought…
It seems that the ISS is somewhere "there", in the endless space. But in fact - it is only 400 km above us. It's about like a ride from New York to Washington, well, from Paris to Brussels.
For comparison:
- The Moon - 384,400 km
- Mars - from 54 to 401 million km

🚀 January 16, 2025: a second attempt to catch the Starship booster (IFT-7, Booster B14) — and again, success. This is not about luck, but about engineering magic.
Imagine: an object 70 meters long, 10 meters in diameter, and weighing about 350 tons, speeding towards Earth at the speed of sound. At an altitude of less than 2 km, he slows down at a breakneck speed, perfectly enters the "embrace" of the giant steel towers and stops gently - at the moment of precise touch.
It looks like it's a long-established routine. But it is still one of the most difficult tricks that humanity has ever tried to pull off in the air.

🌏 The Earth's Forgotten Shield.
The Earth's magnetic field is not just a compass needle, but our true protective dome. It deflects the solar wind, a stream of charged particles from the Sun that could turn the planet's surface into a microwave oven.
Some of these particles still manage to penetrate the field and get trapped in the Van Allen radiation belts, while others travel towards the poles, where they collide with the atmosphere and create auroras.
Without this magnetic "shield," Earth could have a similar fate to Mars, with no atmosphere and no life.

🔥 At the Arc Jet facility, NASA engineers test materials and structures that protect spacecraft during re-entry into the Earth's atmosphere.
They create extreme temperatures and forces that mimic real-world re-entry conditions.

🟠 60 years with Mars: from the first images to drone flights.
Exactly 60 years ago, the Mariner 4 probe transmitted the first images of Mars to Earth. Black and white and blurry by today's standards, they marked the beginning of a new era in the exploration of the Red Planet.
Since then, we have been observing Mars from orbit, from its surface, and even from the air:
— 1965: the first photos by Mariner 4;
— 1976: Viking landing and the first panoramas;
— 1997: the mini-rover Sojourner began moving across Mars;
— 2004–2019: Spirit and Opportunity turned short-term missions into multi-year journeys;
— 2015: Curiosity captured a blue-tinted Martian sunset;
— 2019: an orbital spacecraft captured an avalanche;
— 2021: Perseverance and Ingenuity made the first flight on another planet.
From grainy footage to drone videos, six decades have transformed Mars from a distant point to a studyable world.

The dance of ocean currents.
Visualization based on the NASA ECCO model shows how waters move across the planet.
The model combines data from satellites, buoys, and other sources to help scientists study the dynamics of the oceans and monitor processes affecting climate, ecosystems, and weather conditions.

💫 5 galaxies?
At first glance, it seems that five galaxies are locked in a cosmic fight. But this is only partially true: the blue spiral galaxy NGC 7320 is much closer to us, just 40 million light-years away. However, the real drama unfolds 290 million light-years away, where four other galaxies are connected by a powerful gravitational dance.
Passing each other at a distance of only about 20,000 light-years, they tear apart gas clouds, trigger star-forming bursts, and extend giant tidal tails. Together, these five galaxies contain approximately 1.2 trillion (!) stars, slowly but relentlessly moving towards merger.
