An observer on the ground films the SpaceX Crew Dragon spacecraft entering the planet's atmosphere as it returns to Earth.

Mars is just around the corner: NASA has launched its new project simulating astronauts' life on the planet.

The first of three planned missions of the agency launched a year ago, on 25 June 2023, as part of the Crew Health and Performance Exploration Analog project. The essence of the CHAPEA-1 mission is that four volunteers for a year will stay in a special "bunker", living conditions in which are as close as possible to those that can be created on the future Martian base.

You can watch the rocket launch not only from the ground: pilots filmed the launch of the SpaceX Falcon 9 from the cockpit.

⚡️ 1 light second, 1 light year, 10, 100, 1000, 10,000, 10,000 and 100,000 light years on the scale of the infinite universe.

Soyuz docking to the International Space Station

Funny from the ISS: Astronaut and SpaceX Crew-5 crew engineer Nicole Mann took a funny selfie photo through a weightless bubble that refracted her image.

☀️ The Space Observatory for Solar Dynamics (SDO) shared a recording of the Sun in various ultraviolet wavelengths. While a star looks quite calm in the visible range and with a small number of spots on it, radiation in different wavelengths of ultraviolet radiation reveals much more detail.

If Saturn could contain Earth, it would need about 700 similar balls of equal shapes and sizes to fill it completely.
Comparison: Saturn's radius is ~ 9 Earth radii, Saturn's mass is ~ 95 Earth masses.

Trajectories of planets and asteroids in the Solar System

This is what a walk on the International Space Station looks like 👨‍🚀

Animation of the descent and landing of the Huygens probe from real-world images🎥
This is the first and so far the only soft landing ever made in the Outer Solar System. It took Huygens 2 hours 27 minutes 50 seconds to parachute through Titan's atmosphere. The collision of the device with the surface of Titan occurred at a speed of 16 km/h (or 4.4 m/s).
In total, more than 500 megabytes of information were transmitted, including about 350 images. To make this video look more epic, remember that there are 1.2 billion kilometers from Earth to Titan.

❓ What do you think is in the picture above? The picture above shows a system of 79 Jupiter's moons along with their orbits. It's not easy to figure it out, but we believe you can do it!

Jupiter protects the Earth 💪

It does this by using its powerful gravitational pull to deflect potentially dangerous asteroids and space debris.

Purple Earth

Astrobiologists suggest that Earth may have once been purple. Before the dominance of plants, ancient microbes may have used a light-absorbing molecule called retinol, which gave them a purple hue.
