Libration

Let’s take a closer look at the term libration mentioned last week.

In astronomy, libration is a mechanical phenomenon that makes various celestial bodies appear to be “shaking” to an observer looking from another celestial body, due to their orbital properties. For example, although the same side of the Moon is always visible from Earth, thanks to libration, the visible hemisphere is slightly more than half of the Moon’s total surface area. Thanks to libration, we can see approximately 59% of the lunar surface, not 50% as expected. Libration can occur up-down (longitudinal), left-right (latitudinal) or forward-backward (altitude depending).

It can be shown that among the factors affecting the libration of the Moon;

  • Earth’s daily rotation (rotating around its own axis),
  • The Moon’s orbit around the Earth and
  • The Moon’s axis of rotation around itself is slightly inclined compared to the plane drawn by its orbit around the Earth.

Moon and Earth at the Same Time

As humans trapped on a rotating planet, we are limited to what we see from where we look. When we look at the night sky, we can see our closest neighbor, the Moon, shining, but have you ever wondered what we look like from our satellite?

Planetary scientist James O’Donoghue set up a mirror so we could all see this and satisfy many of our curiosity.

Using real NASA imagery and location data, as well as images of lunar topography, planetary scientist James O’Donoghue, a former NASA employee, created a high-resolution, computer-generated video of what the Earth looks like from the Moon and what the Moon looks like from the Earth.

The entire video covers the entire month of April 2020, with each frame in the video being 15 minutes of real-time frames, giving us a cosmic perspective we’ve never seen before.

What were you doing in April 2020, where were you on this Earth? Perhaps terrible things had happened to you, but as you can see, in the words of Galileo: “It turns!”,

E pur si muove!”

In our daily words: The world keeps turning, keep going 🙂

Artificial Intelligence and Astronauts

Space is an endless exploration and an unlimited playground of imagination. Traveling among the stars, in depths full of secrets, is one of humanity’s greatest adventures. However, in this magical world, astronauts have a companion that brightens their path even more: Artificial intelligence. It is impossible not to admire artificial intelligence, one of the technological miracles that helps us in our explorations in space, and the intelligence it displays in space. In this article, get ready to make discoveries about the world of small and intelligent robots that travel with astronauts in the depths of space!

– Artificial Intelligence in Space: Developments, Problems and Potential

Space scientists are taking major steps to explore the potential of artificial intelligence in space studies. Developed artificial intelligence systems quickly solve problems and increase efficiency in interplanetary exploration and work on space stations. In addition, thanks to artificial intelligence, valuable data can be obtained about new undiscovered planets and stars in space. However, some problems arise in the face of artificial intelligence developments in space. Factors such as communication difficulties in space, high radiation levels and energy limitations can pose obstacles to developments. Engineers and scientists continue their research to overcome these obstacles. The potential for artificial intelligence in space is extremely large. We live in an age where things that were difficult to even think of in the past are now possible. In order to use this potential at the maximum level, it is necessary to constantly develop new technologies and move forward in solving problems.

– How can effective cooperation between astronauts and robots be achieved?

There are several methods to enable effective collaboration between robots and astronauts. First, it is of great importance to establish a continuous communication channel between astronauts and robots. This communication channel can be used so that astronauts can control robots and robots can guide astronauts. In this way, coordinated work can be achieved between astronauts and robots.

Secondly, robots must have qualities that can assist astronauts. For example, it is important that robots have a robust structure to assist astronauts in harsh conditions and can move effectively in outer space. In addition, robots must have the necessary functions to ensure the safety and comfort of astronauts.

Finally, it is of great importance to distribute tasks between astronauts and robots. Astronauts can perform their duties in space exploration by working with robots. Astronauts can assign tasks to robots and have the robots perform these tasks effectively. In this way, more efficient cooperation between astronauts and robots can be achieved.

By combining all these methods, effective cooperation between astronauts and robots can be achieved. This will help carry out space research more efficiently.

– Recommendations for the Use of Artificial Intelligence in Space Explorers

Space exploration has been a dream of people for centuries, and artificial intelligence technology can add a whole new dimension to these discoveries. Here are suggestions for the use of artificial intelligence in space exploration:

Autonomous Robot Explorers: Artificial intelligence can enable robots used in space exploration to operate autonomously. Our suggestion is that the spacecraft can draw a road map for itself, detect dangers and make its own decisions when necessary.

Assist in Data Analysis: Artificial intelligence can provide valuable information to scientists by quickly analyzing data from space. In this way, more in-depth information can be obtained about new planets, stars or galaxies discovered in space.

Risk Assessment: Risk assessment is vital in space exploration. Artificial intelligence can detect possible dangers in space exploration in advance and help take necessary precautions. In this way, the safety of astronauts can be ensured.

Thanks to the use of artificial intelligence in space exploration, humanity can travel further and deeper in space. Space exploration vehicles equipped with artificial intelligence technology enable faster, more efficient and safer exploration.

As we come to the end of our article, we took a short journey about artificial intelligence in space. We took a closer look at this unique relationship between astronauts and robots ‌and renewed our hopes for how the future in deep space might take shape.
Artificial intelligence in space has become a remarkable topic with its contributions to humanity’s ongoing journey of discovery. In this space age story, astronauts bravely push their limits, while robots happily undertake tasks to support them. Collaborations enable the discovery of new horizons thanks to remotely controlled robots.
However, we still need to learn a lot about artificial intelligence technologies in space. Scientists and space agencies aim to maximize the potential of these technologies by working on more advanced and safe artificial intelligence systems. To make life in space easier and further exploration, reliable and flexible artificial intelligence systems are needed.
In the future, the bond between astronauts and robots will strengthen and humanity will continue to discover new ways to travel to the stars. Artificial intelligence in space will support these generations of exploration and help solve the mysteries of deep space.

This Week in Our Art Corner

Moscow Planetarium

The Moscow Planetarium is considered one of the largest of its kind in the world. Its main mission is to popularize scientific knowledge. The unique building consists of several floors. An important part of the building: a functioning observatory where scientists observe space objects. In order for young and adult visitors to the planetarium to see the starry sky in miniature, it is necessary to go down to the underground hall. The historical exhibition of space exploration, which attracts the attention of guests of all ages, is on the top floor. A separate section of the planetarium is filled with an array of astronomical instruments. Additionally, the building houses a family lecture hall for astronomy studies, a fascinating science theater for children, and a similar school for middle school students.
