"Where no man has gone before"
Fukan belongs to one of the rarest types of meteorites - pallasitam.
If there is no air in space, then how does the Sun burn?
Good question! The sun doesn't burn by combustion - an exothermic oxidation reaction (chemical, interaction between atoms).
A thermonuclear fusion reaction occurs on the Sun. The hydrogen bomb, in general, is only very large.
Artemis I - First Flight Test of NASA’s Deep Space Exploration System
- Artemis I will be the first integrated flight test of NASA’s deep space exploration system: the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems at Kennedy Space Center in Cape Canaveral, Florida. The first in a series of increasingly complex missions, Artemis I will be an uncrewed flight that will provide a foundation for human deep space exploration, and demonstrate our commitment and capability to extend human existence to the Moon and beyond. During this flight, the uncrewed Orion spacecraft will launch on the most powerful rocket in the world and travel thousands of miles beyond the Moon, farther than any spacecraft built for humans has ever flown, over the course of about a three-week mission.
Artemis I - Mission Time
- Originally, the mission was planned to follow a circumlunar trajectory without entering orbit around the Moon. However, current plans have the Orion spacecraft spend approximately three weeks in space, including six days in a distant retrograde orbit around the Moon.
Rotation of the moon
Due to tidal interactions, the Moon is, as it were, tied to the Earth and always faces it with the same side. However, modern computer technology and a large number of detailed images of the Moon obtained by the Lunar Reconnaissance Orbiter made it possible to create this video about the rotation of the Moon.
The video begins with a familiar view of the Earth's moon. However, shortly after the start, the Eastern Sea, located just below the equator, enters the frame - a huge crater with a dark center, which is difficult to see from Earth. The entire lunar month is compressed into a 24-second video. It is clearly seen that on the side of the Moon facing the Earth, there are many dark lunar seas, while on the far side there are more light hills.
