A score of test tubes with samples of lunar dust brought from the terrestrial satellite on the Apollo 11 spacecraft have been found in an old warehouse in California, United States, after 43 years unaccounted for. They were labeled and dated July 24, 1970.
Until today, the most accepted belief was that 4,500 million years ago a gigantic object collided with the Earth and, from the detached fragments, the Moon was born; and that the impact caused such heat that all the hydrogen evaporated and was lost in space, leaving both the Earth and its satellite dry. Later, the water returned to Earth in meteorites and to the Moon in comets.
As explained by the Instituto de Astrofísica de Canarias (IAC), the minimum number is four (including eclipses of the Moon due to penumbra), two eclipses of the Sun, total or annular, and two eclipses of the Moon. This happened in 1999, 2003, 2005, etc.
On April 25 there will be a partial lunar eclipse that will be visible in Europe, Africa, Asia and Australia. It is a short-lived eclipse, which will begin at 7:54 p.m. and end at 8:21 p.m. in Universal Time (TU). The twilight eclipse will begin at 6:04 p.m. and end at 11:10 p.m. TU. Its obscuration will be limited, hence we speak of a penumbral eclipse, and the phenomenon can be seen without the need for any optical instrument.
Will there be a stable lunar base on the Moon? The European Space Agency, ESA, is working on a project to build a lunar base thanks to 3D printers. We explain in pictures how it works and

Building a base of operations for the human being on the Moon is not an easy task, since it would involve several months of works, working in unfavorable conditions and in the absence of gravity, and the astronaut-workers would have to remain on our satellite at all times. that the work lasted. However, new 3D printing technologies offer an alternative that makes the idea of having a lunar base seem no longer so difficult to come by.
