Space voyages

Today, china sent to the space the Tiangong-1 spacecraft to the space from the Gobi desert. This craft is set to dock with later Chinese crafts, to allow the scientists and engineers to practice the skills that they will need to do at 2020 to make their space station. Some reports say that it will be some living quarters in it, but more recent news say that it is made for testing.

This is interesting for me, because I like the voyages and missions that go to the space.  And I would like to see another space station, because the science fiction is becoming real.

The connections that I can draw to my life, are that with space stations, or investigation of the space, I can now more about what is going on outside our world; For example: are we alone in our solar system?. Another connection I can make is that me as an individual, or my country as a nation, or the human community can always advance to look for better thinks, nothing is impossible, and there are no limits for improoving.

The moon is leaving

The original article was posted on march 1, 1999 by  Terry Hartline

    This article is about the farewell of a moon that has accompanied  our planet ( the Earth) for a very long, long, long time; and that will do so for a lot of time from now to the future. The moon is getting away 3.8 cm per year, and making our days longer by 0.0008 seconds a century. This is happening because "The gravitational force of the Moon "pulls" on Earth's oceans and crust, creating the twice-daily tides. Likewise, Earth's gravity pulls on the Moon, distorting our companion so that it is slightly egg-shaped. These tidal effects produce bulges on the Moon's surface, and Earth pulls on these bulges a little more than on the surrounding regions because of the concentration of mass there. Earth's constant pull on the Moon's tidal bulge caused its rotation to slow down from its much faster initial spin rate to its current rate of 27.3 days".

It was amazing to me because the moon is a planet that I always watch every night; I imagine that suddenly one night I don't see the moon any longer see the moon. I also imagine the beach without waves, or never watching a eclipse.

I can make connections, for example; The waves are important to our world. Solar eclipses are beautiful, and without moon there cannot be any eclipse. I can happily say that I live in a very lucky time.
