Un Día Entero Visto desde un Satélite Geostacionario



Un satélite geoestacionario es aquél que gira alrededor de la Tierra a la misma velocidad que ésta. Por lo tanto, siempre tiene a la vista el mismo lado del planeta.

El que hace posible estas imágenes está ubicado sobre Oceanía, razón por la cual siempre tiene frente a sí a Australia y otros territorios de este continente.

Carreteras Más Resistentes y un Mar Más Limpio



Interesantísimo este proyecto de una empresa holandesa, que permitiría tener mejores carreteras, evitaría el consumo de un hidrocarburo cuya producción es altamente contaminante y a la vez generaría incentivos para limpiar el mar.

The History of Space Exploration on a Single Space Map

Humans have dreamed about spaceflights forever but only in the second half of the 20th century were developed rockets that were powerful enough to overcome the force of gravity to reach orbital velocities that could open space to human exploration.

Everything started in 1957 when the Soviets launched the first artificial satellite, Sputnik 1, into space. The first U.S. satellite, Explorer 1, went into orbit two years later in 1958. In 1961 the next milestone is space exploration has been achieved – Yuri Gagarin became the first human to orbit Earth. His flight lasted 108 minutes, and Gagarin reached an altitude of about 202 miles (327 kilometers). We had to wait 8 years to 1969 for Astronaut Neil Armstrong to take “a giant step for mankind” as he stepped onto the moon… The road to space exploration has been long and often bumpy but we have managed to achieve a lot.

The awesome poster called Chart of Cosmic Exploration documents every major space mission starting from the Luna 2 in 1959 to the DSCOVR in 2015. The map traces the trajectories of every orbiter, lander, rover, flyby, and impactor which ever left the Earth’s orbit and successfully completed its mission. Additionally each poster features an array of over 100 exploratory instruments with hand-illustrated renderings of each spacecraft. It’s awesome and beautiful!
