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!
