July space milestones
From the birth of NASA to the modern vehicles roaming Mars, July has brought together some of the most exciting chapters in space exploration.
Each of these events marked a turning point in space exploration and demonstrates how far human curiosity can go when combined with science and technology.
1958: NASA is born and a new space age begins
On July 29, 1958, U.S. President Dwight D. Eisenhower signed the law that created NASA.
Its creation was a response to the enormous challenge posed by the start of the space race, but it soon became much more than an agency dedicated to launching rockets.
NASA brought together thousands of engineers, scientists, and astronauts with a common goal: to explore space and expand knowledge about the universe.
Thanks to it, technologies that are part of our daily lives today were developed, from weather satellites to navigation systems, telecommunications, and numerous medical and technological advances derived from space research.
1969: The journey that made walking on the Moon possible
On July 16, 1969, the Apollo 11 mission took off aboard the gigantic Saturn V rocket.
For millions of years, the Moon had been an unreachable object viewed from Earth.
Four days later, on July 20, that dream of reaching it left the realm of imagination.
The Eagle module landed on the lunar surface and Neil Armstrong descended the ladder to utter one of the most memorable phrases in history.
Shortly after, Buzz Aldrin also walked on the Moon while Michael Collins remained orbiting the satellite.
In addition to its enormous symbolic impact, the mission allowed for the collection of lunar rock samples, the installation of scientific instruments, and the demonstration that manned flights could reach other celestial bodies and return safely.
1976 and 1997: Mars is no longer a mystery
After conquering the Moon, the next major objective was Mars.
On July 20, 1976, the Viking 1 probe achieved the first successful operational landing on the Martian surface.
For the first time, humanity could view images taken directly from another planet and analyze its soil, atmosphere, and environmental conditions.
Those photographs turned Mars from a simple reddish dot in the sky into a real world that could be studied.
Two decades later, on July 4, 1997, the Mars Pathfinder mission took a new step with the arrival of the small rover Sojourner.
Although it was barely 65 centimeters long, it proved that a robotic vehicle could move around another planet, study different rocks, and send information for weeks.
Its success paved the way for the great robotic explorers that roam Mars today.
2005 and 2012: Discoveries that changed our understanding of the universe
On July 29, 2005, the discovery of Eris was officially announced, an object located beyond the orbit of Neptune whose size turned out to be comparable to that of Pluto.
This finding forced astronomers to rethink what should actually be considered a planet and led, a year later, to the reclassification of Pluto as a dwarf planet.
It was an example of how science evolves when new data appears.
A few years later, on July 4, 2012, CERN announced the detection of the Higgs boson, one of the most sought-after particles in modern physics.
Its discovery confirmed an essential piece of the Standard Model and helped better understand why matter has mass, becoming one of the greatest scientific achievements of the 21st century.
2011 and 2020: The end of one stage and the beginning of another.
From the end of the shuttles to the Perseverance rover
On July 21, 2011, the space shuttle Atlantis returned to Earth and landed at the Kennedy Space Center in Florida, ending NASA's space shuttle program after thirty years of service.
Those ships made the deployment of satellites, the maintenance of the Hubble telescope, and the construction of the International Space Station possible, leaving a technological legacy that remains fundamental.
Far from signaling the end of space exploration, that moment gave way to a new generation of missions.
On July 30, 2020, Mars 2020 took off, carrying the Perseverance rover to Mars.
Equipped with instruments much more advanced than those of its predecessors, its mission is to search for signs of past microscopic life, study Martian geology, and collect samples that future expeditions will be able to bring back to Earth.
