Space Exploration and It's Miracle Outcome
On March 16th, 1926, an American college professor and scientist, Robert Goddard, built the first liquid propellant rocket. From there to launching the James Webb Space Telescope (JWST) recently, we have reached an astonishing point in space exploration within a century. To know our outer place, to know our neighbors and far beyond, we have been using our finest talents and developed ways. There are more miles to reach, yet we have achieved quite a great outcome with our modern civilization.
First of all, reaching outer space and a human made object to touch the moon was a miracle that was just dreamed decades ago. This natural satellite of ours was created from an impact between the Earth and a Mars-sized body; this mysterious fact couldn't have been found out if we had never put our foot on the moon's surface. This is an example to open more probable paths for many unknown wonders out there about planets' and systems' formation.
Secondly, with reaching the moon, another miracle is our twin explorers who crossed a long distance and time in space, Voyager-1 and Voyager-2. This very recently, about 47 years have passed since these two were launched, they have thrived through the space and crossed the heliopause, the boundary between the heliosphere. Throughout their journey, they have given us invaluable knowledge about various planets' unique systems of rings and magnetic fields around them in our solar system, and beyond it, with 1970's human made technology, is till now mind-boggling. These twins contain a message to convey our existence to our expected yet probable strangers out there. Despite their initially indented mission in the solar system, they are now burdened with gaining knowledge about UV sources of stars and influence in the boundary between the Sun's influence and interstellar space.
There is another saddening yet personally loved mission: the Cassini-Huygens's Saturn mission, commonly known as the Cassini, was sent to examine the Saturnian system's rings, a lot of moons orbiting it, and the Saturn itself. The Cassini did the Doppler wind experiment on Saturn's moon, the Titan, to determine the direction and strength of the Titan's zonal winds. It also looked to the reason behind the famous ring of the Saturn.

When we are talking about space exploration, the names NASA, ESA, Roscosmos (Rosaviakosmos), and SpaceX are very well known. Apart from NASA and Roscosmos, the SpaceX is a hot topic for its owner and also for its success in space exploration attempts. The SpaceX has made the cost down significantly of space exploration with its controlled landing on a planet's surface. The SpaceX is also underway to make civilization on Mars and is doing its best to make Mars habitable and an alternative to humans.

Lastly, the recently launched James Webb Space Telescope (JWST) has been providing images that surprise astrophysicists as well as the public like me. Like the Voyager twins, JWST also contains a gold plate with information regarding our existence in various ways to decode. The JWST is out there in search of the early universe and its mysterious creation and things it has later created as a result. Because of being a modern and developed human-made technology, JWST has been providing more in depth and detailed information than the Hubble Space Telescope, the Voyager twins, and many others out there for our curiosity. JWST's optimized IR radiation that mostly cannot penetrate Earth’s atmosphere allowed it to penetrate dust clouds to see the birthplaces of stars and planets.

Space's name resemblance with the words vast and limitless, the continuously expanding process is making it more mysterious and making us more curious about it. Renowned Einstein's quantum theory, Dirac's Dirac equation, proposed dark matter, anti-matter, and our known space, time and gravity have their own unique characteristics to this mystery of space. We, humans are putting our knowledge to use to know every bit of it, even if it is thousands of light years away from us. The earned perfect knowledge about space is less but has the possibility of even being wrong. Its obviously mysterious, but we are curious as well to begin with, slowly but gradually we are knowing things with our exploration and someday we will reach the point of every possible unknown space to know them.
