From the Top 3 Space Agencies in the world, NASA is the most popular one. NASA is a US-based organization that was established in 1958. And since then till today, it has achieved many great achievements in cosmology. There are no other space agencies better or more popular than NASA in space research. It has discovered many distant objects in the universe that we had never known.  The new discovery of the agency helps us to understand our Cosmos very deeply.  They helped us to understand black holes, nebulae, stars and many more objects in the universe. 

According to a fact, when a survey of people from various countries was conducted to determine which space agencies they are familiar with, it was discovered that NASA is the only space agency that people are aware of. And also this agency is popular worldwide. 

NASA has had a lot of success in the last few years. NASA is the only space agency that has visited completely undiscovered planets like Jupiter and Saturn in 1972. Apart from this, NASA is also one of the first space agencies that showed the world outside the solar system to our human civilization. NASA’s most famous space research program includes Hubble Space Telescope, Viking 1, Chandra X-ray Observatory, Voyager 1 and Voyager 2, Skylab, space shuttle, Apollo, etc.

NASA has made the world aware of mega-structures like cosmic bodies, uncountable galaxies, star clusters, supernovae, nebulae, etc. And somewhere, if we know today that there is also a different world outside this earth or solar system, then most of its credit goes to NASA’s Hubble Space Telescope. America is the first country to land the first man on the moon. There are currently several NASA missions underway. The annual budget of NASA is $22.6 billion.

From the Top 3 Space Agencies in the world, The second most popular space agency is the Indian Space Research Organization. ISRO is one of the top space agencies in the world. ISRO was established in 1969, even before Russian and China space agencies. So, India had space technology even before countries like China and Russia. The Indian space agency has also discovered water on the moon.

In 2008, due to Chandrayaan 1 mission, ISRO proved that water is available on the moon in ice form. By launching 104 satellites into space with a single rocket (PSLV-C37), ISRO set a new world record in 2017. SpaceX later broke this record. India’s space agency successfully landed its spacecraft on Mars in the first attempt. Even a space agency like NASA took 2 attempts to soft-land its spacecraft on Mars. But Indian space agency ISRO successfully landed its spacecraft on Mars in the first attempt. 

On the first try, India’s ISRO had successfully achieved its first Mars mission, Mangalyaan 1, in a budget of only $ 75 million. India is the 4th country that did a soft landing on the Moon, and Indian astronaut Rakesh Sharma was the first Indian to travel in space. ISRO has a PSLV (Polar Satellite Launch Vehicle) rocket which is one of the best launch vehicles in the world. The annual budget of this space agency is $1.5 billion.

From the Top 3 Space Agencies in the world. The third most popular space agency is China National Space Administration (CNSA). CNSA is one of the most popular and most successful space agencies globally. This administration was established in 1993, thirty-six years after establishing NASA. From 1993 till today, CNSA has done an excellent job exploring space. CNSA has sent many spacecraft and satellites into space.

There are about 4500 satellites in space, and only CNSA has sent 412 out of 4500 satellites in space. China sent its space station named Tiangong-1 in space in 2011. China has sent 11 astronauts to space. The China National Space Administration successfully made the first soft landing on the moon in 2014, using Change 3 as its first robotic lunar lander and rover. 

CNSA has also made many plans for the future. As per a report, in 2029-2030, China is also preparing to send such a spacecraft in space that will capture Jupiter and Saturn images closely and send some more useful information. The annual budget of CNSA is $8.9 billion.
