Here are the top 10 best NASA’S Missions.

Number 10: Pioneer

Pioneer 10 and Pioneer 11 were the first spacecraft to visit the outer planets of our solar system, Jupiter and Saturn. They also flew through the asteroid belt, a region of rocky debris between Mars and Jupiter. Pioneer 10 was the first to fly by Jupiter in 1973, taking stunning close-up photos of the giant planet and its Great Red Spot, a huge storm that has been raging for centuries. Pioneer 11 followed a year later, and also flew by Saturn in 1979, discovering two new moons and a new ring around the ringed planet. Both spacecraft are now on their way out of the solar system, carrying plaques with messages for any alien civilizations that might encounter them.

Number 9: Voyager

Voyager 1 and Voyager 2 were launched in 1977, and they continued the exploration of the outer planets started by Pioneer. They made many important discoveries about Jupiter and Saturn, such as the rings around Jupiter and the volcanoes on its moon Io. Voyager 2 also visited Uranus and Neptune, the only spacecraft to do so, and found out new things about their moons, rings, and atmospheres. Both Voyager spacecraft are still sending back data as they explore the edge of the solar system and the beginning of interstellar space. They are also carrying golden records with sounds and images of Earth, as a greeting to any extraterrestrial beings that might find them.

Number 8: WMAP

WMAP stands for Wilkinson Microwave Anisotropy Probe, and it was launched in 2001 to study the cosmic microwave background radiation, or CMB. The CMB is the leftover heat from the Big Bang, the event that created the universe about 13.8 billion years ago. By mapping out the tiny variations in the temperature of the CMB across the sky, WMAP was able to measure the age, shape, size, composition, and history of the universe with unprecedented accuracy. WMAP helped us confirm that the universe is expanding faster than expected, due to a mysterious force called dark energy.

Number 7: Spitzer

Spitzer is a space telescope that observes the universe in infrared light, which is invisible to our eyes but can reveal hidden details of objects that are too cold, dusty, or distant to be seen in visible light. Spitzer was launched in 2003 and has made many amazing discoveries, such as finding new planets around other stars, studying the birth and death of stars and galaxies, and detecting organic molecules that are essential for life.

Number 6: Spirit & Opportunity

Spirit and Opportunity were twin rovers that landed on Mars in 2004, with a mission to explore the geology and climate of the red planet. They were designed to last for only 90 days, but they exceeded all expectations and operated for much longer. Spirit lasted until 2010, while Opportunity lasted until 2018. Together, they covered more than 45 kilometers (28 miles) of Martian terrain, climbed hills, descended into craters, survived dust storms, and found evidence of past water activity on Mars.

Number 5: Cassini-Huygens

Cassini-Huygens was a joint mission between NASA and ESA (the European Space Agency) to explore Saturn and its moons. Cassini was an orbiter that arrived at Saturn in 2004 and spent more than 13 years studying the planet’s rings, magnetosphere, weather, and moons. Huygens was a probe that detached from Cassini and landed on Titan, Saturn’s largest moon, in 2005. It was the first landing on an outer solar system moon, and it revealed a fascinating world with lakes and rivers of liquid methane and ethane. Cassini-Huygens made many groundbreaking discoveries, such as finding geysers on Enceladus, another moon of Saturn that might harbor life under its icy crust.

Number 4: Chandra

Chandra is another space telescope that observes the universe in X-ray light, which is emitted by some of the most energetic and violent phenomena in nature. Chandra was launched in 1999 and has been observing black holes, supernovas, neutron stars, galaxies, clusters of galaxies, and more. Chandra has helped us understand how these objects form, evolve, interact, and affect their surroundings.

Number 3: Hubble

Hubble is perhaps the most famous space telescope of all time. It was launched in 1990 and has been capturing stunning images and data of the cosmos ever since. Hubble has revolutionized astronomy by revealing the beauty and diversity of the universe, from planets in our solar system to distant galaxies and nebulae. Hubble has also helped us measure the expansion rate of the universe, discover dark matter and dark energy, and find evidence for the existence of black holes.

Number 2: Curiosity

Curiosity is a car-sized rover that landed on Mars in 2012, with a mission to investigate the habitability of the planet. Curiosity has a suite of instruments that can analyze rocks, soil, and air samples, as well as take photos and videos. Curiosity has found evidence of ancient rivers, lakes, and organic molecules on Mars, suggesting that the planet was once warmer and wetter than it is today. Curiosity is also preparing the way for future human missions to Mars, by testing technologies and studying the environment and radiation levels.

Number 1: Apollo

And finally, the number one spot goes to Apollo, the program that sent humans to the moon for the first time in history. Apollo was launched in 1961 and lasted until 1972, during which 12 astronauts walked on the lunar surface. Apollo was not only a scientific and technological achievement, but also a political and cultural one. It inspired generations of people to dream big and explore the unknown. Apollo also brought back valuable samples and data from the moon, which are still being studied today.
