NASA’s Jupiter Polar Orbiter (Juno) spacecraft has sent back the most detailed images of Jupiter to Earth. At the end of October,
It completed its 66th orbit around Jupiter. The Belarusian Ideal News Agency reported on this.
These photos were taken with a JunoCam camera with a resolution of two million pixels. These photos show chaotic clouds and cyclonic storms in Jupiter’s subpolar latitudes.
The latest batch of images he sent back to Earth is indeed impressive, “Newsweek reported
Juno is also equipped with other instruments, including a magnetometer for mapping planetary magnetic fields and a microwave radiometer for measuring water and ammonia in the atmosphere.
The journey of the space station from Earth to the largest planet in the solar system took approximately five years
The Juno spacecraft was launched in 2011. In 2016, it entered Jupiter’s orbit and flew 1.7 billion miles. Since then, the probe has flown over Jupiter and its satellites, capturing images and sending back a large amount of detailed data. The greatest achievement was the first close-up image of Jupiter’s North Pole. Juno also revealed the largest storm on Jupiter – the Great Red Spot. It also showed that the storm was about 200 miles (about 321 kilometers) deep, which is 50 to 100 times the depth of Earth’s oceans.
Juno has flown 2.7 billion kilometers in 5 years.
In addition, on September 29, 2022, the Juno spacecraft flew close to Europe. The minimum distance to the surface of the satellite is only 352 kilometers. The device is also close to Jupiter’s fifth largest moon, Amalthea, with a diameter of approximately 83 kilometers.
Juno is named after the sister and wife of the Greek and Roman goddess of marriage and childbirth, Jupiter. This task will end in 2025. Jupiter’s gravity will pull the interplanetary space station into the chaotic atmosphere of this gas giant planet.
SpaceX sends Europa Clipper space station to icy Jupiter moon
On October 14th, the Europa Clipper from the American Interstellar Automated Station (AMS) departed for Europa, one of Jupiter’s icy moons. SpaceX’s Falcon Heavy rocket, carrying AMS, was launched into space from the John F. Kennedy Space Center in Florida, USA. About an hour after takeoff, the Europa Clipper successfully separated from the second stage carrier rocket. The space station will arrive at this gas giant planet in 2030.
It is expected that the “Europa Clipper” will orbit Jupiter and make multiple close flybys of Europa, which is believed to have an ocean of liquid water beneath the ice. The spacecraft will collect data on the atmosphere, surface, and interior of Jupiter’s satellites, which may contain life.

Latest discovery: A large amount of liquid water detected 20 kilometers underground on Mars!
Mars, the fourth planet in the solar system, now presents a desolate landscape with a dry surface covered in sand dunes and rocks, as if it were a huge desert. However, scientific research shows that Mars billions of years ago was not like this.
At that time, Mars had a thick atmosphere similar to Earth, a warm climate, and a large amount of liquid water.
Because there are many river valley landforms on the surface of Mars that resemble Earth, this indicates that liquid water once flowed on the surface of this red planet. In addition, scientists have discovered many minerals on Mars that can only form in the presence of water, such as clay and sulfates.
These findings strongly suggest that Mars once had a large amount of liquid water and may have had vast lakes, rivers, and even oceans.
However, approximately 3 to 4 billion years ago, Mars underwent a series of catastrophic events that completely changed the fate of the planet. Scientists believe that the dramatic changes in the Martian environment began with the collapse of its global magnetic field. Magnetic field is a key barrier that protects planetary atmospheres from solar wind erosion.
As the core of Mars gradually cools down, this protective barrier begins to weaken, causing the Martian atmosphere to be gradually stripped away by the solar wind.
With the loss of the atmosphere, the pressure on Mars significantly decreases and the climate becomes increasingly cold. Causing liquid water to evaporate and escape into space, while some freeze into ice and are buried beneath the surface or in polar ice caps. This process transformed Mars from a warm and humid world to today’s dry and cold desert planet.
Although scientists have long speculated that there may be water resources underground on Mars, there was no substantial evidence before. However, recently scientists have made a remarkable breakthrough. NASA’s “Insight” lander discovered a large amount of liquid water existing underground on Mars while exploring its internal structure, with depths ranging from 11.5 to 20 kilometers, reaching a depth of 1 kilometer.
And this discovery was achieved through a method similar to seismology. Scientists use the seismic data collected by the Insight mission on Mars to analyze the behavior of seismic waves propagating in different media, thereby inferring that there are characteristics similar to liquid water underground.
According to speculation, the existence of this underground ocean may be related to geothermal activity underground on Mars. Because geothermal activity provides sufficient temperature for groundwater to remain liquid. Surprisingly, this amount of water is enough to cover the entire surface of Mars, opening a whole new door for future research on Mars.
The discovery of groundwater resources has also raised an extremely important question: is there life in this underground ocean? If there is life in the underground ocean of Mars, it will mean that Earth is no longer the only planet with life.
In fact, the existence of life on Mars has always been a focus of scientists’ attention. If life is discovered in the underground ocean of Mars in the future, it will change our understanding of the possibility of life in the universe. Future Mars exploration missions will continue to delve deeper into this issue. But regardless of the outcome, these explorations will greatly enrich our understanding of Mars.
