This is a montage of New Horizons images of Jupiter and its volcanic moon Io, taken during the spacecraft’s Jupiter flyby . The image was released in Oct. 2007. (Image credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute) Jupiter's fifth moon, Io, is the most volcanically active body in the solar system. Plumes of sulfur spew upward as high as 190 miles (300 kilometers). The surface of Io is splotched with lava lakes and floodplains of liquid rock. Astronomers have mapped about 150 volcanoes on the moon, some of which blast lava 250 miles (400 km) out into space. There are volcanoes all over Io's surface, and as scientists perform observations they still occasionally see new hotspots pop up. For example, NASA's Juno spacecraft, which is currently orbiting Jupiter, found a possible new hotspot on Io on Dec. 16, 2017. Io by the numbers Age: Io is about 4.5 billion years old, about the same age as Jupiter. Distan...

Ganymede is the largest moon in the solar system, and is larger than the planet Mercury. If it were not orbiting as Jupiter’s largest moon, it could be considered a dwarf planet. Ganymede is the only moon in the solar system known to have a substantial magnetosphere. That implies there is something inside helping to generate a strong magnetic field. Like Europa, Ganymede is thought to have a subsurface ocean, overlying a liquid iron and nickel core. That core is what helps generate the magnetic field. The surface of Ganymede is icy and covered with two main types of landscape: young, lighter regions and darker, older and cratered terrain. The dark areas appear to contain clays and organic materials. Ganymede was likely formed in place around the infant Jupiter in the early solar system. Several smaller worlds likely accreted together to make this moon. Ganymede has a thin atmosphere that a...

It has been very interesting to explore new planets and stars, If we talk about Europa, It is so smaller than Earth. It's actually a Moon of Jupiter. there is no evidence that life exists on Europa, but Europa has emerged as one of the most likely locations in the Solar System for potential habitability. Life could exist in its under-ice ocean, perhaps in an environment similar to Earth's deep-ocean hydrothermal vents. The Chemical Elements of life might be under the surface of Europa, because The surface of Europa was destroyed by Jupiter's Radiation, But that radiation might have helped life to live under the surface of Europa. Europa's most of the surface is made of Ice and we have a strong evidence that there is a deep ocean under the surface of Europa. The scientists have said that there are strong possibilities of life on Europa.

Callisto has an exceptionally slim environment, is thought to contain a sea, and is in this way one more conceivable competitor for life past Earth. Notwithstanding, its separation from Jupiter implies it doesn't experience a particularly solid gravitational draw, so it's not as geographically dynamic as the other Galilean moons of Io and Europa. Albeit some have conjectured that life might be conceivable inside the air of Jupiter itself, more probable competitors are the four frigid Galilean moons around it. Every one of the four moons are amazingly cold, and all have slim environments. In any case, they are for the most part enticing possibilities for discovering life past Earth.

Since NASA's decision, Blue Origin has filed a protest, offered to cover up to $2 billion for the first two years of production of a moon lander, and posted an infographic on its website describing SpaceX's Starship as "immensely complex and high risk." So far, there's no sign that NASA will reverse its decision. Musk has continued to poke fun at Bezos for Blue Moon. After Blue Origin unveiled its lunar lander model in 2019, Musk tweeted: "Putting the word 'Blue' on a ball is questionable branding." Musk later posted a screenshot of a New York Times article on which he changed the name from "Blue Moon" to "Blue Balls."

In January 2015, SpaceX raised US$1 billion in funding from Google and Fidelity, in exchange for 8.33% of the company, establishing the company valuation at approximately US$12 billion. SpaceX is developing a satellite megaconstellation named Starlink to provide commercial internet service. In January 2020 the Starlink constellation became the largest satellite constellation in the world. SpaceX is also developing Starship, a privately funded, fully reusable, super heavy-lift launch system for interplanetary spaceflight. Starship is intended to become the primary SpaceX orbital vehicle once operational, supplanting the existing Falcon 9, Falcon Heavy and Dragon fleet. Starship will be fully reusable and will have the highest payload capacity of any orbital rocket ever on its debut, scheduled for the early 2020s.
