Yes, I want to live on another planet when the Earth is too crowded. Because it can be a chance to help people become stronger and more flexible. There will be more opportunities to explore a new ecosystem with new resources. In addition, on another planet, humans are also going to develop new technology and new vehicles, such as flying cars or teleporting portals to better our life.
My ideal planet for humans to live on would provide a suitable amount of energy and heat for life to thrive. I suppose that we will be taller, stronger and more intelligent in our new life. The planet would have a diverse range of landscapes, which has a comfortable climate that was not too extreme, with plenty of freshwater sources and a variety of plant and animal species to support a healthy ecosystem. I expect that the inhabitants will have a strong sense of community and a deep connection to the natural environment, with a shared commitment to preserving the planet for future generations. In terms of technology, humans will invent advanced infrastructure to support modern living, including reliable communication networks, efficient transportation systems, and sustainable sources of energy.

There are some conditions that planets must have to support human life on them. First, the most important condition is that there must be enough liquid water on the planet. Second, the planet must hold an atmosphere. And the planet must have enough oxygen in the air for people to survive.
There's no place like home. We have yet to find another planet that fits us so perfectly. So, my first choice would be to stay here and fix the insane mess we are making on this planet.

The gas giant Jupiter, the next planet beyond Mars in the solar system, is inhospitable to life in any currently imaginable form. But its icy moons – especially Europa – have potential. A number of missions have flown past Jupiter and its moons on route to other places, but Nasa’s Galileo mission was the first designed to specifically orbit the planet and study its moons. It collected images and data in the Jovian system from 1995 to 2003, passing Europa 12 times.
Jupiter’s moon Europa is one of the most likely places to harbour life outside Earth, with its liquid oceans and gravitational energy sources
Pictures and data collected by this spacecraft suggest that Europa has a layered structure like Earth: an iron-rich core, a rocky mantle and a crust of ice. Magnetic field measurements found an electric current inside, consistent with a salty liquid ocean beneath the thick crust of ice around the whole planet. Photographs showing huge cracks in the ice, taken by the same mission, support this idea.
Europa’s surface resembles Earth’s sea ice in Antarctica, explains François Poulet from the Institute of Space Astrophysics at the Université Paris-Sud in France: ‘It indicates that the ice is geologically pretty young and it could be proof of its interaction with a reservoir of liquid water.’ In December 2012, the Hubble Space Telescope also detected water vapour above Europa’s South Pole and it was proposed this came from erupting water plumes. Spacecraft have not yet seen these plumes, however, so if they do exist they must be intermittent.
So, Europa probably has water. But what about the other two necessary components to be habitable? It has a source of heat energy coming from the friction of being pulled towards Jupiter’s gravitational field by different amounts during different stages of its elliptical orbit. There is also plenty of radiation around Jupiter to potentially start chemical reactions (strong enough to also very quickly destroy any organic compound formed). But whether it has the correct raw chemical ingredients isn’t yet known; modelling suggests that it might, but more hard data is needed.
In 2022, both the European Space Agency (ESA) and Nasa plan to launch spacecraft that will get up close and personal with Europa. ESA’s Jupiter Icy Moons Explorer (Juice) will take over seven years to reach the Jovian system. ‘We will arrive at the end of 2029 and start operation during 2030,’ says Poulet, a member of the team developing the visible and infrared spectrometer onboard called Majis (Moons and Jupiter Imaging Spectrometer). The main target of the Juice mission is Ganymede, another of Jupiter’s moons, but Europa will receive two flybys. Majis will characterise the surface composition of this moon and – together with the UV spectrometer onboard – determine the composition of Europa’s very thin atmosphere. Other cameras and spectrometers will also help build understanding of this icy world’s interior and crust.
For Nasa’s Europa Clipper mission, Europa is the star of the show. While the seemingly obvious mission would be to orbit Europa for a few years, any spacecraft doing this would be exposed to life-shortening radiation from Jupiter. Instead, Europa clipper will orbit Jupiter, dipping in and out of its radiation belt. It will carry out at least 45 close flybys of Europa over three and a half years. A mixture of cameras and spectrometers will examine the moon and its tenuous atmosphere. If the water plumes above the South Pole do exist, it will also be able to fly through these and therefore directly measure the chemical composition of the moon’s ocean. If the Europa Clipper launches in 2022, there are two possible arrival times for it: 2025, if Nasa’s new Space Launch System (SLS) that is currently in development is used, or January 2030, if a traditional rocket is used.

I would like to tell you about Mercury. It is the smallest planet. It is the closest planet to the sun, and it doesn’t have any moons. It is hot in the daytime but very cold at night. Mercury doesn’t have atmosphere so there is no wind or weather.
