Imagine one day , you will be an astronaut who are going to explore the Jupiter and suddenly you meet a alien . Well in my opinion , I think that he or she may be very nice and have a similar figure like in some movies we watch . I think the inhabitants of Jupiter may be very different to human beings. This is how imagine them: They may be much bigger and more powerful than humans. Jupiterians may have eight legs and be able to move very fast. They may have a lot of hair all over their bodies and their skin might be very think so they can live in temperatures of around - 145 degrees Celsius. They may have four eyes and be able to see very far. They may also have a very good sence of smell and they may even be able to sense others’ feelings like happiness or fear. And I don’t think they eat and drink like us. Instead, they get all their energy from the rocks. They may charge their bodies by plugging their feet into the rock, just like charging a battery. That way, they don’t even need to breathe air. The only way they may be similar to us is they live in family units of parents and children. They may also use language to communicate with each other.

This is the schedule for my family's 2-day visit to Hanoi. On the first day, we plan to explore the city on the bus until 11 a.m. After that, we will have lunch at Ha Thanh restaurant. Then, we will spend the rest of the day visiting some historical places such as Ho Chi Minh mausoleum; Temple of Literature. On the second day, we will go to Kangnam tower and spend our time there playing entertainment activities and going shopping. We will leave at 7 p.m that day. I hope that we will have a great time there.

This is the schedule for our group’s 2-day visit to Washington DC. On the first day, we plan to explore the city on a hop-on-hop-off trolley at 9 a.m. Then at 1:00 p.m we plan to visit the White house , where the President of the USA lives. On the second day, we take the shuttle bus to visit the National Children’s museum at 8 a.m. Then at 2 p.m we cycle on bike trails in National park. I hope I can have good time in this city.

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.

There are many types of natural disasters, storms are one of them, a storm is a turbulent state in the atmosphere and a type of extreme weather.There are many types of storms: Snowstorms: a very heavy snow phenomenon. thick with strong winds. Usually occurs in cold or temperate countries. Sand tornado: also known as sand demon, is a phenomenon of sand swept up very high, occurring at noon in desert areas. To: is the phenomenon of wind speeding up suddenly, accompanied by strong thunderstorms. Thunderstorms: are storms accompanied by thunder, heavy rain or hail. Tornado: is a phenomenon of a circular swirling air stream extending from a thunderstorm cloud down to the ground, especially in that a thunderstorm can descend on empty fields (rural areas) and cities. Fire storm: is a way to call intense fires that have created their own convection system and wind, making it extremely large and difficult to control or extinguish. Tropical cyclones are rapidly rotating storm systems characterized by a center of low pressure, strong winds and a spiral cloud structure that produces heavy rain. lots of homes. The bigger the storm, the more loss of life and property. Storms often break trees and damage homes. A hurricane with a tornado can sweep people and houses away, break trees, cause crop damage, and cause accidents to planes and boats. Therefore, we must take timely measures to prevent storms, we must resist our house carefully, so we can prevent a little harm from storm.
