Mars is the site of Olympus Mons, the largest volcano and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature.] Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan.]]> 2017-06-29 11:01:39 UTC https://padlet.com/907210437/3iqln34zaho5/wish/177730953 907210437 https://padlet.com/907210437/3iqln34zaho5/wish/177731506   A Space shuttle can bring us travel to the space like plane, we can use it for traveling]]> 2017-06-29 11:08:45 UTC https://padlet.com/907210437/3iqln34zaho5/wish/177731506 907210437 https://padlet.com/907210437/3iqln34zaho5/wish/177731819 A mars rover have wide wheels, it can make sure we can drive it on the ground of mars.]]> 2017-06-29 11:14:11 UTC https://padlet.com/907210437/3iqln34zaho5/wish/177731819 907210437 https://padlet.com/907210437/3iqln34zaho5/wish/177732350   The Moon is an astronomical body that orbits planet Earth, being Earth's only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary). ]]> 2017-06-29 11:22:28 UTC https://padlet.com/907210437/3iqln34zaho5/wish/177732350 907210437 https://padlet.com/907210437/3iqln34zaho5/wish/177732821 The Moon is in synchronous rotation with Earth, always showing the same face, with its near side marked by dark volcanic maria that fill the spaces between the bright ancient crustal highlands and the prominent impact craters. It is the second-brightest regularly visible celestial object in Earth's sky, after the Sun, as measured by illuminance on Earth's surface. Its surface is actually dark, although compared to the night sky it appears very bright, with a reflectance just slightly higher than that of worn asphalt. Its prominence in the sky and its regular cycle of phases have made the Moon an important cultural influence since ancient times on language, calendars, art, and mythology.]]> 2017-06-29 11:31:23 UTC https://padlet.com/907210437/3iqln34zaho5/wish/177732821 907210437 https://padlet.com/907210437/3iqln34zaho5/wish/177732897   A Lunar rover can make us traveling on the moon very lightly]]> 2017-06-29 11:32:57 UTC https://padlet.com/907210437/3iqln34zaho5/wish/177732897 907210437 https://padlet.com/907210437/3iqln34zaho5/wish/177937345   The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,34420 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.^[7]]]> 2017-07-03 10:17:31 UTC https://padlet.com/907210437/3iqln34zaho5/wish/177937345 907210437 https://padlet.com/907210437/3iqln34zaho5/wish/177938139     The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.]]> 2017-07-03 10:28:49 UTC https://padlet.com/907210437/3iqln34zaho5/wish/177938139
