It was designed to study the interior composition of the comet Tempel 1 (9P/Tempel), by releasing an impactor into the comet. What is Deep Impact?ĭeep Impact was a NASA space probe launched from Cape Canaveral Air Force Station on January 12, 2005. On 14 August 2014, scientists announced the identification of possible interstellar dust particles from the Stardust capsule returned to Earth in 2006. The primary mission was successfully completed on 15 January 2006, when the sample return capsule returned to Earth. They range from a few miles to tens of miles wide, but as they orbit closer to the sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.
Seven years Where is the Stardust spacecraft now?Īfter visiting two comets (and returning pieces of one to Earth) and traveling nearly 5.7 billion miles (9.1 billion kilometers), the Stardust spacecraft is at journey’s end./span> What are comets made of?Ĭomets are frozen leftovers from the formation of the solar system composed of dust, rock and ices. How long did Stardust spend exploring space? They were among the first solid bodies to form in the solar nebula, the collapsing interstellar cloud of dust and gas out of which the Sun and planets formed. Of course, their lifespan is much longer than ours. Like ourselves, and every other living being, the stars are born, they live, and they die. Though we could wrongfully believe, Stars won’t shine forever. Without these elements a scientist cannot perform any research work in any field of science./span> What is the importance of comets?Ĭomets are important to scientists because they are primitive bodies left over from the formation of the solar system. According to science, stardust is made of particles remaining from a supernova explosion. Why are scientists interested in collecting stardust?Īnd scientists collect the stardust because the majority of main elements are included in the stardust category. Then, the process will start again, and after millions and millions of years, a new star will be born, and it will contain all the elements of the previous one. We are made of stardust: All of which end up floating in the space, forming a new nebula. A dreamlike, romantic, or uncritical sense of well-being.
