But urban area is not a suitable place for stargazing. So we will go to the suburb to appreciate the stars. </p><p class="ql-block">The navigator shows it is 80 kilometers from here to the destination.

It is located in Bulaotun town,which is a little town of Miyun county.</p><p class="ql-block">Miyun Ground Station, an astronomical observing base built since the 1960’s, is located in the Bulaotun Township to the northern bank of Miyun Reservoir. It currently is equipped with two big radio telescopes, 50m and 40m diameter telescopes, working in S and X dual frequencies. New techniques have been developed, such as cryogenic receiver with low noise temperature, and telescope array data acquisition. </p><p class="ql-block">Miyun Ground Station is responsible for two important tasks in the Lunar and Mars Exploration Program: scientific downlink data receiving and VLBI joint observations. Additionally IPS monitoring in “Meridian Program ” is also carried out. </p><p class="ql-block">Through the execution of Chinese lunar and Mars programs and continued construction, Miyun Ground Station has become a deep space station with the highest receiving capacity in our nation and of international renown.</p><p class="ql-block"><br></p> <p class="ql-block"><b>stargaze</b></p><p class="ql-block">The beautiful thing about staring off into the skies is that you can do so from any continent.

They point to the North star.</p><p class="ql-block">North Star is a very important star because sailors and other travellers use it to help them find their way.</p> <p class="ql-block"><b>Ursa Major</b></p><p class="ql-block">The Ursa Major is the most famous and brightest constellation through all year. While among the four seasons, Spring is the best time to observe it. Once we point out the location of the Big Dipper, the whole Ursa Marjor is easily to recognize. Because the Big Dipper is the tail of the big bear in the sky.</p> <p class="ql-block">This constellation is Leo.</p><p class="ql-block">Leo means lion.</p><p class="ql-block">S: Lion is a carnivore, just like T rex.</p><p class="ql-block">What did you see tonight?</p><p class="ql-block">S: Big dipper, North star, Leo, Ursa Major.👍👍</p> <p class="ql-block">想找找爸爸和森森的星座，最后因为位置不太好，那边的星星都不是很清晰。</p>
