Shenzhou-10 spacecraft will be launched at Jiuquan Satellite Launch Center from June to August this year. Three astronauts will rendezvous and dock with the Tiangong-1 target aircraft on the spacecraft to transport personnel and some materials for the Tiangong-1 target aircraft. This manned rendezvous and docking indicates that China has a practical transportation system between heaven and earth.

Test analysis: first of all, the answer should be divided into main sentences and additional components. The main sentence of this question is that manned rendezvous and docking indicates that China has a practical transportation system between heaven and earth. Secondly, we should turn the additional components into three short sentences, and pay attention to the requirements of the stem. The short sentence beginning with "Shenzhou-10 spacecraft" should be the first sentence, and the four rewritten short sentences must be fluent and coherent, with clear meaning and clear original intention.
