世界上最快的人造飞行器是大名鼎鼎的 “新地平线”号探测器。它要踏上一段航程约 50亿千米，时间长达9年半的漫漫征途。
在发射升空大约45分钟后，“新地平线” 号成功与运载火箭分离。它的时速高达约5.8 万千米/小时(约16千米每秒)，这是迄今为 止人类发射的速度最快的太空飞行器。它的 速度来自于美国“宇宙神”火箭，所以飞得 最快的飞行器应该是“宇宙神”火箭!
也许你会觉得制造如此高速的飞行器肯 定耗资巨大，其实一整套的探测计划的总预 算才7亿美元。
The world's fastest man-made aircraft
The world's fastest man-made aircraft is the famous "New Horizons" spacecraft. Itis necessary to embark on a journey of about 5000000000 km, for as long as 9 and a half years of a long journey.
In about 45 minutes after launch, "separation of new horizon is successful with the launch vehicle. It can reach speeds of up to about 5.8 thousands of meters /hour (about 16 kilometers per second), this is by far the fastest human launch ofspacecraft. The speed of it from the United States Atlas rocket, so the fastest flying aircraft should be "the atlas rocket!
Perhaps you will feel making such high-speed aircraft will in fact the total pre exploration program is a set of only $700000000.(责任编辑：最有料)
