請問世界上最小的火箭叫什麼名字?

您好。

有關世界上最小的火箭,答復如下:

一、
Smallest rocket
Who:The Pegasus rocket
When:April 05, 1990
Details:
The smallest satellite launch vehicle was Pegasus - the three-stage booster was 15.5 m (50 ft 10 in) long. Pegasus has now been succeeded by an operational Pegasus XL version. The original Pegasus, first launched in 1990, was air-launched from an aircraft jet called Stargazer. 
﹝摘譯如下: 最小的衛星運載火箭為Pegasus,有三節推進器,長度為15.5公尺,於1990年4月5日由噴射機上發射﹞

二、
根據本館《新世紀太空百科全書》(貓頭鷹出版;ISBN 9570337974)一書,其第41頁右上角有一「火箭的性能」圖表,其中顯示火箭名稱為「寶馬」的火箭,長度為「15.5公尺」,為同表11種火箭中最短的火箭。「寶馬」應是上述Pegasus之中譯,為希臘神話中的雙翼飛馬。

三、
再根據英文Wikipedia之「Pegasus (rocket)」 http://en.wikipedia.org/wiki/Pegasus_ (rocket) 一詞,則顯示其高度有16.9 m,與上述兩項記載不同。

以下之Q&A,您可以參考看看。
Q:
What is the smallest rocket to have reached space?
A:
Are you talking about manned space flights or just rockets being launched straight up? In terms of American manned space flight, the first rockets were actually missiles. They removed the warhead and put a capsule in its place. The mercury missions were the first into space, and some of them used a redstone missile. The redstone they have on display in cape Canaveral doesn't seem to be much higher than 30-40 feet.
