60年前，在太空时代即将到来之际，美国宇航局的控制人员“点燃了蜡烛”，将水星宇航员艾伦·谢泼德（Alan Shepard）送上了红石火箭。他狭小的太空舱被命名为“自由7号”。具有历史意义的水星-红石3号（mr3）宇宙飞船于上午9点34分从佛罗里达州卡纳维拉尔角发射，向全球电视观众进行了现场直播。美国东部时间1961年5月5日。自由7号的飞行是美国人的第一次太空飞行，在苏联宇航员尤里·加加林首次进入太空后不到一个月。15分钟的亚轨道飞行达到了116英里的高度和每小时5134英里的最高速度。当Shepard在接近自由7号飞行轨迹的顶点时，他可以看到佛罗里达西海岸、佛罗里达中部的奥基乔比湖、墨西哥湾和巴哈马群岛的轮廓。谢泼德后来从更遥远的角度看待地球，并作为阿波罗14号任务的指挥官在月球上行走。

Sixty years ago, near the dawn of the space age, NASA controllers "lit the candle" and sent Mercury astronaut Alan Shepard arcing into space atop a Redstone rocket. His cramped space capsule was dubbed Freedom 7. Broadcast live to a global television audience, the historic Mercury-Redstone 3 (MR-3) spacecraft was launched from Cape Canaveral Florida at 9:34 a.m. Eastern Time on May 5, 1961. The flight of Freedom 7, the first space flight by an American, followed less than a month after the first human venture into space by Soviet Cosmonaut Yuri Gagarin. The 15 minute sub-orbital flight achieved an altitude of 116 miles and a maximum speed of 5,134 miles per hour. As Shepard looked back near the peak of Freedom 7's trajectory, he could see the outlines of the west coast of Florida, Lake Okeechobe in central Florida, the Gulf of Mexico, and the Bahamas. Shepard would later view planet Earth from a more distant perspective and walk on the Moon as commander of the Apollo 14 mission.
