Astronaut Ricky Arnold is shown on his first spacewalk as a crewmember on STS-119.

Before he joined the Astronaut Corps, Arnold was a teacher in classrooms all over the world, from Malaysia to Romania. Arnold also served aboard the International Space Station on Expedition 55/56.

In this image, during the six-hour, seven-minute spacewalk, Arnold and fellow astronaut Steve Swanson (out of frame) connected bolts to permanently attach the S6 truss segment to S5. The spacewalkers plugged in power and data connectors to the truss, prepared a radiator to cool it, opened boxes containing the new solar arrays and deployed the Beta Gimbal Assemblies containing masts that support the solar arrays. The blackness of space and Earth’s horizon provide the backdrop for the scene.

航员瑞奇·阿诺德(Ricky Arnold)作为STS-119机组成员首次进行太空行走。

在加入宇航员队伍之前,阿诺德在从马来西亚到罗马尼亚的世界各地担任教师。阿诺德还曾在国际空间站上参加过第55/56次远征队。

在这张图片中,阿诺德和他的同伴史蒂夫·斯旺森(画面外)在6小时7分钟的太空行走中连接了螺栓,将S6桁架部分永久地连接到S5上。太空行走者将电源和数据连接器连接到桁架上,准备一个散热器来冷却桁架,打开装有新的太阳能电池组的盒子,并部署含有支持太阳能电池组的桅杆的贝塔万向节组件。漆黑的太空和地球地平线为这一场景提供了背景。
