The world's first space tourist is setting his sights on Mars. Back in 2001, Dennis Tito, a businessman, shelled out about $20 million to ride a Russian spaceship to the International Space Station. Now, he's leading a group that wants to send a man and woman to fly around the red planet. Is that even possible? NPR's Nell Greenfieldboyce reports.
Dennis Tito made a fortune as an investment manager, but he's also an aerospace engineer. In the 1960s, he worked with NASA's Jet Propulsion Laboratory, helping to plot trajectories for robotic missions, including one that flew by Mars. He says while robotic exploration keeps improving, human spaceflight is a different story. It's been four decades since the last manned moon mission, and people haven't ventured out farther.
I've been waiting myself and a lot of other people my age have been waiting and waiting, and I think it's time to put an end to that lapse.世界上第一个宇宙空间旅行者正在将他的视线转移到火星上。早在2001年作为商人的丹尼斯·地多，曾花费两千万美元驾驶俄国航空飞机到达国际空间站。现在，他正在领导一个小组，这个小组计划让一个男人和一个女人环绕这个红色星球飞行。这个可能吗？NPR绿色领域的内尔·博伊斯报告。
丹尼斯·地多曾经通过投资赚了一笔钱，同时他也是一名航空工程师。二十世纪六十年代，他曾在NASA航空火箭推进器实验室协助完成自动轨道设计任务，其中包括一条通往火星的轨道。他说通过自动探测研究的发展，人类的太空飞行将呈现另外一番景象。它将成为即人类登月之后第四项划时代成就，人们还从来没有到达过那么远的地方。
我和与我同龄的人曾经等了很长时间，我想现在是时候让这段等待画上句号了。
