European Space Agency hosts first Mars live stream
The European Space Agency is streaming on YouTube the first live images directly from Mars. Over the course of an hour, new images of Mars are expected about every 50 seconds, according to statement from the agency. Updates will also be available at ESA's Twitter account and the hashtag #MarsLIVE, the agency said. The images, shared on YouTube, ESA's Twitter account and with #MarsLIVE, will show the planet as it has never been seen before, ESA said.
The event is celebrating the 20th anniversary of the launch of the agency's Mars Express orbiter — a mission to take three-dimensional images of the planet's surface to see it in more complete detail. "Normally, we see images from Mars and know that they were taken days before, " said James Godfrey, spacecraft operations manager at ESA's mission control center in Darmstadt, Germany, in a statement. "I'm excited to see Mars as it is now — as close to a martian 'now' as we can possibly get!"
But haven't we seen images of Mars before? Yes, but not live, the ESA said. Often data and observations of the red planet are taken when a spacecraft is not in direct contact with Earth, so the images are stored until they can be sent back, ESA said. Depending on where Mars and Earth are in their orbits around the sun, the messages that journey through space can take anywhere from 3 to 22 minutes. The ESA estimated it would take about 17 minutes for the light needed to form the images to travel directly from Mars to Earth and then another minute to get through the wires and servers on the ground to get the livestream started, the agency said.
欧洲航天局首次举办火星直播
精听党背景导读
欧洲空间局（ESA）于6月2日尝试了有史以来第一次从另一颗星球——火星进行直播，尽管从地球到火星的距离意味着直播将有短暂的延迟。
这1个小时的直播，使用的是ESA火星快车轨道飞行器上曾经过时的相机。然而，由于地球和火星之间的遥远距离，这些相机拍摄的图像需要17分钟才能到达地球，并且再过1分钟才能通过地面上的各种接收器和服务器播出，因而使得它不太“实时”。

但我们以前没有见过火星的照片吗? 欧洲航天局说，我们以前其实见过火星的照片，但不是以现场直播的形式见到的。欧洲航天局表示，通常情况下，火星的数据和观测都是在航天器与地球没有直接联络时拍摄的，所以这些图像会被储存起来，直到它们被传回地球为止。根据火星和地球在太阳轨道上的位置，信息在太空中的传播可能需要3到22分钟。欧洲航天局估计，形成图像所需的光线直接从火星传播到地球需要大约17分钟，然后再花一分钟通过地面上的电线和服务器开始直播，该机构说道。

由于传输天线所在地西班牙遇到雨天，“火星快车”的直播多次中断，最终呈现给观众的火星图像也比预计的要少。不过，欧洲航天局仍对这次直播表示满意。欧洲航天局说，从这么远的距离向地球传回实时图像几乎前所未有。
欧洲航天局直播前发表声明说，人类发起的太空探索项目中，向地球传回实时图像的项目并不多，包括美国的阿波罗登月计划以及美国国家航空航天局去年用航天器撞击小行星改变其运行轨道的一个项目。声明说，那些项目距离地球相对较近，也有少数距离较远的探索任务发回一两幅实时图像，但像“火星快车”这样“在深空长时间直播”尚属首次。
由于担心长时间直播加重“火星快车”电池负担，欧洲航天局只安排了1个小时的直播。
在直播传回的图像中，火星最初只有三分之一可见，后来慢慢变大，然后又逐渐变小。欧洲航天局操作“火星快车”的工程师西蒙·伍德说，如果人们当时乘坐“火星快车”环绕火星飞行，这就是他们能看到的景象。在其中几幅图像中，白色的云朵清晰可见。
“火星快车”2003年6月发射升空，同年12月25日进入环火星轨道，至今仍在环绕火星飞行。“火星快车”携带的火星着陆器“猎兔犬2”号于2003年12月失联，直到2015年1月经美国航天局的火星勘测轨道飞行器拍摄的高分辨率图像证实，其确实已成功在火星表面着陆，不过此后的故障导致其无法与地球联系。
