有史以来第一次,美国宇航局已经捕获了火星表面上的流动站登陆视频,加上着陆后的风吹过它的风吹吹口哨 - 而亚马逊网络服务在制作所有这些千兆字节的关键作用世界。

The stars of the show are NASA’s坚持不懈的流浪者和hundreds of scientists and engineers supporting the mission to Mars at NASA’s Jet Propulsion Laboratory and other institutions around the world. But the fact that通过NASA的网站将成千上万的图像泵出来只有很少的打嗝可以说是AWS的表现证明。

“AWS很自豪能够支持NASA JPL的坚持使命,”亚马逊卡尔森,亚马逊网络服务“副总裁全球公共部门和行业,今天在博客帖子中说。“From the outset, AWS cloud services have enabled NASA JPL in its mission to capture and share mission-critical images, and help to answer key questions about the potential for life on Mars.”

戴夫·克鲁斯表示,在普遍的稀释者的最后几分钟内收集了超过23,000兆的图像,达到了30千兆字节的数据,在普遍存在的时间里,Camera Suite表示,在JPL进入,下降和降落。

从航天器的后壳中向上抬头了几相机,以记录降落伞的部署。另一台相机从“天空起重机”下降舞台看,观看流动站的触地得分。与此同时,虎上的相机抬头看着天空起重机,望着它来调查其周围环境。

所有这些观点都放在一起三分钟的视频that documented the milestones of the descent, from the time the parachute popped open to the rover’s dusty touchdown. At the end, video from the rover shows the descent stage flying away to its safe disposal, powered by aset of thrusters built by Aerojet Rocketdyne in Redmond, Wash.

“It gives me goosebumps every time I see it,” Gruel said at today’s news briefing, conducted under COVID-19 conditions at JPL in Pasadena, Calif. “I hope everybody kept their hands and arms inside the vehicle at all times while it was in motion.”

这并非全部:修改后的离心麦克风被钩住了流动站,目的是在下降期间记录空气吹口哨的声音。

No sounds were recorded as the rover dropped, but once Perseverance had settled on its landing spot, the microphone captured the rumble of Martian wind gusts.

稀烂说,声音的特点表明阵风在大约11英里/小时(每秒5米)吹来。狗万平台

副工程经理Matt Wallace表示,随着使命的收益,麦克风可以在流动的车轮下面捕捉到火车车轮下方的岩石。

视频和音频都为NASA打破了新的地面:虽然过去的空间奥德赛中有下降图像,但包括Apollo moon missions火星好奇风车使命, this was the first time a robotic video camera clearly captured the moment of touchdown on another planet.

至于侦听,苏联兰地记录在金星表面上的声音,欧洲航天局抓获sound samples during the Huygens lander’s descent to the surface of Titan和美国国家航空航天局的火星洞察着陆器使用气压传感器记录风振动。但坚持不懈的是第一个直接用麦克风拿起火星风的声音。

Thomas Zurbuchen, NASA’s associate administrator for space science, said this is “how it feels to make history.”

“The video of Perseverance’s descent and landing, and the amazing panorama and the first wide landscape shot of Jezero Crater seen with human eyes, and the first Martian sounds are the closest you can get to landing on Mars without putting on a pressure suit,” Zurbuchen said.

释放原始图像,视频和声音应该冒出想象力 - 不仅适用于未来的空间任务,而且在地球上有创意众包。

“请去看看这些数据并与他们一起玩,特别是你的......已经签署了我们的教育运动,”Zurbuchen说。“你能在这些照片中找到什么?谁将用实际的火星声音撰写第一件音乐?“(Does this count?)

During the first couple of days of the mission, there was a fair amount of grumbling about the paucity of pictures released by the Perseverance team. But the situation changed dramatically today: The tally of美国宇航局坚持不懈画廊的原料图像jumped from less than 200 to more than 4,600 over the course of just a few hours.

亚马逊网络服务said NASA is using its cloud computing platform to process image data from Mars, and to power NASA’s火星使命网站。“该网站将能够在任何特定时间扩大以满足需求,其中数百万访客在高峰时期,”Aws说。

Leaders of Perseverance’s science team say they’re already seeing intriguing geological features to dig into, including an assortment of “holey” rocks that could be volcanic in origin.

“如果他们是火山岩,那对我们来说非常重要,因为它可能提供了一个非常好的辐射尺年的机会,或者如果像这样的样品一样恢复到地球,”科学家肯··威廉州的副项目。
