2021年9月6日 Firefly Milky Way over Russia Image Credit & Copyright: Anton Komlev Explanation: It started with a pine tree. The idea was to photograph a statuesque pine in front of the central band of our Milky Way Galaxy. And the plan, carried out two months ago, was successful — they both appear prominently. But the resulting 3-frame panorama captu...
2021年9月5日 Earth and Moon Image Credit: NASA, JPL, Galileo Project; Processing & License: Gordan Ugarkovic Explanation: The Earth and Moon are rarely photographed together. One of most spectacular times this occurred was about 30 years ago when the Jupiter-bound Galileo spacecraft zoomed past our home planetary system. Then, robotic Galileo watched from ...
This Mastcam-Z image shows a sample of Mars rock inside the sample tube on Sept. 1, 2021 – the 190th sol, or Martian day, of the mission. The image was taken after coring concluded but prior to an operation that vibrates the drill bit and tube to clear the tube’s lip of any residual material. The bronze-colored outer-ring is the coring bit. The lighter...

在这张9月1日导航相机拍摄的两张图片的合成图中，可以看到毅力号第二次样品采集尝试的钻孔。 图片来源：NASA/JPL-Caltech 毅力号在可能完成收集其第一个科学选择的火星样本的过程之前，将获得样本管的额外图像。 9月1日晚间从NASA的毅力号火星车上收到的数据表明，该团队已经实现了对火星岩石成功岩芯采样的目标。这一历史性事件发生后下传的最初图像显示，岩芯采样后样品管内存在一个完整的样本。然而，由于阳光条件不佳，机械臂完成样品采集后拍摄的其他图像并不确定。在继续进行样品处理之前，将拍摄另一轮光线较好的图像。 在进行火星岩石样本的密封和储存之前，获得额外的图像是该团队根据8月5日火星车取样尝试的经验选择加入的额外步骤。尽管毅力号任务团队确信样本在样品管里，但在最佳照明条件下的图像将确认其存在。 毅力号的采样和...
