English: This is the first image taken by NASA's InSight lander on the surface of Mars. The instrument context camera (ICC) mounted below the lander deck obtained this image on Nov. 26, 2018, shortly after landing. The transparent lens cover was still in place to protect the lens from any dust kicked up during landing.
1080p (1920 × 1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; [1] the p stands for progressive scan, i.e. non-interlaced.
Three types of pictures (or frames) are used in video compression: I, P, and B frames. An I‑frame (intra-coded picture) is a complete image, like a JPG or BMP image file. A P‑frame (Predicted picture) holds only the changes in the image from a previous frame. For example, in a scene where a car moves across a stationary background, only the ...
Windows Spotlight images are provided by Windows' Content Delivery Manager. New ones are shown every 1–2 days. Downloaded images are stored in JPEG format on the computer. [1] If the Content Delivery Manager has no new picture to display, a default image is used. This default fallback image can be changed. [2]
Apollo 7 slow-scan TV, transmitted by the RCA command module TV camera. NASA decided on initial specifications for TV on the Apollo command module (CM) in 1962. [2] [ Note 1] Both analog and digital transmission techniques were studied, but the early digital systems still used more bandwidth than an analog approach: 20 MHz for the digital system, compared to 500 kHz for the analog system.

480p is the shorthand name for a family of video display resolutions.The p stands for progressive scan, i.e. non-interlaced.The 480 denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio (480 × 4 ⁄ 3 = 640) or a horizontal resolution of 854 (848 should be used for mod16 compatibility) [1] pixels for an approximate 16:9 aspect ...
Here we report on the geology and subsurface structure of the landing site to aid in situ geophysical investigations. InSight landed in a degraded impact crater in Elysium Planitia on a smooth sandy, granule- and pebble-rich surface with few rocks. Superposed impact craters are common and eolian bedforms are sparse.
