NASA Frequently post height Impressive GIFs glimpse of beyond our own atmosphereanother beauty came this week Mars.

On Thursday, the space agency’s Curiosity rover Two animated images have been released showing the Martian landscape seen by the six-wheeled vehicle over 12 hours. This is essentially what a day on Mars looks like, from sunrise to sunset, with Curiosity capturing its own shadow in the foreground.

“Hey look – I’m a sundial!” Curiosity official account tweeted“Well, not exactly, but I did get a sun to enjoy my surroundings. During the solar conjunction, I used my hazard camera to study the Martian weather and dust.”

You can see the second set of images on NASA’s Mars website.

Curiosity’s photos were taken from 5:30 am to 5:30 pm local time on November 8. Views southeast (front camera) and northwest (rear camera) as seen from Curiosity Curiosity’s latest (and triumphant) arrival at the Gediz Valley ridge — a major stop on its steady climb up Mount Sharp in Gale Crater since 2014.

They were taken using the rover’s front and rear hazard-avoidance cameras, known as danger camera (Cameras not only help robots identify obstacles and tricky terrain, they also bring us Various gorgeous images of Mars). to NASAthe rover was ordered to Mars Sun Conjunctionwhen the sun sat rudely between Mars and Earth and disrupted communications – which is about a two-week period that occurs every two years.

NASA scientists hope to capture some Martian clouds or dust stormWhile they didn’t see any weather conditions in the photos, the stitched clips are a shining example of a Martian day – and Curiosity’s presence in one.

“As the sky brightens during sunrise, the shadow of the rover’s 7-foot (2-meter) robotic arm moves to the left, and Curiosity’s front wheels emerge from the darkness on either side of the frame. Also visible on the left to a circular calibration target mounted on the shoulder of the robotic arm,” Read NASA’s blog post. “Engineers use targets to test their accuracy Alpha particle X-ray spectrometeran instrument that detects chemical elements on the surface of Mars.

“At noon, the front-facing hazard camera’s automatic exposure algorithm sets the exposure time to approximately one-third of a second. By nightfall, the exposure time increases to more than a minute, resulting in typical sensor noise known as ‘ Hot pixels appear as white snow in the final image.”

As for the spots on the camera?Well, you don’t know After 11 years of orbiting Mars, there is no dust on the lens..
