NASA’s Curiosity Rover has captured a stunning picture of rays from the setting solar at twilight on Mars. The picture, which marks the primary time solar rays have been considered clearly over the Purple Planet, was captured by the robotic rover on Feb. 2, 2023.
The sunshine often known as “crepuscular rays” from the Latin phrase for “twilight,” may be seen illuminating a financial institution of clouds over Mars.
The picture happened as a part of the Curiosity rover‘s new mission on Mars: Observing clouds over the planet throughout its twilight hours. The brand new investigation builds upon earlier observations of Martian clouds throughout nighttime, often known as “noctilucent” or night-shining clouds, performed by the veteran rover which has been exploring the Purple Planet since August 2012.

The clouds featured on this new picture are totally different from different Martian clouds which often hover over the Purple Planet at an altitude no increased than 37 miles (59 kilometers). These twilight clouds are at a better altitude the place the sky over Mars is particularly chilly indicating that the clouds on this picture could also be composed of frozen carbon dioxide, also referred to as “dry ice.”
By finding out clouds Curiosity is offering scientists with important details about the climate on Mars and the composition and temperature of the Martian ambiance. Cloud research can even reveal particulars of the winds that move over the planet’s floor.
The 2021 survey of Mars’ noctilucent clouds was performed utilizing Curiosity’s black and white navigation cameras which had been in a position to present an in depth have a look at cloud constructions as they moved throughout the Martian skyline.
This new twilight survey, which started in January 2023 and can run till mid-March this yr, produces colour photos because of additionally incorporating Curiosity’s colour Mast Digicam (Mastcam). A have a look at the clouds in colour could assist researchers decide how cloud particles collect over time.
Additionally as a part of this observing marketing campaign simply after sundown on Jan. 27, 2023, Curiosity additionally captured an attractive picture of a feather-like cloud over Mars. The colour capacities of Mastcam allowed the rainbow-like, or iridescent, qualities of the cloud to shine.
“The place we see iridescence, it means a cloud’s particle sizes are equivalent to their neighbors in every a part of the cloud,” Area Science Institute atmospheric scientist Mark Lemmon stated in an announcement (opens in new tab). “By colour transitions, we’re seeing particle dimension altering throughout the cloud. That tells us about the best way the cloud is evolving and the way its particles are altering dimension over time.”
Each the twilight cloud and feather-like cloud photos are panoramas which are created by stitching collectively 28 photos captured by Curiosity after which beamed to Earth.
