A murky vista starkly contrasts the shining rays of dying mild; they spill over the horizon and illuminate the clouds. It might be an idyllic scene in lots of locations on Earth, however it didn’t even occur on this planet. NASA has launched new photos from the getting older however seemingly unstoppable Curiosity rover, captured throughout a latest cloud-imaging marketing campaign. Amongst them is the primary detection of solar rays on one other world.

A lot of the robotic exploration on Mars focuses on the floor and the seek for proof of life, however NASA has been wanting skyward these days. Curiosity arrived on Mars in 2012 and started conducting a cloud survey in 2021 utilizing its monochrome navigation cameras. These cameras are adept at following cloud constructions as they drift throughout the horizon. Extra not too long ago, NASA has tasked the colour Mastcam with monitoring clouds, which is good for analyzing particle measurement.

The picture above exhibits rays of daylight, also referred to as crepuscular rays, spreading by the wispy clouds. Mars’s environment is simply 1% as dense as Earth’s, however it nonetheless produces the occasional cloud. Most Martian clouds hover at an altitude of 37 miles (60 kilometers) or decrease. The brand new photos from the Mastcam appear to show cloud formations much higher. That implies they’re composed of carbon dioxide ice relatively than water ice just like the decrease ones.

The second picture exhibits a shiny feather-like cloud. There aren’t any seen crepuscular rays, however the fading daylight has illuminated the cloud and been scattered into an iridescent rainbow. That is one motive NASA makes use of the Mastcam as a substitute of the navigation cameras. Iridescence means the cloud’s particles are the identical measurement in that a part of the cloud. So, monitoring the altering colours throughout the cloud can illustrate the altering particle sizes.

The Mastcam has a complete decision of beneath 2MP, however the cloud panoramas are a lot bigger. NASA captured 28 frames for every panorama after which stitched them collectively to create the full-resolution picture. The sundown occurred on Feb. 2, 2023, the mission’s 3,730th Martian day (or Sol), and the feathery cloud appeared on Jan. 27 (Sol 3,724). NASA solely designed Curiosity to final a couple of years, however there’s no finish in sight for this intrepid robotic explorer.
